Patent ID: 8625097

Claim:
A light engine, comprising: a first light source, wherein the first light source includes a first Light Emitting Diode (LED), a first bandpass filter, and a first collimator, wherein the first light source emits a first collimated light beam of a first color; a second light source, wherein the second light source includes a second Light Emitting Diode (LED), a second bandpass filter, and a second collimator, wherein the second light source emits a second collimated light beam 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), a third bandpass filter, and a third collimator, wherein the third light source emits a third collimated light beam of a third color different than the first color and second color; a fourth light source, wherein the fourth light source includes a fourth Light Emitting Diode (LED), a fourth bandpass filter, and a fourth collimator, wherein the fourth light source emits a fourth collimated light beam of a fourth color different than the first color, second color, and third color; a first laser light source, wherein the first laser light source emits a first coherent light beam of a first wavelength; a plurality of reflective optical components positioned so as to direct the first collimated light beam of the first color, the second collimated light beam of the second color, the third collimated light beam of the third color, the fourth collimated light beam of the fourth color, and the first coherent light beam onto a main optical axis of the light engine; and a light guide positioned to receive said light beams directed onto the main optical axis of the light engine for transport to a device to be illuminated.
