An LED (Light Emitting Diode) is a semiconductor device that emits light when an electric current passes through it. Unlike traditional bulbs that generate light by heating a filament, LEDs produce light through a process called electroluminescence—where electrons and holes recombine at a junction, releasing energy as photons.
This makes LEDs highly efficient, durable, and versatile, with applications ranging from consumer electronics and industrial systems to automotive lighting and digital displays
How LEDs Work
LEDs are built from two types of semiconductor material:
N-type (extra electrons)
P-type (extra holes)
