UV C LED diode, as a cutting-edge technology in the field of lighting, has been gaining increasing attention in recent years. With its high efficiency, low energy consumption, and strong penetration ability, UV C LED diode has become a promising solution for various applications, such as sterilization, disinfection, and surface treatment. This article will introduce the industry of UV C LED diode, including its definition, working principle, applications, market status, and future development trends.

Definition and Classification of UV C LED Diode

UV C LED diode refers to a semiconductor light-emitting device that emits ultraviolet light with a wavelength between 200nm and 280nm. It is divided into three types according to the emission wavelength: UVC (200-280nm), UVB (280-320nm), and UVA (320-400nm). Among them, UVC LED diode has the strongest sterilization effect and is the most widely used in the industry.

Working Principle of UV C LED Diode

The working principle of UV C LED diode is based on the photoelectric effect of semiconductor materials. When the forward voltage is applied to the PN junction of the diode, electrons and holes are separated in the semiconductor material. When these electrons and holes recombine, ultraviolet light is emitted. The energy of the emitted light is determined by the band gap of the semiconductor material, and the shorter the band gap, the shorter the wavelength of the emitted light.

Applications of UV C LED Diode
