Introduction to UV LED SMD

UV LED SMD refers to a type of LED (Light Emitting Diode) that emits ultraviolet (UV) light. Unlike traditional UV lamps, UV LED SMDs are much smaller in size and consume less power. They are designed to emit light in the UV-A and UV-B spectrum, which ranges from 10nm to 400nm. The UV LED SMD market is witnessing rapid growth due to its numerous advantages over traditional UV sources.

Working Principle of UV LED SMD

The working principle of UV LED SMD is similar to that of other LEDs. It consists of a semiconductor material, typically gallium nitride (GaN), which emits light when an electric current passes through it. When the electrons and holes recombine in the semiconductor material, they release energy in the form of UV light. The UV LED SMDs are encapsulated in a transparent or semi-transparent epoxy package to protect the semiconductor material and enhance light output.
