Working of LED

An LED (light-emitting diode) is an invention that’s used when bright, low power and low-heat lights are needed. In a diode, electrons rise to and fall from precise energy levels. When an electron falls to a lower energy level, light energy is emitted. It’s the size of the fall (the gap) that decides the frequency of the light. The aim is to show the functioning of a Light Emitting Diode (LED)
