ABSTRACT:
A lighting unit for indirect illumination of an area. The unit has a reflective surface contoured to direct reflected light rays from a source generally upward at predetermined angles for reflection by a surface above the lighting unit providing a symmetrical lighting pattern over the area to be illuminated. The reflective surface is contoured so as to eliminate glare interference to the area to be illuminated by controlling the angle of emanation of the light rays from the lighting unit.
