Description

Signalleuchte für Fahrzeuge Die Erfindung bezieht sich auf eine Signalleuchte für Fahrzeuge mit zwei Glühlampen, die in einem im wesentlichen durch einen Hohlspiegel und ein Lichtfenster umgrenzten Raum untergebracht sind. Bei den bekannten Leuchten dieser Art wurde nicht die gesamte für den Lichtaustritt verfügbare Oberfläche des Lichtfensters gleichmäßig ausgeleuchtet. Die dabei entstehende ungleichmäßige Lichtverteilung wirkt sich besonders ungünstig aus, wenn die beiden Lampen eine stark unterschiedliche Lichtstärke haben und die wesentlich schwächere Lampe zur Erzielung einer von der Farbe des Lichtfensters abweichenden Lichtfärbung durch ein lichtdurchlässiges Farbfilter abgeschirmt ist. In diesem Fall ergibt die ungleichmäßige Lichtverteilung unterschiedliche Farbtönungen auf dem Lichtfenster, die zu Fehldeutungen Anlaß geben können.Signal lamp for vehicles The invention relates to a signal lamp for vehicles with two incandescent lamps, one of which is essentially through a concave mirror and a light window enclosed space are housed. With the well-known lights not the entire surface of the Light window evenly illuminated. The resulting uneven light distribution has a particularly unfavorable effect if the two lamps are very different Have luminous intensity and the much weaker lamp to achieve one of the Color of the light window deviating light color through a translucent color filter is shielded. In this case, the uneven light distribution results in different ones Shades of color on the light window that can give rise to misinterpretations.

Diese Mängel werden dadurch behoben, daß sich gemäß der Erfindung die Glühfäden der beiden Lampen mindestens annähernd senkrecht zur optischen Achse des Spiegels erstrecken, wobei der Glühfaden der einen Lampe zwischen dem Hohlspiegelbrennpunkt und dem Lichtfenster innerhalb eines rohrförmigen farbigen Lichtfilters angeordnet ist.These shortcomings are remedied in that, according to the invention the filaments of the two lamps at least approximately perpendicular to the optical axis of the mirror, with the filament of one lamp between the concave mirror focal point and the light window disposed within a tubular colored light filter is.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im senkrechten Mittelschnitt dargestellt.The drawing shows an exemplary embodiment of the subject matter of the invention shown in the vertical center section.

In einem topfförmigen Gehäuse 5 befindet sich ein Hohlspiegel 6, der zusammen mit einem Deckelring 7 und einem darin eingesetzten Lichtfenster 8 einen Raum 9 abgrenzt. Die durch den Hohlspiegelbrennpunkt F gehende optische Achse durchdringt das Lichtfenster 8 im Punkt L und den Hohlspiegelscheitel im Punkt S. In dem Raum 9 befinden sich zwei Soffittenlampen 10 und 11, die eine unterschiedliche Lichtstärke haben und deren in ihrer Mittelachse sich erstreckende Glühfäden senkrecht zur optischen Achse verlaufen.In a cup-shaped housing 5 there is a concave mirror 6, the together with a cover ring 7 and a light window 8 inserted therein Space 9 delimits. The optical axis passing through the concave mirror focal point F penetrates it the light window 8 at point L and the concave mirror vertex at point S. In the room 9 there are two festoon lamps 10 and 11, which have a different light intensity and their filaments extending in their central axis perpendicular to the optical Axis run.

Die Mittelachse der stärkeren Lampe 10 schneidet den Abschnitt FS der optischen Achse in der Nähe des Brennpunktes F, während die Achse der schwächeren Lampe 11 den Abschnitt FL dieser Achse schneidet. Die Lampe 11 ist durch ein rohrförmiges farbiges Lichtfilter 12 ummantelt. Das eine Ende dieses Filters sitzt in dem kragenförmigen Rand 13 eines Tellers 15, der einen um das andere Ende des Filters herumgebogenen Haltelappen 14 hat. Der Teller ist an einer gleichzeitig auch zur Stromzuführung der Lampen 10 und 11 dienenden und am Hohlspiegel 6 befestigten Traglasche 16 angebracht. Die zwei anderen Stromzuführungsglieder dieser Lampen sind Blattfedern 17 und 18. Die Blattfeder 18 ist mittels eines Bolzens 19 an einer Lasche 20 quer zur Mittelachse der Lampe 11 schwenkbar angelenkt, damit die Lampe leicht eingesetzt und im Bedarfsfall ausgewechselt werden kann. Das an der Lasche 20 anliegende Ende der Blattfeder hat eine flache Erhebung 21, die in eine zur Versteifung dienende Längssicke 22 der Lasche einrastet. Die Blattfeder 17 und die Lasche 20 sind isoliert am Hohlspiegel 16 befestigt und mit Anschlußklemmen üblicher Art verbunden.The central axis of the stronger lamp 10 intersects the section FS of the optical axis in the vicinity of the focal point F, while the axis of the weaker lamp 11 intersects the section FL of this axis. The lamp 11 is encased by a tubular colored light filter 12. One end of this filter sits in the collar-shaped edge 13 of a plate 15 which has a holding tab 14 bent around the other end of the filter. The plate is attached to a support bracket 16 which is also used to supply power to the lamps 10 and 11 and is fastened to the concave mirror 6. The two other power supply members of these lamps are leaf springs 17 and 18. The leaf spring 18 is pivotably articulated by means of a bolt 19 on a bracket 20 transversely to the central axis of the lamp 11 so that the lamp can be easily inserted and replaced if necessary. The end of the leaf spring resting on the tab 20 has a flat elevation 21 which engages in a longitudinal bead 22 of the tab which is used for reinforcement. The leaf spring 17 and the tab 20 are insulated and attached to the concave mirror 16 and connected to terminals of the usual type.

Die Lampe 11 liefert in Verbindung mit dem vorzugsweise signalrot gefärbten lichtdurchlässigen Filter 12 ein Licht, welches sehr gleichmäßig über das Lichtfenster 8 verteilt und daher auf große Entfernung sowie infolge der Anordnung gemäß der Erfindung über einen genügend weiten Winkelbereich sichtbar ist. Das von der Lichtquelle 10 ausgesandte starke Lichtbündel durchdringt im wesentlichen nur das Lichtfenster 8, das entweder glasklar oder hellgelb gefärbt ist. Dieses Licht ist zur Beleuchtung der rückwärtigen Fahrbahn bzw. zur Anzeige von Bremsvorgängen und/oder als Blinklicht zur Fahrtrichtungsanzeige geeignet.The lamp 11 supplies in connection with the preferably signal red colored translucent filter 12 a light which is very evenly over the light window 8 distributed and therefore at a great distance and as a result of the arrangement according to the invention is visible over a sufficiently wide angular range. That from the light source 10 emitted strong light bundle essentially only penetrates the light window 8, which is either clear or light yellow in color. This light is used to illuminate the rear lane or to display braking processes and / or suitable as a flashing light to indicate the direction of travel.
