Development of far-UVC LEDs and their application in irradiation systems for antisepsis and sensing

Abstract

Far-UVC LEDs are interesting for applications such as skin-tolerant inactivation of multiresistant pathogens and gas sensing. We present the development of 233 nm AlGaN-based far-UVC LEDs with an emission power of 3 mW at 200 mA and L50 lifetime of more than 1000 h, after burn-in. Additionally, the design of a far-UVC LED-based irradiation system, with a spectral filter which supresses emission >240 nm, to study the inactivation of bacteria and skin compatibility of the radiation will be presented. The system can be used to homogeneously irradiate a target area of 70 mm diameter with a mean irradiance of 0.4 mW/cm².
