Background

Light therapy (light therapy) is a method of preventing and treating diseases and promoting the recovery of the body by using sunlight or artificial light (infrared rays, ultraviolet rays, visible light, laser light). The light therapy in physiotherapy is artificial light radiation, and the infrared band light radiation is one of the light therapies. The changes obtained by the infrared warming effect mainly include the temperature rise on the skin surface, the improvement of the subcutaneous blood circulation dynamics, the relaxation of muscle tension, the alleviation of pain, the regulation of the normalization of autonomic nerves, and the like. Tungsten halogen lamps are used as radiation sources, the spectral range of the radiation generally covering the visible and near infrared bands. Since the wider the spectral range, the higher the heat radiation energy of the phototherapy device, the skin temperature to be irradiated will be above 46 ℃ and will cause scald and cause tissue damage such as blister. Because the wavelength range of the halogen tungsten lamp is 680 nm-3000 nm, certain risks can be brought if the irradiation intensity is not well mastered in the use process of the halogen tungsten lamp; meanwhile, the phototherapy equipment has a small working distance, so that the flexibility is poor and the use is inconvenient.
