Beschreibung
Zusammenfassung:	A system for driving a plurality of lamps comprises a lamp module, an inverter circuit providing currents to the lamp module, an interface for conveying the currents, a splitter, a balance unit, and a fault detecting circuit. The splitter receives the currents provided by the inverter circuit through the interface and distributing the currents to the plurality of lamps. The balance unit balances the currents provided to the plurality of lamps in the lamp module. The fault detecting circuit detects and reports a condition of at least one of the lamps by detecting signals generated from the inverter circuit. The fault detecting circuit receives the signal from a point in the system, such that the fault detecting circuit can detects the signals before the signal undergoes the distributing by the splitter.
