Introduction to LED Diodes

LED diodes, or Light Emitting Diodes, are semiconductor devices that emit light when an electric current passes through them. They are widely used in various applications, including general lighting, automotive lighting, displays, and medical devices. The key advantages of LED diodes over traditional lighting sources like incandescent bulbs and fluorescent tubes include higher efficiency, longer lifespan, and better color rendering.

Development of LED Diodes

The development of LED diodes has been a continuous process, with significant advancements made over the years. Initially, LED diodes were limited to red and yellow colors, but with the discovery of new materials and manufacturing techniques, they have expanded to include a wide range of colors, including blue, green, and even white. One of the major breakthroughs in LED diode development was the invention of the blue LED by Shuji Nakamura in the late 1980s. This discovery paved the way for the creation of white LEDs, which combined blue LEDs with phosphors that emit yellow light. The combination of these two components resulted in the emission of white light, revolutionizing the lighting industry.
