Optical system with mixed structure of lens and reflector

An optical system of a lens and reflector mixed structure belongs to the technical field of non-imaging optical design, and mainly comprises a dodging collimating lens, a conical surface emitter and a free-form surface reflector to form a refraction and reflection mixed structure, the dodging collimating lens is used for concentrating light emitted by an LED light source and adjusting the light into parallel light, and the conical surface emitter is used for emitting light to the free-form surface reflector. The conical surface emitter and the free-form surface reflector are used for reflecting parallel light rays and re-diffusing and re-distributing the parallel light rays, meanwhile, glare generated by the high-power LED light source is reduced, and the optical system can form uniform circular light spots at a target position. The LED optical system is matched with one another in system structure, light emitted by the LED light source can be refracted, reflected and the like through the lens and the reflect
