In this article, we will delve into the details of the 275nm UV LED, its working principle, benefits, applications, and the future of this innovative technology.

Working Principle of 275nm UV LED

The 275nm UV LED operates on the principle of electroluminescence, which is the process of light emission from a material when it is excited by an electric current. Unlike traditional UV light sources that use mercury vapor or other gases, the 275nm UV LED uses a semiconductor material that emits UV light when an electric current passes through it. The semiconductor material used in 275nm UV LEDs is typically a gallium nitride (GaN) compound, which has been engineered to emit light at the desired 275nm wavelength. When the LED is powered on, the electric current excites the electrons in the GaN material, causing them to move to higher energy levels. As these electrons return to their original energy levels, they release energy in the form of UV light.
