Introduction to IR LED Emitters

IR LED emitters are semiconductor devices that emit infrared light when an electric current is applied. They are widely used in a variety of applications, including remote controls, security systems, medical devices, and consumer electronics. The primary advantage of IR LED emitters is their ability to emit light in the infrared spectrum, which is not visible to the human eye but can be detected by sensors and cameras.

How IR LED Emitters Work

IR LED emitters operate on the principle of the PN junction. When an electric current passes through the junction, electrons recombine with electron holes, releasing energy in the form of photons. These photons are in the infrared spectrum, and their wavelength varies depending on the material used in the LED’s semiconductor layer. The most common materials used in IR LED emitters are AlGaAs, GaAs, and InGaAs.
