The incident direction of the laser beam is perpendicular to the surface of the fluorescent powder sheet 212, so that the size of a light spot can be reduced, the potential safety hazard caused by leakage when light is projected to the outer side of the fluorescent powder sheet 212 is avoided, and meanwhile, the brightness of high beam can be improved.
