摘要： An illumination source includes a number of light emitting diodes (LEDs) operating at a first wavelength. Light from the LEDs illuminates a phosphor material that generates light at a second wavelength. A reflective polarizer transmits light at the second wavelength in a first polarization state and reflects light at the second wavelength in a second polarization state orthogonal to the first polarization state. The light at the second wavelength reflected by the reflective polarizer is directed back towards the phosphor material without an increase in angular range. In some embodiments the LEDs, having a conformal layer of phosphor material, are attached directly to the first surface of a liquid cooled plate. A liquid coolant contacts a second surface of the plate.

摘要： Projection lenses for use with pixelized panels (PP) are provided. The projection lenses have first and second lens units (U1,U2), with the first lens unit having a negative or weakly positive power and the second lens unit having a positive power. The second lens unit has first and second subunits (U2S1 and U2S2) which provide positive power followed by negative power. The second subunit (U2S2) of the second unit (U2), in turn, has negative power followed by positive power. In this way, an overall short projection lens (e.g., BRL/f 0 ≤ 0.9) along with small lens elements (e.g., CA max /f 0 ≤ 0.8) can be achieved.

摘要： The present invention is particularly useful for projection systems in which portions of an unwanted light beam overlap with the image beam. Such an overlap reduces the image contrast. Under the present invention, an aperture (122) is used to restrict the extent of the unwanted beam while an integrator (112) changes the shape of the light beam illuminating the image display device (106). The integrator (112) changes the illumination beam so as concentrate the light in those areas of the illumination beam that are transmitted through the aperture (122). When the aperture and the integrator are used together in the projection system, both the image brightness and the image contrast are increased.
摘要翻译：本发明对于其中不想要的光束的部分与图像束重叠的投影系统特别有用。这样的重叠减少了图像的对比度。在本发明中，当积分器（112）改变照射图像显示装置（106）的光束的形状时，使用孔（122）来限制不需要的光束的范围。积分器（112）改变照明光束，以便将光集中在透过孔（122）的照明光束的那些区域中。当在投影系统中一起使用光圈和积分器时，图像亮度和图像对比度都增加。

摘要： Projection lenses for use with pixelized panels (PP) are provided. The projection lenses have first and second lens units (U1,U2), each of which can contain just two optical components, e.g., L M and L P1 for the first lens unit and L DB and L P2 for the second lens unit. The second lens unit can contain a hybrid component (e.g., L P2 ) which comprises a glass base to which is attached a layer (M) of a formable material which has an external surface which is aspheric. The use of a hybrid component allows the projection lens to have reduced thermal drift, a reduced optical component count, and a short barrel length. The first lens unit can include an additional negative lens element L N to improve the moldability of L M , and the second lens unit can include a molded glass asphere rather than a hybrid component.

摘要： In a projection system, an illumination unit directs light to a spatial light modulator, via a prism having first, second and third sides. At least some of the illumination light from the illumination unit enters the prism through the first side, is totally internally reflected at the second side and exits the third side of the prism to the spatial light modulator. The illumination light is incident on the first side along a first axis, the first axis being directed with a component directed towards the spatial light modulator. In some cases, the first prism may introduce prism aberrations to the illumination light. The light from the illumination unit is directed to the prism by light handling optics. The light handling optics compensate, at least in part, for the prism aberrations.
