Revolutionizing Lighting Design: Unveiling the Power of RGB Common Cathode LEDs

RGB common cathode LED, also known as the three-color common cathode LED, is a widely used semiconductor light-emitting device in the field of lighting and display. It can emit red, green, and blue light through a single chip, and by adjusting the brightness of the three colors, it can display a variety of colors. This article will introduce the development history, structure, application fields, and future trends of RGB common cathode LED.

Development History of RGB Common Cathode LED

The history of LED development can be traced back to the 20th century. In the 1960s, the red, green, and blue three primary colors were first successfully realized by using different semiconductor materials. In the 1970s, the red, green, and blue three-color common cathode LED was born, which laid the foundation for the development of RGB common cathode LED. With the continuous optimization of semiconductor materials and manufacturing technology, the color performance and brightness of RGB common cathode LED have been greatly improved.

Structure of RGB Common Cathode LED

The structure of RGB common cathode LED mainly includes the following parts: chip, encapsulation, and lead wire. The chip is the core part of the LED, which emits light by semiconductor material. The encapsulation is used to protect the chip and improve the service life of the LED. The lead wire is used to connect the LED with the external circuit.

The RGB common cathode LED is composed of three chips, respectively emitting red, green, and blue light. The three chips are encapsulated in a common cathode package, and the lead wire is connected to the common cathode. When the voltage is applied to the LED, the three chips emit light, and by adjusting the brightness of the three colors, various colors can be displayed.
