There are three commonly used disinfection methods, namely physical disinfection, chemical disinfection and biological disinfection.

Under the influence of the epidemic, many people's lives have been affected, and people's awareness of health has also increased and attached importance to it. In line with the lifestyle after the epidemic, many manufacturers have successively developed a sterilization module for air and space - UVC led UV sterilization products. The finished products can achieve rapid and efficient bacteriostasis after matching with the sterilization module.

At the end of 2019, novel coronavirus swept the world, and everyone had to passively receive a health education, raising an unprecedented demand for the "sterilization" function of daily necessities in close contact with themselves. The elements of life that we often contact in life are naturally the first to be paid attention to.

According to different biological effects, ultraviolet light is divided into four bands according to wavelength: long wave UVA, medium wave UVB and short wave UVC. The longer the wavelength, the stronger the penetration.

Principle of ultraviolet sterilization: through ultraviolet irradiation on bacteria, viruses and other microorganisms, destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial body cells, cause DNA strand breakage, cross-linking rupture of nucleic acid and protein, and cause growth cell death and regenerative cell death, so as to achieve the effect of sterilization and disinfection. Among them, the ultraviolet disinfection with the wavelength of 253.7 nm is the best.

The most popular product in the LED industry this year is the UV disinfection products of UVC series. The last article explained in detail what UVC is and the principle of UV disinfection and sterilization. In this issue, we will take you to understand the materials we use for the mass production of UVC light source.
