Background technique

Nowadays, there are more and more dust particles and harmful bacteria in the air. Air quality index (AQI) in weather forecast has become an important indicator of people's attention. Smog contains a large number of viruses and bacteria, which often cause infectious diseases, especially resistance Weak elderly people and children are prone to infectious diseases in smog days, so the air pollution index is above mild pollution. People will wear masks when they go out, close windows indoors, and turn on air purifiers, but air purifiers have a small range of air purification and cannot Realize whole room purification; In 2018, swine fever caused by African swine fever virus (ASFV) broke out in many parts of the country. People were discouraged from pork, and it also caused huge economic losses to farmers.

Many experiments have proved that UV LED irradiation of viruses or bacteria, regardless of the type of bacteria and viruses, can directly destroy the DNA of bacteria and kill bacteria and viruses, and the killing rate has reached more than 99%. At present, people are developing various UV LED products to replace mercury Lamp sterilization and disinfection, because by 2020, ultraviolet LED will fully replace the mercury lamp sterilization and disinfection position, and be used in many fields such as medical treatment, water treatment, white goods, etc., to help people eliminate viruses and bacteria around them, and escort human health.
