UV Diode LED, or Ultraviolet Diode LED, is a type of light-emitting diode that emits ultraviolet light. With the rapid development of technology, UV Diode LED has been widely used in various fields, such as medical treatment, food safety, environmental protection, and industrial production. This article will introduce the industry of UV Diode LED, including its basic principles, application fields, market prospects, and challenges.

Basic Principles of UV Diode LED

UV Diode LED is a semiconductor device that emits ultraviolet light through the recombination of electrons and holes. The core material of UV Diode LED is usually gallium nitride (GaN), which has excellent optoelectronic properties. The working principle of UV Diode LED is as follows: 1. Electron-hole recombination: When the forward voltage is applied to the UV Diode LED, electrons and holes are injected into the active layer from the p-type and n-type regions, respectively. The electrons and holes recombine in the active layer, releasing energy in the form of ultraviolet light. 2. Light-emitting process: The ultraviolet light emitted by the recombination process is then coupled out through the p-type and n-type regions, and finally radiated out through the lens or light guide plate.

Application Fields of UV Diode LED

UV Diode LED has a wide range of application fields due to its unique properties. The following are some typical application fields: 1. Medical treatment: UV Diode LED can be used for sterilization and disinfection of medical equipment, surgical instruments, and operating rooms.
