A set of primary light sources (such as RGB light source) with a light source controller is utilized to replace the UHP lamp. The color wheel has multiple color filter segments that are sequentially disposed on the path of the light when the wheel rotates. Based on a sync signal received from the rotating color wheel, the light source controller sequentially turns the primary light sources on and off in accordance with the sequence of the color filter segments of the color wheel. During each of the spoke periods, to generate a varying mixture of the two color lights, at least two primary color light sources are turned on simultaneously. | 05-09-2013 |
