Innovative InfraredEmitter LED Technology: Advancements and Applications Unveiled

Infrared emitter LED, or infrared emitting diode, is a type of light-emitting diode that emits infrared light. This technology has been widely used in various fields such as consumer electronics, automotive, medical equipment, and industrial automation. In this article, we will explore the history, working principle, applications, and future trends of infrared emitter LED.

History of Infrared Emitter LED

The development of infrared emitter LED can be traced back to the early 20th century. In 1900, British physicist Lord Kelvin predicted the existence of infrared radiation. In the 1930s, the first infrared emitting diode was developed by an American physicist named Oleg Losev. Since then, the technology has been continuously improved and developed, and it has been widely used in various fields.

Working Principle of Infrared Emitter LED

Infrared emitter LED works based on the principle of semiconductor physics. When a forward voltage is applied to the diode, electrons and holes are injected into the depletion region, where they recombine and release energy in the form of infrared light. The color of the emitted light depends on the bandgap of the semiconductor material used in the diode.

The bandgap of a semiconductor material determines the energy level of the electrons and holes. A smaller bandgap results in lower energy levels and longer wavelengths of emitted light, while a larger bandgap results in higher energy levels and shorter wavelengths. Therefore, the material composition and structure of the infrared emitter LED are crucial in determining the wavelength and intensity of the emitted light.
