Infrared transmitter light emitting diode (IR LED) has become an essential component in various industries due to its unique properties and wide applications. As a semiconductor device, IR LED can emit infrared light with a specific wavelength, which is invisible to the human eye. This article aims to provide an in-depth introduction to the IR LED industry, covering its history, working principle, applications, market trends, and future prospects.

History of Infrared Transmitter Light Emitting Diode

The concept of light-emitting diode (LED) was first proposed by Oleg Vladimirovich Losev in 1927. However, it was not until the 1960s that the first practical IR LED was developed by Nick Holonyak Jr. at General Electric. Since then, IR LED technology has undergone significant advancements, and it has been widely used in various fields.

Working Principle of Infrared Transmitter Light Emitting Diode

The working principle of an IR LED is based on the forward bias operation of a semiconductor diode. When a forward voltage is applied to the diode, electrons and holes are injected into the active region. Due to the recombination of electrons and holes, photons are emitted, which correspond to the infrared region of the electromagnetic spectrum. The wavelength of the emitted infrared light can be tuned by adjusting the composition and structure of the semiconductor material.
