This article aims to provide a comprehensive introduction to the 850nm infrared LED industry, covering its history, technology, applications, market trends, and future prospects.

History of Infrared LEDs 850nm

The development of infrared LEDs dates back to the 1960s when the first infrared diodes were invented. However, it was not until the 1980s that 850nm infrared LEDs gained popularity due to their superior performance and lower cost compared to other infrared diodes. Since then, the 850nm infrared LED industry has witnessed significant growth and innovation.

Technology of Infrared LEDs 850nm

Infrared LEDs with a wavelength of 850nm are based on gallium arsenide (GaAs) or gallium indium phosphide (GaInP) semiconductor materials. These materials have a direct bandgap, which allows them to emit infrared light efficiently. The key factors affecting the performance of 850nm infrared LEDs include the quality of the semiconductor material, the design of the LED structure, and the manufacturing process. The typical structure of an 850nm infrared LED consists of a p-n junction, which is formed by doping the semiconductor material with impurities. The p-type layer is rich in holes, while the n-type layer is rich in electrons. When an electric current is applied to the LED, electrons and holes recombine at the p-n junction, releasing energy in the form of infrared light.
