Abstract

A lighting source that can be deployed in a hazardous environment is disclosed. For example, the lighting source comprises at least one light emitting diode and a power supply for providing power to the at least one light emitting diode. The lighting source also comprises an enclosure for housing the at least one light emitting diode and the power supply, where said lighting source is for deployment in a hazardous environment.

Claims (21)

1. A light source for signaling obstructions to aviation, comprising:

a transparent cover;

at least one light emitting diode;

a reflector, wherein the reflector directs a light emitted from the at least one light emitting diode;

a power supply for powering the at least one light emitting diode, wherein the power supply is encapsulated with a thermally conductive material;

a base plate coupled to the transparent cover, wherein the base plate and the transparent cover enclose the reflector and the at least one light emitting diode, wherein a gasket is disposed between the base plate and the transparent cover to form a seal, wherein the light source is deployed in a hazardous environment.

2. The light source of claim 1 , wherein the light source is a beacon.

3. The light source of claim 2 , wherein the beacon light comprises a metal base, wherein the metal base includes a means for mounting the beacon light to a structure.

4. The light source of claim 1 , wherein the at least one light emitting diode is mounted horizontally.

5. The light source of claim 1 , wherein the hazardous environment comprises flammable gases.

6. The light source of claim 1 , wherein the hazardous environment comprises flammable dust.

7. The light source of claim 1 , wherein the light source is mounted on a radio tower.

8. The light source of claim 1 , wherein the light source is mounted on a flare stack.

9. The light source of claim 1 , wherein the light source comprises a metal base.

10. The light source of claim 9 , wherein heat generated by the at least one light emitting diode is dissipated via the metal base.

11. The light source of claim 1 , wherein the power supply employs a thermistor for providing temperature compensation.

12. The light source of claim 1 , wherein the thermally conductive material comprises a silicon-based rubber.

13. The light source of claim 1 , wherein the at least one light emitting diode comprises a plurality of light emitting diodes in an array.

14. The light source of claim 13 , wherein the reflector comprises a plurality of arrays around the reflector.

15. The light source of claim 1 , wherein the power supply comprises a feedback via an over voltage sense circuit to detect an open circuit.

16. The light source of claim 15 , wherein the power supply limits an output voltage when the open circuit is detected.
