Electric discharge lamp lighting unit

摘要

An electric discharge lamp lighting device wherein a high voltage generating transformer 10 comprises a secondary coil 13 wound on an outer side of a laminated core 12 disposed in the center of a bobbin 11 and a primary coil 14 wound on an outer side of said secondary coil 13. A high voltage output terminal 13a of said secondary coil 13 is connected to a high voltage terminal of an HID lamp through a terminal 12a of a laminated core 12. A low voltage input terminal 13b of said secondary coil 13 is connected to a primary coil 14. As a result, insulation volume can be reduced and a reduction in the size of the device can be achieved.
