Infrared IR LED: Revolutionizing Remote Control Technology and Beyond

Infrared IR LED, or infrared emitting diode, is a type of light-emitting diode that emits infrared radiation. It is widely used in various fields, such as remote control, surveillance, communication, and medical equipment. This article will introduce the industry of infrared IR LED, including its working principle, types, applications, and market trends.

Working Principle of Infrared IR LED

The working principle of infrared IR LED is based on the PN junction of a semiconductor material. When the forward voltage is applied to the PN junction, electrons and holes are generated due to the injection of electrons from the N-type semiconductor to the P-type semiconductor. When these electrons and holes recombine, they emit photons with energy. The energy of the photons is determined by the band gap of the semiconductor material. In the case of infrared IR LED, the semiconductor material with a band gap of 0.9-1.7 eV is usually used, which emits infrared radiation with a wavelength of 940-1700 nm.

Types of Infrared IR LED

According to the wavelength, infrared IR LED can be divided into three types: near-infrared, mid-infrared, and far-infrared. The near-infrared infrared IR LED has a wavelength of 940-1400 nm, and is often used in remote control and communication applications. The mid-infrared infrared IR LED has a wavelength of 1400-1600 nm, and is mainly used in thermal imaging and gas detection. The far-infrared infrared IR LED has a wavelength of 1600-1700 nm, and is mainly used in medical equipment and industrial applications.
