Abstract

The present disclosure relates generally to an integrated signal light head. In one embodiment, the integrated signal light head includes a molded housing for holding at least one light emitting diode (LED) light source and a power supply compartment coupled to the molded housing. As a result, a power supply may be remotely located and independent of the at least one LED light source.

Claims

1. An integrated signal light head, comprising:

a molded housing for holding at least one light emitting diode (LED) light source; and

a power supply compartment coupled to the molded housing.

2. The integrated signal light head of claim 1, wherein the at least one LED light source is located on an inside portion of the molded housing and an outside portion of the molded housing directly opposite the at least one signal light is exposed to outside air.

3. The integrated signal light head of claim 1, wherein the power supply compartment is located remotely from the at least one LED light source.

4. The integrated signal light head of claim 1, wherein the power supply compartment includes at least one power supply that is plug-and-play.

5. The integrated signal light head of claim 1, wherein the at least one power supply is replaceable independent of the at least one LED light source.

6. The integrated signal light head of claim 1, wherein the at least one LED light source comprises a plurality of LED light source and wherein the power supply compartment includes a single power supply that powers each one of the plurality of LED light sources.

7. The integrated signal light head of claim 1, wherein the at least one LED light source comprises a plurality of LED light source and wherein the power supply compartment includes a power supply for each one of the plurality of LED light sources.

8. The integrated signal light head of claim 1, wherein the molded housing and the power supply compartment are molded as a single piece.

9. An integrated traffic signal light head, comprising:

a molded housing for holding at least one light emitting diode (LED) based traffic signal light, wherein the at least one LED based traffic signal light is powered by a remotely located power supply; and

a power supply compartment coupled to the molded housing.

10. The integrated traffic signal light head of claim 9, wherein the at least one signal light comprises a red colored LED, a yellow colored LED and a green colored LED.

11. The integrated traffic signal light head of claim 9, wherein the power supply compartment is located remotely from the at least one LED.

12. The integrated traffic signal light head of claim 9, wherein the power supply compartment includes the remotely located power supply.

13. The integrated traffic signal light head of claim 12, wherein the remotely located power supply is plug-and-play.

14. The integrated traffic signal light head of claim 12, wherein the at least one LED based traffic signal light comprises a plurality of LED based traffic signal lights and wherein the power supply compartment includes a single power supply that powers each one of the plurality of LED based traffic signal lights.

15. The integrated traffic signal light head of claim 12, wherein the at least one LED based traffic signal light comprises a plurality of LED based traffic signal lights and wherein the power supply compartment includes a power supply for each one of the plurality of LED based traffic signal lights.

16. The integrated traffic signal light head of claim 9, wherein the molded housing and the power supply compartment are molded as a single piece.

17. An integrated signal light head, comprising:

a molded housing for holding at least one light emitting diode (LED) based traffic signal light; and
