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:

a first LED light source deployed in a first location in an indoor environment;

a second LED light source deployed in a second location, wherein the first location is different from the second location in an outdoor environment;

a first plug and play power supply for powering the first LED light source; and

a second plug and play power supply for powering the second LED light source, wherein the first plug and play power supply and the second plug and play power supply are located together in a power supply rack at a third location that is remotely located from the first LED light source and the second LED light source, wherein the first plug and play power supply and the second plug and play power supply are each designed to power the respective LED light source to minimize a power loss along a length of an electrical connection coupled to a respective LED light source and to provide a low voltage direct current (DC).

2. The LED lighting system of claim 1, wherein the first plug and play power supply and the second plug and play power supply operate at a constant current.

3. The LED lighting system of claim 1, wherein the first plug and play power supply is external to a first housing enclosing the first LED light source and the second plug and play power supply is external to a second housing enclosing the second LED light source.

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

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

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

a plurality of independently controlled LED light sources deployed in two different locations, wherein a first one of the two different locations comprises an indoor environment and a second one of the two different locations comprises an outdoor environment;

a plurality of plug and play power supplies, wherein each one of the plurality of plug and play power supplies is for powering one of the plurality of independently controlled LED light sources, wherein the plurality of plug and play power supplies is located together in a single power supply rack located remotely from the plurality of independently controlled LED light sources in a different location than the two different 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 plug and play power supplies and to provide a low voltage direct current (DC).

7. The LED lighting system of claim 6, wherein the different location comprises a ground level and the two different locations comprise a level higher than the ground level.

8. The LED lighting system of claim 6, wherein the different location comprises a ground level and the second one of the two different locations comprise a level lower than the ground level.

9. The LED lighting system of claim 6, wherein each one of the one or more plug and play power supplies is external to a housing of each one of the plurality of independently controlled LED light sources.
