2. Working Principle of High Power Infrared Transmitter Diode

The working principle of high power infrared transmitter diode is based on the photoelectric effect of semiconductor materials. When the forward bias voltage is applied to the diode, the electrons in the valence band are excited to the conduction band, and the holes in the valence band are left behind. As the electrons and holes move to the junction, they recombine and emit infrared light. The intensity of the emitted light is proportional to the current passing through the diode.
