RGB common cathode LED, also known as red, green, and blue common cathode LED, is a type of light-emitting diode that emits three primary colors: red, green, and blue. It is widely used in various fields such as displays, lighting, and decoration. In this article, we will introduce the industry of RGB common cathode LED, including its working principle, classification, application, and future development.

Working Principle of RGB Common Cathode LED

RGB common cathode LED is a kind of three-color LED, which can emit red, green, and blue light by controlling the current of each color channel. The working principle of RGB common cathode LED is based on the principle of color mixing. When red, green, and blue light are mixed, they can produce various colors. The following is a brief introduction to the working principle of RGB common cathode LED: 1. The RGB common cathode LED consists of three diodes, each emitting red, green, and blue light respectively. 2. The three diodes are connected to the anode and cathode in a common cathode configuration. 3. By controlling the current of each color channel, the brightness and color of the emitted light can be adjusted. 4. When the current of the red, green, and blue channels is adjusted appropriately, the desired color can be obtained through color mixing.

Classification of RGB Common Cathode LED

RGB common cathode LED can be classified according to different criteria, such as color, size, and packaging. The following is a brief introduction to the classification of RGB common cathode LED: 1. According to color, RGB common cathode LED can be divided into single-color LED, dual-color LED, and full-color LED. Single-color LED emits only one color, such as red, green, or blue. Dual-color LED emits two colors, such as red and green or red and blue. Full-color LED emits all three colors: red, green, and blue. 2. According to size, RGB common cathode LED can be divided into SMD (Surface Mount Device) LED, COB (Chip on Board) LED, and other types of LED. 3. According to packaging, RGB common cathode LED can be divided into through-hole packaging, surface mount packaging, and other types of packaging.
