The technique of DLP optical projection is a sort of major techniques of optical projection. The traditional optical engine uses a UHP lamp, a light pipe and a color recapture as the major components of an optical engine. This study provides an optical engine that is suitable for the new type of DLP system: replacing the UHP lamp with LEDs to reduce the energy consumption; replacing the light pipe with the CPC to reduce the size of the optical engine, and replacing the color recapture with color LEDs for allowing DLP color output to be fully controlled by a circuit. The result that vie acquired through the simulation on the optical engine simulated by the optical simulation software, TracePro, has shown that the optical engine's performance of the new type of DLP system tallied with the performance of the traditional DLP optical engine. This result has proved that the new type optical engine designed in this study could replace the traditional one. In addition, its volume is smaller; it saves more energy, and it could achieve the color management with higher efficiency.
