How High Power IR LED Works
The operation of a high power IR LED is based on the principle of electroluminescence. When an electric current is applied to the diode, electrons and holes are separated within the semiconductor material. As these charges recombine, they release energy in the form of photons, which are then emitted as infrared light. The intensity of the emitted light is determined by the material properties, the design of the LED, and the applied current.
