摘要
Due to a serious pandemic scenario. the surface disinfection process using monochromatic light sources based on UV-C LEDs is becoming more and more required. A brief review of the optoelectronics parameters of the devices based on UV-C LEDs light sources and the UV-C dose required to achieve a 99.9% of inactivation on surfaces (3 log reduction) of human Coronavims (HCov-OC=13 used as SARS-CoV-2 surrogate) has been prepared. A new parameter labeled as "homogeneity factor - has been defined to be applied on a bounded arca where the homogeneity of the distribution requires a reliable average dose.
