LED bulb origin
Jan 04, 2018

Nick - Holoniagg is a general researcher at General Electric Company in the United States. In 1962 he developed the world's first LED-light-emitting diodes. He believes that it will certainly be possible to obtain red light as well as light of other colors. In 1963, he wrote in the United States, "Reader's Digest," said the future of lighting and display areas will be the world of light-emitting diodes!


The year after Holoniak invented the light-emitting diode, he left General Electric to become a professor of electrical engineering at the University of Illinois. He wants to train more students through education, through them to improve and promote the application of light-emitting diodes. Many of the physicists that he teaches at the university have become entrepreneurs, chief executives, or researchers. And the invention has been successfully improved after the market of light-emitting diodes.


In 1963, Holoniak invented the world's first red-emitting semiconductor laser. This laser diode is now a key component for CDs, DVDs, players, laser printers and copiers. From the 70s of last century, Holoniak began the work of extending the light-emitting diode light spectrum to invisible light infrared. Infrared diode will not only change the long-distance communication system, will also change the appearance of the computer. Now nearly eighty years old Holloniag is still pursuing the intention of using light-emitting diode method, a large number of optical switches integrated in the chip, and then realize the dream of light computer.


Holoniak contribution is to give future generations a new inspiration, so that the study of new light sources, new devices opened up new avenues. People have made into yellow, green, blue, white and other different colors of light-emitting diodes. Nowadays giant fans made of light-emitting diodes are used all over the world to display the figures clearly during the daytime. The traffic light and all the lights within the car is almost full use of light-emitting diodes.
