Introduction to 3mm Through Hole LED Industry

Understanding 3mm Through Hole LED

The 3mm through hole LED, also known as the 3mm LED, is a type of light-emitting diode that is designed with a diameter of 3mm. This size is particularly popular in the electronics industry due to its compact design and versatility. The "through hole" aspect of this LED refers to the way it is mounted on a printed circuit board (PCB). Unlike surface mount devices (SMDs), through hole LEDs have leads that extend through the PCB, providing a stable and durable connection. These LEDs are widely used in various applications, including indicator lights, display modules, and decorative lighting. Their small size and bright output make them ideal for use in space-constrained environments. Additionally, the through hole design offers ease of assembly and repair, which is crucial in many electronic devices.

How 3mm Through Hole LEDs Work

3mm through hole LEDs are made up of a semiconductor material, typically gallium arsenide (GaAs), gallium nitride (GaN), or silicon carbide (SiC). When an electric current is applied to the LED, the semiconductor material emits light in the visible spectrum. The color of the light produced depends on the type of semiconductor material used and the doping process. The LED's structure consists of a p-n junction, where electrons and holes recombine, releasing energy in the form of light. The size of the LED, in this case, 3mm, determines the amount of light it can produce. Generally, smaller LEDs have lower brightness, while larger ones can emit more light.
