Introduction to Infrared Power LED Industry

Infrared Power LED: What is It?

The infrared power LED, also known as the infrared LED, is a type of light-emitting diode that emits infrared light. Unlike visible light, infrared light is not visible to the human eye. It is widely used in various applications, such as remote controls, communication systems, and security systems. The infrared power LED industry has been growing rapidly in recent years, driven by the increasing demand for infrared technology in various fields.

How Does an Infrared Power LED Work?

An infrared power LED works on the principle of electroluminescence. When an electric current passes through the semiconductor material, it emits infrared light. The semiconductor material used in infrared power LEDs is typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to emit infrared light efficiently. The structure of an infrared power LED typically consists of a p-n junction, where the p-type and n-type semiconductor materials are joined together. When an electric current is applied, electrons and holes recombine at the junction, releasing energy in the form of infrared light. The wavelength of the emitted light depends on the composition and structure of the semiconductor material.
