Working Principles of High Power IR Emitter
The working principle of a high power IR emitter is based on the generation of heat or light through the excitation of electrons within a semiconductor material. When an electrical current passes through the semiconductor, the electrons become excited and jump to higher energy levels. As they return to their original state, they release energy in the form of infrared radiation. The intensity of the emitted radiation depends on several factors, including the type of semiconductor material used, the temperature of the emitter, and the design of the device.
