With this work we propose a guideline for the development of efficient and effective UVC surface disinfection systems for SARS-CoV-2 based on LED technology. The work analyzes the optical and electrical characteristics of state of the art UVC LEDs. From the most recent scientific literature, optical simulations, and laboratory experiments we propose guidelines for the design of high efficiency LED based antiviral system for the treatment of contaminated surfaces. To validate the guidelines two different UVC-LED irradiation systems, for spherical and flat surfaces, have been designed, manufactured and tested. Results indicate a log-4 inactivation of SARS-CoV-2 in few minutes.

Abstract

With this work we propose a guideline for the development of efficient and effective UVC surface disinfection systems for SARS-CoV-2 based on LED technology. The work analyzes the optical and electrical characteristics of state of the art UVC LEDs. From the most recent scientific literature, optical simulations, and laboratory experiments we propose guidelines for the design of high efficiency LED based antiviral system for the treatment of contaminated surfaces. To validate the guidelines two different UVC-LED irradiation systems, for spherical and flat surfaces, have been designed, manufactured and tested. Results indicate a log-4 inactivation of SARS-CoV-2 in few minutes.
