Introduction to 254 nm UV Light LED

The 254 nm UV light LED is a type of solid-state lighting device that emits ultraviolet light at a very short wavelength. Unlike visible light LEDs, which emit light in the range of 380 to 780 nanometers, UV LEDs produce light that is outside the visible spectrum. The 254 nm wavelength falls within the UVC range of the ultraviolet spectrum, which is known for its germicidal properties.

Working Principle of 254 nm UV Light LED

The working principle of a 254 nm UV light LED is based on the quantum dot effect. Quantum dots are semiconductor particles with a diameter of 1 to 10 nanometers. When an electric current is applied to the LED, the electrons and holes recombine within the quantum dots, releasing energy in the form of UV light. The 254 nm wavelength is achieved by carefully designing the composition and structure of the quantum dots.
