What is a 5mm UV LED Diode?

A 5mm UV LED diode is a type of light-emitting diode (LED) that emits ultraviolet (UV) light with a diameter of approximately 5mm. These diodes are designed to provide a focused and intense UV light source, which is ideal for a wide range of applications, including curing, disinfection, and illumination.

How UV LED Diodes Work

UV LED diodes operate on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in UV LED diodes is typically a compound semiconductor, such as gallium nitride (GaN), which can emit UV light at a specific wavelength depending on the composition and structure of the material.
