8mm bi-color LEDs are a type of semiconductor light-emitting diode that emits two different colors of light. These diodes are widely used in various applications, such as indicator lights, display screens, and decorative lighting. In this article, we will explore the industry surrounding 8mm bi-color LEDs, including their history, applications, and future trends.

History of 8mm Bi-color LEDs

The development of LEDs dates back to the early 20th century. However, it was not until the 1960s that LEDs began to gain widespread attention. In the 1970s, the invention of the bi-color LED marked a significant advancement in the LED industry. The 8mm bi-color LED was introduced in the 1980s, and since then, it has become a popular choice for various applications.

How 8mm Bi-color LEDs Work

8mm bi-color LEDs are composed of two separate LED chips, each emitting a different color of light. The two chips are encapsulated in a single housing, which allows them to emit two colors simultaneously. Typically, the two colors are red and green, but they can also be blue and yellow, or any other combination of colors. The working principle of an 8mm bi-color LED is based on the semiconductor material used in the LED chip. When an electric current passes through the semiconductor material, it creates a chemical reaction that emits light. The color of the light emitted depends on the energy band gap of the semiconductor material.
