Abstract
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 region, a light tunnel, a color wheel, a light coupling module, and a plurality of light sources, all disposed in the light incident region. 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. The single light beam travels through the color wheel and the light tunnel through the light gathering device and light reflection device.
