Toyoda Gosei develops DUV LED light module for sterilization

Taking advantage of technology accumulated over 30 years in the development and production of blue light-emitting diodes, Toyoda Gosei Co Ltd of Kiyosu, Aichi Prefecture, Japan has developed a deep-ultraviolet (DUV) LED light module for use in the sterilization of water, air and surfaces.

Deep UV LEDs emit short-wavelength ultraviolet light that can destroy the genetic materials of viruses and bacteria. They are promising as a new sterilizing light source that can be used in place of mercury lamps, for which there is environmental concern.

With the aim of spreading applications of this technology, Toyoda Gosei has been developing products in modules or units with waterproof or heat-dissipation features. In a joint experiment conducted with Japan’s Biomedical Science Association (a certified non-profit organization consisting of specialists from national research institutes and universities in medicine, pharmaceutics, veterinary medicine, agriculture etc) using human coronavirus 229E (HCoV-229E), which has genetic materials similar to those of the virus that causes Covid-19 (SARS-CoV2), these modules were demonstrated to be highly effective in sterilization.

Toyoda Gosei is cooperating with the Toyota Group and other companies to develop applications for water, air and surface sterilization that contribute to safer and healthier living.
