The blue light-emitting diode (LED) lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world, who lack access to electricity grids, said Prof Hiroshi Amano, Nobel Laureate in Physics (2014), Japan at KIIT on Saturday.
Prof Amano was delivering a talk on 'Blue LEDs and Transformative Electronics for Developing Sustainable Smart Society' under KIIT Knowledge Tree Lecture Series.
The development of light-emitting diodes (LEDs) has made more efficient light sources possible. Blue LEDs proved to be much more difficult to create than red and green diodes. During the 1980s and 1990s Prof Isamu Akasaki, Prof Hiroshi Amano and Prof Shuji Nakamura successfully used the difficult-to-handle semiconductor gallium nitride (GaN) to create efficient blue LEDs.
"By using LED light, Japan reduced its annual electricity consumption by 7 per cent which translates to a saving of 1 trillion Yen. Consequently, energy efficient LED lights contribute to the reduction of CO2 emissions and global warming," the Nobel Laureate informed.
On the subject of 'Transformative Electronics for Developing Sustainable Smart Society', Prof Amano said work is going on in the field of ‘Internet of Energy’ and ‘Wireless Power Transmission Network.’ He spoke about the drone super highway, air-taxis. “In future we will be able to connect at any time and any place,” he said.
Many students and faculty members interacted with the Nobel Laureate in a question and answer session.
