3mm bi-color LED red green has emerged as a popular choice in the lighting industry due to its versatility and efficiency. This article delves into the details of these compact, dual-color LEDs, exploring their applications, technology, and the market trends surrounding them.

Introduction to 3mm Bi-color LED Red Green

The 3mm bi-color LED red green is a type of light-emitting diode that emits light in two distinct colors: red and green. These LEDs are compact, measuring just 3mm in diameter, making them ideal for a wide range of applications where space is limited. The ability to emit two colors from a single package adds to their appeal, as it allows for more creative lighting designs and functions.

How Do 3mm Bi-color LED Red Green Work?

The 3mm bi-color LED red green operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. Each color is achieved by using different semiconductor materials. The red color is typically produced using aluminum gallium indium phosphide (AlGaInP) or aluminum gallium arsenide (AlGaAs), while the green color is produced using gallium nitride (GaN) or zinc sulfide (ZnS). The dual-color LED is designed with two separate LED dies, each encapsulated in a single package. The dies are often mounted on a common substrate, allowing for efficient heat dissipation and electrical connection. By controlling the current flowing through each die, the intensity of each color can be adjusted independently, providing a wide range of color combinations and brightness levels.
