RGB LED 5mm common cathode has become an essential component in the lighting industry, offering a wide range of applications and versatile colors. This article aims to provide an in-depth introduction to the RGB LED 5mm common cathode, covering its structure, working principle, applications, advantages, and future trends.

Structure of RGB LED 5mm Common Cathode

The RGB LED 5mm common cathode is a type of LED with three separate color chips, red, green, and blue, integrated into a single package. The package is typically a 5mm diameter, which is a standard size for LEDs. The common cathode means that the three color chips share a common negative terminal, while the positive terminals are connected to the external circuit.

Working Principle of RGB LED 5mm Common Cathode

The RGB LED 5mm common cathode works by emitting light through the combination of red, green, and blue colors. When an electric current passes through the LED, it excites the electrons in the semiconductor material, causing them to recombine with the holes, releasing energy in the form of light. The intensity of the light emitted depends on the current flowing through the LED. To achieve different colors, the RGB LED 5mm common cathode can be driven by varying the intensity of the current through each color chip. For example, if only the red color chip is driven, the LED will emit red light. By adjusting the intensity of the current through the red, green, and blue color chips, a wide range of colors can be produced.
