5mm Multi Color LED – Diverse Brightness & Vibrant Colors

5mm multi-color LEDs, also known as 5mm RGB LEDs, have become increasingly popular in various industries due to their compact size, vibrant color display, and versatility. These tiny diodes pack a punch in terms of performance, making them a favorite choice for lighting, signage, and decorative applications. In this article, we will delve into the details of 5mm multi-color LEDs, exploring their features, applications, and the technology behind them.

Introduction to 5mm Multi-Color LEDs

5mm multi-color LEDs are a type of solid-state lighting device that emits light in a variety of colors. They are made by encapsulating a tiny LED chip within a clear or colored plastic lens. The LED chip itself is composed of three separate semiconductor layers, each emitting light at a specific color: red, green, and blue. By varying the intensity of light from each layer, a wide range of colors can be produced.

How 5mm Multi-Color LEDs Work

The working principle of 5mm multi-color LEDs is based on the physics of semiconductors. When an electric current is applied to the LED chip, electrons and holes recombine at the junction between the layers. This recombination releases energy in the form of photons, which correspond to different colors depending on the energy level of the electrons involved.

The red, green, and blue layers are made of different semiconductor materials that emit light at specific wavelengths. Red LEDs typically use aluminum gallium indium phosphide (AlGaInP) or aluminum gallium arsenide (AlGaAs), green LEDs use gallium nitride (GaN) or aluminum gallium nitride (AlGaN), and blue LEDs use gallium nitride (GaN) or indium gallium nitride (InGaN). By controlling the composition and thickness of these layers, the color and brightness of the emitted light can be fine-tuned.
