Patent Number:	4535394
Title:	Variable Color Floodlight
Abstract:	A lighting system for use with a spotlight or floodlight in which the color of the light may be continuously varied. Red, blue, and green collimated light sources are provided adjacent a pyramidal mirror assembly having a set of crossed dichroic filters. One dichroic filter passes red and green light and reflects blue light; the other dichroic filter passes blue and green light and reflects red light. The dichroic mirrors serve to direct the red, blue, and green light beams from the sources to one mirror of the mirror assembly which reflects a composite beam produced by the addition of the three primary color components. Individual intensity controls are provided for the three light sources permitting a continuous variation in color of the composite beam.
