Abstract:
A projector includes a light source module, an optical engine, a light valve and a projecting lens. The light source module includes light sources, optical fibers and a light integration rod. Each of the light sources provides an illumination sub-beam. Each of the illumination sub-beams transmits to the light integration rod through the corresponding optical fiber, and passes through the light integration rod and emits out to form a first illumination beam. The optical engine includes a phosphor wheel located at a transmission path of the first illumination beam and converting the first illumination beam into a second illumination beam. The light valve is located at a transmission path of the second illumination beam and converts the second illumination beam into an image beam. The projecting lens is located at a transmission path of the image beam and projects the image beam out of the projector.
