One year has passed since the outbreak of the COVID-2019. In 2020, people around the world are living in a terrifying epidemic atmosphere. According to statistics released by Johns Hopkins University in the United States, as of 23:22 on January 18, Beijing time, The number of confirmed cases of new coronary pneumonia worldwide rose to 95,155,602, of which 2,033,072 deaths. After this epidemic, the whole society has increased its health awareness, and the status of the disinfection and purification industry in protecting people's lives and health has undoubtedly improved. Among them, ultraviolet LED sterilization, as a means of disinfection protection, has also accelerated the pace of growth due to the catalysis of the epidemic.
Ultraviolet disinfection is a traditional and effective method. During the SARS period, experts from the Institute of Viral Disease Control and Prevention of the Chinese Center for Disease Control and Prevention found that the use of ultraviolet rays with an intensity greater than 90μW/cm2 for 30 minutes to irradiate the coronavirus can kill the SARS virus. The "New Coronavirus Infection Pneumonia Diagnosis and Treatment Plan (Trial Version 5)" pointed out that the new coronavirus is sensitive to ultraviolet light. Recently, Nichia Chemical Industry Co., Ltd. announced that in an experiment using 280nm deep ultraviolet LEDs, it was confirmed that the new coronavirus (SARS-CoV-2) fire extinguishing effect after 30 seconds of deep ultraviolet irradiation was 99.99%. Therefore, in theory, the scientific and rational use of ultraviolet light can effectively inactivate coronavirus.
From the current application point of view, deep ultraviolet LEDs are widely used in civilian fields such as water purification, air purification, surface disinfection, and biological detection. In addition, the application of ultraviolet light sources is far more than sterilization and disinfection. It also has broad prospects in many emerging fields such as biochemical detection, sterilization and medical treatment, polymer curing and industrial photocatalysis.
Based on the huge application potential of deep ultraviolet, deep ultraviolet LED is completely possible to develop into a new trillion-level industry different from LED lighting in 2021. As LED has the advantages of small and portable, environmentally friendly and safe, easy to design and no delay lighting, the application of deep ultraviolet LED is easier to be extended to portable disinfection electronic products, such as maternal and child sterilizer, elevator handrail sterilizer, mini washing machine built-in UV Germicidal lamps, sweeping robots, etc. Compared with mercury lamp ultraviolet lamps, UVC-LED has higher energy density, which is convenient for use in small confined spaces. It can coexist with man and machine. It overcomes the shortcomings of people and animals that must be emptied during the work of traditional mercury lamp ultraviolet lamps. UVC -LED applications have a huge application space in near future.
