Inventors of Blue LED Win Nobel Prize
Shuji Nakamura (pictured), Isamu Akasaki and Hiroshi Amano have won the 2014 Nobel Prize in Physics for their invention of the blue LED.
The Nobel committee said the innovation “has enabled bright and energy-saving white light sources.”
IHS Technology says the invention of blue LEDs was a game changer that led to the creation of white light—a cleaner, more energy-efficient and longer-lasting source of illumination that also has generated a multibillion-dollar market. Since the invention of blue LEDs in the early 1990s, the LED component market has flourished, reaching an estimated $17.7 billion in 2013, according to IHS.
The LED lighting market is poised for strong growth in the next five to 10 years with energy-hungry technologies being systematically banned across the world.
Nakamura is one of the founders of lighting company Soraa, which says its GaN on GaN blue LEDs produce more light per area of LED; handle more electric current per area than any other LED; and are more cost-effective than technology based on other substrates like sapphire or silicon carbide. The GaN on GaN crystals are up to a thousand times purer than any other LED crystal.
