Working Principle of Infrared Emitter Tube LED

Infrared emitter tube LED is a semiconductor device that converts electrical energy into infrared light. The working principle is based on the photoelectric effect. When a forward voltage is applied to the PN junction of the diode, electrons and holes are generated due to the injection of electrons from the N-type semiconductor to the P-type semiconductor. These electrons and holes recombine at the recombination zone, releasing energy in the form of infrared light.

Types of Infrared Emitter Tube LED

According to the wavelength of the emitted infrared light, infrared emitter tube LED can be divided into three types: near-infrared, mid-infrared, and far-infrared.
