Introduction to 8mm UV LED Diode

Understanding 8mm UV LED Diode

The 8mm UV LED diode is a specialized type of light-emitting diode (LED) that emits ultraviolet (UV) light at a wavelength of approximately 365-400 nanometers. This diode is widely used in various applications due to its compact size, high efficiency, and long lifespan. In this article, we will explore the 8mm UV LED diode, its working principle, applications, and the benefits it offers over traditional UV sources.

Working Principle of 8mm UV LED Diode

An 8mm UV LED diode operates based on the principle of the photoelectric effect. When an electric current is applied to the diode, electrons and holes are generated in the semiconductor material. As these electrons recombine with the holes, energy is released in the form of photons. The energy released corresponds to the bandgap of the semiconductor material, which determines the wavelength of the emitted light. In the case of 8mm UV LED diodes, the semiconductor material used is typically gallium nitride (GaN), gallium phosphide (GaP), or zinc sulfide (ZnS). These materials have a bandgap that allows them to emit UV light at the desired wavelength. The 8mm size refers to the diameter of the diode, which is relatively small compared to other UV LED diodes.
