摘要： An LED illumination unit uses a first reflector (204) comprising a reflecting surface (210) formed as a surface of revolution about a first revolution axis (212). The LED (202) emits light about a first LED axis (208) towards the reflecting surface (210) of the first reflector (204). The first LED axis (208) is non-parallel to the first revolution axis (212) and the light emitting area of the first LED unit (202) is positioned substantially at a focus of the reflecting surface (210). The reflector (204) may also have two or more reflecting surfaces for collecting and directing light from two or more respective LEDs.

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. Unpolarized 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： Illumination systems are disclosed that include a light source or a bank of light sources having a non-radially symmetrical aperture having a longer dimension and a shorter dimension, such that the light source or bank of light sources produces illumination with a non-radially symmetrical angular intensity distribution having a larger angular dimension and a smaller angular dimension. The illumination systems include an integrator having an entrance end optically connected to the bank of light sources, an exit end, and a dimension that experiences a larger increase from the entrance end to the exit end. The integrator is disposed so that the dimension experiencing the larger increase is substantially aligned with the larger angular dimension of the illumination produced at the entrance end of the integrator.

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： A projection display system employs one or more color modifying aperture stops, such as apodizing aperture stops, to provide high contrast, balanced color and high throughput. One projection system includes a reflective liquid crystal-on-silicon light valve positioned with a polarizing beam splitter, such as a wire grid polarizing beam splitter, for each of the primary color component light paths to separately impart image information into each of the primary color components of light. A color combiner receives and combines the primary color components of light with imparted image information to provide light representing a polychromatic display image. At least one aperture stop is positioned along at least one of the primary color component light paths to balance relative intensities of the primary color components of light.

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.
