Patent ID: 8493564

Claim:
An illumination system, comprising: a first light source, wherein the first light source includes a first Light Emitting Diode (LED) and a first collimator, 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) and a second collimator, 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) and a third collimator, 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 having a fourth collimator, wherein the fourth light source emits a fourth collimated beam of light of a fourth color different than the first color, second color, and third color; wherein the fourth light source includes a luminescent rod and an array of Light Emitting Diodes (LEDs), wherein the luminescent rod is adapted to emit the light of a fourth color in response to absorbing excitation light received from the array of Light Emitting Diodes (LEDs), the excitation light having a different color than the fourth color; and associated optics, wherein the associated optics direct the first collimated beam of light of the first color, the second collimated beam of light of the second color, the third collimated beam of light of the third color, and the fourth collimated beam of light of the fourth color onto a main optical axis.
