Introduction

Infrared LED Chip: A Brief Overview

Infrared LED chips, also known as infrared emitting diodes, are a type of semiconductor devices that emit infrared light when an electric current passes through them. They are widely used in various applications, including consumer electronics, automotive, medical, and industrial fields. As the demand for infrared technology continues to grow, the market for infrared LED chips is expected to expand significantly in the coming years.

How Infrared LED Chips Work

Infrared LED chips are based on the principle of the PN junction. When an electric current is applied to the PN junction, electrons and holes recombine, releasing energy in the form of infrared light. The wavelength of the emitted light depends on the material used in the chip, with typical wavelengths ranging from 780nm to 950nm. The key components of an infrared LED chip include the epitaxial layer, the substrate, and the metal contact. The epitaxial layer is the active region where the light is emitted, and it is grown on a substrate material, usually silicon or gallium arsenide. The metal contact is used to apply the electric current to the chip.
