摘要:
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.
