Patent ID: 7126652

Claim:
A light source device, comprising: a first light source for emitting a first light; a second light source for emitting a second light; a third light source for emitting a third light; a first reflector disposed at the first light source; a second reflector disposed at the second light source; a third reflector disposed at the third light source; a first polarization converter for obtaining a first polarized light from the first light, the first polarization converter including a first polarizer through which the first polarized light is obtained and utilizing a first reflection light reflected by the first polarizer and the first reflector so as to obtain the first polarized light; a second polarization converter for obtaining a second polarized light from the second light, the second polarization converter including a second polarizer through which the second polarized light is obtained and utilizing a second reflection light reflected by the second polarizer and the second reflector so as to obtain the second polarized light; a third polarization converter for obtaining a third polarized light from the third light, the third polarization converter including a third polarizer through which the third polarized light is obtained and utilizing a third reflection light reflected by the third polarizer and the third reflector so as to obtain the third polarized light; and a color synthesizing optical system for synthesizing the first polarized light, the second polarized light and the third polarized light.
