Abstract:UVC LEDs are of fundamental importance for many applications, including sterilization and disinfection, thanks to their high efficiency and low environmental impact. However, several physical processes still limit the lifetime and reliability of these devices.We present recent case studies in the field of UVC LED reliability. Initially, we review the performance/efficiency of state-of-the-art commercial devices, and discuss the issues related to LED self-heating, and the related electro-optical transient behav… Show more
