Introduction to IR Infrared LED Industry

What is IR Infrared LED?

The IR infrared LED, also known as the infrared light-emitting diode, is a type of semiconductor device that emits infrared light when an electric current is applied. It is widely used in various fields such as consumer electronics, medical equipment, industrial automation, and automotive. The IR infrared LED is a key component in the infrared detection system, which has become an essential part of modern life.

Working Principle of IR Infrared LED

The working principle of the IR infrared LED is based on the photoelectric effect. When the forward voltage is applied to the diode, electrons and holes are generated in the PN junction, and the electrons and holes recombine in the semiconductor material, releasing energy in the form of infrared light. The wavelength of the emitted infrared light is determined by the material composition and structure of the diode.

Types of IR Infrared LED

There are mainly two types of IR infrared LEDs: near-infrared and far-infrared. The near-infrared LED has a shorter wavelength and is commonly used in consumer electronics, such as remote controls, barcode scanners, and motion sensors.
