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.

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

摘要： The present invention relates to an optical system for providing uniform illumination of a light valve. The light source is an extended source generally emitting a non-uniform spatial distribution of light power. Source light is focused into the entrance end of a light transmitting tunnel having reflecting interior wall surfaces and having cross sectional and length dimensions chosen to deliver, at the exit end of the tunnel, light which is substantially uniform in power distribution over the surface area of the exit end. This is caused by multiple reflections from the tunnel walls. The exiting light is advantageously used to illuminate uniformly a light valve. The tunnel may be tapered to alter the exit angular aperture. The tunnel may be hollow or filled with a transparent material. In addition, the tunnel may be segmented and folded to provide a joint which conforms tunnel geometry to given spatial limitations between source and valve. The joint also provides a convenient way of directing heat out of the tunnel structure. One embodiment of the present invention includes a compound light transmitting tunnel with a plurality of segments and exit ends. A joint between adjacent segments divides light into a transmitted range of wavelengths and a reflected range of wavelengths.

摘要： A projection engine is disclosed, in which white light from a uniform telecentric source is collimated, polarized, and split into red and cyan beams. The collimated red light passes through a red focuser, which has an off-axis, front-surface mirror that has an aspheric and/or conic profile, and a spherical lens. The collimated cyan light passes through a similar cyan focuser, after which it is split into blue and green beams. The mirror reflective surface has an aspherical shape to minimize aberrations at the edge of the field of view in the illumination optical path. The collimator is at the front focal plane of each focuser, making the emergent converging beam telecentric, and a pixelated panel is at the rear focal plane of each focuser. The reflected light beams from the red, green and blue pixelated panels are superimposed on a pixel-by-pixel basis and are directed to a projection lens.
