摘要： A light source comprising an excitation light source 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 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 for collecting converted light originating from the optical wavelength conversion material. To separate the paths of the converted 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 converted light through the optical-guiding member.

摘要： A solid state light source device for generating a constant broad band light useful in multiple SLM projectors. The light source device includes a blue or UV/near UV excitation light and a moving plate carrying wavelength conversion materials to convert the excitation light into a broad band light. The wavelength conversion materials include red, green, yellow and/or blue phosphors, and may pass some of the blue excitation light. The broad band light outputted by the phosphor plate includes at least two primary color components and has a constant intensity and spectrum as a function of time. The solid state light source device further includes a second light source such as a blue light source, and a light combination device which combines the output light of the moving phosphor plate and the light from the second light source into one beam of constant, broad band light.

摘要： A light source system and a projection system employing the same. The light source system includes a light source emitting an excitation light, a moving device carrying a wavelength conversion material and an adjustment device. The excitation light irradiates on the wavelength conversion material. When the moving device is in a periodical moving state, the light spot position irradiated by the excitation light on the moving device moves following a first working track. The adjustment device is used for adjusting the light spot position irradiated by the adjusted excitation light on the moving device so that it moves following a second working track. The first working track is separated from the second working track. The system can reduce the working load of the wavelength conversion material on the first working track, thus slowing the aging of the wavelength conversion material, and improving the life of the light source system.

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.

摘要： A light source device includes a LED light source or a wavelength conversion material having a near Lambertian light emitting surface. The light source device includes a light recycling system to reflect small-angle lights (lights closer to the normal direction of the light emitting surface) back to the light source, and a collection system for collecting and outputting large-angle lights (lights farther away from the normal direction). The lights reflected by the light recycling system is scattered by the emitting surface in all directions, where the large-angle scattered lights are collected by the light collection system and the small-angle scattered light is reflected by the light recycling system again. A second excitation light source without wavelength conversion material or a second light source with its own wavelength conversion material may be provided, and the second light is directed to the light emitting surface by appropriate optical components.
