5mm multi-color LED

Introduction to 5mm Multi-Color LED

The 5mm multi-color LED, also known as a 5mm RGB LED, is a compact and versatile lighting component that has gained significant popularity in various industries. These LEDs are designed to emit light in a range of colors, typically red, green, and blue, which can be mixed to produce a wide spectrum of hues. In this article, we will delve into the details of 5mm multi-color LEDs, their applications, and the technology behind them.

Basic Structure and Operation

The 5mm multi-color LED is composed of three separate chips, each emitting light in a different primary color: red, green, and blue. These chips are encapsulated within a clear, transparent, or colored plastic lens that focuses the light into a small, bright spot. The LED is powered by a low-voltage current, which excites the semiconductor material within the chips, causing electrons to recombine with electron holes and emit light. The key to the multi-color functionality lies in the ability to control the intensity of each color individually. By adjusting the current supplied to each color channel, the LED can produce different colors or even a full spectrum of hues. This is achieved through a driver circuit that allows precise control over the current flow to each color channel.

Applications of 5mm Multi-Color LEDs

The versatility of 5mm multi-color LEDs has made them suitable for a wide range of applications across various industries. Some of the most common uses include: 1.
