Infrared LED emitter, also known as infrared light-emitting diode, is a type of electronic device that emits infrared light. With the rapid development of technology, infrared LED emitters have been widely used in various fields, such as security, communication, remote control, and medical treatment. This article will introduce the industry of infrared LED emitters, including their working principle, application fields, market trends, and future development prospects.

Working Principle of Infrared LED Emitter

Infrared LED emitters are based on the principle of semiconductor physics. When a forward voltage is applied to the semiconductor material, electrons and holes will be generated, and the recombination of electrons and holes will emit photons. The wavelength of the emitted light is determined by the energy gap of the semiconductor material. Infrared LED emitters usually use gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) as the semiconductor material, which can emit infrared light with a wavelength of 780nm to 3um.
