Introducing the 5 mm RGB LED, a compact and versatile lighting solution that has become increasingly popular in various industries. These tiny, multi-color LEDs offer a wide range of applications, from simple indicator lights to complex lighting systems. In this article, we will delve into the world of 5 mm RGB LEDs, exploring their features, benefits, and applications across different sectors.

Introduction to 5 mm RGB LEDs

The 5 mm RGB LED is a type of solid-state lighting device that emits light in red, green, and blue colors. The "RGB" stands for Red, Green, and Blue, which are the primary colors that can be mixed to produce a wide spectrum of colors. These LEDs are designed to be compact, measuring just 5 mm in diameter, making them ideal for space-constrained applications.

How RGB LEDs Work

RGB LEDs work on the principle of color mixing. Each LED has three separate diodes, one for red, one for green, and one for blue. When these diodes are powered independently, they emit light of their respective colors. By controlling the intensity of each color, the LED can produce a wide range of colors. This is achieved through a process called Pulse Width Modulation (PWM), which varies the duty cycle of the electrical signal to control the brightness of each color.
