Working Principles of Diode IR

The working principle of diode IR technology involves the use of a semiconductor diode, typically made of materials like gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). When an electrical current is applied to the diode, it emits infrared light due to the generation of electron-hole pairs within the semiconductor material. These pairs recombine, releasing energy in the form of infrared radiation.

The intensity of the emitted light is directly proportional to the current passing through the diode. By controlling the current, the intensity and wavelength of the emitted infrared light can be adjusted to suit different applications.
