Toyoda Gosei's High power UV-C LED
Toyoda Gosei Develops UV-C LED with World-Class Light Output
We succcessfully developed 275nm UV-C LEDs that achieve light output at the level of 200 mW with a single chip driven by a current of 350mA.
Improvement of the LED structure and composition quadrupled the amount of light that can be extracted.
Enhanced LED performance including disinfecting capability of about three times
higher will expand their applicable areas including a future alternative to mercury lamps,
contributing to more hygienic and safer living. * As of March 31, 2024. Toyoda Gosei survey
［Comparison to our previous LEDs］
* Reduction Equivalent UV Dose is an indicator of disinfection performance
