In this article, we will delve into the details of 5mm multi-color LEDs, exploring their characteristics, applications, and the market trends that drive their demand.

Introduction to 5mm Multi-Color LEDs

The 5mm multi-color LED is a type of semiconductor device that emits light in different colors by varying the composition of the semiconductor material. These LEDs are known for their small size, typically measuring 5mm in diameter, which makes them highly suitable for integration into compact electronic devices. The most common colors emitted by 5mm multi-color LEDs are red, green, blue, and yellow, but they can also produce a wide range of other colors through color mixing.

How 5mm Multi-Color LEDs Work

The working principle of a 5mm multi-color LED is based on the P-N junction, where electrons and holes recombine to release energy in the form of light. The color of the light emitted depends on the energy band gap of the semiconductor material used. For example, a red LED typically uses a gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) semiconductor, while a green LED uses a gallium nitride (GaN) or aluminum gallium nitride (AlGaN) semiconductor. Blue LEDs, which are crucial for white LED production, usually employ a zinc selenide (ZnSe) or zinc sulfide (ZnS) semiconductor.
