ANORDNUNG ZUM STARTEN UND BETREIBEN VON LEUCHTSTOFFLAMPEN

摘要

In the case of operating circuits, which have no starter and operate with a high-reactance transformer (3) and an invertor (2), for fluorescent lamps (5) cold starts frequently occur particularly at relatively high environmental temperatures, which cold starts greatly reduce the life of the fluorescent lamps if they occur frequently. In order to prevent this, the starting voltage is switched on delayed with respect to the heating voltage for the incandescent cathodes (51, 52), for example by means of a triac (62). <IMAGE>
