Infrared emitter tube, also known as infrared diode, is a key component in the field of infrared technology. As a semiconductor device, it emits infrared light by converting electrical energy into light energy. With the continuous development of infrared technology, infrared emitter tubes have been widely used in various fields, such as security monitoring, automotive lighting, medical treatment, and industrial automation. This article will introduce the industry of infrared emitter tubes, including its development history, application fields, and future trends.

Development History of Infrared Emitter Tube

The development of infrared emitter tubes can be traced back to the early 20th century. In 1908, German physicist Heinrich Hertz first observed the phenomenon of infrared emission in a vacuum tube. In the 1930s, infrared diodes were first produced, and they were mainly used in the field of television. With the continuous development of semiconductor technology, infrared emitter tubes have been gradually improved in terms of performance and application fields.

In the 1950s, with the development of solid-state devices, infrared emitter tubes began to be widely used in various fields. At this stage, the main materials of infrared emitter tubes were selenium and tellurium. In the 1970s, with the rapid development of semiconductor materials, gallium arsenide (GaAs) and gallium phosphide (GaP) began to be used as the main materials of infrared emitter tubes. This has greatly improved the performance and application range of infrared emitter tubes.

Application Fields of Infrared Emitter Tube

Infrared emitter tubes have been widely used in various fields due to their excellent performance. The following are some of the main application fields of infrared emitter tubes:

1. Security Monitoring

Infrared emitter tubes are widely used in security monitoring systems. They can be used to emit infrared light, and the infrared light reflected by the object can be received by the infrared sensor, so as to achieve the purpose of monitoring and identifying objects. Infrared emitter tubes are particularly suitable for night-time monitoring and long-distance monitoring.

2. Automotive Lighting

Infrared emitter tubes are used in automotive lighting systems, mainly for infrared night vision. By emitting infrared light, the infrared night vision system can identify obstacles in the dark, which is very important for driving safety.

3. Medical Treatment

Infrared emitter tubes are also used in medical treatment. For example, in infrared therapy, infrared emitter tubes emit infrared light to stimulate the human body's metabolism and improve the body's immunity.

4. Industrial Automation

Infrared emitter tubes are widely used in industrial automation. They can be used for object detection, position control, and distance measurement, which can greatly improve the efficiency and accuracy of industrial production.
