Led stands for light-emitting diode which concentrates photons particles in a semiconductor and releases them in a beam of light form . Then we called it Light rays or light beam. Now in this blog, we will try to understand how it works, what it is used for it, and at last how it produces such different colors and a lot more in this blog 1st of all let's try to understand.
