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 infrared technology, high power IR emitters have become an indispensable part of various fields, such as military, medical, industrial, and consumer electronics. This article will introduce the industry of high power IR emitters, including their working principles, types, applications, and market trends.

Working Principles of High Power IR Emitters

High power IR emitters work based on the photoelectric effect. When a semiconductor material is exposed to light, it can generate an electric current. By using this principle, high power IR emitters can convert electrical energy into infrared radiation. The process can be summarized as follows: 1.

Electric current passes through the semiconductor material, causing electrons to move and collide with atoms in the material.

2.

When electrons collide with atoms, they can transfer energy to the atoms, causing them to vibrate and emit infrared radiation.

3.

The emitted infrared radiation is then amplified and directed by the optical system of the emitter.
