Infrared emitter tube, also known as infrared radiation tube, is an important component in the field of infrared technology. It converts electrical energy into infrared radiation, which has a wide range of applications in various industries. This article will introduce the basic concepts, types, applications, and future development trends of infrared emitter tubes.

Basic Concepts of Infrared Emitter Tube

An infrared emitter tube is a device that emits infrared radiation by converting electrical energy into heat energy. It usually consists of a cathode, anode, and an infrared emitting material. When an electrical current passes through the tube, the cathode emits electrons, which are accelerated by the electric field and collide with the anode. During the collision, the electrons transfer energy to the infrared emitting material, resulting in the emission of infrared radiation. Infrared radiation is a type of electromagnetic wave with a wavelength longer than visible light but shorter than terahertz radiation. It is characterized by its strong thermal effect, which can be used for heating, detection, and communication purposes. Infrared emitter tubes can emit infrared radiation in the near-infrared, mid-infrared, and far-infrared regions, depending on the material and structure of the tube.

Types of Infrared Emitter Tubes

There are various types of infrared emitter tubes, which can be classified according to their materials, structures, and applications. The following are some common types: 1. Thermionic infrared emitter tube: This type of tube utilizes the thermionic emission principle to generate infrared radiation. The cathode is typically made of tungsten or other metals with high melting points. When the cathode is heated to a certain temperature, electrons are emitted and accelerated by the electric field, resulting in the emission of infrared radiation. 2. Phosphorescent infrared emitter tube: This type of tube utilizes the phosphorescent emission principle to generate infrared radiation. The cathode is coated with a phosphorescent material, which emits infrared radiation when excited by electrons. The advantage of this type of tube is that it has a longer lifetime and higher radiation efficiency compared to thermionic infrared emitter tubes. 3. LED infrared emitter tube: This type of tube utilizes the LED (Light Emitting Diode) principle to generate infrared radiation. The cathode is made of a semiconductor material, which emits infrared radiation when an electrical current passes through it. LED infrared emitter tubes have the advantages of low power consumption, high radiation efficiency, and long service life. 4. Semiconductor infrared emitter tube: This type of tube utilizes the semiconductor principle to generate infrared radiation. The cathode is made of a semiconductor material, which emits infrared radiation when an electrical current passes through it. Semiconductor infrared emitter tubes have high radiation efficiency, wide spectral range, and can be used in various applications.
