  • Illumination system comprising a rotation wheel with transmissive and reflective regions and a phosphor used for converting a light beam of a first color from the reflective or transmissive region to a second color and projection apparatus
    Patent number: 9033518
    Abstract: An illumination system includes a first light source, a first rotation wheel, a first phosphor element, and a light combining element. The first light source is capable of emitting a first color beam. The first rotation wheel is disposed on a transmission path of the first color beam and includes a first transmissive region and a first reflective region. The first transmissive region is capable of allowing the first color beam to pass through so as to form a first color transmissive beam. The first reflective region is capable of reflecting the first color beam to form a first color reflective beam. One of the first color transmissive and reflective beams excites the first phosphor element to form a second color beam. The light combining element combines the second color beam and a beam originating from the other one of the first color transmissive and reflective beams.

  • LIGHT SOURCE MODULE AND PROJECTION APPARATUS
    Publication number: 20130088689
    Abstract: A light source module including a first light-emitting device, a light emitting wheel, a second light-emitting device, and a light combination device is provided. The first light-emitting device provides an exciting beam. The light emitting wheel is disposed on a transmission path of the exciting beam and has a first light conversion area. The exciting beam obliquely irradiates on the first light conversion area and is converted into a first color beam. The second light-emitting device provides a second color beam. Herein, colors of the first color beam and the second color beam are different. The light combination device is disposed on the transmission paths of the first color beam and the second color beam. The first color beam is reflected to the light combination device by the light emitting wheel and the light combination device combines the first color beam and the second color beam.
