Top 5 IR LED Chips for Advanced Applications

Introduction to IR LED Chips

What are IR LED Chips?

Infrared (IR) LED chips, also known as infrared light-emitting diodes, are semiconductor devices that emit infrared light when an electric current passes through them. They are widely used in various applications, including remote controls, surveillance cameras, and automotive lighting systems. These chips have become an integral part of modern technology, providing a cost-effective and efficient solution for transmitting and receiving infrared signals.

How Do IR LED Chips Work?

IR LED chips are made of semiconductor materials, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When an electric current is applied to the chip, electrons and holes are injected into the semiconductor material. These electrons and holes recombine, releasing energy in the form of infrared light. The color of the emitted light depends on the composition of the semiconductor material and the energy band gap.
