Abstract

The present disclosure is directed to a light emitting diode (LED) lighting system. In one embodiment, the LED lighting system includes an LED light source deployed in a first location and a power supply for powering the LED light source, wherein the power supply is remotely located from the LED light source in a second location and designed to power the LED light source to minimize a power loss along a length of an electrical connection coupled between the LED light source and the power supply.

Claims

1. A light emitting diode (LED) lighting system, comprising:

an LED light source deployed in a first location;

a power supply for powering the LED light source, wherein the power supply is remotely located from the LED light source in a second location and designed to power the LED light source to minimize a power loss along a length of an electrical connection coupled between the LED light source and the power supply.

2. The LED lighting system of claim 1, wherein the power supply comprises a plug and play module.

3. The LED lighting system of claim 1, wherein the power supply operates at a constant current.

4. The LED lighting system of claim 1, wherein the power supply comprises a direct current (DC) power source.

5. The LED lighting system of claim 1, comprising a plurality of LED light sources electrically connected to the power supply.

6. The LED lighting system of claim 1, wherein the power supply is external to a housing enclosing the LED light source.

7. The LED lighting system of claim 1, wherein the second location comprises a ground level and the first location comprises a level higher than the ground level.

8. The LED lighting system of claim 1, wherein the second location comprises a ground level and the first location comprises a level lower than the ground level.

9. A light emitting diode (LED) lighting system, comprising:

a plurality of independently controlled LED light sources deployed in one or more locations;

a plurality of power supplies, wherein each one of the plurality of power supplies is for powering one of the plurality of independently controlled LED light sources, wherein the plurality of power supplies is remotely located from the plurality of independently controlled LED light sources in a different location than the one or more locations and designed to power the plurality of independently controlled LED light sources to minimize a power loss along a length of an electrical connection coupled between a respective one of the independently controlled LED light sources and a corresponding one of the plurality of power supplies.

10. The LED lighting system of claim 9, wherein all of the plurality of power supplies are located together in a single power supply rack in the different location.

11. The LED lighting system of claim 10, wherein the different location comprises a ground level and the one or more locations comprises a level higher than the ground level.

12. The LED lighting system of claim 10, wherein the different location comprises a ground level and the one or more locations comprises a level lower than the ground level.

13. The LED lighting system of claim 9, wherein each one of the one or more power supplies is external to a housing of each one of the plurality of independently controlled LED light sources.

14. The LED lighting system of claim 9, wherein each one of the power supplies comprises a plug and play module.

15. The LED lighting system of claim 9, wherein each one of the power supplies comprises a direct current (DC) power source.

16. A distributed power network for a light emitting diode (LED) lighting system, comprising:

a power rack located on a ground level at a first location;

one or more power supplies coupled to the power rack via one or more respective electrical connections in the power rack; and

at least one LED light source located remotely from the power rack in a second location and coupled to the one or more respective electrical connections.

17. The distributed power network for the LED lighting system of claim 16, wherein the second location is located at a level higher than the ground level.

18. The distributed power network for the LED lighting system of claim 16, wherein the second location is located at a level lower than the ground level.

19. The distributed power network for the LED lighting system of claim 16, wherein each one of the one or more respective electrical connections comprises a plug and play connection.

20. The distributed power network for the LED lighting system of claim 17, wherein each one of the one or more power supplies operates at a constant current.
