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 34):
The illumination system according to  claim 18 , further comprising a reflective element group, wherein the reflective element group is disposed on a transmission path of the second portion of the first beam, the light combining element comprises a light transmitting portion adjacent to the light source device and a first dichroic portion adjacent to the wavelength conversion device, the wavelength conversion device further comprises a second dichroic portion disposed on the second surface of the substrate, the first beam emitted from the light source device passes through the light transmitting portion and the first dichroic portion and is transmitted to the wavelength conversion device, the second beam from the wavelength converting portion is reflected by the first dichroic portion to the light combining element, the second portion of the first beam from the wavelength maintaining portion passes through the second dichroic portion and is transmitted to the reflective element group, the reflective element group reflects the second portion of the first beam to the light combining element, and the second portion of the first beam passes through the light transmitting portion and the first dichroic portion.
