This article aims to provide an in-depth introduction to the UV LED diode industry, exploring its evolution, applications, market trends, and future prospects.

Introduction to UV LED Diodes

UV LED diodes are solid-state devices that emit UV light when an electric current passes through them. They are composed of a semiconductor material, typically gallium nitride (GaN), indium gallium nitride (InGaN), or zinc sulfide (ZnS), which emits UV light when excited by an electric current. Unlike traditional UV lamps, UV LED diodes are more energy-efficient, compact, and have a longer lifespan. They have become a preferred choice for numerous applications due to these advantages.

Evolution of UV LED Diodes

The development of UV LED diodes has a long history, dating back to the early 20th century. However, it was not until the late 1990s that significant progress was made in the field. Researchers at Nichia Corporation in Japan achieved a breakthrough by developing a high-brightness, blue LED with a gallium nitride-based structure. This breakthrough paved the way for the development of UV LED diodes, as blue light can be used to excite UV-emitting materials. In the early 2000s, the UV LED market started to grow, with applications in curing inks and adhesives, sterilization, and counterfeit detection. Over the past two decades, the technology has continued to advance, with improvements in efficiency, brightness, and color range. Today, UV LED diodes are widely used in various industries, and the market is expected to continue growing in the coming years.
