Abstract: 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.

Abstract: A light source system using an excitation light source and a multi-segmented color wheel device with wavelength conversion materials is disclosed. The color wheel device includes a first area having two or more first segments and a second area having two or more second segments for receiving the excitation light. The color wheel device is driven by the driving device periodically, so that a first light sequence is generated by the two or more first segments in the first working mode and a second light sequence is generated by the two or more second segments in the second working mode. The first light sequence is different from the second light sequence. The first and second working modes are switched by a switching device. The light source system may be used in image projection system generating two or more different lights sequences in different working modes.

Abstract: 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.
