The principle of ultraviolet sterilization and disinfection of UV Sterilizer lamp is to use ultraviolet rays of appropriate wavelengths to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial cells, causing growth cell death and (or) regenerative cells death, to achieve the effect of sterilization and disinfection.

The UV Sterilizer lamp does not need to be converted into visible light, and the wavelength of 253.7nm can play a good sterilization effect. This is because the absorption spectrum of light waves by cells has a rule. The ultraviolet rays at 250~270nm have the greatest absorption and are absorbed. The ultraviolet rays actually act on the genetic material of the cell, the DNA, which acts as a kind of photochemical effect.

The energy of the ultraviolet photons of the UV Sterilizer lamp is absorbed by the base pairs in the DNA, causing the genetic material to mutate, so that the bacteria immediately die or cannot reproduce, and the purpose of sterilization is achieved.
