On Tuesday, a US and two Japanese scientists won 2014 Nobel Prize in Physics for inventing a new energy source.
Efficient environmental protection-
Friendly light source, resulting in the generation of modern LED bulbs.
Japanese and Japanese Chi Minh and Tian Ye Hongzhiborn U. S.
Secretary nak won the prize for developing blue light-LEDs (LED)—
Now allows manufacturers to produce missing parts of white productslight lamps.
The arrival of this lamp is changing the lighting mode in the home and workplace, providing a longer lighting time
At the end of the 19 th century, Joseph Swan and Thomas Edison pioneered a durable and more effective alternative to incandescent lamps.
\"The red and green LEDs have been around for a long time, but the blue is really gone.
Thanks to the blue LED, we can now get a white light source with very high energy efficiency and very long life, \"said Per Delsing, a member of the Royal Swedish Academy of Sciences, at a press conference.
The award is a remarkable example of the actual discovery of the award, compared to last year\'s physics prize, where scientists predict the existence of the Higgs particle, this explains how the mass of the basic matter is obtained to form stars and planets.
\"Incandescent lamps lit in the 20 th century;
The 21st century will be lit up by LED lights, \"the college said in a statement granting the crown of 8 million Sweden ($1. 1 million)prize.
Frances Sanders, director of the British Institute of Physics, said the turn offered potential for huge energy savings.
\"According to the calculation, 20% of the world\'s electricity is used for lighting, and the best use of LED lighting can reduce this ratio to 4%.
Research by Akasaki, Amano and nak has made this possible, and this award recognizes this contribution, \"she said.
Chiaki, a University of may Qiao in Japan, is a professor at Nagoya University.
Nak studied at the University of California, Santa Barbara.
Nak was contacted by phone in the middle of the night and he said about the award: \"It\'s incredible.
In a later statement, he added: \"It\'s very satisfying to see my dream of LED lighting come true.
\"Blue invented by the village
LEDs worked at the unlisted company Nichia, but by 2004 the company received almost nothing, when the Tokyo court ordered Nichia to pay him a record 20 billion yen ($185 million).
The company appealed and nak settled for $8 million.
Colin Humphries, an expert at the University of Cambridge, is working on next-
Generation LED lighting, the ability of three scientists to solve the blue light problem when others fail is a huge achievement.
\"The efficient blue LEDs they invented paved the way for the development of bright, cost-effective, important energy-saving white lighting,\" he said . \".
In addition to lighting buildings, LED bulbs are also changing lights in cars, and the technology is also used as a light source on smartphones and computer screens.
The boom in LED is subverting the traditional lighting industry, and General Electric, one of the biggest players, predicts that by 2020, LED will account for about 70% of the $100 billion market, compared, in 2012, 18% per cent.
LED lights are 10 times longer than fluorescent lamps and 100 times longer than traditional incandescent lamps.
Competition to develop more advanced, more economical versions brings opportunities and challenges to the company and helps drive change
In this industry.
Osram was listed last year by its former parent company Siemens, and Philips also plans to split its lighting department after producing light bulbs in 123.
As the winner of the physics prize, the three new winners joined some of the big names in science, such as Einstein, Niles ball and Pierre and Mrs. Mary Curie\'s team of couples.
The award is also a boost to Japan\'s reputation for science, as it has been tarnished by a reputable high-profile stem cell study that seems to provide an organ for replacing damaged cells and even cultivating new humans.
Haruko Obokata, author of the study, was told by Waseda University that it would deprive her of her PhD unless she corrected it within a year.
Obokata\'s discovery was originally advertised as a game.
But soon, research and research found that problems with the plagiarism and fabrication of parts of the paper appeared.
Physics is the second Nobel Prize winner this year.
According to the will of the inventor of explosives and business tycoon Alfred Nobel, the awards were first awarded in 1901 in recognition of achievements in science, literature and peace.
