LED industry pioneer was awarded the highest U.S. Engineering Award

[LED] Chinese news according to foreign media reports, the U.S. National Academy of Engineering (NAE) decided to 2015 Charles Stark Draper Award for five LED industry pioneer, they are Akasaki Yong (Isamu Akasaki), George Crawford (M. George Craford), Nick Nyak (Nick Holonyak Jr), Russo Dupuis (Russell Dupuis) and Nakamura Shuji (Shuji Nakamura). The award will be awarded to the five pioneers in Washington in February 24th.

Charles Stark Draper (Charles Stark Draper Prize), is one of the highest awards in the u.s.. The award is awarded every two years by the National Academy of engineering and is considered to be one of the Nobel prizes in the engineering field.

Draper, President and chief executive officer of the Kaigham J. Gabriel, said: "great engineers imagine and create new things. These five pioneers have created new technologies that have brought new light to our lives, and have spawned a great industry that has provided tens of thousands of jobs and made great contributions to energy conservation. "

LED father Nick Holonyak invented the first red light in 1962 LED. At that time, he was working in the Ge Corp, mainly engaged in III-V materials including gallium arsenide (GaAs) research. Later, he also developed the LED (GaAsP), is today all high brightness LED support.

George Craford invented the first yellow light LED in 1972, and led the team developed a nitrogen doped gallium arsenide, thereby enhancing its brightness. He also participated in the first large-scale commercial production of red LED. Subsequently, he developed the first high brightness yellow and red LED, and in decades to contribute to the development of efficient white LED.

Russell Dupuis in 1977 and developed a metal organic chemical vapor deposition (MOCVD) process, the high brightness LED production, and now high brightness LED, laser diodes, solar cells, high-speed photoelectric equipment production laid the foundation.

In 1987, Akasaki Yong made use of MOCVD machine to grow high quality gallium nitride crystal on sapphire substrate, which created the first blue light LED, which made it possible for bright and energy-saving white light source.

In the first 20 years of the existence of red and green LED, Blu ray LED was developed by the industry at that time considered an impossible thing. In 1992, Nakamura Shuji successfully developed a high brightness blue GaN based on LED. The invention of blue LED makes LED industry began the commercial production of white LED.

Long term, low heat, high efficiency and energy saving LED has been gradually recognized by people, and the application scope is more and more widely. The rapid growth of the LED industry has effectively stimulated global employment growth and significantly reduced energy costs. According to the U.S. Department of energy data show that in 2013, LED lighting for the United States to reduce carbon dioxide emissions by more than 12 million tons.
