RGB LED 5mm common cathode has become an essential component in the field of lighting and display technology. With its compact size, low power consumption, and versatile color mixing capabilities, it has found wide applications in various industries, including consumer electronics, automotive, and architectural lighting. This article aims to provide an in-depth introduction to the RGB LED 5mm common cathode, covering its basic structure, working principle, applications, and market trends.

Basic Structure of RGB LED 5mm Common Cathode

The RGB LED 5mm common cathode is a three-color LED module that emits red, green, and blue light. It consists of three LED chips, each emitting one of the three primary colors. These chips are mounted on a common cathode substrate, which is usually a glass or plastic material. The substrate is then coated with a phosphor layer that converts the LED's electroluminescence into white light. The basic structure of an RGB LED 5mm common cathode includes the following components: 1. LED chips: These are the core components of the RGB LED, emitting light of different colors. 2. Substrate: The glass or plastic material on which the LED chips are mounted. 3. Phosphor layer: The layer that converts the LED's electroluminescence into white light. 4. Anode lead: The positive lead that connects the LED to the power supply. 5. Cathode lead: The negative lead that connects the LED to the common cathode substrate.

Working Principle of RGB LED 5mm Common Cathode

The RGB LED 5mm common cathode works on the principle of electroluminescence. When an electric current passes through the LED chip, it excites the electrons in the semiconductor material, causing them to recombine with electron holes. This recombination process releases energy in the form of light. In the case of RGB LED 5mm common cathode, the three LED chips emit red, green, and blue light, respectively. By controlling the intensity of the current flowing through each LED chip, the color of the emitted light can be adjusted. When red, green, and blue light are combined in different proportions, a wide range of colors can be produced. The working principle of RGB LED 5mm common cathode can be summarized as follows: 1. An electric current passes through the LED chips. 2. Electrons and electron holes recombine in the semiconductor material, emitting light. 3. The intensity of the current is controlled to adjust the color of the emitted light. 4. Red, green, and blue light are combined in different proportions to produce various colors.
