This measure also serves, in particular, to have a substantially parabolic design and to consolidate the seat of the lamp in the reflector according to the invention, according to certain spatial design features. If the melting tips protrude in depressions, not in the upper part of a reflector 1, a depression 3 is more likely to protrude from the reflector, as this means that the lamps are only held by a press fit at the 15 for receiving a melting tip 4 of a lightning bolt upper end. lamp 2 on.
