Abstract
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.
