Description
"ßlendungsfreier Scheinwerfer" Die Erfindung betrifft einen blendungsfreien Scheinwerfer, insbesondere für Kraftwagen."Glare-free headlight" The invention relates to a glare-free headlight Headlights, in particular for motor vehicles.
Der ..Scheinwerfer nach der 2rfindung ist gekennzeichnet durch mehrere, in einer um 450 gegen die Lichtstrahlen geneigten Linie hintereinander angeordnete, die Lichtstrahlen um 000 ablenkende :Spiegel und an die bpiegel anschließende Kammern mit beidseitig im Zick-Zack geführten @iänden.The .. headlight according to the 2rfindung is characterized by several, arranged one behind the other in a line inclined by 450 against the light rays, deflecting the light rays by 000 : mirrors and chambers adjoining the mirror with zigzag lines on both sides.
In Breiterer 'Lusbildung der Erfindung sind die Bände jalousiea.rtig
ausp.ebildet.
In der Ochnittkante der beiden rrism.en, die unter 45o gegen die Lichtstrahlen geneigt ist, sind hintereinander Spiegel 3 angeordnet, welche die Lichtstrahlen um 90o ablenken. Die Spiegel nehmen die ganze Höhe des Gehäuses ein und sind so breit, daß ein an der Kante eines Spiegels 3 vorbeistreichender Lichtstrahl auf den nächsten Spiegel 3 trifft. :Dadurch werden alle von der Lichtquelle 2 ausgehenden Strahlen um 90o gegen die ursprüngliche Richtung abgelenkt.In the Ochnittkante the two rrism.en, which under 45o against the light rays is inclined, mirrors 3 are arranged one behind the other, which the light rays distract 90o. The mirrors take up the entire height of the case and are like that wide that a light beam sweeping past the edge of a mirror 3 hits the next mirror 3. : This will all emanating from the light source 2 Beams deflected 90o against the original direction.
Von den Spiegeln 3 Werden die Strahlen durch Kammern gelenkt, deren , -ände 4,5, entweder im Zick-Zack verlaufen oder jalöusieartig gestaltet sind.From the mirrors 3 the rays are directed through chambers, whose , -ands 4,5, either run in zigzag or are designed like blinds.
Zweckmäßig ist der abstand a der Jände 4,5, einer Kammer gleich der rrojektion der Breite eines Spiegels 3 auf den Querschnitt einer -2'#l-aramer; die Länge c einer Kammer ist zweckmäßig ein Mehrfaches der Breite a.Appropriately, the distance a of the Jands 4.5, a chamber is equal to rprojection of the width of a mirror 3 onto the cross section of a -2 '# l-aramer; the The length c of a chamber is expediently a multiple of the width a.
Durch die Ausbildung der "Fände treten nur die paralell zu den 0länden gerichteten Lichtstrahlen aus den Jammern aus. Alle davon abweichenden --strahlen werden von den Jänden absorbiert, wenn diese aus einem *:er'e-stoff hergestellt sind, der lein Licht reflektiert.Because of the formation of the "finds, only those appear parallel to the 0lands directed rays of light out of the whines. All deviating - rays are absorbed by the walls if they are made of a *: er'e-material that reflect no light.
Sind nun die austretenden Lichtstrahlen paralell zur Fahrtrichtung
eines Eraftfahrzeuges gerichtet, dann können sie die Fahrer entgegenkommender r'ahrzeuge
nicht treffen. selbst wenn dieser in den Scheinwerfer hineinschaut, blickt er auf
die dunklen bände, so daß er nicht geblendet wird. ' Diese. iiirkung kann noch dadurch
verbessert werden, d.aß die austretenden Lichtstrahlen leicht durch eine entsprechende
