ABSTRACT:
A light illumination apparatus and method for providing a light source includes light emitting diodes (LEDs) (101, 102, 103) and optical waveguides (104, 105, 106) associated with the light sources for guiding the light to the nonpolarized dichroic combiner (107). The dichroic combiner (107) combines the light from the wave guides into a single light source. Lenses (207, 208, 209) may also be used to focus light from the waveguides to the dichroic combiner (107). The invention provides an efficient approach to provide a single source of light using LEDs.
