Following international approval, Osram can now supply UV-C systems for disinfecting air and surfaces. Osram’s UV-C HNS lamps work at a wavelength of 253.7 nm and obliterate viruses and bacteria with a reliability of 99.9 percent.
In order to protect people from harmful UV-C light, Osram’s products can be equipped with intelligent sensors. The AirZingTM product series allows trained staff in public facilities to disinfect large areas.
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.
