The LED have become the focus of world, then who is the first invented LED ? Many people may not know ,Nick Holonyak Jr. who invented the led in 1962 was only an ordinary researchers in U.S. giant General Electric Company (General ELectricCompany, GE, also known as singular) ,he created the first red LED and he also believed that it would emit light at other wavelengths in future, which means that the LED would have a variety of different colors and the incandescent must be replaced by LED in the near future. Nick Holonyak Jr. Was got the Electrical Engineering (EE) doctorate at the University of Illinois (Urbana Champaign), he earned his PhD in 1954 and entered the American Bell Telephone Laboratories which was one of the most important private research institutions in United States, he was only 26 years old and filled with outstanding talent. In 1954, he joined the United States Army,then began to engage in GE after1957 and continued to work until 1963, he also invented the first semiconductor laser device that emitted red, which is LD and known as laser diodes , the LD is the key components of later many CD devices, printer or copier device. Nick HolonyakJr., after invented the LED, he left GE in 1963 and served as the Professor of Electrical Engineering in his alma mater, which is University of Illinois we mentioned earlier , he became the specialized trainer, as well as moral scientist. Many of his students were later established their own business in California’s Silicon Valley and involved in the Silicon Valley-driven technology wave. Nick HolonyakJr. also invented the brake fluid (Thyristor), which is known as thyristors and have the ability to convert AC, DC’s each other, which has some help for the future electricity energy storage, there are currently 3 percent of global electricity through brake fluid for conversion. His many contributions won the U.S. National Medal of Science, the U.S. National Medal of Technology, he also gained the Lemelson Prize in 2004, which is the maximum amount of bonus awards invention in United States. LED light source in the industry have called for the longevity lamps, which means light never goes out. Because LED small size, fast response, long life, LED lamps good resistance to vibration and small, can improve vehicle utilization of limited space, especially in the energy issue, LED headlamps become a new source of choice. Current oil prices soaring, when we use the ordinary light bulb headlamp, each power of 55-60 watts required, but may be as long as 3-5 after the use of LED tiles, thus saving a lot of energy and consumption. The LED lamps not only for changing the shape of the headlamp design provides greater design space and freedom, and even lead to changes in automotive styling, which is likely to be more streamlined, more fashionable. Although he is 79, he is still continuing and hopefully integrated optical switch on the chip through LED technology so that is able to complete high-speed optical in future. As the first pioneers of LED invention, Nick HolonyakJr undoubtedly is great, and now LED has developed from single light-emitting to the third-generation lighting that has gradually replaced the traditional fluorescent lighting, the LED technology has significantly rapidly developed, the LED Lighting can also combine technology, art and other fields, not just provide us with lighting, but bring us even more magical experience and convenient services, LED outdoor lighting especially has been very popular in our lives,the LED flood light as outdoor decorative lighting enjoys a great popularity in our city squares, parks, stadiums, large commercial buildings and hotel facades, stations, airports, high-altitude operations, and other outdoor venues everywhere, Lead lighting has been focusing on improving production amd R & D team and adopting qualified LED chips, drivers, enclosure and other materials to adhere to producing energy saving and affordable LED outdoor lighting that is closer to our living environment, log Lead lighting homepage www.lead-lighting.com for more LED lighting.
