Abstract

PURPOSE:To reduce the used amount of a steel plate by specifying the size of grooves for filling primary and secondary windings of a core used for the stabilizer for the discharge lamp used for 2 lamps lighting equipment and thus reducing the scraps without decreasing the characteristics thereof. CONSTITUTION:When a side leg steel plate 1 is stamped from a steel plate 10, follow the steps below. That is, outer legs 2 and 3 having a legnth D and a width W are formed at the rectilinear part 13 disposed at outside, and coil filling groove having a length (d-DELTAd) and a width W are formed adjacent to the leg 2 at the part 13. Further, a groove having a length (d) and a width W is formed adjacent to the leg 3 at the part 13, and a groove having a length (d) and a width 2W is formed at the part 13 between these two grooves. Then, a primary winding T1 is wound on the central leg A prepared separately, and secondary windings T21, T22 are also wound on the leg A as disposed at both sides of the winding T1, and a pair of steel plates 1 stamped previously are brouht into contact with both sides of the leg A while filling the windings in the grooves.
