Infrared LED light, also known as infrared LED, is a type of light-emitting diode that emits infrared light. As a key component in the infrared spectrum, it has been widely used in various fields such as consumer electronics, medical equipment, and industrial automation. This article will introduce the industry of infrared LED light, including its working principle, applications, and market prospects.

Working Principle 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 p-n junction, where electrons and holes are recombined, releasing energy in the form of infrared light. The infrared light emitted by the LED is in the invisible range of the human eye, with wavelengths ranging from 700 to 3000 nanometers.

The working principle of infrared LED light can be described in the following steps:

1. When the positive voltage is applied to the p-side and the negative voltage is applied to the n-side, the p-n junction is forward-biased, and the electrons and holes are injected into the depletion region.
2. In the depletion region, the electrons and holes are recombined, and the energy released during the recombination is in the form of infrared light.
3. The infrared light emitted by the LED passes through the lens and is emitted out.

Applications of Infrared LED Light

Infrared LED light has a wide range of applications due to its unique characteristics, such as low power consumption, small size, and fast response time. The following are some common applications of infrared LED light:

For example, the infrared remote control used in TVs and air conditioners is a typical application of infrared LED light.

Medical Equipment

Infrared LED light is also used in medical equipment, such as endoscopes, laser therapy devices, and infrared thermometers. It can be used for imaging, therapy, and temperature measurement. For example, the infrared endoscope used in gastrointestinal endoscopy can help doctors diagnose diseases without surgery.

Industrial Automation

Infrared LED light is used in industrial automation for various purposes, such as optical switches, distance sensors, and barcode readers. It can be used for detecting, positioning, and controlling industrial equipment. For example, the infrared sensor used in automatic doors can detect the presence of people and open the door automatically.
