How LED (Light Emitting Diode) Works? [3D Animation]

LED lights are widely used today, but how do they work? At their core is a semiconductor chip, typically made of aluminum-gallium-arsenide. When doped with additional atoms, the material becomes more conductive. N-type material has extra electrons, while P-type material has extra holes. When these are combined in a diode, electricity can only flow in one direction.
Applying voltage removes the depletion zone, allowing electrons to move freely, generating light as they fall into holes. The light produced is typically blue, but with a phosphorus layer, it becomes white. RGB LEDs work similarly, with three diodes for red, green, and blue, offering a wide range of colors by adjusting voltage.
