Description
Technical Field

Background
The ballast is a device which plays a role in current limiting and generating instant high voltage on the fluorescent lamp, and is made by winding enameled wires on an iron core made of silicon steel, and when the coil with the iron core is powered on/off instantly, the coil can generate high voltage by self induction and is added on electrodes (filaments) at two ends of the fluorescent lamp tube. This action is performed alternately, when the starter (jump bulb) is closed, the filament of the lamp tube is conducted to generate heat through the current-limiting of the ballast; when the starter is opened, the ballast will generate high voltage by self-induction and apply it to the filaments at two ends of the lamp tube, the filaments emit electrons to bombard the fluorescent powder on the tube wall to give out light, and the starter is turned on and off several times, and the lamp tube is turned on. When the lamp tube is normally lighted, the internal resistance is reduced, and the starter is always kept in an open circuit state, so that the current stably passes through the lamp tube and the ballast to work, and the lamp tube is normally lighted.
