Hazardous location light fixture housings

1. A housing for a light fixture, the housing comprising:

at least one wall that forms a cavity and a light source housing portion, wherein the at least one wall comprises a thermally-conductive material, wherein the light source housing portion is configured to receive at least one light source;

a wireway disposed between the cavity and the light source housing portion;

a plurality of heat sink fins that extend from an outer surface of the at least one wall; and

at least one air throughway that exposes at least a portion of the wireway between the at least one wall and the light source housing portion, wherein the at least one air throughway allows ambient air to pass directly around the portion of the wireway to remove heat generated by electrical components disposed within the cavity and by the at least one light source, wherein the at least one air throughway is formed independent of the plurality of heat sink fins.

2. The housing of claim 1 , wherein the at least one wall is configured to be rotatable when the light fixture is mounted to a structure, wherein the at least one wall is rotated to orient the at least one air throughway along a path of ambient air flow.

3. The housing of claim 1 , wherein the at least one air throughway is disposed in the at least one wall.

4. The housing of claim 1 , wherein the light source housing portion is part of at least one local housing that is separated from the at least one wall by the wireway.

5. The housing of claim 4 , wherein the at least one local housing has an additional plurality of heat sink fins that extend therefrom, wherein the at least one air throughway is further formed independent of the additional plurality of heat sink fins.

6. The housing of claim 1 , wherein the at least one wall comprises a removable piece that couples to a remainder of the at least one wall, wherein the removable piece is adjacent to the at least one air throughway, wherein removing the at least one piece enlarges the at least one air throughway.

7. The housing of claim 1 , wherein the at least one wall comprises a removable piece that couples to a remainder of the at least one wall, wherein the removable piece comprises a channel that forms an additional air throughway.

8. The housing of claim 1 , wherein the at least one wall and the plurality of heat sink fins are cast as a single piece.

9. A housing for a light fixture, the housing comprising:

at least one wall that forms a cavity, wherein the at least one wall comprises a thermally-conductive material;

at least one positioning feature disposed within the cavity, wherein the at least one positioning feature is configured to movably position at least one component of the light fixture within the cavity against the at least one wall, wherein the at least one component generates heat when operating, and wherein the at least one positioning feature is configured to abut the at least one component against the at least one wall so that the at least one wall absorbs heat generated by the at least one component.

10. The housing of claim 9 , wherein the at least one positioning feature is located on an inner surface of the at least one wall.

11. The housing of claim 10 , wherein the at least one positioning feature comprises a pair of slots configured to slidably receive a thermally-conductive platform on which the at least one component is mounted.

12. The housing of claim 11 , wherein the thermally-conductive platform abuts against the at least one wall.

13. The housing of claim 9 , wherein the at least one positioning feature is configured to push and hold the at least one component against the at least one wall.

14. The housing of claim 13 , wherein the at least one positioning feature is retractable.

15. The housing of claim 9 , wherein the at least one positioning feature comprises an electrical coupling feature that is configured to electrically couple the at least one component to at least one other component.

16. A housing for a light fixture, the housing comprising:

at least one wall that forms a cavity, wherein the at least one wall comprises a thermally-conductive material, a cover receiving feature, and at least one first coupling feature, wherein the cover receiving feature is configured to couple to a cover of the light fixture;

at least one removable wall section removably coupled to the at least one wall, wherein the at least one removable wall section comprises:

at least one second coupling feature that removably couples to the at least one first coupling feature of the at least one wall;

an inner surface comprising the thermally-conductive material that is configured to couple to at least one heat-generating component, wherein the at least one removable section covers an opening in the at least one wall, wherein the at least one heat-generating component is configured to abut against the inner surface so that the inner surface absorbs heat generated by the at least one heat-generating component.

17. The housing of claim 16 , wherein the at least one first coupling feature and the at least one second coupling feature are configured to electrically couple the at least one heat-generating component to another component of the light fixture.

18. The housing of claim 16 , wherein the at least one removable section is thermally isolated from the at least one wall.

19. The housing of claim 16 , wherein the at least one first coupling feature and the at least one second coupling feature, when coupled to each other, form a flame path.
