摘要： Optical elements, color combiners using the optical elements, and image projectors using the color combiners are described. The optical element includes light recycling stacks, a polarizing beam splitter, and a color-selective stacked retardation polarizing filter. The polarizing beam splitter includes a first reflective polarizer aligned to a first polarization direction. Each light recycling stack includes a second reflective polarizer aligned to the first polarization direction, and a retarder aligned at 45 degrees to the first polarization direction. The color combiner includes partially reflective light sources coupled to the optical element. Un-polarized light having different colors can enter the color combiner through the light recycling stacks, and combined light of a desired polarization state can exit the color combiner. Light having an undesired polarization state can be recycled to the desired polarization state within the color combiner, so that light utilization efficiency is increased. The image projector includes a color combiner coupled to an imaging source and projection elements, so that a first portion of the combined light is directed to the projection element, and a second portion of the combined light is recycled back into the color combiner.

摘要： Light combiners and light splitters, and methods of using light combiners and light splitters are described. In particular, the description relates to light combiners and splitters that combine and split, respectively, light of different wavelength spectrums using polarizing beam splitters. The polarizing beam splitters include a reflective polarizer to efficiently split incident light into transmitted and reflected beams having different polarization directions. Reflectors and quarter-wave retarders are positioned facing selected prism faces of the polarizing beam splitters, to affect the polarization state of light passing through the prism faces. The reflectors can be dichroic filters adapted to reflect light that is outside a selected wavelength range, so that light of different wavelength spectrums can be affected at different prism faces. The surfaces of each polarizing beam splitter can be polished so that the light utilization efficiency is increased due to total internal reflection within the polarizing beam splitter. The light combiners can combine up to five unpolarized different color lights to produce an unpolarized polychromatic light output, which may be white light useful for a projection display. The light splitters can split unpolarized polychromatic light to produce up to five unpolarized different color light outputs.
摘要翻译：光组合器和光分离器以及使用光组合器和分光器的方法被描述。特别地，该描述涉及使用偏振分束器分别组合和分离不同波长光谱的光的光组合器和分束器。偏振分束器包括有效地将入射光分离成具有不同偏振方向的透射和反射光束的反射偏振器。反射器和四分之一波长延迟器被定位在偏振分束器的选定的棱镜面上，以影响穿过棱镜面的光的偏振状态。反射器可以是适于反射在选定波长范围外的光的二向色滤光片，使得不同波长光谱的光可以在不同的棱镜面受到影响。每个偏振分束器的表面可以被抛光，使得由于偏振分束器内的全内反射而增加光的利用效率。光组合器可以组合多达五个非偏振的不同颜色的光以产生非偏振多色光输出，其可以是用于投影显示的白光。分光器可以分离非偏振多色光，产生多达五个非偏振的不同颜色的光输出。

摘要： A compound polarization beam splitter (33) for use with a reflective, polarization-modulating, imaging device (10), e.g., a LCoS device, is provided. The compound PBS has: (a) an input prism (20); (b) an output prism (30), and (c) a polarizer (13), which is located between the two prisms (20,30) and which may be a wire grid polarizer (13a) or a multi-layer reflective polarizer (13b). Polarized illumination light (11) enters the input prism (20) through a first surface (21) and undergoes total internal reflection at a second surface (22) before being reflected from the polarizer (13) and polarization-modulated at the imaging device (10). The polarizer's tilt angle (β) is less than 45°, which reduces astigmatism and the required back working distance of the system's projection lens (74).

摘要： Light reflectors and flood lighting systems for illumination and lighting. Each light reflector may include a housing having a plurality of facets, each of the plurality of facets having a shape that is a portion of separate ellipses sharing a common focus. First and second surfaces are defined by first and second planes intersecting along a line within a volume of the body. A light source is positioned near the first surface, at the common focus, and is angularly oriented thereto such that light emitted by the light source is directed into the housing, reflected by at least one of the plurality of facets, and exits the light reflector out of either the first plane or the second plane. The body of the light reflector may include a free-form surface that is generated as the best fit to the plurality of facets.

摘要： An illumination system, useful for generating illumination light in an image-projection system, has at least a first image-forming panel. A first array of light emitting elements, for example light emitting diodes (LEDs), generates a first light beam associated with a first wavelength range. A second array of light emitting elements generates a second light beam associated with a second wavelength range. The second array of light emitting elements comprises at least a first light emitting element generating light in the second wavelength range and a second light emitting element generating light in the first wavelength range. The center wavelength of the second light emitting element may be closer in value to the center wavelength of a light emitting element in the first array than to the center wavelength of the first light emitting element.
