たことを特徴とする冷陰極蛍光管の点灯装置。 A lighting device that turns on and off a switching element connected to the primary side of a transformer at a required cycle to obtain an AC output on the secondary side, and applies this to the electrodes at both ends of a cold cathode fluorescent lamp via a current limiter. In this case, an auxiliary electrode cord was arranged in the tube axis direction along the outside surface of the tube so that it fell within a range corresponding to the length of the electrodes at both ends of the cold cathode fluorescent tube, and was connected to a position closer to the power source than the current limiting section. A cold cathode fluorescent lamp lighting device characterized by:
