RGB common cathode LED, also known as red, green, and blue common cathode LED, is a type of light-emitting diode that is widely used in various applications due to its color mixing capabilities. This article aims to provide an in-depth introduction to the RGB common cathode LED industry, covering its working principle, types, applications, and future trends.

Working Principle of RGB Common Cathode LED

RGB common cathode LED is a three-color LED that emits red, green, and blue light. It consists of three separate diodes, each emitting one of the three primary colors. The common cathode refers to the fact that the cathodes of all three diodes are connected together and grounded. When an electrical current is applied to the anodes, the corresponding diode emits light. The color of the light emitted by the RGB common cathode LED can be controlled by adjusting the intensity of the current flowing through each diode. By mixing the three primary colors in different proportions, a wide range of colors can be produced. This color mixing capability makes RGB common cathode LED a popular choice for applications such as lighting, displays, and decorative purposes.
