Abstract

A light fixture is disclosed herein. The light fixture can include a power supply and at least one light source coupled to the power supply. The light fixture can also include a local controller coupled to the power supply, where the local controller sends at least one first signal to the power supply to control the power supply, where controlling the power supply controls a light output of the at least one light source.

Claims

1. A light fixture, comprising:

a power supply;

at least one light source coupled to the power supply; and

a local controller coupled to the power supply, wherein the local controller sends at least one first signal to the power supply to control the power supply, wherein controlling the power supply controls a light output of the at least one light source, and wherein the local controller is independent of an external controller in a lighting system.

2. The light fixture of claim 1, wherein the local controller is configured to communicate with the external controller of the lighting system, wherein the local controller sends at least one second signal to the external controller based on the at least one first signal.

3. The light fixture of claim 2, wherein the additional device comprises at least one selected from a group consisting of an additional light fixture, a heating/ventilation/air conditioning unit, an electrical receptacle, a shade control device, and a wall switch.

4. The light fixture of claim 1, wherein the at least one first signal is based on default settings.

5. The light fixture of claim 1, further comprising:

at least one sensor coupled to the local controller, wherein the at least one sensor measures at least one parameter, wherein the at least one first signal is based, in part, on the at least one parameter measured by the at least one sensor.

6. The light fixture of claim 5, wherein the local controller is configured to send at least one second signal to the external controller, wherein the at least one second signal is based on the at least one parameter measured by the at least one sensor.

7. The light fixture of claim 1, wherein the local controller controls the power supply on a continuous basis.

8. The light fixture of claim 1, wherein the at least one first signal is based, in part, on a demand response signal received by the local controller from a user.

9. A lighting system comprising:

a first light fixture comprising;

a first power supply;

at least one first light source coupled to the first power supply; and

a first local controller coupled to the first power supply, wherein the first local controller sends at least one first signal to the first power supply to control the first power supply, wherein controlling the first power supply controls a first light output of the at least one first light source, and wherein the first local controller is independent of an external controller in the lighting system.

10. The lighting system of claim 9, wherein the first light fixture further comprises at least one first sensor coupled to the first local controller, wherein the at least one first sensor measures at least one first parameter, wherein the at least one first signal is based, in part, in the at least one first parameter measured by the at least one first sensor.

11. The lighting system of claim 9, further comprising:

an electrical device coupled to the first local controller, wherein the electrical device receives at least one second signal from the first local controller, wherein the at least one second signal controls the electrical device.

12. The lighting system of claim 11, wherein the electrical device is an electrical receptacle, and wherein the at least one second signal prevents power from flowing to an outlet of the electrical receptacle.

13. The lighting system of claim 9, further comprising:

a second light fixture device coupled to the first controller, wherein the second light fixture comprises;

a second power supply;

at least one second light source coupled to the second power supply; and

a second local controller coupled to the second power supply, wherein the second local controller sends at least one second signal to the second power supply to control the second power supply, wherein controlling the second power supply controls a second light output of the at least one second light source, and wherein the second local controller is independent of the external controller in the lighting system.

14. The lighting system of claim 13, wherein the second local controller further sends the at least one second signal to the first local controller.

15. The lighting system of claim 13, wherein the second local controller receives the at least one first signal sent by the first local controller.

16. The lighting system of claim 15, wherein the at least one first signal is used by the second local controller to generate the at least one second signal.

17. The lighting system of claim 13, wherein the second light fixture further comprises at least one second sensor coupled to the second controller, wherein the at least one second sensor measures at least one second parameter, wherein the at least one second signal is based, in part, in the at least one second parameter measured by the at least one second sensor.

18. A local controller integrated with a light fixture, the controller comprising:

a hardware processor;

memory comprising a plurality of software instructions, wherein the plurality of software instructions are executed by the hardware processor; and

a control engine coupled to the hardware processor and a power supply of the light fixture, wherein the control engine sends at least one signal to the power supply to control the power supply, wherein controlling the power supply controls a light output of at least one light source of the light fixture.

19. The local controller of claim 18, further comprising:

a transceiver coupled to the control engine, wherein the transceiver is configured to transfer at least one second signal with a user.

20. The local controller of claim 19, wherein the at least one second signal is sent by the user to alter a setting of the control engine.
