RGB LED 5mm common cathode is a popular type of LED that has found wide applications in various industries due to its versatility and compact size. This article aims to provide an in-depth introduction to the RGB LED 5mm common cathode, covering its basic principles, applications, advantages, and the market trends in the industry.

Introduction to RGB LED 5mm Common Cathode

RGB LED stands for Red, Green, and Blue Light Emitting Diode, which are the three primary colors that can be mixed to produce a wide range of colors. The 5mm common cathode version of this LED has a diameter of 5mm and is designed with a common cathode configuration, meaning that the cathode (negative terminal) of all three color LEDs is connected together, while the anodes (positive terminals) are individually connected to the red, green, and blue diodes.

Basic Principles of RGB LED 5mm Common Cathode

The RGB LED 5mm common cathode operates based on the principle of electroluminescence. When an electric current passes through the diode, it excites the electrons within the semiconductor material, causing them to recombine and emit photons. The color of the light emitted depends on the energy levels of the electrons and the materials used in the semiconductor. In the case of the RGB LED, each color diode is made from a different semiconductor material. The red diode is typically made from AlGaInP (Aluminum Gallium Indium Phosphide), the green diode from GaAsP (Gallium Arsenide Phosphide), and the blue diode from GaN (Gallium Nitride). By controlling the intensity of the current through each diode, the RGB LED can produce a wide spectrum of colors.
