Infrared LED diodes have become an essential component in various industries due to their ability to emit infrared light. This article provides an in-depth introduction to the infrared LED diode industry, covering its history, technology, applications, market trends, and future prospects.

History of Infrared LED Diodes

The concept of infrared light was first discovered by the British scientist Willian Herschel in 1800. However, it was not until the 1960s that infrared LED diodes were developed. The invention of the infrared LED diode was a significant breakthrough in optoelectronics, as it provided a compact, efficient, and reliable source of infrared light. Since then, the infrared LED diode industry has experienced rapid development and has become an indispensable part of our daily lives.

Technology of Infrared LED Diodes

Infrared LED diodes are semiconductor devices that emit infrared light when an electric current is applied. The core of the infrared LED diode is a PN junction, which is formed by the combination of a p-type semiconductor and an n-type semiconductor. When the forward voltage is applied to the PN junction, electrons and holes are injected into the depletion region, and the recombination of electrons and holes generates infrared light. The main parameters of an infrared LED diode include forward voltage, forward current, light output, and wavelength. The forward voltage and forward current determine the operating conditions of the infrared LED diode, while the light output and wavelength determine its application range. With the continuous development of technology, the performance of infrared LED diodes has been greatly improved, and the efficiency and stability of the devices have been significantly enhanced.
