Beschreibung
Zusammenfassung:	The utility model relates to a uniform illumination laser light source which comprises a driving power source and a laser, and further comprises an optical diffusion sheet and a lens, wherein the optical diffusion sheet is used for scattering the light emitted by the laser, and the lens is used for controlling the angle of the emitted light. The laser is driven by the driving power source to emit the light, then the light is scattered by the optical diffusion sheet so as to enable uneven rectangular light spots emitted by the semiconductor laser to be changed into even circular light spots, the angle of the emitted light is controlled by adjusting the front and back positions of the lens, and the field angle of the emitted light can be matched with that of a pick-up lens to meet the requirements for lighting of different emitting distances (10-100m).
