With the rapid development of the semiconductor industry and the increasing demand for high-quality lighting products, the 5mm bi-color LED has become a hot topic in the industry. As a miniature light-emitting device, 5mm bi-color LED has the advantages of small size, high brightness, low power consumption, and wide application range, and has been widely used in various fields such as household appliances, automotive lighting, and outdoor lighting. In this article, we will introduce the 5mm bi-color LED in detail, including its working principle, characteristics, application fields, and future development trends.

Introduction to 5mm Bi-color LED

The 5mm bi-color LED is a type of light-emitting diode that emits two different colors of light, usually red and green, at the same time. The core of the 5mm bi-color LED is a single crystal chip, which is encapsulated in a 5mm plastic package. Through the control of the current, the 5mm bi-color LED can achieve the effect of red and green light mixing, and emit a variety of color combinations.

Working Principle of 5mm Bi-color LED

The working principle of the 5mm bi-color LED is based on the semiconductor physics. When the current passes through the semiconductor chip, the electrons and holes in the semiconductor material recombine, and the energy released during the recombination is emitted as light. In the case of a 5mm bi-color LED, there are two types of semiconductor materials in the chip, one emitting red light and the other emitting green light. By adjusting the current, the proportion of red and green light can be controlled, thus achieving the effect of bi-color light.
