Abstract: A method of operating cold cathode in discharge lamps, including discharge lamps operating with a dielectrically hindered discharge that include two electroconducive electrodes facing each other between which a ferro-electric material is sandwiched. At least one of the electrodes presents one or more openings. When the cathode is operating, a voltage of quickly alternating polarity is applied to both electrodes, thereby freeing electrons on the surface of the ferro-electric material. The working voltage of the discharge lamp causes an acceleration of said electrons, which pass through the openings towards the anode and are used for igniting the discharge lamp and keeping it in an operating mode.
