The current trend is that semiconductor laser therapy is moving towards more personalized and precise treatment.

[0003] The treatment principle of semiconductor lasers of different wavelengths mainly depends on their ability to interact with biological tissues. In medicine, ultraviolet light bands are used for disinfection or treatment of pigmented skin diseases, infrared light bands are used for rehabilitation of skin and subcutaneous tissue and wound healing, red light bands are used for anti-inflammatory, swelling and pain relief or to promote human metabolism and whiten and rejuvenate the skin, yellow light bands are used to treat chloasma and allergic skin diseases, and blue light bands are used for sterilization and regulation of the immune system. This type of visible or invisible light has been widely used in skin rehabilitation treatment and medical cosmetology, but when this type of light source is working, there is a risk of irradiated light leakage, which, if not handled properly, will cause adverse effects such as photochemical pollution to patients or the treatment environment. Summary of the invention
