UV Diode LED: An Industry Overview

Introduction to UV Diode LED

The UV Diode LED, also known as the ultraviolet diode light-emitting diode, is a type of solid-state lighting device that emits ultraviolet light. With the rapid development of semiconductor technology, UV Diode LED has become an important part of the optoelectronic industry. It has a wide range of applications in various fields, such as medical treatment, environmental protection, and industrial production. This article will introduce the industry of UV Diode LED, including its basic principle, classification, applications, and market prospects.

Basic Principle of UV Diode LED

The UV Diode LED is a semiconductor device that emits ultraviolet light when forward biased. The core material of UV Diode LED is a semiconductor material with a direct band gap, such as gallium nitride (GaN), zinc sulfide (ZnS), and aluminum phosphide (AlP). When the forward bias voltage is applied to the semiconductor material, electrons and holes are injected into the conduction band and valence band, respectively. Through the recombination of electrons and holes, ultraviolet light is emitted.

Classification of UV Diode LED

According to the wavelength of the emitted light, UV Diode LED can be divided into three categories: UVA, UVB, and UVC. UVA has a wavelength range of 320-400nm, UVB has a wavelength range of 280-320nm, and UVC has a wavelength range of 100-280nm. The UVC UV Diode LED has the shortest wavelength and the strongest sterilization effect, while the UVA UV Diode LED has the longest wavelength and the weakest sterilization effect.
