Introduction to Bi-color LED 3mm

Bi-color LED 3mm refers to a type of light-emitting diode (LED) that emits light in two different colors, typically red and green, from a single package with a diameter of 3mm. These LEDs are designed to provide a dual-color output while maintaining a compact size, making them highly sought after in numerous lighting applications.

How Bi-color LED 3mm Works

The bi-color LED 3mm operates on the principle of color mixing. It contains two separate diodes within a single housing, each emitting light at a different wavelength. The red and green diodes are electrically isolated but share a common cathode or anode, depending on the design. By controlling the current flowing through each diode, the intensity of each color can be adjusted, allowing for a wide range of color combinations.
