Introduction to UV LED Lamps

UV LED lamps are solid-state lighting devices that utilize light-emitting diodes (LEDs) to produce ultraviolet light. Unlike traditional UV lamps that use mercury vapor or other gases, UV LED lamps are more energy-efficient, compact, and have a longer lifespan. The primary advantage of UV LED technology is its ability to emit light at specific wavelengths, making it highly versatile for various applications.

Working Principles of UV LED Lamps

The working principle of UV LED lamps is based on the photoelectric effect. When an electric current is applied to a semiconductor material, electrons are excited and move to higher energy levels. When these electrons return to their original energy levels, they release energy in the form of light. In UV LED lamps, the semiconductor material is designed to emit light at ultraviolet wavelengths, typically ranging from 200 to 400 nanometers.
