摘要： 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.

摘要： An illumination system, including a light source module, a phosphor wheel, a light recycling element, and a light uniformizing element, is provided. The light source module emits an excitation light beam. The phosphor wheel includes a phosphor region. At a second timing, the other part of the excitation light beam transmitted to the phosphor region forms an unconverted light beam and is transmitted to the light recycling element, and is reflected by the light recycling element to form a recycled light beam. A part of the recycled light beam is converted into a second converted light beam. A first converted light beam and the second converted light beam are transmitted to the light uniformizing element through a same path, so that the illumination system outputs second light in the illumination light beam. A projection apparatus is also provided.

摘要： 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.
