Self organising ultraviolet LEDs used for Covid-19 sterilisation can enable low cost gigabit LiFi light networks say researchers at Tohoku University in Japan
"Deep ultraviolet LEDs are currently mass produced in factories for applications related to Covid-19," Kojima said. These are used for sterilization processes. "So, they're cheap and practical to use," he said. "The mechanism underlying this speed is in how a lot of tiny LEDs self-organize in a single deep ultraviolet LED," said Kojima.
"The tiny LED ensemble helps with both power and speed."
