Introduction to High Power Infrared LEDs

High power infrared LEDs are semiconductor devices that emit light in the infrared spectrum when an electric current is applied. Unlike visible light, infrared radiation is not visible to the human eye but can be detected by specialized sensors. These LEDs are made using a combination of materials such as gallium arsenide (GaAs), gallium nitride (GaN), and indium gallium nitride (InGaN), which are chosen for their ability to emit infrared light efficiently.

Working Principle of High Power Infrared LEDs

The working principle of high power infrared LEDs is based on the quantum mechanical phenomenon of electroluminescence. When an electric current is applied to the semiconductor material, electrons and holes are excited and recombine, releasing energy in the form of photons. The energy of these photons determines the wavelength of the emitted light, which falls within the infrared spectrum for high power infrared LEDs.
