Introduction to High Power Infrared LED Diodes

High power Infrared LED diodes are semiconductor devices that emit infrared light when an electric current passes through them. Unlike traditional LEDs, which emit visible light, Infrared LEDs emit light in the infrared spectrum, which is not visible to the human eye. The key advantage of high power Infrared LED diodes is their ability to produce intense light at high currents, which is essential for applications that require long-range detection, thermal imaging, and precision measurement.

How High Power Infrared LED Diodes Work

The operation of high power Infrared LED diodes is based on the principles of semiconductor physics. When an electric current is applied to a PN junction, electrons and holes are excited, and as they recombine, they emit photons. In the case of Infrared LEDs, these photons fall within the infrared spectrum. The efficiency of an Infrared LED diode is determined by its material composition, design, and manufacturing process.
