Basic Concept of High Power IR Emitter

High power IR emitter is a kind of infrared radiation device that can emit high-power infrared beams. It is mainly used for long-distance transmission of infrared signals, thermal imaging, and other applications. The basic principle of high-power IR emitter is based on the photoelectric effect. By converting electrical energy into light energy, it can emit a strong infrared beam.

Working Principle of High Power IR Emitter

The working principle of high-power IR emitter is based on the photoelectric effect. The process can be divided into the following steps: 1. Excitation: When an external electric field is applied to the semiconductor material, electrons and holes are excited, and the semiconductor material enters the conduction band. 2. Emission: The excited electrons recombine with holes, releasing energy in the form of photons. The photons have a certain wavelength, which falls within the infrared range. 3. Amplification: The emitted infrared photons are then amplified through optical amplification, and finally output as a high-power infrared beam.
