The principle of action of multifunctional germicidal light is to use UVC ultraviolet rays (wavelength 200 nm to 280 nm) with bactericidal effect to destroy the molecular structure of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) of microbial cells, causing growing cells and (or) Regenerative cells die, thereby achieving the effect of sterilization and disinfection.

Most of the multifunctional germicidal lights on the market currently use low-pressure mercury light sources with mature technology. There are two main glass materials for low pressure mercury lamps - quartz glass and high boron glass. The UVC ultraviolet rays in the multifunctional germicidal light have weak penetrating power and cannot penetrate ordinary glass.

The average person may not be able to distinguish whether the multifunctional germicidal light uses quartz glass, high boron glass or ordinary glass. Therefore, when buying multifunctional germicidal light, it is recommended not to buy multifunctional germicidal light from an unknown brand for cheap, or think that as long as the multifunctional germicidal light can be lit up, it can be sterilized and disinfected, but in fact it may not be effective.

Through the above introduction and analysis of multifunctional germicidal light, hope it helps you.
