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, wherein the lower body portions 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;

at least one light source mounted within the internal volume of the upper body portion; and
a power supply disposed in the internal volume of the lower body portion.

2. The apparatus of claim 1 further comprising 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.

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

4. The apparatus of claim 3 wherein the pivotally attached door comprises a swinging mount with a flange capable of interlocking with a hinge bracket disposed on the housing.

5. The apparatus of claim 3 wherein a grounding conductor connects the housing and the door.

6. The apparatus of claim 3 wherein the internal volume of the second body portion is exposed when the pivotally attached door is hanging freely.

7. The apparatus of claim 3 wherein the pivotally attached door remains open in a locked position when the flange is interlocked with the hinge bracket.

8. The apparatus of claim 3 wherein the pivotally attached door can be removed from the hinge bracket without the use of tools or fasteners.

9. The apparatus of claim 1 further comprising a raceway disposed between the upper and lower body portions to connect the power supply to the light source.

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

11. 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 lower body portion.

12. The apparatus of claim 11 further comprising a terminal bracket mount, wherein the terminal bracket mount overlies the exterior face of the driver bracket mount.

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

14. The apparatus of claim 2 wherein the heat sink fins are substantially continuous on the exterior rear of the housing.

15. The apparatus of claim 1 wherein the at least one side conduit entry comprises two side conduit entries.

16. The apparatus of claim 15 , wherein the first side conduit entry is located on one side of the lower body portion and the second side conduit entry is located on an opposite side of the lower body portion.
