摘要： High pressure mercury arc lamps are commonly used as the illumination source in many projection systems. Such lamps may be deficient in either output power or spectrum, and so it is desirable to combine the light from the lamp with light from a second light generator. The second light generator may be another mercury lamp or a solid state source, such as one or more light emitting diodes. Different ways of combining light from two light generators are described. The second light source may be an arrangement of a number of red LEDs that supplements the red light produced by the mercury light. A tunnel integrator may be used to homogenize the combined light beam and to reduce the angular separation between the light beams from the two light generators.

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.

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： 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.

The prism includes first (19) and second (21) spaced part surfaces which are oriented such that: (a) light from a light source (33) will pass through the spaced apart surfaces to the digital light panel; (b) light from “on” pixels will undergo total internal reflection at the second surface (21) and be directed into the acceptance angle of a projection lens (39); and (c) light from “off” pixels which reflects from the second surface will be directed away from the lens' acceptance angle.
