Verification of inactivation effect of deep-ultraviolet LEDs on bacteria and viruses, and consideration of effective irradiation methods

With the widespread of novel coronavirus (SARS-CoV-2), inactivation bacteria and viruses using ultraviolet (UV) light has been reevaluated. However, there are many applications where safety to human body itself effect questioned, is a movement review UV-C guidelines (Global Lighting Association, Position Statement on Germicidal Irradiation SAFETY GUIDELINES, 2020). Since Minamata Convention Mercurybans production mercury in principle, deep-ultraviolet light-emitting diodes (UVC-LEDs) now being used place lamps. In this paper, we will discuss effective irradiation methods for pathogens solid surfaces, water, aerosols UVC-LED.
