5mm bi-color LED is a type of light-emitting diode that emits two different colors of light. This compact and versatile lighting solution has found wide applications in various industries, including consumer electronics, automotive, and industrial automation. In this article, we will delve into the details of 5mm bi-color LED, its working principle, advantages, applications, and market trends.

Introduction to 5mm Bi-color LED

The 5mm bi-color LED is a semiconductor device that emits light when an electric current passes through it. It is designed with two separate LED chips, each emitting a different color of light. The most common bi-color combinations are red and green, blue and red, and red and yellow. These LEDs are typically mounted on a small, round, or square package with a diameter of 5mm.

Working Principle of 5mm Bi-color LED

The working principle of a 5mm bi-color LED is based on the semiconductor material's ability to emit light when an electric current is applied. The LED consists of a p-n junction, where the p-type and n-type semiconductor materials are combined. When an electric current flows through the p-n junction, electrons and holes recombine, releasing energy in the form of light. In a bi-color LED, two separate LED chips are integrated into a single package. Each chip emits light at a different wavelength, corresponding to a different color. For example, a red and green bi-color LED consists of a red LED chip and a green LED chip. When the LED is powered, both chips emit light simultaneously, creating a bi-color effect.
