Introduction to 3mm LED Diode

The 3mm LED diode is a type of light-emitting diode (LED) that measures approximately 3mm in diameter. Despite its small size, it packs a significant punch in terms of brightness and efficiency. These diodes are commonly used in indicator lamps, displays, and decorative lighting due to their compact form factor and energy-saving properties.

How Does a 3mm LED Diode Work?

A 3mm LED diode operates on the principle of electroluminescence. When an electric current passes through the semiconductor material within the diode, it excites the electrons, causing them to recombine with electron holes. This recombination releases energy in the form of photons, which produce light. The small size of the 3mm diode allows for a high density of diodes to be packed into a limited space, making it ideal for applications requiring numerous indicator lights or pixelated displays.
