Abstract:
1. A rod-shaped retrofit lamp for replacing a fluorescent lamp, having an end face from which two pins project, with the two pins being connected to an internal electronics unit located in the lamp via a respective current path extending between the respective pin and the lamp's electronics unit, wherein the retrofit lamp furthermore has a mechanical sensing unit, and the respective current path has a plurality of electrically conductive sub-segments of which a first sub-segment is electrically connected to the associated pin and of which a second sub-segment is electrically connected to the lamp's electronics unit, wherein the mechanical sensing unit is capable of being elastically pushed in counter to its projection direction from a released condition into an engaged condition and interacting with the two current paths in such a way that the respective current path's first and second sub-segment will have been galvanically mutually coupled when the sensing unit is in the engaged condition so that the respective current path will have been closed and the associated pin thereby electrically connected to the internal electronics unit, whereas when the sensing unit is in the released condition the respective current path's first sub-segment will have been galvanically decoupled from the respective current path's second sub-segment so that the respective current path will have been interrupted and the associated pin thereby galvanically decoupled from the lamp's electronics unit, wherein the sensing unit for galvanically separating the two pins and hence for protecting users from shock hazards is taken from its released to its engaged condition in order to couple the lamp's internal electronics unit to the supply voltage only when the retrofit lamp has been completely fitted into a luminaire.
