摘要： A light source module includes a light source, a paraboloid reflector and an aspheric lens. The light source is used for generating a first light. The paraboloid reflector is used for reflecting the first light beam to form a second light. The aspheric lens is used for converging the second light. The aspheric lens includes an aspheric incident surface and an emergent surface. The aspheric incident surface is used for converging the second light beam into a third light, and the emergent surface is used for converging the third light. The emergent surface includes two aspheric curved surfaces configured symmetric to an optical axis of the aspheric lens.

摘要： An optical projection device and polarizing light source module are provided. The polarizing light source module includes a light source, a reflector and an optical sheet with a polarization splitting portion and a polarization conversion reflection portion. The light source provides an un-polarized light. The reflector with a reflection curved surface covers the light source with the optical sheet. A first polarized light passes through the polarization splitting portion and a second polarized light is reflected by that and passes to the reflection curved surface, then the second polarized light is reflected by the reflection curved and passes to the polarization conversion reflection portion. The second polarized light is converted to the first polarized light by the polarization conversion reflection portion, and the first polarized light reflected by the polarization conversion reflection portion is reflected by the reflection curved surface and penetrates through the polarization splitting portion.

摘要： In a projection display that includes a polarization beam splitter prism and two reflective light valves, each of a pair of dichroic beam splitters is disposed between the polarization beam splitter prism and a respective one of the reflective light valves. The arrangement as such ensures that only a minimal amount of light leakage components will reach a projection lens of the projection display so as to achieve optimum image quality.

摘要： An illuminating apparatus is adapted to supply input light to a light-processing unit of a projection display, and includes a lighting unit, a lens unit and a light integrator. The lighting unit includes a plurality of lamp bases, each of which is operable so as to generate forwardly directed light rays. The lens unit is adapted to be disposed between the lighting unit and the light-processing unit so as to receive the forwardly directed light rays from the lamp bases. The light integrator has an input side facing the lens unit so as to receive the light rays that pass through the lens unit, and an output side adapted to face the light-processing unit. The light rays that are received from the lens unit are radiated by the light integrator as an evenly distributed light source at the output side for reception by the light-processing unit.

摘要： A high-resolution variable focus lens system that has an extra-long back focal length with a telecentric design. The lens system includes three groups of lenses between an object (screen) and an image (a liquid crystal panel). The first group of lenses, comprising three lenses and having a negative power, is used for focusing and zooming of the lens system. The second group of lenses, comprising two lenses and having also a negative power, is used for zooming of the lens system. The third group of lenses, comprising six lenses and having a positive power, is similarly used for zooming of the lens system.
