Abstract (en)
[origin: EP0470453A1] The ballast comprises a repetition circuit (C2, T1, T2, T3, Z1) which discharges a timing element (C1) of the ballast in the event of the lamp (1) failing to start, in order to operate the lamp (1) once again with the preheating current and to start it. The repetition circuit is deactivated by a temperature sensor (6) when the ballast reaches a predetermined limiting temperature as a result of frequent repetition. The ballast permits reliable lamp starting, to the extent that the lamp can be started, without any risk of overheating the appliance. <IMAGE>
