Recently, it was learned that the UVC LED chip provided by BeyondUV Semiconductor (Hangzhou) Co., Ltd., a global leader in UVC LED chips and disinfection equipment, was applied to the latest green disinfection equipment of BeyondSmartor Technology (Beijing) Co., Ltd., and was tested by P3 Laboratory of Jiangsu CDC for SARS-CoV-2 inactivation experiment. As a result, SARS-CoV-2 of COVID-19 was easily inactivated, with inactivation rate of 99.994% in only few seconds. Professor Sun Wenjun of Tsinghua University, head of the Covid-19 Inactivation Working Group of the International Ultraviolet Association (IUVA), pointed out that this is the first time in the world that the official P3 laboratory has verified that ultraviolet UVC LED can inactivate Covid-19 in seconds, which is really encouraging and provides an important basis for using UVC LED technology to prevent and control Covid-19.
Since the outbreak of COVID-19, the world-renowned universities and related testing institutions have successively carried out experiments to verify the inactivation of SARS-CoV-2 of Covid-19 by UVC LED. For example, Crystal IS, a subsidiary of Asahi Kasei in Japan, cooperated with Boston University, Toyota Synthetic in Japan with Biomedical Science Association, a non-profit organization, and so on. However, in China, the results of inactivation test of Covid-19 in official laboratories have not been reported in newspapers.
According to Dr. Huang Xiaohui, COO of BeyondUV Semiconductor, "the wavelength of UVC LED is 260nm to 270nm, which is an ideal sterilization range. Recently, the power of UVC LED chips in our company has increased rapidly. A single 100mW chip can be mass-produced stably, with a light intensity of 3mW per square centimeter, and the Covid-19 can be inactivated in a few seconds, with an inactivation rate exceeding 99.994% ".
Chen Wenhua (David), COO of BeyondSmartor Technology (Beijing) Co., Ltd., said, "The tested equipment is applied to a single UVC LED chip developed and produced by BeyondUV Semiconductor (Hangzhou) Co., Ltd, which has obtained a meticulous optical structure patent, and a highly directional and efficient sterilization engine module is designed, which can be easily integrated on automatic disinfection equipment such as disinfection platform, disinfection robot, etc., without human intervention, or developed into portable hand-held disinfection equipment, which can flexibly and conveniently kill and realize human-machine coexistence". David also said, "Recently, cold chain logistics disinfection methods and equipment have been gradually upgraded. The company's UVC tunnel physical cold chain logistics disinfection system integrates this tested efficient sterilization engine, which can effectively kill bacteria and viruses in very low temperature environment, and the disinfection efficiency of six surfaces of objects reaches 500 pieces per minute. It is efficient and fast, and at the same time, it solves the problems of secondary pollution and residue caused by the disinfection of traditional chemical reagent spraying. He also said, "Effective innovation often comes from re-innovation of existing technologies, and we are constantly innovating and surpassing from the perspective of customer-centered and truly solving customer problems".
It is understood that the UVC LED sterilization engine of BeyondSmartor has a light power of 4W, and the UVC ultraviolet light emitted can not only kill drug-resistant bacteria and viruses such as Escherichia coli, Staphylococcus aureus, H1N1 influenza virus, spores, etc. in seconds, but this time, it was tested by P3 Laboratory of CDC, which verified that it can inactivate the coronavirus SARS-CoV-2 in seconds. During the global outbreak of COVID-19 pneumonia, it provided another sharp weapon for long-term social epidemic prevention.
In the medical industry, this technology has been used to disinfect the protective clothing of doctors and nurses when they enter or leave the isolation ward of coronavirus infection areas. Doctors and nurses are irradiated by all-round high-energy and high-quality ultraviolet rays for about 30 seconds. The selected wavelength changes the structure of viral RNA in a short time, inactivating it and no longer posing a threat to people. Because protective clothing can prevent ultraviolet radiation from penetrating, it is harmless to human body. In order to make the invisible ultraviolet radiation known when working, the protective device cover is coated with fluorescent paint, which will be lit up once the UVC LED is activated, that means it is very safe.
According to the test of inactivating SARS-CoV-2 of COVID-19 by CDC P3 Laboratory, it is confirmed that BeyondSmartor UVC LED series disinfection equipment which can inactivate SARS-CoV-2 of Covid-19 in seconds will be widely used in medical institutions, hotels, schools, airports, railway stations, airplanes and other public places with high frequency of people to prevent and control the spread of Covid-19 pneumonia and other respiratory diseases.
