SCHALTUNGSANORDNUNG ZUM ZUENDEN UND SPEISEN EINER GAS- UND/ODER DAMPFENTLADUNGSLAMPE

摘要

The invention relates to an arrangement comprising a gas and/or vapor discharge lamp (5) which includes a discharge tube (5a). An electronic auxiliary device (10-16) is arranged in parallel with the discharge lamp (5). This auxiliary device ensures that in the operating condition the lamp is shunted briefly during each half cycle of the power supply. With an arrangement according to the invention, the lamp (5) is of a type in which the discharge tube (5a) has a temperature of at least 200 DEG C. in the operating condition. The auxiliary device is connected to sensor elements (20; 25-28) which ensure that the lamp (5) is not shunted in the period of time in which the lamp (5) has not yet reached the operating condition. This achieves reliable starting of the lamp.
