With the rapid development of modern technology, the application of high power IR emitter has been widely extended to fields such as industrial automation, medical treatment, security monitoring, and consumer electronics. This article will introduce the concept, development, and application of high power IR emitter in detail, providing readers with a comprehensive understanding of this cutting-edge technology.

Concept and Classification of High Power IR Emitter

High power IR emitter refers to a device that can emit infrared radiation with high power output. According to the working principle, it can be divided into semiconductor infrared emitter and thermal infrared emitter. Semiconductor infrared emitter uses the semiconductor material to generate infrared radiation, and its power output can be adjusted by controlling the current. Thermal infrared emitter, on the other hand, converts electric energy into heat energy through the thermal effect, and then emits infrared radiation. According to the spectral range, high power IR emitter can be divided into near-infrared, mid-infrared, and far-infrared emitters.

Development of High Power IR Emitter

The development of high power IR emitter can be traced back to the 20th century. At that time, the main types of infrared emitters were based on thermal radiation, such as filament lamps and quartz lamps. With the continuous development of semiconductor technology, semiconductor infrared emitters have gradually replaced thermal infrared emitters due to their high efficiency, small size, and low power consumption. In the 1980s, the development of gallium arsenide (GaAs) and gallium nitride (GaN) semiconductor materials has promoted the rapid development of high power IR emitter technology. At present, high power IR emitter technology has entered a mature stage, and its application fields are constantly expanding.
