ABSTRACT:
An illumination system includes a first light source, a second light source, a first light integrating device and a second light integrating device. Each light integrating device includes an input aperture at an input end for receiving input light and a turning mirror at an output end for reflecting light onto an output aperture where the output aperture is positioned in a direction perpendicular to the input aperture. The illumination system further includes a first reflective mirror and a second reflective mirror each coupled to direct light from the respective light source into the input aperture of the respective light integrating device. The illumination system includes a third light integrating device including an input aperture optically coupled to the output apertures of the first and second light integrating devices. The input aperture of the third light integrating device receives light collected by the first and second light integrating devices.
