Uv light diode, a key component in various industries, has been widely used in the past few years. As a high-efficiency and stable light source, UV light diode plays an important role in the development of various applications. This article will introduce the industry of UV light diode, including its working principle, types, applications, and market trends.

Working Principle of UV Light Diode

The working principle of UV light diode is based on the photoelectric effect. When the UV light diode is forward biased, electrons and holes are generated in the p-n junction, and the electrons are injected into the n-type semiconductor. As the electrons move through the semiconductor, they collide with atoms and produce UV light through the process of energy release. The UV light emitted by the diode has a short wavelength, high energy, and strong penetration ability.

Types of UV Light Diodes

According to the emission wavelength, UV light diodes can be divided into three types: near-ultraviolet (NUV), middle-ultraviolet (MUV), and far-ultraviolet (FUV). NUV diodes have a wavelength range of 365-400nm, MUV diodes have a wavelength range of 280-365nm, and FUV diodes have a wavelength range of 100-280nm. The emission wavelength of UV light diode determines its application field.
