Abstract

A wall wash luminaire includes a trim assembly that has a trim and a light re-direction assembly. The light re-direction assembly includes a reflector kicker that is configured to re-direct light from the wall wash luminaire and an optical lens that is coupled to the reflector kicker such that the reflector kicker and the optical lens operate as a single unit. The light re-direction assembly is removably coupled to the trim such that the light re-direction assembly is slidingly rotatable with respect to the trim and 360 degrees about a central axis of the trim assembly.

First claim

What is claimed is:

1. A wall wash luminaire comprising:
a trim assembly that comprises:
a trim comprising a first body extending from a first top annular edge defining a light receiving opening to a first bottom annular edge defining a light exit opening, the first body defining an inner cavity that extends from the light receiving opening to the light exit opening; and a first top flange extending radially outward from the first top annular edge, the first top flange comprising coupling slots formed therein;
a top reflector comprising a second body extending from a second top annular edge to a second bottom annular edge, the second bottom annular edge defining a bottom opening; a second bottom flange extending radially outward from the second bottom annular edge; and reflector tabs that extend out from an outer edge of the second bottom flange, wherein the reflector tabs are configured to engage the coupling slots of the trim to removably couple the top reflector to the trim; and
a light re-direction assembly that comprises:
a reflector kicker; and
a lens that is coupled to the reflector kicker,
wherein the light re-direction assembly is coupled to the trim such that the light re-direction assembly is slidingly rotatable with respect to the trim and about a central axis of the trim assembly.

2. A wall wash luminaire comprising:
a trim assembly comprising:
a trim comprising a first body extending from a first top annular edge defining a light receiving opening to a first bottom annular edge defining a light exit opening, the first body defining an inner cavity that extends from the light receiving opening to the light exit opening; and a first top flange extending radially outward from the first top annular edge, the first top flange comprising coupling slots formed therein; and
a light re-direction assembly comprising:
a reflector kicker; and
a lens coupled to the reflector kicker,
wherein the light re-direction assembly is coupled to the trim such that the light re-direction assembly is slidingly rotatable with respect to the trim and about a central axis of the trim assembly, and
wherein the reflector kicker comprises:

a second body that extends from a second top annular edge to a second bottom annular edge and defines an internal cavity that extends therethrough;
a top collar that extends from the second top annular edge to a collar outer edge; and
coupling tabs that extend out from the collar outer edge,
wherein the coupling tabs of the reflector kicker are configured to engage the first top flange of the trim to removably couple the light re-direction assembly to the trim, and
wherein when the light re-direction assembly is coupled to the trim, the second body of the reflector kicker is disposed in the inner cavity of the trim.

3. The wall wash luminaire of claim 1 , wherein the reflector kicker comprises:
a third body that extends from a third top annular edge to a third bottom annular edge and defines an internal cavity that extends therethrough;
coupling tabs that are disposed adjacent the third top annular edge,
wherein the reflector kicker is coupled to the trim by engaging the coupling tabs with the first top flange of the trim such that the third body of the reflector kicker is disposed in the inner cavity of the trim and the reflector kicker is slidingly rotatable about the central axis of the trim assembly; and

a bottom coupling flange that defines an inner opening that is configured to receive and retain the lens therein,
wherein the reflector kicker is coupled to the trim such that the coupling tabs of the reflector kicker are disposed between the second bottom flange of the top reflector and the first top flange of the trim.

4. The wall wash luminaire of claim 1 , wherein the lens is fixedly coupled to the reflector kicker.

5. The wall wash luminaire of claim 1 , wherein the lens is removably coupled to the reflector kicker.

6. The wall wash luminaire of claim 2 , wherein a height of the second body measured from the second top annular edge to the second bottom annular edge tapers from a first side of the reflector kicker to a second side of the reflector kicker, the first side being opposite to the second side.

7. The wall wash luminaire of claim 1 , wherein the reflector kicker comprises: a third body that extends from a third top annular edge to a third bottom annular edge and defines an internal cavity therethrough; and coupling tabs disposed adjacent the third top annular edge.

8. A wall wash luminaire comprising:
a trim assembly that comprises:
a trim comprising a first body extending from a first top annular edge defining a light receiving opening to a first bottom annular edge defining a light exit opening, the first body defining an inner cavity that extends from the light receiving opening to the light exit opening; and a first top flange extending radially outward from the first top annular edge, the first top flange comprising coupling slots formed therein; and

a light re-direction assembly that comprises:
a reflector kicker; and
a lens that is coupled to the reflector kicker,
wherein the light re-direction assembly is configured to be coupled to a trim of the wall wash luminaire such that the light re-direction assembly is slidingly rotatable with respect to the trim and about a central axis of the trim, and
wherein the reflector kicker comprises:

a second body that extends from a second top annular edge to a second bottom annular edge and defines an internal cavity that extends therethrough;
coupling tabs that are disposed adjacent the second top annular edge,
wherein the reflector kicker is coupled to the trim by engaging the coupling tabs with the first top flange of the trim such that the second body of the reflector kicker is disposed in the inner cavity of the trim and the reflector kicker is slidingly rotatable about the central axis of the trim; and
a bottom coupling flange that defines an inner opening that is configured to receive and retain the lens therein.

9. The wall wash luminaire of claim 8 , further comprising:
a top reflector that comprises a bottom flange, and
wherein the reflector kicker and the top reflector are configured to be coupled to the trim such that: (a) the coupling tabs of the reflector kicker are disposed between the bottom flange of the top reflector and the first top flange of the trim, and (b) a body of the reflector kicker is disposed in an inner cavity that is defined by a body of the trim.

10. The wall wash luminaire of claim 8 , wherein the wall wash luminaire further comprises:
a top reflector that comprises:
a third body that extends from a third top annular edge to a third bottom annular edge, the third bottom edge defining a bottom opening;
a third bottom flange that extends radially outward from the third bottom annular edge; and
reflector tabs that extend out from an outer edge of the third bottom flange,
wherein the reflector tabs are configured to engage the coupling slots of the trim to removably couple the top reflector to the trim.

11. The wall wash luminaire of claim 8 , wherein the reflector kicker comprises:
a top collar that extends from the second top annular edge to a collar outer edge; and
wherein the coupling tabs extend out from the collar outer edge.

12. The wall wash luminaire of claim 8 , wherein the lens is fixedly coupled to the reflector kicker.

13. The wall wash luminaire of claim 8 , wherein the lens is removably coupled to the reflector kicker.

14. The wall wash luminaire of claim 8 , wherein a height of the second body measured from the second top annular edge
