Introduction to IR LED Industry

What is an IR LED?

An infrared light-emitting diode (IR LED) is a type of semiconductor device that emits infrared light when an electric current is applied. It is widely used in various applications, such as remote controls, communication systems, and optical sensors. IR LEDs have become an essential component in modern technology due to their compact size, low power consumption, and high efficiency.

History of IR LED

The concept of the infrared LED was first proposed by Nick Holonyak Jr. in 1962 while working at General Electric. In the following years, the technology has evolved significantly, and IR LEDs have become more efficient and reliable. Today, IR LEDs are produced in large quantities and are used in various industries worldwide.

Types of IR LEDs

There are several types of IR LEDs, each with its unique characteristics and applications. The most common types include: 1. Near-Infrared (NIR) LEDs: These LEDs emit light in the range of 750 to 1500 nm. They are used in applications such as optical communication, remote controls, and medical imaging. 2. Mid-Infrared (MIR) LEDs: These LEDs emit light in the range of 1500 to 3000 nm. They are used in applications such as thermal imaging, gas sensing, and night vision. 3. Far-Infrared (FIR) LEDs: These LEDs emit light in the range of 3000 to 10000 nm. They are used in applications such as infrared heating, thermal imaging, and remote sensing.
