UV LED chips, also known as ultraviolet light-emitting diodes, have become increasingly popular in various industries due to their high efficiency, long lifespan, and environmental friendliness. This article will provide an in-depth introduction to UV LED chips, covering their definition, types, applications, advantages, and challenges in the industry. By the end of this article, you will have a comprehensive understanding of UV LED chips and their significance in modern technology.

Definition of UV LED Chip

UV LED chips are semiconductor devices that emit ultraviolet light when an electric current passes through them. They consist of a p-n junction, where the p-type and n-type materials are combined to create a forward-biased diode. When the diode is forward biased, electrons and holes recombine, releasing energy in the form of UV light.

Types of UV LED Chips

UV LED chips can be categorized into three main types based on their peak emission wavelengths: UVA, UVB, and UVC. UVA LED chips have a peak emission wavelength between 365nm and 400nm, UVB LED chips have a peak emission wavelength between 280nm and 320nm, and UVC LED chips have a peak emission wavelength between 200nm and 280nm.
