Introduction to UVB LED Diode

The UVB LED diode has emerged as a revolutionary technology in the lighting industry, offering numerous advantages over traditional UVB lamps. As the name suggests, UVB LED diodes emit ultraviolet B (UVB) light, which is a crucial component for various applications, including medical, agricultural, and industrial sectors. This article aims to provide an in-depth introduction to UVB LED diodes, their working principles, benefits, and applications.

Working Principles of UVB LED Diode

UVB LED diodes are solid-state devices that convert electrical energy into UVB light. They consist of a semiconductor material, typically gallium nitride (GaN), which emits UVB light when an electric current passes through it. The key components of a UVB LED diode include the LED chip, the lead frame, the encapsulant, and the heat sink. The LED chip is the core component that emits UVB light. It is made up of a p-n junction, where electrons and holes recombine, releasing energy in the form of UVB photons. The lead frame provides electrical connections to the LED chip, while the encapsulant protects the chip from external elements. The heat sink dissipates heat generated during the operation of the LED diode.
