Claims

[Claims for Utility Model Registration] A first transformer core in which a central axis and a discontinuous peripheral wall protrude from a plate-like end portion in the same direction and at the same height, and a central axis and peripheral wall of the first transformer core. a printed circuit board with a perforation passing through the tip of the part; a primary coil patterned on the surface of the printed circuit board surrounded by the perforation; and a first transformer core passing through the perforation of the printed circuit board. a second transformer core joined to the central axis and the end face of the peripheral wall; and a circle installed in a stack on the primary coil and housed within the central axis and peripheral wall of the first transformer core and/or the second transformer core. A transformer for an EL lighting power supply, characterized by comprising a ring-shaped secondary coil.
