操作能被插入电路装置中的至少第一和第二灯的电路装置
摘要：
本发明涉及操作至少第一和第二灯的电路装置，所述灯能被插入到所述电路装置中，每个灯具有第一和第二灯丝，所述电路装置具有一驱动电路以驱动所述至少第一和第二灯，所述驱动电路被设计成用射频信号操作所述至少第一和第二灯，该电路装置还包括：比较电路，用于比较该电路装置内的第一和第二电压电势；以及去活装置，用于去活所述驱动电路，其中所述比较电路被设计用来在所述至少第一和第二灯利用射频信号操作期间，当所述第一和第二电压电势之差超过预定极限值时激活所述去活装置。
摘要（英）：

A circuit arrangement for operating at least one first and one second lamp which can be inserted in the circuit arrangement, each lamp having a first and a second filament, having a drive circuit for the purpose of driving the at least one first and second lamp, the drive circuit being designed to operate the at least one first and second lamp using a radiofrequency signal, it also includes: a comparator circuit for comparing a first and a second voltage potential within the circuit arrangement, and a deactivation apparatus for deactivating the drive circuit, the comparator circuit being designed to activate the deactivation apparatus if the difference between the first and the second voltage potential exceeds a predeterminable limit value during operation of the at least one first and one second lamp using a radiofrequency signal.
