Description

Die Erfindung betrifft einen Reflektor für eine Leuchte, wie eine Heckleuchte, ein Scheinwerfer oder eine Innenbeleuchtung eines Kraftfahrzeuges, nach dem Oberbegriff des Anspruches 1.The invention relates to a reflector for a lamp, such as a rear lamp, a headlight or interior lighting of a motor vehicle, according to the preamble of claim 1.

Es sind Leuchten, wie beispielsweise Scheinwerfereinheiten, bekannt, bei denen in einem Leuchtengehäuse hinter einer Lichtscheibe ein Leuchtmittel angeordnet ist, dessen Licht von einem Reflektor zur Lichtscheibe reflektiert wird. Solche Leuchten benötigen einen großen Einbauraum. Außerdem lassen sich die Reflektorflächen solcher Leuchten schlecht bedampfen. Ferner kann die Lichtaustrittsfläche bei vorgegebener Bautiefe der Leuchte nicht beliebig groß ausgebildet werden, so daß in solchen Fällen mehrere Leuchtmittel erforderlich sind.Lights, such as headlight units, are known in which in a luminaire housing behind a lens a lamp is arranged, the light from a reflector for Lens is reflected. Such lights need a big one Installation space. In addition, the reflector surfaces can be such Steaming lights poorly. Furthermore, the light exit surface not designed to be of any size given the depth of the luminaire become, so that in such cases, multiple illuminants are required are.

Der Erfindung liegt die Aufgabe zugrunde, einen Reflektor dieser Art so auszubilden, daß bei geringer Bauhöhe eine größtmögliche Leuchtfläche erreicht werden kann.The invention has for its object a reflector of this type to be designed in such a way that the greatest possible with a low overall height Luminous area can be achieved.

Diese Aufgabe wird bei einem Reflektor der gattungsbildenden Art erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This task is carried out with a reflector of the generic type according to the invention with the characterizing features of the claim 1 solved.

Infolge der erfindungsgemäßen Ausbildung verläuft die Reflektorfläche in Richtung auf das Leuchtmittel ansteigend. Dadurch kann das Leuchtmittel verhältnismäßig nahe an der Reflektorfläche angeordnet sein. Das vom Leuchtmittel ausgesandte Licht fällt vollständig auf die Reflektorfläche und kann gezielt zur Lichtverteilung genutzt werden. Als Leuchtmittel wird vorzugsweise eine LED verwendet. Es reicht eine einzige LED aus, um eine große leuchtende Fläche zu erhalten. Die mit dem erfindungsgemäßen Reflektor versehene Leuchte hat nur geringe Bautiefe, da das Leuchtmittel mit nur geringem Abstand zur Reflektorfläche angeordnet werden kann.As a result of the design according to the invention, the reflector surface runs rising towards the illuminant. This can do that Illuminants arranged relatively close to the reflector surface his. The light emitted by the illuminant falls completely on the Reflector surface and can be used specifically for light distribution. An LED is preferably used as the illuminant. It is enough a single LED to get a large illuminated area. The lamp provided with the reflector according to the invention has only shallow depth because the illuminant is only a short distance from Reflector surface can be arranged.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of the invention result from the further claims, the description and the drawings.

Die Erfindung wird nachstehend anhand mehrerer in den Zeichnungen dargestellter Ausführungsbeispiele näher beschrieben. Es zeigt:

Die Fig. 1 und 6 zeigen einen Reflektor für eine Leuchte, insbesondere für Scheinwerfer von Kraftfahrzeugen. Der Reflektor weist einen' Ringkörper 5 auf, von dem in Fig. 1 nur ein Teil dargestellt ist. Das den Reflektor aufnehmende (nicht dargestellte) Gehäuse hat eine Gehäuseöffnung, die mit einer (ebenfalls nicht dargestellten) Lichtscheibe abgedeckt ist. Im Ringkörper 5 ist als Leuchtmittel eine LED 1 angeordnet, die auf einem Träger 2 über einen Haltefuß 3 befestigt ist. Die LED 1 ist mit Abstand vor einem Reflektor 4 angeordnet, der Teil des Ringkörpers 5 ist. 1 and 6 show a reflector for a lamp, in particular for headlights of motor vehicles. The reflector has a ' Ring body 5, of which only a part is shown in Fig. 1. The the reflector-receiving housing (not shown) has a Housing opening with a (also not shown) lens is covered. In the ring body 5 there is an LED as the illuminant 1 arranged, which is fastened on a support 2 via a holding foot 3 is. The LED 1 is arranged at a distance in front of a reflector 4 Is part of the ring body 5.

Der Träger 2 der LED 1 ist vorzugsweise als länglicher Steg ausgebildet (Fig. 6), der aus transparentem Kunststoff besteht und mit Leiterbahnen zur Stromzuführung versehen ist.The carrier 2 of the LED 1 is preferably designed as an elongated web (Fig. 6), which consists of transparent plastic and with conductor tracks is provided for power supply.

Der Reflektor 4 hat eine innere Reflektorfläche 6, welche die Außenseite eines Rotationskörpers 18 ist, dessen Erzeugende ein Teil einer Parabel ist, die um eine Mittellinie M rotiert wird. Der dadurch entstehende Rotationskörper 18 hat eine in der Mittellinie M liegende Spitze 8. Auf der Mittellinie M liegt auch der Brennpunkt 9 des Reflektors 4 bzw. des Rotationskörpers 18. Die Reflektorfläche 6 ist im Axialschnitt konkav gekrümmt.The reflector 4 has an inner reflector surface 6, which is the outside of a rotating body 18, the generatrix of which is part of a Is parabola that is rotated about a center line M. The resulting Rotary body 18 has a tip lying in the center line M. 8. The focal point 9 of the reflector also lies on the center line M. 4 or of the rotating body 18. The reflector surface 6 is in axial section concavely curved.

An die Reflektorfläche 6 schließt ein äußerer Reflektorteil 7 an, der über den Umfang des Reflektors 4 verläuft und sich nach außen erweitert. Der Reflektorteil 7 ist in zwei aneinander anschließende Ringteile 10, 10' unterteilt, die jeweils aus kissenförmigen Reflektorabschnitten 12 bestehen. Die in einem Ringteil 10, 10' befindlichen Reflektorabschnitte 12 sind vorteilhaft gleich groß (Fig. 6) und schließen aneinander an. Die Reflektorabschnitte 12 des Ringteiles 10 sind vorteilhaft gleich groß wie die Reflektorabschnitte 12 des Ringteiles 10'. In Draufsicht haben die Reflektorabschnitte 12 rechteckigen Umriß. In den beiden Ringteilen 10, 10' liegen die Reflektorabschnitte 12 in Höhenrichtung des Reflektors 4 hintereinander. Dadurch werden zwischen den Reflektorabschnitten Rillen 11 (Fig. 6) gebildet, die in Draufsicht auf den Reflektor 4 gerade verlaufen und sich vom Rand 16 der Reflektorfläche 6 bis zum äußeren Rand 17 des Reflektors 4 erstrecken. Der äußere Reflektor 7 überragt die Spitze des inneren Reflektorkörpers 18 und die LED 1.An outer reflector part 7 adjoins the reflector surface 6 extends over the circumference of the reflector 4 and widens outwards. The reflector part 7 is in two adjoining Ring parts 10, 10 'divided, each of pillow-shaped reflector sections 12 exist. Those located in a ring part 10, 10 ' Reflector sections 12 are advantageously the same size (Fig. 6) and connect to each other. The reflector sections 12 of the ring part 10 are advantageously the same size as the reflector sections 12 of the Ring part 10 '. In the top view, the reflector sections 12 are rectangular Outline. The reflector sections are located in the two ring parts 10, 10 ' 12 in the vertical direction of the reflector 4 one behind the other. Thereby grooves 11 are formed between the reflector sections (FIG. 6) formed, which run straight in plan view of the reflector 4 and from the edge 16 of the reflector surface 6 to the outer edge 17 of the reflector 4 extend. The outer reflector 7 projects beyond Tip of the inner reflector body 18 and the LED 1.

Der Reflektor 4 ist so ausgebildet, daß die von der LED 1 ausgesandten Strahlen 13 vollständig erfaßt und zur Lichtverteilung genutzt werden. Die von der LED 1 aus divergierend verlaufenden Lichtstrahlen 13 treffen zunächst auf die Reflektorfläche 6. Sie reflektiert die Lichtstrahlen 13 zum Reflektorteil 7, an dem sie nach außen zur (nicht dargestellten) Lichtscheibe reflektiert werden. An den kissenförmigen Reflektorabschnitten 12 werden die Lichtstrahlen 13 gestreut. Es ist auch möglich, den äußeren Reflektorteil 7 als Kegelteil auszubilden. Da keine Streuoptiken, wie die Reflektorabschnitte 12, vorgesehen sind, wird das Licht 13 in diesem Fall zu einem parallelen Lichtbündel nach außen reflektiert.The reflector 4 is designed so that the emitted by the LED 1 Beams 13 completely captured and used for light distribution become. The light rays diverging from LED 1 13 first hit the reflector surface 6. It reflects the Light rays 13 to the reflector part 7, on which they are directed outwards (Not shown) lens will be reflected. On the pillow-shaped The light beams 13 are scattered by reflector sections 12. It is also possible to use the outer reflector part 7 as a cone part train. Since no scattering optics, such as the reflector sections 12, are provided, the light 13 becomes parallel in this case Beams of light reflected outwards.

Infolge der beschriebenen Ausbildung wird erreicht, daß die Leuchte mit nur einer LED 1 eine sehr geringe Bautiefe und dabei eine große Leuchtfläche hat. Der beschriebene Reflektor 4 kann für alle Beleuchtungsarten eingesetzt werden, wie für Kraftfahrzeugheckleuchten, Kraftfahrzeugscheinwerfer, Kraftfahrzeuginnenbeleuchtungen sowie Beleuchtungseinrichtungen aller Art.As a result of the training described it is achieved that the lamp with only one LED 1, a very small installation depth and a large one Has luminous area. The reflector 4 described can be used for all types of lighting are used, such as for vehicle rear lights, Motor vehicle headlights, automotive interior lighting as well as lighting devices of all kinds.

Anstelle der kissenförmigen Reflektorabschnitte 12 können als Streuoptik auch walzenförmige Reflektorabschnitte oder beliebig anders ausgebildete Reflektionsabschnitte im äußeren Reflektorteil 7 vorgesehen sein. In diesem Fall braucht die Lichtscheibe keine Streufunktion für das Licht zu übernehmen und kann daher als einfache, kostengünstige Scheibe ausgebildet sein.Instead of the pillow-shaped reflector sections 12 can be used as a scattering optics also roller-shaped reflector sections or any other way trained reflection sections provided in the outer reflector part 7 his. In this case the lens does not need a spreading function to take over for the light and can therefore be considered simple, inexpensive Disc be formed.

Bei der Ausführungsform gemäß Fig. 2 hat der die Reflektorfläche 6a aufweisende Rotationskörper 18a eine Erzeugende, die Teil einer Ellipse ist und um die Mittellinie M rotiert wird. Der äußere Reflektorteil 7a hat eine Reflektorfläche, die auf einem Kegelmantel liegt. Er erstreckt sich vom äußeren Rand 16a der Reflektorfläche 6a des Reflektors 4a bis zum äußeren Rand 17a des Reflektorteiles 7a.
