Abstract

Ein Zündtransformator für eine Hochdruckgasentladungslampe soll für eine automatische Fertigung optimiert werden. Gasblasen in einer Vergussmasse sollen dabei vermieden werden. Hierfür wird vorgeschlagen, in der ersten Seite eine Einfüllöffnung anzuordnen und an einer Innenwand des Gehäuses ausgehend von der Einfüllöffnung eine sich in dessen Längsrichtung erstreckende Nut anzuordnen.

Figure imgaf001
An ignition transformer for a high-pressure gas discharge lamp is to be optimized for automatic production. Gas bubbles in a potting compound should be avoided. For this purpose, it is proposed to arrange a filling opening in the first side and to arrange on an inner wall of the housing, starting from the filling opening, a groove extending in its longitudinal direction.
