5mm UV LED, also known as ultraviolet light-emitting diode, is a type of semiconductor light source that emits light in the ultraviolet range. With its compact size and high efficiency, it has become an essential component in various industries, such as printing, coating, and medical equipment. This article will provide an in-depth introduction to the 5mm UV LED industry, covering its basic concepts, development history, application fields, and future trends.

Basic Concepts of 5mm UV LED

The 5mm UV LED is a type of semiconductor device that emits ultraviolet light. It is composed of a p-type semiconductor, an n-type semiconductor, and a p-n junction. When an electric current passes through the p-n junction, electrons and holes are generated, and recombination occurs, releasing energy in the form of ultraviolet light. The 5mm UV LED has a diameter of 5mm, which is smaller than other UV LED products, making it more suitable for space-limited applications.

Development History of 5mm UV LED

The development of UV LED technology can be traced back to the 1960s. At that time, scientists discovered that certain semiconductor materials could emit ultraviolet light when excited by electricity. However, due to the limitations of technology and materials at that time, the brightness and lifespan of UV LED were not ideal. It was not until the late 1990s that the development of UV LED technology achieved significant breakthroughs, with the birth of 5mm UV LED. With the continuous optimization of materials and structure, the performance of 5mm UV LED has been continuously improved, and its application fields have been expanded.
