Revolutionizing Night Vision: The Advancements and Applications of LED Infrared LEDs

LED infrared LEDs, also known as infrared emitting diodes, have become an integral part of modern technology, offering a wide range of applications in consumer electronics, automotive, medical, and industrial sectors. These diodes emit infrared light, which is invisible to the human eye but can be detected by sensors and cameras. This article aims to provide an in-depth introduction to the LED infrared LED industry, covering its history, technology, applications, market trends, and future prospects.

History of LED Infrared LEDs

The concept of infrared light was discovered by the English scientist Willian Herschel in 1800. He observed that a prism can split sunlight into a spectrum of colors, and the longest wavelength, beyond the red, produces heat. This discovery laid the foundation for the development of infrared technology. The first infrared diodes were developed in the 1960s, and since then, they have undergone significant advancements, leading to the modern LED infrared LEDs we use today.

Technology of LED Infrared LEDs

LED infrared LEDs are made of semiconductor materials, such as gallium arsenide (GaAs), gallium phosphide (GaP), and aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to emit infrared light when an electric current is applied. The process of producing LED infrared LEDs involves epitaxial growth, which is the process of creating a thin layer of semiconductor material on a substrate. This layer is then patterned and etched to form the LED structure.

One of the key advantages of LED infrared LEDs is their high efficiency. They convert a significant portion of the electrical energy into infrared light, making them more energy-efficient than traditional infrared sources. Moreover, LED infrared LEDs have a long lifespan and are durable, which makes them suitable for various applications.
