    摘要: The present invention provides a method, system and structure for maintaining light characteristics from a multi-chip LED package. This may be done by selecting a desired light output and restricting light from a plurality of light emitting diodes in the multi-chip LED package. It may also be done by measuring the restricted light, comparing the measured output light to the desired light and by adjusting current to LEDs in the multi-chip LED package based on the measured light.

    摘要: A storage compartment is equipped with a light emitting diode (LED) light source for illuminating contents inside the compartment. The LED light source includes a LED light engine outside the compartment and a light guide inside the compartment. The light guide is optically coupled to be LED light engine to bring light from the LED light engine into the compartment for providing illumination inside the compartment. The LED light engine may include red, green, and blue LEDs that contribute to the illumination inside the compartment. Respective outputs of the red, green, and blue LEDs may be separately controllable to allow a variably controlled color point of illumination inside the compartment. Total output of the LED light engine may be controllable to vary intensity of illumination inside the compartment.

    摘要: An image processing system includes a combined display-camera having an array of interspersed display elements and camera elements, arranged substantially in a common plane of a flat panel or other display. Each of at least a subset of the camera elements has one or more imaging angles associated therewith, with the one or more imaging angles being selected to provide a desired imaging operation for the combined display-camera. The imaging angles of the camera elements can be selected to provide an imaging operation which approximates that of a lens-based single-camera system, a pin-hole camera system or other type of system. Each of the camera elements may include multiple image sensors, such that different imaging angles can be set for the different image sensors of a given camera element, and different perspectives of a scene can be generated in the image processing system.

    摘要: A faceted surface has first and second facets which deflect respective first and second light beams to produce first sub-beams which alternate with second sub-beams. The faceted surface may be a reflector having first facets at 120° to second facets for mixing light beams which are incident at 120° to each other. 100% of reflected sub-beams from each source alternate with 100% of sub-beams from the other source. The faceted surface may also be a refractor which is part of a transparent block having two parallel faceted surfaces. A first refractive surface refracts parallel light beams to produce diverging beams which are each split into spaced apart sub-beams by the second refractive surface. 50% of refracted sub-beams originating from each source alternate with 50% of refracted sub-beams of each adjacent source.

    摘要: According to this invention, a side-emitting illumination device for uniformly distributing light is composed of an LED light source, a light-transmitting rod which permits total internal reflection, and outcoupling material affixed to an outer surface of the rod. Light enters the rod at one end and travels along the rod by total internal reflection. Light that hits the outcoupling material is angularly distributed based on the width of the outcoupling material.

    摘要: A lens array for a lamp directs light to a light conduit such as an optical fiber or light pipe for guiding light to a remote location. An array of LED serve as light sources. The lens array includes an integrally formed member having a number of collimator lenses positioned in the lens array so that each lens can operate as a collimator for a corresponding LED to produce a respective collimated beam of light. The lenses have optical properties that are optimized according to where their corresponding LED are positioned in the LED array, so that the lens array is provided with lens prescriptions that produce refraction of the collimated beams of light toward an entrance aperture of the light conduit.

    摘要: Apparatus for mixing light from discrete LED light sources utilizes beam splitters which each have a semi-reflective layer which partially transmits and partially reflects light of any wavelength incident thereon. Each semi-reflective layer is situated in a transparent prismatic black between reflective surfaces on parallel outside faces of the block so that two parallel input beams are mixed and transmitted as two parallel mixed beams of like color. For a square array of light sources, a first mixing stage consists of two such prismatic blocks arranged side-by-side, and a second mixing stage consists of two such prismatic blocks arranged side-by-side and rotated 90 degrees to the first stage. The second stage is arranged to receive a square array of mixed beams and produces four identical output beams. The colors of the light sources are chosen so that all output beams are white.
