Abstract
Abstract A light reflection system for indirect lighting, such system being adapted for mounting on a wall or other structure in an office area or the like, comprising a boxlike housing having a central compartment in which the light reflection system is contained, such system including a high intensity discharge source of light, and a reflector assembly including a specially configured reflector which substantially surrounds the light source and judiciously reflects the light upwardly to the ceiling of the room being lighted; other, flat, reflectors are also included as part of the system.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
184 words
A light reflection system adapted to be mounted on the wall of a room for providing essentially uniform indirect lighting for the room comprising: a housing having front and rear walls, a bottom wall, and side walls, and having an extended opening at its top; a light source disposed in a horizontal orientation, said source being parallel to the rear wall of said housing and closer to the rear wall than to the front wall; an asymetric distribution means in the form of a reflector assembly enclosed by the housing, said assembly including a main reflector wrapped substantially around said light source, said reflector extending longitudinally approximately 250° around said light source from approximately a twelve o'clock position to approximately a four o'clock position, as seen at the left side of said housing when mounted; said main reflector having a reflecting, corrugated, inner surface comprising a series of at least six contiguous facets located adjacent said twelve o'clock position, said facets having appropriately selected varied angles so as to reflect light rays in a generally horizontal direction thereby to provide uniform distribution of light.
Claim 2
Dependent Claim
184 words
A light reflection system adapted to be mounted on the wall of a room for providing essentially uniform indirect lighting for the room comprising: a housing having front and rear walls, a bottom wall, and side walls, and having an extended opening at its top; a light source disposed in a horizontal orientation, said source being parallel to the rear wall of said housing and closer to the rear wall than to the front wall; an asymetric distribution means in the form of a reflector assembly enclosed by the housing, said assembly including a main reflector wrapped substantially around said light source, said reflector extending longitudinally approximately 250° around said light source from approximately a twelve o'clock position to approximately a four o'clock position, as seen at the left side of said housing when mounted; said main reflector having a reflecting, corrugated, inner surface comprising a series of at least six contiguous facets located adjacent said twelve o'clock position, said facets having appropriately selected varied angles so as to reflect light rays in a generally horizontal direction thereby to provide uniform distribution of light.
Claim 3
Dependent Claim
59 words
A system as defined in claim 1, in which said reflector assembly includes an auxiliary, flat reflector which is attached to said main reflector and extends upwardly therefrom at an angle of approximately 30° from the horizontal, said flat reflector transversely terminating adjacent the side walls of said housing, and longitudinally terminating at the front wall of said housing.
Claim 4
Dependent Claim
41 words
A system as defined in claim 2, further including a lens extending from the point at which said flat reflector is attached to the main reflector to the top of said housing at an angle of approximately 45° from the horizontal.
Claim 5
Dependent Claim
18 words
A system as defined in claim 1, in which said light source comprises a high intensity discharge lamp.
Claim 6
Dependent Claim
34 words
A system as defined in claim 1, in which said housing is subdivided into three compartments, a main compartment and two side or auxiliary compartments, the light source being disposed in said main compartment.
Claim 7
Dependent Claim
26 words
A system as defined in claim 5, in which an additional reflector is provided in a vertical orientation at each opposite end of said main compartment.
