What is a 4mm UV LED Diode?

A 4mm UV LED diode is a type of light-emitting diode (LED) that emits ultraviolet (UV) light at a wavelength of approximately 365 to 400 nanometers. The "4mm" refers to the diameter of the LED chip, which is a standard size for many UV LED applications. These diodes are known for their high efficiency, long lifespan, and compact design, making them ideal for various applications that require UV light.

How Does a 4mm UV LED Diode Work?

The 4mm UV LED diode operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. When an electric current is applied to the diode, electrons and holes recombine at the junction of the semiconductor material, releasing energy in the form of UV light. This process is highly efficient, as it converts a significant portion of electrical energy into light.
