Some knowledge points of ultraviolet Germicidal lamp

UV Germicidal lamp is a non-contact, full space killing method with good effect and no residue. During the critical period of epidemic prevention and control, ultraviolet sterilization has been widely used in densely populated areas around the world. Huoshenshan Hospital in Wuhan has set up an ultraviolet Germicidal lamp for sterilization. Los Angeles Airport, San Francisco Airport, and John F. Kennedy Airport in New York have all activated ultraviolet sterilization robots to comprehensively sterilize all aircraft cabins entering and exiting the port. With the development of the COVID-19 and the enhancement of people's awareness of epidemic prevention, the market demand for UV Germicidal lamp, UV disinfection lamp and other related products has surged.
The ultraviolet light of the ultraviolet Germicidal lamp is an invisible light wave, which exists outside the ultraviolet end of the visible spectrum, so it is called ultraviolet light. It can destroy the molecular structure of DNA (DNA) and RNA (ribonucleic acid) of microbial cells, cause the death of growing cells and (or) regenerated cells, and achieve the effect of sterilization, especially with 200nm-280nm ultraviolet light.
The ultraviolet Germicidal lamp is a low-voltage mercury vapor discharge lamp made of emergency glass or other ultraviolet transparent glass, which produces ultraviolet radiation with a peak wavelength of 253.7 nm, and 2019 nCoV is nuclear free. Once it enters the human body, it will "hijack" our healthy cells to enable them to replicate the virus, while ultraviolet light can effectively destroy their molecular structure, prevent their replication, and achieve the effect of killing. In addition to 253.7 nm, the emission line of the ultraviolet Germicidal lamp also includes 185 nm, which can change O in the air into O (ozone). Ozone itself has a bactericidal effect. When the Germicidal lamp works, the heat brought by the conversion of electric energy into ultraviolet light is "three pronged approach" for COVID-19.
When purchasing the ultraviolet Germicidal lamp, pay attention to the relationship between the ultraviolet intensity and the space size. According to the requirements of WS/T367-2012 Technical Specification for Disinfection of Medical Institutions, the ultraviolet Germicidal lamp should be hung or moved for direct irradiation disinfection. The lifting height of the lamp tube from the ground is 1.8m~2.2m, and the average number of ultraviolet Germicidal lamp installed is more than 1.5W/m, that is, the power of the ultraviolet Germicidal lamp per cubic meter of space is required to be 1.5W.
It should be noted that all UV lamps have a certain lifespan and should be replaced promptly when in use. According to the requirements of GB/T 19258-2012, the service life of the ultraviolet lamp is not less than 5000h. However, due to the weak penetration of ultraviolet light in the air, the ultraviolet Radiant intensity intensity of the lamp tube will decline after long-term use, which is difficult to achieve the effect of remote sterilization. So when using, try to be as close as possible to the area that needs sterilization. For example, a distance of 1.5m-2m from the center of the room or a place where bacteria are prone to grow would be better.
The above are some knowledge points about the ultraviolet Germicidal lamp. I hope you can carefully study and understand the relevant knowledge and choose the equipment that suits your needs.
