    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.
