The IET Kelvin Lecture 2010 - Lighting up the future - the way ahead for solid-state lighting

Shuji Nakamura

We are now on the path towards a new illumination paradigm that can radically change the way we look at light forever!! This technology promises to enhance the quality, flexibility, and cost effectiveness of light delivery. Prof. Nakamura pioneered the first group-III nitride-based blue/green LEDs and group-III nitride-based violet laser diodes (LDs), bringing about a revolution in lighting technology.
LEDs are generally very long lasting and the typical red or yellow LEDs have estimated life-times of about more than 10 years, greatly reducing energy consumption and ongoing maintenance costs. No other single lighting technology presents so much potential to conserve valuable electricity. LEDs can provide high quality lighting in an increasing number of applications and now Nakamura is moving this remarkable phenomenon in technology forward into economic reality with a long term goal to Light-Up-The-World on implementation.

About the speaker

Shuji Nakamura was born on May 22, 1954 in Ehime, Japan. He obtained B.E., M.S., and Ph.D. degrees in Electrical Engineering from the University of Tokushima, Japan in 1977, 1979, and 1994, respectively. He joined Nichia Chemical Industries Ltd in 1979.
In 1988, he spent a year at the University of Florida 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.
He has received a number of awards, including: the Nishina Memorial Award (1996), MRS Medal Award (1997), IEEE Jack A. Morton Award, the British Rank Prize (1998) and Benjamin Franklin Medal Award (2002).
He was elected as the member of the US National Academy of Engineering (NAE) in 2003. Also, he received the Millennium Technology Prize in 2006. Since 2000, he is a professor of Materials Department of University of California Santa Barbara. He holds more than 100 patents and has published more than 390 papers in this field.
