With the rapid development of technology, infrared LED light has become an indispensable part of our daily lives. This article will introduce the industry of infrared LED light, including its history, types, applications, and future development trends.

History of Infrared LED Light

The history of infrared LED light dates back to the early 20th century. In 1900, German physicist Heinrich Hertz discovered the phenomenon of infrared radiation. Later, in 1917, American physicist William Henry Brewster successfully developed the first infrared diode. Since then, the research and development of infrared LED light have been rapidly progressing.

Types of Infrared LED Light

Infrared LED light can be divided into two main types: near-infrared (NIR) and far-infrared (FIR). NIR has a wavelength range of 0.75 to 1.4 micrometers, while FIR has a wavelength range of 1.4 to 1000 micrometers. Both types of infrared LED light have their own characteristics and applications.

Applications of Infrared LED Light
