Title:
IGNITOR TRANSFORMER, AND DISCHARGE LAMP IGNITING DEVICE THAT DOES NOT USE MERCURY
Document Type and Number:
WIPO Patent Application WO/2011/039801
Kind Code:
A1
Abstract:
An ignitor transformer comprises: a primary winding (1) comprising a plurality of conductive wires and discharging electric charges charged within a capacitor (34); and a secondary winding (2) comprising a number of conductive wires less than the number of conductive wires of the primary winding and supplying, to a mercury-free bulb (32), high voltage pulses generated due to discharging by the primary winding (1). By providing the primary winding, which is stacked up to not more than two layers, and the secondary winding (2) side by side at the bottom face of a U-shaped terminal (3), bending both sides of the U-shaped opening, and performing fusing, the primary winding (1) and the secondary winding (2) are electrically connected at the same time. This enables reliable electrical connection of both the windings (1, 2) to the terminal (3), without increasing the size of the terminal (3), and without any falling-off of the windings.
