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： 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： 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 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 light combiners include arrangements of four polarizing beam splitters, such that three different wavelength spectrums of light can be directed into three of the polarizing beam splitters, and a combined light can be received from the fourth polarizing beam splitter. The light splitters can be the same configuration as the light combiners, but the direction of light travel is reversed to split, rather than combine, light. Polychromatic light can be directed into one of the polarizing beam splitters, and light having three different wavelength spectrums can be received from the other three polarizing beam splitters. The three different wavelength spectrums of light, the combined light, and the polychromatic light can be unpolarized light. The light combiners can be useful as unpolarized white light sources, such as in digital micro-mirror display projection systems.

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.
