This article aims to provide an in-depth introduction to the 4mm UV LED diode, its applications, advantages, and the impact it has on various industries.

What is a 4mm UV LED Diode?

A 4mm UV LED diode is a semiconductor device that emits ultraviolet (UV) light when an electric current is applied. The "4mm" refers to the diameter of the LED chip, which is a standard size for many UV LED applications. These diodes operate at a lower voltage and emit light at a shorter wavelength compared to visible light LEDs, making them ideal for specific applications that require UV radiation.

How Does a 4mm UV LED Diode Work?

The working principle of a 4mm UV LED diode is based on the photoelectric effect. When an electric current is applied to the diode, electrons are excited and move to higher energy levels. As these electrons return to their original energy levels, they release energy in the form of UV light. The 4mm size of the diode allows for a compact and efficient design, making it suitable for various applications.
