Title: (DE) Zuendvorrichtung für eine Entladungslampe
(EN) Ignition device for a discharge lamp
(FR) Amorceur pour lampe à décharge
Abstract: front page image
(DE) Die Erfindung betrifft eine Zündvorrichtung für eine Entladungslampe, insbesondere Hochdruckentladungslampe für Kfz-Scheinwerfer. Die, vorzugsweise als Impuls-Zündgerät ausgebildete, Zündvorrichtung ist im Lampensockel untergebracht. Sie weist erfindungsgemäß eine aus einem elektrisch leitfähigen Material bestehende, der Sockelgeometrie angepaßte Platte (1) auf, an der zumindest der Zündkondensator (C1) und die Funkenstrecke (F1) befestigt sind, wobei mindestens ein erster elektrischer Anschluß des Zündkondensators (C1) und mindestens ein erster elektrischer Anschluß der Funkenstrecke (F1) mit der Platte (1) elektrisch leitend verbunden sind.
(EN) The ignition device comprises a DC voltage input with a first and a second DC voltage terminal (j10, j11), and an ignition voltage output for the discharge lamp (LP1). The circuit includes a capacitor (C1) and an automatic switch (F1). A transformer (TR1) is provided with two parallel connected primary windings which are inductively coupled with at least one secondary winding.
