Basic Principles of Mini IR LED

Mini IR LED is a semiconductor device that emits infrared light when an electric current passes through it. It consists of a p-n junction, where electrons and holes recombine, releasing energy in the form of photons. The infrared light emitted by mini IR LED has a wavelength range of 780nm to 3000nm, which is beyond the visible spectrum of human eyes.

Mini IR LED is typically made of gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium nitride (InGaN) materials. These materials have excellent optoelectronic properties, such as high light-emitting efficiency, low forward voltage, and long lifespan. The structure of mini IR LED includes an active region, a cladding layer, and a reflector, which work together to enhance the light-emitting efficiency and directivity.
