ABSTRACT:
A cold cathode lamp includes a light-transmitting insulating tube, first and second internal electrodes arranged inside the insulating tube, first and second external electrodes arranged outside the insulating tube and respectively connected with the first and second internal electrodes, first and second insulating bodies respectively covering the first and second external electrodes, a first counter electrode arranged opposite to the first external electrode via the first insulating body, and a second counter electrode arranged opposite to the second external electrode via the second insulating body. The first (second) counter electrode has a portion which does not face the first (second) external electrode, and the space between this portion and the insulating tube is filled with the first (second) insulating body. A plurality of such cold cathode lamps can be lit by being connected in parallel with a power supply. In addition, generation of corona discharge near the outer peripheries of the counter electrodes can be suppressed.
