Background

Halogen lamps are one type of incandescent lamps. The principle is to inject halogen gas such as iodine or bromine into the bulb. Under high temperature, the sublimed tungsten filament and halogen perform chemical action, and the sublimed tungsten can be re-solidified on the tungsten filament to form balanced circulation, so that premature breakage of the tungsten filament is avoided. Therefore, the halogen lamp has longer service life than the common incandescent lamp, and the halogen lamp works at higher temperature than the common incandescent lamp, and has higher brightness and efficiency.
