Infrared tubes (quartz lamp) is a highly efficient heat source, it has a quartz bubble shell and tungsten wire, can avoid wall black and therefore cause of luminous flux decline. The advantages of these lights include high efficiency, heat transfer is fast, responsive to the control unit, and compact structure, light in weight. These lights and general double the basic structure of halogen tungsten lamp, with vertical single screw or double helix filament. On both ends of tubes by molybdenum foil seal. Filament in uniform interval, tungsten wire support, in order to prevent the filament prolapse. Level can be selected according to their different types or any ignition point position.
