4mm UV LED Diode: A Pioneering Technology in the Lighting Industry

Introduction to UV LED Diodes

UV LED diodes, also known as ultraviolet light-emitting diodes, have emerged as a revolutionary technology in the lighting industry. These diodes emit light in the ultraviolet (UV) spectrum, which ranges from 10 nm to 400 nm. The 4mm UV LED diode, in particular, has gained significant attention due to its compact size, high efficiency, and versatility. This article aims to provide an in-depth introduction to the 4mm UV LED diode, its applications, and its impact on various industries.

How UV LED Diodes Work

UV LED diodes operate 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 compound semiconductor, such as gallium nitride (GaN), zinc sulfide (ZnS), or silicon carbide (SiC). These materials have a direct bandgap, which allows them to efficiently convert electrical energy into UV light. The 4mm UV LED diode is a type of UV LED with a diameter of 4 millimeters. It is designed to emit UV light with a specific wavelength, which can range from 365 nm to 400 nm. The size of the diode is crucial for its applications, as it determines the amount of light output and the spatial distribution of the emitted light.
