High power IR emitter, as the name suggests, refers to a device that emits infrared radiation with high power. In recent years, with the rapid development of the Internet of Things, smart home, and other fields, high power IR emitter has become an indispensable part of the industry. This article will introduce the definition, classification, working principle, application fields, and future development trends of high power IR emitter.

Definition and Classification of High Power IR Emitter

High power IR emitter is a device that converts electrical energy into infrared radiation with high power. It is widely used in various fields such as industrial automation, security monitoring, medical equipment, and consumer electronics. According to the working principle, high power IR emitter can be divided into several types, such as semiconductor IR emitter, gas discharge IR emitter, and thermal IR emitter.

Working Principle of High Power IR Emitter

The working principle of high power IR emitter is based on the photoelectric effect and thermal effect. Semiconductor IR emitter is the most commonly used type of high power IR emitter. It is made of semiconductor materials, such as gallium arsenide (GaAs) and indium phosphide (InP). When the semiconductor material is excited by an external electric field, electrons and holes are generated, and the recombination of electrons and holes will emit infrared radiation.

Gas discharge IR emitter is another type of high power IR emitter. It uses a gas discharge tube as the radiation source, and the discharge process generates high-intensity infrared radiation. Thermal IR emitter is based on the thermal effect, which converts electrical energy into heat energy, and then emits infrared radiation. The intensity of the emitted infrared radiation is related to the temperature of the heat source.
