What is a 365 nm UV LED?

A 365 nm UV LED is a type of light-emitting diode that emits ultraviolet light at a wavelength of 365 nanometers. UV LEDs are semiconductor devices that produce light when an electric current passes through them. Unlike traditional UV lamps that use mercury vapor or other chemicals to generate UV light, UV LEDs are solid-state devices that are more energy-efficient, durable, and environmentally friendly.

Working Principle

The working principle of a 365 nm UV LED is based on the quantum mechanical phenomenon of electroluminescence. When an electric current is applied to the LED, electrons and holes recombine in the semiconductor material, releasing energy in the form of photons. The energy released corresponds to the energy difference between the conduction band and the valence band of the semiconductor material, resulting in the emission of UV light at a specific wavelength.
