Introduction

Infrared Emitter LED: A Brief Overview

The infrared emitter LED, or infrared emitting diode, is a type of semiconductor device that emits infrared light when an electric current is applied to it. This technology has become increasingly popular in various industries due to its numerous applications, including remote controls, security systems, and medical devices. In this article, we will delve into the world of infrared emitter LEDs, exploring their working principles, advantages, applications, and future trends.

Working Principles

The infrared emitter LED operates on the principle of electroluminescence, which is the process of emitting light from a material when an electric current is applied. In the case of infrared emitter LEDs, the material used is a semiconductor, typically gallium arsenide (GaAs) or gallium nitride (GaN). When an electric current passes through the semiconductor material, electrons and holes recombine, releasing energy in the form of photons. These photons have a longer wavelength than visible light, which makes them infrared. The infrared emitter LED is typically composed of a p-n junction, where the p-type and n-type semiconductor materials are joined together. The p-type material has an excess of positively charged holes, while the n-type material has an excess of negatively charged electrons. When an electric current is applied, the electrons from the n-type material move towards the p-type material, recombining with the holes. This process generates infrared light.
