<p><P>PROBLEM TO BE SOLVED: To reduce variations of inductance of secondary wiring and of leaking inductance, and prevent uneven luminance from happening by making a lamp current uniform. <P>SOLUTION: A two output type inverter transformer is configured by winding a primary winding 12 at the center of a bobbin 10 and winding a secondary winding 14 on opposite sides of the same, and inserting a rod shaped core 16 into a winding shaft, disposing a square frame-shaped core 18 to surround peripheries of the primary and secondary winding parts, and making the rod-shaped core and the square frame-shaped core to face to each other via a gap sheet. When the length of the square frame-shaped core is assumed to be L1, the length of the rod-shaped core L2, and the thickness of the gap sheet t, L2-L1>2t is set and the rod-shaped core and the square frame shaped core are combined such that the former is more protruded than the square frame-shaped core uniformly. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
