Description

Die Erfindung betrifft Beleuchtungseinrichtung für Fahrzeuge mit einem Gehäuse, mit einem ortsfesten Reflektor, der von vorne in das Gehäuse eingesetzt ist und an einem nach vorne weisenden Anschlag des Gehäuses anliegt, mit einer den Reflektor am Anschlag des Gehäuse halternden Halteeinrichtung, mit einer Lampe, die von der Rückseite des Gehäuses her in eine von Gehäuse und Reflektor gebildete Aufnahmeöffnung eingesetzt ist und den Reflektor an dem Gehäuse befestigt, und mit einer Abschlussscheibe, die mit einem in Einsetzrichtung des Reflektors weisenden Randbereich auf einen vorderen Befestigungsrand des Gehäuses aufgesetzt und an diesem befestigt ist.The invention relates to lighting device for vehicles with a housing, with a stationary reflector, which is inserted from the front into the housing and bears against a stop facing the front of the housing, with a reflector supporting the stop of the housing holding device, with a lamp, the is inserted from the rear side of the housing into a receiving opening formed by housing and reflector and the reflector attached to the housing, and with a cover plate which is placed with a pointing in the direction of insertion of the reflector edge region on a front mounting edge of the housing and secured thereto ,

Eine solche Beleuchtungseinrichtung für Fahrzeuge ist aus der DE - U - 297 24 219 bekannt. Die Beleuchtungseinrichtung weist ein aus Kunststoff bestehendes topfförmiges Gehäuse auf, dessen vordere Öffnung durch eine lichtdurchlässige Abschlussscheibe abgeschlossen ist. In dem Gehäuse sind ein Reflektor eines Scheinwerfers und seitlich neben dem Scheinwerfer ein Reflektor einer ortsfestenLeuchte angeordnet. Eine Lampe, welche eine Glühlampe ist, ist in eine von der Außenseite des Gehäuses her in eine Aufnahmeöffnung mittels eines Drehverschlusses eingesetzt. Die Aufnahmeöffnung ist von dem Gehäuse und dem Reflektor gebildet. Beim Zusammenbau der Beleuchtungseinrichtung wird zuerst der Reflektor durch eine vordere Öffnung des Gehäuses in eine Steckaufnahme des Gehäuses eingeführt. Durch die Steckverbindung ist der Reflektor solange gehalten, bis die Lampe montiert ist und den Reflektor sicher haltert. Somit bilden die Aufnahmeöffnung von Gehäuse und Reflektor, die Steckverbindung und die Lampe eine Befestigungseinrichtung für den Reflektor. An dem vorderen Rand des Reflektors ist eine Lichtscheibe befestigt, an deren Vorderseite wie in Fig. 1 gezeigt ein Abdeckrahmen angrenzt. Die Ausführung entspricht dem Scheinwerfer für den Opel Astra II mit der Hella Bestellnummer 1 EG 007 640-311. Dadurch ist auch bei einem Wechsel der Lampe der Reflektor ortsfest gehalten. Hierbei dient der Abdeckrahmen als Halteeinrichtung. Wegen dem an die Lichtscheibe angrenzenden Abdeckrahmen kann bei einem unsachgemäßen Einsetzen des Abdeckrahmens oder bei einem vibrierenden Abdeckrahmen die Lichtscheibe der Leuchte beschädigt werden. Weiterhin verkleinert sich wegen dem Abdeckrahmen die Lichtaustrittsfläche der Leuchte.Such a lighting device for vehicles is from the DE - U - 297 24 219 known. The lighting device has an existing plastic cup-shaped housing, the front opening is closed by a translucent lens. In the housing, a reflector of a headlamp and the side of the headlamp, a reflector of a stationary light are arranged. A lamp, which is an incandescent lamp, is inserted into one from the outside of the housing into a receiving opening by means of a rotary shutter. The receiving opening is formed by the housing and the reflector. When assembling the lighting device, the reflector is first inserted through a front opening of the housing in a plug-in receptacle of the housing. Through the connector, the reflector is held until the lamp is mounted and securely holds the reflector. Thus, the receiving opening of the housing and reflector, the plug connection and the lamp form a fastening device for the reflector. At the front edge of the reflector, a lens is attached, at the front as in Fig. 1 shown a cover frame adjacent. The version corresponds to the headlight for the Opel Astra II with the Hella order number 1 EG 007 640-311. This is also the case of a change of the lamp Reflector held stationary. Here, the cover serves as a holding device. Because of the adjacent to the lens cover frame can be damaged in improper insertion of the cover or a vibrating cover the lens of the lamp. Furthermore, because of the cover frame, the light exit surface of the luminaire decreases.

Aufgabe der Erfindung ist es, den im Obergriff des Anspruchs 1 beschriebenen Scheinwerfer für Fahrzeuge derart zu gestalten, dass der Reflektor bei einem Wechsel der Lampe auch dann ortsfest gehalten ist, wenn die Lichtaustrittfläche des ortsfesten Reflektors möglichst groß gestaltet ist und keine lichttechnischen Flächen des Reflektors zur Halteeinrichtung des Reflektors gehören. Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass die Halteeinrichtung mit mindestens einer Anlagefläche der Abschlussscheibe den Reflektor zwischen ihr und dem Anschlag des Gehäuses haltert, wobei die Anlagefläche dem Befestigungsrand des Gehäuses zugewandt ist.The object of the invention is to make the described in the preamble of claim 1 headlights for vehicles such that the reflector is also held stationary when changing the lamp when the light exit surface of the fixed reflector is designed to be as large as possible and no lighting surfaces of the reflector belong to the holding device of the reflector. To achieve this object, the invention in conjunction with the preamble of claim 1, characterized in that the holding device with at least one contact surface of the cover plate holds the reflector between it and the stop of the housing, wherein the contact surface faces the attachment edge of the housing.

Der besondere Vorteil der Erfindung besteht darin, dass die Anlagefläche der Abschlussscheibe eine Seite eines Raums begrenzt, der von dem äußeren Randbereich der Abschlussscheibe und dem Befestigungsrand des Gehäuses gebildet ist und die Anlagefläche der Abschlussscheibe mindestens an einem nach außen ragenden und in den Raum hineinragenden Ansatz des Reflektors anliegt. Dadurch kann die optisch wirksame Reflexionsfläche des Reflektors bis sehr nahe an die innere Seite des in Einsetzrichtung des Reflektors weisenden Randbereichs der Abschlussscheibe heranreichen. Weiterhin ist bei einer optikfreien Abschlussscheibe die Halteeinrichtung des Reflektors nicht störend zu sehen und die Abschlussscheibe muss keine nach innen vorspringende Halteansätze aufweisen.The particular advantage of the invention is that the contact surface of the cover plate delimits one side of a space which is formed by the outer edge region of the lens and the attachment edge of the housing and the contact surface of the cover plate at least on an outwardly projecting and projecting into the space approach of the reflector is applied. As a result, the optically effective reflection surface of the reflector can reach very close to the inner side of the edge region of the lens in the insertion direction of the reflector. Furthermore, the holding device of the reflector is not disturbing to see in an optic-free lens and the lens must have no inwardly projecting retaining lugs.

Auch bei groben Toleranzen des Reflektors und des Gehäuses ist ein klapperfreies Halten des Reflektors durch die Halteeinrichtung gegeben, wenn ein erster Ansatz der Halteeinrichtung starr und mindestens ein zweiter Ansatz federnd ausgeführt ist, wobei zumindest der federnde zweite Ansatz an der Abschussscheibe anliegt. Durch die federnden Ansätze ist immer eine spielfreie Halterung zwischen den Anlageflächen des Reflektors und der Abschlussscheibe sicher.Even with coarse tolerances of the reflector and the housing a rattle-free holding of the reflector is given by the holding device when a first approach of the holding device is rigid and at least a second approach is resilient, at least the resilient second approach is applied to the firing disk. Due to the resilient lugs always a play-free mounting between the contact surfaces of the reflector and the lens is safe.

Der Reflektor ist auch bei größeren Abmessungen vibrationsfrei an seinem äußeren Rand gehalten, wenn die Halteeinrichtung mindestens einen in Einsetzrichtung des Reflektors weisenden Vorsprung aufweist, der mit seinem freien Endabschnitt an einer Fläche des Anschlag des Gehäuse anliegt, wobei der Vorsprung in eine Steckaufnahme des Gehäuses eingeschoben ist und der Grund der Aufnahmeöffnung der Anschlag des Gehäuses ist. In diesem Zusammenhang ist es weiterhin vorteilhaft, wenn der starre und federnde Ansatz der Halteeinrichtung an dem Vorsprung angeformt sind.The reflector is held vibration-free at its outer edge even with larger dimensions, when the holding device has at least one pointing in the insertion direction of the reflector projection which abuts with its free end portion on a surface of the stop of the housing, wherein the projection inserted into a plug receptacle of the housing is and the reason of the receiving opening is the stop of the housing. In this context, it is also advantageous if the rigid and resilient approach of the holding device are integrally formed on the projection.

In den beiden Figuren ist ein Teil einer Beleuchtungseinrichtung für Fahrzeuge dargestellt. Die Beleuchtungseinrichtung weist ein aus Kunststoff bestehendes topfförmiges Gehäuse 1 auf, in das in Einsetzrichtung 8 ein Scheinwerfer (nicht dargestellt) und eine Leuchte 17 eingesetzt ist. Die Leuchte 17 ist eine Blinkleuchte und weist einen schalenförmigen Reflektor 2 auf, der zusammen mit dem Gehäuse 1 eine Aufnahmeöffnung 6 für eine Lampe 5 bildet. Die Lampe 5, deren Längsachse parallel zur Einsetzrichtung 8 verläuft, ist von der äußeren Rückseite des Gehäuses 1 mittels eines Drehverschlusses 19 eingesetzt. Dabei drückt die Lampe 5 den Reflektor 2 mit einem seine Aufnahmeöffnung 6 umgebenden Hals 18 gegen eine als Anschlag 3 dienende ringförmige Fläche des Gehäuses 1 und richtet den Reflektor 2 genau zu einem Glühfaden der Lampe 5 aus.In the two figures, a part of a lighting device for vehicles is shown. The lighting device has a pot-shaped housing 1 made of plastic, in which in the insertion direction 8, a headlight (not shown) and a lamp 17 is used. The lamp 17 is a flashing light and has a cup-shaped reflector 2, which forms a receiving opening 6 for a lamp 5 together with the housing 1. The lamp 5, whose longitudinal axis is parallel to the insertion direction 8, is inserted from the outer rear side of the housing 1 by means of a rotary closure 19. The lamp 5 pushes the reflector 2 with a his Receiving opening 6 surrounding neck 18 against serving as a stop 3 annular surface of the housing 1 and aligns the reflector 2 exactly to a filament of the lamp 5.

Eine Halteeinrichtung (4) des Reflektors 2 weist an sich gegenüberliegen Seitenrändern des Reflektors 2 angeformte zungenartige Vorsprünge 15 auf, die in Einsetzrichtung 8 weisen und jeweils in eine Steckaufnahme 16 des Gehäuses 1 eingreifen. Die beiden zungenartigen Vorsprünge 15 liegen mit ihren Stirnflächen an Flächen des Anschlags 3 des Gehäuse 1 an, die von dem Grund der Steckaufnahmen 16 gebildet sind. An die breiten Seitenflächen der zungenartigen Vorsprünge 15 sind nach außen abstehende Ansätze 13 und 14 angeformt. An jedem zungenartigen Vorsprung 15 ist ein starrer Ansatz 13 und zwei federnde Ansätze 14 angebracht. Zwischen den beiden federnden Ansätzen 14 ist der starre Ansatz 13 angeordnet.A holding device (4) of the reflector 2 has tongue-like projections 15, which are formed on opposite side edges of the reflector 2, which point in the insertion direction 8 and in each case engage in a plug-in receptacle 16 of the housing 1. The two tongue-like projections 15 rest with their end faces on surfaces of the stopper 3 of the housing 1, which are formed by the bottom of the plug-in receptacles 16. To the broad side surfaces of the tongue-like projections 15 outwardly projecting lugs 13 and 14 are formed. At each tongue-like projection 15, a rigid projection 13 and two resilient lugs 14 is attached. Between the two resilient lugs 14 of the rigid projection 13 is arranged.

Die Vorderseite des Gehäuses 1 ist durch eine schalenförmige Abschlussscheibe 7 abgedeckt, die mit ihrem umlaufenden Randbereich 9, der in Einsetzrichtung 8 weist, an dem vorderen Befestigungsrand 10 des Gehäuses 1 befestigt ist. Der Randbereich 9 der Abschlussscheibe 7 taucht mit einem freien Randabschnitt 20 in ein in ein Bett des Befestigungsrandes eingebrachtes Dichtungsmittel 21 ein. Das Dichtungsmittel 21 kann ein Klebstoff sein. Die Abschlussscheibe 7 ist durch eine c-förmige Feder, die den Randbereich 9 der Abschlussscheibe 7 und den Befestigungsrand 10 des Gehäuses 1 umgreift, an dem Gehäuse 1 sicher gehalten bis der Klebstoff ausgehärtet ist. Zumindest im Bereich der Halteinrichtungen 4 verspringt der Randabschnitt 20 der Abschussscheibe 7 nach außen und bildet an der Innenseite der Abschlussscheibe eine Stufe. Die Stufe bildet zusammen mit dem vorderen Befestigungsrand 10 des Gehäuses 1 einen Raum 12 in den die Ansätze 13 und 14 sich hinein erstrecken. Der Raum 12 kann von einer umlaufenden Nut gebildet sein. Zumindest die federnden Ansätze 14 liegen an einer Anlagefläche 11 der Abschlussscheibe 7 an. Die Anlagefläche 11 begrenzt den Raum 12 entgegen der Einsetzrichtung 8 gesehen.The front of the housing 1 is covered by a cup-shaped cover plate 7, which is fixed with its peripheral edge region 9, which faces in the direction of insertion 8, on the front fastening edge 10 of the housing 1. The edge region 9 of the lens 7 dives with a free edge portion 20 in a introduced into a bed of the fastening edge sealant 21 a. The sealant 21 may be an adhesive. The cover plate 7 is held securely by a c-shaped spring, which surrounds the edge region 9 of the cover plate 7 and the attachment edge 10 of the housing 1 to the housing 1 until the adhesive has cured. At least in the region of the holding devices 4, the edge portion 20 of the firing disk 7 swings outwards and forms a step on the inside of the cover disk. The step, together with the front attachment edge 10 of the housing 1, forms a space 12 into which the lugs 13 and 14 extend. The space 12 may be formed by a circumferential groove. At least the resilient lugs 14 are present a contact surface 11 of the lens 7 at. The contact surface 11 defines the space 12 opposite to the insertion direction 8 seen.

Bei einem Zusammenbau des Scheinwerfers wird zuerst der Reflektor 2 in das Gehäuse 1 eingesetzt bis dieser an den Anschlägen 3 des Gehäuses 1 anliegt. Danach wird die Lampe 5 von der Rückseite des Gehäuses 1 her in die von Gehäuse 1 und Reflektor gebildete Aufnahmeöffnung 6 mittels eines Drehverschlusses 19 eingesetzt und haltert den Reflektors 2 am Gehäuse 1. Dabei ist sichergestellt, dass sich beim Eindrehen der Lampe 5 in die Aufnahmeöffnung 6 der Reflektor 2 sich genau zur Lampe 5 ausrichtet. Anschließend wird die Abschlussscheibe 7 auf das Gehäuse 1 aufgesetzt und an diesem befestigt. Danach drückt die Abschlussscheibe 7 mit ihren beiden Anlageflächen 11 die Vorsprünge 15 des Reflektors 2 gegen Flächen des Anschlags 3 des Gehäuses 1. Dadurch ist der Reflektor 2 auch bei einem Wechsel der Lampe 5 weitestgehend spielfrei und im Fahrbetrieb vibrationsfrei gehalten. Nach einem Einsetzen einer neuen Lampe 5 zentriert sich der Reflektor 2 selbsttätig zur Lampe 5.In an assembly of the headlamp, the reflector 2 is first inserted into the housing 1 until it rests against the stops 3 of the housing 1. Thereafter, the lamp 5 is inserted from the back of the housing 1 forth in the receptacle formed by housing 1 and reflector 6 by means of a rotary closure 19 and supports the reflector 2 on the housing 1. It is ensured that when screwing the lamp 5 into the receiving opening 6, the reflector 2 aligns exactly to the lamp 5. Subsequently, the cover plate 7 is placed on the housing 1 and secured thereto. Thereafter, the cover plate 7 presses with its two contact surfaces 11, the projections 15 of the reflector 2 against surfaces of the stopper 3 of the housing 1. As a result, the reflector 2 is largely free of play even with a change of the lamp 5 and kept vibration-free while driving. After inserting a new lamp 5, the reflector 2 is centered automatically to the lamp fifth

Der zwischen dem Reflektor 2 und dem Befestigungsrand 10 bestehende Spalt kann durch ein Abdeckelement abgedeckt sein.The existing between the reflector 2 and the mounting edge 10 gap may be covered by a cover.
