Halogen infrared heat lamps are a type of heat – generating device that utilizes halogen gas and infrared radiation principles. Here is a detailed look at their characteristics and applications: 1. Working principle Halogen infrared heat lamps work based on the principle of incandescent radiation. The lamp filament is usually made of tungsten. Inside the lamp, halogen gas (such as iodine or bromine) is filled. When an electric current passes through the filament, the filament heats up and emits infrared radiation due to its high temperature. The presence of halogen gas serves an important function. As the filament evaporates tungsten atoms during operation, the halogen gas reacts with the tungsten atoms. The tungsten – halogen compound formed then migrates back to the hot filament and decomposes, redepositing the tungsten back onto the filament. This halogen cycle significantly extends the life of the filament compared to traditional incandescent lamps. 2. Characteristics
  • High – temperature radiation: Halogen infrared heat lamps can reach very high temperatures, usually between 500 – 1000 °C or even higher. This enables them to emit intense infrared radiation, which is very effective for heating.
  • Fast heating speed: Due to their high – power operation and efficient radiation characteristics, they can quickly heat up the target object or area. For example, in some industrial drying applications, they can start to have a noticeable heating effect within seconds.
  • Good spectral characteristics: The infrared spectrum emitted by halogen lamps is mainly in the medium – and short – wave infrared range. This spectrum is well – absorbed by many materials, such as water, organic substances, and some metals, making it very suitable for applications such as drying and heating of these substances.
  • Compact design: Halogen infrared heat lamps are usually relatively small and compact, which makes them easy to install and integrate into various equipment and systems.
