Toggle control for lighting system
View Patent ↗Lighting systems and methods implementing toggle control are provided. In one example implementation, a lighting system includes a first LED array having one or more LED devices and a second LED array having one or more LED devices. The system further includes a single throw circuit interrupter configured to receive power from a power source. The system further includes a power conversion circuit configured to convert an input power received via the toggle switch to a power output for the first LED array and the second LED array. The power conversion circuit is configured to control a power distribution ratio between the first LED array and the second LED array based at least in part on a detected toggle input (e.g., a toggle pattern) implemented using the single throw circuit interrupter.
1. A lighting fixture, comprising:
a first LED array associated with a first color temperature;
a second LED array associated with a second color temperature; and
a circuit including a controller configured to determine a ratio of current provided to the first LED array relative to the second LED array to adjust a color temperature of a combined light output of the first LED array and the second LED array based, at least in part, on a detected toggle input.
2. The lighting fixture of claim 1 , wherein the circuit is configured to adjust the color temperature of the combined light output to correspond to a color temperature of about 3000 Kelvin.
3. The lighting fixture of claim 1 , wherein the circuit is configured to adjust the color temperature of the combined light output to correspond to a color temperature of about 4000 Kelvin.
4. The lighting fixture of claim 1 , wherein the circuit is configured to adjust the color temperature of the combined light output to correspond to a color temperature of about 5000 Kelvin.
5. The lighting fixture of claim 1 , wherein the circuit is further configured to convert an input power to an output power for the first LED array and the second LED array.
6. The lighting fixture of claim 1 , wherein the circuit is configured to adjust a power distribution amongst the first LED array and the second LED array such that the first LED array receives 100 percent of the output power and the second LED array receives 0 percent of the output power.
7. The lighting fixture of claim 1 , wherein the circuit is configured to adjust a power distribution amongst the first LED array and the second LED array such that the first LED array receives 0 percent of the output power and the second LED array receives 100 percent of the output power.
8. The lighting fixture of claim 1 , wherein the circuit is configured to adjust a power distribution amongst the first LED array and the second LED array such that the output power is split between the first LED array and the second LED array.
9. The lighting fixture of claim 1 , wherein the circuit is configured to sweep a power distribution amongst the first LED array and the second LED array to adjust the color temperature of the combined light output.
10. The lighting fixture of claim 1 , wherein the circuit is configured to adjust the color temperature of the combined light output by the lighting fixture from a color temperature of about 3000K to a color temperature of about 4000K.
11. The lighting fixture of claim 1 , wherein the circuit is configured to adjust the color temperature of the combined light output by the lighting fixture from a color temperature of about 4000K to a color temperature of about 5000K.
12. The lighting fixture of claim 1 , wherein the circuit further comprises a toggle control circuit configured to detect the toggle input and to provide one or more control signals to a distribution circuit based at least in part on the toggle input to adjust the color temperature of the combined light output.
13. The lighting fixture of claim 1 , wherein the toggle input comprises a plurality of successive toggles within a time period.
14. The lighting fixture of claim 1 , wherein the toggle input is implemented using a single throw circuit interrupter.
15. The lighting fixture of claim 14 , wherein the single throw circuit interrupter comprises a toggle switch.
16. A method for controlling a lighting fixture comprising a first LED array associated with a first color temperature and a second LED array associated with a second color temperature, the method comprising:
detecting a toggle input; and
responsive to detecting the toggle input, determining a ratio of current provided to the first LED array relative to the second LED array and adjusting a color temperature of a combined light output of the first LED array and the second LED array based on the ratio.
17. The method of claim 16 , wherein adjusting the color temperature of the combined light output comprises: adjusting the color temperature of the combined light output from a color temperature of about 3000 Kelvin to a color temperature of about 4000 Kelvin.
18. The method of claim 16 , wherein adjusting the color temperature of the combined light output comprises: adjusting the color temperature of the combined light output from a color temperature of about 4000 Kelvin to a color temperature of about 5000 Kelvin.
19. The method of claim 16 , further comprising sweeping a power distribution amongst the first LED array and the second LED array to adjust the color temperature of the combined light output.
