With the rapid development of technology, infrared infrared LED (IR LED) has become an essential component in various applications, ranging from consumer electronics to industrial automation. This article aims to provide a comprehensive introduction to the IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History of IR Infrared LED

The concept of infrared light has been known for centuries, but it was not until the late 19th century that infrared radiation was discovered. The development of IR LED technology can be traced back to the early 20th century when the first infrared diodes were invented. Over the years, significant advancements have been made in the efficiency, lifespan, and cost-effectiveness of IR LEDs, making them a crucial component in numerous industries.

Technology of IR Infrared LED

IR infrared LEDs are semiconductor devices that emit infrared light when an electric current passes through them. They are made of materials such as gallium arsenide (GaAs), gallium phosphide (GaP), and aluminum gallium arsenide (AlGaAs). The key to the operation of an IR LED lies in the bandgap of the semiconductor material, which determines the wavelength of the emitted light.

IR LEDs are categorized based on their emission spectrum, which ranges from near-infrared (NIR) to far-infrared (FIR). NIR LEDs have a shorter wavelength, typically between 780 to 1600 nm, and are commonly used in consumer applications such as remote controls and barcode scanners. FIR LEDs have a longer wavelength, typically between 1600 to 3000 nm, and are used in industrial applications such as thermal imaging and night vision.

Applications of IR Infrared LED

IR infrared LEDs find applications in a wide range of fields, thanks to their ability to emit light in the infrared spectrum. Some of the most common applications include:
