3mm UV LED, also known as ultra-violet light-emitting diode, is a type of semiconductor device that emits UV light when an electric current passes through it. With its compact size and high efficiency, it has been widely used in various industries, such as printing, coating, and medical fields. This article aims to introduce the industry of 3mm UV LED, including its development history, application fields, and market prospects.
Development History of 3mm UV LED
The invention of the UV LED can be traced back to the early 20th century. In 1917, an American physicist, Theodore Maiman, successfully developed the first solid-state UV LED, which used a diamond crystal as the emitter. However, due to the high cost and poor performance of the material, the application of UV LED was limited. In the 1980s, with the development of semiconductor technology, UV LED began to be used in industrial fields. Since then, the market demand for UV LED has continued to grow, and the technology has been constantly improved.
In the 1990s, the development of UV LED was significantly accelerated. At this time, the technology of UV LED was mainly based on gallium nitride (GaN) as the active layer. Compared with the diamond crystal, GaN has better performance and lower cost. In 2000, the first 3mm UV LED was successfully developed by a Japanese company. Since then, the size of UV LED has been continuously reduced, and the market has been expanding rapidly.
