Infrared IR LED, also known as infrared emitting diode, is a type of semiconductor device that emits infrared light when an electric current passes through it. This technology has been widely used in various fields such as consumer electronics, automotive, medical, and industrial applications. In this article, we will introduce the industry of infrared IR LED, covering its history, technology, applications, market trends, and future development.

History of Infrared IR LED

The history of infrared IR LED dates back to the early 20th century. In 1908, Henry Joseph Round, an English physicist, discovered that when a direct current was applied to a crystal, it emitted infrared light. This discovery laid the foundation for the development of infrared technology. In the 1950s, infrared IR LED was first developed and used in remote controls. Since then, infrared IR LED technology has been continuously optimized and innovated, and its applications have been expanding to various fields.

Technology of Infrared IR LED

Infrared IR LED is a semiconductor device that emits infrared light. The main material used in the production of infrared IR LED is gallium arsenide (GaAs) or gallium phosphide (GaP). When an electric current passes through the semiconductor material, the electrons and holes recombine, releasing energy in the form of infrared light. The wavelength of the emitted infrared light can be adjusted by changing the composition of the semiconductor material. The key parameters of an infrared IR LED include forward voltage, forward current, peak wavelength, and emission angle. Forward voltage refers to the voltage required to make the LED work; forward current refers to the current required to make the LED emit light; peak wavelength refers to the central wavelength of the emitted light; and emission angle refers to the angle at which the light is emitted.
