UV LEDs, or ultraviolet light-emitting diodes, have emerged as a revolutionary technology in various industries due to their ability to produce high-intensity, focused ultraviolet light. These diodes have become increasingly popular for their efficiency, longevity, and versatility. This article aims to provide a comprehensive introduction to the UV LED industry, exploring its applications, market trends, technological advancements, and future prospects.

Introduction to UV LEDs

UV LEDs are semiconductor devices that emit light in the ultraviolet (UV) portion of the electromagnetic spectrum, typically between 10 and 400 nanometers (nm). Unlike traditional UV sources, such as mercury lamps, UV LEDs offer several advantages, including lower energy consumption, longer lifespan, and the ability to produce a narrow bandwidth of light.

UV LEDs are created by doping a semiconductor material, such as gallium nitride (GaN), with impurities that create an excess of electrons or holes. When an electric current is applied to the diode, the excess electrons and holes recombine, releasing energy in the form of UV light.
