The working principle of UV lights and precautions to be taken when working with UV lights:

How UV lamps kill microorganisms such as bacteria and viruses: 

The principle that UV lamps can kill microorganisms such as bacteria and viruses is to use ultraviolet radiation. The ultraviolet radiation emitted by UV lamps can damage the DNA and RNA of microorganisms, causing them to lose their reproductive ability, thereby achieving a bactericidal effect.

Specifically, ultraviolet rays can penetrate the cell wall and membrane of microorganisms, enter the cell interior, destroy the chemical bond of DNA and RNA molecules of microorganisms, and make them lose the ability of replication and reproduction. In addition, ultraviolet radiation can also damage the proteins and enzymes of microorganisms, causing them to lose their vitality and achieve bactericidal effects.

It should be noted that different types of microorganisms have different sensitivities to ultraviolet radiation. Some microorganisms have strong resistance to ultraviolet radiation and require longer periods of ultraviolet radiation to achieve bactericidal effects. Therefore, when using UV lamps for sterilization, it is necessary to choose the appropriate UV radiation time and intensity based on different types and quantities of microorganisms to achieve the best sterilization effect.

When working with UV lamps, the following precautions should be taken:

Avoid direct observation of UV lamps as UV rays are harmful to the eyes.

Avoid prolonged exposure to UV lamps as UV rays are harmful to the skin.

The usage time of UV lamps should be controlled within a certain range, as prolonged use can shorten the lifespan of the lamp tube.

The usage environment of UV lamps should be kept dry to avoid moisture on the lamp tubes.

The use of UV lamps should follow the instructions and do not disassemble or replace the lamp tubes at will.

The use of UV lamps should avoid contact with flammable substances and avoid accidents such as fires.
