Introduction to Diode IR Technology

Diode IR technology has been a significant development in the realm of infrared detection and emission. An infrared diode, also known as an IR LED (Infrared Light Emitting Diode), is a semiconductor device that emits infrared radiation when an electric current is applied to it. This technology has revolutionized the way we interact with devices and has become an integral part of modern life.

Working Principles of Diode IR

The working principle of a diode IR is based on the P-N junction of a semiconductor material. When an electric current is applied to the diode, electrons and holes recombine at the junction, releasing energy in the form of photons. These photons are in the infrared region of the electromagnetic spectrum, which is not visible to the human eye. The intensity of the emitted infrared light depends on the current passing through the diode and the material used in its construction.
