In this article, we will delve into the industry of 3mm bi-color LED, exploring its features, applications, and market trends.

Introduction to 3mm Bi-color LED

The 3mm bi-color LED is a semiconductor device that emits light when an electric current passes through it. It consists of two separate LED chips, each emitting light in a different color. In most cases, one chip emits red light, while the other emits green light. By controlling the current flowing through each chip, the intensity of each color can be adjusted, allowing for a wide range of color combinations and brightness levels. The 3mm bi-color LED is designed with a transparent or diffused lens to focus or scatter the light, providing a clear or soft illumination effect. It is typically mounted on a printed circuit board (PCB) or a flexible circuit, making it easy to integrate into various electronic devices.
