Just as we wrote about how LED light is paving the way, the trio of Japanese scientists who were considered pivotal in this invention were awarded the Nobel Peace Prize in Physics. Honored for inventing the efficient blue light-emitting diodes which have enabled energy-saving white light sources that can last up to 100,000 hours, the prize was awarded to Isamu Akasaki of Meijo University and Nagoya University, Hioshi Amano of Nagoya University, and Shuji Nakamara a professor at the University of California, Santa Barbara.
This important step forward in light technology means that a past once dominated by incandescent bulbs will now open doors for future of LED lighting. LED lights, found in mobile phones, computer screens, televisions and cameras, are a much longer-lasting light and saving much more energy than before without the use of mercury.
“Initially, people said this research wouldn’t be completed within the 20th century, so colleagues left, one after another,” Mr. Akasaki said, speaking at Meijo University where he remains a professor at age 85. “It never occurred to me to abandon it. I just continued doing what I wanted to do. It didn’t matter to me whether I would succeed or fail.” (Source: The Wall Street Journal)
