Abstract

The signal light has an incandescent lamp (8) behind a coloured transparent filter (6). A Fresnel lens (7) is located on the outside of the filter and behind the transparent colourless cover (10) closing the light's casing. The Fresnel lens prevents incident sunlight making the light appear alight when it is not. Incident sunlight does not pass through the filter to re-emerge from the light as coloured. The advantage lies in the simplicity of the design. No reflector is needed: only a filter and a Fresnel lens. No, problems with thermal expansion are experienced. The casing (4) of the light is made of dark opaque material.

Description

Farbig strahlende Signalleuchte für ein Fahrzeug Brightly colored signal light for a vehicle

Die Erfindung betrifft eine farbig strahlende Signalleuchte gemäß dem Oberbegriff des Patentanspruchs. Derartige Signalleuchten finden beispielsweise als Blinkleuchten zur Richtungsanzeige oder Bremsleuchten Einsatz.The invention relates to a colored radiating signal light according to the preamble of the claim. Such signal lights can be found, for example Use as flashing lights to indicate direction or brake lights.

Insbesondere dann, wenn derartige Signalleuchten als Eckleuchten angeordnet sind, also gleichsam in zwei zueinander senkrechten Richtungen strahlen, oder wenn sie Reflektoren enthalten, besteht die Gefahr, daß beim Einfall von Sonnenlicht die Betätigung der Leuchte vorgetäuscht wird, d.h. die Signalleuchte in ihrer vorgegebenen Farbe zu leuchten scheint. Dies gilt auch dann, wenn man die durchstrahlbare, also glasklare oder durchscheinbare, Abdeckung farblos macht.Especially when such signal lights are arranged as corner lights are, so to speak shine in two mutually perpendicular directions, or if If they contain reflectors, there is a risk of exposure to sunlight the actuation of the light is simulated, i.e. the signal light in its specified Color seems to shine. This also applies if you have the radiolucent, ie crystal clear or translucent, makes the cover colorless.

Darüber hinaus ist es in vielen Fällen aus stilistischen Gründen unerwünscht, die gewünschte Farbe der Signalstrahlung durch entsprechende Einfärbung der Kappe zu erzielen.In addition, in many cases it is undesirable for stylistic reasons the desired color of the signal radiation by corresponding coloring of the cap to achieve.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, eine Signalleuchte der eingangs beschriebenen Art zu schaffen, bei der bei einfallender Sonnenstrahlung der Anschein der Betätigung der Leuchte vermieden und die Färbung der Signalstrahlung durch Mittel erzielt ist, die dem Betrachter bei abgeschalteter Leuchte nicht als farbige Teile erscheinen. Die Lösung dieser Aufgabe soll ferner mit möglichst geringem Aufwand erzielt werden, da es sich um Massenprodukte handelt, und sie soll die Strahlungsintensität zumindest nicht in störendem Maße verringern. Die erfindungsgemäße Lösung dieser Aufgabe ist gekennzeichnet durch die Merkmale des Patentanspruchs.The invention is accordingly based on the object of a signal light to create the type described above, in the case of incident solar radiation the appearance of actuation of the light is avoided and the coloring of the signal radiation is achieved by means that the viewer when the lamp is switched off as colored parts appear. The solution to this problem should also be as low as possible Effort can be achieved because it is a mass product, and it should reduce the radiation intensity at least not to a disruptive extent. The inventive solution to this The task is characterized by the features of the claim.

Die erfindungsgemäße Signalleuchte zeichnet sich also durch einen besonders einfachen Aufbau aus, der auch keinerlei thermische Probleme mit sich bringt. Die erfindungsgemäße Konstruktion erfordert auch keinerlei Reflektor in der Signalleuchte, sondern lediglich in Strahlungsrichtung vor der stets erforderlichen Lampe ein Filter zur Erbeugung der gewünschten Farbe der Signalstrahlung, das innerhalb des undurchsichtigen, dunklen Gehäuses liegt, sowie in Strab1ungsrichtung vor dem Filter eine Fresnellinse.The signal light according to the invention is thus characterized by a particularly simple structure, which also does not cause any thermal problems brings. The construction according to the invention also does not require any reflector in the signal light, but only in the direction of radiation in front of the always required Lamp a filter to diffract the desired color of the signal radiation that is inside of the opaque, dark housing and in front of the Filter a Fresnel lens.

Ein Ausführungsbeispiel der Erfindung wird in folgenden anhand der Figur erläutert, die einen Horiontalschnitt durch die vordere linke Kante eines Kraftfahrzeugs zeigt.An embodiment of the invention will be described in the following with reference to Figure illustrated showing a horizontal section through the front left edge of a Motor vehicle shows.

Von dem eigentlichen Fahrzeug sind lediglich der vordere Karosseriebereich 1 und der seitliche Karosseriebereich 2 angedeutet. In die Karosserie eingesetzt ist die allgemein mit 3 bezeichnete Signalleuchte, die als wesentliche Bestandteile das aus dnnklem, undurchscheinbaren Material bestehende Gehäuse 4, das die Lampenfassung 5 aufnimmt, innerhalb des Gehäuses das hier gelbe Filter 6 und in Strahlrichtung vor diesem die Fresnellinse 7 aufweist; den äußeren Abschluß der die Lampe 8, das Filter 6 und die Fresnellinse 7 aufnehmenden Kammer 9 bildet die Abdeckung 10 aus einem farblosen, beispielsweise glasklaren oder durchscheinenden Material.Only the front body area is of the actual vehicle 1 and the side body area 2 indicated. Inserted into the body is the signal lamp, generally designated 3, which is an essential component the made of thin, opaque material housing 4, which the lamp socket 5 receives, inside the housing, the here yellow filter 6 and in the direction of the beam in front of this has the Fresnel lens 7; the outer end of the lamp 8, the The filter 6 and the chamber 9 accommodating the Fresnel lens 7 forms the cover 10 a colorless, for example crystal clear or translucent material.

Unabhängig von der jeweiligen Stellung des Betrachters und dem Einfallwinkel der Sonnenstrahlung kann bei ausgeschalteter Lampe 8 für den Betrachter nie der falsche Eindruck erweckt werden, als emittiere die Lampe gelbe Strahlung. Dies gilt auch deshalb, weil in der Leuchte kein Reflektor angeordnet ist.Regardless of the position of the observer and the angle of incidence the solar radiation can never the viewer when the lamp 8 is switched off the false impression that the lamp emits yellow radiation. this applies also because there is no reflector in the luminaire.

Wie auch aus dieser Beschreibung eines Ausführungsbeispiels folgt, stellt die Erfindung eine konstruktiv besonders einfache, daher sowohl wenig störanfällige als auch preisgünstige Lösung des oben definierten Problems dar, die dem Konstrukteur bzw. dem Stilisten weitgehende Freiheit hinsichtlich der Gestaltung der Leuchte beläßt und keine Probleme hinsichtlich der Beherrschung der in der Lampe erzeugten Wärme sowie der Strahlungsintensität aufwirft.As follows from this description of an exemplary embodiment, the invention provides a structurally particularly simple, and therefore not very susceptible to failure as well as an inexpensive solution to the problem defined above, which the designer or the stylist extensive freedom in terms of the design of the lamp leaves and no problems with the control of those generated in the lamp Heat as well as the radiation intensity raises.
