In recent years, UV-C LEDs have become increasingly popular as a disinfection tool due to their ability to effectively destroy viral and bacterial DNA structures. However, one of the main drawbacks of UV-C LEDs has been their limited light output compared to mercury lamps, particularly in situations that require high disinfection performance.
Toyoda Gosei Co., Ltd. has recently developed high-power deep ultraviolet (UV-C) LEDs that are able to achieve light output levels of 200 milliwatts with a single chip. By enhancing the LED structure and composition, Toyoda Gosei has quadrupled the amount of light that can be extracted, resulting in improved disinfection capabilities that are about three times higher than before.
These advanced UV-C LEDs are compact, mercury-free, and have a longer lifespan than traditional mercury lamps. They are an eco-friendly alternative that is perfect for use in public spaces such as hospitals, airports, and schools. Sample sales of Toyoda Gosei’s high-power UV-C LEDs will begin internationally in April 2024 with plans to expand their use for disinfecting water, air and surfaces. The company aims to position these LEDs as a future alternative to mercury lamps and contribute to more hygienic and safer living environments.
