Abstract

A wall wash light fixture includes a housing having an upper wall, a first side wall, and a second side wall at least partially defining an interior. The first side wall and the second side wall each include a first mounting feature having a projection extending into the interior. A mounting bracket is positioned in the interior and releasably connected to the housing. A light emitter is connected to the mounting bracket. A lens has a base, a first arm extending from the base, and a second arm extending from the base. The first and second arms each include a second mounting feature configured to mate with the first mounting feature to releasably connect the lens to the housing.

Claims (29)

1. A method of assembling a wall wash light fixture comprising:

selecting a housing from one or more housing types;

selecting a light emitter mounting bracket from a plurality of mounting brackets, wherein the different mounting brackets are associated with different light output directions;

selecting a lens from a plurality of lenses, wherein the different lens are associated with different light outputs;

connecting the mounting bracket to the housing; and

connecting the lens to the housing, wherein the lens is connected and removably secured without the use of a dedicated tool.

2. The method of claim 1 , wherein selecting a light emitter mounting bracket includes selecting from a group including a mounting bracket configured to emit light substantially downward from the housing orthogonal to a major surface of the lens.

3. The method of claim 1 , wherein selecting a light emitter mounting bracket includes selecting from a group including a mounting bracket configured to emit light at an oblique angle relative to a major surface of the lens.

4. The method of claim 1 , wherein selecting a light emitter mounting bracket includes selecting from a group including a mounting bracket configured to emit light at a first oblique angle relative to a major surface of the lens and a second oblique angle relative to the major surface of the lens, wherein the second oblique angle is opposite the first oblique angle.

5. The method of claim 1 , further comprising positioning a driver in the housing, wherein the driver is inaccessible to a user when changing the lens.

6. The method of claim 1 , wherein the housing includes a V-shaped protrusion configured to mate with the selected lens.

7. The method of claim 1 , wherein selecting a lens includes selecting from a group including a lens having an outer surface with a first set of serrations and an inner surface with a second set of serrations.

8. The method of claim 7 , wherein the size of the serrations grow from a center of the lens toward an outer portion.

9. The method of claim 1 , wherein selecting a lens includes selecting from a group including a lens having a substantially planar outer surface and an inner surface with a set of serrations.

10. The method of claim 9 , wherein the serrations face a first direction on a first portion of the lens and face a second direction on a second portion of the lens.

11. A method of modifying the light output of a wall wash light fixture comprising:

removing a first lens having a first light distribution from a housing without the use of a dedicated tool; and

connecting a second lens having a second light distribution to the housing without the use of a dedicated tool,

wherein the housing includes an upper wall, a first side wall, and a second side wall at least partially defining an interior, wherein the first side wall and the second side wall each include a first mounting feature having a projection extending into the interior, and

wherein the lens includes a base, a first arm extending from the base, and a second arm extending from the base, wherein the first and second arms each include a second mounting feature configured to mate with the first mounting feature to releasably connect the lens to the housing.

12. The method of claim 11 , wherein the first mounting feature includes a V-shaped projection.

13. The method of claim 12 , wherein the second mounting feature includes a groove.

14. The method of claim 11 , wherein the first lens or the second lens has an outer surface with a first set of serrations and an inner surface with a second set of serrations.

15. The method of claim 14 , wherein the size of the first and second serrations grow from a center of the lens toward an outer portion.

16. The method of claim 14 , wherein the first and second serrations face a first direction on a first portion of the lens and face a second direction on a second portion of the lens.

17. The method of claim 14 , wherein the first set of serrations have an angled, tapered surface.

18. The method of claim 11 , wherein selecting a lens includes selecting from a group including a lens having a substantially planar outer surface and an inner surface with a set of serrations.

19. The method of claim 18 , wherein the serrations face a first direction on a first portion of the lens and face a second direction on a second portion of the lens.

20. The method of claim 11 , wherein a driver is positioned in the housing and is inaccessible to a user when changing the lens.
