The basic body may be coated with paint layers or films, pref. based on polycarbonate, which may be metallised. ADVANTAGE - Back-lit symbol has uniform transparency.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Bedien-, Dekor- oder Anzeigeelementen mit hinterleucht­ baren, diffus-transparenten Symbolen, bestehend aus einem klartransparenten Grundkörper, der mit einer diffus-transparenten Schicht und einer lichtundurch­ lässigen Schicht versehen ist oder aus einem diffus- transparenten Grundkörper mit einer lichtundurchlässigen Schicht, wobei die lichtundurchlässige Schicht mittels Laserstrahlung zur Erzeugung des Symbols entfernt wird.The invention relates to a method for producing Operating, decorative or display elements with backlighting clear, diffuse-transparent symbols, consisting of a clearly transparent basic body, which with a diffuse-transparent layer and an opaque casual layer or is made of a diffuse transparent body with an opaque Layer, the opaque layer by means of Laser radiation for generating the symbol is removed.

In vielen Bereichen besteht ein Bedürfnis, Gerätetasten und dgl. so zu gestalten, daß sie eine gute Lesbarkeit bei Tag und unter ungünstigeren Lichtverhältnissen, ins­ besondere in der Dunkelheit, aufweisen. Zu diesem Zwecke ist es bekannt, die Bedienelemente mit einer Lichtquelle zu versehen, so daß Licht durch transparente Bereiche der Geräteoberfläche austreten kann. Um Blendwirkungen zu vermeiden und den Geräten ein gefälliges Äußeres zu geben, sind die transparenten Bereiche häufig nicht klar transparent, sondern weisen eine diffuse, milchige Transparenz auf. Dabei können auch unterschiedliche Farben verwendet werden. Der Fachmann kennt diese Ge­ staltung von Bedienelementen unter dem Namen "Nacht­ design".In many areas there is a need for device buttons and the like. In such a way that they are easy to read during the day and under less favorable lighting conditions, ins especially in the dark. For this purpose it is known to use a light source to be provided so that light through transparent areas the device surface can leak. To glare to avoid and the devices a pleasing appearance the transparent areas are often not clear transparent, but have a diffuse, milky  Transparency. It can also be different Colors are used. The expert knows this Ge Design of controls under the name "Night design".

Zur Erzeugung dieses Effektes ist es bekannt, einen klar transparenten Grundkörper aus Kunststoff bzw. Kunst­ stoffolie, zweischichtig zu lackieren, wobei die untere Lackschicht den gewünschten transparenten Farbton auf­ weist, während die obere Lackschicht lichtundurchlässig ist. Zur Erzeugung der Symbole, die transparent er­ scheinen sollen, wird ein Laserstrahl über die Ober­ fläche des Kunststoffteiles geführt. Dieser trägt die lichtundurchlässige Schicht ab und hinterläßt im Bereich des Symbols lediglich die transparente Lackschicht. Obwohl dieses Verfahren flexibel ist und auf jede ge­ wünschte Symbolform eingestellt werden kann, besitzt es jedoch den Nachteil, daß beim Abtragen der lichtundurch­ lässigen Lackschicht die transparente Lackschicht eben­ falls durch die Laserstrahlung geschädigt wird. Dies führt im Symbolbereich zu Stellen unterschiedlicher Transparenz, die den optischen Eindruck des Gerätes be­ einträchtigen.To produce this effect it is known to be clear transparent base made of plastic or art fabric film, two layers of paint, the lower one Lacquer layer the desired transparent color points, while the upper layer of paint is opaque is. To generate the symbols he transparent A laser beam is supposed to shine over the upper surface of the plastic part. This carries the opaque layer and leaves in the area of the symbol only the transparent lacquer layer. Although this procedure is flexible and applicable to any ge desired symbol shape can be set, it has however, the disadvantage that when removing the opaque casual varnish layer, the transparent varnish layer if it is damaged by the laser radiation. This leads to different places in the symbol area Transparency that be the optical impression of the device compromise.

Ferner ist bekannt, bei einem bereits diffus-transparen­ ten Grundkörper auf die entsprechende milchig-transpa­ rente Zwischenschicht zu verzichten. Dies hat jedoch den Nachteil, daß der Grundkörper selbst durch die Laser­ strahlung beschädigt wird.It is also known that the diffuse-transparent one base body on the corresponding milky-transparent to waive the intermediate pension. However, this has the Disadvantage that the base body itself by the laser radiation is damaged.

Weiter ist bekannt, den Grundkörper mit Folien zu be­ schichten beziehungsweise zu kaschieren, die an die Stelle der Lackschichten treten.It is also known to be the base body with foils layer or conceal that to the Step in place of the paint layers.

Es bestand daher die Aufgabe, das oben beschriebene Ver­ fahren so zu verbessern, daß die hinterleuchtbaren Be­ dienelemente eine für den Betrachter gleichmäßige Transparenz aufweisen.It was therefore the task of ver drive to improve so that the back-lit Be controls an even for the viewer Show transparency.

Die Aufgabe wird dadurch gelöst, daß zwischen die dif­ fus-transparente Schicht oder dem diffus-transparenten Grundkörper und der lichtundurchlässigen Schicht eine klar transparente Pufferschicht eingesetzt wird, die zur Erzeugung des Symbols durch Laserstrahlung teilweise abgetragen wird.The object is achieved in that between the dif fus-transparent layer or the diffuse-transparent Base body and the opaque layer one clear transparent buffer layer is used, which for Partial generation of the symbol by laser radiation is removed.

Es hat sich als vorteilhaft erwiesen, eine weitgehend transparente Lackschicht als Pufferschicht für die Laserstrahlung zwischen die abzutragende Lackschicht und die Lackschicht einzubauen, die das Erscheinungsbild des hinterleuchtbaren Symbols bestimmt. Die Klarlackschicht, die eine große Transparenz aufweist, wird nur teilweise von der Laserstrahlung abgetragen, so daß die darunter­ liegende Lackschicht vollständig erhalten bleibt. Zur Abtragung läßt sich vorteilhaft ein NdYAG-Laser mit einer Wellenlänge von 1064 nm oder frequenzverdoppelt mit einer Wellenlänge von 532 nm verwenden. Der NdYAG- Laser wurde vorzugsweise bei Stromstärken <15 A und mit einer Pulsfrequenz von 2 bis 20 kHz, zum Teil auch höher, betrieben. Die Schichtdicke der Lackschichten liegt vorzugsweise im Bereich von 5 bis 25 µm, insbeson­ dere zwischen 10 und 20 µm. Die lichtundurchlässige Decklackierung wird durch die entsprechenden Zusätze bevorzugt schwarz eingestellt. Als Lacksysteme werden vorzugsweise Lacke auf Acrylharzbasis und Ein- oder Zweikomponentenlacke, insbesondere reaktive Systeme, auf Polyurethanbasis und Polyurethandispersionen verwendet. Die entsprechenden Farben werden durch anorganische oder organische Pigmente oder Farbstoffe eingestellt.It has proven advantageous, largely transparent lacquer layer as a buffer layer for the Laser radiation between the paint layer to be removed and to incorporate the lacquer layer, which the appearance of the backlit symbol. The clear coat, which has a high degree of transparency is only partially ablated by the laser radiation, so that the underneath horizontal paint layer is completely preserved. For A NdYAG laser can advantageously be removed a wavelength of 1064 nm or frequency doubled use with a wavelength of 532 nm. The NdYAG Laser was preferred at currents <15 A and with a pulse frequency of 2 to 20 kHz, sometimes also higher, operated. The layer thickness of the lacquer layers is preferably in the range from 5 to 25 μm, in particular between 10 and 20 µm. The opaque Top coat is made using the appropriate additives preferably black. As paint systems preferably acrylic-based paints and single or Two-component paints, especially reactive systems  Polyurethane base and polyurethane dispersions used. The corresponding colors are represented by inorganic or organic pigments or dyes set.

Mit Vorteil lassen sich zur Beschichtung des Grundkör­ pers auch vorgefertigte Folien, die auch metallisiert sein können, verwenden. Besonders bevorzugt sind hierzu Folien auf Polycarbonatbasis.Advantageously, for coating the base body pers also prefabricated foils that are also metallized can be use. Are particularly preferred for this Polycarbonate-based films.

Im folgenden wird die Erfindung anhand dreier Beispiele näher erläutert.In the following the invention is illustrated by three examples explained in more detail.

Bei allen Beispielen wurde ein transparenter Formkörper mit einer weiß-transparenten, darauffolgend einer klaren und einer schwarzen Oberflächenschicht lackiert. Im ersten Beispiel wurden ausschließlich Zweikomponenten­ reaktivharze auf PU-Basis verwendet. Im zweiten Beispiel bestanden die Lackschichten ausschließlich aus Lacken auf Acrylharzbasis. Im dritten Beispiel wurde die Klarlackschicht des ersten Beispiels mit der weißen und schwarzen Schicht des zweiten Beispieles verwendet. Bezüglich der Stromstärke und der Pulsfrequenz ergaben sich die besten Ergebnisse für Beispiel 1 bei 21 kHz und 20 A, für Beispiel 2 bei 18 A und 5 kHz und für Beispiel 3 bei 13 A und 18 kHz.In all examples, a transparent molded body was used with a white-transparent, then a clear one and painted a black surface layer. in the The first example only used two components reactive resins based on PU are used. In the second example the layers of paint consisted exclusively of paints based on acrylic resin. In the third example, the Clear coat of the first example with the white and black layer of the second example used. Regarding the current strength and the pulse frequency the best results for example 1 at 21 kHz and 20 A, for example 2 at 18 A and 5 kHz and for example 3 at 13 A and 18 kHz.
