Description

Wenn ein .-\uto mit voll aufgeblendeten Scheinwerfern vorbeifährt, so wird man schon in einer l?ntfernutlg voii etwa 200M seitlich erheblich gelilendet; die Blendwirkung verstärkt sich 'beim Herannahen und wird am stärksten beim Vorbeifahren, weil beim parabolischen Scheinwerfer auf kurze Entfernung die Lichtstrahlen rechtwinklig reflektiert werden und wie ein Spiegel wirken. Man hat dann, besonders hei den modernen. mit senkrechten Rillen versehenen Scheiben den Eindruck. als ob der Glühfaden seitlich verschoben ist und die l?mpfindung, als ob man von der ganzen Lampe direkt ins Gesicht gestrahlt wird.When a .- \ uto drives by with the headlights fully on, in this way one is already considerably lilted sideways in a distance of about 200M; the dazzling effect increases when approaching and is strongest when driving past, because with parabolic headlights the light rays are right-angled at a short distance be reflected and act like a mirror. You have then, especially in the modern one. discs with vertical grooves give the impression. as if the filament is sideways is shifted and the sensation as if one of the whole lamp directly in the face is blasted.

Doch ist das eine Art optischer Täuschung.But that's a kind of optical illusion.

Die 131et13w-irkung wird nur von einem schmalen Streiten hervorgerufen, der je nach der Größe des Glühfadens bei der Autolampe in etwa 2 bis 3 cm Breite waagerecht, etwa in der Mitte ringsherum, über Scheinwerfer und Scheibe verläuft.The 131et13w effect is only caused by a narrow argument, depending on the size of the filament on the car lamp, about 2 to 3 cm wide runs horizontally, around the middle, over the headlights and windshield.

Setzt inan in dieseru Streifen die Reflektierung I1eral). so ist die seitliche Blendung auf Stadtlicht gedämpft. Die Erfindung bezweckt also, daß die die .\tigen treffenden Strahlen in einem Streifen, der etwa So cm breit ungefähr, in einer Höhe von r,4o bis 2.20 111 waagerecht über den Erdboden verläuft, nicht blenden können und diese Strahlen auf Stadtlicht gedämpft werden.In this stripe, add the reflection I1eral). so the side glare on city light is reduced. The aim of the invention is to ensure that the rays hitting the ground in a strip that is about so cm wide, at a height of r.4o to 2.20 111 horizontally above the ground, cannot dazzle and these rays are attenuated to city light .

I:rfindtingsgemäß sind Mittel zum Abblenden der Lichtstrahlen des Scheinwerfers im Bereich eines waagerechten, schmalen, durch die Mitte des Schein-%\erferkegels hindurchlaufenden Streifens vorgesehen.According to the invention, means for masking the light rays of the Headlights in the area of a horizontal, narrow, through the middle of the light cone continuous strip provided.

\-lan kann zu diesem "!.weck i. die Glithbirne des Scheinwerfers mit einem waagerechten, schmalen, etwa 3 bis d'mm breiten dunklen Streifen versehen, der quer durch die @-titte der Glashülle verläuft. =. den Reflektor im Bereich eines schmalen.-quer über die'titte desReflektors verlaufenden Streifens mattieren. 3. die den Scheinwerfer abdeckende Glasscheibe mit einem schmalen, waagerechten, über die Scheibenmitte verlaufenden dunklen oder mattierten Streifen versehen.\ -lan can for this "!. wake up i. the glithbulb of the headlight with provided with a horizontal, narrow, about 3 to d'mm wide dark stripe, which runs right through the middle of the glass envelope. =. the reflector in the area of a matt a narrow strip running across the middle of the reflector. 3. the glass covering the headlight with a narrow, horizontal, over provide dark or matt stripes running down the middle of the pane.

l)ie Erfindung ist nicht auf die dargestellte Ausführungsform beschränkt. Es -können vielmehr die Streifen, je nach Art der Lampen- oder Scheinwerferkonstruktionen, schmaler und breiter, auch in der '-litte gegenüber der Birne mit unterschiedlichen '!aßen zur Anwendung gelangen. ebenso Kann die Abblendung durch Vorrichtungen, die die waagerechten, mittleren Abblendungsstreifen ersetzen,erreicht werden,ohne daß damit derRahmen der Erfindung überschritten wird. l>ie 7eichnun;;; veranschaulicht 1>eishiel:@reise schematisch den 1?rhndungsgegenstand und die durch ihn erreichte _@hhlendung, wobei _@hl>. .'-\ die scheinbare :e:tlic're Verschiebung des Leuchtfadens und die volle 131en(Iting der Augen angibt; a) zeigt dabei die Scheil7e mit Reflektor; b) und !r1) sind die Strahlen. die nicht blenden; c) ist der Raum der voll blendenden Strahlen und zeigt die Höhe der Blendwirkung, (1) auf den Fußgänger, e) auf den Radfahrer, f) auf den PKW, g) auf den LKW: -Sb. 13 zeigt den die .\tigen blendenden Streifen im Scheinwerfer; Abb.

Rather, the strips, depending on the type of lamp or headlight construction, narrower and wider, and also in the middle compared to the pear with different "! Ate" can be used. Likewise, the screening can be achieved by devices which replace the horizontal, central screening strips, without thereby going beyond the scope of the invention. l> ie 7eichnun ;;; illustrates 1> eishiel: @travel schematically the subject of the invention and the _ @ hhlendung achieved through him, whereby _ @ hl>. .'- \ the apparent: e: tlic're shifting the Filament and the full 131en (iting of the eyes indicates; a) shows the Scheil7e with reflector; b) and! r1) are the rays. which do not dazzle; c) is the space of fully blinding rays and shows the level of glare, (1 ) on the Pedestrians, e) the cyclist, f) the car, g) on the truck: -Sb. 13 shows the dazzling stripes in the headlight; Fig. C: shows the strip blinding the eyes on the glass panel and Fig. 1) the strip that dazzles der (@liihl) irne, a) from previous, b) from the side; Ahb.
