Infrared emitter tube, also known as infrared light-emitting diode (LED), is an electronic component that emits infrared light. With the continuous development of infrared technology, infrared emitter tubes have been widely used in various fields, such as home appliances, medical equipment, industrial automation, and security monitoring. This article will introduce the basic knowledge, application fields, and development trends of infrared emitter tubes.

Basic Knowledge of Infrared Emitter Tube

Infrared emitter tube is a semiconductor device that emits infrared light. It is mainly composed of a semiconductor material, a p-n junction, and a package. When the forward voltage is applied to the p-n junction, electrons and holes recombine, and infrared light is emitted in the process of recombination. The color of the emitted light depends on the material of the semiconductor. Commonly used materials include gallium arsenide (GaAs), gallium phosphide (GaP), and indium antimonide (InSb).

Classification of Infrared Emitter Tube

Infrared emitter tubes can be divided into several categories according to different criteria:

• According to the emission wavelength: short-wave infrared emitter tube, medium-wave infrared emitter tube, and long-wave infrared emitter tube.
• According to the emitting material: GaAs infrared emitter tube, GaP infrared emitter tube, and InSb infrared emitter tube.
• According to the package form: ceramic package, plastic package, and metal package.
