Abstract
A light string includes a number of lights. The lights are electrically connected in series and powered by an AC power supply. At least one capacitor is connected in parallel to one of the lights. Each light or a part of lights of the light string of the present invention is electrically connected in parallel to a capacitor. When the light string is powered on, the capacitor is charged and absorbs a surge current which may occur. Thus, the voltage dropped on each light rises slowly and the lights are safe. The capacitor also performs power compensation and electrical connection. When the filament of the light bulb fails and the bulb remains in the light string, or when the bulb is removed from its socket for replacement, the closed path for flow of electrical current is still closed.
