Maximize Efficiency with Advanced IR Emitter Diode Technology

IR emitter diode, also known as infrared emitting diode, is a type of semiconductor device that emits infrared radiation when an electric current passes through it. It has become an essential component in various industries due to its wide range of applications. This article aims to provide an in-depth introduction to the IR emitter diode, covering its working principle, types, applications, advantages, and challenges in the industry.

Working Principle of IR Emitter Diode

The working principle of an IR emitter diode is based on the forward bias operation of a semiconductor diode. When a forward bias voltage is applied to the diode, electrons from the n-type semiconductor region are injected into the p-type semiconductor region. As these electrons recombine with holes in the p-type region, they release energy in the form of infrared radiation. The intensity and wavelength of the emitted infrared radiation depend on the material composition and the forward bias voltage applied to the diode.
