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-emitting device and a related projection system. Light-emitting devices (300, 400) comprise: a light source unit (1) and focusing lenses (330, 430). The light source unit (1) comprises laser units (310, 410) and collimating lenses (320, 420) corresponding to the laser units (310, 410). The light-emitting surface of the laser units (310, 410) is a rectangle, and the light divergence angle of laser passing through the cross-section of the long side of the rectangle is smaller than the light divergence angle of same passing through the cross-section of the short side of the rectangle. The collimating lenses (320, 420) are used for focusing the laser from the laser units (310, 410) on a target surface to form a predetermined light spot. The laser units (310, 410) are located on the light axis of the collimating lenses (320, 420) in a predetermined position deviating from the focal point thereof, so that the predetermined light spot has a predetermined length-width ratio. The light-emitting device and the related projection system have the advantages of relatively small regulation quantity and relatively high assembly efficiency.

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.
