Nobel laureate Shuji foresees UV LED as an anti-disease tool

By BizLED Bureau

Dec 4, 2014: According to Nobel laureate for physics Shuji Nakamura, who invented blue LED, ultraviolet LED could be a technology that can help eradicate deadly infectious diseases.
“UV LED allows us to have clean, pure water, which can be widely used to eliminate diseases such as Middle East Respiratory Syndrome (MERS) or Ebola,” Shuji said while addressing a press conference, organized by Seoul Semiconductor, to promote the importance of intellectual property in technology industries, including semiconductors and LEDs.

Ultraviolet is a light spectrum with a shorter wavelength than visible light. UVC light, one of the UV wavelength ranges, can be used to prevent bacteria or other forms of micro-organisms which reproduce and pollute water.

“UVC is the most promising area in the LED industry. We think it will resolve the issue of water and food shortages,” he said. He also emphasized upon the importance of LEDs to create a more energy-efficient world. LEDs lights are 20 times more energy efficient than incandescent lights, and four times more than fluorescent ones.

The Japanese government has decided not to allow fluorescent and incandescent lights to be used 2020 onward. Power saved from the LED technology could result in the closure of more than 50 redundant nuclear power plants across the globe by 2020, Shuji said. He is working with Seoul Semiconductor–nation’s leading LED maker that has been sponsoring his research project since 2003–to commercialize UV LED products..
