Description

  

  Scheinwerfer für     Fahrzeuge,        insbesondere        Kraftfahrzeuge.       Gegenstand vorliegender Erfindung ist  ein Scheinwerfer für Fahrzeuge, insbeson  dere Kraftfahrzeuge. Dieser Scheinwerfer  ist derart eingerichtet, dass die für den Fahr  zeuglenker unangenehme und gefährliche  Blendwirkung der     ;Scheinwerfer    beim Kreu  zen von Fahrzeugen vermieden wird, ohne  dass zu diesem Zwecke die Intensität der  Beleuchtung vermindert oder besondere me  chanische     Abblendmittel        bezw.    Vorrichtun  gen, ausgelöst werden müssen.  



  Der Erfindungsgegenstand ist dadurch  gekennzeichnet, dass das Gehäuse des Schein  werfers übereinander angeordnete Licht  kanäle aufweist, welche nach vorn gegen die  Fahrbahn geneigt sind und das von der  Lichtquelle ausstrahlende Licht auf die  Fahrbahn leiten.  



  In beiliegender Zeichnung ist ein Aus  führungsbeispiel des Erfindungsgegenstan  des veranschaulicht.  



       Fig.    1 zeigt dasselbe im vertikalen Quer  schnitt, während       Fig.    2 eine Frontansicht desselben dar  stellt.    Der Scheinwerfer besitzt ein Gehäuse 1,  das nach vorn durch eine durchsichtige Glas  scheibe 2 abgeschlossen ist. Im     hintern,     durch eine Scheidewand 1' begrenzten Teil  des Gehäuses     sind    zwei elektrische     Leucht-          körper    3 angeordnet, deren jeder in einem  parabolischen Reflektor 4 sitzt, welcher die  Lichtstrahlen des     Leuchtkörpers    parallel  richtet und gegen einen ebenen Reflektor  boden 5 wirft.

   Letzterer     reflektiert    die Licht  strahlen wiederum, aber unter einem be  stimmten Winkel, so dass sie durch Licht  kanäle 6, die die Scheidewand 1' durchsetzen,  aus dem Gehäuse 1 austreten und nach vorn  schief auf die Fahrebene geleitet werden.  Zu diesem Zwecke sind die Lichtkanäle 6  nach vorn gegen die Fahrebene leicht ge  neigt und übereinander angeordnet. Die  Lichtkanäle haben schlitzförmigen     Quer-          schnitt    und werden durch quer in das Ge  häuse 1 eingebaute, in gleichmässigen Ab  ständen übereinander angeordnete, verhält  nismässig     Jünne        Zwischenwände    oder Lamel  len 7 gebildet.

   Ferner sind die Lichtkanäle  parallel zu den aus dem Gehäuse austreten  den     reflektierten    Lichtstrahlen gerichtet, wo-      bei ihre Länge und Weite so bemessen sind,  dass der Reflektor 5, der die eigentliche Ur  sache des blendenden grellen     Lichteffektes     ist, dem Lenker eines gegen den Schein  werfer sich bewegenden Fahrzeuges ver  deckt bleibt.  



  Die     Anordnung    der Lichtquelle im Ge  häuse ist     unwesentlich,    da eventuell die  Leuchtkörper 3 mit ihren entsprechenden  parabolischen Reflektoren die Stelle des Re  flektors 5     einnehmen    könnten.  



  Es sei noch bemerkt, dass der Ausdruck  "Lichtkanäle" im generellsten Sinne auszu  legen ist, das heisst auch Lichtaustritts  öffnungen oder Schlitze in sich schliesst. In  diesem Sinne könnten zum Beispiel am  Scheinwerfer zwei parallele Schlitzreihen in  einer gewissen Entfernung voneinander der  art angeordnet sein, dass die Verbindungs  linie der Mittelpunkte je zweier, einander       gegenüberliegenden    Schlitze die in bezug auf       die    Fahrebene entsprechende Neigung auf  weisen würde.



  Headlights for vehicles, in particular motor vehicles. The present invention is a headlight for vehicles, in particular motor vehicles. This headlight is set up in such a way that the dazzling effect of the headlights, which is unpleasant and dangerous for the driver, is avoided when crossing vehicles, without the intensity of the lighting being reduced for this purpose or special mechanical dimming means or. Vorrichtun conditions, must be triggered.



  The subject matter of the invention is characterized in that the housing of the headlamp has light channels arranged one above the other, which are inclined forward towards the roadway and guide the light emitted by the light source onto the roadway.



  In the accompanying drawing, an exemplary embodiment from the subject of the invention is illustrated.



       Fig. 1 shows the same in vertical cross section, while Fig. 2 is a front view of the same is. The headlight has a housing 1, which is completed by a transparent glass disc 2 to the front. In the rear part of the housing limited by a partition 1 ', two electrical luminous bodies 3 are arranged, each of which is seated in a parabolic reflector 4, which directs the light rays of the luminous body in parallel and throws it against a flat reflector base 5.

   The latter reflects the light rays in turn, but at a certain angle, so that they emerge from the housing 1 through light channels 6 that penetrate the partition 1 'and are passed forward obliquely to the driving plane. For this purpose, the light channels 6 are slightly inclined forward against the driving plane and arranged one above the other. The light channels have a slit-shaped cross-section and are formed by relatively thin partition walls or slats 7 built across the housing 1 and arranged at regular intervals on top of one another.

   Furthermore, the light channels are directed parallel to the reflected light rays emerging from the housing, their length and width being dimensioned so that the reflector 5, which is the actual cause of the blinding glaring light effect, is the handlebars of a headlamp moving vehicle remains covered.



  The arrangement of the light source in the housing Ge is insignificant, since the luminous bodies 3 with their corresponding parabolic reflectors could take the place of the reflector 5 Re.



  It should also be noted that the expression “light channels” is to be interpreted in the most general sense, that is to say it also includes light exit openings or slits. In this sense, for example, two parallel rows of slots could be arranged on the headlight at a certain distance from each other such that the connecting line of the center points of two opposing slots would have the corresponding inclination with respect to the driving plane.
