LUMINAIRE EXHIBITING SECONDARY GLOW CHARACTERISTICS

摘要

A luminaire includes a housing having at least one sidewall with an observable outer surface and a light feed edge. The housing sidewall is characterized in that light introduced through a light feed edge of the sidewall will propagate by internal reflections through the sidewall and will be extracted from the outer surface of the sidewall. A fractional amount of light emitted by the luminaire's light source is directed to the sidewall's light feed edge. When extracted, this fractional amount of source light produces an observable and aesthetically pleasing glow of light on the sidewall of the housing.

主权项

1. A luminaire comprising:
a housing having at least one sidewall, said housing sidewall having an observable outer surface and a light feed edge, and being characterized in that light introduced into the sidewall through the light feed edge thereof will propagate by internal reflections within the sidewall, at least one light source in said housing for emitting light that emanates from the housing in a light distribution pattern, optical control means for directing a portion of the light emitted by said light source to the light feed edge of the housing sidewall, wherein said portion of light is introduced into the sidewall of the housing through the light feed edge thereof, said housing sidewall further being characteristic in that light propagating within the sidewall is extracted through the outer surface thereof to produce a secondary observable glow of light thereon.
