The frame-shaped halogen heating lamp is a special shape of heating lamp.
It is frame-shaped with a halogen lamp tube inside. Halogen lamps are made by injecting halogen gas such as iodine or bromine into the bulb. When working, after the filament is heated, the tungsten atoms sublimate at high temperature and react with the halogen to generate tungsten halides. The tungsten halides diffuse to the vicinity of the filament and decompose again, allowing tungsten to be re-deposited on the filament. This cycle process extends the service life of the filament.
The frame-shaped design allows its heating area to be flexibly distributed according to the shape. It is generally used for industrial heating, such as local plastic thermoforming and food drying. It is also used for space heating in some commercial places. It can provide relatively concentrated heat and has relatively high heating efficiency.
