How 5mm Infrared LED Diodes Work

An Infrared LED diode is a semiconductor device that emits infrared light when an electric current passes through it. The 5mm size refers to the diameter of the diode's package, which is just 5 millimeters. The process of generating infrared light involves the following steps: 1. Electric current is applied to the diode. 2. The electric current excites the electrons in the semiconductor material. 3. As the electrons recombine with the holes in the material, they release energy in the form of photons. 4. These photons have a longer wavelength than visible light, making them infrared. The 5mm Infrared LED diode is designed to emit a specific wavelength of infrared light, which is determined by the semiconductor material used in its construction. Common materials include AlGaAs, GaAs, and InGaAs.
