Infrared transmitter light emitting diode, commonly known as IR LED, is a crucial component in the field of optoelectronics. As a semiconductor device, it emits infrared light when an electric current passes through it. This technology has been widely used in various applications, such as remote controls, security systems, and communication devices. This article aims to provide an in-depth introduction to the infrared transmitter light emitting diode industry, covering its working principle, applications, market trends, and future prospects.

Working Principle of Infrared Transmitter Light Emitting Diode

The infrared transmitter light emitting diode is a semiconductor device that consists of a PN junction. When an electric current passes through the diode, the electrons and holes in the PN junction recombine, releasing energy in the form of photons. These photons have a longer wavelength than visible light, making them invisible to the human eye. The wavelength of the emitted infrared light can vary depending on the material and structure of the diode.

There are two types of infrared light emitting diodes based on their emission spectrum: near-infrared (NIR) and far-infrared (FIR). NIR LEDs have a shorter wavelength, typically ranging from 780 to 1400 nanometers, while FIR LEDs have a longer wavelength, typically ranging from 1400 to 3000 nanometers. The choice of the type of infrared LED depends on the specific application requirements.
