Introduction
The IR LED diode, also known as an infrared light-emitting diode, has become an integral part of modern technology. These diodes emit light in the infrared spectrum, which is not visible to the human eye. With the rapid development of technology, IR LED diodes have found applications in a wide range of industries, from consumer electronics to automotive and industrial sectors. This article aims to provide a comprehensive introduction to the IR LED diode industry, covering its history, technology, applications, market trends, and future prospects.
History of IR LED Diodes
The concept of infrared light was first discovered in the early 18th century by the British scientist Sir Isaac Newton. However, it was not until the late 19th century that the first infrared diode was invented. In 1907, German physicist Hans Friedrich Göttinger was the first to demonstrate the photovoltaic effect in a semiconductor material, which laid the foundation for the development of IR LED diodes.
In the 1950s, American physicist Nick Holonyak Jr. made a significant breakthrough by inventing the first practical IR LED diode. Since then, the technology has been continuously improved, and the efficiency and performance of IR LED diodes have been greatly enhanced. Today, IR LED diodes are widely used in various fields due to their excellent performance and low cost.
Technology of IR LED Diodes
IR LED diodes are made of semiconductor materials, such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide phosphide (InGaAsP). These materials have the unique property of emitting infrared light when an electric current is applied.
The basic structure of an IR LED diode consists of a p-n junction, which is formed by doping a semiconductor material with impurities. When an electric current is applied to the diode, electrons and holes are injected into the p-n junction. As these charge carriers recombine, they release energy in the form of infrared light.
The performance of an IR LED diode is determined by several factors, including the material composition, doping concentration, and device structure. Advances in material science and device technology have led to the development of high-efficiency, high-brightness, and low-power IR LED diodes.
