RGB LED 5mm common cathode has become an essential component in the field of lighting and display technology. This compact and versatile LED is widely used in various applications, such as home lighting, automotive lighting, and decorative lighting. In this article, we will delve into the details of RGB LED 5mm common cathode, including its structure, working principle, advantages, and applications.

Structure of RGB LED 5mm Common Cathode

RGB LED 5mm common cathode is a three-color LED that emits red, green, and blue light. It consists of three LED chips, each with a different color, mounted on a common cathode substrate. The common cathode substrate is usually made of ceramic or plastic, and it serves as the electrical connection for the three LED chips. The three LED chips are encapsulated in a transparent or colored lens, which helps to focus the light and protect the LED chips from external damage.

Working Principle of RGB LED 5mm Common Cathode

The working principle of RGB LED 5mm common cathode is based on the phenomenon of color mixing. When red, green, and blue light are combined, they can produce a wide range of colors. The intensity of each color can be controlled by adjusting the current flowing through the corresponding LED chip. By adjusting the current of each color, the RGB LED can display different colors and brightness levels. The RGB LED 5mm common cathode works as follows: 1. The input voltage is applied to the common cathode substrate. 2. The current flows through the common cathode substrate and reaches the three LED chips. 3. The current passing through each LED chip generates light of a specific color. 4. The light emitted by the three LED chips is mixed to produce the desired color. 5. The brightness of each color can be adjusted by controlling the current.
