Introduction to Infrared Emitter LED

What is an Infrared Emitter LED?

Infrared emitter LED, also known as infrared LED, is a type of light-emitting diode that emits infrared light. It is widely used in various fields, such as remote control, infrared communication, infrared detection, and so on. The infrared emitter LED has the advantages of small size, low power consumption, and long service life, making it an important component in the infrared field.

Working Principle of Infrared Emitter LED

The working principle of an infrared emitter LED is similar to that of a common LED. It consists of a p-n junction, and when the diode is forward biased, electrons and holes are injected into the depletion layer. Under the action of the electric field, electrons and holes recombine and release energy in the form of photons. The photons with wavelengths between 700nm and 1400nm are infrared light, which is the main emission range of infrared emitter LED.
