摘要： 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.

摘要： A lighting device (100) and a projection device, comprising a light source for generating a blue excitation light (110), a base board (130), and a wavelength conversion material layer (140) covered on the base board (130). The wavelength conversion material layer (140) absorbs a part of the blue excitation light and emits an excited light. The color coordinate of the excited light is within the pre-configured color area, so that a mixed light combined by the excited light and the remaining blue excitation light not absorbed by the wavelength conversion material layer (140) exits the wavelength conversion material layer (140). The color coordinate of the mixed light is closer to the pre-set blue light color coordinate than the color coordinate of the blue excitation light.

摘要： 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.
