<p>PROBLEM TO BE SOLVED: To obviate a high tension cable, reduce a voltage loss, and prevent a malfunction by housing a lighting transformer in a main body case, connecting a secondary coil of the lighting transformer to a terminal arranged in a socket part protrusively arranged in the main body case, and connecting a primary coil of the lighting transformer to an external cable way. SOLUTION: A socket piece 20a is composed of an installing base part 21 to engage with its inside edge and a cylindrical connecting part 22 continuously formed on a front face of the installing base part 21. A high electric potential side connecting terminal 23 is installed in the center of the connecting part 22, and a low electric potential side connecting terminal 24 is installed along an inner peripheral surface of the connecting part 22, and is protruded so that lead wires can be respectively connected from a back face of the installing base part 21. In a lighting transformer 30a, its outside is covered with a core casing 31a, and is constituted by installing a coil bobbin, a secondary coil and a primary coil in the core casing 31a, and the respective lead wires are extracted. By being constituted in this way, a single structure is formed by continuously forming an iron core part, and a high tension cable is obviated.</p> |
