  • Patent number: 4564888
    Abstract: A "wall-wash" lighting fixture is mounted on the ceiling along the top of a wall to be provided with a substantially uniform illumination downwardly from the fixture. An elongated fluorescent bulb is used as the source of light; and the reflector is comprised of at least a central section and two shorter end sections. The cross-section of the central section of the reflector differs from the cross-section of the end sections in a manner to cause greater amounts of light to be reflected a greater distance downwardly on the wall from the center section than from the end sections. This compensates for the non-uniform light intensity from the fluorescent bulb, and results in a more uniform illumination of the wall below the fixture.
