Ultraviolet (UV) LED technology has emerged as a revolutionary innovation in the lighting industry, offering a wide range of applications from consumer electronics to medical and industrial sectors. As a high-efficiency and environmentally friendly lighting solution, UV LED has gained significant attention from both manufacturers and consumers alike. This article provides an in-depth introduction to the UV LED industry, covering its technology, market trends, and future prospects.

Introduction to UV LED Technology

Ultraviolet LED, also known as UV LED, is a type of solid-state lighting device that emits light in the ultraviolet (UV) spectrum. The UV spectrum ranges from 10 nm to 400 nm, with the most commonly used wavelengths being between 200 nm and 400 nm. Unlike traditional UV lamps, UV LED has several advantages, including higher efficiency, longer lifespan, and lower power consumption. The working principle of UV LED is based on the electroluminescence phenomenon. When a forward bias is applied to the semiconductor material, electrons and holes are injected into the active layer. As they recombine, energy is released in the form of photons, resulting in the emission of UV light. The semiconductor materials used in UV LED include gallium nitride (GaN), zinc sulfide (ZnS), and silicon carbide (SiC), among others.
