A projector includes a projection lens set, a DMD, a prism unit, a light guide unit, and a light source device. The light source device includes a first and a second LEDs, a laser light source, and a color wheel. The first LED is positioned in a first optical path and generates a first light. The laser light source is positioned in a second optical path and generates a laser light. The second LED is positioned in a third optical path and generates a second light. The laser light irradiates the color wheel to generate a third light. A light merging unit merges the first, second, and third lights. The light guide unit guides the mixed light to the prism unit. The mixed light is refracted to the DMD via the prism unit. The refracted mixed light is reflected to the projection lens set via the DMD.
