Abstract: The present invention relates to a string lamp. The string lamp includes a bulb, a lamp holder, a hollow connecting base and a capacitor embedded in the connecting base in a separable mode. A lower part of the bulb is contained in the lamp holder. At least two lamp pins extend out from wire holes formed in the lower part of the lamp holder. The inner side wall of the connecting base is provided with at least two separately arranged conductive pieces, and the conductive pieces are electrically contacted with the corresponding lamp pins. The capacitor is arranged below the lamp holder, and connecting pins of the capacitor are electrically contacted with the corresponding conductive pieces as well. The string lamp of the present invention is compact in structure, and the capacitor and the lamp holder are convenient to maintain and replace.

Abstract: A light string includes a plurality of lights and a plurality of non-polarity capacitor corresponding to the lights; wherein, the lights are electrically connected in series and to be powered by an AC power supply; each of the non-polarity capacitor is connected in parallel to a corresponding one of the lights. When the light string is powered on, the non-polarity capacitor is charged and absorbs the surge current which may occur. Thus, the voltage dropped on each light rises slowly and the lights are safe. The non-polarity capacitor also performs power compensation and electrical connection.
