The main difference between RGB LEDs and normal LEDs lies in their light-emitting principles and color expression capabilities.

 

1. Luminous principle:

 

• Normal LED: Normal LEDs are usually light-emitting diodes of a single color, such as red, green or blue. They emit light through the flow of electric current in semiconductor materials, and the light emitted is a fixed single color.

• RGB LED: RGB LED is a type of LED that can emit three basic colors: red, green, and blue. They are usually composed of three separate LED chips (red, green, and blue) combined together, and by adjusting the brightness of each color, a variety of colors can be mixed.

 

2. Color performance:

 

• Normal LED: can only emit one color and cannot be changed.

• RGB LED: It can produce almost infinite color variations by adjusting the brightness combination of red, green and blue. This makes RGB LED very popular in applications that require multiple colors, such as color lighting, display screens and decorative lights.

 

3. Control method:

 

• Normal LED: Usually only requires simple power control.

• RGB LED: Requires more complex control circuitry, typically using PWM (Pulse Width Modulation) technology to adjust the brightness of each color to achieve color mixing and changing.

 

Overall, the flexibility and versatility of RGB LEDs have led to their widespread use in modern lighting and display technologies, while regular LEDs are suitable for simple applications that require a single color.
