ScheinwerferHeadlights

Die Erfindung betrifft einen Scheinwerfer, bestehend aus einem zylindrischen Körper, welcher an einem seiner Enden durch eine Glasscheibe verschlossen ist, und in dem eine Lampe und ein Spiegel untergebracht sind, deren Achsen mit der des Körpers zusammenfallen. The invention relates to a headlamp consisting of a cylindrical body which is closed at one of its ends by a pane of glass and in which a lamp and a mirror are housed, the axes of which coincide with that of the body.

Aufgabe der Erfindung ist die Schaffung eines luftdichten und belüfteten Scheinwerfers. The object of the invention is to create an airtight and ventilated headlight.

809616/0910809616/0910

Gemäß der Erfindung sind der Spiegel und die Lampe im Inneren einer zylindrischen Büchse eingebaut, die im Körper koaxial zu diesem angeordnet ist, dergestalt, daß ein Durchlaß mit ringförmigem Querschnitt zwischen dem Körper und der Büchse ausgebildet ist, daß das vordere Ende der Büchse mit einem Zwischenraum zur Ciasscheibe angeordnet ist, so daß der Durchlaß mit dem Inneren der Büchse über diesen Zwischenraum in Verbindung steht und das hintere Ende der Büchse sich an den Außenrand eines ringförmigen Teiles anschließt, dessen Achse mit derjenigen des Körpers des Scheinwerfers zusammenfällt, welches vom Boden des Körpers einen Abstand aufweist und einen Lüfter trägt, wobei Durchlässe im Spiegel und im Träger der Lampe ausgebildet sind, so daß eine Zirkulation der Luft in geschlossenem Kreislauf ermöglicht ist, welche durch den Lüfter in Bewegung gebracht ist, in den Raum zwischen dem ringförmigen Teil und den Boden des Scheinwerfers gedrückt wird, dann in den ringförmigen Durchlaß und wieder zum Lüfter zurückkehrt, wobei sie in der Achse des Scheinwerfers um die Lampe herum zirkuliert. Die sich beim Strömen um die Lampe erwärmende Luft wird auf ihrem Wege durch den ringförmigen Durchlaß durch Wärmeaustausch mit der Umgebungsluft durch den Körper des Scheinwerfers hindurch gekühlt; der Körper ist vorteilhaft mit Rippen versehen, um diesen Wärmeaustausch zu intensivieren. Die Büchse kann aus zwei, mit den Enden aneinanderstoßenden Teilen ausgeführt sein, wobei der Rand des Spiegels zwischen den beiden Teilen der Büchse festgehalten wird.According to the invention, the mirror and the lamp are installed inside a cylindrical sleeve which is coaxial in the body is arranged to this, such that a passage with an annular cross-section between the body and the sleeve is designed that the front end of the sleeve is arranged with a gap to the Ciasscheibe, so that the passage communicates with the interior of the sleeve via this space in communication and the rear end of the Bushing adjoins the outer edge of an annular part, the axis of which with that of the body of the headlamp coincides, which has a distance from the bottom of the body and carries a fan, with passages are formed in the mirror and in the support of the lamp, so that a circulation of the air in a closed circuit is possible which is set in motion by the fan, into the space between the annular part and the floor of the headlamp, then into the annular passage and returns to the fan, circulating around the lamp in the axis of the headlamp. Which Air heating as it flows around the lamp is on its way through the annular passage by heat exchange cooled with the ambient air through the body of the headlamp; the body is advantageously provided with ribs, to intensify this heat exchange. The bushing can consist of two parts that are butted together at the ends with the edge of the mirror held between the two parts of the sleeve.

Ein nicht beschränkendes Ausführungsbeispiel der Erfindung ist in der einzigen Figur der Zeichnung dargestellt und wird im folgenden näher beschrieben·A non-limiting embodiment of the invention is shown in the single figure of the drawing and is described in more detail below

Der Scheinwerfer weist einen zylindrischen, mit Rippen 12 versehenen Körper 10 auf, welche die Kühlung des Scheinwerfers verbessern. An einem seiner Enden ist er durch einen Boden 14, der durch Schrauben unter Zwischenlegen einer Dichtung 16 befestigt ist, und an seinem anderen Ende durch eine Glasscheibe 18 verschlossen, die in eine durch Schrauben unter Zwischenlegen einer Dichtung 21 befestigten Einfassung 20 eingesetzt ist.The headlight has a cylindrical, ribbed 12 provided body 10, which improve the cooling of the headlight. At one of its ends it is through a floor 14, which is fastened by screws with the interposition of a gasket 16, and at its other end by a pane of glass 18 closed, which is fastened in an enclosure 20 is used.

Im Inneren des Körpers 10 und koaxial zu diesem ist eine Büchse 22 eingesetzt, deren Durchmesser etwas kleiner als der Innendurchmesser des Körpers ist, so daß zwischen ihnen ein Durchlaß 24 mit Ringquerschnitt ausgebildet ist· Die Büchse 1st im Körper 10 durch Stopfen 26 und Blattfedern zentriert.Inside the body 10 and coaxial to this a sleeve 22 is used, the diameter of which is slightly smaller than is the inner diameter of the body so that a passage 24 with an annular cross-section is formed between them Bushing is centered in body 10 by plugs 26 and leaf springs.

Das vordere Ende der Büchse 22 ist mit einem gewissen Abstand von der Scheibe 18 angeordnet, dergestalt, daß der Durchlaß 24 mit dem Inneren der Büchse an diesem Ende in Verbindung steht.The front end of the sleeve 22 is arranged at a certain distance from the disc 18, such that the Passage 24 communicates with the interior of the sleeve at that end.

Das hintere Ende der Büchse stützt sich am Außenrand eines ringförmigen Teiles 30 ab, das mit Bolzen 31 am Boden 14The rear end of the bushing is supported on the outer edge of an annular part 30, which is fastened to the bottom 14 with bolts 31

Dieses Teil weist in seiner Mitte einen Kragen auf, an dem ein Lüfter 32 befestigt ist; dieser läßt die Luft im Durchlai3 24 und im Inneren der Büchse 22 in geschlossenem Kreislauf zirkulieren.is attached. This part has in its center a collar to which a fan 32 is attached; this leaves the air in the passage 24 and inside the sleeve 22 in closed Circulate circulation.

Die Büchse 22 besteht aus zwei Teilen, die durch einen Ring 34 verbunden sind; an diesem sind außerdem der Rand eines Spiegels 36 und Laschen 38 befestigt, die einen Rückstrahlspiegel 40 tragen«, Um den Ring 34 herum ist im Körper 10 eine Ringnut eingearbeitet, um einen annähernd konstanten Querschnitt für den Durchlaß 24 zu schaffen.The sleeve 22 consists of two parts which are connected by a ring 34; at this one is also the edge of one Mirror 36 and tabs 38 attached to a rearview mirror 40 ', around the ring 34 an annular groove is worked into the body 10, around an approximately constant one To create cross-section for the passage 24.

Der Scheinwerfer ist mit einer Lampe Ί2 mit langgestreckter Form ausgerüstet, die koaxial zum Körper 10 angeordnet und an ihren beiden Enden gelagert und mit Strom versorgt ist. Das hintere Auflager 48 der Lampe ist mit breiten Öffnungen versehen, die ihre Belüftung ermöglichen. Das vordere Ende der Lampe ist durch Laschen 38 abgestützt«The headlight comes with a lamp Ί2 with elongated Equipped form, which is arranged coaxially to the body 10 and mounted at both ends and supplied with power. The rear seat 48 of the lamp is provided with wide openings to allow its ventilation. The front end the lamp is supported by brackets 38 "

Außerdem weist der Scheinwerfer eine Abdeckhülse 60 auf, die vor einer zentralen Öffnung des Spiegels 36 und koaxial zu diesem angeordnet ist und die Lampe umgibt, sobald die Stromversorgung unterbrochen wird, um die von den noch glühenden Elektroden ausgesandte Strahlung abzuschirmen,,In addition, the headlight has a cover sleeve 60 which is arranged in front of a central opening of the mirror 36 and coaxially to this and surrounds the lamp as soon as the power supply is applied interrupted in order to shield the radiation emitted by the electrodes that are still glowing,
