This article aims to provide an in-depth introduction to RGB LED 5mm common cathode, covering its working principle, advantages, applications, and future trends.

Introduction to RGB LED 5mm Common Cathode

RGB LED 5mm common cathode, also known as a red, green, and blue LED with a common cathode, is a type of LED that emits three primary colors: red, green, and blue. These colors can be mixed in various proportions to produce a wide range of colors. The "common cathode" term refers to the fact that the cathode (negative terminal) of all three LEDs is connected together, while the anodes (positive terminals) are individually connected to a control circuit.

Working Principle of RGB LED 5mm Common Cathode

The working principle of RGB LED 5mm common cathode is based on the phenomenon of electroluminescence. When an electric current passes through the semiconductor material of the LED, it emits light. In the case of RGB LED, each LED emits a specific color due to the different semiconductor materials used: - Red LED: AlInGaP or AlGaInP - Green LED: GaAsP or GaP - Blue LED: GaN or InGaN By controlling the current passing through each LED, the intensity of each color can be adjusted, allowing for a wide range of color mixing possibilities.
