Basic Principles of Infrared LED 5mm

An infrared LED 5mm, also known as an infrared emitting diode, is a semiconductor device that emits infrared radiation when an electric current passes through it. The "5mm" refers to the diameter of the LED's housing, which is typically 5 millimeters. The infrared radiation produced by the LED is in the invisible spectrum, ranging from 700 to 3000 nanometers. The working principle of an infrared LED 5mm is based on the P-N junction. When a forward bias voltage is applied to the diode, electrons and holes are injected into the depletion region. As these charge carriers recombine, they release energy in the form of photons. In the case of an infrared LED, the photons have energies corresponding to the infrared region of the electromagnetic spectrum.
