3mm bi-color LED is a type of LED that emits two different colors simultaneously. It is widely used in various applications, such as indicator lights, decorative lighting, and automotive lighting. In this article, we will delve into the industry of 3mm bi-color LED, exploring its history, technology, applications, and future trends.

History of 3mm Bi-color LED

The development of LED technology dates back to the early 20th century. However, it was not until the 1960s that the first practical LED was invented by Nick Holonyak Jr. at General Electric. Since then, LED technology has been rapidly evolving, and the 3mm bi-color LED is one of the latest advancements in this field. In the 1970s, the first bi-color LED was developed, which could emit two different colors simultaneously. However, it was not until the 1990s that the 3mm bi-color LED became widely available. This was due to the advancements in LED packaging technology, which allowed for the miniaturization of the LED and the integration of multiple dies into a single package.

Technology of 3mm Bi-color LED

The 3mm bi-color LED is a compact, high-efficiency light source that can emit two different colors. It typically consists of two separate dies, each emitting a different color. The most common colors are red and green, but other color combinations are also available. The two dies are mounted on a single substrate, which is then encapsulated in a clear or colored lens. The lens helps to focus the light and protect the LED from environmental factors. The electrical connections are made through a pair of leads that are soldered to the substrate. The 3mm bi-color LED operates on a low voltage, typically between 2.0V and 3.3V. This makes it suitable for a wide range of applications, including battery-powered devices. The LED has a high brightness and a long lifespan, making it an ideal choice for indicator lights and decorative lighting.
