US 2014/0192328 A1 · ILLUMINATION SYSTEM FOR STEREOSCOPIC PROJECTION DEVICE

Abstract

An illumination system for a stereoscopic projection device is provided. The illumination system comprises a luminous element and a color wheel module. The luminous element is adapted to generate a plurality of first wave band lights when the color wheel module has a plurality of wave band transmitting transforming areas and a plurality of wave band reflecting transforming areas. When the first wave band lights are projected to the wave band transmitting transforming areas, the first wave band lights are adapted to transmit the wave band transmitting transforming areas to excite a plurality of first selected wave band lights. When the first wave band lights are projected to the wave band reflecting transforming areas, the wave band reflecting transforming areas are adapted to excite and reflect a plurality of second selected wave band lights.

Dependent claims

An illumination system for a stereoscopic projection device, comprising:

a luminous element generating a plurality of first wave band lights;
and
a color wheel module having a rotating disk, a plurality of wave band transmitting transforming areas and a plurality of wave band reflecting transforming areas which are formed on the rotating disk;
wherein when the first wave band lights are projected to the wave band transmitting transforming areas, the first wave band lights transmit the wave band transmitting transforming areas to excite a plurality of first selected wave band lights different from the first wave band lights, and when the first wave band lights are projected to the wave band reflecting transforming areas, a plurality of second selected wave band lights different from the first wave band lights and the first selected wave band lights are excited and reflected from the wave band reflecting transforming areas.
