Es ist auch möglich, Glühwendeln vertikal anzu­ ordnen und/oder diese mit horizontalen Glühwendeln zu kombinie­ ren. Jede Glühwendel kann einzeln geschaltet werden, so daß durch die Auswahl der jeweiligen Glühwendel oder durch entspre­ chende Kombination von Glühwendeln eine bestimmte Ausrichtung des Lichtstrahls erreicht werden kann, da jede Glühwendel mit ihrem Reflektors bzw. der Blende anders im Raum ausgerichtet ist. Zur Ansteuerung der Glühwendeln verfügt die Beleuchtungs­ einrichtung über eine geeignete Steuereinrichtung.For this purpose, a lighting device is provided according to the invention tion to create that has incandescent lamps that have at least two Have filaments that are horizontal, i.e. H. side by side are arranged, each filament having its own reflector has or with an aperture between the filaments is arranged. It is also possible to turn on incandescent filaments vertically arrange and / or combine these with horizontal filaments ren. Each filament can be switched individually, so that by selecting the respective filament or by corresponding appropriate combination of incandescent filaments a certain orientation of the light beam can be achieved because every filament with your reflector or the aperture aligned differently in the room is. The lighting is used to control the filaments device via a suitable control device.

Bevorzugterweise ist die Steuereinrichtung mit Sensoren ausge­ stattet, die entgegenkommende Fahrzeuge registrieren, so daß automatisch die blendfreie Ausrichtung des Lichtstrahls vorge­ nommen wird.The control device is preferably equipped with sensors the oncoming vehicles register so that automatically pre-glare-free alignment of the light beam is taken.

Die Glühlampe 10 nach Fig. 1 besitzt zwei Glühwendeln 11, 12, die eine unterschiedliche räumliche Ausrichtung haben. Beide Glühwendeln 11, 12 sind durch eine Blende 13 voneinander abge­ schirmt, so daß sich deren Lichtkegel nicht überschneiden. Der Sockel 14 der Glühlampe 10 verfügt zum Anschluß über übliche Steckkontakte 15. Hingegen weisen die drei Glühwendeln 16, 17, 18 der Glühlampe 19 nach Fig. 2 Reflektoren auf 20, 21, 22, wo­ bei auch hier die Ausrichtung der Lichtkegel voneinander abwei­ chend ist. Die Steckkontakte 23 sind im Inneren des Sockels 24 mittels eines Kommutators 25 oder nach einer anderen Variante sind die Steckkontakte 23, wie in Fig. 1 direkt mit den Glüh­ wendeln 16, 17, 18 verbunden. In der Aufsicht nach Fig. 3 ist ersichtlich, wie eine Blendung des Gegenverkehrs ausgeschlossen wird. Üblicherweise würde das Fahrzeug 29, das eine Rechtskurve fährt, das entgegenkommende Fahrzeug 30 blenden. Über Sensoren der Beleuchtungseinrichtung wird das entgegenkommende Fahrzeug 27 registriert und durch entsprechende Schaltung der Glühwen­ deln 11, 12, 16, 17, 18 eine Blendung vermieden. Außerdem leuchtet der Lichtkegel 34, der etwas nach rechts gedreht wird, und der Lichtkegel 33, der etwas nach links gedreht wird, die Fahrbahnränder 31 und 32 gut aus. Die Steuerschaltung kann auch mit der Lenkung verbunden sein, so daß automatisch der Lichtkegel dem Richtungswechsel angepaßt wird. Fig. 3 zeigt ei­ ne horizontale Anordnung von drei Scheinwerfern 26, 27, 28 zur Ausbildung der erfindungsgemäßen Beleuchtungseinrichtung, die in der gleichen Weise wie die Glühwendeln 11, 12, 16, 17, 18 eingesetzt werden. In Fig. 5 ist schematisch ein Scheinwerfer 36 dargestellt, der in seinem Inneren über zwei Glühlampen 38, 39 verfügt, die durch eine Blende 37 voneinander abgeschirmt sind. The incandescent lamp 10 of FIG. 1 has two filaments 11, 12 that have a different spatial orientation. Both incandescent filaments 11 , 12 are shielded from one another by an aperture 13 , so that their light cones do not overlap. The base 14 of the incandescent lamp 10 has conventional plug contacts 15 for connection. On the other hand, the three filaments 16 , 17 , 18 of the incandescent lamp 19 according to FIG. 2 reflectors 20, 21, 22, where the alignment of the light cone is also different here. The plug contacts 23 are inside the base 24 by means of a commutator 25 or according to another variant, the plug contacts 23 , as in FIG. 1, directly connected to the glow filaments 16 , 17 , 18 . The supervision according to FIG. 3 shows how dazzling oncoming traffic is excluded. Typically, the vehicle 29 that is turning right would blind the oncoming vehicle 30 . The oncoming vehicle 27 is registered via sensors of the lighting device and glare is avoided by appropriate switching of the bulbs 11 , 12 , 16 , 17 , 18 . In addition, the light cone 34 , which is rotated somewhat to the right, and the light cone 33 , which is rotated somewhat to the left, illuminates the road edges 31 and 32 well. The control circuit can also be connected to the steering so that the light cone is automatically adapted to the change of direction. Fig. 3 shows ei ne horizontal arrangement of three headlights 26 , 27 , 28 to form the lighting device according to the invention, which are used in the same way as the filaments 11 , 12 , 16 , 17 , 18 . A headlight 36 is shown schematically in FIG. 5, which has two light bulbs 38 , 39 in its interior, which are shielded from one another by an aperture 37 .
