Diode LED 5mm has become a staple in the lighting industry, offering a compact and efficient solution for various applications. This article delves into the world of 5mm diode LEDs, exploring their characteristics, applications, and the technological advancements that have made them a favorite among designers and engineers.

Introduction to Diode LED 5mm

The 5mm diode LED, also known as a surface mount device (SMD), is a small, circular light-emitting diode that measures just 5mm in diameter. Despite its small size, it packs a significant punch in terms of brightness and efficiency. These LEDs are commonly used in indicator lights, displays, and decorative lighting due to their compact design and high luminosity.

How Diode LED 5mm Works

A diode LED 5mm operates on the principle of the p-n junction, where electrons and holes recombine to emit light. When an electric current is applied to the diode, electrons from the n-type semiconductor are drawn to the p-type semiconductor, where they recombine with holes. This recombination process releases energy in the form of light. The color of the light emitted by a 5mm diode LED is determined by the material used in the semiconductor layer. For example, a red LED is made with a gallium arsenide (GaAs) layer, while a blue LED uses a gallium nitride (GaN) layer. The color spectrum ranges from red to blue, with white LEDs typically being a combination of red, green, and blue diodes.
