RGB common cathode LED, also known as red, green, and blue common cathode LED, is a type of light-emitting diode that emits light in the red, green, and blue colors. It is widely used in various fields such as household appliances, automotive lighting, and digital displays. This article will introduce the industry of RGB common cathode LED, including its working principle, application fields, market trends, and future development prospects.

Working Principle of RGB Common Cathode LED

RGB common cathode LED is a three-color LED that can emit red, green, and blue light. The working principle is based on the principle of color mixing. When the red, green, and blue light are mixed in different proportions, they can produce various colors. The common cathode refers to the fact that the cathode of the red, green, and blue LED is connected together, and the anode is connected to the external circuit. The RGB common cathode LED is composed of three LED chips, each of which emits red, green, and blue light. The three chips are encapsulated in a common cathode package. When the anode voltage is applied to the external circuit, the current flows through the LED chips, and the light is emitted according to the color of the chip. By adjusting the current through each LED chip, the brightness and color of the light can be controlled.
