Innovative Advancements in Infrared LED Emitter Technology: A Game-Changer for Future Applications

Infrared LED emitter, also known as infrared LED, is a semiconductor light-emitting device that emits infrared light. It is widely used in various fields such as remote control, security monitoring, medical equipment, and industrial automation. This article will introduce the industry of infrared LED emitters, including their working principle, types, applications, market status, and future development trends.

Working Principle of Infrared LED Emitter

The infrared LED emitter is a semiconductor device that uses the principle of semiconductor electroluminescence. When a forward voltage is applied to the PN junction of the semiconductor material, the electrons and holes in the semiconductor material are recombined, releasing energy in the form of light. Due to the difference in energy levels between the valence band and the conduction band of the semiconductor material, the emitted light is in the infrared spectrum.

The main semiconductor materials used in infrared LED emitters include gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide phosphide (InGaAsP). These materials have good infrared emission characteristics and can emit infrared light with different wavelengths according to the material composition and structure.

Types of Infrared LED Emitter

1. According to the wavelength: Infrared LED emitters can be divided into near-infrared, mid-infrared, and far-infrared according to the wavelength of the emitted light. Near-infrared has a wavelength of 0.76-3.0μm, mid-infrared has a wavelength of 3.0-30μm, and far-infrared has a wavelength of 30-1000μm.

2. According to the light-emitting mode: Infrared LED emitters can be divided into surface emitting and edge emitting according to the light-emitting mode. Surface emitting infrared LED emitters have a larger emitting surface, while edge emitting infrared LED emitters have a higher light intensity and a smaller emitting area.

3. According to the application field: Infrared LED emitters can be divided into general-purpose infrared LED emitters and special-purpose infrared LED emitters according to the application field. General-purpose infrared LED emitters are widely used in remote control, security monitoring, and other fields, while special-purpose infrared LED emitters are used in specific fields such as medical equipment, industrial automation, and communication.
