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.

First claim

What is claimed:

1. A wall wash light fixture comprising:
a housing having 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;
a mounting bracket positioned in the interior and releasably connected to the housing;
a light emitter connected to the mounting bracket; and
a lens having 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, wherein the lens is field removable from the housing without the use of a dedicated tool.

2. The light fixture of claim 1 , wherein the first mounting feature includes a substantially V-shaped protrusion.

3. The light fixture of claim 2 , wherein the second mounting feature includes a groove configured to mate with the V-shaped protrusion.

4. The light fixture of claim 1 , wherein the lens is releasably connected to the housing without any additional fasteners.

5. The light fixture of claim 1 , wherein the base includes an inner surface having a first optical feature.

6. The light fixture of claim 5 , wherein the first optical feature includes a set of serrations.

7. The light fixture of claim 5 , wherein the base includes an outer surface having a second optical feature.

8. The light fixture of claim 1 , wherein a trim frame is integrally formed with the housing extending from a lower edge of the first side wall and the second side wall.

9. The light fixture of claim 8 , wherein the trim frame includes a first section extending from the side wall in a first direction, a second section extending from the first section in a second direction, and a third section extending from the second section in the first direction.

10. A wall wash light fixture comprising:
a housing having 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;
a mounting bracket positioned in the interior and releasably connected to the housing, the mounting bracket including a mounting portion for receiving the light emitter, a first side wall extending from the mounting portion, a second side wall extending from the mounting portion, a first flange extending from the first side wall, and a second flange extending from the second side wall;
a light emitter connected to the mounting bracket;
a lens having a pair of second mounting features configured to mate with the first mounting features to releasably connect the lens to the housing, wherein the lens is field removable from the housing without the use of a dedicated tool.

11. The light fixture of claim 10 , wherein the mounting portion is oriented substantially perpendicular to the lens base.

12. The light fixture of claim 10 , wherein the mounting portion is oriented at an oblique angle to the lens base.

13. The light fixture of claim 12 , wherein the first side wall has a length greater than the second side wall.

14. The light fixture of claim 10 , wherein the first flange includes a set of tabs extending from the flange and the second flange includes one or more openings configured to receive a fastener.

15. The light fixture of claim 14 , wherein the housing includes a set of slots configured to receive the tabs, wherein the tabs pivotally connect the mounting bracket to the housing.

16. A wall wash light fixture comprising:
a housing having an upper wall and a side wall at least partially defining an interior, wherein the side wall includes a lower edge and a first mounting feature positioned between the lower edge and the upper wall;
a mounting bracket positioned in the interior;
a light emitter connected to the mounting bracket;
a lens having a base and an arm extending from the base, wherein the arm includes a second mounting feature configured to mate with the first mounting feature to releasably connect the lens to the housing, and wherein the arm extends at an oblique angle relative to the base and relative to the side wall, wherein the arm includes a notch positioned between the base and the second mounting feature.

17. The light fixture of claim 16 , wherein the area between lower edge and the first mounting feature is defined as a lower region of the side wall and the arm is extends at an angle so it is spaced from at least a portion of the lower region of the side wall.

18. The light fixture of claim 16 , wherein the arm includes a groove configured to mate with the first mounting feature.

19. The light fixture of claim 16 , wherein the lens is field removable from the housing without the use of a dedicated tool.

20. The light fixture of claim 16 , wherein the lens includes a first set of serrations facing a first direction and a second set of serrations facing a second direction.
