Abstract

The present disclosure is directed to wallpacks containing at least one light source, such as a light-emitting diode (LED). The wallpack light fixtures disclosed herein generally contain a housing, at least one light source, a power supply, and a plurality of heat sink fins.

First claim

The invention claimed is:

1. A wallpack light fixture, comprising:
a housing having a front, a back, and a height, the housing including adjacent upper and lower body portions each defining an internal volume, wherein the upper body portion is above the lower body portion along the height of the housing;
at least one light source mounted within the internal volume of the upper body portion;
a power supply disposed in the internal volume of the lower body portion; and
a plurality of heat sink fins on the back of the housing, wherein each of the heat sink fins extends continuously and heightwise from the lower body portion to the upper body portion.

2. The apparatus of claim 1 further comprising a pivotally attached door disposed on the second body portion.

3. The apparatus of claim 1 further comprising a raceway disposed between the first and second body portions to connect the power supply to the light source.

4. The apparatus of claim 1 further comprising a rear conduit entry extending from the exterior of a rear wall of the housing to the internal volume of the second body portion.

5. The apparatus of claim 1 further comprising a driver bracket mount coupled to the exterior face of the power supply, wherein the driver bracket mount is disposed within the internal volume of the second body portion.

6. The apparatus of claim 5 further comprising a terminal bracket mount, wherein the terminal bracket mount overlies the exterior face of the driver bracket mount.

7. The apparatus of claim 1 wherein the housing comprises a thermally conductive material comprising a polymer.

8. The apparatus of claim 1 wherein the heat sink fins are substantially continuous on the exterior rear of the housing.

9. The apparatus of claim 1 , wherein the lower body portion of the housing further comprises:
at least one side conduit entry; and
at least one side conduit mounting arm having a first end and a second end, wherein the first end is coupled to the at least one side conduit entry and wherein the second end terminates in a flat surface.

10. A wallpack light fixture comprising:
a housing having a front, a back, and a height, the housing including adjacent upper and lower body portions each defining an internal volume, wherein the upper body portion is above the lower body portion along the height of the housing;
at least one light source mounted within the internal volume of the upper body portion;
a power supply disposed in the internal volume of the lower body portion; and
a door pivotally attached to the lower body portion at a lower end of the lower body portion, whereby the door is pivotable downward and away from the lower body portion to access the internal volume of the lower body portion.

11. The apparatus of claim 10 wherein the pivotally attached door comprises a swinging mount with a flange capable of interlocking with a hinge bracket disposed on the housing.

12. The apparatus of claim 10 further comprising a grounding conductor electrically connecting the housing and the door.

13. The apparatus of claim 11 wherein the internal volume of the second body portion is exposed when the pivotally attached door is hanging freely on the hinge bracket.

14. The apparatus of claim 11 wherein the pivotally attached door remains open in a locked position when the flange is interlocked with the hinge bracket.

15. The apparatus of claim 11 wherein the pivotally attached door can be removed from the hinge bracket without the use of tools or fasteners.

16. The apparatus of claim 10 further comprising a plurality of heat sink fins on the exterior side of the housing.

17. A wallpack light fixture comprising:
a housing having a front, a back, and a height, the housing including adjacent upper and lower body portions each defining an internal volume, wherein the upper body portion is above the lower body portion along the height of the housing;
at least one light source mounted within the internal volume of the upper body portion;
a power supply disposed in the internal volume of the lower body portion; and
wherein the front of the housing at the upper body portion has a front face,
wherein the back of the housing at the lower body portion has a rear mounting face configured to mount the wallpack light fixture on a surface,
wherein the front face at the upper body portion is disposed at an angle relative to the rear mounting face at the lower body portion that measures from about 90 degrees to about 170 degrees.

18. The apparatus of claim 17 further comprising a pivotally attached door disposed on the second body portion.

19. The apparatus of claim 17 further comprising a rear conduit entry extending from the exterior of the rear wall to the internal volume of the second body portion.

20. The apparatus of claim 17 further comprising a driver bracket mount coupled to the exterior face of the power supply, wherein the driver bracket mount is disposed within the internal volume of the second body portion.
