Introduction to 8mm UV LED

What is an 8mm UV LED?

The 8mm UV LED, also known as an ultra-violet light-emitting diode, is a compact and efficient light source that emits light in the ultraviolet (UV) spectrum. Measuring just 8mm in diameter, these LEDs are designed to provide a concentrated and focused UV light output. The UV spectrum ranges from 10nm to 400nm, with 8mm UV LEDs typically emitting light in the range of 365nm to 400nm. These devices are widely used in various applications, including curing adhesives, disinfection, and industrial processes.

Working Principle of 8mm UV LED

The working principle of an 8mm UV LED is based on the semiconductor technology. When a forward voltage is applied across the diode, electrons and holes recombine at the p-n junction, releasing energy in the form of photons. The wavelength of the emitted light depends on the composition of the semiconductor material used in the diode. In the case of 8mm UV LEDs, the semiconductor material is typically a gallium nitride (GaN) or a silicon carbide (SiC) compound, which allows for efficient UV light emission.
