Far IR LED: An Overview

Far infrared (far IR) LED technology has emerged as a significant innovation in the field of infrared lighting and heating. These LEDs emit light in the far infrared spectrum, which ranges from 5 to 1000 micrometers. Unlike traditional infrared sources, far IR LEDs offer several advantages such as high efficiency, low power consumption, and compact size. This article aims to provide an in-depth introduction to far IR LED technology, its applications, and the industry landscape.

Background

The concept of infrared radiation has been known for centuries, with early experiments dating back to the 17th century. However, it was not until the late 19th century that the term "infrared" was coined by Sir William Herschel, who discovered that there was a heat-emitting radiation beyond the red end of the visible spectrum. Over the years, infrared technology has evolved, and today, far IR LEDs are playing a crucial role in various industries.

How Far IR LEDs Work

Far IR LEDs work by emitting photons in the far infrared spectrum. These photons have longer wavelengths than visible light, which makes them invisible to the human eye. The working principle of far IR LEDs is based on the quantum mechanical properties of semiconductors. When a semiconductor material, such as gallium arsenide (GaAs), is subjected to an electric current, electrons are excited and move to higher energy levels. As these electrons return to their original energy levels, they release energy in the form of photons. The specific wavelength of the emitted photons depends on the energy bandgap of the semiconductor material.

Advantages of Far IR LEDs

There are several advantages of far IR LEDs that make them a preferred choice in various applications: 1.
