High power UV LED has emerged as a revolutionary technology in the field of lighting and has been gaining significant attention in various industries. This article aims to provide an in-depth introduction to the high power UV LED industry, covering its history, technology, applications, market trends, and future prospects.
History 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 development of high power UV LED technology. In 2002, the first high power UV LED was developed by Nichia Corporation, a Japanese company. Since then, the technology has been rapidly evolving, with continuous improvements in efficiency, output power, and cost-effectiveness.
Technology of High Power UV LED
High power UV LED technology is based on the principle of electroluminescence, where an electrical current is passed through a semiconductor material to produce light. The UV LED emits light in the ultraviolet (UV) spectrum, typically between 365 nm and 400 nm. The key components of a high power UV LED include the semiconductor material, the encapsulation material, and the heat sink.
The semiconductor material used in high power UV LED is typically a combination of gallium nitride (GaN), aluminum nitride (AlN), and silicon carbide (SiC). These materials are chosen for their ability to emit UV light and their high thermal conductivity. The encapsulation material is used to protect the semiconductor material from environmental factors and to enhance the light extraction efficiency. The heat sink is responsible for dissipating the heat generated during the operation of the LED.
