Projector and illumination system
Abstract:
A projector includes an illumination system, a light valve, and a lens. The illumination system includes a scanning light source assembly and a wavelength conversion device. The scanning light source assembly provides an excitation beam. The excitation beam scans in a plurality of scanning directions. The wavelength conversion device is disposed on a transmission path of the excitation beam. The excitation beam scans the wavelength conversion device in the scanning directions in a plurality of time intervals respectively, and the excitation beam is converted into a color beam by the wavelength conversion device in one of the time intervals. The light valve is disposed on a transmission path of an illumination beam and converts the illumination beam into an image beam, wherein the illumination beam includes the color beam. The lens is disposed on a transmission path of the image beam.
