Infrared LED Chip: A Key Component in Modern Technology

In the rapidly evolving world of technology, the infrared LED chip has emerged as a crucial component in various applications. As a semiconductor device, the infrared LED chip emits infrared light, which is invisible to the human eye. This technology has found its way into numerous industries, from consumer electronics to automotive and industrial sectors. This article aims to provide an in-depth introduction to the infrared LED chip, its working principle, applications, and the future trends in this field.

Working Principle of Infrared LED Chip

The infrared LED chip operates based on the principle of electroluminescence. When an electric current passes through the semiconductor material, it generates heat, which excites the electrons within the material. As the electrons return to their original state, they release energy in the form of photons. In the case of an infrared LED chip, these photons are in the infrared spectrum, which is beyond the visible range of human eyes. The semiconductor material used in infrared LED chips is typically a compound semiconductor, such as gallium arsenide (GaAs) or gallium nitride (GaN). These materials have a direct bandgap, which allows them to efficiently emit infrared light when excited by an electric current. The structure of an infrared LED chip typically consists of a p-n junction, where the p-type and n-type regions are doped with impurities to create a potential barrier. This barrier controls the flow of electrons and the emission of infrared light.
