Lighting unit for providing indirect light of uniform intensity

摘要

A lighting unit for indirect illumination of an area. The unit has first and second reflective surfaces 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 substantially uniform intensity of light over the area to be illuminated. The lighting unit may have cut-off baffles for redirecting the light rays away from nearby or adjacent vertical surfaces providing an asymmetrical substantially uniform intensity of light over the area to be illuminated.
