Abstract
A laser light source includes a laser light source module, a light converging module, first and second lens sets, a color wheel, and a light tunnel. The laser light source module emits a first light. When passing the light converging module, the first light converges in a second direction perpendicular to the travel direction of the first light and does not converge in a third direction perpendicular to the second direction and the travel direction. The first light becomes a parallel beam after passing the light converging module. Then, the first light enters the first lens set. The color wheel receives the first light passing the first lens set, partially transforms the first light into a second light, and partially reflects the first light. Then, the first and second light pass the first and second lens sets. Then, the light tunnel collects the first and second light.
