Introduction to High Power Infrared LED Diodes

High power infrared LED diodes are semiconductor devices that emit infrared light at high intensities. Unlike traditional light-emitting diodes (LEDs), which emit visible light, infrared LEDs operate in the invisible infrared spectrum. The power of these diodes can range from a few watts to tens of watts, making them suitable for high-intensity applications.

The working principle of a high power infrared LED diode is based on the quantum mechanical phenomenon known as electroluminescence. When an electric current is applied to the diode, electrons and holes recombine in the active region, releasing energy in the form of photons. The wavelength of these photons falls within the infrared spectrum, which is not visible to the human eye.
