Abstract

A wall-wash lighting fixture is provided. The wall-wash lighting fixture includes a solid-state light source having a light emitting surface configured to emit light. The light emitting surface is a long dimension of the light emitting surface. The wall-wash lighting fixture further includes a frustoconical structure. The solid-state light source is positioned to emit light into the frustoconical structure. The wall-wash lighting fixture includes a reflector coupled to the frustoconical structure such that light exiting frustoconical structure is reflected at a non-parallel angle relative to a vertical axis associated with the wall-wash lighting fixture. The reflector defines an opening.

Claims (29)

1. A wall-wash lighting fixture, comprising:

a solid state light source having a light emitting surface configured to emit light, the light emitting surface having a length dimension;

a frustoconical structure positioned adjacent the solid state light source such that the light emitting surface emits light into the frustoconical structure; and

a reflector defining an opening and a central axis extending through the opening, the reflector coupled to the frustoconical structure and arranged relative to the frustoconical structure such that light exiting the frustoconical structure is reflected by the reflector at a non-parallel angle relative to the central axis of the reflector,

wherein a diameter of the opening defined by the reflector is between about 7.2 and 9.7 times greater than the length dimension of the light emitting surface.

2. The wall-wash lighting fixture of claim 1 , wherein the diameter of the opening defined by the reflector is between 7.6 and 9.4 times greater than the length dimension of the light emitting surface.

3. The wall-wash lighting fixture of claim 1 , wherein the reflector includes a kicker portion, and wherein an angular span of the kicker portion defined along an azimuthal direction is greater than 115 degrees.

4. The wall-wash lighting fixture of claim 1 , wherein the reflector includes a kicker portion, and wherein an angular span of the kicker portion defined along an azimuthal direction is greater than 120 degrees and less than 230 degrees.

5. The wall-wash lighting fixture of claim 1 , wherein the diameter of the opening defined by the reflector is less than 3.5 inches.

6. The wall-wash lighting fixture of claim 1 , wherein the diameter of the opening defined by the reflector is between 2.5 inches and 3.1 inches.

7. The wall-wash lighting fixture of claim 1 , wherein the diameter of the opening defined by the reflector is less than 3 inches.

8. The wall-wash lighting fixture of claim 1 , wherein a height of the wall-wash lighting fixture is between 7.2 and 9.6 times greater than the length dimension of the light emitting surface.

9. The wall-wash lighting fixture of claim 1 , wherein a height of the wall-wash lighting fixture is between 7.4 and 9.4 times greater than the length dimension of the light emitting surface.

10. The wall-wash lighting fixture of claim 1 , wherein a height of the wall-wash lighting fixture is less than about 3.0 inches.

11. The wall-wash lighting fixture of claim 1 , wherein the solid state light source comprises a light emitting diode (LED) light source.

12. A wall-wash lighting fixture, comprising:

a solid state light source having a light emitting surface configured to emit light;

a frustoconical structure positioned to receive light emitted from the solid state light source; and

a reflector defining an opening and a central axis extending through the opening, the reflector coupled to the frustoconical structure and including a kicker portion, the reflector arranged to receive light exiting the frustoconical structure and reflect the light at a non-parallel angle relative to the central axis of the reflector,

wherein an angular span of the kicker portion defined along an azimuthal direction is greater than about 115 degrees.

13. The wall-wash lighting fixture of claim 12 , wherein the angular span of the kicker portion is greater than about 120 degrees and less than about 230 degrees.

14. The wall-wash lighting fixture of claim 12 , wherein the reflector defines an opening having a diameter, and wherein the diameter of the opening is between 7.2 and 9.7 times greater than a length dimension of the light emitting surface.

15. The wall-wash lighting fixture of claim 12 , wherein the reflector defines an opening having a diameter, and wherein the diameter of the opening is between 7.6 and 9.4 times greater than a length dimension of the light emitting surface.

16. The wall-wash lighting fixture of claim 12 , wherein a height of the wall-washing fixture is between 7.2 and 9.6 times greater than a length dimension of the light emitting surface.

17. The wall-wash lighting fixture of claim 12 , wherein a height of the wall-washing lighting fixture is between 7.4 and 9.4 times greater than a length dimension of the light emitting surface.

18. The wall-wash lighting fixture of claim 12 , wherein the reflector includes an opening having a diameter, and wherein the diameter of the opening is less than about 3.5 inches.

19. The wall-wash lighting fixture of claim 12 , wherein the reflector includes an opening having a diameter, and wherein the diameter of the opening is between 2.5 inches to 3.1 inches.

20. The wall-wash lighting fixture of claim 12 , wherein the reflector includes an opening having a diameter, and wherein the diameter of the opening is less than about 3 inches.

21. The wall-wash lighting fixture of claim 12 , wherein the solid state light source comprises a light emitting diode (LED) light source.
