Description
Scheinwerfer Die Erfindung .betrifft Blendschutzeinrichtttngen. insbesondere an Fahrzeugscheinwerfern, und bezweckt, diese möglichst .einwach und wirksam zu gestalten. Bekanntlich bilden Fahrzeugscheinwerfer, besonders von Kraftfahrzeugen. mrit starkkerzigen Lampen ttn#1 Reflektoren, wegen ihrer Blendwirkung oft eine Gefahrenquelle. Es wurde deshalb vorgeschlagen, derartige Scheinwerfer .mit Einrichtungen zu versehen, die das Licht vermindern oder abschatten, ganz löschen oder es von seiner .Richtung ablenken können. Derartige Vorrichtungen erfordern aber für den Augenblick die volle Aufmerksamkeit des Wagenlenkers, und zwar gerade zu einer Zeit, wenn die Aufmerksamkeit zum Steuern des Wagens erforderlich wird. Außerdem übt die plötzliche Änderung der Lichtstärke auch auf den Fahrer eine vorübergehende Blendwirkung ,aus.Headlights The invention relates to anti-glare devices. in particular on vehicle headlights, and aims to make them as responsive and effective as possible design. As is known, form vehicle headlights, especially of motor vehicles. With strong candlestick lamps ttn # 1 reflectors, often a source of danger because of their glare effect. It has therefore been proposed to provide such headlights with devices which diminish or shade the light, extinguish it entirely or move it from its direction can distract. Such devices require the full for the moment Attention of the charioteer, especially at a time when the attention is required to control the car. It also exercises the sudden change in Light intensity also has a temporary glare effect on the driver.
Die Einrichtung nach der Erfindung soll dagegen ständig in Wirksamkeit sein und einen ausreichenden Blendschutz gewähren, also keine Handhabung oder Tätigkeit von seiten des Wagenlenkers erfordern. Dies wird nach der Erfindung erreicht, indem vor rl:ie Vorderseite der Lampe eine klare, durchsichtige Linse, durch die bestimmte Strahlen der Lichtquelle hindurchtreten können, gesetzt wird und außerdem zwischen der Licht-. -:, . quelle und dem Reflektor eine durchscheinende oder h.albdurchs,ichtige Umhüllung vorgesehen wird, durch die die übrigen Strahlen hindurchgeschickt werden.The device according to the invention, on the other hand, should always be in effect and provide adequate glare protection, i.e. no handling or activity require on the part of the charioteer. This is achieved according to the invention by in front of rl: ie the front of the lamp a clear, translucent lens through which certain Rays of the light source can pass through, is set and also between the light-. - :,. source and the reflector a translucent or half-transparent Sheath is provided through which the remaining rays are sent.
Die Scheinwerfer, für :die der Erfindungsgegenstand in Anwendung kommen soll, besitzen gewöhnlich eine elelctrische Glühlampe als Lichtquelle und einen Hohlspiegel-Reflektor, der sich bis etwas über die Vorderwand der Lampe erstreckt und dort durch eine Scheibe abgeschlossen dst.The headlights for: which the subject matter of the invention is used should usually have an electric incandescent lamp as a light source and a Concave mirror reflector that extends slightly above the front wall of the lamp and closed there by a disk dst.
Einige Ausführungsbeispiele des Erfinc?ungsgegenstandes sind ,auf der Zeichnung veranschaulicht.Some embodiments of the subject matter of the invention are on illustrated in the drawing.
Abb. i zeigt einen Schnitt durch die eine Ausführungsform.Fig. I shows a section through one embodiment.
Abb.2 ist ein ähnlicher Schnitt für eine andere Ausführungsform.Fig.2 is a similar section for another embodiment.
Bei der Ausführungsform nach Abb. i ist eine elektrische Glühlampe A von geeigneter Form und Lichtstärke in dem üblichen Sockel X im Scheinwerferbefestigt. Der Scheinwerfer :besteht aus dem üblichen Halter und Reflektor XI und .aus der vorderen Scheibe X2. Nach der Erfindung endet die Glühlampe A vorn ,in einer klaren Linse B, während die Seitenwandungen C der Lampe matt oder opalartig ausgeführt sind bzw. aus einem anderen durchscheinenden oder halb-Stoff bestehen. Bei :der Ausführungsform nach Abb.2 kommt eine übliche dielte Glühlampe A zur Anwendhzag, .um die eine Hülsen D aus du@rchscheinendem oder halbdurchsichtigem Werkstoff, wie Opalglas, Mattglas o. dgl., herumgelegt ist. Die Hülse ragt etwas Über -da,s vordere Ende der Lampe hinaus. Dieses vordere Ende der Hülse D ist ;durch eine d'urchsichtige Linse B abgeschlossen.In the embodiment according to Fig. I, an electric incandescent lamp A of suitable shape and light intensity is fastened in the usual socket X in the headlamp. The headlight: consists of the usual bracket and reflector XI and the front window X2. According to the invention, the incandescent lamp A ends at the front, in a clear lens B, while the side walls C of the lamp are matt or opal-like or consist of another translucent or semi-fabric. In the case of the embodiment according to Fig. 2, a conventional incandescent lamp A is used, around which a sleeve D made of translucent or semitransparent material, such as opal glass, frosted glass or the like, is placed. The sleeve protrudes a little beyond the front end of the lamp. This front end of the sleeve D is closed by a transparent lens B.
Bei dieser Ausführungsform kann die Hülse D auch. aus klarem Material bestehen und mit einem geeigneten dürchsciieinenden oder halbdurchsichtigen. Stoff abgedeckt sein. Wenn es .gewünscht wind, kann auch in den Weg :der Lichtstrahlen, die von der Linse -herkommen, sein Schirm in Orange oder sonstiger Farbe eingebaut werden. Zweckmäßig wird man diese Farbenscheibe zwischen der Linse und der Lichtquelle anordnen.In this embodiment, the sleeve D can also. made of clear material and with a suitable translucent or semi-transparent. material be covered. If the wind is desired, it can also get in the way: the rays of light, which come from the lens, built in its shade in orange or some other color will. This color disk is expediently placed between the lens and the light source arrange.
