The high power UV LED market is witnessing rapid growth due to the increasing demand for energy-efficient and environmentally friendly lighting solutions.

How High Power UV LED Works

High power UV LED technology operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The UV LED emits light in the ultraviolet range, typically between 365 and 400 nanometers (nm). The key components of a high power UV LED include a semiconductor chip, a lead frame, a die bond, and a phosphor coating.

The semiconductor chip is the heart of the UV LED, where the electroluminescence process takes place. The lead frame provides electrical connections to the chip, while the die bond ensures a secure attachment of the chip to the lead frame. The phosphor coating is applied to convert the UV light emitted by the LED into visible light, making it more useful for various applications.
