Ultraviolet rays are divided into long wavelength ultraviolet rays (UVA: 320-400 nm), medium ultraviolet rays (UVA: 280-320 nm) and short wavelength ultraviolet rays (UVC: 200-280 nm), and short wavelength ultraviolet rays But it is widely known that the long wavelength ultraviolet rays irradiated to the ground surface and the long wavelength ultraviolet rays having a relatively long wavelength are harmful to the human body because they are absorbed into the ozone layer and reach the surface of the atmosphere.

In particular, long-wavelength ultraviolet light is involved in the formation of melanin in the human skin, causing pigmentation in the skin of the human body, and the medium-wave ultraviolet light having a higher energy is extremely harmful due to erythema, skin cancer, pigmentation, skin pouch degeneration and keratinization .
