Introduction to 5mm Purple LED

The 5mm purple LED is a semiconductor device that emits light when an electric current is applied. It consists of a gallium nitride (GaN) or gallium phosphide (GaP) chip, encapsulated in a clear or purple plastic lens. The purple color is achieved by doping the semiconductor material with elements such as indium or arsenic.

The 5mm purple LED is designed to operate at a forward voltage of around 2.8 to 3.2 volts and a forward current of 20mA. This compact size makes it ideal for use in various applications where space is limited. The LED emits light with a color temperature of around 4000K to 5000K, providing a bright and vibrant purple hue.
