Abstract:
A projector and its illumination system and wavelength conversion device are provided. The wavelength conversion device includes a substrate, a wavelength converting portion, and a wavelength maintaining portion. The substrate has a rotation axis. The wavelength converting portion surrounds the rotation axis and is adapted to receive the first beam and convert a first portion of the first beam into a second beam. The wavelength maintaining portion surrounds the rotation axis and is adapted to receive the first beam and guide a second portion of the first beam. A ratio of the first portion of the first beam with respect to the first beam is greater than a ratio of the second portion of the first beam with respect to the first beam. The illumination system and the wavelength conversion device in the projector reduce the number of optical elements, thereby reducing the cost and the size of the projector.

Claim (Index 18):
An illumination system, comprising:\n a light source device, adapted to provide a first beam; a wavelength conversion device, disposed on a transmission path of the first beam, wherein the wavelength conversion device comprises:\n a substrate, having a rotation axis; \n a wavelength converting portion, surrounding the rotation axis of the substrate, adapted to receive the first beam, and adapted to convert a first portion of the first beam into a second beam; and \n a wavelength maintaining portion, surrounding the rotation axis of the substrate, adapted to receive the first beam, and adapted to guide a second portion of the first beam, wherein a ratio of the first portion of the first beam with respect to the first beam is greater than a ratio of the second portion of the first beam with respect to the first beam; and \n a light combining element, disposed on the transmission path of the first beam between the light source device and the wavelength conversion device, wherein the first beam emitted from the light source device is transmitted to the wavelength conversion device by the light combining element, the light combining element is disposed on a transmission path of the second beam from the wavelength converting portion and the second portion of the first beam from the wavelength maintaining portion and adapted to combine the second portion of the first beam and the second beam.
