The use of such products for indoor disinfection is currently one of the common disinfection methods in public places. The wavelength of the UV lamp is 200-270nm, the sterilization center wavelength is 253.7nm, which is a short-wave ultraviolet light, this ultraviolet radiation mainly through radiation damage and destroy the nucleic acid function of microorganisms (bacteria, viruses, spores) to kill microorganisms and other pathogens), to achieve the purpose of disinfection.
Commonly used UV disinfection lamp specifications are 15W, 20W, 30W and 40W, using voltage of 220V, mainly used for sterilization of personnel, generally installed in the disinfection of locker rooms and laboratories.
