Detailed introduction of UVC ultraviolet lamp
2022-08-04

The UV-C wavelength range is 100-280nm. C-band UV lamps are commonly known as UV germicidal lamps. UVC germicidal lamp is a low-pressure mercury lamp, which is excited by lower mercury vapor pressure (<10-2 Pa) to emit ultraviolet light. There are two main spectral lines: one is 253.7nm wavelength; the other is It is 185nm wavelength, both of which are C-band ultraviolet rays invisible to the naked eye.

Ultraviolet disinfection technology has unparalleled sterilization efficiency of other technologies, and the sterilization efficiency can reach 99%-99.9%. The traditional chemical disinfection methods such as chlorine and ozone generally take 20 minutes to 1 hour to achieve the sterilization effect.

UVC germicidal lamps do not need to be converted into visible light, and the wavelength of 253.7nm can play a good sterilization effect. This is because cells have a regular absorption spectrum of light waves. The ultraviolet rays at 250-270nm have the greatest absorption and are absorbed. The ultraviolet light actually acts on the genetic material of the cell, that is, DNA. It plays a kind of photochemical effect. The energy of the ultraviolet photon is absorbed by the base pairs in the DNA, causing the genetic material to mutate, so that the bacteria immediately die or cannot reproduce. purpose of sterilization.

Ultraviolet germicidal lamps are generally used to sterilize air, surfaces, and water. The wavelength of 253.7nm can effectively kill bacteria and viruses. The predecessors have already conducted a lot of research, which is a fact without a doubt. The characteristics of ultraviolet sterilization are broad-spectrum, and some viruses that are difficult to eliminate at high temperatures can be quickly eliminated with ultraviolet rays. This is because the sterilization mechanism of ultraviolet rays is different from other methods.

Sterilization: After the water molecules in the air and the photocatalyst-treated surface are catalyzed by ultraviolet rays, oxidation occurs to decompose the bacteria in the air.

Deodorization: Daily odor sources are mainly ammonia, hydrogen sulfide, methyl mercaptan, acetaldehyde, etc. Photocatalysts have more oxidizing ability than ozone and negative ions. These odor sources can be irradiated by fluorescent lamps in the presence of photocatalysts to produce photocatalyst oxidation. It acts to decompose the odor source.

 

How to clean the UV lamp?

Taking into account the safety of the home environment, we will choose to install ultraviolet rays, etc., which can play a role in disinfection, especially for families with the elderly and children at home, the installation of ultraviolet lamps is also to reduce the chance of the elderly and children getting sick. So how do you clean the UV light?

One of the main functions of the ultraviolet disinfection lamp is to be used for indoor sterilization and disinfection of the family. For example, if there are elderly people at home, pets or babies are kept at home, you can often use ultraviolet disinfection lamps, which can effectively destroy the DNA and RNA structure of bacteria, kill bacteria and inhibit the growth of bacteria and germs. At the same time, some enclosed spaces can also use ultraviolet disinfection lamps, including refrigerators, wardrobes, cars, etc., can use ultraviolet disinfection lamps.

Ultraviolet light is a low-energy electromagnetic wave, which is widely used in medical treatment, health and epidemic prevention, the food industry, pharmaceutical industry, and other departments because of its good bactericidal effect. However, how to use the ultraviolet lamp correctly to ensure its sterilization effect, prolong the service life of the lamp tube, and avoid accidental injury requires every operator to master it first. For places with poor light and ventilation in the home, ultraviolet germicidal lamps are often used, which can effectively kill various germs such as (bedding) mites and effectively create a healthy living environment.

When using ultraviolet disinfection lamps, the environment should be kept clean, and there should be no dust and water mist in the air. When the indoor temperature is lower than 20 degrees Celsius or the relative humidity exceeds 50%, the irradiation time should be extended. After scrubbing the floor, wait for the floor to dry before sterilizing it with a UV lamp.

Regular cleaning of the UV lamp is also to ensure the aesthetics and disinfection effect of the lighting. When cleaning, you must pay attention to selecting the appropriate cleaning agent, and dry the lighting in time after cleaning. The above is the relevant introduction to how to clean the ultraviolet lamp and what the ultraviolet lamp does. You can refer to it when cleaning the ultraviolet lamp to avoid damage to the lamp caused by the wrong cleaning method.
