Phototherapy - light irradiation therapy

     Phototherapy is the use of photobiological effect, with a specific wavelength of light to human skin or some tissue cells to promote growth or inhibit growth, to achieve the purpose of treatment.
     At present, phototherapy has been attached great importance to by medical institutions. The medical community, the biological community and the optical community are studying the treatment mechanism and treatment methods in a multidisciplinary linkage including pathology, photochemistry, photobiology and physics. There have been continuous literature reports on the clinical efficacy of LED phototherapy, and the efficacy of LED phototherapy is becoming prominent.
     Compared with the traditional light source, LED is more in line with the special requirements of light source for phototherapy, which are: the light wavelength selection range should be wide, the amount of radiation. The radiation spot should be controllable and adjustable, the light is pure, there is no harmful spectral component, and the electrical safety, etc., because the LED has the above characteristics, meet the above requirements, it will become the first choice of health light source to replace the traditional phototherapy light source.
     Phototherapy as an effective clinical treatment method, LED has been widely used in this field.
     Phototherapy is the use of biological tissue to absorb different wavelengths of light energy, and convert it into heat and chemical energy, resulting in a series of chemical reactions in the body, to achieve the required different effects.
