Prof. Shuji Nakamura - The Future is Laser Lighting

PROF. NAKAMURA SAID: "For violet LEDs we reach about 50-100 Acm-2 but the laser diode uses 3-10 kAcm-2 which is about 1,000 times higher than blue LEDs. This leads to very tiny chips in combination with the same phosphors such as YAG types. The light output is about 1,000 times higher than conventional LEDs with the same chip-size".

Prof. Shuji Nakamura
Shuji Nakamura was born on May 22, 1954, in Ehime, Japan. He received
his B.E., M.S., and Ph.D. degrees in electrical engineering from the University of Tokushima, Tokushima, Japan, in 1977, 1979, and 1994, respectively. He joined Nichia Chemical Industries Ltd., Tokushima, Japan, in 1979. In 1988, he spent a year at the University of Florida, Gainesville, FL, USA, as a Visiting Research Associate. In 1989, he started the research of blue LEDs using group-III nitride materials. In 1993 and 1995, he developed the first group-III nitride-based blue/green LEDs. He also developed the first group-III nitride-based violet laser diodes (LDs) in 1995. Since 2000, he has been a Professor at the Materials Department, University of California Santa Barbara, Santa Barbara, CA, USA. He holds more than 300 patents and has published more than 400 papers.

Dr. Nakamura has received a number of awards, including: The Nishina Memorial Award (1996), the MRS Medal Award (1997), the IEEE Jack A. Morton Award, the British Rank Prize (1998), and the Benjamin Franklin Medal Award (2002). He was elected a member of the U.S. National Academy of Engineering (NAE) in 2003. He received the Finnish Millennium Technology Prize in 2006. In 2008, he also received the prize of Asturias Award from Spain. He received the Harvey Prize of the Israel Institute of Technology in 2010. The 2014 Nobel Prize for physics has been awarded to a trio of scientists (Professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura) in Japan and the US for the invention of blue light emitting diodes. In June 2015 Professor Nakamura received the Global Energy Prize in St. Petersburg for the invention, commercialization and development of energy-efficient white lighting technology together with Jayant Baglia for the invention, development and commercialization of Insulated Gate Bipolar Transistor, which is one of the most important innovations for the control and distribution of energy.
