FlutlichtplatteFloodlight panel

Die Neuerung betrifft eine Flutlichtplatte, hergestellt im Unterdruckverfahren, wie sie beispielsweise als Armaturenbrett oder dergleichen, verwendet wird.The innovation concerns a floodlight panel, manufactured in the vacuum process, as used for example as a dashboard or the like.

Die zur Zeit bekannten Ausführungsformen bestehen im allgemeinen aus einer allseitig lichtundurchlässig bedruckten Polymetbylmethacrylat- oder Acrylglas-Platte, auf deren Vorderseite sich Aussparungen für Schriftzeichen und Symbole befinden. Durch Anbringung von Beleuchtungskörpern an beliebigen Stellen wird das Licht in die Platte geflutet und erleuchtet die Schrift.The currently known embodiments exist generally from an all-round opaque printed polymethyl methacrylate or acrylic glass plate, on the front of which there are recesses for characters and symbols are located. By attaching lighting fixtures at any point, the light is in the plate flooded and illuminated the writing.

Diese bekannten Ausführungsformen besitzen erhebliche Nachteile. So besteht die gesamte Oberfläche oder Oberschicht aus Druckfarbe, welche durch chemische und mechanische Einflüsse beschädigt werden kann. Schon Kratzer verursachen, daß Licht aus der Platte durch die Fehlstellen austreten kann. Dadurch wird die Aussage der Darstellung auf der Sichtseite wesentlich verändert,These known embodiments have considerable disadvantages. So there is the entire surface or top layer from printing ink, which can be damaged by chemical and mechanical influences. Already scratches cause that light can escape from the plate through the voids. This makes the statement of the representation significantly changed on the visible side,

Aufgabe der Neuerung ist es, eine Flutlichtplatte zu schaffen, die die genannten Nachteile nicht aufweist und die gegen äußere Beschädigungen aller Art gesichert ist.The object of the innovation is to create a floodlight panel that does not have the disadvantages mentioned and which is secured against all kinds of external damage.

Gelöst wird diese Aufgabe neuerungsgemäß dadurch, daß die Platte in Schichtbauweise gefertigt ist und die Schriftzeichen und Symbole innerhalb der Platte liegen. Die PlatteThis object is achieved according to the invention in that the plate is manufactured in a layered construction and the characters and symbols lie within the plate. The plate

gemäß Neuerung besteht aus einer glasklaren Kunststoff Oberschicht, einer darunterliegenden lichtundurchlässigen schwarzen und die Schriftzeichen und Symbole tragenden Farbstoffschicht, einer transparenten farbigen Schicht, einer Lichtleitsch!J-\t aus Piymethylmethacrylat (PMMA), einer Spiegelschicht aus Kunststoff oder Metall und einer lichtundurchlässigen Deck- oder Abschlu^schicht aus Kunststoff. According to the innovation consists of a crystal-clear plastic top layer, an underlying opaque black dye layer bearing the characters and symbols, a transparent colored layer, a light guide! J- \ t made of methyl methacrylate (PMMA), a mirror layer made of plastic or metal and an opaque top or final layer made of plastic.

Die Lichtleitschicht der Platte ist beidseitig mit Deckschichten kaschiert, weiche liehtundur-chlässig sind, jedoch nicht das durchflutende Licht hemmen. Der Textdruck der Vorderseite liegt unter "einer glasklaren Folie. Sr ist mit c'er Lichtleitschicht thermisch verschweißt. Bestimmte Stellen des Textdruckes sind farblich transparent ausgefüllt und werden durch das in der Platte durchflutende Licht auch im Dunkeln lesbar. Die Ausleuchtung kann mit nur wenigen Lampen an beliebigen Stellen der Platte err folgen.The light-guiding layer of the plate is laminated on both sides with cover layers, which are non-transparent, however, do not inhibit the light flowing through it. The text print on the front is under "a crystal clear film. Sr is thermally welded to the light guide layer. Certain Areas of the text print are filled in with a transparent color and are reflected in the flow through the plate Light can also be read in the dark. The illumination can be achieved with just a few lamps at any point on the plate follow.

Den Unterlagen ist ein Modell (zweifach) beigefügt.A model (in duplicate) is enclosed with the documents.
