With the rapid development of technology, the demand for infrared light emitters has been increasing in various fields, including automotive, medical, industrial, and consumer electronics. An infrared light emitter, also known as an IR LED, is a device that emits infrared radiation, which is invisible to the human eye. This article aims to provide an in-depth introduction to the IR light emitter industry, covering its history, types, applications, and future trends.

History of IR Light Emitters

The concept of infrared light was discovered by Sir Isaac Newton in the 17th century, but it was not until the late 19th century that the first practical infrared light emitter was developed. In 1898, German physicist Hermann von Helmholtz successfully produced infrared light using a selenium cell. This breakthrough laid the foundation for the development of infrared light emitters in various fields.

Over the years, the technology of IR light emitters has evolved significantly. In the early 20th century, the development of selenium and cadmium sulfide as infrared light-emitting materials revolutionized the industry. Today, IR light emitters are widely used in various applications, thanks to continuous advancements in materials science, device design, and manufacturing processes.
