PROJECTOR APPARATUS WITH MULTI-LIGHT SOURCES AND LIGHT COUPLING MODULE THEREOF

摘要

PROBLEM TO BE SOLVED: To exhibit the maximum effects of the light coupling of twin lamps for a DLP projector, and to prolong the life of a light source.;SOLUTION: A projector apparatus with multi-light sources and a light coupling module thereof are disclosed. The projector with multi-light sources comprises a light incident area, a light tunnel, a color wheel, a light coupling module and a plurality of light sources, all disposed in the light incident area. The light coupling module comprises a light coupling device, a light gathering device, and a reflection device. The light sources provide a plurality of light beams, which are substantially coupled into a single light beam by the light coupling device, thereafter, the single light beam travels through the color wheel and the light tunnel through the light gathering device and the light reflection device.;COPYRIGHT: (C)2008,JPO&INPIT
