Technology Behind RGB LED 5mm Common Cathode

RGB LED 5mm common cathode operates based on the principle of electroluminescence. When an electric current passes through the LED, it excites the electrons in the semiconductor material, causing them to recombine with electron holes. This recombination releases energy in the form of light. The color of the light emitted depends on the energy band gap of the semiconductor material used. In an RGB LED, three separate diodes are used, each emitting red, green, and blue light. By controlling the intensity of each color, a wide range of colors can be produced. The common cathode design ensures that the cathodes of all three diodes are connected together, simplifying the wiring and reducing the overall cost.
