The Global laureate to influence the future lighting: the high-efficient blue LEDs of Shuji Nakamura
Today the Global Energy Prize laureate Shuji Nakamura shared his experience on the invention of high-efficient blue LEDS and their impact on the future lighting technology. He gave a keynote lecture on the subject within the “Electronic Materials Synthesis” theme for 2016 Nelson W. Tylor Lecture Series at Penn State`s University.
Recall that Shuji Nakamura was selected the 2015 Global Energy Prize laureate for the invention, commercialization and development of energy-efficient white LED lighting technology. His invention of blue LED was a necessary precondition for it: it has opened new approaches of obtaining pure white color and enabled further development of environmentally friendly light sources.
Taking into account, that lighting accounts for one-fourth of the world’s electricity consumption, LEDs are one of the most promising areas of electricity use. LED technology not only provides affordable sustainable source of light for millions around the world with little or no access to electricity grids, but also saves energy and reduces carbon emissions. According to DOE reports, transition to LED-based lighting will allow 300 TWh savings and reduce annual CO2 emissions by 210 million metric tons only in the USA.
“- Right now the biggest issue in the world is global warming. Every temperature rise increases the pressure. The best way to overcome global warming is to save energy. And the easiest way of doing that is by using LEDS for all kinds of lighting”, - declares Shuji Nakamura. –“The efficiency of a white LED is 2 times the one of a fluorescent lamp and 10 times then one of a traditional incandescent bulb. So by replacing these conventional lamps with white LEDs, we can save much more energy. Besides, LED light bulbs last for 50 years. At their current adoption rates, by 2020 LEDs can reduce the world’s need for electricity by the equivalent of nearly 60 nuclear power plants.”
Today Nakamura`s technology is ubiquitous. All companies involved with manufacture of semiconductors, mobile phones, digital camera recorders, TV and DVD appliances, airplane and car systems, street lighting systems, and traffic lights use it.
Speaking about his invention, Professor Nakamura also underlines: “At the end of the day, it is important for me to know that I have in some way contributed to improving the lives of others. It is rewarding to see just how far the invention of the blue LED has gone to aid people in reducing their electrical energy consumption thereby indirectly reducing our negative impact on the planet.”
For reference: The Nelson W. Taylor Lecture Series in Materials Science and Engineering honors the memory of Nelson W. Taylor (1869-1965) who is recognized as the individual most responsible for establishing the College of Earth and Mineral Sciences as a major center for ceramics research. The Nelson W. Taylor Lecture Series was established in 1969 and consistently attract scientists of international prominence.
