A Beam of Sanitizing Light Disinfection with filtered far-UV-C

摘要

THE COVID-19 PANDEMIC is driving interest in broader applications of germicidal ultraviolet (GUV) lamps to disinfect building spaces. The challenge with GUV is that it is harmful to human health as well as viruses and bacteria, which limits its application in occupied spaces. However, a portion of the UV spectrum-within recommended limits-is effective against pathogens while posing a minimal risk to humans, which offers potential for disinfection in occupied spaces. This technology, pioneered by Columbia University, New York, and commercialized by Ushio Inc., Tokyo, is poised to enter the North American lighting market through Atlanta-based Acuity Brands.
