Patent ID: 6847412

Claim:
An illumination system in a liquid crystal projector, comprising: a light source including an arc lamp emitting beams of light by arc light emission and a parabolic reflector for making total reflection of the beams from the arc lamp to direct the beams in one direction; a first fly eye lens including an n×m matrix of lens cells which are for imaging the beams incident from the light source on various points spaced apart from one another, wherein each lens cell of the first fly eye lens is a micro-lens, wherein the first fly eye lens has a first plurality of lens cells each with an optical axis offset relative to a center point of the lens cell in order to compensate for a shape of the arc lamp; and a second fly eye lens refracting the beams from the first fly eye lens into parallel beams, wherein the first fly eye lens comprises a plurality of lens cells corresponding to a plurality of n×m lens cells of the second fly eye lens, respectively, and wherein n and m are integers greater than 2.
