RGB Common Cathode LED: Ultimate Guide & Benefits

RGB common cathode LED, also known as red, green, and blue common cathode LED, is a type of light-emitting diode (LED) that emits three primary colors of light: red, green, and blue. This kind of LED is widely used in various applications, such as electronic devices, automotive lighting, and decorative lighting. In this article, we will explore the features, applications, and market trends of RGB common cathode LED in the industry.

Introduction to RGB Common Cathode LED

RGB common cathode LED is a type of LED that has three diodes with different colors (red, green, and blue) in a single package. These diodes share a common cathode, which is the negative terminal of the LED. When a current is applied to the anode (positive terminal) of the LED, the diode emits light of the corresponding color. By controlling the current through each diode, the RGB LED can produce a wide range of colors, from pure red, green, and blue to various shades of white and other colors.
