This article provides an in-depth introduction to UV LED diodes, exploring their working principles, applications, market trends, and future prospects.

Introduction to UV LED Diodes

UV LED diodes are solid-state devices that emit ultraviolet light when an electric current passes through them. Unlike traditional UV lamps that use mercury vapor or other harmful substances, UV LED diodes are free from toxic materials and are considered more environmentally friendly. The compact size and low power consumption of UV LED diodes make them highly suitable for a wide range of applications.

Working Principles of UV LED Diodes

UV LED diodes work on the principle of electroluminescence. When an electric current is applied, electrons in the semiconductor material recombine with electron holes, releasing energy in the form of light. The emitted light is in the ultraviolet range, which is characterized by wavelengths shorter than visible light. The specific wavelength of the emitted light depends on the semiconductor material used in the diode.
