Illuminating apparatus using multiple light sources

摘要

An illuminating apparatus includes a plurality of light members spaced apart from each other and operable so as to produce forwardly directed parallel light rays, a parabolic reflector disposed in front of the light members for receiving the forwardly directed parallel light rays from the light members, and an integrator unit. The parabolic reflector has a reflecting surface that confronts the light members. The integrator unit has an input side to receive the light rays reflected by the reflecting surface of the parabolic reflector.
