Introduction to 3mm LED

The 3mm LED, also known as a surface mount LED (SMD), is a tiny light-emitting diode with a diameter of just 3mm. Despite its small size, it packs a powerful punch, offering high brightness, low power consumption, and a wide range of color options. These characteristics make it an ideal choice for a variety of applications, from indicator lights to decorative lighting.

How Does a 3mm LED Work?

A 3mm LED works on the principle of electroluminescence, which is the process of light emission when electrons recombine with electron holes in a semiconductor material. When a voltage is applied to the LED, electrons and holes are forced together, releasing energy in the form of light. The color of the light emitted depends on the semiconductor material used in the LED.
