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 a plurality of light emitting diode (LED) light sources, wherein the molded housing comprises a mating surface for mounting the integrated signal light head; and

a power supply compartment coupled to the molded housing, wherein said power supply compartment is located remotely from the plurality of LED light sources and comprises a door to access at least one power supply inside the power supply compartment without requiring removal of any of the plurality of LED light sources, wherein the molded housing and the power supply compartment are molded as a single piece.

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

3. The integrated signal light head of claim 1, wherein the at least one power supply is a plug-and-play power supply.

4. The integrated signal light head of claim 3, wherein the at least one power supply is replaceable independent of the plurality of LED light sources.

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

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

7. An integrated traffic signal light head, comprising:

a molded housing for holding a plurality of light emitting diode (LED) based traffic signal lights, wherein the plurality LED based traffic signal lights are powered by a remotely located power supply, wherein the molded housing comprises a mating surface for mounting the integrated traffic signal light head; and

a power supply compartment coupled to the molded housing, wherein said power supply compartment is located remotely from the plurality LED based traffic signal lights and comprises a door to access the remotely located power supply inside the power supply compartment without requiring removal of any of the plurality of LED based traffic signal lights, wherein the molded housing and the power supply compartment are molded as a single piece.

8. The integrated traffic signal light head of claim 7, wherein the plurality LED based traffic signal lights comprises a red colored LED, a yellow colored LED and a green colored LED.

9. The integrated traffic signal light head of claim 7, wherein the remotely located power supply is plug-and-play.

10. The integrated traffic signal light head of claim 7, wherein the remotely located power supply comprises a single power supply that powers each one of the plurality of LED based traffic signal lights.

11. The integrated traffic signal light head of claim 7, wherein the remotely located power supply comprises a power supply for each one of the plurality of LED based traffic signal lights.

12. An integrated signal light head, comprising:

a molded housing for holding a plurality of light emitting diode (LED) based traffic signal lights, wherein the molded housing comprises a mating surface for mounting the integrated signal light head; and

a power supply compartment coupled to the molded housing, wherein the power supply compartment includes at least one female plug for receiving a plug-and-play power supply, wherein said power supply compartment is located remotely from the plurality of LED based traffic signal lights and comprises a door to access the plug-and-play power supply inside the power supply compartment without requiring removal of any of the plurality of LED based traffic signal lights, wherein the molded housing and the power supply compartment are molded as a single piece.

13. The integrated signal light head of claim 12, wherein the plug-and-play power supply comprises a single power supply that powers each one of the plurality of LED based traffic signal lights.

14. The integrated traffic signal light head of claim 12, wherein the plug-and-play power supply comprises a power supply for each one of the plurality of LED based traffic signal lights.
