Infrared lamp is a special lighting equipment, and its working principle is mainly based on the combination of light and heat. The main applications of this lamp include photography, medical treatment, industry and architecture, especially in those places where high precision is needed or sensitive to visible light. Understanding the working principle of infrared lamp is helpful to use this tool better and understand its performance in various applications.
First, infrared lamp and infrared light.
Infrared ray is a part of electromagnetic wave, which is located outside the red end of visible light. This means that infrared rays are invisible to our naked eyes. However, infrared is still a powerful light source, especially when it needs deep penetration or is sensitive to visible light.
Infrared light works by using this characteristic of infrared light. Its internal light-emitting diode (LED) emits infrared light, instead of our common white light. When the current passes through the LED, the electrons inside the LED will jump from the ground state to the excited state, thus releasing energy and radiating it in the form of photons. These photons are what we call infrared rays.
Second, the working principle of infrared lamp
The working process of infrared lamp can be divided into three steps: energy conversion, heating and luminescence.
Energy conversion: In infrared lamps, electric energy is converted into heat energy. This is achieved by using special electronic components and materials in the lamp. After the electric energy is converted into heat energy, the heat energy is used to heat the luminescent substance in the lamp.
Heating: When the luminescent substance is heated to a sufficient temperature, it will start to emit infrared rays. These infrared rays are what we call thermal radiation. Thermal radiation is the electromagnetic wave emitted by all objects above absolute zero.
Luminescence: Finally, these infrared rays are emitted from the emission port of the lamp in the form of straight line or diffusion. This process is what we call light emission.
Third, the application of infrared lamp
Infrared lamp IR RED can be used for samples.
Because of its special properties, infrared lamps are widely used in various occasions. In photography, infrared photography can capture scenes invisible to human eyes, such as images reflected by infrared rays on objects. In the medical field, infrared rays are used for treatment and diagnosis, such as infrared physiotherapy and infrared thermal imager. In industrial field, infrared ray is used to detect equipment failure or heat distribution. In the field of architecture, infrared rays are used to detect the thermal conductivity and other characteristics of building materials.
Fourth, summary.
Infrared lamp is a special lighting equipment, and its working principle is based on the combination of light and heat. It uses electric energy to convert into heat energy, then uses heat energy to generate infrared rays, and finally emits infrared rays in a straight line or diffusion form. Understanding the working principle of infrared lamp is helpful to use this tool better and understand its performance in various applications.
