AB - An illumination system for a microdisplay projector with a two-step imaging system is described here. In the first step,an imaging condenser creates an image of the LED at the color combiner entrance window. In the second step, we relaythe image of the integrator exit window onto the micro-display. The illuminator demonstrates high collection efficiency,small footprint, and efficient mixing of light from RGB LEDs that provides required uniformity. A variety of approachesto collecting light emitted from LEDs of various types are compared, leading to the two-step design. A design exampleusing a 0.55” diagonal DLP-based optical engine is presented with the following characteristics:Footprint: 3.9”x3.3”x2.0” (25.7 cubic inches)Light output: 338 white lumensEfficiency: 4.7 lm/watt
