Halogen infrared heating lamps
When halogen gas is electrified, it releases short-wave infrared rays (wavelength 1.1-3 micrometers). The light has a high color temperature and strong brightness, which may cause visual fatigue or even eye damage. It heats up quickly, but the heat is concentrated on the surface, easily leading to a local heating phenomenon where the outside is hot and the inside is cold.
Carbon fiber heating tube
It generates heat through carbon fiber filaments and emits far-infrared rays (wavelength 5-14㎛). The light is soft and has strong penetration, capable of evenly heating the interior of objects. The infrared radiation efficiency is over 70%, and it has a high absorption rate for organic matter, making it suitable for scenarios requiring penetrating heating, such as food processing.
category | wavelength | feature | advantage | shortcoming | Match objects | Application scenarios |
Halogen | 1.1-3㎛ | The high color temperature and brightness of the light may cause visual fatigue and eye glare Heat is easily concentrated on the surface | Short term rapid heating | Heat is easily concentrated on the surface | spray painting | Car spray painting and drying, plastic vacuum forming |
