Description

  

  Beleuchtungsanlage an Fahrzeugen.    Bei der Verwendung von Scheinwerfern  an Fahrzeugen erfordert die Verkehrssicher  heit, dass diese nötigenfalls abgeblendet sind.  Die Abblendung erfolgt in bekannter Weise  durch Einschaltung einer schwächeren Licht  quelle. Dadurch wird die Sichtweite beträcht  lich verkürzt. Ein weiterer Nachteil besteht  darin, dass diese schwächere Lichtquelle auch  weiterhin sichtbar bleibt, wodurch die Blen  dung nur vermindert, aber nicht verhindert  wird.  



  Gegenstand der Erfindung ist eine Be  leuchtungsanlage an Fahrzeugen, gekenn  zeichnet durch mindestens einen Scheinwer  fer mit einem     trichterähnlichen    Gehäuse, des  sen Tiefe mindestens zweieinhalbmal so gross  ist als der mittlere Durchmesser der vordern  Öffnung des Gehäuses, welches Gehäuse den  Lichtkegel begrenzt und nach schräg unten  gerichtet ist, das Ganze derart, dass die Licht  quelle entgegenkommenden Strassenbenützern  unsichtbar ist.  



  Auf beiliegender Zeichnung ist unter       Fig.    1 ein Ausführungsbeispiel des Erfin  dungsgegenstandes dargestellt. Auf dem Vor  derteil eines Fahrzeuges sind vier Scheinwer  fer angebracht. 1 und 2 zeigen Scheinwerfer  bekannter Ausführung, während bei den  Scheinwerfern 3 und 4 die Lichtquelle 5 je  am hintern Ende eines     trichterähnlichen    Ge  häuses 6 eingesetzt ist. Das Gehäuse 6 hat  eine Tiefe, die mindestens zweieinhalbmal so  gross ist als der mittlere Durchmesser der     vor-          dern    Öffnung des Gehäuses.

   Unter dem mitt-         leren    Durchmesser ist das arithmetische Mit  tel von grösstem und kleinstem Durchmesser  der Öffnung zu verstehen, falls die Öffnung  nicht wie im gezeichneten Fall     kreisrund,    son  dern zum Beispiel oval oder vieleckig ist. Für  die gezeichnete kreisförmige Öffnung ist so  mit der mittlere Durchmesser gleich dem  Kreisdurchmesser. Die Gehäuse 3 und 4 sind,  wie     Fig.    1 zeigt, so am Fahrzeug angebracht,       class    der Lichtkegel nach schräg unten gerich  tet und die Lichtquelle entgegenkommenden  Strassenbenützern, z. B. Fussgängern oder  Lenkern von Fahrzeugen, unsichtbar ist. Die       trichterähnlichen    Gehäuse können in die Kot  flügel eingebaut sein.

   Zur Vermeidung des       Eindringens    von Schmutz kann die Öffnung  des Gehäuses mit einer Schutzscheibe aus Glas  oder anderem durchsichtigem Material ver  sehen werden. Bei der Fahrt auf freier Strasse  können zweckmässig die voll sichtbaren Schein  werfer 1 und 2 eingeschaltet werden. Kom  men jedoch andere Strassenbenützer dem  Fahrzeug entgegen, so können die Scheinwer  fer 1 und 2 ausgeschaltet und die Scheinwer  fer 3 und 4 in Funktion gesetzt werden,  deren Lichtkegel durch das     trichterähnliche     Gehäuse derart begrenzt ist, dass der Licht  kegel die Fahrbahn aufhellt, ohne dass ent  gegenkommende Strassenbenützer die Licht  quelle erblicken und von ihr geblendet wer  den können.

   Eine Verminderung der Licht  stärke dieser Scheinwerfer 3 und 4 zur Ver  meidung des     Blendens    ist dann nicht mehr  nötig, so dass die Reichweite der Beleuchtung      während des     Kreuzens    mit andern Strassen  benützern nicht oder nur     unwesentlich    ver  mindert wird.



  Lighting system on vehicles. When using headlights on vehicles, traffic safety requires that they are dimmed if necessary. The dimming is done in a known manner by switching on a weaker light source. This shortens the range of vision considerably. Another disadvantage is that this weaker light source remains visible, which only reduces glare, but does not prevent it.



  The invention is a Be lighting system on vehicles, characterized by at least one headlight fer with a funnel-like housing, the depth of which is at least two and a half times as large as the mean diameter of the front opening of the housing, which housing limits the light cone and directed obliquely downwards The whole thing is such that the light source is invisible to oncoming road users.



  In the accompanying drawing, an embodiment of the invention is shown in Fig. 1. On the front part of a vehicle four headlights are attached fer. 1 and 2 show headlights of a known design, while the headlights 3 and 4, the light source 5 is used at the rear end of a funnel-like housing 6 Ge. The housing 6 has a depth which is at least two and a half times as great as the mean diameter of the front opening of the housing.

   The mean diameter is to be understood as the arithmetic mean of the largest and smallest diameter of the opening, if the opening is not circular, as in the case shown, but is, for example, oval or polygonal. For the drawn circular opening, the mean diameter is the same as the circle diameter. The housing 3 and 4 are, as Fig. 1 shows, so attached to the vehicle, class the light cone down obliquely tet and the light source oncoming road users, z. B. pedestrians or drivers of vehicles, is invisible. The funnel-like housing can be built into the fender.

   To avoid the ingress of dirt, the opening of the housing can be seen ver with a protective pane made of glass or other transparent material. When driving on the open road, the fully visible headlights 1 and 2 can be switched on. If, however, other road users come towards the vehicle, the headlights 1 and 2 can be switched off and the headlights 3 and 4 activated, the cone of light of which is limited by the funnel-like housing in such a way that the cone of light illuminates the roadway without oncoming road users can see the source of light and be blinded by it.

   A reduction in the light intensity of these headlights 3 and 4 to avoid dazzling is then no longer necessary, so that the range of the lighting is not reduced or is only insignificantly reduced for users when crossing other roads.
