UV diodes, also known as ultraviolet diodes, are semiconductor devices that emit ultraviolet light when an electric current passes through them. With the continuous development of technology, UV diodes have found wide applications in various fields, such as medical, environmental protection, optical communication, and food safety. This article will introduce the industry of UV diodes, including their working principle, types, applications, and market prospects.

Working Principle of UV Diodes

UV diodes are based on the principle of semiconductor physics. When the semiconductor material is excited by an electric field, electrons and holes are generated. When these electrons and holes recombine, ultraviolet light is emitted. The specific spectrum of UV light emitted by the diode depends on the material and structure of the diode.

Types of UV Diodes

UV diodes can be divided into several types according to their emission spectrum and application fields. The main types include:

• UVA Diodes: Emission spectrum range from 320nm to 400nm, mainly used in the field of environmental protection, such as water purification and air purification.
• UVB Diodes: Emission spectrum range from 280nm to 320nm, mainly used in the field of medical treatment, such as sterilization and decontamination.
• UVC Diodes: Emission spectrum range from 100nm to 280nm, mainly used in the field of food safety, such as food disinfection and water disinfection.
