Description

Elektrischer Fahrzeugscheinwerfer Um bei Fahrzeugscheinwerfern eine Blendung durch diffuses Licht zu vermeiden, werden sogenannte Abschirmkappen verwendet, die den vorderen Teil der Scheinwerferlampe abdecken und dafür sorgen, daß nur vom Reflektor reflektiertes Licht nach außen aus dem Scheinwerfer tritt. Bei Anwendung der Abschirmkappen wird ein gut gebündelter Lichtstrahl erzeugt, so daß eine Blendung außerhalb dieses Strahles weitestgehend unterdrückt ist.Electric vehicle headlights In order to have a To avoid glare from diffuse light, so-called shielding caps are used, which cover the front part of the headlight bulb and ensure that only from Reflector, reflected light emerges from the headlight to the outside. When applied the shielding caps a well-focused light beam is generated, so that a glare outside of this beam is largely suppressed.

Die Erfindung bezieht sich auf solche elektrische Fahrzeugscheinwerfer, die eine im Reflektor befestigte Glühlampe und eine Abschirmkappe aufweisen, wobei diese Kappe lösbar mit der Frontscheibe verbunden, ist.The invention relates to such electric vehicle headlights, which have an incandescent lamp fixed in the reflector and a shielding cap, wherein this cap is detachably connected to the windshield.

Die Abschirmkappen werden bei den bekannten Scheinwerfern entweder an der Frontscheibe oder an dem Reflektor befestigt. Gemäß der Erfindung wird nun der Vorschlag gemacht, die Abschirmkappe als Verbindungsglied zwischen Frontscheibe und, Reflektor auszubilden, um eine zusammenhängende Einheit, bestehend aus Reflektor, Lampe und Frontscheibe, zu schaffen. Diese Einheit läßt sich dann mühelos in einen Halter einsetzen oder aus diesem herausnehmen, so daß das Auswechseln beschädigter Einzelteile leicht und' ohne viel Zeitaufwand möglich. ist. Auch das Reinigen der Innenteile des Scheinwerfers wird im Hinblick auf die bekannten Scheinwerfer erheblich erleichtert, da sich die Frontscheibe auf einfache Art von der Abschirmkappe lösen läßt.The shielding caps are either with the known headlights attached to the windshield or to the reflector. According to the invention is now Made the proposal to use the shielding cap as a connecting link between the windshield and to form a reflector to form a cohesive unit consisting of a reflector, Lamp and windshield to create. This unit can then be effortlessly integrated into one Insert or remove holder from this, so that the replacement of damaged Individual parts easily and 'possible without spending a lot of time. is. Also cleaning the Internal parts of the headlight becomes significant in view of the known headlights facilitated because the front screen can be easily detached from the shielding cap leaves.

Weiterhin wird das Einlegen des Dichtungsringes zwischen Reflektor und Frontscheibe vereinfacht, weil der Ring bereits vor dem Einsetzen der Einheit in das eigentliche Scheinwerfergehäuse durch Befestigen bzw. Anschrauben der Frontscheibe an die Abschirmkappe festgeklemmt werden kann.Furthermore, the insertion of the sealing ring between the reflector and front screen simplified because the ring is already inserted before the unit is inserted into the actual headlight housing by fastening or screwing on the windshield can be clamped to the shielding cap.

Die Zeichnung zeigt als Ausführungsbeispiel der Erfindung einen Scheinwerfer im Längsschnitt.The drawing shows a headlight as an embodiment of the invention in longitudinal section.

Der Reflektor a, der von parabolischer oder anderer Gestalt sein kann, weist an seinem Rande einen Kragen auf, in den ein Dichtungsring b aus Gummi oder gummiartigem Werkstoff eingelegt ist. Die Lampenfassung c ist an der Rückseite des Reflektors befestigt und so geformt, daß sie von rückwärts eingesetzt werden kann. Als Lampe d wird vorzugsweise eine Bauart mit Vorfokussieru.ng verwendet. Am Reflektor ist weiter koaxial mit der Fassung eine undurchsichtige Kappe e befestigt, die im wesentlichen zylindrische Gestalt hat mit Öffnungen wie f, g, durch die das Licht von der Lampe. auf den Reflektor fallen kann. Die axiale Länge der Kappe ist so gewählt, daß ihre verschlossene Stirnseite dicht hinter der Frontscheibe h liegt. Diese Frontscheibe kann aus Glas bestehen, vorteilhafter aber aus einem lichtdurchlässigen Kunstharz gegossen sein. An ihrem Rande ist ein kurzer zylindrischer Ring i angeformt, der gegen den Dichtungsring b am Reflektor drückt.The reflector a, which can be parabolic or other shape, has at its edge on a collar in which a sealing ring b made of rubber or rubber-like material is inserted. The lamp holder c is on the back of the Reflector attached and shaped so that it can be inserted from the rear. A type with prefocusing is preferably used as lamp d. At the reflector an opaque cap e is also attached coaxially with the socket, which is in the essentially cylindrical in shape with openings like f, g through which the light from the lamp. fall on the reflector. The axial length of the cap is like this chosen that its closed end face is close behind the front pane h. This front pane can consist of glass, but more advantageously of a translucent one Cast resin. A short cylindrical ring i is formed on its edge, which presses against the sealing ring b on the reflector.

Um die Frontscheibe lösbar am Reflektor a befestigen zu können, sitzt in der Stirnfläche der Kappe eine Schraube j, die durch ein Mittelloch in der Frontscheibe hindurchtritt und in die Kappenmutter k eingeschraubt wird. Umgekehrt kann die Schraube auch durch ein Loch in der Frontscheibe eingeführt und in ein Gewindeloch in der Kappe eingeschraubt werden.In order to be able to releasably attach the front screen to the reflector a, sits A screw j in the end face of the cap, which goes through a central hole in the windshield passes through and is screwed into the cap nut k. Conversely, the screw can also inserted through a hole in the faceplate and into a threaded hole in the Cap to be screwed in.

Die Scheinwerfereinheit aus Reflektor und Frontscheibe kann in einen Halber m von geeigneter Formgebung und Ausführung eingesetzt werden und wird von einer Krallen gehalten, die mittels der Schraube o am Halter befestigt ist.The headlight unit consisting of reflector and windshield can be integrated into one Half m of suitable shape and design are used and is used by held by a claw which is fastened to the holder by means of the screw o.
