IR emitter diode, also known as infrared emitting diode, is a type of semiconductor device that emits infrared radiation when an electric current is applied. It is widely used in various fields such as consumer electronics, automotive, medical, and industrial applications. In this article, we will provide an in-depth introduction to the industry of IR emitter diodes, covering their working principle, types, applications, market trends, and future prospects.

Working Principle of IR Emitter Diode

The working principle of an IR emitter diode is based on the P-N junction. When an electric current is applied to the diode, electrons from the N-type semiconductor are injected into the P-type semiconductor. Due to the difference in energy levels between the two types of semiconductors, the electrons recombine with holes, releasing energy in the form of infrared radiation. The intensity of the emitted infrared radiation is proportional to the electric current passing through the diode.
