Introduction to 3mm Purple LEDs

The 3mm purple LED, also known as the 3mm purple light-emitting diode, is a compact and efficient light source that has gained significant popularity in various industries. This article delves into the details of 3mm purple LEDs, exploring their features, applications, and the technology behind them.

What is a 3mm Purple LED?

A 3mm purple LED is a type of semiconductor diode that emits light in the purple color spectrum. It is characterized by its small size, which measures just 3mm in diameter. The purple color is achieved by the specific composition of the semiconductor material used in the LED, which emits light at a wavelength of approximately 400 to 450 nanometers.

How Does a 3mm Purple LED Work?

The working principle of a 3mm purple LED is based on the semiconductor technology. When an electric current is applied to the LED, electrons and holes recombine at the junction of the semiconductor material. This recombination process releases energy in the form of light. The color of the light emitted depends on the energy bandgap of the semiconductor material.

In the case of a 3mm purple LED, the semiconductor material is typically a phosphor-coated gallium nitride (GaN) or a gallium arsenide (GaAs) compound. The phosphor coating is responsible for converting the blue light emitted by the semiconductor into purple light by absorbing some of the blue light and emitting it in the purple spectrum.
