Introduction to UV LED Diodes

UV LED diodes are solid-state lighting devices that emit ultraviolet light. Unlike traditional UV lamps, which often use mercury vapor or other gases, UV LED diodes are more energy-efficient, have a longer lifespan, and are environmentally friendly. The 365nm wavelength is part of the UVC (ultraviolet C) spectrum, which is known for its germicidal properties.

How UV LED Diodes Work

UV LED diodes operate by using a semiconductor material that emits UV light when an electric current passes through it. The semiconductor material typically consists of a gallium nitride (GaN) crystal, which is doped with indium or gallium to create a p-n junction. When an electric current is applied, electrons recombine with electron holes, releasing energy in the form of UV light.
