Introduction

The infrared emitter LED, also known as an infrared emitting diode, has become an essential component in various applications, including remote controls, security systems, and communication technologies. This article aims to provide an in-depth introduction to the infrared emitter LED industry, covering its history, working principle, applications, market trends, and future prospects.

History of InfraredEmitter LED

The concept of the infrared emitter LED dates back to the early 20th century. In 1908, a Russian physicist named Oleg Losev discovered that when certain materials were excited with electricity, they emitted infrared radiation. This discovery laid the foundation for the development of infrared emitting diodes. In the 1960s, the first practical infrared emitting diodes were developed by a team of engineers at RCA. These diodes were based on gallium arsenide (GaAs) and gallium phosphide (GaP) materials. Over the years, advancements in semiconductor technology have led to the development of various types of infrared emitter LEDs, such as AlGaAs, InGaAs, and InGaN.

Working Principle of InfraredEmitter LED

Infrared emitter LEDs work on the principle of electroluminescence. When an electric current is applied to the diode, electrons and holes are injected into the semiconductor material. As these charge carriers recombine, they release energy in the form of photons. The energy released corresponds to the energy gap of the semiconductor material, which determines the wavelength of the emitted light. In the case of infrared emitter LEDs, the emitted light falls within the infrared spectrum, which is not visible to the human eye. The infrared radiation can be used for various applications, such as wireless communication, remote sensing, and security systems.
