What is the LED

A Light-Emitting Diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices, and are increasingly used for lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light. However, modern versions are available across the visible, ultraviolet and infrared wavelengths, with very high brightness. Want to know how exactly it works? Find it in the below link…
