Infrared LED chips have become an integral part of modern technology, serving as the backbone of numerous applications across various industries. These tiny, compact devices emit infrared light, which is invisible to the human eye but can be detected by sensors and other electronic components. This article delves into the world of infrared LED chips, exploring their technology, applications, market trends, and future prospects.

Introduction to Infrared LED Chips

Infrared LED chips are a type of semiconductor device that emits infrared light when an electric current passes through them. Unlike visible light, infrared light has a longer wavelength and is not visible to the naked eye. The main advantage of infrared LED chips is their ability to provide a compact, efficient, and cost-effective solution for various applications.

How Infrared LED Chips Work

Infrared LED chips operate based on the principle of the semiconductor junction. When an electric current is applied to the chip, electrons and holes are excited and recombine, releasing energy in the form of infrared light. The color and intensity of the emitted light depend on the composition and structure of the semiconductor material used in the chip.

Materials Used in Infrared LED Chips

The most commonly used materials for infrared LED chips are gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials are chosen for their ability to emit infrared light efficiently and have a long lifespan. The specific material used can vary depending on the desired wavelength and application of the LED chip.
