<p><P>PROBLEM TO BE SOLVED: To solve the problem that a mounting area of an inverter transformer is large and, when a plurality of discharge lamps are lit on, a discharge lamp light-on circuit is large-sized. <P>SOLUTION: The inverter transformer comprises a first bobbin 10 and a second bobbin 20 to which terminals 15, 25 are attached respectively, a pair of cores 50, 60, a first-order coil 30 wound on the groove 14 of the first bobbin 10, and a second-order coil 40 wound on the groove 24 of the second bobbin 20. At least four grooves 24 of the second bobbin 20 are formed, and a plurality of coils 26 composed of the adjacent two grooves 24 are provided in the second bobbin 20. The second-order coil 40 is wound on the one groove 24 of each of the coils 26, and the lead wire of the second-order coil 40 is passed through the other groove 24, so that the terminal is connected to the terminal 25. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
