Abstract
A high performance color mixing system combines colored light beams from three primary color sources into a composite light beam. Each light source assembly can be individually dimmed to control the color of the composite beam. Each primary color beam can be varied in hue and saturation by the use of pivoting dichroic filters, thereby providing improved performance and increased capability. This system is capable of producing deeply saturated colors in all hues, and does not comprise performance in white, provides good color balance and sufficient intensity when the dichroic filters are pivoted to a position parallel to the light rays of the beam.
