Description

Die Erfindung betrifft ein Bedienelement mit Beleuchtung.The invention relates to a control element with lighting.

Bekanntlich weisen Bedienelemente oben Symbole auf, die insbesondere in Kraftfahrzeugen beleuchtet werden müssen, wobei unterschieden wird zwischen Nachtbeleuchtung und Tagesbeleuchtung.As is known, control elements have symbols at the top, particularly in motor vehicles must be illuminated, a distinction being made between night lighting and daylight.

Aus der DE 198 34 374 A1 ist ein Drehknopf eines Steuergerätes bekannt. Zur besseren Ausleuchtung der Skala ist vorgesehen, dass ein Lichtleitkörper mit seinem oberen Umfangsteil in einem transparenten Gehäuseteil endet, das eine von außen sichtbare Skala und einen gehäusefesten, zwischen Skala und Umfangsteil angeordneten weiteren Lichtleitkörper aufweist, der in seinem Lichtgang eine Totalreflexion besitzt.A rotary knob of a control device is known from DE 198 34 374 A1. For better Illumination of the scale is provided that a light guide with its upper peripheral part ends in a transparent housing part, the one from the outside visible scale and a housing-fixed, arranged between the scale and peripheral part has another light guide body, the total reflection in its light path has.

Die DE 195 42 913 C2 offenbart eine beleuchtbare Bedienelementenanordnung. Gewünscht wird eine gleichmäßige Ausleuchtung der Drehknöpfe und der zugehörigen Anzeigesymbole. Geschaffen wird dies dadurch, dass ein jeweiliges Durchführungselement wenigstens im zwischen Frontplatte und Lagerhülse durch einen Lichtkasten hindurchführenden Abschnitt lichtdurchlässig ausgebildet ist.DE 195 42 913 C2 discloses an illuminable control element arrangement. Uniform illumination of the rotary knobs and the associated ones is desired Display symbols. This is achieved through the fact that a respective implementation element at least in between the front plate and the bearing sleeve by a light box passing portion is translucent.

Eine um derartige Bedienelemente vorhandene Korona (Freiraum zwischen Skala und Drehknopf) wird nicht ausgeleuchtet.A corona around such controls (space between scale and rotary knob) is not illuminated.

Die Erfindung stellt sich die Aufgabe, eine konstruktiv einfache Beleuchtung aufzuzeigen, die auch das Ausleuchten der Korona ermöglicht.The invention has for its object to show a structurally simple lighting, which also enables the corona to be illuminated.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. The object is achieved by the features of patent claim 1.

Der Erfindung liegt die Idee zugrunde, einen vorzugsweise nicht bewegten Lichtleiter durch einen umlaufenden Schlitz , in den eine Bedien- oder Frontblende eintaucht, in zwei Bereiche zu unterteilen. Der innere Bereich ist von einem Benutzer einzusehen und stellt die im Nachdesign beleuchtet Korona das. Der äußere Bereich ist durch die Blende verdeckt und leuchtet die aus diversen Symbolen bestehende, um den Drehknopf umlaufende Skala aus.The invention is based on the idea of a preferably non-moving light guide through a circumferential slot into which a control or front panel is inserted, in to divide two areas. The inner area can be viewed by a user and represents the corona illuminated in the post-design. The outer area is through the The cover, which is made up of various symbols, hides and lights around the rotary knob circumferential scale.

Die um den Drehknopf angeordneten Symbole, die im Nachtdesign hinterleuchtet (Suchbeleuchtung) werden, sind beispielsweise in Laser-, in Umspritz- oder in Folientechnik dargestellt und im Tagesdesign durch entsprechende Kontrastbildung mit ihrer Umgebung leicht erkennbar. Die Korona wird als leuchtender Ring um den Drehknopf beleuchtet, der unbeleuchtet nicht oder nur ganz schwer erkennbar ist.The symbols arranged around the rotary knob, which are backlit in the night design (Search lighting) are, for example, in laser, extrusion or film technology shown and in the day design with appropriate contrast formation their surroundings easily recognizable. The corona is a luminous ring around the Illuminated rotary knob that is not illuminated or is difficult to see.

Die Anpassung der Helligkeiten von Skala und Korona erfolgt über lichtstreuende Bestandteile im Lichtleiter, entsprechende Wandstärken im Symbolbereich bzw. durch eine lichtumlenkende Schräge an der Unterseite des Lichtleiters.The brightness of the scale and corona are adjusted using light-scattering Components in the light guide, corresponding wall thicknesses in the symbol area or through a light-deflecting bevel on the underside of the light guide.

Die vorgeschlagene Lösung ermöglicht das gleichzeitig Ausleuchten einer Skala und Korona mit einer Vorrichtung.The proposed solution enables the simultaneous illumination of a scale and Corona with one device.

Anhand einer Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden.
Es zeigt

eine Draufsichtdarstellung eines Bedienelementes,
Figur 2
eine kombinierte Skala- und Koronabeleuchtung.
The invention will be explained in more detail using an exemplary embodiment with a drawing.
It shows
Figure 1
2 shows a top view of an operating element,
Figure 2
a combined scale and corona lighting.

In Figur 1 ist ein in einer Blende 10 oder dergleichen befindliches Bedienelement 1 mit einem Drehknopf 2 in einer Draufsicht dargestellt. Um den Drehknopf 2 ist eine in der Blende 10 integrierte umlaufende Skala 3 mit Symbolen 4 angeordnet. Zwischen den Skala 3 und dem Drehknopf 2 befindet sich eine Korona 5, die nunmehr ausgeleuchtet werden kann. 1 shows an operating element 1 located in a panel 10 or the like shown with a knob 2 in a plan view. Around the knob 2 is one in the aperture 10 integrated revolving scale 3 with symbols 4 arranged. Between the scale 3 and the knob 2 is a corona 5, which is now illuminated can be.

Figur 2 zeigt ein kombinierte Ausleuchtung für die Skala 3 und die Korona 5. Diese gemeinsame Ausleuchtung wird durch einen vorzugsweisen drehfesten Lichtleiter 6 bewirkt, der aus zwei Teilen 6.1, 6.2, einem inneren Teil 6.2 und einem äußeren Teil 6.1, besteht, welche durch einen umlaufenden Schlitz 8 getrennt sind, in die Teile 10.1 der Blende 10 eingreifen bzw. eintauchen. Der Transport des Lichtes einer unter einem Lichtrotor 7 befindlichen Lichtquelle 9 erfolgt durch den Lichtrotor 7 in den oberen Bereich hinein. Dort wird es in den Lichtleiter 6 für die Hinter- bzw. Ausleuchtung für die Skala 3 und die Korona 5 eingekoppelt.Figure 2 shows a combined illumination for the scale 3 and the corona 5. This common illumination is provided by a preferably non-rotatable light guide 6 causes of two parts 6.1, 6.2, an inner part 6.2 and an outer part 6.1, which are separated by a circumferential slot 8, into the parts 10.1 engage or immerse the panel 10. The transport of light one under a light rotor 7 located light source 9 takes place through the light rotor 7 in the into the upper area. There it is in the light guide 6 for backlighting or illumination coupled for the scale 3 and the corona 5.

Zur Verbesserung des Lichttransport zur Skala 3 sowie zur Korona 5 sowie um unterschiedliche Helligkeiten zu schaffen, ist vorgesehen, dass zumindest eine Umlenkschräge 6.3 umfangsseitig am Lichtleiter 6 eingearbeitet ist.To improve the light transport to scale 3 and to corona 5 as well as different ones To create brightness, it is provided that at least one deflection slope 6.3 is incorporated in the circumference of the light guide 6.

Es versteht sich, dass im Rahmen des Erfindungsgedankens Weiterführungen möglich sind. So kann der Lichtleiter 6 mit dem Lichtrotor 7 funktional zusammenwirkend verstellt werden, wobei eine bevorzugte Alternative dann die einteilige Ausführung des Lichtrotors 7 und des Lichtleiters 6 ist.It goes without saying that further developments are possible within the scope of the inventive concept are. The light guide 6 can functionally interact with the light rotor 7 can be adjusted, a preferred alternative then being the one-piece design of the light rotor 7 and the light guide 6.
