scientist of the led lights

Who invented LED? Nick Holonyak, Jr. is the right person? LED (led lights) is the name of the theoretical formal light-emitting diodes, a solid light-emitting device, the solid semiconductor chip as luminescent material, the epoxy package by the carrier in the semiconductor compound release excess energy caused by photon emission , there is no filament light easy to burn, heat deposition, the light fades and other shortcomings, the direct issue of red, yellow, blue, green, blue, orange, purple, white light.

LED lighting products are the use of LEDs as a light source created by the lighting apparatus. LED is called the fourth generation of lighting source of light or green light, with energy saving, environmental protection, long life, small size, can be widely applied in various directions, display, decorative, and backlighting, general lighting and urban night scene of the field. In recent years, some of the world's economically developed countries around the development of LED (led lights) launched a fierce technology race, and for example the United States since 2000 to invest $ 500,000,000 to implement the National Semiconductor Lighting Project, the EU also announced the launch of a similar rainbow in July 2000 plan, all hope to be able to sweep away the old era incandescent bulb.

As LED is small size, fast response, long life, LED lamps, anti-shock resistance, can improve the utilization of the limited car space, especially in energy-saving issue, LEDs are becoming the choice for headlamp light

The hot issues of the LED to become a world focus, then who first invented the LED? In 1962,  Nick Holonyak, Jr., he was just a large U.S. firm General Electric Company of an ordinary researchers, to create the first a red LED, and he also believes that can emit light of other wavelengths in the future, there are many different colors of light means that the LED (led lights) and incandescent lights must be LED to replace out. Nick Holonyak, Jr. Bell Telephone Laboratories in the University of Illinois (Urbana Champaign) to obtain a Ph.D. in electrical engineering (EE), and in 1954 earned a doctorate and enter one of the most important private research institutions, he only 26 years old, filled with outstanding talent. 1954, when he entered the United States Army began to enter after the 1957 GE, continued until 1963, also invented the first a red semiconductor laser device, which is of LD, known as laser diodes, is a key component of many later CD-ROM device, a printer or copier device. Nick Holonyak, Jr. invented the LED, in 1963 from GE, as his alma mater, that is, we mentioned earlier, the University of Illinois professor of Electrical Engineering, specialized personnel training at home, as well as the morality of the scientist. Many of its students were later set up his own business in Silicon Valley, California, USA, participated in the Silicon Valley technology wave driven.Nick Holonyak, Jr. invented the brake fluid (Thyristor), also known as thyristors have to let AC, DC the ability to convert each other, with some help for the future of electrical energy storage, the world's three power through the thyristor conversion.
