Peak Value: ams OSRAM Doubles UV-C LED Efficiency
Peak Value: ams OSRAM Doubles UV-C LED Efficiency Battling germs with UV-C radiation: disinfection with light is gaining global importance — in hospitals, offices, kitchens, and bathrooms. Even tap water can be disinfected using UV-C radiation. ams OSRAM has now achieved a technological breakthrough in this field within the scope of the evaluation of a new UV-C LED. The LED delivers over 10 percent efficiency at 200 milliwatts power, a wavelength of 265 nanometers, and a lifespan exceeding 20,000 hours. With these specifications, it can replace conventional mercury discharge lamps in the future. The LED’s efficiency has been validated by Germany’s National Metrology Institute Physikalisch-Technische Bundesanstalt (PTB). Read more »
