Introducing the 3mm bi-color LED, a compact and versatile lighting solution that has gained significant popularity in various industries. This article aims to provide a comprehensive introduction to the 3mm bi-color LED, covering its features, applications, advantages, and market trends.

What is a 3mm Bi-color LED?

A 3mm bi-color LED is a type of light-emitting diode (LED) that emits light in two different colors. These LEDs are typically mounted on a small, round package with a diameter of 3mm. The two colors can be chosen from a wide range of options, such as red and green, blue and red, or white and red, depending on the application requirements.

How Does a 3mm Bi-color LED Work?

The working principle of a 3mm bi-color LED is similar to that of a single-color LED. It consists of a semiconductor material that emits light when an electric current passes through it. In the case of a bi-color LED, there are two separate semiconductor layers, each emitting a different color of light. By controlling the current flow through each layer, the LED can produce a combination of the two colors.
