Introduction to Infrared LED Light Technology

What is Infrared LED Light?

Infrared LED light, short for Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared radiation when an electric current is applied to it. Unlike visible light, infrared light is not visible to the naked eye, but it is widely used in various applications due to its unique properties. The wavelength of infrared light ranges from 700 nanometers (nm) to 1 millimeter (mm), making it an essential component in many modern technologies.

How Does Infrared LED Light Work?

The working principle of an infrared LED is similar to that of a standard LED. It consists of a semiconductor material, typically made of gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium nitride (InGaN). When an electric current is applied to the diode, electrons and holes are excited and recombine within the semiconductor material. This recombination process releases energy in the form of infrared radiation. The structure of an infrared LED is designed to maximize the emission of infrared light. The semiconductor material is sandwiched between two metal contacts, and the emitted light is directed through a lens or a reflector to enhance its intensity and directivity. The efficiency of an infrared LED is determined by the quality of the semiconductor material, the design of the diode, and the cooling system.
