5mm bi-color LED, also known as a dual-color LED, is a type of light-emitting diode that emits two different colors of light. It is widely used in various applications, such as indicator lights, display screens, and decorative lighting. In this article, we will delve into the industry of 5mm bi-color LED, exploring its history, technology, applications, and market trends.

History of 5mm Bi-color LED

The invention of the LED dates back to the early 20th century. However, it was not until the 1960s that the first practical LED was developed. Since then, LED technology has evolved rapidly, and the 5mm bi-color LED has become a popular choice in the market. In the 1970s, bi-color LEDs were introduced, which could emit two different colors of light. Over the years, the technology has continued to improve, and today, 5mm bi-color LEDs are widely used in various industries.

Technology of 5mm Bi-color LED

The 5mm bi-color LED is a semiconductor device that emits light when an electric current passes through it. It consists of a chip, a lead frame, and a package. The chip is the core component of the LED, which emits light. The lead frame is used to connect the chip to the external circuit, and the package is used to protect the chip and improve its heat dissipation. The 5mm bi-color LED can emit two different colors of light, such as red and green, red and blue, or red and yellow. This is achieved by using two different types of semiconductor materials in the chip. For example, a red and green bi-color LED uses a red phosphor layer on a green LED chip. When the LED is powered on, the green light is emitted from the chip, and the red light is emitted from the phosphor layer.
