Introduction to High Power Infrared Light Emitting Diodes

High power infrared light emitting diodes are semiconductor devices that emit infrared light when an electric current is applied. Unlike conventional light emitting diodes (LEDs), which emit visible light, HP-IRLEDs operate in the infrared spectrum, which is beyond the range of human vision. The key characteristics of HP-IRLEDs include high brightness, low power consumption, and a long lifespan.

How HP-IRLEDs Work

The operation of HP-IRLEDs is based on the principle of electroluminescence, which occurs when an electric current passes through a semiconductor material. This process excites the electrons within the material, causing them to recombine with electron holes, releasing energy in the form of photons. In the case of HP-IRLEDs, these photons are in the infrared region of the electromagnetic spectrum. The semiconductor material used in HP-IRLEDs is typically a compound semiconductor, such as gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). These materials are chosen for their ability to emit infrared light at high intensities and their thermal stability. The structure of an HP-IRLED typically includes a p-n junction, which is responsible for the electroluminescent process.
