Nakamura two scientists who have the courage to recover their reward

Known as "The father of Blu-ray" in the village of 1954 was born in the Japanese town of Yi-cho. 1994 from the Island of Japan

cid=30657&values=75428230&redirect=http://www.icourse163.org/"title=" "style=" Color:rgb (0,166,124); Text-decoration:none "> University received a PhD. He has been a U.S. citizen since 2000 at the University of California, Santa Barbara, USA.

1993, in Japan and Asia Chemical Industry Company (hereinafter referred to as "Japan and Asia Company") as a technician in the village developed a blue high-brightness light-emitting diode, led to the usefulness of an important step.

Such a good scientist. He left Japan for the United States in 2000. It's really confusing.

August 2001. Nakamura to the Tokyo District Court to sue the original owner of Japan company. The secret was opened by the claim to return all rights to the patent and to pay a royalties of 20 billion yen.

1993. Nakamura invented the Blu-ray diode, by the Japanese and Asian companies to apply for a patent.

In December, Japan and Asia began to produce blue-light diode lighting products, and achieved huge profits. However, Japan and Asia company paid only 20,000 yen for the "reward" (Patent and patent registration 10,000 yen each).

2000. Nakamura decided to travel to the United States. When the resignation procedure is processed. The company asked him to sign a contract to ensure that 3 years no longer engaged in the basic technology of blue light diode research, Nakamura refused. And therefore failed to receive the severance payment.

Nakamura to the United States after the university took office, Japan and Asia company unexpectedly after the United States let him sign contract, Nakamura again flatly refused. It was not expected that the company should be suspected of leaking corporate secrets in December 2000. He sued Nakamura and his adviser, the American firm, and the University of North Carolina in court.

So. The unbearable Nakamura in the Japanese company to sue Japan's court. January 11, 2005, under the auspices of the Tokyo High Court, Nakamura and Japan Asia Company reached a settlement, by the Japanese and Asian companies to pay a total of 843.91 million yen for the invention compensation.

The most beautiful flowers bloom in the red

He was born in Japan in 1929. He received his doctorate from Nagoya University in 1964. He has worked in the Matsushita Electric Industry company and is currently a professor at the famous University of Japan and a distinguished professor at Nagoya University.

In the early 70, the world launched a research craze for gallium nitride. The use of it to develop a Blu-ray diode is thought to be a bold assumption.

In the late 70, most scientists gave up.

However, the study of the red-dragon has finally laid the foundation for the use of gallium nitride materials in the manufacture of Blu-ray diodes. 2009. The Kyoto prize, known as the "Japanese Nobel Prize", was awarded to Osaki Yong.

In Japan, we are known for not being discouraged and persistent. He used to say, "even if it fails." And never give up.

In the case of failure. It's important not to be discouraged and give up. ”

Amano stood on the shoulders of his mentor, Hiro.

Amano-Ho is a Japanese project-learning family. Specializing in semiconductor device manufacturing, is currently a City University, Nagoya University professor.

Amano 1960 was born in Hamamatsu, Japan, 1989, Nagoya University, Ph. D., 1992 to the City University as an assistant professor, 1998 to 2002 to associate Professor, 2002 become a professor.

In 2010, Amano was professor at the Graduate School of Engineering, Nagoya University.

1982. Amano-Hao as an undergraduate to increase the professor of the research team, the study of the use of materials in the blue light-emitting diodes began.

Amano-Ho and his mentor, Auburn Yong, cooperated with the basic Blu-ray led research and development in Nagoya University, and successfully developed the Blu-ray led for the first time in 1989.

3 Japanese-born scientists won the 2014 Nobel Prize in Physics for discovering new energy-efficient light sources. The Nobel Prize in Physics awards 7th in the Swedish capital of Stockholm announced the news when it was decided. 3 winners invented a blue light emitting diode (LED). Help people get a white light source in a more energy-efficient way. The LED lights, which are based on this principle, "will illuminate the entire 21st century."

Blu-ray led only 20 years

3 winners were 85-year-old professor of the University of Ming Cheng, 54-year-old Nagoya University professor Amano-ho and 60-year-old University of California, Santa Barbara, Professor Nakamura-Xiu two. Zhong Cun Xiu ER is American nationality. Yang, a Chinese-American professor at the University of California, Berkeley, and Shoucheng Zhang, a Chinese professor at Stanford University, missed the Nobel Prize.

The Nobel Physics prize committee statement said the 3 scientists, in the early 90 's, had a fundamental shift in the lighting sector by exporting blue beams through semiconductors.

According to the introduction, LED light source and traditional light source compared with energy-saving, durable and other advantages. Red LEDs and green LEDs have long been invented. However, the long-term creation of Blu-ray led has become a problem, the lack of the three primary colors in the blue, can not be used for lighting, and let consumers feel comfortable white LED light source.

In 1973, at the time of the Matsushita Electric Company's Tokyo Institute, the first Blu-ray led research was started.

Later, the foundation of Blu-ray led research and development was conducted by the Nagoya University and Amano-ho. 1989 the first successful development of Blu-ray led. And Nakamura two was at that time in Japan and Asia Chemical Industry company. His useful research has led to the company's first-ever production of LEDs in 1993, triggering a technological revolution in lighting.

According to the judging committee, the only "20-year-old" "Young" invention was awarded because the white light source, which was created in a new way, had "benefited all of us".

1.5 billion people from around the world benefit

"Their inventions are revolutionary. "The selection committee said in a statement. "The incandescent lamp lit up in the 20th century. 21st century will be lit by LED lights. ”

Based on research data. Most advanced LED lamps can consume less than 20 of the average bulb, but their durability is 10 times and 100 times times more than fluorescent and incandescent lamps. and the lighting effect is more stable.

One of the roughly four points of global power generation is used for lighting purposes. The advent of LED lights has contributed to saving global resources. Right now. Many countries are pushing for a change in the LED lighting sector. To save a lot of other lighting power and even resources needed.

The selection committee also felt that the demand for electricity from LED lamps was low. Rely on local low-cost solar energy to use.

The advent of such a new light source has brought a higher quality of life to the world's 1.5 billion people who have failed to benefit from the grid.

Philippe Chevet, a physicist at the University of Maryland Joint Quantum Research Institute. The award of LED lighting studies shows that physics research can bring tangible benefits, not just the mysteries of the universe.

The three winners will split the Nobel Prize Prize for physics from SEK 8 million ($ 1.11 million).

Received the award speech

See LED lighting dream come true very comfortable

The 85-year-old, at a press conference held after the award, thanked his research team, saying, "I can't finish this alone."

As for the secret of success, he emphasized the dedication of the research team. He confessed. A number of people told him earlier that his research would not have been fruitful until the end of 20th century. "But I never felt that way ... I just keep doing what I want to do. "

In fact, the scientific community has worked for decades to invent blue LEDs, but it has not made a breakthrough. The Nobel Prize committee says the 3 scientists "have succeeded where others have failed".

In the United States, Nakamura repair two local time received the award-winning phone in the morning, the surprise even "unbelievable."

He then made a statement. "It's a pleasure to see our LED lighting dream come true," said the winner. It is hoped that energy-saving LED lamps will help reduce energy consumption. Reduce the cost of lighting worldwide ".

Peking University scholar

Bringing the energy revolution to a worthy award

Professor Qihuang, director of modern Optics at Peking University School of Physics, said yesterday that the award-winning three scientists had made a revolutionary contribution to the doubtful industry and that their inventions had been tested for 10 years. At the moment, LED lights have been widely used in life. Its low energy consumption has led to the energy revolution and has become the greatest contribution to society. So. The academic community is well-recognized for their awards.

Qihuang Introduction, is the mentor of Osaki Yong. Amano-Ho is his student. They were the first scientists to invent gallium nitride LEDs. At that time LED lights are mainly red or yellow, the invention of Blu-ray led almost impossible, but the village repair two finally make the invention into reality, will be red and yellow blue combination. Form the white light source used today. The inventions of the three scientists were very difficult in academic terms.

Qihuang said that LED lights have now been applied to all aspects of life. For example, the aircraft on the toilet lighting using LED lights, the computer display on the small dot is LED lights, children almost all of the toys are used lde lights.

"Physics is always about making a contribution to human beings, not always on the armchair. This 10-year led development is very fast. Also verified their results.

"Qihuang said. Each year, there are dozens of scientists who have won the award, but in the end there is only one project to win, and the three scientists ' biggest contribution is the energy revolution. The academic community has also been very well recognized for their awards.
