Abstract (en)
[origin: EP2375868A2] The ballast (1) has an interface device (50) comprising a signal path i.e. input port (51), to guide brightness control information, which is assigned to external digital control signals, to an input port (31) of a microcontroller (30). The interface device comprises a Zener diode to detect a control signal structure of the control signals and for opening a signal path, which is assigned to the detected signal structure, and/or to block the signal path, which is not assigned to the detected signal structure. An enhancement-type transistor of the signal paths is controlled by the signals. An independent claim is also included for a method for operating an electronic ballast for driving a lamp.
