265nm LED, also known as ultraviolet LED, has emerged as a revolutionary technology in the field of lighting and optoelectronics. With its ability to emit light at a shorter wavelength, this innovative LED has opened up new possibilities in various applications, including medical, industrial, and consumer sectors. This article aims to provide a comprehensive overview of the 265nm LED industry, exploring its technology, applications, challenges, and future prospects.

Technology and Working Principle

The 265nm LED is a type of light-emitting diode that emits light at a wavelength of 265 nanometers, which falls within the ultraviolet (UV) spectrum. Unlike traditional LEDs that emit visible light, 265nm LEDs produce UV light, which is invisible to the human eye. The working principle of a 265nm LED is similar to that of other LEDs, with a few key differences. Firstly, the 265nm LED uses a different semiconductor material, typically gallium nitride (GaN), to achieve the desired emission wavelength. GaN is known for its excellent UV emission properties, making it an ideal choice for 265nm LED production. Secondly, the structure of a 265nm LED is designed to enhance the emission of UV light, ensuring higher efficiency and brightness. The key components of a 265nm LED include the semiconductor material, a p-n junction, and an encapsulation layer. When an electric current is applied to the p-n junction, electrons and holes recombine, releasing energy in the form of UV light. The encapsulation layer is crucial in protecting the LED from external factors, such as moisture and temperature, and improving its lifespan.
