Introduction to Far IR LED Industry

What is Far IR LED?

Far infrared (Far IR) LED stands for far infrared light-emitting diode, which is a type of semiconductor device that emits infrared light at a wavelength longer than 7.7 micrometers. Unlike visible light, far infrared light is not visible to the human eye. It is widely used in various fields, such as medical, industrial, agricultural, and consumer electronics. Far IR LED technology has been rapidly developing in recent years, and its market demand is increasing.

Working Principle of Far IR LED

The working principle of Far IR LED is based on the principle of semiconductor physics. When a forward voltage is applied to the PN junction of a semiconductor material, electrons and holes are injected into the depletion region. Due to the recombination of electrons and holes, energy is released in the form of infrared light. The wavelength of the emitted light is determined by the energy band gap of the semiconductor material.

Types of Far IR LED Materials

The most commonly used materials for Far IR LED are HgCdTe, InAsSb, and InGaAsSb. These materials have a wide energy band gap, which can emit far infrared light at a wavelength of 7.7 to 30 micrometers. HgCdTe is a typical material used for short-wavelength Far IR LED, while InAsSb and InGaAsSb are suitable for long-wavelength Far IR LED.

Applications of Far IR LED

Far IR LED technology has a wide range of applications in various fields: 1. Medical Field: Far IR LED can be used for non-invasive thermal therapy, which has a therapeutic effect on various diseases such as arthritis, muscle atrophy, and wound healing.
