摘要： A high efficiency light combination module of projection system includes a cubic polarizing beam splitter prism serving as a main body around which four lens arrays, three retarders, and three optical plates are arranged, which is used in combination with coatings that enables transmission or reflection of specific lights to allow different color lights incident from different directions to be combined as a single illumination light beam and to allow the single illumination light beam so combined to be uniform by the lens arrays to facilitate light collection and projection by a panel and a projection lens arranged behind. A polarization conversion film is set at light outgoing port to transfer the polarization states of the combined single illumination light beam into a specific polarized light for a liquid crystal projection system.
