    • A light source system and a projection system applied thereby. The light source system includes a light source (10) emitting excitation light, a moving device (20) provided with an optical wavelength conversion material and an adjustment device (30). The excitation light irradiates on the optical wavelength conversion material. When the moving device (20) is in a periodical moving state, the light spot position irradiated by the excitation light on the moving device (20) moves following a first working track. The adjustment device (30) is used for adjusting the light spot position so that the light spot position irradiated by the adjusted excitation light on the moving device (20) moves following a second working track. The first working track is separated from the second working track. The present invention can reduce the working load of the optical wavelength conversion material on the first working track, thus slowing the aging speed of the optical wavelength conversion material, and improving the service light of the light source system.

    • A light source comprising an excitation light source (110) for providing excitation light, and an optical wavelength conversion member disposed at a distance from the excitation light source. The optical wavelength conversion member comprises an optical wavelength conversion material (150) for converting the excitation light into stimulated light. The light source also comprises an optical-guiding member that allows the excitation light to be incident on the optical wavelength conversion material, and an optical-collecting member (130A) for collecting stimulated light originating from the optical wavelength conversion material. To separate the paths of the stimulated light and the excitation light, the etendue of the optical-guiding member is less than or equal to ¼ of the etendue of the optical-collecting member. This allows the optical-guiding member to draw in the excitation light while preventing the excessive escape of the stimulated light through the optical-guiding member. The advantages of the light source are that it can separate the paths of the excitation light and the stimulated light, the light path is simple, and the optical members are easy to manufacture.
    • 一种光源,包括用于提供激发光的激发光源(110)和与激发光源一定距离设置的光波长转换部件。 光波长转换构件包括用于将激发光转换成受激光的光波长转换材料(150)。 光源还包括允许激发光入射到光波长转换材料上的光学引导部件和用于收集源自光波长转换材料的受激光的光学收集部件(130A)。 为了分离受激光和激发光的路径,光导元件的光密度小于或等于光收集元件的光密度的1/4。 这允许光引导构件在激发光下吸引,同时防止被激发的光通过光导构件的过度逸出。 光源的优点在于它可以分离激发光和受激光的路径,光路简单,并且光学元件易于制造。
