Revolutionizing Lighting: The Power of 8mm Yellow LEDs

8mm yellow LED, also known as an 8mm yellow light-emitting diode, is a type of semiconductor device that emits yellow light when an electric current is applied. It is widely used in various applications, including indicator lights, display screens, and decorative lighting. This article will provide an in-depth introduction to the 8mm yellow LED industry, covering its history, technology, applications, market trends, and future prospects.

History of 8mm Yellow LED

The history of the 8mm yellow LED can be traced back to the early 1960s when the first LED was invented by Nick Holonyak Jr. at General Electric. However, it was not until the late 1970s that yellow LEDs were developed. Since then, the technology has evolved significantly, and the 8mm yellow LED has become a popular choice for various applications.

Technology of 8mm Yellow LED

The 8mm yellow LED is a semiconductor device that consists of a p-n junction. When an electric current is applied, electrons and holes recombine at the junction, releasing energy in the form of light. The color of the light emitted depends on the energy band gap of the semiconductor material used. In the case of the 8mm yellow LED, gallium nitride (GaN) is commonly used as the semiconductor material due to its suitable energy band gap for emitting yellow light.

The structure of an 8mm yellow LED typically includes a substrate, a p-type layer, an n-type layer, and a window layer. The substrate provides mechanical support and thermal conduction, while the p-type and n-type layers create the p-n junction. The window layer helps to enhance the extraction efficiency of the emitted light.
