Patent Number: 5515254 
Title: Automated Color Mixing Wash Luminaire 
Abstract: An automated color mixing wash luminaire includes a movable yoke and a housing movably connected to the yoke. The housing has a first portion including a light source and provides for removing heat generated from the light source. A second portion of the housing includes movable color filters and a power lens. The light source is operable to project a beam of light along a path through the color filters and the lens. Heat removal is provided by cooling fins and at least one heat filter supported in the path of the beam so that a portion of the beam passes through the heat filter and a portion of the beam is reflected from the path toward the cooling fins. The power lens is formed by a disc of cast transparent material including several lens elements in a honeycomb pattern. Each lens element has a convex surface. At least one of the color filters is a gradient density color filter formed of a disc-shaped substrate having a planar surface including a photolithograpically etched film deposited thereon. The film forms a Gausian pattern arcuate band extending around a substantial portion of the planar surface. The band has inner and outer edges and the density of the film is greater in an area along a radius between the inner and outer edges and less along the radius at the inner and outer edges.
