Description

Halter für elektrisebe,@cheinwerferlampen Es ist bereits, bekannt, mit Hilfe eines Luftstromes den Reflektor oder die Lampe einer Beleuchtungsvorrichtung zu kühlen.Holder for elektrisebe, @ headlight lamps It is already known with the help of an air stream the reflector or the lamp of a lighting device to cool.

Die vorliegende Erfindung besteht nun darin, daß der Träger der Lampenfassung einer Scheimverferlampe als Zuleitung für die Kühlluft ausgebildet ist. Vorzugsweise ist hierbei der Fassungsträger gegabelt, wobei die die Kühlluft ausblasenden Gabelzinken auf zwei gegenüberliegenden Seiten der Lampe in deren Achsenrichtung verlaufen. Die als Ausströrnöffnung ausgebildeten Endender Gabelzinken sind düsenartig gestaltet und blasen die Kühlluft in breitem Strom an dem Lampenkolben entlang. Durch die Erfindung wird also nicht nur eine gute Kühlung der Lampe selbst, sondern auch der Befestigungsteile erreicht, und vor allem wird dadurch die infolge des Gegenspiegels bewirkte Überhitzung vermieden, die vielfach ein Ausbeulen des Glaskolbens zur Folge hat. Infolge dieser Gestaltung des Halters der Lampenfassung wird fernerhin eine nur geringe Abschattung in dem vom Reflektor des. Scheinwerfers ausgehenden Strahlenbündel erreicht.The present invention now consists in that the support of the lamp socket a Scheimverfer lamp is designed as a supply line for the cooling air. Preferably the socket carrier is forked, with the fork prongs blowing out the cooling air extend on two opposite sides of the lamp in the axial direction thereof. The ends of the fork prongs designed as an outflow opening are designed like nozzles and blow the cooling air in a wide stream along the lamp envelope. Through the Invention is not only a good cooling of the lamp itself, but also the Fastening parts achieved, and above all it is the result of the counter mirror caused overheating is avoided, which often results in bulging of the glass bulb Has. As a result of this design of the holder of the lamp socket is also a only slight shadowing in the beam emanating from the reflector of the headlight achieved.

In der Zeichnung ist der Gegenstand der Erfindung in der Abb. i in Seitenansicht, in der Abb. z in Ansicht von der Refiektorseite aus und in der Abb. 3 in einem Schnitt nach der Linie A-B der Abb. i und z veranschaulicht.In the drawing, the subject of the invention is shown in Fig. I in Side view, in Fig. Z a view from the reflector side and in Fig. 3 illustrates in a section along the line A-B of Figs. I and z.

Gemäß der Zeichnung ist der gabelförmig ausgebildete Lampenträger a mit Kanälen b für die Zuleitung der Kühlluft versehen. Die Enden c der Gabelzinken, aus denen die Kühlluft austritt, sind düsenartig gestaltet.According to the drawing, the fork-shaped lamp holder a is provided with channels b for the supply of cooling air. The ends c of the fork prongs, from which the cooling air exits, are designed like nozzles.

Der Luftweg ist in den Abb. i und z durch Pfeile angedeutet. Die Zinken liegen hintereinander auf entgegengesetzten Seiten der Lampe d in Richtung der optischen Scheinwerferachse, um, wie oben erwähnt, eine möglichst geringe Abschattung zu erreichen und gleichzeitig den Raum zwischen dem Gegenspiegel f und der Lampe d zu kühlen. Der Gegenspiegel f hat bekanntlich den Zweck, Blendung infolge zu hoher Leuchtdichte des Glühfadens zu vermeiden, und wirft deshalb das von der Lampe ausgehende Strahlen, bündel auf den Reflektor e, von dem aus die Strahlen dann ausgesendet werden.The airway is indicated by arrows in Figs. I and z. The prongs lie one behind the other on opposite sides of the lamp d in the direction of the optical headlight axis in order, as mentioned above, to achieve as little shadowing as possible and at the same time to cool the space between the counter mirror f and the lamp d. The counter-mirror f has the known purpose of avoiding glare due to excessive luminance of the filament, and therefore throws the rays emanating from the lamp onto the reflector e, from which the rays are then emitted.
