Abstract: A three-dimensional imaging system uses a single primary optical lens along with three non-collinear apertures to obtain three offset optical channels each of which can be separately captured with an optical sensor.

Abstract: An illuminator with blue and red LEDs, a reflector upstream of the LEDs for capturing upstream light emitted out of the back surfaces of the LEDs and redirecting downstream as useful illumination, a band pass filter for conditioning the downstream light, a phosphor layer for changing the spectral properties of light from the LEDs, and a non-imaging concentrator for creating a beam of illumination over a predetermined solid angle, uniformity, and spectral content.

Abstract: The present invention generally relates to video and/or television projection systems, and more particularly, to LED based light source systems utilizing generally non-rotationally symmetric, preferably oblong or rectangular, non-imaging collection optics for providing improved projection systems relative to arc lamp and other LED based light source systems. The non-rotationally symmetric non-imaging collection optics are configured to operate with LEDs to provide preferred, generally, uniform light distributions whose étendues match those of downstream applications such as those encountered in projection systems. Also provided are various arrangements for coupling LED output to the entrance aperture of collection optics and for coupling the outputs from a plurality of collection optic outputs to form single beams of illumination of preferred patterns, intensities, and color.

Abstract: The invention provides an LED lighting device and method that produces high intensity, spatially uniform, white light in the near and far fields in a reduced package size that does not significantly heat the surrounding environment, wherein the white light is produced by using a phosphor layer in conjunction with a single LED.

Abstract: A surgical lighting system including overhead surgical lights having integrating cavities which capture metal halide arc lamp optical energy and output spatially uniform optical energy to reflectors which direct the optic energy to a common surgical illumination region, a surgical light port system having illuminating ports, and a thermal dissipater. The surgical lighting system includes power back-up systems and light sources with multiple lamps that are automatically sequenced to provide constant surgical illumination.

Abstract: A scanning light source system combines the outputs from multiple, spatially separated, sequentially pulsed light sources for travel in rapid succession along one or more common delivery paths to provide one or more collective outputs that are comparatively higher than would otherwise be possible with the light sources operating singly.

Abstract: An illumination system for illuminating an area within a room includes one or more light sources, preferably disposed outside the room, one or more lighting heads disposed within the room, one or more light pipes and/or fiber bundles to transmit light from the source(s) to the lighting head(s). The system includes means for controlling both the intensity and the color rendering index of the light emitted from the lighting head. In a preferred embodiment, the sources include an incandescent source extending across the visible spectrum and a light emitting diode source which emits essentially red light, and control of the color rendering index is effected by controlling the relative amounts of light from the two sources reaching the lighting head. Preferred forms of the invention also include special joints which permit all necessary translations and rotations of the lighting head while still permitting a continuous light path via fiber bundles and/or light pipes from the source to the lighting head.
