365 nm UV LED, also known as a 365 nanometer ultraviolet light-emitting diode, is a type of LED that emits light at a specific ultraviolet wavelength of 365 nanometers. This particular wavelength is highly sought after in various industries due to its unique properties and applications. In this article, we will delve into the world of 365 nm UV LEDs, exploring their technology, benefits, and the diverse range of industries where they are utilized.

Introduction to 365 nm UV LEDs

365 nm UV LEDs are a subclass of UV LEDs, which are widely used for their ability to emit light in the UV spectrum. Unlike visible light, UV light is not detectable by the human eye, but it plays a crucial role in numerous applications. The 365 nm wavelength is particularly important as it falls within the VUV (Vacuum Ultra-Violet) range, which is closer to the UVC (Ultraviolet C) region. This makes it suitable for applications requiring deep penetration and disinfection.

How 365 nm UV LEDs Work

365 nm UV LEDs work on the principle of semiconductor technology. They consist of a semiconductor material, typically gallium nitride (GaN), which emits UV light when an electric current is applied. The semiconductor material is sandwiched between two electrodes, and when a voltage is applied across the electrodes, electrons and holes recombine at the junction, releasing energy in the form of UV light. The specific wavelength of the emitted light is determined by the energy bandgap of the semiconductor material.
