US Patent 7437039 Optical engine with tightly coupled light source

An image presentation device (100) with an associated optical light engine includes one or more semiconductor light emitting diodes or other such devices (122, 124, 126) that are combined to provide a source of light to a micro-display panel (150). Light integrators (128), preferably shaped to correspond to the shape of the light emitting devices, are located such that a portion of each terminal is positioned adjacent to or in direct contact with the light emitting surface of the semiconductor dies.
