Abstract:
A low-pressure mercury vapor discharge lamp operates in either a first or a second mode of operation. The discharge lamp has a discharge vessel ( 1 ), enclosing a discharge space ( 8 ). A first end portion ( 11 ) of the discharge vessel is provided with a first electrode ( 12 ) and a first anode ( 13 ) in the vicinity of each other. A second end portion 21 of the discharge vessel is provided with a second electrode 22 and a second anode 23 in the vicinity of each other. While the discharge lamp operates in the first mode of operation, a discharge is maintained alternating between the first electrode and the second anode and between the second electrode and the first anode. While the discharge lamp operates in the second mode of operation, a discharge is maintained alternating between the first electrode and the first anode and between the second electrode and the second anode.
