ABSTRACT:
A tricolor lighting system uses first and second dichroic filters or mirrors to separate light into different colors, primarily red, green, and blue. The light is directed into input ends of respective first, second, and third light guides for a desired end use at a remote location. Various embodiments use either paraboloid or ellipsoidal reflective surfaces associated with the light source and in selected embodiments, the first and second mirrors are disposed in a crossed relation to provide a compact system.
