Infrared LED light, also known as infrared emitting diode, is a type of light-emitting diode that emits infrared light. With the rapid development of technology, infrared LED lights have been widely used in various fields such as consumer electronics, medical equipment, and industrial automation. This article will introduce the basic concepts, application fields, and market trends of infrared LED lights.

Basic Concepts of Infrared LED Light

Infrared LED light is a semiconductor device that emits infrared light when an electric current is applied. It consists of a semiconductor material, a p-n junction, and an encapsulation. The semiconductor material is usually gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium arsenide (AlGaAs). The p-n junction is formed by doping the semiconductor material with impurities, and the encapsulation is used to protect the LED and improve its performance.

Infrared LED light has a wavelength range of 780nm to 3μm, which is longer than visible light and can not be perceived by the human eye. It can be divided into short-wave infrared, middle-wave infrared, and long-wave infrared according to its wavelength. The short-wave infrared has a wavelength of 780nm to 1.4μm, the middle-wave infrared has a wavelength of 1.4μm to 3μm, and the long-wave infrared has a wavelength greater than 3μm.

Application Fields of Infrared LED Light

Infrared LED lights have a wide range of applications due to their unique characteristics. The following are some typical application fields:

Consumer Electronics

Infrared LED lights are widely used in consumer electronics, such as remote controls, TV backlights, and digital cameras. The remote control is the most common application, where infrared LED lights are used to transmit signals to the remote control receiver. The TV backlight is also an important application, where infrared LED lights are used to illuminate the screen and improve the contrast ratio.

Medical Equipment

Infrared LED lights are used in medical equipment for various purposes, such as wound healing, pain relief, and physiotherapy. Infrared light can promote blood circulation, improve metabolism, and accelerate tissue repair. Therefore, infrared LED lights are widely used in infrared saunas, infrared lamps, and other medical equipment.

Industrial Automation

Infrared LED lights are widely used in industrial automation for sensing, detection, and control. They can be used to detect the presence or absence of objects, measure distances, and control the movement of machinery. Infrared LED lights have high sensitivity, fast response speed, and strong anti-interference ability, which make them suitable for various industrial applications.

Security and Surveillance

Infrared LED lights are used in security and surveillance systems for night vision and infrared detection. They can capture images in low-light conditions and detect human movements, making them an important part of security systems.
