ABSTRACT:
Apparatus for color illumination of stages, dance floors, skating rinks and the like. Prismatic plates made of a material transparent to light each have parallel triangular prisms. The prisms have an apex of 60 degrees and light sources emitting different primary color light incident on the opposite sides of the individual prisms result in combined beams of primary colors to be emitted by the individual prisms having a width corresponding to a width of a corresponding prism emitting the combined beam. The prismatic plates can be arranged so that the combined beams of the prisms of one prismatic plate are incident on a second prismatic plate having an independent light source mitting a third primary color incident thereon so that each combined beam emitted by the second prismatic plate prisms has three primary colors.
