In 2003, the situation of "all people with one heart, fighting against SARS" is still vivid.

Today, 17 years later, the pneumonia epidemic caused by the new coronavirus that broke out in Wuhan has spread rapidly in just over a month. At present, the number of confirmed cases nationwide has exceeded 10,000, and the cumulative number of cases reported in Hubei Province alone has exceeded 10,000. And this number is still increasing, and the prevention and control situation is grim.

At the same time, cases of new pneumonia have also appeared in foreign countries, and many countries have declared a state of public health emergency. On January 30, the World Health Organization announced that it would list China's new crown virus epidemic as a "public health emergency of international concern."

At present, the fight against the new crown pneumonia has become a nationwide battle. Governments, organizations and units at all levels work together to fight the epidemic together to ensure the health and safety of the people.

A large proportion of the confirmed patients in this epidemic were infected while taking public transportation such as planes and trains. In order to curb the rapid spread of the virus and cut off the source of the virus, the three major airports in the United States have activated UVC ultraviolet sterilization robots to fully sterilize all aircraft cabins entering and leaving the port.

The United States pays attention to public health safety, and its airport application of UVC ultraviolet rays for sterilization and disinfection is also worthy of our reference.

Why can UVC LED be sterilized? Its working principle is to destroy the molecular structure of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) of microbial cells, causing the death of growing cells and (or) regenerative cells to achieve the effect of sterilization and disinfection. In particular, ultraviolet rays in the 240nm-280m band are the most effective disinfection bands. All coronaviruses are single-stranded positive-stranded RNA viruses.

In this new crown pneumonia epidemic, the demand for "ultraviolet sterilization lamps" is strong. Many lighting companies care about their home and country and generously donated ultraviolet disinfection lamps to support the prevention and control of new pneumonia. Compared with the traditional sterilization method, the ultraviolet germicidal lamp has a more thorough sterilization effect and can inactivate microorganisms, thereby helping to create a safer indoor working environment.

Since public spaces are relatively closed, such as hospitals, shopping malls, office buildings, airports, etc., where crowds are gathered and the air is not well circulated, the risk of virus infection is high. Disinfection and sterilization are particularly important in the prevention and control of epidemics. UVC LEDs can play an important role in disinfection and disinfection in public places by virtue of their safety, environmental protection, compactness, high efficiency, low consumption and other characteristics of no chemical residues, and will be more and more used in the future.

At the same time, with the development of the industry, the application form of UVC LED will become more and more abundant, and customized products will be more abundant, which can cope with various application scenarios, especially the application in public places, which is very conducive to reducing and isolating viruses. The spread and spread of bacteria.

In addition to UV germicidal lamps, UVC LEDs have also entered the general consumer market, such as air purifiers, home appliances, etc. The market is widely used, and many emerging markets have been created, including baby products, daily contact mobile phones, escalators, and household products Cleaning such as toothbrushes, cabinet lights, sports water bottles, thermos bottles, etc.

In fact, the development of UVC LEDs also meets the requirements of the International Environmental Protection "Minamata Convention". The International Minamata Convention, which prohibits mercury (mercury), came into force in August 2017. The treaty clearly ordered countries to gradually reduce the production and trade of mercury-containing products, including mercury-containing batteries, switches, energy-saving lamps, and cosmetics, starting in 2020. Thermometers and blood pressure meters that use mercury should also be replaced by 2020. More than 90 countries, including Japan, China, the European Union, etc., are in need of UV LEDs to replace these ultraviolet mercury lamps in the household and industrial UV lamps, which has also accelerated the take-off of the UV LED market around the world.

Moreover, with the continuous advancement of technology, the cost-effectiveness and luminous efficiency of UVC LEDs and the distance between mercury lamps will become smaller and smaller. Many domestic manufacturers are striving to achieve high cost-effective products and let UVC LEDs benefit the public.

According to the "2019 Deep Ultraviolet LED Application Market Report" released by LEDinside, the global UV LED market in 2018 reached 299 million U.S. dollars. It is expected that the market size will reach 991 million U.S. dollars by 2023, with a compound growth rate of 27% in 2018-2023. The broad development prospects of UV LED are attracting more and more manufacturers to enter.
