The seven thing is to show you the "LED" on the road to fame"

The rise of LED lighting is only half a century. From the laboratory, laboratory research projects to go to the public to achieve the most common lighting, LED lamps with environmental protection, energy saving the world, bringing a new vision of light.

In the context of the history of China's Anti Japanese War, we come back to conquer the world before the LED, to see what people and companies will bring LED into reality, into life, bring a different light.

In 1907, the British electronic engineer Landes do experiments in a silicon carbide diode, luminous phenomena are observed, this is the first time to observe luminous diode.

In 1920s, two German scientists from Wechard and Gu meal mixed with zinc sulfide copper refining yellow phosphorus, luminescence phenomena have been found in this expansion test. Unfortunately, this light, did not cause more attention.

In 1962, the United States General Electric, Meng Shandou and the Joint Laboratory of the international Business Machines Corp to develop a new type of semiconductor material that can emit red - gallium arsenide semiconductor composite materials.

In 1965, Monsanto and the Hewlett-Packard Co launched a commercially available red LED. The luminous efficiency of the LED is only 0.1 lumens / watt, while the incandescent light bulb of the effect of 15 lumens / watt is higher than it is about 150 times.

In 1994, the world's first Blu ray LED by Nichia Corporation Nakamura Shuji successfully developed. The emergence of Blu ray LED, so that the color of the LED achieve a dream.

Nakamura Shuji, invented blue LED, won the 2014 Nobel prize in physics.

In 1997, the Japanese Leah light company successfully developed a white LED. With the advent and development of white LED, LED has become a new generation of electric light source in twenty-first Century, and began to enter the lighting application stage.

During the period of 1991-2001, due to the development of material technology, chip size and shape of the LED lamp, the commercialization of LED light flux increased by nearly 30 times.

In October 7, 2014, Akasaki Yong, Tian Hao and Nakamura Shuji won the 2014 Nobel prize in physics for the invention of "efficient blue light-emitting diode".
