Incandescent bulbs are slowly being phased out in favor of more efficient lighting sources. This has led to an increased use of compact fluorescent bulbs which are more efficient than incandescent bulbs, but which tend to contain dangerous gasses, such as mercury. Compact fluorescent bulbs are also affected by ambient temperature and fail reach their peak brightness in colder conditions. Additionally, many people find the color temperature of light emitted by compact fluorescents to not be aesthetically pleasing for many applications, such as household lighting in kitchens, bathrooms, and living rooms; some commercial applications; and the like. Due to the nature of compact fluorescent bulbs, the bulbs always have a frosted appearance, which also tends to reduce the aesthetic appeal of compact fluorescent bulbs. The use of halogen bulbs has also increased; however due to the high temperatures at which halogen bulbs operate they are not highly efficient and may be a fire or burn hazard.
Recent advances in manufacturing light emitting diodes (LEDs) combined with the efficiency and long lifetime of LEDs have led to an increase in the availability and affordability of LED lamps and other LED lighting devices. LED lamps and lighting devices offer advantages over compact fluorescent bulbs including longer lifetime and the absence of dangerous gasses. Also, LED lamps and lighting devices may be configured to emit light at a wide variety of color temperatures.
Therefore, there is a need in the art for LED lighting devices that allow users to take advantage of the wide variety of color temperatures at which LEDs may emit light.
Embodiments of the present invention provide an LED lighting device or LED lamp for which one or more aspects of the light emitted from the LED lighting device or LED lamp (e.g., color temperature, brightness, color rendering index (CRI), and/or the like) is configurable and/or adjustable. For example, the LED lamp or LED lighting device may allow a user to select an operating mode (e.g., a programmable custom mode, a set mode, or a configurable mode). One or more qualities of the light (e.g., color temperature, brightness, CRI, and/or the like) emitted by the LED lamp or LED lighting device may then be controlled based on the user-selected operating mode. For example, a particular LED lamp or LED lighting device may be configured to emit light at a user-selected color temperature. For example, a user may set one or more light aspects or qualities (e.g., brightness, color temperature, CRI, and/or the like) at which the LED lighting device or LED lamp emits light at the time the LED lighting device or LED lamp is installed. Alternatively, the user may select to place the LED lighting device or LED lamp in a configurable operating mode. In the configurable operating mode, a user may use a remote switch (e.g., a wall switch, remote control, mobile computing device, and/or the like) to change the one or more operating light aspects or qualities at which the LED lighting device or LED lamp emits light during the operation of the LED lighting device or LED lamp. For example, the user may use a remote switch to toggle between preset operating light aspects or qualities.
According to one aspect of the present invention, an LED lighting device or LED lamp is provided. In example embodiments, the LED lighting device or LED lamp comprises one or more LED packages; driver circuitry configured to provide a controllable electrical current to at least one of the one or more LED packages during operation of the LED lighting device or LED lamp; a switch comprising at least two selectable options. At least one selectable option corresponds to a set operating mode and one selectable option corresponds to a configurable operating mode. The LED lighting device or LED lamp further comprises a user-selection switch for receiving user-selection of operating light qualities when the switch is in a position to select the configurable operating mode.
According to another aspect of the present invention, an LED lighting device or LED lamp is provided. In example embodiments, the LED lighting device or LED lamp comprises one or more LED packages; driver circuitry configured to provide a controllable electrical current to at least one of the one or more LED packages during operation of the LED lighting device or LED lamp; and a switch comprising at least two selectable options. At least one selectable option corresponds to a set operating mode and one selectable option corresponds to a configurable operating mode. When the LED lighting device or LED lamp is on and when the switch is in a position to select a selectable option corresponding to a set operating mode, the driver circuitry operates at least one of the one or more LED packages to emit light having set operating light qualities corresponding to the set operating mode. When the LED lighting device or LED lamp is on and when the switch is in a position to select the selectable option corresponding to the configurable operating mode, the driver circuitry operates at least one of the one or more LED packages to emit light having operating light qualities corresponding to a most recently received signal indicating a user-selection, the user-selection provided through user interaction with a wall or junction box mounted remote switch.
According to another aspect of the present invention, an LED lighting device or LED lamp is provided. In example embodiments, the LED lighting device or LED lamp comprises one or more LED packages; driver circuitry configured to provide a controllable electrical current to at least one of the one or more LED packages during operation of the LED lighting device or LED lamp; and a switch comprising at least two selectable options. At least one selectable option corresponds to a set operating mode and one selectable option corresponds to a configurable operating mode. When the LED lighting device or LED lamp is on and when the switch is in a position to select a selectable option corresponding to a set operating mode, the driver circuitry operates at least one of the one or more LED packages to emit light having set operating light qualities corresponding to the set operating mode. When the LED lighting device or LED lamp is on and when the switch is in a position to select the selectable option corresponding to the configurable operating mode, the driver circuitry operates at least one of the one or more LED packages to emit light having operating light qualities corresponding to a most recently received signal indicating a user-selection, the user-selection provided through user interaction with a portable remote switch.
Having thus described the invention in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
Example embodiments of the present invention provide an LED lamp or LED lighting device having two or more user selectable modes. Switching between modes may adjust one or more aspects or qualities of the light provided by the LED lamp or LED lighting device when the LED lamp or LED lighting device is operating. For example, switching between modes may adjust the quality of the light provided by the LED lamp or LED lighting device when the LED lamp or LED lighting device is operating. For example, switching between modes may adjust the brightness, color rendering index (CRI), color temperature, and/or the like of the light emitted by the LED lamp or LED lighting device when the LED lamp or LED lighting device is operating.
Example embodiments of the present invention described herein generally relate to an LED lamp or LED lighting device wherein the operating light aspects or qualities (e.g., brightness, color temperature, CRI, and/or the like of the light emitted by the LED lamp or LED lighting device when the LED lamp or LED lighting device is being operated and/or is turned on), is selectively configurable. For example, example embodiments of the present invention described herein generally relate to an LED lamp or LED lighting device wherein the operating color temperature (e.g., the color temperature of the light emitted by the LED lamp or LED lighting device when the LED lamp or LED lighting device is being operated and/or is turned on), is selectively configurable. However, it should be understood that principles of the present invention may be used to provide an LED lamp or LED lighting device for which one or more aspects or qualities of the light provided during operation of the LED lamp or LED lighting device may be modified through selection of a particular mode. Examples of the aspects that may be modified through mode selection may include, but are not limited to, brightness, CRI, color temperature, and/or combinations thereof.
For example, a user may select a desired operating light aspects or qualities (e.g., color temperature, brightness, CRI, and/or the like, and/or a combination thereof) for the LED lamp or LED lighting device before the LED lamp or LED lighting device is installed. Alternatively, the user may select to operate the LED lamp or LED lighting device in a configurable operating mode following installation. For example, the LED lamp or LED lighting device may be operated in a configurable mode that allows a user to change one or more of the operating light aspects or qualities during operation of the LED lamp or LED lighting device using a remote switch. In example embodiments, a remote switch may be a wall mounted switch mounted in the same room as the LED lamp or LED lighting device and/or within a short range communication technology range of the LED lamp or LED lighting device. In another example, the remote switch may be a handheld device (e.g., a remote control) that is within the same room as the LED lamp or LED lighting device, within a short range communication technology range of the LED lamp or LED lighting device, and/or in communication with the LED lamp or LED lighting device through a wireless network.
As noted above, LEDs may be manufactured that emit light at a variety of color temperatures. Moreover, LEDs may be configured to emit light at a variety of brightness, CRI, and/or having other configurable light aspects or qualities. Embodiments of the present invention allow a user to take advantage of the variety of light aspects or qualities at which LEDs may emit light by allowing the user to operate an LED lamp or LED lighting device at a selectable mode such that the user may select and/or modify aspects or qualities of the emitted light. For example, embodiments of the present invention allow a user to take advantage of the variety of color temperatures at which LEDs may emit light by allowing the user to operate an LED lamp or LED lighting device at a selectable configurable operating color temperature. For example, the user may be able to change the operating color temperature of the LED lamp or LED lighting device as the user desires during the operation of the LED lamp or LED lighting device. The user may also choose to select a programmable operating color temperature for the LED lamp or LED lighting device. For example, the LED lighting device or LED lamp may be programmed to a set operating color temperature mode in which the operating color temperature cannot be changed during operation of the LED lamp or LED lighting device. Thus, embodiments of the present invention allow a user to take advantage of the wide range of color temperatures at which LEDs may produce light.
For example, given the wide array of color temperatures and other light aspects or qualities (e.g., brightness, CRI, etc.) available in LED lamps and LED lighting devices, retailers need to stock a variety of different color temperature, brightness, and/or other light aspect or quality options for each style of LED lamp and/or LED lighting device to provide consumers with the options the consumer's desire. Moreover, it is common in multiple purpose rooms (e.g., family rooms, etc.) that different lighting options may be desired. For example, a light having an operating color temperature of 5000 k may be desired if a user is sitting on the couch reading, but the user may prefer a light having an operating color temperature of 3000K when watching television. Traditionally this would require the user to have two lighting options available in the same room. However, example embodiments of the present invention allow the user to have a light source of operating temperature of 3000K and a light source of operating temperature of 5000K while only requiring one lighting device. Similarly, with example embodiments of the present invention, retailers need only to stock LED lamps and/or LED lighting devices based on the style of the lamp and/or lighting device as the operating color temperature and/or other light aspects or qualities of the lamp and/or lighting device are selectable.
In example embodiments, the LED lamp 10 or LED lighting device 20 allows a user to select an operating mode (e.g., a programmable custom mode, a set mode, or a configurable mode). One or more qualities of the light (e.g., color temperature, brightness, CRI, and/or the like) emitted by the LED lamp 10 and/or LED lighting device 20 may then be controlled based on the user-selected operating mode. One or more qualities of the light emitted by the LED lamp 10 and/or LED lighting device 20 may be modified through mode switching (e.g., using switch 30) and/or configured using a remote switch 40 when the user-selected mode is a configurable mode.
In example embodiments, the LED lighting device 20 comprises a device housing 24, a device lens 22, one or more LED packages 18, driver circuitry 19, a switch control unit 35, a switch 30, and/or the like. For example, the device housing 24 may be configured to house the driver circuitry 19; switch control unit 35; one or more LED packages 18; one or more optical elements; one or more heat sink elements; one or more heat dissipation elements; one or more mounting elements configured for mounting the LED lighting device 20 to a ceiling, wall, as a pendant, as a recessed lighting device, and/or the like; one or more stand elements configured for supporting and providing an aesthetic appearance to a luminaire; and/or the like. For example, the switch 30 may be mounted on an exterior surface of the LED lighting device 20. For example, the switch 30 may be mounted on a back, bottom, or otherwise generally hidden surface of the device housing 24 such that the switch 30 is not generally viewable by a user when the LED lighting device 20 is in operation. In some embodiments, the switch 30 may be accessible to the user when the LED lighting device 20 is installed. In such embodiments, the switch 30 may still be generally hidden and/or not located where the switch 30 is easily viewable (e.g., the switch 30 is generally not located on the front of the LED lighting device 20).
In example embodiments the device lens 22 may be transparent, translucent, and/or at least semi-translucent and configured to enclose the optical and/or electrical components of the LED lighting device 20 within the device housing 24. In example embodiments, the electrical components of the LED lighting device 20 (e.g., the driver circuitry 19, switch control unit 35, and/or the like) may be configured to be directly wired to line voltage (e.g., through a junction box) or may be configured to be connected to line voltage through a power cord comprising a two- or three-prong polarized plug.
In example embodiments, the LED lamp 10 or LED lighting device 20 may comprise one or more LED packages 18. In example embodiments, an LED package 18 comprises one or more LED chips, electrical contacts, and optionally phosphor (e.g., to cause the LED package to emit white light). The LED package 18 may further comprise encapsulant to protect the one or more LED chips, wire bonds, and the phosphor. In an example embodiment, the LED packages 18 may comprise one or more alternate current (AC) driven LEDs. In some embodiments, the LED package 18 may further comprise one or more optical elements. In example embodiments, the one or more LED packages 18 may comprise two or more LED packages 18. In example embodiments, the two or more LED packages may comprise at least one first LED package 18a and at least one second LED package 18b. The first LED package 18a may be configured to emit light at a first color temperature and the second LED package 18b may be configured to emit light at a second color temperature. The second color temperature may be different from the first color temperature. For example, the first color temperature may be 3000K or 2700K and the second color temperature may be 5000K. In example embodiments, the two or more LED packages 18 may further comprise a third and/or fourth LED package configured to emit light at a third and/or fourth color temperature, respectively, wherein the third and/or fourth color temperature are different from the first and second color temperatures. For example, in various embodiments, one or more of the LED packages 18 may be configured to emit light of at least one of 2700K, 3000K, 3500K, 4000K, 5000K, 5700K, 6000K, 7000K, 7500K and/or other color temperatures, as appropriate for the application. For example, as shown in
In example embodiments, the two or more LED packages 18 may be in electrical communication with driver circuitry 19 such that the two or more LED packages 18 may be operated by the driver circuitry 19. For example, the driver circuitry 19 may provide a controlled electrical current to at least one of the LED packages 18. For example, the driver circuitry 19 may be configured to only operate first LED packages 18a to cause the LED lamp 10 or LED lighting device 20 to emit light of the first color temperature. In another example, the driver circuitry 19 may be configured to only operate second LED packages 18b to cause the LED lamp 10 or LED lighting device 20 to emit light of the second color temperature. In another example, the driver circuitry 19 may be configured to operate one or more (e.g., half) of the first LED packages 18a and one or more (e.g., half) of the second LED packages 18b to cause the LED lamp 10 or LED lighting device 20 to emit light of a third color temperature. In example embodiments, the first color temperature, second color temperature, and third color temperature may be different from one another. For example, the first color temperature may be 3000K, the second color temperature may be 5000K, and the third color temperature may be 4000K. In some embodiments, the LED lamp 10 or LED lighting device 20 may comprise LED packages 18 configured to emit light at more than two distinct color temperatures (e.g., three, four, or more distinct color temperatures).
In example embodiments, the one or more LED packages 18 may be configured to provide light that varies in brightness, color temperature, CRI, and/or the like based on the current provided to the one or more LED packages 18 by the driver circuitry 19. For example, the driver circuitry may provide a particular current to an LED package 18 to cause the LED package 18 to provide light having particular light aspects or qualities.
In example embodiments, the LED packages 18 may comprise one or more LED packages 18 that are configured to emit light other than “white” light. For example, the LED packages 18 may comprise one or more LED packages 18 configured to emit a red or amber light that may be operated to increase the CRI of the light emitted by the LED lamp 10 or LED lighting device 20.
In example embodiments, the driver circuitry 19 may be configured to provide a controlled electrical current to at least one of the LED packages 18 during operation of the LED lighting device 20 or LED lamp 10. In various embodiments, the driver circuitry 19 may comprise a circuit portion configured to convert AC voltage into DC voltage. In some embodiments, the driver circuitry 19 may comprise a circuit portion configured to control the current flowing through the two or more LED packages 18. In certain embodiments, the driver circuitry 19 may comprise a circuit portion configured to dim the LED lamp 10 or LED lighting fixture 20. In various embodiments, additional circuit components may be present in the driver circuitry 19. Similarly, in various embodiments, all or some of the circuit portions mentioned here may not be present in the driver circuitry 19. In some embodiments, circuit portions listed herein as separate circuit portions may be combined into one circuit portion. As should be appreciated, a variety of driver circuitry configurations are generally known and understood in the art and any of such may be employed in various embodiments as suitable for the intended application, without departing from the scope of the present invention.
In example embodiments, the driver circuitry 19 may be configured to operate subsets of the two or more LED packages 18 at a particular given moment in time. For example, if a first color temperature has been selected by a user as the operating color temperature, the driver circuitry 19 may be configured to operate one or more first LED packages 18a configured to emit light at the selected first color temperature. If a second color temperature has been selected by the user as the operating color temperature, the driver circuitry 19 may be configured to operate one or more second LED packages 18b configured to emit light at the second selected color temperature. If a third color temperature has been selected by the user as the operating color temperature, the driver circuitry 19 may be configured to operate at least a portion of the first LED packages 18a (e.g., half of the first LED packages 18a) and at least a portion of the second LED packages 18b (e.g., half of the second LED packages 18b) to provide (e.g., via a combination of the first and second LED packages) a selected third color temperature that is a composite, mixture, or superposition of the first and second color temperatures. The selection of which LED packages 18 are operated by the driver circuitry 19, when the LED lamp 10 or LED lighting device 20 is operated, is determined by the status of the switch 30 and/or by the switch control unit 35. For example, the driver circuitry 19 may comprise a plurality of provider circuits 17 configured to provide a controlled electrical current to a subset of the two or more LED packages 18 depending on the selected operating color temperature and/or the status of the switch 30.
In another example, the driver circuitry 19 may be configured to provide a particular current to one or more of the LED packages 18 to provide light having specific light aspects qualities (e.g., brightness, color temperature, CRI, and/or the like). For example, the driver circuitry 19 may be configured to drive one or more LED packages 18 such that the LED packages provide light having the desired light aspects or qualities. The determination of how one or more of the LED packages 18 should be driven (e.g., what current should be supplied to the LED packages 18) may be determined by the status of the switch 30 and/or by the switch control unit 35. Based on the desired light aspects or qualities, different LED packages 18 may be driven differently. For example, LED packages 18 may be driven differently from a red or amber LED package 18 that is being operated to increase the CRI of the light emitted by the LED lamp 10 or LED lighting device 20. Thus, the provider circuits 17 may be configured to provide various LED packages 18 with a particular configurable current such that the composite light emitted by the LED lamp 10 or LED lighting device 20 has the user desired light aspects or qualities.
For example, in an example embodiment (with reference to
In example embodiments, various configurations of provider circuits 17 may be applied. For example, as noted above, a provider circuit 17 may be configured to provide electrical current to only the first LED packages 18a, only the second LED packages 18b, or a predetermined combination of the first and second LED packages 18a and 18b. For example, a provider circuit 17 may be configured to provide electrical current to half of the first LED packages 18a and half of the second LED packages 18b to provide light of the third color temperature. In another example, a provider circuit 17 may be configured to provide electrical current to 25% of the first LED packages 18a and 75% of the second LED packages 18b to provide light of a fourth color temperature. It should be understood that a provider circuit 17 may be configured to provide controlled electrical current to various combinations of the first LED packages 18a and the second LED packages 18b to provide various color temperature options. Furthermore, in example embodiments, the two or more LED packages 18 may comprise three or more LED packages 18. For example, the LED packages 18 may comprise at least one first LED package 18a configured to emit light at a first color temperature, at least one second LED package 18b configured to emit light at a second color temperature, and at least one third LED package configured to emit light at a third color temperature, the first, second, and third color temperatures being different from one another. In such an embodiment, a provider circuit 17 may be configured to provide electrical current to at least one of the first LED packages 18a, at least one of the second LED packages 18b, and at least one of the third LED packages to provide a three color blend. It should be understood that LED packages configured to emit light at additional color temperatures may be incorporated into the LED lamp 10 or LED lighting device 20 as desired and/or appropriate for the application and that various combinations of the LED packages may be activated to cause the LED lamp 10 or LED lighting device 20 to emit light of a desired operating color temperature.
As noted above, the light aspects or qualities (e.g., brightness, color temperature, CRI, and/or the like) may be controlled by how the one or more LED packages 18 are operated (instead of and/or in addition to which of the LED packages 18 are operated). In example embodiments, one or more configurable qualities of the light emitted by the LED lamp 10 or the LED lighting device 20 may configured by controlling the current provided to one or more of the LED packages 18. In particular, the driver circuitry 19 may drive the one or more LED packages 18 with a higher or lower current to modify the brightness, color temperature, CRI, and/or the like of the light emitted by the one or more LED packages 18. In another example, the driver circuitry 19 may increase or decrease the number of LED packages 18 being driven to increase or decrease the brightness of the light emitted by the LED lamp 10 or the LED lighting device 20. In another example, one or more red or amber LED packages 18 may be turned on (e.g., electrical current may be supplied thereto by the driver circuitry 19) to increase the CRI of the light emitted by the LED lamp 10 or LED lighting device 20. In another example, the primary or secondary optics used to condition the light emitted by the LED lamp 10 or LED lighting device 20. For example, the optics 13 may be modified, the amount of phosphor through which an LED is emitting may be modified, and/or the like. Thus, in example embodiments, one or more qualities of the light emitted by the LED lamp 10 or LED lighting device 20 may be modified, controlled, configured, and/or the like by changing and/or controlling the amount of current provided to one or more LED packages 18, which LED packages 18 of the two or more LED packages 18 are being operated, physically changing the primary and/or secondary optics conditioning the light, and/or the like. Thus, for example in an embodiment configured to provide configurable brightness settings or modes, the dimming of the LED lamp 10 or LED lighting device 20 may be controlled by the switch control unit 35 and/or driver circuitry 19 rather than by the externally provided current.
In example embodiments, when the LED lamp 10 or LED lighting device 20 is in a configurable operating mode, interaction with the remote switch 40 (e.g., reception of a signal from the remote switch 40) may cause the topology of the driver circuitry to be altered. For example, user interaction with the remote switch 40 may cause a signal to be provided to the switch control unit 35. The switch control unit 35 may then cause a change in the topology of the driver circuitry 19, thereby causing the driver circuitry 19 to operate a different set of LED packages 18, drive one or more LED packages 18 with a modified current, and/or the like.
In example embodiments, the LED lamp 10 and/or LED lighting device 20 comprises a switch 30. In example embodiments, the switch 30 may be configured to allow a user to select an operating mode (e.g., a programmable custom mode, a set mode, or a configurable mode). One or more aspects or qualities of the light (e.g., color temperature, brightness, CRI, and/or the like) emitted by the LED lamp 10 and/or LED lighting device 20 may then be controlled based on the user-selected operating mode. In example embodiments, the switch 30 may be a mechanical switch, electro-mechanical switch, an infrared switch, and/or the like. For example, if the switch 30 is a mechanical switch, the switch 30 may comprise a slide switch, a dial, a set of binary switches, and/or the like. In an example embodiments, the switch 30, and/or a user interface thereof, may be disposed on an exterior surface of the lamp housing 14 or the device housing 24.
In some embodiments, the switch 30 may provide the user with one or more programmable custom operating modes. In an example embodiment, the switch 30 may comprise a custom set operating color temperature mode, in which a user may define and/or select a predefined mixture of the first, second, third, and/or the like operating color temperatures such that the LED lamp 10 or LED lighting device 20 provides a light at the custom set operating color temperature. In another example, the switch 30 may comprise a custom program operating brightness-color temperature operating mode such that the LED lamp 10 or LED lighting device 20 provides light at a custom set operating color temperature at a set brightness. In another example, the switch 30 may comprise a custom program operating mode wherein the switch control unit 35 is configured to cause the operating color temperature, brightness, and/or CRI to change at configurable times (e.g., clock time) or at configurable periods of time. For example, a user may wish to have the LED lamp 10 or LED lighting device 20 operate at one operating color temperature during the morning hours, another operating color temperature during the afternoon, and another operating color temperature in the evening or night time hours. In another example, a user may want the LED lamp 10 or LED lighting device 20 to operate at one operating color temperature, brightness, and/or CRI for the first twenty minutes the LED lamp 10 or LED lighting device 20 is operating and then to operate at another operating color temperature, brightness, and/or CRI for the next three hours or for as long as the LED lamp 10 or LED lighting device 20 remains in constant operation. In example embodiments having programmable custom operating mode options, additional user interface components (e.g., in addition to the switch 30) may be provided for the programming of the programmable custom operating mode. The additional user interface components may be located on the housing 14, 24 of the LED lamp 10 or LED lighting device 20 and/or on a remote switch 40 (e.g., through a mobile computing entity 40′ user interface, wherein the computing entity 40′ is executing an application causing the computing entity 40′ to operate as a remote switch 40). In example embodiments, such additional user interface components may comprise various switches, dials, displays, touchscreen displays, buttons, knobs, and/or the like as commonly understood in the art.
A switch position indicator 33 (e.g., 33a, 33b, 33c, 33d) may correspond to each switch position 32 (e.g., 32a, 32b, 32c, 32d). The switch position indicator 33 (e.g., 33a, 33b, 33c, 33d) may be configured to indicate the operating mode (e.g., color temperature and/or option or mode, etc.) selected by placing the switch selector 34 in the corresponding switch position. For example, switch position indicator 33a may show approximately where the switch position 32a is located and may indicate the color temperature and/or option or mode selected by placing the switch selector 34 in switch position 32a. For example, the switch position indicator 33a indicates that if the switch selector 34 is placed in the switch position 32a, a set operating color temperature mode is selected with the set operating color temperature being 3000K. Similarly, the switch position indicator 33b indicates that if the switch selector 34 is placed in the switch position 32b, a set operating color temperature mode is selected with the set operating color temperature being 4000K; the switch position indicator 33c indicates that if the switch selector 34 is placed in the switch position 32c, a set operating color temperature mode is selected with the set operating color temperature being 5000K; and the switch position indicator 33d indicates that if the switch selector 34 is placed in the switch position 32d, the configurable operating color temperature mode is selected. For example, if the switch selector 34 is placed in switch position 34d, the operating color temperature of the LED lamp 10 or LED lighting device 20 may be configurable by using a wall switch, remote control, and/or the like (e.g., remote switch 40 shown in
In example embodiments, a user may change the operating light aspects or qualities (e.g., operating color temperature, brightness, CRI, and/or the like) of the LED lamp 10 or LED lighting device 20 by changing the positions of the switch selector 34. For example, in various embodiments, the user may change the position of the switch selector 34 while the LED lamp 10 or LED lighting device 20 before installation of the LED lamp 10 or LED lighting device 20, after installation of the LED lamp 10 or LED lighting device 20 but when the LED lamp 10 or LED lighting device 20 is not in use (e.g., is turned off and not emitting light), or while the LED lamp 10 or LED lighting device 20 is in use (e.g., is turned on and is emitting light). In example embodiments, if the position of the switch selector 34 is changed while the LED lamp 10 or LED lighting device 20 is in use, causing the light aspects or qualities thereof to change, the change of the light aspects or qualities may occur within two seconds of the position of the switch selector 34 being changed.
In an example embodiment, a user-selection switch 31 (e.g., a toggle switch, button, and/or the like) may be disposed on the LED lamp 10 or LED lighting device 20 such that user-selection may be received through user-selection switch at the LED lamp 10 or LED lighting device 20. Thus, the user may change the operating light aspects or qualities of the LED lamp 10 or LED lighting device 20 when the LED lamp 10 or LED lighting device 20 is in a configurable operating mode by interacting with the user-selection switch 31 rather than by using the remote switch 40.
In example embodiments, the LED lamp 10 or LED lighting device 20 may comprise a switch control unit 35. In example embodiments, the switch control unit 35 may be configured to cause the driver circuitry 19 to operate one or more LED packages 18 in accordance with the user-selected operating mode (e.g., a programmable custom mode, a set mode, or a configurable mode). In example embodiments, the switch control unit 35 may be a microcontroller unit (MCU). For example, the switch control unit 35 may comprise a single integrated circuit. In example embodiments, the switch control unit 35 comprises one or more processing elements 37, one or more memory elements 36, and/or one or more communication interface elements 38. In example embodiments, the switch control unit 35 may be in wired (e.g., hard-wired) communication with the switch 30 and/or configured to receive signals from the remote switch 40. In example embodiments, the switch control unit 35 may be configured to cause one or more operating light aspects or qualities (e.g., operating color temperature, brightness, CRI) of the LED lamp 10 or the LED lighting device 20 to be modified based on a received signal from the remote switch 40, store information/data identifying the last light aspects or qualities at which the LED lamp 10 or the LED lighting device 20 was operated at, and/or the like. For example, the switch control unit 35 may be configured to receive user selection of a programmable custom operating mode and control the LED lamp 10 or the LED lighting device 20 to operate in accordance with the programmable custom operating mode or other user-selected operating mode (e.g., set operating mode or configurable operating mode).
In example embodiments, the one or more processing elements 37 (also referred to as processors, processing circuitry, processing device, and/or similar terms used herein interchangeably) that communicate with other elements within the switch control unit 35. For example, the processing element(s) 37 may communicate with the memory element(s) 36, communication interface element(s) 38, and/or components of the driver circuitry 19 via direct electrical connection, a bus, and/or the like. For example, the processing element(s) 37 may be configured to process input received through the switch 30 (and/or additional user interface components), process a signal received from the remote switch 40 (e.g., through the communication interface element 38), cause the memory element 36 to store a current operating color temperature, cause one provider circuit 17 to be activated (e.g., to provide a controlled electric current to the corresponding at least one LED package 18), cause another provider circuit 17 to be de-activated (e.g., to stop providing an electric current to the corresponding at least one LED package 18), cause a different and/or modified current to be provided to the provider circuit 17 (e.g., such that the LED package 18 is driven in a modified manner by the provider circuit 17) and/or the like. As will be understood, the processing element 37 may be embodied in a number of different ways. For example, the processing element 37 may be embodied as one or more complex programmable logic devices (CPLDs), microprocessors, multi-core processors, co-processing entities, application-specific instruction-set processors (ASIPs), microcontrollers, and/or controllers. Further, the processing element 37 may be embodied as one or more other processing devices or circuitry. The term circuitry may refer to an entirely hardware embodiment or a combination of hardware and computer program products. Thus, the processing element 37 may be embodied as integrated circuits, application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), programmable logic arrays (PLAs), hardware accelerators, other circuitry, and/or the like. As will therefore be understood, the processing element 37 may be configured for a particular use or configured to execute instructions stored in volatile or non-volatile media or otherwise accessible to the processing element 37. As such, whether configured by hardware or computer program products, or by a combination thereof, the processing element 37 may be capable of performing steps or operations according to embodiments of the present invention when configured accordingly.
The memory element(s) 36 may be non-transitory and may include, for example, one or more volatile and/or non-volatile memories. In other words, for example, the memory element 36 may be an electronic storage device (e.g., a computer readable storage medium) comprising gates configured to store data (e.g., bits) that may be retrievable by a machine (e.g., a computing device like the processing element 37). The memory element 36 may be configured to store information, data, content, applications, instructions, or the like for enabling the switch control unit 35 to carry out various functions in accordance with an example embodiment of the present invention. For example, the memory element 35 could be configured to buffer input data for processing by the processing element 37 (e.g., a signal received from the remote switch 40). In example embodiments, the memory element 36 may be configured to store a most recent operating light aspects or qualities (e.g., color temperature, brightness, CRI, and/or the like, and/or combination thereof). Additionally or alternatively, the memory element 36 could be configured to store instructions for execution by the processing element 37.
As indicated, in one embodiment, the switch control unit 35 may also include one or more communications interface elements 38 for communicating with the remote switch 40. For example, the communications interface element 38 may be configured to receive a signal from the remote switch 40 indicating user selection of, activation of, and/or interaction with an on/off or power button, a dimmer switch, or a remote selector switch configured to select or modify the operating color temperature of the LED lamp 10 or LED lighting device 20, and/or the like. Such communication may be executed using a wired data transmission protocol, such as fiber distributed data interface (FDDI), digital subscriber line (DSL), Ethernet, asynchronous transfer mode (ATM), frame relay, data over cable service interface specification (DOCSIS), or any other wired transmission protocol. Similarly, the communications interface element 38 may be configured to communicate via a wireless communication technology, such as a short range communication technology. For example, the communications interface element 38 may be configured to receive and/or send signals using IEEE 802.11 (Wi-Fi), Wi-Fi Direct, 802.16 (WiMAX), ultra wideband (UWB), infrared (IR) protocols, near field communication (NFC) protocols, Wibree, Bluetooth protocols, wireless universal serial bus (USB) protocols, and/or any other wireless protocol.
In example embodiments, the switch control unit 35 may be configured to cause the LED lamp 10 or LED lighting device 20 to operate at the operating color temperature, brightness, CRI, and/or other particular light aspect or quality, when the LED lamp 10 or LED lighting device 20 is turned on. For example, the switch control unit 35 may be configured to determine the status of the switch 30 and operate the LED lamp 10 or LED lighting device 20 accordingly. For example, the switch control unit 35 may be configured to determine if the position of the switch selector 34 is a position corresponding to a set operating mode, to the position corresponding to the configurable operating mode, and/or to a position corresponding to a programmable custom operating mode. If the switch selector 34 is in a switch position 32 (e.g., 32a, 32b, 32c) corresponding to a set operating mode, the switch control unit 35 (e.g., the processing element 37) may determine the corresponding color temperature (and/or other light aspects or qualities) and cause the LED lamp 10 or LED lighting device 20 to operate at the corresponding color temperature (and/or other light aspects or qualities). For example, if the switch control unit 35 determines that the switch selector 34 is in switch position 32a, the switch control unit 35 may then determine that the corresponding color temperature is 3000K and cause the LED lamp 10 or LED lighting device 20 to be operated at 3000K. For example, if the switch control unit 34 determines that the switch selector 34 is in the switch position 32a, the switch control unit 35 may cause the provider circuit 17 corresponding to the switch position 32a to provide a controlled current to at least one of the two or more LED packages 18.
If the switch control unit 35 determines that the status of the switch 30 places the LED lamp 10 or LED lighting device 20 in the configurable operating mode, the switch control unit 35 may cause the LED lamp 10 or LED lighting device 20 to be operated at light aspects or qualities indicated by the last received signal from the remote switch 40. For example, the memory element 36 may store an indication of the last received signal from the remote switch 40, a current/most recently used operating color temperature, brightness, and/or CRI indicator, and/or the like such that the LED lamp 10 or the lighting device 20 may be operated at the most recently user-selected light aspects or qualities. In another example, if the switch control unit 35 determines that the status of the switch 30 places the LED lamp 10 or LED lighting device 20 in a programmable custom operating mode, the switch control unit 35 may operate the LED lamp 10 or LED lighting device 20 accordingly (e.g., based on a stored custom operating program stored in memory element 36, and/or the like).
In example embodiments, if the status of the switch 30 corresponds to a set operating mode (e.g., a set operating color temperature, brightness, CRI, and/or the like), the switch controller unit 35 may be bypassed. For example, if the switch selector 34 is in switch position corresponding to a set operating color temperature and/or the like (e.g., 32a, 32b, or 32c), the position of the switch selector 34 may cause the appropriate provider circuit 17 to be activated when the LED lamp 10 or lighting device 20 is turned on. For example, the switch position(s) corresponding to a set operating light aspects or qualities may be in direct electrical communication with the corresponding provider circuit 17 such that placement of the switch selector 34 into that switch position causes the corresponding provider circuit 17 to be completed or activated (e.g., when the LED lamp 10 or lighting device 20 is turned on). Thus, in some example embodiments, the switch control unit 35 may not be powered and/or engaged in the operation of the LED lamp 10 or lighting device 20 unless the status of the switch 30 corresponds to a configurable and/or custom programmable mode. In some embodiments, a set operating mode may set one or more light aspects or qualities, while allowing one or more other light aspects or qualities to be configured. For example, a set operating mode may set the operating color temperature and CRI of the LED lamp 10 or lighting device 20 but allow the brightness to be modified. In another example, a set operating mode may set the operating color and brightness of the LED lamp 10 or lighting device 20 but allow the CRI to be modified. For example, in some example embodiments, if the status of the switch 30 corresponds to a set operating color temperature mode, the switch control unit 35 may only be used to receive and process signals from the remote switch 40 and cause corresponding actions related to turning the LED lamp 10 or lighting device 20 on or off, dimming the LED lamp 10 or lighting device 20, modifying the CRI of the LED lamp 10 or lighting device 20, and/or the like. For example, if the switch control unit 35 receives a signal attempting to change the operating color of the LED lamp 10 or lighting device 20 while the LED lamp 10 or lighting device 20 is in a set operating color temperature mode, the switch control unit 35 need not determine if the LED lamp 10 or lighting device 20 is in a set operating color temperature mode or the configurable operating color temperature mode as the switch control unit 35 cannot affect the circuit connection caused by the position of the switch selector 34.
Example embodiments of the present invention comprise a remote switch 40. In example embodiments, a remote switch 40 may be a wall mounted switch mounted in the same room as the LED lamp 10 or LED lighting device 20 and/or within a short range communication technology range of the LED lamp 10 or LED lighting device 20. For example, the remote switch 40 may be a wall and/or junction box mounted toggle switch, dimmer switch and/or the like in wired communication with the switch control unit 35. In another example, the remote switch 40 may be a handheld device (e.g., a remote control, or computing entity 40′) that is within the same room as the LED lamp 10 or LED lighting device 20, within a short range communication technology range of the LED lamp 10 or LED lighting device 20, in communication with the switch control unit 35 through a wireless network, and/or the like. In example embodiments, the remote switch 40 may be in wired or wireless communication with the switch control unit 35. For example, the remote switch 40 may be configured to control the operation of the LED lamp 10 or lighting device 20 or aspects thereof by providing a signal to the switch control unit 35 indicating user selection, interaction, and/or the like with one or more interactive elements of the remote switch 40. For example, the remote switch 40 may be configured to allow a user to toggle through two or more operating color temperatures, brightness, CRIs, and/or other light aspects or qualities of the LED lamp 10 or LED lighting device 20. In example embodiments, the toggling of the remote switch 40 to change or modify the operating light aspects or qualities could be at any time interval from 1 ms to 1 min.
For example, the remote switch 40 may be configured to cause the LED lamp 10 or lighting device 20 to turn on or off, control the brightness of the LED lamp 10 or lighting device 20 (e.g., through a dimmer switch), change the operating light aspects or qualities of the LED lamp 10 or lighting device 20, program a programmable custom operating mode, and/or the like. An example remote switch 40 is illustrated in
The remote switch 40 may further comprise a communication interface 48. In example embodiments, the communication interface 48 may be a part of a control unit that is similar to the switch control unit 35 (e.g., the control unit may comprise a processing element and/or memory element in addition to the communication interface 48). In example embodiments, the communication interface 48 is configured to provide a signal to the communication interface element 38 indicating user selection and/or interaction with the on/off and/or dimmer switch 42, the remote selector 44, and/or the like.
For example, the communications interface 48 may be configured to communicate with the switch control unit 35. For example, the communications interface 48 may be configured to provide a signal to the communications interface element 38 indicating user selection of, activation of, and/or interaction with an on/off and/or dimmer switch 42, remote selector 44, and/or the like. Such communication may be executed using a wired data transmission protocol, such as fiber distributed data interface (FDDI), digital subscriber line (DSL), Ethernet, asynchronous transfer mode (ATM), frame relay, data over cable service interface specification (DOCSIS), or any other wired transmission protocol. Similarly, the communications interface 48 may be configured to communicate via a wireless communication technology, such as a short range communication technology. For example, the communications interface 48 may be configured to receive and/or send signals using IEEE 802.11 (Wi-Fi), Wi-Fi Direct, 802.16 (WiMAX), ultra wideband (UWB), infrared (IR) protocols, near field communication (NFC) protocols, Wibree, Bluetooth protocols, wireless universal serial bus (USB) protocols, and/or any other wireless protocol.

These indoor positioning aspects can be used in a variety of settings to determine the location of someone or something to within inches or centimeters.
The computing entity 40′ may also comprise a user interface (that can include a display 416 coupled to a processing element 408) and/or a user input interface (coupled to a processing element 408). For example, the user interface may be an application, browser, user interface, dashboard, webpage, and/or similar words used herein interchangeably executing on and/or accessible via the computing entity 40′ to interact with and/or cause display of information. The user input interface can comprise any of a number of devices allowing the computing entity 40′ to receive data, such as a keypad 418 (hard or soft), a touch display, voice/speech or motion interfaces, scanners, readers, or other input device.

At block 104, the LED lamp 10 or LED lighting device 20 may be installed. For example, the LED lamp 10 may be secured within a socket of a lighting device. In another example, the LED lighting device 20 may be put into electrical connection with line voltage by plugging a two- or three-prong polarized plug into a wall receptacle and the LED lighting device 20 may be placed in a desired position. In another example, the LED lighting device 20 may be electrically connected to line voltage by connecting wires of the LED lighting device 20 to line voltage wires of a junction box and mounting the LED lighting device 20 to a ceiling, wall, and/or the like.
At some time after the LED lamp 10 or LED lighting device 20 is installed, the LED lamp 10 or lighting device 20 is turned on, at block 112. For example, a user may turn on the LED lamp 10 or LED lighting device 20 by interacting with, selecting, pressing, and/or the like an on/off or power button, switch, and/or the like. For example, the user may interact with, select, press, and/or the like the on/off and/or dimmer switch 42 on the remote switch 40, the remote switch 40 may provide an on/off signal to the switch control unit 35, and the switch control unit 35 may cause the LED lamp 10 or LED lighting device 20 to turn on.
At block 114, it may be determined if the LED lamp 10 or LED lighting device 20 is in a set operating mode. For example it may be determined if the switch 30 was set in a position indicating that the LED lamp 10 or LED lighting device 20 is to be operated in a set operating mode (e.g., with set light aspects or qualities). For example, the switch controller unit 35 (e.g., the processing element 37) may determine if the LED lamp 10 or LED lighting device 20 is in a set operating mode. In some embodiments, determining if the LED lamp 10 or LED lighting device 20 is in a set operating mode does not require an active determination. For example, the switch 30 may be wired such that if the switch selector 34 is in set operating mode switch position, the switch control unit 35 may be bypassed and the provider circuit 17 corresponding to the selected set operating light aspects or qualities may be activated, completed, and/or the like causing the LED lamp 10 or LED lighting device 20 to be operated at the set operating light aspects or qualities.
If, at block 114, it is determined that the LED lamp 10 or LED lighting device 20 is in a set operating mode, the LED lamp 10 or LED lighting device 20 is operated at the set operating light aspects or qualities (e.g., color temperature, brightness, CRI, and/or the like), at block 116. For example, the driver circuitry 19 may operate at least one of the two or more LED packages 18 to cause the LED lamp 10 or LED lighting device 20 to emit light at the set operating color temperature.
If, at block 114, it is determined that the LED lamp 10 or LED lighting device 20 is not in a set operating mode, the process continues to block 118. At block 118, the color temperature that the LED lamp 10 or LED lighting device 20 was last operated at is identified. For example, the switch control unit 35 (e.g., the processing element 37, memory element 36, and/or the like) may identify the color temperature, brightness, CRI, and/or the like that the LED lamp 10 or LED lighting device 20 was last operated at. For example, the memory element 36 may store the most recent operating color temperature, brightness, CRI, and/or the like (and/or an indicator thereof), which may be used to identify the light aspects or qualities that the LED lamp 10 or LED lighting device 20 was last operated at. For example, the identified color temperature is applied or implemented as the operating color temperature.
At block 120, the LED lamp 10 or LED lighting device 20 is operated to provide light having the determined or identified light aspects or qualities. For example, the switch control unit 35 may cause the driver circuitry 19 to operate the LED lamp 10 or LED lighting device 20 at the operating light aspects or qualities (e.g., color temperature, brightness, CRI, and/or the like, and/or a combination thereof). For example, the driver circuitry 19 may operate at least one of the two or more LED packages 18 to cause the LED lamp 10 or LED lighting device 20 to emit light at the operating light aspects or qualities. For example, the driver circuitry 19 may operate a specific set of LED packages 18 to cause the LED lamp 10 or LED lighting device 20 to emit light at the operating color temperature (and/or brightness and/or CRI). In another example, the driver circuitry 19 may drive one or more LED packages 18 such that the LED lamp 10 or LED lighting device 20 emits light at the operating color temperature (and/or brightness and/or CRI). In yet another example, the switch control unit 35 may adjust one or more optical elements to cause the LED lamp 10 or LED lighting device 20 to emit light at the operating color temperature (and/or brightness and/or CRI).
At block 122, it is determined if a light aspect or quality change signal is received. For example, the switch control unit 35 may determine if a light aspect or quality change signal is received from the remote switch 40. For example, the signal may indicate user selection of the color selector 44, indicating the user would like to change the operating color temperature of the LED lamp 10 or the LED lighting device 20. For example, it is determined if a light aspect or quality change signal is received by the communication interface element 38. If, at block 122, it is determined that a light aspect or quality change signal is not received, the process returns to block 120.
If, at block 122, it is determined that a light aspect or quality change signal has been received, one or more operating light aspects or qualities of the LED lamp 10 or LED lighting device 20 are modified accordingly. For example, the switch control unit 35 may activate a provider circuit 17 corresponding to the modified operating color temperature (and/or brightness and/or CRI, and/or the like) and may de-activate the previously activated provider circuit 17 corresponding to the previous operating color temperature (and/or brightness and/or CRI, and/or the like). For example, the switch control unit 35 may cause one provider circuit 17 to provide a controlled electric current to the corresponding at least one LED package 18 such that the LED lamp 10 or LED lighting device 20 emits light having the modified operating light aspects or qualities and cause another provider circuit 17 to stop providing an electric current to the corresponding at least one LED package 18 corresponding to the previous operating light aspect or qualities. For example, the memory element 36 may be updated to indicate the new most recent operating light aspects or qualities. In example embodiments, the switch control unit 35 and/or driver circuitry 19 are configured to start operating the at least one of the two or more LED packages 18 at the modified operating light aspects or qualities within two seconds or less of the receipt of the signal indicating user-selection of the modified operating light aspects or qualities. After the one or more operating light aspects or qualities are modified, the process returns to block 120.
At block 204, the LED lamp 10 or LED lighting device 20 may be installed. For example, the LED lamp 10 may be secured within a socket of a lighting device. In another example, the LED lighting device 20 may be put into electrical connection with line voltage by plugging a two- or three-prong polarized plug into a wall receptacle and the LED lighting device 20 may be placed in a desired position. In another example, the LED lighting device 20 may be electrically connected to line voltage by connecting wires of the LED lighting device 20 to line voltage wires of a junction box and mounting the LED lighting device 20 to a ceiling, wall, and/or the like. In yet another example, a wiring harness terminating in a standard size lamp base connector may be secured into the socket of a recessed lighting fixture. The LED lighting device 20 may then be placed, mounted, installed, and/or the like in a desired position.
At some time after the LED lamp 10 or LED lighting device 20 is installed, the LED lamp 10 or lighting device 20 is turned on, at block 212. For example, a user may turn on the LED lamp 10 or lighting device 20 by interacting with, selecting, pressing, and/or the like an on/off or power button, switch, and/or the like. For example, the user may interact with, select, press, and/or the like the on/off and/or dimmer switch 42 on the remote switch 40, the remote switch 40 may provide an on/off signal to the switch control unit 35, and the switch control unit 35 may cause the LED lamp 10 or LED lighting device 20 to turn on.
At block 214, the color temperature that the LED lamp 10 or LED lighting device 20 was last operated at is identified. For example, the switch control unit 35 (e.g., the processing element 37, memory element 36, and/or the like) may identify the color temperature that the LED lamp 10 or LED lighting device 20 was last operated at. For example, the memory element 36 may store the most recent operating light aspects or qualities, which may be used to identify the color temperature, brightness, CRI, and/or the like that the LED lamp 10 or LED lighting device 20 was last operated at. For example, the identified light aspects or qualities are applied or implemented as the operating light aspects or qualities.
At block 216, the LED lamp 10 or LED lighting device 20 is operated at the operating light aspects or qualities. For example, the switch control unit 35 may cause the driver circuitry 19 to operate the LED lamp 10 or LED lighting device 20 at the operating light aspects or qualities (e.g., color temperature, brightness, CRI, and/or the like). For example, the driver circuitry 19 may operate at least one of the two or more LED packages 18 to cause the LED lamp 10 or LED lighting device 20 to emit light at the operating color temperature. For example, the driver circuitry 19 may operate a specific set of LED packages 18 to cause the LED lamp 10 or LED lighting device 20 to emit light at the operating color temperature (and/or brightness and/or CRI). In another example, the driver circuitry 19 may drive one or more LED packages 18 such that the LED lamp 10 or LED lighting device 20 emits light at the operating color temperature (and/or brightness and/or CRI). In yet another example, the switch control unit 35 may adjust one or more optical elements to cause the LED lamp 10 or LED lighting device 20 to emit light at the operating color temperature (and/or brightness and/or CRI and/or the like).
At block 218, it is determined if a light aspect or quality change signal is received. For example, the switch control unit 35 may determine if a light aspect or quality change signal is received from the remote switch 40. For example, the signal may indicate user selection of the color selector 44, indicating the user would like to change one or more operating light aspects or qualities of the LED lamp 10 or the LED lighting device 20. In another example, the signal may indicate user selection of the dimmer switch 42, indicating the user would like to change the brightness of the light emitted by the LED lamp 10 or the LED lighting device 20. For example, it is determined if a light aspect or quality change signal is received by the communication interface element 38. If, at block 218, it is determined that a light aspect or quality change signal is not received, the process returns to block 216.
If, at block 218, it is determined that a light aspect or quality change signal has been received, it determined if the LED lamp 10 or LED lighting device 20 is in a set operating mode, at block 220. For example it may be determined if the switch 30 was set in a position indicating that the LED lamp 10 or LED lighting device 20 is to be operated in a set operating mode. For example, the switch control unit 35 (e.g., processing elements 37) may determine if the LED lamp 10 or LED lighting device 20 is to be operated in a set operating mode. In some embodiments, determining if the LED lamp 10 or LED lighting device 20 is in a set operating mode does not require an active determination. For example, the switch 30 may be wired such that if the switch selector 34 is in set operating mode switch position, the switch control unit 35 may be bypassed and the provider circuit 17 corresponding to the selected set operating mode (e.g., a set operating color temperature) may be activated, completed, and/or the like causing the LED lamp 10 or LED lighting device 20 to be operated at the set operating light aspects or qualities.
If, at block 220, it is determined that the LED lamp 10 or LED lighting device 20 is in a set operating mode, the process returns to block 216 without modifying the operating light aspects or qualities. If, at block 220, it is determined that the LED lamp 10 or LED lighting device 20 is not in a set operating mode, the process continues to block 222.
At block 222, the operating light aspects or qualities of the LED lamp 10 or LED lighting device 20 are modified in accordance with the received light aspect or quality change signal. For example, the switch control unit 35 may activate a provider circuit 17 corresponding to a modified operating color temperature and may de-activate the previously activated provider circuit 17 corresponding to the previous operating color temperature. For example, the switch control unit 35 may cause one provider circuit 17 to provide a controlled electric current to the corresponding at least one LED package 18 such that the LED lamp 10 or LED lighting device 20 emits light at the modified operating color temperature (and possibly at a modified brightness and/or CRI) and cause another provider circuit 17 to stop providing an electric current to the corresponding at least one LED package 18. For example, the memory element 36 may be updated to indicate the new most recent operating light aspects or qualities. In example embodiments, the switch control unit 35 and/or driver circuitry 19 are configured to start operating the at least one of the two or more LED packages 18 at the modified operating light aspects or qualities within two seconds or less of the receipt of the signal indicating user-selection of the second operating light aspects or qualities. After the operating light aspects or qualities are modified, the process returns to block 216.
In example embodiments, an LED lamp 10 or LED lighting device 20 may be configured to provide a programmable custom operating mode. For example, a user may select a custom operating color temperature (and/or brightness and/or CRI and/or the like) and/or program the LED lamp 10 or LED lighting device 20 (e.g., the switch control unit 35 thereof) to operate the LED lamp 10 or LED light device 20 in accordance with a custom programmed temporal operating program. For example, with reference to
At some time after the LED lamp 10 or LED lighting device 20 is installed, the LED lamp 10 or lighting device 20 is turned on, at block 212. For example, a user may turn on the LED lamp 10 or lighting device 20 by interacting with, selecting, pressing, and/or the like an on/off or power button, switch, and/or the like. For example, the user may interact with, select, press, and/or the like the on/off and/or dimmer switch 42 on the remote switch 40, the remote switch 40 may provide an on/off signal to the switch control unit 35, and the switch control unit 35 may cause the LED lamp 10 or LED lighting device 20 to turn on.
At block 214, the light aspects or qualities (e.g., color temperature, brightness, CRI, and/or the like) that the LED lamp 10 or LED lighting device 20 are to be operated at may be identified. For example, the color temperature the LED lamp 10 or LED lighting device 20 was last operated at may be identified. In another example, the memory element 36 may be accessed (e.g., by the processing element 37) to identify the appropriate operating light aspects or qualities based on the programmed custom operating mode, the time of day, and/or the like. If the LED lamp 10 or LED lighting device 20 is in a programmable custom operating mode in which a custom operating color temperature has been programmed, the switch control unit 35 may determine the appropriate combination of LED packages 18 to be activated to provide light of the custom operating color temperature and the corresponding provider circuits 17 that are to be activated, the current at which the provider corresponding provider circuits 17 are to be activated with, and/or the like.
At block 216, the LED lamp 10 or LED lighting device 20 is operated at the identified operating light aspects or qualities. For example, the switch control unit 35 may cause the driver circuitry 19 to operate the LED lamp 10 or LED lighting device 20 at the operating light aspects or qualities. For example, the driver circuitry 19 may operate at least one of the two or more LED packages 18 to cause the LED lamp 10 or LED lighting device 20 to emit light at the identified operating color temperature. For example, the appropriate provider circuits for providing the identified operating color temperature are activated such that the LED lamp 10 or LED lighting device 20 provides light of the user-selected operating color temperature. For example, the driver circuitry 19 may drive one or more LED packages 18 to provide light having the identified light aspects or qualities.
At block 218, it is determined if a light aspect or quality change signal is received. If a light aspect or quality change signal has not been received (e.g., as determined by the switch control unit 35), the process returns to block 216. If a light aspect or quality change signal is received, the process continues to step 220, wherein it is determined if the LED lamp 10 or LED lighting device 20 is in a set operating mode. In some embodiments, the programmable custom operating mode may be a set mode, wherein the operating color temperature (and/or other light aspects or qualities) of the LED lamp 10 or LED lighting device 20 cannot be modified during operation of the LED lamp 10 or LED lighting device 20. In some example embodiments, the programmable custom operating mode may be a selectively configurable mode, wherein the operating color temperature (or other light aspect or quality) of the LED lamp 10 or LED lighting device 20 may be modified during operation of the LED lamp 10 or LED lighting device 20. For example, the operating color temperature of the LED lamp 10 or LED lighting device 20 may be switched between one or more predefined color temperatures (e.g., the first, second, and third color temperatures) and the programmed custom operating color temperature (and/or brightness and/or CRI and/or the like). Thus, the switch control unit 35 may determine (e.g., based on the status of the switch 30 and/or one or more programs and/or the like stored by the memory element 36) if the LED lamp 10 or LED lighting device 20 is in a set mode or a configurable mode.
If it is determined that the LED lamp 10 or LED lighting device 20 is in a set mode, the process returns to block 216, and the LED lamp 10 or LED lighting device 20 continues to provide light at the operating light aspects or qualities. If it is determined that the LED lamp 10 or LED lighting device 20 is in a configurable mode, the process continues to block 222. At block 222, the operating light aspects or qualities are modified in accordance with the received light aspect or quality change signal. The process then returns to block 216.
