Abstract

A finishing section of a recessed wall wash light fixture has a heat conducting side wall. The inner surface of the side wall has a reflective finish. A lamp is non-centrally aligned within the finishing section. The reflective sides cooperate with the off axis location of the lamp to operate as a kick reflector to kick a portion of the light emitted outward from the fixture at high angles to illuminate a nearby wall close to the ceiling line. The finishing section functions as a lamp support, heat shield and kick reflector reducing the number of parts and complexity of assembly typical of wall wash light fixtures. The finishing section is mounted substantially within a rough-in section housing. An aperture cone section, lens, hinge and bias mechanism, and rotatable collar improve performance and functionality of the fixture.

Claims

1. A recessed wall wash light fixture comprising:

a rough-in section housing having a bottom, said bottom having an opening;

a finishing section housing having a substantially cylindrical heat conducting side wall and a top, said side wall having a reflective inner surface and a bottom rim, said bottom rim defining a light exit aperture, said top having a heat ventilating hole therein, said finishing section mounted substantially within said rough-in section housing; and

a non-centrally aligned lamp disposed within said finishing section and offset from said light exit aperture, said lamp also supported by said finishing section, whereby a portion of the light emitted from said lamp is reflected oft of said side wall.

2. The recessed wall wash light fixture of claim 1 wherein said top is dome shaped.

3. The recessed wall wash light fixture of claim 1 said finishing section housing further comprising a bracket attached to said side wall and a lamp housing attached to said bracket, said lamp housing supporting said lamp.

11. The recessed wall wash light fixture of claim 1 further comprising a collar around the lower outer portion of said finishing section housing, said collar being rotatably coupled to said finishing section housing.

12. The recessed wall wash light fixture of claim 1 wherein said finishing section side wall is made of an aluminum material.

13. The recessed wall wash light fixture of claim 1, further comprising an insulation contact housing enclosing said rough-in section housing.

4. A recessed wall wash light fixture comprising:

a rough-in section housing having a bottom, said bottom having an opening;

a finishing section housing having a substantially cylindrical heat conducting side wall, said side wall having a reflective inner surface and a bottom rim, said reflective inner surface being a semi-diffused reflective surface, said bottom rim defining a light exit aperture, said finishing section mounted substantially within said rough-in section housing; and

a non-centrally aligned lamp disposed within said finishing section and offset from said light exit aperture, said lamp also supported by said finishing section, whereby a portion of the light emitted from said lamp is reflected off of said side wall.

5. A recessed wall wash light fixture comprising;

a rough-in section housing having a bottom, said bottom having an opening;

a finishing section housing having a substantially cylindrical heat conducting side wall and a frustoconical aperture cone section, said side wall having a reflective inner surface and a bottom rim, said bottom rim defining a light exit aperture, said aperture cone section being received within said finishing section, said finishing section mounted substantially within said rough-in section housing; and

a non-centrally aligned lamp disposed within said finishing section and offset from said light exit aperture, said lamp also supported by said finishing section, whereby a portion of the light emitted from said lamp is reflected off of said side wall.

6. The recessed wall wash light fixture of claim 5, said aperture cone section having a top rim defining a top opening and a bottom rim defining a bottom opening, said aperture cone section top opening lying in a plane being at an angle to the plane of the aperture cone section bottom opening.
