Introduction to 265nm UV LED Industry

What is a 265nm UV LED?

A 265nm UV LED, or ultraviolet light-emitting diode, is a type of semiconductor device that emits ultraviolet light at a wavelength of 265 nanometers. UV LEDs are widely used in various applications due to their compact size, low power consumption, and high efficiency. The 265nm wavelength falls within the deep UV (UVC) range, which is particularly effective for sterilization, water purification, and other disinfection processes.

How does a 265nm UV LED Work?

The working principle of a 265nm UV LED is similar to that of other LEDs. It consists of a semiconductor material, typically gallium nitride (GaN), which emits light when an electric current passes through it. The 265nm UV LED uses a specific type of GaN that can emit UV light at the desired wavelength. When the electric current is applied, the electrons and holes recombine within the semiconductor material, releasing energy in the form of photons. These photons are then emitted as UV light.
