High power IR emitter, as the name suggests, refers to a device that emits infrared radiation with high power output. In recent years, with the rapid development of infrared technology, high power IR emitters have been widely used in various fields such as industrial automation, medical equipment, security monitoring, and consumer electronics. This article will introduce the industry of high power IR emitter, including its working principle, types, applications, and market trends.

Working Principle of High Power IR Emitter

High power IR emitters work based on the principle of semiconductor physics. When a forward voltage is applied to the semiconductor material, electrons and holes are excited and recombine, releasing energy in the form of infrared radiation. The power output of the IR emitter is determined by the size of the semiconductor material, the current passing through the material, and the temperature of the device.

Types of High Power IR Emitter

There are mainly two types of high power IR emitters: semiconductor diode IR emitters and quantum dot IR emitters. 1. Semiconductor diode IR emitters: This type of emitter is the most common and widely used in the market. It is made of gallium arsenide (GaAs), gallium phosphide (GaP), or other semiconductor materials. The emission wavelength of the diode IR emitter can be tuned by adjusting the composition of the semiconductor material. 2. Quantum dot IR emitters: Quantum dot IR emitters are a new type of high power IR emitter with excellent performance. Quantum dots are semiconductor nanoparticles with a size of several nanometers. By controlling the size and composition of the quantum dots, the emission wavelength of the quantum dot IR emitter can be tuned to the desired range.
