Ultraviolet refers to a generic term for radiation in the electromagnetic spectrum having wavelengths from 100nm to 400nm, which does not cause human vision. The ultraviolet rays are classified into UVA (wavelength of 320 to 400nm), UVB (wavelength of 275 to 320nm), UVC (wavelength of 200 to 275nm) and UVD (wavelength of 100 to 200 nm).

UVC, which has a short wavelength, is absorbed and scattered by the ozone layer in the atmosphere and thus cannot reach the ground. But it has good effect of killing bacteria and fungi because it is a kind of sterilizing ultraviolet ray. Has been widely used for air sterilization in operating rooms and sterile wards in hospitals. But at the same time, UVC has great harm to human body, can burn skin after being irradiated to human body for a short time, and can cause skin cancer after being irradiated for a long time at high intensity. Therefore, there is a contradiction that medical staff cannot work simultaneously when UVC air disinfects.

UVC has a weak penetration ability and cannot penetrate transparent glass and organic glass. The air is continuously filtered into the cavity with the baffle for air disinfection, so that the powerful sterilization effect of the UVC is kept, and the problem of harm of the UVC to workers is solved. Dynamic air disinfection keeps the workplace continuously sterile.

Common UVC lamps radiate UVC ultraviolet light over a wide range of wavelengths, even with visible light, such as violet light.
