ABSTRACT:
A light engine for image display projectors has a plurality of monochromatic light sources, typically red, blue and green, combined into one light generation device powered by microwaves pulsed at 3-5 KHz rates. The light engine has a microwave power supply, microwave coupling cavity, a microwave coupler coupling a microwave signal from the microwave power supply to the microwave coupling cavity, and the plurality of monochromatic light sources disposed in the microwave coupling cavity and powered by the microwave signal. The microwave coupling cavity includes a plurality of resonance points, each of the monochromatic light sources being located respectively at one of the resonance points.
