Abstract

Ein Zündtransformator für eine Hochdruckgasentladungslampe soll für eine automatische Fertigung optimiert werden. Hierfür wird vorgeschlagen, auf einer Außenseite des Gehäuses des Zündtransformators zwei in Längsrichtung beabstandete rampenartige Erhebungen auszubilden, über die jeweils eine Windung der Primärwicklung geführt ist. Die Erhebungen weisen ebene Flächen auf.

Figure imgaf001
An ignition transformer for a high-pressure gas discharge lamp is to be optimized for automatic production. For this purpose, it is proposed to form two longitudinally spaced ramp-like elevations on an outer side of the housing of the ignition transformer, over each of which one turn of the primary winding is guided. The surveys have flat surfaces.
