摘要

Enhancement and duration of the projector luminance play two key roles in the difficulties of existing projectors. The paper proposes an optimized and novel dual-lamp Illumination module, whose designs would be based not only on easy exchange with lamps in existing projector systems, but also on imposing minimal visual burdens on students In conventional classrooms. Applying these requirements to engineering specifications, the illumination module should comply with the following conditions. The total flux on the screen Is larger than 1200 Im. The lifetime is longer than 2 years. The lamp module is easily attached to the optical engines in known mass-produced projectors. In order to achieve these conditions, the ray aberrations of burners and the structure of the dual-lamp module are presented and analyzed for optimization. Simulation and experimental results prove that the luminance of the module can be increasesd by about 1.47 times over that of a conventional projector under the stated requirements. Finally, a collateral-type dual-lamp module Is also proposed for the further improvement. The simulation results show a further increase of 1.58 times in luminance over the single-lamp module and 11% over the dual-lamp module.
