LED (Light-Emitting Diode) is a semiconductor electronic component that can convert electric energy into light energy. The electronic components first appeared in 1962, early have a low luminosity red, after the development of other monochromatic version to emit light today in visible light, infrared and ultraviolet spectrophotometry, also increased to a luminosity. And the use of early as an indicator light, display boards, etc., with the continuous progress of technology, light-emitting diodes have been widely used in monitors, TV lighting, decoration and lighting.
In 1955, Radio Corporation America  Rubin Braunstein (GaAs) found that GaAs infrared radiation effect and other semiconductor alloys, and the United States in 1962, the Ge Corp (GE) Nick Holonyak Jr developed a visible light LED. However, LED really took off in 1990s (Nichia Chemical Industries Ltd. Japan Nichia) Nakamura Shuji in 1994 and 1995, in GaN achieved a major breakthrough in research, obtained the following Blu ray LED, Blu ray LED technology breakthrough, white LED LED officially launched the era of wide application.log on to our  official website for more :
