High power UV LED, or Ultra-Violet Light Emitting Diode, has emerged as a revolutionary technology in various industries due to its compact size, high efficiency, and long lifespan. This article aims to provide a comprehensive introduction to the high power UV LED industry, covering its history, applications, market trends, and future prospects.

History and Development of High Power UV LED

The concept of UV LED was first introduced in the 1990s, but it was not until the early 2000s that significant advancements were made in the technology. Traditional UV lamps used mercury vapor or amalgam as the light source, which were inefficient, environmentally harmful, and had a shorter lifespan. The development of high power UV LED offered a more energy-efficient, environmentally friendly, and durable alternative. The key breakthrough in high power UV LED technology came with the development of a new semiconductor material, AlGaN (Aluminum Gallium Nitride). This material enabled the production of UV LEDs with higher power output and better efficiency. Since then, the high power UV LED industry has experienced rapid growth, with numerous applications emerging in various sectors.
