Description

Gegenstand der vorliegenden Erfindung ist ein Schein-,verfer finit parabolischem Reflektor, insbesondere für Kraftfahrzeuge, mit welchem eine gleichinüßige Zerstreuung des Lichtes erzielt wird, die jede .\rt Blendwirkung ausschaltet, ohne daß eitle wesentliche Abschwächung der Lichtstärke eintritt. 1)al>ei wird ein schattenloses, gleichmäßiges Licht gegebelt, welches ähnlich dein Mondlicht auf das _\uge wohltuend wirkt, da es nicht blendet. Beim Hineinschauen in das Licht wird (las Auge nicht unwillkürlich zum Schließen veranlaßt. Aus dieseln Grunde braucht all (lern Scheinwerfer keine .\1>-blendeinrichtung vorgesehen werden.The present invention is a sham, verfer finite parabolic reflector, in particular for motor vehicles, with which an equal Diffusion of light is achieved, which eliminates any glare without that there is a vain essential weakening of the light intensity. 1) al> egg becomes a shadowless, uniform light, which is similar to your moonlight on the _ \ uge soothing works because it doesn't dazzle. When looking into the light, (eye did not read involuntarily caused to close. For these reasons, all (learn headlights no. \ 1> masking device should be provided.

1)as Wesen der Erfindung bestellt darin. (laß zwischen t,ichtquelle und Scheinwerferscheibe eine matte lichtdurchlässige Wand, insbesondere weißes Textilgewebe, angeordnet ist, welche senkrecht und rechtwinklig zur Hauptachse des Reflektors gerichtet ist, und (laß die Scheinwerferscheibe außerdem mit irgendeinem farbigen Belag versehen sviti kann.1) The essence of the invention orders therein. (leave between t, source of light and headlight disc a matt translucent wall, in particular white textile fabric, is arranged, which is perpendicular and at right angles to the main axis of the reflector is directed, and (also leave the headlight lens with some colored Covering provided sviti can.

I )ie Zeichnung veranschaulicht den l:rfiitdungsgegeirstand in einer beispielsweisen Ausführungsform; es -zeigt die Figur eineu Schnitt durch einett Scheinwerfer finit parabolischem Reflektor in der l,üngsrichtttn g.I) the drawing illustrates the object of the invention in an exemplary embodiment; The figure shows a section through a headlight finite parabolic reflector in the longitudinal direction.

\\'ie die Figur -zeigt, ist zwischen Lichtquelle r und der Scheinwerferscheibe 2 eitle lichtdurchlässige, weiße Wand 3 angebracht. Dieselbe steht senkrecht und rechtwinklig zur Hauptachse des Reflektors. Genannte Wand ist aus feinem Textilgewebe (hauchdünn) hergestellt und hat gegenübler (len Lichtstrahlen folgende Eigenschaften: r. läßt sie die zur Hauptachse des Reflektor. parallel verlaufenden Lichtstrahlen durch, wobei eine Zerstreuung derselben infolge der feinen Poren im Geivebe verursacht wird: 2. läßt sie eine mehrfache I )ifftisionserscheinung zu, indem die auf die Leinwand auftreffenden Strahlen teilweise zurückstrahlen und vom lZeflektor in allen Richtungen wiederum zurückgestrahlt werden.\\ 'ie the figure shows is between the light source r and the headlamp lens 2 vain translucent, white wall 3 attached. The same is vertical and perpendicular to the main axis of the reflector. Said wall is made of fine textile fabric (wafer-thin) and has the following properties compared to (len light rays): r. leaves them to the main axis of the reflector. parallel rays of light by causing a scattering of the same due to the fine pores in the Geivebe will: 2. it allows a multiple I) ifftision phenomenon by the Rays incident on the canvas partially reflect back and from the lZeflektor in all Directions are reflected back.

Genannte Eigenschaften der weißen Wand können noch erlrciht bzw. durch eine «eitere (zusätzliche) ergänzt werden, wenn die Farbe der Zwischenwand geändert wird, so daß dieselbe ermöglicht, gewisse farbige Strahlen zu absorbieren. Wie (lern auch sei. durch die Punkte r und 2 wird infolge der tittelldlich Vielen Strahlen, ihrer Brechungen und Riickstrahlwirkungen eine derart feine Zerstreuung des Lichtes erzielt, daß es vollständig schattenlos wirkt. I)er erzielte Lichtschein ist identisch mit demjenigen (fies diffusen Mondlichtes, so daß ein Hineinsehen in den Scheinwerfer das Auge nicht stört. Dabei wird ein bedeutend breiteres, gleichmäßig leuchtendes Gesichtsfeld gegeben, welches den Fahrer jeden Fremdkörper auf der Fahrbahn wahrnehmen läßt.Mentioned properties of the white wall can still be achieved or through an «extra (additional) can be added if the color of the partition wall is changed so that it enables certain colored rays to be absorbed. How (learn also be. through the points r and 2, as a result of the tittelldlich many rays, Their refractions and retroreflective effects result in such a fine dispersion of light achieved that it appears completely shadowless. I) he achieved glow is identical with the one (nasty diffuse moonlight, so that one looks into the headlights does not bother the eye. This creates a significantly wider, evenly luminous one Given the field of vision, which the driver can perceive every foreign object on the road leaves.

In der Figur sind zwei verschiedene Strahlen eingezeichnet, welche von der Lichtquelle ausgehen. Letztere liegt int l@rennpunlct: infolgedessen \-erläuft der von der Lanilw i direkt zuiu 12eHel;tor 6 kom- mende und \,on dort nach atillen getV<irfene Strahl .1 parallel zur Hauptachse des letzteren lies zur \Vand3, von welcher er gebrochen (lunch (lie Sclteilie 2 tritt und alt dieser nochmals gebrochen wird.
