China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Limit the fluorescent light and produce instant high-voltage equipment should be called ballast, hps ballasts enameled wire wrapped around the core of silicon steel making is made, with core coil, instantaneous power failure, it will self-inductance generates a high voltage electrode (filament) added to both ends of the fluorescent tube. This action is carried out alternately, when the starter (skip foam) is closed, the lamp filament current limit through the ballast conduction heat; when the starter is open, the ballast will produce a high pressure is applied to the inductance on both ends of the lamp filament, the filament emission phosphor emission of electron bombardment wall starter repeated several times on and off, and will be repeated several times to this action, thus opening the lamp. Lamp light, resistance becomes small, the starter is always left open, so that the current through the lamp, fluorescent ballasts stable worked normal light of the lamp. Ballasts in fluorescent lights work, there is always a current through prone to vibration, and may have a fever, so the ballast fluorescent, especially ballast poor quality, great sound, with a long time, but also easy to burn.
