ABSTRACT:
A cold cathode tube lamp is fed with power from a first conductive member and a second conductive member provided outside in a mounted state, and includes a glass tube, first and second internal electrodes provided inside the glass tube, a first external electrode provided outside the glass tube and connected to the first internal electrode, a second external electrode provided outside the glass tube and connected to the second internal electrode, a first insulating layer coated on the first external electrode, and a second insulating layer coated on the second external electrode. In a mounted state, the first conductive member and the first external electrode are capacitively coupled together, and the second conductive member and the second external electrode are capacitively coupled together. With such a structure, parallel lighting can be achieved by parallel driving.
