Abstract

Abstract A "wall wash" assembly for use with a ceiling mounted, recessed lighting fixture comprising a reflector housing having an open end, includes a ring member dimensioned for receipt in the open end of the reflector housing. A concentric ring segment is mounted on the ring member for movement 360° thereabout. An auxiliary reflector is mounted on the ring segment for movement therewith. Positioning of the auxiliary reflector by movement of the ring segment with respect to the ring member provides a desired "wall wash" illumination pattern. An optional baffle member is receivable on the ring member opposite the auxiliary reflector for blocking light emanating from the reflector housing to be excluded in the "wall wash" illumination pattern.

Claim 3
Dependent Claim 57 words
A reflector assembly as claimed in claim 1 wherein said means for removably securing said first ring means on said reflector housing includes clip means attachable to said first ring means, said clip means including protrusions for frictionally engaging the reflective surface of said reflector housing, thereby removably securing said first ring means on said reflector housing.
Claim 4
Dependent Claim 32 words
A reflector assembly as claimed in claim 1 wherein said auxiliary reflector means includes a scoop-shaped reflector for directing light from said light source generally horizontally and downwardly from said lighting fixture.
Claim 5
Dependent Claim 55 words
A reflector assembly as claimed in claim 3 wherein said second ring means extends outwardly of the open end of said reflector housing for positioning a portion of said auxiliary reflector below said lower open end of said reflector housing, said auxiliary reflector portion reflecting light from said source generally horizontally from said lighting fixture.
Claim 6
Dependent Claim 87 words
A reflector assembly as claimed in claim 1 wherein said open end of said reflector housing is circular in shape, wherein said first ring means is circular in shape and dimensioned for receipt within said open end of said reflector housing and wherein said second ring means comprises a semi-circular ring segment mounted on said first ring means for movement therealong, whereby said second ring segment is adjustably positionable on said first ring means for directing reflected light from said auxiliary reflector directionally from said reflector housing.
Claim 7
Dependent Claim 44 words
A reflector assembly as claimed in claim 5 wherein said first ring means defines a rail therealong and said ring segment defines a groove therealong, said ring segment being slidably mounted on said first ring means by receipt of said rail in said groove.
Claim 8
Dependent Claim 48 words
A reflector assembly as claimed in claim 1, further including light baffle means mounted on said outer ring means at a location opposite said auxiliary reflector means for blocking light emanating from said reflector housing in a direction opposite from the light reflected by said auxiliary reflector means.
Claim 9
Dependent Claim 200 words
In a recessed, ceiling mounted lighting fixture including a reflector housing, a source of light mounted in said reflector housing, said reflector housing having a reflective surface for reflecting light from said light source to illuminate an area generally below said fixture, said reflector housing being generally cylindrical in shape, having a circular shaped open lower free end, an adjustable reflector assembly for selectively altering the illumination pattern of said lighting fixture to provide illumination of a wall surface closely adjacent the ceiling in which said lighting fixture is mounted, said adjustable reflector assembly including in combination: a circular ring member, dimensioned for receipt in the open, free end of said reflector housing; means for removably attaching said ring member on said reflector housing; a semi-circular ring segment mounted on said outer ring member, concentrically therewith, said ring segment being movable along said ring member 360° thereabout for repositioning said ring segment at predetermined locations therealong; and auxiliary reflector means mounted on said ring segment for movement therewith along said ring member, said auxiliary reflector means being shaped predeterminedly to direct light from said light source toward said wall surface adjacent the ceiling in which said light fixture is mounted.
