Introduction to SMD UV LED Diodes

SMD UV LED diodes, also known as surface mount UV LED diodes, are a type of light-emitting diode (LED) that emits ultraviolet (UV) light. Unlike traditional UV light sources, such as mercury lamps, SMD UV LED diodes are compact, durable, and energy-efficient. They are typically mounted on a printed circuit board (PCB) using surface mount technology, which allows for a smaller form factor and easier integration into various devices.

Working Principles of SMD UV LED Diodes

SMD UV LED diodes work 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 gallium nitride (GaN) or aluminum gallium nitride (AlGaN) compound, which emits UV light when excited by an electric current. The UV light emitted by the diode is then directed through a lens or reflector to concentrate the light into a specific beam pattern.
