摘要： Disclosed are a light source system (30) and an image projection system including the light source system. The light source system comprises a light source (31) used for generating a excitation light, a moving color device (34) used for receiving the excitation light which has a first area (41) and a second area (42) with at least two segments respectively, a driving device (34) used for driving the moving color wheel 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. Thus two or more different lights sequences in different working modes are generated.

摘要： The invention concerns a light emitting device and a projection system adopting same. The light emitting device (100) comprises a coherent source (110), a diffusing element (120), and a light guide part (140). The coherent source (110) is used for generating coherent light. The diffusing element (120) includes a first surface (121) and a second surface (122) which are opposite to each other, and the diffusing element (120) is used for dispersing the coherent light coming from the coherent source (110) so as to generate incoherent light. The light guide part (140) is provided on the side of the first surface (121) of the diffusing element (120). The light guide part (140) is used for guiding the coherent light emitting from the coherent source (110) to be incident on the first surface (121) so as to form a first light path, guiding a part of incoherent light emitting from the first surface (121) to emit through the first light path, guiding the remaining incoherent light to emit through a second path, and separating the first path and the second path. The luminous flux of the incoherent light emitting through the first light path is less than that of the incoherent light emitting through the second light path.

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.

摘要： An illumination devices using excitation light and a wavelength conversion material to generated converted light for illumination, where the wavelength conversion material is excited by multiple excitation lights from both sides to achieve increased brightness. The excitation lights incident on the two sides of the wavelength conversion material may have the same color or different colors. Light separation structures are provided on both sides of the wavelength conversion material to separate the excitation light and the converted light. Light separation may be based on color difference or etendue difference of the excitation light and converted light. In one particular example, wavelength conversion material is formed on a surface of an LED which acts as the first excitation light source, and a second excitation light is delivered through a light separation structure onto the other side of the wavelength conversion material.
