High power infrared LED diode, as an important component in the field of optoelectronics, has been widely used in various fields such as automotive, medical, industrial, and consumer electronics. With the continuous development of technology, the application of high power infrared LED diodes has been further expanded, and its market demand has been increasing. In this article, we will introduce the industry of high power infrared LED diodes, including its definition, working principle, application fields, market trends, and development prospects.

Definition and Classification of High Power Infrared LED Diodes

High power infrared LED diode refers to a semiconductor device that emits infrared light with a power of more than 100mW. It is a kind of light-emitting diode (LED) with high luminous efficiency, long service life, and small size. According to the emission wavelength, high power infrared LED diodes can be divided into near-infrared, mid-infrared, and far-infrared three categories. The near-infrared LED diode has a wavelength of 700nm to 1000nm, the mid-infrared LED diode has a wavelength of 1000nm to 2500nm, and the far-infrared LED diode has a wavelength of 2500nm to 3000nm.

Working Principle of High Power Infrared LED Diodes

The working principle of high power infrared LED diodes is based on the principle of semiconductor p-n junction. When a forward voltage is applied to the p-n junction, electrons and holes are injected into the depletion region, and then recombine with the recombination center. During the recombination process, part of the energy is released in the form of infrared light. The energy of the emitted light is determined by the band gap of the semiconductor material. The smaller the band gap, the shorter the wavelength of the emitted light, and vice versa.
