Abstract

Die Erfindung betrifft ein neues Vorschaltgerät für eine Entladungslampe, bei dem eine Dauerbetriebs-Regelschaltung dann außer Funktion gesetzt wird, wenn ein eine Vorheizzeit definierender physikalischer Vorgang eines Vorheizzeitgliedes noch nicht ausreichend zurückgelaufen ist, wenn die Lampe wieder neu gestartet werden soll.

Figure imgaf001
The invention relates to a new ballast for a discharge lamp, in which a continuous operation control circuit is then disabled when a preheating defining a preheating time of a Vorheizzeitgliedes has not sufficiently run back when the lamp is to be restarted.
