Abstract
Description
Die Erfindung betrifft eine Leuchte für Fahrzeuge nach dem Oberbegriff des
Patentanspruchs 1.The invention relates to a lamp for vehicles according to the preamble of
Aus der EP 0 639 740 A1 ist eine Leuchte für Fahrzeuge bekannt, die einen lichtstreuenden Reflektor mit parallelen Vorsprüngen aufweist. Eine den Reflektor abdeckende Lichtscheibe weist innenseitig eine Reihe von parallelen Erhebungen auf, die senkrecht zu den Reflektorvorsprüngen angeordnet sind. Die Breite der sich aneinander anschließenden Erhebungen ist wesentlich größer als die Abstände benachbarter Vorsprünge des Reflektors, so daß die Leuchte von außen ein gleichmäßiges und harmonisches Erscheinungsbild liefert.From EP 0 639 740 A1, a lamp for vehicles is known that has a has light-scattering reflector with parallel projections. One the reflector covering lens has a series of parallel elevations on the inside on, which are arranged perpendicular to the reflector projections. The width of the contiguous surveys is much larger than that Distances of adjacent projections of the reflector, so that the lamp from provides a uniform and harmonious appearance on the outside.
Die DE 196 30 410 A1 bezieht sich auf Leuchten für Fahrzeuge, wobei die Form der Leuchte an die aerodynamische Form des Fahrzeugkörpers angepaßt ist. Dies bedingt jedoch in vielen Fällen eine unsymmetrische Form des Reflektors, so daß ein paraboloidförmiger Reflektor nicht verwendet werden kann. Es wird vorgeschlagen, die Reflexionsoberfläche als Reflexionsstufen vorzusehen, die zwischen benachbarten und geschlossenen Kurven von Drehparaboloiden angeordnet sind. Zur Erzeugung eines gitterförmigen Aussehens der Leuchte ist die Lichtscheibe in gitterförmige Abschnitte unterteilt, in die jeweils eine Fischaugenlinse geformt ist. Nachteilig an der bekannten Leuchte ist, daß der Reflektor eine relativ aufwendige Struktur aufweisen muß, um im Zusammenwirken mit der gitterförmigen Struktur der Lichtscheibe ein ästhetisches Aussehen zu erzeugen. DE 196 30 410 A1 relates to lights for vehicles, the shape the lamp is adapted to the aerodynamic shape of the vehicle body. In many cases, however, this requires an asymmetrical shape of the reflector, see above that a paraboloidal reflector cannot be used. It will proposed to provide the reflection surface as reflection levels that between adjacent and closed curves of paraboloids are arranged. To create a latticed appearance of the lamp the lens divided into lattice-shaped sections, each in one Fisheye lens is shaped. A disadvantage of the known lamp is that Reflector must have a relatively complex structure in order Interaction with the lattice-shaped structure of the lens is an aesthetic one To create appearance.

Vorzugsweise sind die Erhebungen (12) ebenfalls als Zylinderflächen ausgebildet. Nach einer alternativen Ausführungsform können die Erhebungen (11) des zweiten Reflektorabschnitts (8) und die Erhebungen (12) des ersten Reflektorabschnitts (7) auch im Querschnitt tropfenförmig gestaltet sein. Wichtig dabei ist, daß im Zusammenwirken mit der Formgebung der Reflektorabschnitte (7, 8) die Tropfenform so gewählt ist, daß keine Schattenbildung der von der Glühlampe (10) emittierten Lichtstrahlen an den Erhebungen erfolgt.The first reflector section (7) has parallel elevations (12), which are each extend as an arcuate cylindrical surface between the sides (5) and have such a distance from one another that the boundary lines of the Elevations (12) in the front view of the housing (1) the same distance have like the cylindrical surfaces (11) of the second reflector section (8).

Die Zylinderflächen (13) erstrecken sich im wesentlichen senkrecht zu den Zylinderflächen (11) und den Erhebungen (12) des zweiten Reflektorabschnitts bzw. des ersten Reflektorabschnitts (7). Durch Zusammenwirken der Zylinderflächen (11, 13), bzw. der Erhebungen (12) erhält die Blinkleuchte in Vorderansicht ein gitterförmiges bzw. matrixförmiges Erscheinungsbild, wobei die einzelnen Gitterelemente die gleiche quadratische Form besitzen. Alternativ können zur Bildung dieser Gitterstruktur die Zylinderflächen (11) bzw. Erhebungen (12) sich in horizontaler Richtung erstrecken, wohingegen die Zylinderflächen (13) der Lichtscheibe (2) in vertikaler Richtung verlaufen. The lens (2) has a series of parallel inward facing Elevations as cylindrical surfaces (13), the width and curvature of which correspond to the cylindrical surfaces (11) of the second reflector section (8). The Cylinder surfaces (13) extend essentially perpendicular to the Cylinder surfaces (11) and the elevations (12) of the second reflector section or the first reflector section (7). By interaction of the The flashing light in receives cylindrical surfaces (11, 13) or the elevations (12) Front view of a grid-like or matrix-like appearance, the individual grid elements have the same square shape. Alternatively the cylinder surfaces (11) or Elevations (12) extend in the horizontal direction, whereas the Cylinder surfaces (13) of the lens (2) run in the vertical direction.
Alternativ können die Zylinderflächen (11, 13) einerseits und die Erhebungen (12) andererseits eine solche unterschiedliche Breite aufweisen, daß die Leuchte in Vorderansicht ein rechteckförmiges Erscheinungsbild hat. Der Abstand der Zylinderflächen (13) zu benachbarten Zylinderflächen (13) beträgt beispielsweise 8 mm, und der Abstand der Zylinderflächen (11) zueinander beispielsweise 6 mm.Alternatively, the cylinder surfaces (11, 13) on the one hand and the elevations (12) on the other hand have such a different width that the lamp in Front view has a rectangular appearance. The distance of the Cylinder surfaces (13) to adjacent cylinder surfaces (13) is, for example 8 mm, and the distance between the cylinder surfaces (11) to each other, for example 6 mm.
Da die Zylinderflächen (11, 12, 13) zur Erzeugung der gitterförmigen Struktur unstetig zu den benachbarten Zylinderflächen (11, 12, 13) angeordnet sind, kann der Reflektor (1) eine fast beliebige Form aufweisen. Alternativ können die Zylinderflächen sich auch konkavförmig erstrecken. Der Reflektor (1) ist aus einem PC- und ABS-Kunststoffmaterial hergestellt und weist eine reflektierende Beschichtung auf. Die Lichtscheibe (2) ist aus einem transparenten PMMA-Kunststoffmaterial hergestellt.Since the cylindrical surfaces (11, 12, 13) to produce the lattice-like structure can be arranged discontinuously to the adjacent cylinder surfaces (11, 12, 13) the reflector (1) has almost any shape. Alternatively, the Cylinder surfaces also extend concavely. The reflector (1) is off made of a PC and ABS plastic material and has a reflective Coating on. The lens (2) is made of a transparent Made of PMMA plastic material.
