Description

Abblendvorrichtung für Fahrzeugscheinwerfer Bei Abblendvorrichtungen für Fahrzeugscheinwerfer ist es bekannt, oberhalb des abzublendenden Scheinwerfers einen undurchsichtigen Schirm anzuordnen, dessen Länge wenigstens gleich dein Durchmesser der Scheinwerferöffnung ist, und der mit dein Scheinwerfer oder unabhängig davon durch ein z. B. vom Führersitz aus zu betätigendes Zugmittel so nach vorn gekippt werden kann, daß sein vorderes Ende den Strahlenkegel abblendet. Vorzugsweise wird die Einrichtung so getroffen, daß der Schirm nur den oberen Teil des Strahlenkegels abblendet und zur Abblendung des unteren Teiles des Strahlenkegels eine feste Abblendevorrichtung benutzt wird, z. B. durch Schwärzen des unteren Teiles des Deckglases des . Scheinwerfers. Wird ein solcher Schirm in Abblendstellung gebracht, so kann je nach Platz und Art der Anbringung des Schirmes am Scheinwerfer entweder gar kein Licht aus dem Scheinwerfer treten, so daß die Fahrbahn auch in der Nähe des Fahrzeuges völlig unbeleuchtet bleibt, oder der Lichtkegel fällt so dicht vor dem Fahrzeug auf die Fahrbahn, daß von einer Nahbeleuchtung der letzteren ebenfalls nicht die Rede sein kann.Dimming device for vehicle headlights For dimming devices for vehicle headlights, it is known above the headlight to be dimmed to arrange an opaque screen, the length of which is at least equal to your diameter the headlight opening, and the one with your headlight or independently of it by a z. B. from the driver's seat to be actuated traction means so tilted forward can be that its front end dims the beam cone. Preferably will the device is made in such a way that the screen only covers the upper part of the cone of rays and a fixed masking device for masking the lower part of the beam cone is used, e.g. B. by blackening the lower part of the cover slip of the. Headlights. If such a screen is placed in the dipped position, depending on the space and type attaching the screen to the headlight either no light at all from the headlight step so that the road is completely unlit near the vehicle remains, or the cone of light falls so close in front of the vehicle on the road that there can also be no question of a close-up illumination of the latter.

Um bei völliger Abdeckung des nach vorn gerichteten, blendenden Lichtes doch eine ausreichende Nahbeleuchtung beibehalten zu können, wird nach der Erfindung der Abblendschirm einer bekannten Abblendvorrichtung der eingangs beschriebenen Art konkav nach Oben durchgebogen. Um die Nahbeleuchtung noch zu verstärken, kann die der Lichtquelle zugekehrte Unterseite des Abblendschirmes weiterhin in an sich bekannter Weise verspiegelt sein.To with complete coverage of the blinding light directed forward but being able to maintain sufficient close-range lighting is according to the invention the dimming screen of a known dimming device of the type described above Art concave curved upwards. In order to intensify the close-up lighting, you can the underside of the anti-glare screen facing the light source continues in itself be mirrored as is known.

Die damit zu erreichende Nahbeleuchtung macht für den Fahrer nicht nur den nächsten Teil der Fahrbahn erkennbar, sondern erhellt die Straße auch nach den Seiten hin, so daß Wegweiser, Fahrzeichen u. dgl. angeleuchtet werden und insbesondere auch für die Insassen entgegenkommender, schlecht beleuchteter Fahrzeuge über die seitliche Ausdehnung des «den oder die Scheinwerfer tragenden Fahrzeuges kein Zweifel entstehen kann.The close-range lighting that can be achieved with it does not do anything for the driver only the next part of the lane can be seen, but also illuminates the road the sides so that signposts, signs and the like are illuminated and in particular also for the occupants of oncoming, poorly lit vehicles via the Lateral expansion of the vehicle carrying the headlight (s) no doubt can arise.

Durch -die Maßnähme nach der Erfindung wird also für- das Fahren mit abgeblendeter Scheinwerferbeleuchtung eine wesentlich größere Sicherheit geschaffen als es ohne seitliche Nahbeleuchtung möglich ist.By -the measure according to the invention is therefore for- driving with dimmed headlight lighting created a much greater security than is possible without lateral close-up lighting.
