This article will introduce the industry of LED high power light emitting diode, including its development history, market status, technology trends, and application prospects.

Development History of LED High Power Light Emitting Diode

LED, as a semiconductor light-emitting device, was first discovered by O. Stern and J. L. Slichter in 1917. However, due to the limitations of technology at that time, LED had not been widely used. In the 1960s, the development of LED technology was promoted by the discovery of GaAs-based LED. In the 1970s, the red LED was developed, which marked the beginning of the commercial application of LED. Since then, LED technology has developed rapidly, and the luminous efficiency and color gamut of LED have been greatly improved. In the 1980s, the development of LED technology entered a new stage. The invention of the blue LED by Shuji Nakamura in 1993 laid the foundation for the development of white LED. In 2014, the Nobel Prize in Physics was awarded to Shuji Nakamura, Isamu Akasaki, and Hiroshi Amano for their contributions to the development of LED technology. The development of LED technology has promoted the transformation and upgrading of the lighting industry, and has also had a significant impact on other fields.
