The new coronavirus is sensitive to ultraviolet rays, opportunities for the LED industry under the epidemic


The "New Coronavirus Infection Pneumonia Diagnosis and Treatment Plan (Trial Version 5)" pointed out that the new coronavirus is sensitive to ultraviolet light. Recent studies have found that there is a correlation between the new coronavirus and the SARS coronavirus. Therefore, in theory, the scientific and rational use of ultraviolet light can effectively inactivate the coronavirus.
 
Ultraviolet sterilization technology is one of the most commonly used and oldest sterilization technologies in medicine, and has a history of more than 100 years. It is understood that according to the wavelength, the ultraviolet band is divided into UVA, UVB and UVC from long to short. Among them, deep ultraviolet UVC is the band with the shortest wavelength and the highest energy. In the ultraviolet band, the band with direct sterilization capability is UVC.
 
During the SARS period in 2003, 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 90 μW/cm2 for 30 minutes to irradiate the coronavirus can kill the SARS virus.
 
Although there is no test report of a third-party testing laboratory using deep ultraviolet to kill the new coronavirus in this epidemic, many professionals in the industry say that UVC targets the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) of bacteria and viruses. ) Has an efficient killing effect, and the new coronavirus is an RNA virus. In practice, the UVC inactivation dose of the new coronavirus requires further experiments by relevant government departments and scientific research institutions to clarify. At present, the inactivation dose of SARS virus is generally referred to.
