Definition and Classification of Infrared Emitter LED

Infrared emitter LED, also known as infrared LED, is a type of semiconductor device that emits infrared light. It is mainly composed of a p-n junction and an infrared emitting layer. According to the wavelength of the emitted light, infrared emitter LED can be divided into near-infrared, mid-infrared, and far-infrared. The near-infrared range is between 700nm and 1500nm, the mid-infrared range is between 1500nm and 3000nm, and the far-infrared range is between 3000nm and 1mm.

Working Principle of Infrared Emitter LED

The working principle of infrared emitter LED is based on the photoelectric effect. When the forward voltage is applied to the p-n junction, electrons and holes are injected into the active layer. Under the action of the electric field, electrons and holes recombine, releasing energy in the form of photons. These photons have a wavelength in the infrared range, which is emitted from the LED chip.
