Abstract
Abstract A cordless conducting means for lamps including two half-casings, bent conductors on which a circumferential slots are arranged and two pairs of positioning means which are conductive. The conductors are retained in the positioning means so that electricity can be transmitted via the conductors and the positioning means finally to the bulb. A coat of insulating material is coated on the conductors in order to prevent electrical leakage.
