Abstract: A light fixture for lighting a surface includes a housing, a plurality of light sources, and a reflector for directing light out of a window of the housing. The plurality of light sources are directed away from the window of the housing and are then not directly viewable from the exterior of the housing while providing light reflected against the reflector through the window of the housing. The light sources are connected to a substrate through which power is supplied to the light sources and through which heat energy is removed from the light sources during operation. The substrate may form a portion of the housing of the light fixture.
