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 invisible 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 LED was first introduced in the 1960s by Nick Holonyak, Jr., at General Electric. However, it wasn't until the 1970s that IR LEDs were developed, thanks to the advancements in semiconductor technology. The first IR LEDs were primarily used in remote controls, and since then, their applications have expanded exponentially.

How IR LEDs Work

IR LEDs work on the principle of the semiconductor junction. When an electric current is applied to the junction, electrons and holes recombine, releasing energy in the form of photons. In the case of IR LEDs, these photons fall within the infrared spectrum, making them invisible to the naked eye. The color of the emitted light depends on the material used in the LED's semiconductor layer.

Types of IR LEDs

There are several types of IR LEDs, each with its own unique characteristics and applications. The most common types include:

• AlInGaP IR LEDs: These LEDs are known for their high brightness and are commonly used in applications requiring long-range communication.
