Abstract

A discharge lamp circuit includes a power source for creating a current flow. A ballast is electrically connected to the power source and controls the current flow produced by the power source. A capacitor is electrically connected in the ballast. At least one discharge lamp is connected in series with the capacitor. The current flow passes through the discharge lamp during normal operation of the discharge lamp circuit. The ballast includes a switching circuit, electrically connected to the capacitor and the discharge lamp. The switching circuit provides an alternate path for the current flow during a starting operation of the discharge lamp circuit. The switching circuit provides the alternate path in accordance with a charge associated with the capacitor. The charge associated with the capacitor increases when the current flow passes through the alternate path.
