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.

Uvc-led industry chain and application scenarios
The epidemic has spawned a large disinfection market. Ultraviolet disinfection lamps are widely used in the fields of ambient air disinfection, drinking water and sewage disinfection, clothing and tableware surface disinfection and so on. The outbreak of the epidemic has driven the market demand for ultraviolet sterilization. This epidemic has popularized and paid attention to consumers' awareness of ultraviolet sterilization, which provides a good development opportunity for UVC.
UVC led UV lamps that have emerged in recent years show the trend of replacing mercury lamps in many application scenarios, such as sterilization and bacteriostasis of domestic and commercial water purifiers, sterilization and bacteriostasis of refrigerator freezers, sterilization and bacteriostasis of washing machines, sterilization of air conditioners, sterilization of intelligent toilets and so on. More and more applications are equipped with UVC led sterilization schemes.
Compared with mercury lamp and ultraviolet lamp, UVC LED has higher energy density, which is convenient for use in small-size confined space. It can achieve man-machine coexistence, overcome the disadvantage that people and animals must be cleared in the working process of traditional mercury lamp and ultraviolet lamp, and make the application of uvc-led have huge imagination space.
At present, the UVC LED industry is still at a relatively low technical level, with photoelectric conversion efficiency of only 1.5-2%, and the high cost of packaging materials. However, combined with its advantages of small size, low power consumption, environmental friendliness, high efficiency, energy conservation, safety, reliability and environmental protection, it is also after the signing of Minamata convention banning mercury containing products by the United Nations, The only UV light source product that can replace mercury lamp.
Qingdao fluorescent Innovation Technology Co., Ltd. has a professional postdoctoral team, focusing on the research of ultraviolet sterilization application. After years of deep cultivation in the ultraviolet industry, the company has obtained a number of national invention and utility model patents. At present, a number of sterilization module products have been put into the market.
