Innovative Infrared IR LED Technology: Advancements and Applications Unveiled

Introducing Infrared IR LED: A Revolutionary Technology in the Lighting Industry

Infrared IR LED: An Overview

Infrared IR LED, also known as infrared light-emitting diode, is a type of semiconductor device that emits infrared light. It has gained significant attention in various industries due to its unique properties and applications. This article aims to provide an in-depth introduction to infrared IR LED, covering its working principle, advantages, applications, and future trends.

Working Principle of Infrared IR LED

Infrared IR LED operates on the principle of semiconductor physics. When an electric current passes through the diode, electrons and holes recombine, releasing energy in the form of infrared light. The emitted light has a wavelength range of 700 to 1500 nanometers, which falls between visible light and microwave frequencies.

The key components of an infrared IR LED include the semiconductor material, a p-n junction, and an encapsulant. The semiconductor material, typically made of gallium arsenide (GaAs), indium gallium arsenide (InGaAs), or aluminum gallium arsenide (AlGaAs), determines the emission wavelength of the LED. The p-n junction is responsible for generating the electric current, while the encapsulant protects the diode and enhances its performance.
