LED infrarrojo, or infrared LED, has become an indispensable part of modern life. With the rapid development of technology, infrared LED technology has been widely used in various fields, such as consumer electronics, automotive, medical, and industrial applications. This article will introduce the infrared LED industry, including its development history, working principle, applications, and future prospects.

Development History of Infrared LED

The development of infrared LED technology can be traced back to the 1960s. At that time, scientists discovered that when a semiconductor material was excited by an external energy source, it could emit infrared radiation. Based on this discovery, the first infrared LED was born. In the 1970s, the technology began to be applied in consumer electronics, such as remote controls. With the continuous optimization of the technology, the performance of infrared LED has been greatly improved, and its application fields have also been expanded.

Working Principle of Infrared LED

The working principle of infrared LED is based on the photoelectric effect. When a semiconductor material is excited by an external energy source, such as a battery, electrons in the material will move from the valence band to the conduction band. As the electrons move, they collide with lattice ions and emit infrared radiation. The wavelength of the emitted infrared radiation is determined by the energy band gap of the semiconductor material.
