Claim Text:
1. An illumination system, comprising: a first light source, wherein the first light source includes a first Light Emitting Diode (LED) wherein the first light source emits a first collimated beam of light of a first color; a second light source, wherein the second light source includes a second Light Emitting Diode (LED), wherein the second light source emits a second collimated beam of light of a second color different than the first color; a third light source, wherein the third light source includes a third Light Emitting Diode (LED), wherein the third light source emits a third collimated beam of light of a third color different than the first color and second color; a fourth light source, wherein the fourth light source comprises a plurality of emitters of excitation light of an excitation color and a luminescent material positioned to receive the excitation light from all of the plurality of emitters of excitation light and emit light of a fourth color different than the excitation color, the first color, the second color, and the third color, whereby the fourth light source emits a fourth collimated beam of light of the fourth color; a plurality of reflective optical components positioned to direct the first collimated beam of light, second collimated beam of light, third collimated beam of light and fourth collimated beam of light onto a main optical axis of the illumination system; and an output system positioned to receive light from said main optical axis of the illumination system and configured to focus said light from said main optical axis into an output beam configured to fill an input aperture of a fiber optic or liquid light guide.
