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.

A light source module and a collimation lens are arranged at the bottom face of the primary prism to project red, green, and blue lights onto one of the slope faces of the primary prism to be consolidated by a wedge prism group and reflected toward a polarization beam splitting wedge prism arranged at another slope face, where the light is split into two polarized lights that are then emitted out of the primary prism to be processed and combined as light of consistent polarization by a lens array and a polarization conversion film so as to facilitate condensation and projection of the light by a polarization beam splitter and a projection lens.

摘要： An optical projection system can receive a red light beam, green light beam, and blue light beam. The optical projection system includes a color-combination prism, and the light beams respectively enter the color-combination prism from three surfaces and are combined into a mixed light beam, which exits from another surface. A projection lens set receives the mixed light beam to perform the projection. Each of the light beams further includes a liquid crystal reflection panel and a wire grid polarizer (WGP). The liquid crystal reflection panel is parallel to the corresponding surfaces of the color-combination prism. In the design, before the light beam entering the color-combination prism, they are first reflected by the WGP onto the liquid crystal reflection panel, and the liquid crystal reflection panels respectively with a polarizing state reflect the light beams, passing through the WGP and directly propagating toward the color-combination prism.

摘要： The invention relates to a liquid crystal display projector with a lens protecting device capable of protecting and positioning lens of liquid crystal display projector. The lens protecting device of the invention comprises a cover, a top housing, a bottom housing, an actuating device, a plurality of springs and a mirror, where the lens is secured in the top housing and the actuating device also is connected to the top housing. Moreover, the mirror is located in the cover, and the top housing and the bottom housing are connected to each other by said springs. Further, the cover can be connected to the top housing or the projector with at least one hinge and projection of the projector is adjusted by only rotating the cover around the hinge. When the top housing is gradually covered by the cover, the actuating device will touch the top housing and deform these springs such that the top housing is located into the LCD projector and the lens is located in the protecting position. Therefore, When the LCD projector does not be operated, the lens is covered by the cover and disadvantages such as dirty and scare are properly protected. On the other hand, when the LCD projector is operating, lens is positioned to the projecting position by these springs.
