Basic Concepts of Infrared Emitter LED

Infrared emitter LED, also known as infrared diode, is a semiconductor device that emits infrared light when an electric current passes through it. It is mainly composed of a p-n junction, and its core material is usually gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs). The emitted infrared light has a wavelength range of 0.75 to 3.0 micrometers, which is invisible to the human eye.

Development History of Infrared Emitter LED

The development of infrared emitter LED can be traced back to the 1960s. At that time, scientists discovered that when a forward bias was applied to a semiconductor material, it could emit light. In the 1970s, with the continuous improvement of semiconductor technology, infrared emitter LED began to be used in practical applications.
