Infrared LED light, also known as infrared diode, has become an integral part of various industries due to its unique properties and applications. This article aims to provide a comprehensive introduction to the infrared LED light industry, covering its history, technology, applications, market trends, and future prospects.
History of Infrared LED Light
The concept of infrared light has been known since ancient times, but it was not until the early 20th century that infrared LED technology was developed. The first infrared LED was invented by Nick Holonyak Jr. in 1962 at General Electric. Since then, the technology has undergone significant advancements, making it more efficient and cost-effective.
Technology of Infrared LED Light
Infrared LED light is a semiconductor device that emits infrared radiation when an electric current passes through it. The process involves the injection of electrons and holes into the semiconductor material, which then recombine, releasing energy in the form of infrared light. The color of the light emitted depends on the semiconductor material used.
There are different types of infrared LEDs, including near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR). Each type has its own wavelength range and applications. For example, NIR LEDs are commonly used in remote controls, while FIR LEDs are used in thermal imaging and night vision devices.
