Ultraviolet light sterilization becomes the first choice for sterilization in closed places, and ultraviolet light is generally classified into 3 types according to wavelength: long-wave Ultraviolet (UVA) of 315-380 nm, medium-wave Ultraviolet (UVB) of 280-315 nm and short-wave Ultraviolet (UVC) of 200-280 nm. Most of the currently available ultraviolet disinfection lamps utilize UVA and UVC ultraviolet rays to achieve disinfection. Ultraviolet ray disinfection is that ultraviolet ray is used for directly destroying the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in organism cells of microbial pathogens to cause growth cell death and/or regenerative cell death, so as to achieve the effect of sterilization and disinfection, and ultraviolet ray can kill various microorganisms including bacterial propagules, spores, mycobacteria, coronaviruses, fungi, rickettsiae, mycoplasma and the like, has broad spectrum, and can cause keratoconjunctivitis (external injury of eyes) and redness (reddening of skin) when being excessively contacted with ultraviolet radiation (254nm and 365 nm).
