Abstract
A passive anti-arcing protection components for electronic ballasts of fluorescent lamps. This protection component is a bridge-rectifier-resistor-capacitor network, containing at least a diode, a resistor, and a capacitor. The component's circuitry is electrically connected to the ballast at the lamp side, acting as a low-resistance redirection path for any sudden change in energy. When an arcing condition is about to occur, this protection circuitry absorbs the spark energy, ceasing the arcing condition.
