Abstract

A luminaire includes a light emitting diode module, a driver housing, and a hollow connector that connects the driver housing and the light emitting diode module. The driver housing includes a rotatable cap and a driver that provides power to the light emitting diode module. The rotatable cap permits rotation of the hollow connector and the light emitting diode module in order to direct the light from the light emitting diode module in a desired direction. The light emitting diode module includes a plurality of optics wherein each optic covers at least one light emitting diode and at least one vent adjacent to each optic.

First claim

What is claimed is:

1. A luminaire comprising:
a light emitting diode (LED) module comprising:
a plurality of optics, each optic of the plurality of optics covering one or more LEDs, and each optic of the plurality of optics located adjacent to at least one vent that passes through the LED module;
an LED plate on which the plurality of optics and the one or more LEDs are mounted; and
an LED module casting, the LED module casting comprising mounting pads and wiring cavities;

a driver housing comprising a driver and a rotatable cap for rotating the LED module; and
a hollow connector that connects the LED module and the rotatable cap of the driver housing.

2. The luminaire of claim 1 , wherein the driver housing further comprises a side aperture for receiving a pole for mounting the luminaire above a roadway.

3. The luminaire of claim 1 , wherein the rotatable cap comprises a first set of apertures for receiving a plurality of fasteners that pass through the rotatable cap and fasten to the hollow connector.

4. The luminaire of claim 3 , wherein the rotatable cap comprises a second set of apertures for receiving rotational set screws for fastening the rotatable cap to the driver housing after the plurality of fasteners are fastened, the rotational set screws preventing rotation of the rotatable cap.

5. The luminaire of claim 1 , wherein the rotatable cap comprises at least one third aperture for receiving a tamper-proof security screw that attaches the rotatable cap to the hollow connector.

6. The luminaire of claim 1 , wherein the rotatable cap comprises at least one fourth aperture for receiving a wiring grommet through which one or more wires can pass for connecting to the driver.

7. The luminaire of claim 1 , wherein the rotatable cap can rotate up to 180 degrees in one direction and up to 179 degrees in the opposite direction.

8. The luminaire of claim 1 , wherein the driver housing comprises at least one wall having a flat interior surface against which the driver can be placed.

9. The luminaire of claim 8 , wherein the at least one wall of the driver housing further comprises heat sink fins disposed on an exterior surface of the at least one wall.

10. The luminaire of claim 1 , wherein the LED module comprises a plurality of heat sink fins wherein at least one heat sink fin of the plurality of heat sink fins is disposed over each vent.

11. The luminaire of claim 10 , wherein the plurality of heat sink fins are oriented in different directions.

12. The luminaire of claim 1 , wherein the one or more LEDs are aligned with the mounting pads.

13. The luminaire of claim 1 , wherein the wiring cavities comprise wiring for connecting the one or more LEDs to the driver.

14. A luminaire comprising:
a driver housing comprising a driver, a rotatable cap, and a mounting assembly;
a light emitting diode (LED) module comprising a plurality of optics, each optic of the plurality of optics covering one or more LEDs; and
a hollow connector that connects the LED module and the driver housing, the hollow connector and the LED module rotatable by the rotatable cap,
wherein the LED module further comprises wiring cavities for receiving wiring that connects the one or more LEDs with the driver via the hollow connector.

15. The luminaire of claim 14 , wherein the plurality of optics are biased to emit light from the one or more LEDs in a designated direction.

16. The luminaire of claim 14 , wherein the LED module further comprises at least one vent adjacent to each optic of the plurality of optics, each vent traversed by at least one heat sink fin.

17. The luminaire of claim 14 , wherein the mounting assembly of the driver housing comprises at least one clamp for securing a mounting post.

18. The luminaire of claim 14 , wherein the rotatable cap comprises a plurality of apertures for receiving a plurality of fasteners that fasten the rotatable cap to the hollow connector.

19. The luminaire of claim 14 , wherein the LED module further comprises a rim along a perimeter of the LED module.

20. The luminaire of claim 14 , wherein each optic of the plurality of optics is asymmetric.

21. The luminaire of claim 14 , wherein the LED module further comprises a plurality of mounting pads, wherein each LED of the one or more LEDs is aligned with a mounting pad of the plurality of mounting pads.

22. The luminaire of claim 14 , wherein the LED module further comprises an LED plate on which the plurality of optics are mounted.

23. The luminaire of claim 22 , wherein the LED module further comprises an LED module casting to which the LED plate is attached.

24. The luminaire of claim 23 , wherein the LED module further comprises a plurality of heat sink fins that dissipate heat from the LED module casting.

25. The luminaire of claim 14 , further comprising a shroud that covers the hollow connector.
