Buy IR LED: A Comprehensive Industry Overview

Introduction to IR LEDs

Buy IR LED, or infrared light-emitting diodes, has become a crucial component in various industries due to their unique properties and applications. IR LEDs emit light in the infrared spectrum, which is not visible to the human eye. This makes them ideal for a wide range of applications, from remote controls to medical imaging. In this article, we will delve into the world of IR LEDs, exploring their history, technology, applications, and market trends.

History of IR LEDs

The concept of the light-emitting diode (LED) was first proposed by Oleg Losev in 1927. However, it wasn't until the 1960s that the first practical IR LED was developed by Nick Holonyak Jr. at General Electric. Since then, the technology has evolved significantly, with improvements in efficiency, brightness, and lifespan. Today, IR LEDs are a mature technology with a wide range of applications across various industries.

How IR LEDs Work

IR LEDs work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in IR LEDs is typically a compound of gallium, arsenide, and phosphide (GaAsP). When an electric current is applied, electrons and holes recombine in the semiconductor, releasing energy in the form of infrared light.

IR LEDs are characterized by their wavelength, which determines the color of the light they emit. The most common wavelengths for IR LEDs range from 780 nm to 3000 nm, with different applications requiring specific wavelengths.
