Introducing the Infrared LED: A Revolution in Lighting Technology

Introduction to Infrared LEDs

In recent years, the technology industry has witnessed a remarkable surge in the development and adoption of infrared LEDs (IR LEDs). These devices have become integral to various applications, ranging from consumer electronics to industrial automation. An IR LED, also known as an infrared light-emitting diode, is a semiconductor device that emits infrared light when an electric current passes through it. This article aims to provide a comprehensive overview of the IR LED industry, highlighting its key features, applications, market trends, and future prospects.

How IR LEDs Work

An IR LED operates based on the principle of the p-n junction. When an electric current is applied to the diode, electrons and holes are injected into the depletion region, where they recombine and release energy in the form of photons. The emitted light has a wavelength ranging from 700 nm to 3000 nm, making it invisible to the human eye. The infrared light produced by IR LEDs is widely used for various purposes, including remote control, communication, and sensing.
