摘要： An illuminating module includes two spaced-apart light sources, two hemispherical reflectors, two parabolic reflectors and two planar reflectors. Each of the light sources is disposed at a common focal point of one of the hemispherical reflectors and one of the parabolic reflectors. Each of the parabolic reflectors faces a respective one of the hemispherical reflectors in one direction, and confronts a respective one of the planar reflectors in the other direction such that light rays from each of the light sources which radiate toward the respective hemispherical reflector and the respective parabolic reflector are directed to the respective planar reflector so as to be subsequently reflected to travel in parallel lines parallel to an optical axis.

摘要： A projection display includes a light source for generating a beam output that contains first, second and third color components, a color separation/synthesizing prism unit having a color separation part for separating the beam output from the light source into the first, second and third color components that exit the prism unit in three different directions, and first, second and third light modulators for modulating the first, second and third color components that exit from the color separation part. The prism unit further has a color synthesizing part that receives the modulated first, second and third color components from the light modulators and that synthesizes the modulated first, second and third color components so as to form an output beam. A projection lens receives the output beam from the color synthesizing part, and is used to project a color image. The first, second and third color components have equal optical path lengths measured from the light source to the respective light modulator. The first, second and third color components further have equal optical path lengths measured from the respective light-modulator to the projection lens.
