Introduction to 3mm LED Diodes

3mm LED diodes are a type of light-emitting diode that measures just 3 millimeters in diameter. Despite their small size, they pack a significant punch in terms of brightness and efficiency. These diodes are commonly used in indicator lights, displays, and decorative lighting due to their versatility and ease of integration into various electronic devices.

How 3mm LED Diodes Work

At the heart of a 3mm LED diode is a semiconductor material, typically gallium nitride (GaN), gallium arsenide (GaAs), or silicon carbide (SiC). When an electric current passes through the semiconductor, it excites electrons, which then recombine with electron holes, emitting light in the process. The color of the light produced depends on the type of semiconductor material used and the energy band gap.
