Osram granted approval to use UV light for virus elimination
The use in hospitals in Wuhan and Beijing, China, has also confirmed their effectiveness against coronavirus. The AirZing product series allows trained staff in hospitals and other public facilities to disinfect large areas. In China, Osram has supplied as many as 10,000 products to nurseries. The nucleus of microorganisms such as bacteria and viruses contains thymine, a chemical element of the DNA/RNA. This element absorbs UV‑C at a specific wavelength of 253.7 nm and changes to such an extent that the cell is no longer able to multiply and survive. V‑UV light (185 nm) also kills microorganisms but causes ozone that is harmful to human health. UV‑C light is ozone-free and therefore safer. UV‑C light is invisible and can lead to severe burns on human skin, which is why Osram has equipped its AirZing PRO with intelligent sensors. The infrared sensor detects people in the room and immediately turns off AirZing when someone unexpectedly enters the room to avoid injuries to eyes and skin.
