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 Kalinga Institute of Industrial Technology (KIIT), Deemed to be University, Bhubaneswar on January 6, 2018. Prof. Amano was delivering a talk on ‘Blue LEDs and Transformative Electronics for Developing Sustainable Smart Society’ under KIIT Knowledge Tree Lecture Series.
Lighting plays an important role in our everyday lives. 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% 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 after his talk.
Earlier, Dr. Mrutyunjay Suar, Director, KIIT School of Biotechnology introduced Prof. Hiroshi Amano to a packed auditorium. Prof. Amano is a Doctor of Engineering. Initially he studied electrical engineering at the university in Nagoya, which awarded him his doctorate in 1989. In 2002 he became a professor at Meijo University in Nagoya and later moved to Nagoya University. He was awarded the 2014 Nobel Prize in Physics together with Prof. Isamu Akasaki and Prof. Shuji Nakamura for “the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources”.
