Introduction to UV LEDs

UV LEDs, or ultraviolet light-emitting diodes, are solid-state lighting devices that emit light in the UV spectrum. Unlike traditional UV sources such as mercury lamps, UV LEDs offer several advantages, including lower energy consumption, longer lifespan, and compact size. The 4mm UV LED, in particular, has gained significant traction in recent years due to its ability to provide intense UV light in a very small package.

How 4mm UV LEDs Work

The 4mm UV LED operates on the principle of the PN junction, which is the interface between two different types of semiconductor materials. When an electric current is applied to the PN junction, electrons and holes recombine, releasing energy in the form of light. In the case of UV LEDs, this light falls within the ultraviolet range of the electromagnetic spectrum.

The key to the 4mm UV LED’s efficiency lies in its semiconductor material, which is carefully selected to emit UV light. Common materials used include gallium nitride (GaN), silicon carbide (SiC), and aluminum nitride (AlN). These materials are doped with impurities to create a PN junction that emits UV light when forward biased.
