The present invention relates to the fields of lighting devices and, more specifically, to canister light fixtures and lighting devices that are rotatable and emit light in different beam angles and amounts, and associated methods.
The majority of lighting devices are fixed, meaning they cannot be adjusted to direct light emitted therefrom, thus changing the area illuminated. Of those lighting devices that can be adjusted, many require a user to manually move components of the lighting device to direct the lighting device, thus changing the area illuminated. There are some lighting fixtures that permit mechanized adjustment of the direction of the lighting device, but many of those mechanized devices are limited in their range of motion and often occupy large volumes. Accordingly, there is a long felt need for a lighting fixture that will matingly engage with existing fixtures and permits a wide range of motion to direct light while not occupying an inordinate volume of space.
Lighting technologies such as light-emitting diodes (LEDs) offer significant advantages over incandescent and fluorescent lamps. These advantages include, but are not limited to, better lighting quality, longer operating life, and lower energy consumption. The majority of LED lighting devices include LEDs that are configured together on a single plane or on a single board and emit light in one beam angle. There are some lighting devices that permit light to be emitted in more than one beam angle, but many of those devices are limited in the amount of light they emit. Accordingly, there is a long felt need for a lighting device that emits light in multiple beam angles and where the amount of light emitted is not as limited.
U.S. Pat. No. 8,172,436 to Coleman et al. discloses an LED lighting assembly that rotates by means of a pivot post and base system. The lighting assembly does not include more than one means of rotation, however, and it does not include LEDs on multiple planes which may allow light to be emitted in multiple beam angles and in various amounts. Furthermore, the lighting assembly does not have a base that allows it to matingly engage with a light fixture or socket.
U.S. Pat. No. 7,618,150 to Tseng-Lu Chien discloses an LED lighting device that includes an adjustable angle function and includes multiple LED units. This device allows light to be emitted at varied beam angles, but may not allow for an increase or a decrease in the amount of light emitted and may not be rotational about any axis or multiple axes.
This background information is provided to reveal information believed by the applicant to be of possible relevance to the present invention. No admission is necessarily intended, nor should be construed, that any of the preceding information constitutes prior art against the present invention.
In view of the foregoing, it is therefore an object of the present invention to provide an improved LED-based lamp for use in a space-limited lamp enclosure, such as a can light fixture, for example. The embodiments of the lighting device according to the present invention advantageously allow for emission of light in a number of directions or angles and with varied amounts of light. The lighting device according to an embodiment of the present invention also advantageously provides ease of installation.
With the above in mind, the present invention is directed to a lighting device that includes an outer body having a base, a medial portion, and an upper portion. The lighting device may also include an electronic device carrying assembly. The electronic device carrying assembly may include an assembly base that is carried by the medial portion of the outer body. The electronic device carrying assembly may also include an assembly top comprising a bottom portion, sidewalls, and a top portion. The bottom portion of the assembly top may include an assembly base connector member that pivotally engages a portion of the assembly base. The electronic device carrying assembly may further include a heat sink that matingly engages a portion of the assembly top, and a driver circuit.
The electronic device carrying assembly may be configured to rotate about a first rotational axis defined by a vertical axis of the lighting device that passes through a medial portion of the base of the outer body. The electronic device carrying assembly may further be configured to pivot about a second rotational axis defined by a horizontal axis passing through a medial portion of the assembly base connector member of the assembly top. Additionally, the first and second rotational axes may be about perpendicular to one another.
The lighting device according to an embodiment of the present invention also includes an electronic device carried by the electronic device carrying assembly and/or the outer body. The electronic device may, for example, be a light source. The light source may include a plurality of light emitting diodes configured to emit light that combines to form a white light. The light source may also be configured to emit light within a wavelength range corresponding to at least one of the ultraviolet spectrum, the infrared spectrum, and the visible spectrum.
In some embodiments of the present invention, the electronic device may include a first electronic device and a second electronic device. In such embodiments, the second electronic device may include a light source and may be carried by the outer body in a position generally towards the base relative to the first electronic device and/or the electronic device carrying assembly adjacent the first electronic device. A light channeling device may be configured to direct light emitted by the light source so as not to be incident upon the first electronic device. Furthermore, light generated from the light source may be directed to a lens by the light channeling device.
In other embodiments of the present invention, the first electronic device and the second electronic device may both include a light source. The light emitted by the first electronic device and the second electronic device may combine to form a combined light. The combined light may have a center beam and a gradient, and the center beam may have a greater brightness than the gradient.
Either or both of the amount of light and the type of light emitted by the second electronic device may be variable dependent upon either or both of the amount of light and the type of light emitted by the first electronic device. The amount of light and the type of light emitted by the first electronic device may be variable dependent upon either or both of the amount of light and the type of light emitted by the second electronic device.
The electronic device may include a communication device that is electrically coupled to the driver circuit. A rotation mechanism may be configured to rotate the electronic device carrying assembly about either or both of the first and second rotational axes. The communication device may be any one (or combination) of a wireless communication device, a radio device, a bluetooth device, a computer network device, a visible light communication device, a video device, a visual display device, and an acoustic device.
The lighting device according to an embodiment of the present invention may include a rotation mechanism. The rotation mechanism may include a first rotation mechanism configured to rotate the electronic device carrying assembly about the first rotational axis, and a second rotation mechanism configured to rotate the electronic device carrying assembly about the second rotational axis. The first and second rotation mechanisms may be selected from the group consisting of an AC motor, a DC motor, an electrostatic motor, a servo motor, a stepper motor, an actuator, a hydraulic motor, a pneumatic motor, an electromagnet, and a permanent magnet.

According to an embodiment of the present invention, as depicted, for example, in
The light source 121 (as well as the second light source 122, which is only present in an alternate embodiment of the invention, as illustrated, for example, in
The light source carrying assembly 120 may comprise an assembly base 123, an assembly top 124, and a heat sink 125. The assembly base 123 may be carried by the medial portion 114 of the outer body 110. The assembly top 124 may comprise a bottom portion 126, sidewalls 127, and a top portion 128. The bottom portion 126 may include an assembly base connector member 129 that pivotally or rotationally engages a portion of the assembly base 123. The lighting device 100 may include one or more heat sinks 125, and portions of the heat sink 125 may include fins. The light source 121 and the second light source 122 may emit light which may produce heat. The heat sink 125 may provide surface area to allow heat to travel away from the light source 121 and the second light source 122, thereby cooling the light source 121 and the second light source 122. Removing heat from the light source 121 and the second light source 122 may enhance the life of the light source 121, the second light source 122, and the lighting device 100 in general.
The heat sink 125 may be configured to extend substantially the length of the outer body and the fins may be configured to extend substantially the length of the heat sink 125. Those skilled in the art will appreciate that the present invention contemplates the use of fins that extend any distance and may project radially outward from the heat sink 125, and that the disclosed heat sink 125 that includes fins that extend substantially the length thereof is not meant to be limiting in any way. The fins may increase the surface area of the heat sink 125 and may permit thermal fluid flow between each fin, thereby enhancing the cooling capability of the heat sink 125. The plurality of ribs 118 may also allow additional thermal fluid flow between each rib 118, thereby enhancing the cooling capability of the heat sink 125. Additional details and information regarding the cooling function of heat sinks with respect to lighting devices are provided in U.S. Provisional Patent Application Ser. No. 61/715,075 titled Lighting Device with Integrally Molded Cooling System and Associated Methods filed on Oct. 17, 2012
The lens 130 may attach to the outer body 110, the upper portion 116, the assembly top 124, and/or the top portion 128. Specifically, the lens 130 may form an interference fit with the outer body 110, the upper portion 116, the assembly top 124, and/or the top portion 128. The interference fit preferably provides sufficient strength to carry the lens 130. Optionally, the lens 130 may be attached to the outer body 110, the upper portion 116, the assembly top 124, and/or the top portion 128 through the use of an adhesive, glue, or any other attachment method known in the art. As another further option, the lens 130 may include structural supports or other features to enhance stability of the lens and to enhance clarity and brightness of the light source 121.

The light source carrying assembly 120 may be further configured to pivot about a second rotational axis 162 defined by a horizontal axis passing through a centrally positioned portion of the assembly base connector member 129 of the assembly top 124. The second rotational axis 162 is perhaps best illustrated in
The first and second rotational axes 161, 162 may be perpendicular to one another. In noting, however, that the first and second rotational axes 161, 162 may be perpendicular to one another, those skilled in the art will appreciate that the first and second rotational axes 161, 162 may be substantially perpendicular to one another while still accomplishing the goals, features and objectives according to the present invention. The configuration of the first and second rotational axes 161, 162 allows for the lighting device 100 of the present invention to readily rotate and pivot so that light emitted from the light source 121 and the second light source 122 propagates substantially below a plane defined by a surface portion of the upper portion 116 of the outer body 110. More particularly, and by way of example, light emitted from the light source 121 and the second light source 122 may be emitted in a lower hemisphere, i.e., substantially below a plane formed by an end portion of the outer body 110. In the figures, the end portion of the outer body 110 is considered the annularly shaped portion adjacent the light source 121. Those skilled in the art will appreciate, however, that the light emitted by the light source 121 and the second light source 122 may be emitted below any plane as defined during construction of the lighting device 100 and in any direction due to the configuration of the first and second rotational axes 161, 162.
Although it is preferable for the light from the light source 121 and the second light source 122 to be emitted in a generally downward direction, i.e., in a direction opposite the base, those skilled in the art will appreciate that the light may shine outwardly from the light source carrying assembly 120 in an opposite direction through various openings, and also continue to emit through the openings formed in the outer body 110. This may advantageously allow for the lighting device 100 according to embodiments of the present invention to provide various lighting effects that may be desirable to a user.
In one embodiment of the invention, the assembly base 123 may be configured to rotate about the first rotational axis 161 resulting in the rotation of the light source carrying assembly 120. The assembly base connector member 129 may be configured to pivotally engage the assembly base 123 resulting in the pivoting of the light source carrying assembly 120.

The electronic device carrying assembly 120′ may be configured to pivot about a second rotational axis 162′ defined by a substantially horizontal axis passing through a medial portion of the assembly base connector member 129′ of the assembly top 124′. Additionally, in some embodiments, the first and second rotational axes 161′, 162′ may be substantially perpendicular to one another. Those skilled in the art will appreciate that there may be any number of locations where the first and second rotational axes 161′, 162′ may exist within the lighting device 100′ that will allow the lighting device 100′ to function as intended and the locations presented herein are only examples of possible locations.

The light source may comprise a light emitting diode (LED) or a plurality of light emitting diodes (LEDs) that may be configured to emit light that may combine to form a white light. The light source may also be configured to emit light within a wavelength range corresponding to the ultraviolet spectrum, the infrared spectrum, or the visible spectrum.
In the present embodiment, each of the assembly base 123′ and the assembly base connector member 129′ may be provided by a ball-and-socket joint as described hereinabove. This may provide 360 degrees of rotation of the electronic device carrying assembly 120′ about the first rotational axis 161′ and about 180 degrees of pivot of the electronic device carrying assembly 120′ about the second rotational axis 162′. This configuration advantageously allows for light emitted from the second light source 122′ to be readily directed as described above. Furthermore, where the electronic device 181′ is a light source, this configuration advantageously allows for light emitted from the light source 121′ to be readily directed as described above. Furthermore, where the electronic device 181′ is something other than a light source, this configuration advantageously allows for the repositioning and reorienting of the electronic device 181′ as may be desirable in its operation.
As an example, and without limitation,
The first light source 121′ may be carried by the electronic device carrying assembly 120′. The second light source 122′ may be carried by the outer body 110′. The amount of light or the type or characteristics of light emitted by the second light source 122′ may be variable dependent upon the amount of light and/or the type of light emitted by the first light source 121′ and the amount of light or the type of light emitted by the first light source 121′ may be variable dependent upon the amount of light and/or the type of light emitted by the second light source 122′. As an example, the variations of light intensity may include the first light source 121′ at minimum or maximum intensity combined with the second light source 122′ at minimum possible intensity or even off (no intensity) or maximum intensity and the combination may include any level of intensity between no intensity and a maximum combined intensity both across the visible spectrum and at narrow wavelength ranges therewithin, as well as the IR and UV spectrums, for the first and second light source 121′, 122′. The intensities of the first and second light source 121′, 122′ may also be reversed. As an additional example, the first light source 121′ may emit light within a wavelength range corresponding to the visible spectrum, whereas the second light source 122′ may emit light within a wavelength range corresponding to the ultraviolet spectrum or the infrared spectrum, or vice versa.

Light emitted by the first light source 121′ and/or the second light source 122′ may combine to form a combined light which may have specified characteristics. The combined light may have a center beam and a gradient, and the center beam may have a greater brightness than the gradient.
