Introduction to High Power Infrared LED Diodes

High power infrared LED diodes are semiconductor devices that emit infrared light when an electric current passes through them. Unlike traditional light-emitting diodes (LEDs), which emit visible light, infrared LEDs produce light in the infrared spectrum, which is beyond the range of human vision. These diodes are made of materials such as gallium arsenide (GaAs), gallium nitride (GaN), and indium gallium arsenide phosphide (InGaAsP), which have high thermal conductivity and efficient light emission properties.

Working Principle

The working principle of a high power infrared LED diode is based on the quantum mechanical effect known as the electroluminescence. When an electric current is applied to the diode, electrons and holes recombine at the PN junction, releasing energy in the form of photons. The energy of these photons corresponds to the infrared region of the electromagnetic spectrum, which has wavelengths between 700 nanometers and 1 millimeter.
