Introduction to High Power Infrared Light Emitting Diode

A high power infrared light emitting diode (HP-IRLED) is a semiconductor device that emits infrared radiation when an electric current is applied. It is a type of light-emitting diode (LED) that operates at a wavelength between 700 nm and 3000 nm, which is beyond the visible spectrum. HP-IRLEDs are widely used in various applications due to their high brightness, long lifespan, and energy efficiency. The structure of an HP-IRLED consists of a p-n junction, where electrons and holes recombine to emit photons. The p-n junction is formed by diffusing a p-type semiconductor material into an n-type semiconductor material. When an electric current is applied, electrons and holes are injected into the depletion region, where they recombine and emit infrared radiation.
