How High Power Infrared LED Diodes Work

High power infrared LED diodes are made using advanced semiconductor technology. They consist of a p-n junction, where the p-type and n-type semiconductor materials are doped with impurities to create a forward-biased junction. When an electrical current is applied, electrons and holes recombine at the junction, releasing energy in the form of photons. The process of emitting infrared light involves the following steps: 1. An electrical current is applied to the diode. 2. Electrons and holes recombine at the p-n junction. 3. Energy is released in the form of photons, which are emitted as infrared light. 4. The intensity of the light output is determined by the material composition and the design of the diode.
