Abstract

An illuminated tile for floor or wall has a sandwich construction of two outer plates (1) of safety glass an inner luminescent layer with connecting electrodes. The outer surfaces of the tile are surface textured with a non slip relief. The luminescent layer is applied to one plate with an electric contact layer. The second plate is coated with an insulating layer and the second electric contact layer. Suitable luminescent pigments include zinc sulphide with cadmium crystals and silver pigments. The inner layers are protected by a silicon rubber coating around the outer edge of the tile.

Description

Die Neuerung betrifft lichtspendende Fliesen für die Verwendung als Wand- oder Bodenbelag im Gestaltungselement-Bereich. Weitere, noch zu erfassende Gebiete sind die Leuchtreklamen, Signalgebung, Dekorationen, Sicherheits- oder Notbeleuchtungen für den Innen- und Außenbereich – Unterführungen – Durchgänge – Flure – Wohn- und Geschäftsbereiche – Büroräume.The innovation affects light-giving Tiles for use as a wall or Flooring in the design element area. More to be recorded Areas are neon signs, signaling, decorations, safety or emergency lighting for the Indoor and outdoor use - underpasses - passageways - corridors - residential and business areas - office space.

Bekannt sind für die Herstellung von farbigen Leuchten beispielsweise Gasentladungsröhren mit unterschiedlichen Befüllungen und entsprechenden Leuchtstoffen. Diese Leuchtkonstruktionen beinhalten durch die farblichen Emissionslinien der Befüllungsgase sowie anorganischen Leuchtstoffe, dass ein teilweise großes Teil des gewonnenen Lichtes absorbiert wird und verloren geht.Are known for the production of colored lights for example gas discharge tubes with different fillings and corresponding phosphors. These include lighting structures through the colored emission lines of the filling gases as well as inorganic Phosphors that a large part of the light obtained is absorbed and lost.

Ebenfalls sind aus der bekannten Technik der Leuchtdioden (LED-Anwendungen) Bauelemente aus der Halbleitertechnik bekannt, bei der beispielsweise am erzeugten p – n Übergang durch Legierung – Bedampfung unter Schutzgas oder Hochvakuum Elektrolumineszenz am Sperrschichtbereich p – n Übergang entsteht und als Leuchtdiode in Bauteile der unterschiedlichsten elektrischen Geräte und Anlagen verwendet werden.Are also from the known Technology of light emitting diodes (LED applications) Components known from semiconductor technology, for example at the generated p - n transition by alloy - vapor deposition under protective gas or high vacuum electroluminescence at the junction region p - n transition arises and as a light emitting diode in components of the most varied electrical devices and equipment can be used.

Der Erfindung liegt die Aufgabe zugrunde, unter Bezugnahme auf die bisher gebräuchliche farbige Leuchtflächenherstellung Leuchten zu realisieren, die gegenüber den bisher herkömmlichen farbigen Leuchtflächenanordnungen mit besserer gleichmäßiger Oberflächen-Leuchtdichte zu schaffen, für farbige, feste Leuchtflächen in Form von Leuchtfliesen für unterschiedliche Anwendungen im Gestaltungselement-Bereich.The invention is based, below Reference to the previously used colored luminous surface production Realize luminaires compared to the traditional ones colored luminous surface arrangements with better uniform surface luminance to create, for colored, fixed illuminated areas in the form of luminous tiles for different applications in the field of design elements.

Die Aufgabe wird gelöst durch die Schaffung von beliebig geformten Flächen für die Ausgestaltung von bekannten Wand- und Bodenfliesen in gleichen Materialstärken der handelsüblichen keramischen Fliesenformate und gewährleisten eine ebenso sicher Verarbeitung wie diese aus dem Fliesenkeramik-Handwerk bekannt sind.The task is solved by the creation of arbitrarily shaped surfaces for the design of known ones Wall and floor tiles in the same material thicknesses as the standard ones ceramic tile formats and ensure an equally safe Processing like this is known from the tile ceramic craft.

Der Aufbau der lichtspendenden Fliese wird dadurch gelöst, dass eine Schichtenzuordnung in Sandwichbauweise bevorzugt wird aus einem Bestand von zwei ESG-Sicherheitsglasscheiben mit aufnehmender integrierter Elektro-Lumineszenzschicht unter Anordnung und Verwendung von Farbpigmenten sowie in Verbindung mit eingebrachten Farbfolien sowie Steuerungsglieder für die leitenden Verbindungen und den Helligkeitsregelkreis. Dieser regelt die Helligkeit der leuchtenden Fliesen stufenlos über die Versorgung mittels Konverter. Die Farbstellungen und Kombinationen reichen von weiß – gelb – türkis – blau und sind verlegbar in den unterschiedlichsten Fliesenrastern. Die Fliesenleuchtfläche ist beständig gegen mechanische und chemische Einflüsse sowie gegen Wasser geschützt bei einer max. Materialstärke von 10 mm für die Wand- und die Bodenfliese.The construction of the light-giving tile is solved by that a layer assignment in sandwich construction is preferred from a stock of two ESG safety glass panes with a receiving one integrated electro-luminescent layer with the arrangement and use of color pigments and in combination with inserted color foils and control elements for the conductive connections and the brightness control loop. This controls the brightness of the glowing tiles continuously the supply by means of a converter. The colors and combinations range from white - yellow - turquoise - blue and can be laid in a wide variety of tile grids. The tile lighting surface is resistant protected against mechanical and chemical influences as well as against water a max. material thickness of 10 mm for the wall and floor tiles.

Die Neuerung wird im folgenden anhand der Zeichnungen näher beschrieben. In der Zeichnung zeigen 1 eine Draufsicht auf eine beschriebene lichtgebende Wand-/Bodenfliese mit Trägerplatte und der Leuchtfläche (10) mit äußerer Randbegrenzung zwischen Trägerplatte und Leuchtfläche sowie die Schnittausführung A – B der Leuchtfliese.The innovation is described below with reference to the drawings.
