RGB LED

General Description:

An RGB LED is a type of light-emitting diode that can emit light in three primary colors: red (R), green (G), and blue (B). By adjusting the intensity of each color component, a wide range of colors can be produced. These LEDs are commonly used in various applications where colorful lighting effects are desired.

Working Principle:

The working principle of an RGB LED involves three separate semiconductor chips within a single package, each emitting red, green, or blue light when current passes through. By varying the intensity of each color using pulse-width modulation (PWM), the LED can create a wide spectrum of colors by mixing these primary colors. For instance, activating only the red light source results in a red glow, while combining red and green produces yellow because these colors mix to form yellow light. This process of mixing different intensities of red, green, and blue light sources enables RGB LEDs to generate a wide range of colors, demonstrating the fundamental principle of color mixing in light.
