Berlin researchers develop UVC LEDs to fight coronaviruses
In the joint CORSA project, SARS-CoV-2 and other respiratory viruses on surfaces and skin are to be deactivated by using UVC light. The project team is developing special UVC LEDs for this purpose and is investigating parameters such as wavelengths, irradiation doses and virus habitats. The German Federal Ministry of Education and Research is supporting the three-year project from 2021 with a total of three million euros.
Like bacteria and fungi, viruses can be inactivated by UVC light. However, for the current coronavirus, no reliable data on the optimal wavelengths and irradiation doses have been available to date. This is to change with the CORSA project (Deactivation of SARS-CoV-2 by UVC light and tolerability for humans), which has commenced.

Osram unveils its first UV-C LEDs
Osram Opto Semiconductors GmbH of Regensburg, Germany has launched its first UV-C LED, the Oslon UV 3636, representing the beginning of a comprehensive portfolio of LEDs in the UV-C LED sector.
Irradiation with UV-C light can eliminate 99.9% of viruses and bacteria on surfaces, in the air and in drinking water. It causes chemical bonds in the RNA or DNA helix of pathogens to break down, so they are no longer able to multiply and are thus rendered harmless. UV-C light has been used for many years to disinfect air or water – but often with very large lamps based on conventional light technologies.
