  • Patent number: 4335421
    Abstract: A light fixture having an optically diffusive viewing element having a viewing area across which apparent uniform brightness is achieved from a conventional light source and reflector by utilization of a light aperture. The light aperture comprises a tralucent substrate to which a plurality of reflective surfaces are affixed so as to partially redirect light incident thereon back to the reflector. Apparent uniform brightness of the light fixture viewing area is derived by a unique method of dividing the light from the light source into varying portions of direct and indirect illumination through the light aperture as well as direct illumination from the light source and indirect reflection from the reflector to the viewing area.
