Working Principle of UV LED 3W

UV LED 3W operates based on the principle of electroluminescence, which involves the generation of light through the interaction of electrons and holes in a semiconductor material. When an electric current is applied to the semiconductor, electrons and holes recombine, releasing energy in the form of photons. These photons fall within the ultraviolet (UV) spectrum, typically ranging from 10 to 400 nanometers.

The UV LED 3W diode consists of a gallium nitride (GaN) chip, which serves as the active layer, surrounded by a sapphire substrate and encapsulated in a clear epoxy lens. The GaN chip is doped with indium gallium nitride (InGaN) to achieve the desired emission characteristics. The sapphire substrate provides structural support and thermal dissipation, while the clear epoxy lens helps in focusing the emitted UV light.
