Introduction to 3mm Purple LED

The 3mm purple LED, also known as the 3mm purple light-emitting diode, is a type of semiconductor device that emits purple light when an electric current passes through it. It is part of the 3mm LED family, which includes other colors such as red, green, blue, and yellow. The 3mm size refers to the diameter of the LED's lens, making it a compact and versatile lighting solution.

How 3mm Purple LED Works

The 3mm purple LED operates based on the principle of electroluminescence. When an electric current is applied to the semiconductor material, it excites the electrons, causing them to recombine with electron holes. This recombination releases energy in the form of light. In the case of purple LEDs, the semiconductor material used is typically a mixture of aluminum gallium indium phosphide (AlGaInP) and gallium nitride (GaN), which emits purple light when excited.
