Definitions
- the invention relates to an edge banding for a furniture panel with a coupling layer that forms a connecting side.
- the connecting side is designed to be able to be connected to an edge of the furniture panel by means of a material-bonded connecting layer.
- the invention also relates to a piece of furniture with an edge banding attached thereto.
- the invention further relates to a furniture element with an edge banding and a kit for forming such a furniture element.
- Furniture boards for furniture construction are available in various designs. Chipboards are often used that have a decorative top layer on their surfaces, namely on the top and bottom. The edges of the furniture board that are adjacent to the surfaces are usually not coated. In the visible area, these edges are subsequently coated with edge banding to improve the appearance, so that the furniture board has an attractive appearance.
- the coupling layer of the edge banding carries an electroluminescent unit with an electroluminescent layer directly or indirectly on its side facing away from the connection side.
- a lighting function is integrated into the edge banding, which enables the visible side of the edge banding to be illuminated over the entire surface, at least in some areas.
- the electroluminescent unit can be integrated into the structure of the edge banding with a thin layer (for example in the range between 8-15 pm). This does not restrict its flexibility or restricts it only slightly. The edge banding therefore remains flexible enough to be securely attached to curved edges of the furniture panel.
- the electroluminescent unit can be easily electrified, for example with a safe power supply with a low voltage of less than 50V.
- the light emitted by the electroluminescent layer can be emitted on the visible side of the edge banding opposite the connection side. There, the light provides a luminous effect as a design element or it is used for lighting purposes, for example for orientation in the dark.
- the coupling layer is designed in the form of an electrically insulating layer.
- the coupling layer therefore electrically shields the electroluminescent layer in order to prevent malfunction.
- the coupling layer can be designed as a plastic layer, for example as a film (e.g. as a TPU film) or as a printed layer.
- the insulation layer can particularly preferably be produced using a screen printing process.
- the layer thickness of the insulation layer is preferably in the range between 0.01 - 2 mm if it is designed as a film.
- the insulation layer shields the electroluminescent layer from moisture to prevent degradation of this layer.
- the coupling layer has a conductive layer in the form of a back electrode on its side facing away from the connection side, and that the back electrode is electrically contacted with a connection element, wherein the connection element preferably has or forms a plug element of an electrical plug connection.
- the connection element can be used to connect the back electrode to a power supply and to supply the electroluminescent layer with power over the surface via the back electrode.
- the back electrode is preferably designed as a printed layer and can be applied in particular using a screen printing process.
- the electroluminescent unit has a dielectric layer and an electroluminescent layer connected thereto, and wherein preferably at least one of these layers is designed as a printing layer, in particular as a screen printing layer.
- the electroluminescent unit preferably the electroluminescent layer facing away from the connection side
- the front electrode is electrically contacted with a connection element, wherein the connection element preferably has or forms a plug element of an electrical plug connection.
- the front electrode can preferably be designed as a printed layer and can in particular be applied using a screen printing process. The light generated can be coupled out at the front via the transparent or translucent front electrode.
- the front electrode is formed by an ITO layer, which is preferably produced using printing technology, in particular using screen printing.
- An edge banding according to the invention can be such that the front electrode is covered directly or indirectly with an electrically insulating insulation layer on the front side facing away from the connection side, wherein the insulation layer is transparent or translucent and wherein the insulation layer preferably forms the end of the edge banding facing away from the connection side, at least in some areas.
- the front electrode is protected from access by a user by means of the insulation layer.
- the insulation layer protects the electroluminescent layer from moisture in order to prevent degradation of the same. Since the insulation layer is transparent or translucent, the light generated in the electroluminescent layer can be emitted in the direction of the visible side of the edge banding.
- the front insulation layer can be designed as a plastic layer, for example as a film (e.g. as a TPU film), or as a printed layer.
- the insulation layer can particularly preferably be produced using a screen printing process.
- the layer thickness of the insulation layer is preferably in the range between 0.01 - 2 mm if it is designed as a film.
- the insulation layer also shields the electroluminescent layer on the front from moisture in order to prevent degradation of this layer.
- One conceivable embodiment of the invention can be such that the insulation layer is coated with a decorative layer on its side facing the connection side and/or facing away from the connection side, and that the decorative layer preferably has color-filtering and/or color-converting materials.
- the luminous representations on the display side can be designed via the decorative layer. If color-filtering materials are used in the decorative layer, then, depending on the filter, certain wavelengths can be filtered out of the spectrum emitted by the electroluminescent layer.
- the emission spectrum can be influenced using converting materials.
- the color-filtering and/or color-converting materials can therefore be used to design the color of the emitted light according to the user's wishes.
- the phosphors in the electroluminescent layer which are used to generate light, are encapsulated by means of color-converting substances (microencapsulation) in order to achieve a shift in the emitted light.
- An edge band according to the invention can be such that the electroluminescent unit is covered directly or indirectly by an electrically insulating insulation layer on the front side facing away from the connection side, wherein the insulation layer is transparent or translucent and wherein the insulation layer preferably forms the end of the edge band facing away from the connection side, at least in some areas.
- the insulation layer facing away from the connection side thus forms a front-side (flat) end surface of the edge band.
- the front end surface of the edge banding can be illuminated by the electroluminescence unit when installed.
- a preferred variant of the invention can be such that an electrically conductive layer, preferably the electroluminescent unit, in particular the front electrode, the back electrode, the electroluminescent layer, and/or the dielectric layer, is arranged set back relative to the boundary edges running in the longitudinal direction of the edge band.
- the edge band is designed in strip form. When it is attached to a furniture edge, the boundary edges running in the longitudinal direction of the edge band protrude over the top and bottom of the furniture panel. The edge band can then be mechanically reworked on its boundary edges so that they preferably line up with the top and bottom of the furniture panel. The electrically conductive layer is then not damaged because it is arranged set back relative to the boundary edges.
- the electroluminescent unit or at least the electroluminescent layer extends into a transition area of the edge banding which extends in a region parallel to a side surface laterally delimiting the edge band between the front (flat) end surface and the side surface.
- the transition region can be delimited by a convex rounding, for example a transition radius, or a lateral bevel.
- the/an insulation layer which forms the flat front end surface of the edge band facing away from the connection side has a side surface on at least one of its side edges running in the longitudinal direction of the edge band, which at least in some regions has a lateral rounding, in particular a convex rounding, and/or a lateral bevel which encloses an angle with the end surface of greater than 90° and less than 180°, preferably greater than 110° and less than 160°.
- the edge radius of the convex rounding can preferably be selected in the range between 0.3 mm and 3.0 mm.
- the rounding and/or bevel of the edge banding can be completely or partially formed by the front insulation layer.
- the edge banding is selected such that the width of the electrically conductive components is smaller than the thickness of the panel, with at least one of the electrically conductive components, for example the electroluminescent layer, advantageously extending into the transition area.
- the electrically conductive layer is thus also set back from the edge of the furniture.
- sacrificial sections are formed, preferably made of insulating material.
- the sacrificial sections can be at least partially separated in a post-processing step, for example by milling or cutting. If the edge band is designed in such a way that the sacrificial sections are not completely separated, then they form protection for the at least one electrically conductive layer in the area of the longitudinal edges, in particular insulation protection and/or a moisture barrier. In addition, a risk of short circuit is avoided, which arises when, as a result of the During the machining process, the front and back electrodes are brought into contact with each other through deformation.
- the sacrificial section or sections are formed by the insulation layers arranged on both sides of the electroluminescent unit, wherein the insulation layers are materially connected to one another, in particular fused.
- the edge of the furniture can be illuminated close to the edge.
- the electroluminescent layer does not extend all the way to the long side boundary edge of the edge banding, as the rounding or bevel emits the light on the visible side close to the edge.
- the rounding acts similarly to an optical lens.
- a scattered light structure is arranged in the area between the electroluminescent layer and the visible side opposite the connecting side.
- the thickness of the edge banding is in the range between 0.6 and 3 mm, preferably in the range between 0.7 and 2.8 mm.
- Such edge banding is sufficiently elastic and flexible so that it can also be molded onto curved, convex or concave edges of the furniture panel.
- the edge banding has a bending stiffness that allows it to be rolled up in the longitudinal direction into a roll having a plurality of windings, wherein the edge banding preferably has a length of at least 20 m, preferably at least 50 m, then it can be easily handled for assembly purposes. Furthermore, the Edge banding can then easily be applied to convex or concave curved furniture edges.
- the object of the invention is also achieved with a furniture element with a furniture panel which has an edge banding according to one of claims 1 to 18 on at least one of its edges, wherein the edge banding is connected to an edge of the furniture panel by means of the material-bonded connecting layer.
- the material-bonded connecting layer is already applied to the edge banding.
- the connecting layer can be applied during the assembly process and is preferably formed from a duromer.
- a further variant of the invention can be such that the furniture panel has a core which has a decorative layer on its top and/or on its bottom, wherein the at least one decorative layer protrudes laterally beyond the core of the furniture panel, and that the edge banding is at least partially covered by the decorative layer in the area of at least one of its longitudinal boundary edges, wherein it is preferably provided that the decorative layer laterally covers at least one or all of the electrically conductive layers and/or the electroluminescent layer.
- the edge banding is protected laterally by the decorative layer(s). If the decorative layer laterally covers the electroluminescent layer, it can be brought up to the inside of the decorative layer in a protected manner.
- the decorative layer can also serve as access protection in order to prevent lateral access to at least one, preferably all of the electrically conductive layers of the edge banding.
- the object of the invention is also achieved with a kit for forming a furniture element according to claim 19 or 20 with at least one furniture panel and a plurality of edge bandings according to one of claims 1 to 18, wherein the edge bandings have a different width between their longitudinal boundary edges.
- the fitter can then select the appropriate edge banding for the specific furniture panel to be processed in order to achieve the advantageous effects of the invention.
