Basic Principles of High Power Infrared LED

High power infrared LED is a semiconductor device that emits infrared light with high power. It is mainly composed of a p-n junction, and the p-n junction is formed by the combination of p-type and n-type semiconductor materials. When the p-n junction is forward biased, electrons and holes are injected into the depletion region, and the electrons and holes recombine in the depletion region, emitting infrared light. The power of the emitted light is determined by the forward current, the structure of the LED, and the materials used.
