HIGH VOLTAGE GENERATION TRANSFORMER FOR DISCHARGE LAMP LIGHTING DEVICE

摘要

A high voltage generation transformer for a discharge lamp lighting device comprises a rodlike core, a bobbin for a secondary winding divided into a plurality of sections with the core arranged in the center, a secondary winding wound while divided onto the plurality of sections of the bobbin for secondary winding, a bobbin for primary winding arranged on the outer circumferential side of the secondary winding, and a primary winding wound around the bobbin for a primary winding, wherein the thickness of the bobbin for the primary winding is varied for every section of the secondary winding or every plurality of sections such that it becomes large on the side where potential difference between the primary winding and the secondary winding is high and becomes small on the side of low potential difference.
