一种激光光源及投影显示装置
摘要：
本发明公开了一种激光光源及投影显示装置。其激光光源包括：N组激光器，N个凸透镜，至少一个反射镜单元，和一个凹透镜；每个凸透镜对应一组激光器，用于会聚对应的一组激光器发出的光束；每个反射镜单元至少对应一个凸透镜，设置于对应的凸透镜的出射光方向，所述凹透镜设置于所述至少一个反射镜单元的出射光方向；每个反射镜单元对应的各个凸透镜出射的光束经过该反射镜单元后到达所述凹透镜。本发明实施例提供的结构，减少了各个光学器件之间的距离，从而有效减少了激光光源的体积，解决了目前激光光源及使用该激光光源的产品(例如投影机)体积偏大的问题，进而降低了生产成本。
摘要（英）：

The present disclosure relates to a laser light source and a projection display device. The laser light source includes: N groups of laser devices, N convex lenses, a concave lens and at least one reflector component; each convex lens corresponds to a group of laser devices, and is configured to converge light beams emitted by the corresponding group of laser devices; each reflector component corresponds to at least one convex lens and is disposed in a emergent light direction of a corresponding convex lens, and the concave lens is disposed in a emergent light direction of the at least one reflector component; and an emergent light beam of the convex lens corresponding to each reflector component passes through the reflector component and then arrives at the concave lens.
