Embodiments herein relate to solid-state lighting circuits.
The term solid-state lighting (SSL) refers to a type of lighting in which light is emitted from a semiconductor, rather than from an electrical filament (as in the case of traditional incandescent light bulbs), a plasma (as is in the case of arc lamps such as fluorescent lamps) or a gas. Examples of SSL emitters include light-emitting diodes (LEDs), organic light-emitting diodes (OLEDs) or polymer light-emitting diodes (PLEDs) as sources of illumination rather than electrical filaments, plasma (e.g., used in arc lamps such as fluorescent lamps) or gas. Compared to incandescent lighting, SSL creates visible light with reduced heat generation or parasitic energy dissipation. In addition, its solid-state nature provides for greater resistance to shock, vibration and wear, thereby increasing its lifespan significantly.
In an embodiment, a solid-state lighting circuit is included. The circuit can include a first plurality of emitters configured to output light of a first color and a second plurality of emitters configured to output light of a second color. The first plurality of emitters and the second plurality of emitters can be configured to be operably connected to a constant current power supply. The circuit can include a current limiting circuit and at least one biasing resistor operably connected to the first plurality of emitters and the current limiting circuit. The current limiting circuit can be configured to operably connect the constant current power supply to the first plurality of emitters. Current can be biased toward the first plurality of emitters until a preselected current limit is reached for the first plurality of emitters, such that the first plurality of emitters outputs the light of the first color. When current is provided by the constant current power supply that is at or above the preselected current limit, current can pass through the second plurality of emitters such that the second plurality of emitters outputs the light of the second color.
In an embodiment, a solid-state lighting circuit is included. The circuit can include a power supply path and a power return path. The circuit can include a first emitter branch comprising a current limiting circuit operably connected to a first plurality of emitters in series and at least one resistor, the first plurality of emitters configured to output light of a first color. The circuit can include a second emitter branch comprising a second plurality of emitters in series, the second plurality of emitters configured to output light of a second color. The first emitter branch can be operably connected to the power supply path and the power return path. The second emitter branch can be operably connected to the power supply path and the power return path in parallel with the first emitter branch. Current provided by the power supply path can be biased toward the first emitter branch until a preselected current limit is reached for the first plurality of emitters, such that the first plurality of emitters outputs the light of the first color. When current is provided by the power supply path that is at or above the preselected current limit, current can pass through the second emitter branch such that the second plurality of emitters outputs the light of the second color.
In an embodiment, a solid-state lighting device is included. The device can includea circuit board and a solid-state lighting circuit disposed on the circuit board. The solid-state lighting circuit can include a first plurality of emitters configured to output light of a first color and a second plurality of emitters configured to output light of a second color. The first plurality of emitters and the second plurality of emitters can be configured to be operably connected to a constant current power supply. The circuit can include a current limiting circuit and at least one biasing resistor operably connected to the first plurality of emitters and the current limiting circuit. The current limiting circuit can be configured to operably connect the constant current power supply to the first plurality of emitters. Current can be biased toward the first plurality of emitters until a preselected current limit is reached for the first plurality of emitters, such that the first plurality of emitters outputs the light of the first color. When current is provided by the constant current power supply that is at or above the preselected current limit, current can pass through the second plurality of emitters such that the second plurality of emitters outputs the light of the second color.
In an embodiment, a method for changing the net color output of a solid-state lighting device is included. The method can include receiving an input current and emitting light of a first color from a first plurality of emitters in response to the input current, the first plurality of emitters operably connected to a current limiting circuit and at least one biasing resistor that provides a preselected current limit for the first plurality of emitters. The method can further include biasing the input current toward the first plurality of emitters until the preselected current limit is reached, such that the first plurality of emitters outputs the light of the first color. The method can further include emitting light of a second color from a second plurality of emitters in response to the input current when the preselected current limit for the first plurality of emitters is met or exceeded, the second color being different than the first color.
This summary is an overview of some of the teachings of the present application and is not intended to be an exclusive or exhaustive treatment of the present subject matter. Further details are found in the detailed description and appended claims. Other aspects will be apparent to persons skilled in the art upon reading and understanding the following detailed description and viewing the drawings that form a part thereof, each of which is not to be taken in a limiting sense. The scope herein is defined by the appended claims and their legal equivalents.
Aspects may be more completely understood in connection with the following figures (FIGS.), in which:
While embodiments are susceptible to various modifications and alternative forms, specifics thereof have been shown by way of example and drawings, and will be described in detail. It should be understood, however, that the scope herein is not limited to the particular aspects described. On the contrary, the intention is to cover modifications, equivalents, and alternatives falling within the spirit and scope herein.
The present disclosure is generally related to solid-state lighting (SSL) circuits, devices including the same, and related methods. Examples of SSL devices herein include, but are not limited to, lighting fixtures, light bulbs, lighting strips, and/or components thereof. According to various embodiments, SSL lighting devices are provided that contain one or more SSL emitters. Generally speaking, the SSL emitters produce light when provided with electrical power meeting certain voltage and current characteristics. According to various embodiments, SSL emitters herein specifically include light emitting diodes (LEDs). However, other types of SSL emitters can also be used. Accordingly, while various embodiments are described herein as using LEDs, it will be appreciated that other types of SSL emitters may be used instead of, or in addition to, LEDs in various implementations.
According to various embodiments, a lighting device with multiple LEDs (or other SSL emitters) can be controlled with a constant current power supply (and in various embodiments a single constant current power supply). As the supply current from the constant current power supply increases, light from the lighting device changes from a first color with increasing brightness to a blended combination of the first color and a second color. In some embodiments, as the supply current is further increased, the light changes to a blended combination of the first and second colors in which the second color increases in brightness, thereby dominating the first color.
In various embodiments, an LED lighting device includes a first group of LEDs (one or more) and a second group of LEDs (one or more). The lighting device includes a current limiting circuit and one or more biasing resistors configured so that current provided by a constant current power supply is preferred by the first group of LEDs until a current limit for the first group of LEDs is met. The second group of LEDs starts to take available supply current around the time that the current limit is met. According to various embodiments, the second group of LEDs begins to take available supply current based on a voltage stack of the first group of LEDs along with the biasing resistors with the current limiting circuit. When the first group of LEDs reaches a maximum set current limit, the second group of LEDs takes all remaining increases in the supply current, thus making the second group of LEDs brighter than the first group of LEDs.
According to various embodiments, the first group of LEDs is configured to output light of a first color and the second group of LEDs is configured to output light of a second color (for example, a different color temperature). With the first and second groups of LEDs initially off, increasing a controlled supply current (for example, with a dimming control on the power supply) causes the first group of LEDs of the first color to turn on and then increase in brightness toward a maximum brightness. As the supply current increases further, the second group of LEDs of the second color begins to onset. In some cases, the first color may or may not continue to increase in brightness after the second group of LEDs turns on. As the supply current is further raised, the second color increases in brightness while the first color continues at a maximum brightness. Thus, according to various embodiments, the LEDs emit a first color that gives way to a brighter combined blending of the first and second colors.
Various embodiments incorporate advantageous techniques for powering and operating one or more LEDs (or other SSL emitters). In some cases such techniques can result in lower costs for operating the LEDs. In some cases LEDs can be powered and operated with a driving circuit that is simpler than known driving circuits, having, for example, fewer active components and/or fewer components in general. According to various implementations, powering and/or operating one or more LEDs on a lighting device includes a dimming capability. As an example, various embodiments provide a lighting device with multiple LEDs. The brightness of different LEDs can be adjusted at different times using a single power supply. In various implementations, a single control, such as, for example, a single dimmer switch can be used to dim or brighten an LED lighting device by turning multiple LEDs on (or off) at different times. According to various embodiments, a single control can be used to change the color of the light from an LED lighting device. In some cases a single control (e.g., a single dimmable power supply) is used to transition the color as well as the brightness of the light generated by an LED lighting device.
As previously discussed, various embodiments are directed to solid-state lighting (SSL) devices that include one or more SSL emitters. Referring now to
In various embodiments, the circuit 100 includes two or more emitter branches connected between the power supply and return paths. As depicted in
As shown in
According to various embodiments, the SSL circuit 100 includes at least two biasing resistors for adjusting relative voltage levels in the circuit. In various implementations, the feedback resistor 130 functions as a first biasing resistor.
According to various implementations, the SSL circuit 100 is configured to be powered by a constant current power supply connected to the pads 102, 104. The power supply can be adjusted using a dimming control such as, for example, a dimming switch. Actuating the dimming control adjusts the level of current supplied to the SSL circuit 100 by the constant current power supply.
According to various embodiments the first group 110 of emitters produces a first color of light and the second group 140 of emitters produces a second color of light that is different from the first color. As an example, in various implementations the first color is a warm white color and the second color is a white color. As discussed herein, assigning a different color temperature to each group of emitters can in various embodiments provide the circuit 100 with the ability to change light output in terms of both brightness and color temperature. According to various embodiments, the SSL circuit 100 changes the overall light output and/or combined visual impression of the circuit's light output by changing which of the emitter groups is active and/or by changing the intensity or brightness of the light generated by one or both of the first and second emitter groups 110, 140.
Operation of the solid-state lighting circuit 100 according to various embodiments will now be described, with additional reference to
According to various embodiments, the SSL circuit 100 operates to direct current flow from a constant current power supply (e.g., via the power supply path 106) to one or both of the first and second groups 110, 140 of emitters. In various implementations, a preselected current limit 214 is set for the first group 110 of emitters by the current limiting circuit and the biasing resistors, including the voltage regulator 120, the feedback resistor 130, and the bleed resistor 160 (in some embodiment 10K or greater ohms). Many different preselected current limits 214 can be used depending on the current and wattage of the emitters used. By way of example, exemplary current limits using 0.5 and 1 watt emitters can include about 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, or 125 mA, or an amount that falls within a range between any of the foregoing.
As current is received at the power supply path 106 from the constant current power source, the current is biased toward the first group of emitters until the preselected current limit is reached. As shown in
According to various embodiments, the second group 140 of emitters remains off at current levels below the preselected current limit 214, thus allowing the combined light output 220 shown in
According to various implementations, such as the one illustrated in
In various cases the SSL devices can include two or more SSL circuits 100 in series. In some embodiments, an SSL device herein can include 10, 20, 30, 50, 100, 200, 500 or more SSL circuits 100 in series. Referring now to
As discussed herein, in various embodiments, the SSL circuit 100 shown in

In some embodiments, two pads are provided for connecting a power supply. In various embodiments, the first pad 432 is configured to operably connect to and receive a supply signal from the power supply and pass the supply onto a power supply path. In some cases the supply signal may be a DC voltage or current. In some cases the supply signal may be an AC voltage or current that is then rectified to provide a positive signal for the circuit board 400. According to various embodiments, the power supply is a constant current power supply that supplies the first pad 432 with a regulated, constant current supply. The second pad 434 is the return path for the power supply. Additional pads 436 may be used for control signal input or output in various embodiments. While
Referring now to
The SSL device 500 also includes a transient voltage suppression (TVS) device 520 that is operably connected to the power pads to prevent damage from high voltage transients from the power supply. One example of a TVS device is a Fairchild Semiconductor SMBJ36CA TVS diode, however, many other TVS devices are contemplated herein. In addition, a current limiting circuit including a regulator 522 and a feedback resistor 524 is provided, along with a biasing resistor 526 and multiple ballast resistors 528. As previously discussed, in various embodiments the current limiting circuit and biasing resistor(s) can be used to set a preselected current limit for one group of emitters.
Additional pads 516 can be used in some cases to operably connect the SSL device 500 to another circuit or assembly. According to various embodiments, another SSL device (e.g., an identical SSL device 500 or another) can be operably connected to the SSL device 500 using the additional pads 516. As an example, two SSL devices, each incorporating an SSL circuit 100 as shown in
According to some embodiments, many types of consumer, commercial, and industrial products can incorporate solid-state lighting devices in various configurations to provide illumination. Examples of products that can include SSL devices according to various embodiments include, but are not limited to, light bulbs, lamps, lanterns, flashlights, decorative lighting, commercial lighting fixtures, displays, and other products of various sizes, configurations and uses. Referring now to
In various implementations, one or more of the SSL devices 610 incorporate the solid-state lighting circuit 100 shown and described with respect to
As discussed herein, various embodiments are operably configured to be powered by a constant current power supply. In some cases a solid-state lighting device can be enabled to operate using a DC power supply. In some cases a SSL device can be enabled to operate using an AC power supply. Referring now to
In various embodiments, the SSL device 710 or another part of the system 700 includes a full-wave or half-wave rectifier that rectifies the AC power signal before it reaches the SSL emitters on the solid-state lighting device 710. In various embodiments a DC power source may be used to power the SSL device 710, in which case the rectifier and likely the transformer 716 would not be needed.
Referring now to
According to some embodiments, in the event that the primary power source 814 is unavailable, the SSL circuit 810 will turn on a first group of emitters that generate a first color of light using backup power stored in the battery 820. In some cases the circuit 810 will also turn on a second group of emitters that output a second color of light if the supply from the backup power source 820 enables a constant current from the power supply 830 that exceeds a preselected threshold current for the first group of emitters.
Methods
Various methods are included herein. For example, methods herein can include a method of manufacturing an SSL device, a method of changing the net output and/or color output of a solid-state lighting device, and the like. Referring now to
In various embodiments the method also includes increasing the brightness of the light of the first color as the input current increases up to a preselected current limit. After the preselected current limit is reached, the method can also include maintaining a maximum brightness of the light of the first color as the input current increases above the preselected current limit, according to some implementations. In some cases the method includes increasing a brightness of the light of the second color as the input current increases, after the preselected current limit is reached.
Emitters
As described herein, embodiments incorporate the use of one or more solid-state lighting (SSL) emitters. According to various embodiments, SSL emitters are implemented as light emitting diodes (LEDs). Other types of SSL emitters may also be used. Accordingly, while various embodiments are described herein as using LEDs, it will be appreciated that other types of SSL emitters may be used instead of, or in addition to, LEDs in various implementations.
As shown in
According to some embodiments, as the constant current fed to the first and second groups of emitters is increased, the color mix of the turned on emitters can change. In some cases specific emitters of varying colors can be positioned in emitter strings so the controlled sequence would turn on emitters so to precisely control color mixes above and below the preselected current limit. This is extremely beneficial in applications where it is desirable to cast a warm (reddish) light color as the lights begin to come on, transitioning to a cooler brighter (bluish) light at full intensity. It is also beneficial when special lighting effects, such as the transition of a primary light color to blended light color is desired (example: green plus red produces yellow).
With continuing reference to
According to some embodiments the light produced by each individual emitter within the first and second groups is nominally the same color temperature as the other emitters with each respective group. In some embodiments each of the emitters within a particular group may be rated by the manufacturer as having a distinct and different color temperature, but may still be considered as being within an acceptable temperature range such that the combined light generated by a particular group of LEDs has a desired appearance. In some embodiments, emitters having a color temperature within a specific flux bin can be selected for each of the emitters of an SSL device individually. As one possible example, in some cases a first group of three LEDs can generally provide a warm white light but individually have separate color temperatures, such as 2000K, 2700K, and 3000K according to specific flux bins provided by the manufacturer. In a similar manner, a second group of three LEDs can output a white color of light, but individually may have separate color temperatures, such as, for example, 4000K, 4500K, and 5000K. Of course other color temperatures and mixtures of emitters have various color temperatures can be provided in various embodiments depending upon the desired characteristics of the light to be generated by the emitters.
Other Components
As described herein, various embodiments provide a current limiting circuit that includes a voltage regulator with a feedback resistor placed across the regulator's output and adjustment pins in order to provide a regulated constant current to the first group of emitters. See
According to various embodiments, a solid-state lighting circuit is operably connected to a dimmable constant current power source.
