Description

furniture board

Description: The invention relates to a furniture panel with at least one material panel - at least one on the material panel, for. B. attached to a narrow surface of the material plate edge strip, z. B. from at least partially transparent material and at least one electrical function band, z. B. a (flexible) light strip, in particular LED strip, which z. B. for

Backlighting of the edge strip in a plate in the material, z. B. the narrow surface introduced and covered by the edge strip groove is arranged. The term furniture panel includes in the invention not only plate-shaped components of furniture, eg. As kitchen furniture, but also other plate-shaped workpieces of the furniture and construction industry, especially countertops (eg., Kitchen worktops, table tops or the like). Such furniture panels are made on the basis of material plates, the z. B. are formed as wood-based panels. It may be z. B. to chipboard, fiberboard or the like. The material plates can also be used as composite panels, z. B. wood-plastic composite panels may be formed. The narrow surfaces of such material plates are clad in the usual way with edge strips, which are also referred to as furniture edges, edge bands or edges. The attachment of the edge strip on the respective material plate is z. B. in a conventional manner by means of hot melt adhesives. The edging strips can also be used in the course of production with a Melting layer or functional layer are provided, which is then melted during processing with suitable sources (eg., Laser radiation, hot air, plasma, microwaves or the like). In the context of the invention edge strips are used, which are at least partially transparent. Such edge strips are z. As known from EP 0 857 442 A2, they are also referred to as 3D edges. In practice, there is the need to illuminate the area of the edge strips of furniture panels or to provide with lighting devices, so that the "glowing" edge strips themselves serve as illumination of the narrow surfaces of the furniture panels. For this purpose one knows "backlit" edge strips.

So z. B. from DE 20 2010 000 342 U1 a generic furniture panel of the type described above, in which at least one narrow side of the furniture panel has a groove in which a lighting device is arranged with light sources. The lighting device may, for. B. are formed by an LED strip, which is inserted into a groove in the narrow side. This groove is then covered after inserting the lighting device with the edge strip, so that the edge strip is backlit by the bulbs. DE 20 2014 103 706 U1 also describes a furniture panel of the type described above, in which also in a groove in the furniture plate bulbs, z. As light-emitting diodes is used to backlight the edge band. The edge strip or the edge band has a strip body of at least one base material, for. As thermoplastic, on, in the strip body several slats are integrated, which are distributed over the width of the bar or the strip body and extend in the longitudinal direction of the bar. In this case, the slats extend over at least part of the thickness of the strips body and they are arranged obliquely at a predetermined angle to the strip base. The last back can be provided with a decor in principle. However, there is also the possibility that through this "partially transparent" bar, the view of the underlying furniture plate remains free, or the back decor is "partially transparent", so that a backlighting of the edge strip is done.

The furniture panels with backlighting described in the prior art are basically capable of further development in terms of their production or assembly and the visual appearance. - This is where the invention starts. The invention has for its object to provide a furniture panel with backlit edge strip of the type described above, which is characterized by simplified production and / or an improved visual appearance. To solve this problem, the invention teaches in a generic furniture panel of the type described above, that the light strip (or another electrical function band) is attached to a cross-sectionally U-shaped carrier profile. Such a carrier profile is preferably made of plastic. It has (at least in the mounted state in the furniture panel) in cross section on a base leg and two side legs. The light strip is then arranged in the spanned by the base leg and the side legs of the inner space of the carrier profile and preferably attached to the base leg. In which The light strip is preferably an LED strip. Such LED strips are known as rod products or preferably rolls from the prior art. As a rule, a plurality of light-emitting diodes (and further electronic components or conductors) are arranged on a base strip of such an LED strip. According to such a luminous band, z. As LED tape, now no longer attached directly to the bottom of the groove, but "first" on a support profile which is fixed in or on the groove / furniture panel. With the help of such a carrier profile, to which the LED strip is already attached (pre-mounted), can be a total of simplify the manufacture of the furniture panel or attaching the LED strip in the groove and improve. So it is z. For example, it is not absolutely necessary to fix the LED strip in the groove before attaching the edge strip, but in the context of the invention it is possible first to mount the edge strip which covers the groove and then the support profile can already be attached to it Insert the attached light strip along the longitudinal direction into the groove. Basically, however, the invention also encompasses furniture panels in which first the carrier profile with the light strip attached thereto is fastened in the groove and then the edge strip is mounted. The carrier profile is in the context of the invention, at least in the mounted state, that is, after mounting in the groove, in cross-section (substantially) U-shaped. It is within the scope of the invention that the carrier profile is produced directly as a U-shaped carrier profile (eg by extrusion) and that the light strip is introduced into this U-shaped carrier profile, for. B. glued, is.

However, the carrier profile is particularly preferably formed (initially) by a windable strip-shaped flat profile which is folded in a U-shaped manner at kinks extending in the longitudinal direction. In the course of the Position is therefore initially a flat profile with appropriate desired kinks produced and this flat profile can then fold to form the U-profile at these kinks before it is introduced into the groove of the furniture panel. Such an embodiment has the advantage that the carrier profile first wind up and thus can be very easily transported in long lengths. Particularly preferably, the luminous band is already attached to the windable or wound flat profile, so that the carrier profile can be produced and transported with the light strip attached thereto as a uniform role. In the course of the production of the furniture panel, it is then only necessary to fold the side legs of the carrier profile to form the U-shape, so that the carrier profile with the then resulting U-shaped cross-section and the already mounted LED tape as intended in the groove Fix furniture plate.

Plastic profiles in the embodiment as flat profiles with longitudinally extending kinks are known from practice. They are z. B. as edge strips for the covering of profiled plates, z. B. used for cladding of Türfalzprofilen or the like and marketed in practice under the keyword "folding edge". In the context of the invention can be used in the production of the carrier profile according to the invention on the findings in connection with such plastic profiles. So have the carrier profiles as kinks z. B. extending in the longitudinal direction grooves or notches, which are introduced to form thickness-reduced areas in the profile. It is preferably carrier profiles of thermoplastic material, which are preferably formed as extrusion profiles and thus produced by plastic extrusion. The kinks (for example thickness-reduced regions) can be introduced directly during extrusion or else subsequently by appropriate machining. Alternatively, however, a carrier profile made of a different material, for. B. made of metal or a hybrid material or composite material, for. B. come a metal-plastic composite material used. In particular variants with or made of metal may be advantageous for an improved heat department.

It is basically within the scope of the invention that the groove in the conventional and known from the prior art manner in the material plate, for. B. is introduced into the narrow surface of the material plate / is, in particular by machining. In this case, the groove may have a rectangular cross-section, so that the side surfaces of the groove are oriented approximately perpendicular to the base surface of the groove. In a particularly preferred embodiment of the invention, however, one or both side surfaces of the groove at an acute angle of less than 90 °, z. B. 70 ° to 89 °, (preferably 80 ° to 88 °) oriented to the base of the groove, so that z. B. a trapezoidal in cross section groove is realized. The groove is thus preferably introduced with an undercut or undercuts in the material plate, z. B. milled. This causes the groove to taper in cross-section from the base to the edge strip. Such an embodiment initially has the advantage that a relatively wide base area is available for the installation of a correspondingly wide light strip and that nevertheless sufficient material remains laterally of the groove for fastening the edge strip to the narrow surface. In addition, such an "undercut" embodiment has the advantage that the carrier profile can be fastened very easily and reliably in the groove with the attached light strip, because by the undercuts already in the course of insertion or insertion fixation of the carrier profile, without an additional bonding of the carrier profile in the groove is required. In order to there is - as already described - the possibility that first the edge strip (after insertion of the groove) is attached to the narrow surface and that subsequently the carrier profile is inserted with the attached light strip in the undercut groove and thereby fixed.

It is within the scope of the invention that the angle between the side surfaces and the base of the groove (substantially) corresponds to the corresponding angle between the side legs and the base leg of the carrier profile, that is, the angle in the region of the carrier profile can at the angle in the area be adapted to the groove. In the case of a flexible carrier profile which is folded at corresponding kinks (eg notches), the angle can be adjusted by means of a corresponding geometry of the notches. Alternatively, it may also be expedient that the angle in the region of the profile is set to be greater than in the region of the groove, so that then during insertion or after insertion, an outwardly acting force is produced which fixes the profile in the groove. Even with this consideration, the angle in the region of the profile can be adjusted by appropriate geometry of the notches.

It is within the scope of the invention that the light strip is attached to the U-shaped carrier profile in the region of the base leg. Alternatively or additionally, however, the luminous band can also be arranged in the region of a side leg or in the region of both side legs. This applies equally to other light strips and consequently not only to LED strips. Alternatively or additionally, it is possible to provide the areas not provided with a light strip with reflector foils or a reflector material. If z. B. only in the range of one or both side legs a light strip or multiple light strips are provided, then a reflector foil or a reflector material can be used in the region of the base. Conversely, there is also the possibility only in the area of Base surface or on the base leg to provide a light strip or multiple luminescent strips and then in the side of the leg corresponding reflector sheets / reflector materials. Furthermore, it is possible to introduce incisions or comparable recesses into the side limbs, in order to be able to bend the carrier profile and thus allow processing into radii. Incidentally, the use of the carrier profile or carrier strip according to the invention has the advantage that the visual appearance of the backlit edge strip is improved. For in practice there is the problem that when inserting the groove in the material plate (eg., In a chipboard or fiber board) at the transition of the narrow surface in the groove odd edges / contours arise, which are also referred to as "Mäusezähnchen". These lead to an undefined light emission at the edges of the groove, so that the structured transition regions are apparent in the illumination image. By using the carrier profile according to the invention such undesirable effects are avoided because the side legs of the carrier profile are applied to the side surfaces of the groove and they preferably extend directly into the transition region from the groove to the narrow surface and thus directly to the upper edge of the groove that the edge regions of the groove in the mounted state then no longer edges of the optionally torn wood material, but from the side legs of the carrier profile are formed. For preferably, the side legs extend over the entire height / depth of the groove, so that they extend to the edge strip.

Particularly preferably, the electrical function band in the manner described is a light strip, in particular an LED strip for a backlighting of certain areas of the material plate or furniture plate. However, the principle according to the invention, which is based on the use of the U-shaped carrier profile, can alternatively also be realized with other functional bands which can be attached to a U-shaped carrier profile and arranged in or on the material plate in this way. These are typically electronic or electrical functional bands, the other functional elements, such. B. sensors, switches o. The like. May and can be fastened in the manner described in or on plates. In such a case, it is not absolutely necessary that the introduced groove is covered with a transparent edge strip, so that in this case edge strips of non-transparent material are covered by the invention.

Incidentally, the described carrier profile in the manner described is particularly preferably arranged in a groove which is introduced into a narrow surface of the material plate and covered with an edge strip in a conventional manner. In principle, however, the invention also covers embodiments in which the system is not used in the region of the narrow surface, but in the region of the plate surface or plate surface. So z. B. also in the surface, which is usually oriented perpendicular to the narrow surfaces, a groove introduced and arranged therein in the manner described, the carrier profile (with functional band / light strip). Even such introduced into the surface groove can be covered, for. B. with an edge strip, which is made of non-transparent or - in the case of the use of light strips - at least partially made of transparent material. The attachment of the edge strip in the region of the plate surface may, for. B. by means of (double-sided) tape o. The like. Another aspect of the invention relates to the covering of the open ends of the groove and / or the contacting of the electrical function bands, for. B. light bands (preferably LED bands). Thus, the invention proposes that one or more open ends of the covered by the edge strip groove are closed with at least one cap. Such a cap can be detachably attached to the material plate and positively held at this. With the help of such caps therefore a perfect and clean covering of the ends and thus in particular corner regions of the plates can be realized. The caps also allow a low effort also a non-destructive light source change. At the same time a reliable seal against dust, moisture o. The like. Take place. The cover caps can be made of plastic or metal or also of a composite material (eg of plastic and metal). In addition to a positive connection in the sense of a Aufsteckens or clipping an optionally releasable adhesive connection can be realized, for. B. with conventional adhesives. Alternatively or additionally, the cap on its inner surface with sealing means, for. B. be provided with silicone or soft TPE pads. For the design adaptation, the cover caps (outside) can be equipped with a specific surface design or a decorative surface.

With the help of the caps can also be a simple electrical contacting of the arranged in the interior of the groove electrical components, in particular a simple contact with a light strip, z. B. LED band can be realized. The cap may be provided for electrical contacting of the light strip with a contacting device, which is contacted in the course of attaching the cap on or on the material plate with an electrical connection device of the light strip. Thus, in the cap z. B. a (multipolar) plug or a socket be integrated, which can be inserted in the course of attaching the cap in or on a corresponding socket / plug of the light strip. In this way, a simple contact succeeds by attaching the cap, wherein the contacting of the cap then z. B. externally provided with connection cables or can be contacted with connecting cables, so that electrical leads are not led into the groove, but from the outside of the cap can be attached.

Alternatively, it is also possible to use a cap without (special) contacting device, such a cap z. B. with an opening, z. B. may be provided a bore. Through this hole can z. B. a connection cable for the electrical contacting of the light strip are passed, so that z. B. a connector can be plugged directly onto an applied on the LED strip or the light strip contacting device.

Alternatively or additionally, it is possible to use a cap without contacting device and / or without a hole and the electrical conductors which are connected to a light strip, via an adjacent second groove in another area of the material plate, for. B. dissipate to the back of the plate to realize a no or less visible cable feed. For this purpose, a first groove with the light strip can be introduced into a first narrow surface and adjoins a second narrow surface (for example, vertically oriented) which has a second groove, wherein a connecting cable of the light strip arranged in the first groove in the second Passed groove and is guided in a remote from the first groove rear portion of the furniture panel. In this rear area of the furniture panel can then z. B. again be provided a cap z. B. is provided with a hole for taking out the cable. Alternatively or In addition, the cables can also be led out by an introduced into the material plate hole z. B. from a surface (preferably a bottom) of the plate is introduced into the region of the groove. Such a bore is thus in the range of a groove, for. B. in the region of the second groove, introduced into the wood-based panel so that it opens from the surface (eg., From the bottom) through the material of the wood-based panel into the interior of the groove.

Overall, this achieves a simple and perfect contact of the light strip / functional band with electronic components, such. As power supplies and / or DC converters, controls, switches and / or sensors in a hidden or non-visible area.

The invention is not only the furniture panel described, but also a edge set for such a furniture board, such a edge set as a kit of at least one (at least partially transparent) edge strip and at least one (equipped with a lamella) carrier profile. Thus, according to the invention, it is possible to provide the customer (eg furniture manufacturers or furniture board manufacturers) with such a set of edge and carrier profile, wherein the light strip (eg LED strip) is already preassembled on the carrier profile. The edge strip is preferably provided in a basically known manner as a rolled product in a wound state. However, the carrier profile with the light strip attached thereto is particularly preferably made available in a windable embodiment or as a rolled product in a wound-up state. This possibility exists in particular when the carrier profile is first produced as a flat profile with predetermined bending points. According to the invention, the manufacture of the furniture panel or the mounting of the light strip on the furniture panel is also of particular importance. First, it is advantageous if a carrier profile is provided with it already attached light strip available, that is, the light strip (or the light bands) is attached to the support profile before it is mounted on the furniture panel. Of course, the groove is introduced into the narrow surface before the edge strip is attached to the narrow surface. There is the possibility that the carrier profile (with the light strip) is mounted in the groove before the edge strip is attached to the narrow surface. However, it is preferably also within the scope of the invention that first the edge strip is attached to the narrow surface and then introduced the carrier profile (with the light strip attached thereto) in the groove, z. B. is inserted in the longitudinal direction. In particular, in such an embodiment, it is within the scope of the invention that is dispensed with an adhesion of the carrier profile in the groove. The dimensioning of the carrier profile is carried out depending on the desired application, in particular the plate thickness, which corresponds to the width of the edge strip in the finished state. Thus, the width of the base of the groove about 50% to 90% of the plate thickness and the width of the edge strip (in the assembled state) amount. The depth of the groove is preferably 3 mm to 15 mm, z. B. 6 mm to 12 mm.

In the described embodiment with undercut, the width of the exit surface of the groove is less than the width of the base of the groove. Thus, the width of the exit surface of the groove by 5% to 50%, preferably 10% to 40% less than the width of the base area.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. Show it: Fig. 1 shows a furniture panel according to the invention in cross section and

Fig. 5, the furniture panel of Fig. 3 in a modified

Embodiment. In Fig. 1, a furniture panel 1 is shown in a simplified cross section, wherein such a furniture panel consists essentially of a material plate 2, the z. B. is formed as a wood-based panel, and at the narrow surface 3, an edge strip 4 is attached. In the course of the production of the furniture panel, such an edge strip 4 is usually attached with excess to the narrow surface 3 and then (eg by machining) adapted to the thickness D of the furniture panel 1, so that the width of the edge strip 4 in the state shown in Fig. 1, the thickness D of the furniture panel 1 and the material plate 2 corresponds. One or more surfaces 1 1 of the material plate may be coated in a basically known manner with a decor or the like. Details are not shown in the figures.

The edge strip 4 is formed as at least partially transparent edge strip. In the illustrated embodiment, it is a so-called "fin edge" z. B. from DE 20 2014 103 706 U1 known is. On the one hand, it has transparent regions 4a and, on the other hand, non-transparent regions 4b in the form of lamellae. According to the invention, a backlighting of such edge strip 4. For this purpose, a groove 5 is introduced into the narrow surface 3 of the material plate 2, z. B. by machining. In this groove 5, at least one light strip 6 is arranged for backlighting the edge strip 4. This light strip can be an LED strip. In the illustrated embodiment, a plurality of LED strips 6 (parallel to each other) are arranged in the groove 5. According to the invention, however, these LED strips 6 are not fastened directly to the base surface 5 a of the groove 5, but the light bands 6 are fastened to a separate carrier profile 7, this carrier profile 7 having a U-shaped cross section in the mounted state. The carrier profile 7 thus has a base leg 7a, which is associated with the base 5a of the groove and also side legs 7b, which are associated with the side surfaces 5b of the groove. The light strip or light bands 6 are attached to the base leg 7a of the carrier profile 7. The light bands 6, z. B. LED tapes may be commercially available in a basically known manner. They usually have at least one base band 8, on or on which a plurality of LEDs 9 is attached. Such LED bands are z. B. provided as a roll product, they can be used according to the invention by being attached to the support profile 7 essential to the invention.

Although the carrier profile 7 has in the mounted state shown in Fig. 1 on a U-shaped cross-section. However, it is initially provided as a flat profile according to FIG. 2 available. The carrier profile 7 is thus formed by a windable strip-shaped flat profile, which has kinks 10 which extend along the longitudinal direction of the profile. In this embodiment, the LED strip (or the multiple LED bands) attached. The kinks are formed by thickness-reduced areas, the z. B. caused by the introduction of notches or the like. Consequently, in the illustrated embodiment, the flat profile with the LED strips shown in FIG. 2 is initially made available as a preliminary product, so that it is possible, in particular, to supply this intermediate product in roll form. Subsequently, the flat profile can be buckled in the course of assembly to the predetermined bending points to form the U-shaped cross-section and this U-profile thus created can then be inserted into the groove 5 with the already pre-assembled light bands. There is either the possibility to introduce the U-profile before attaching the edge strip 4 in the groove. Alternatively, however, it is also possible to first attach the edge strip 4 to the material plate 2 and the (folded) carrier profile 7 can then be inserted along the longitudinal direction into the groove 5 and consequently under the edge band 4.

It can be seen that the groove 5 has a deviating from the rectangular shape in the illustrated embodiment, z. B. a trapezoidal cross-section. Thus, the side surfaces 5b of the groove 5 are oriented at an acute angle α of less than 90 ° to the base 5a. This results in that the width B of the base 5a is greater than the width b of the exit surface of the groove 5, so that the groove tapers in cross section from the base to the exit surface and thus undercuts are formed. It should be noted that the angle .alpha. In FIG. 1 is markedly oversubscribed. In fact, the angle α is in practice about 80 ° to 89 °, z. B. 85 ° to 89 °. It can be seen in the figure that the angle α in the assembled state for the carrier profile on the one hand and the groove on the other hand (essentially) is identical, that is, the side legs of the carrier profile lie against the side surfaces of the groove. This can be achieved so that the carrier profile is also equipped in the course of production with an angle α, the Angle α corresponds to the groove, so that the angles are substantially identical to each other. Alternatively, there is also the possibility that the angle α of the (not yet introduced into the groove) carrier profile is slightly larger than the angle α of the groove, so that after insertion an outwardly acting force is generated, the profile in the groove fixed.

In the figures, an embodiment is shown, in which the LED strips 6 are fastened exclusively to the base leg 7a of the carrier profile 7. Alternatively, it is also possible to attach one or more LED strips on one or on both side legs 7b, either in addition to the base leg 7a or as an alternative to the base leg 7a. If z. B. light bands 6 are attached only to the side legs 7b, it may be appropriate to the base leg 7a a reflective material, eg. B. to provide a reflector sheet.

Incidentally, there is the possibility of introducing incisions into the side limbs 7b of the carrier profile from the outside, specifically over the length of the carrier profile, a multiplicity of spaced-apart incisions, so that the carrier profile can be bent. In this way, processing in the range of radii is also possible. This option is not shown in the figures.

This embodiment first of all leads to a simple fixation of the carrier profile 7 in the groove 5, without the need for adhesive bonding. In addition, even with a relatively large width B of the groove in the base surface 5a, a sufficient residual width is provided for the attachment of the edge strip 5 to the narrow surface 3. The use of a U-shaped carrier profile leads to the rest, that in the transition region from the side surfaces 5b of the groove to the narrow surface 3 clean edges for Be provided, so that in particular disturbing effects are avoided by torn transition areas of the wood material.

The illustrated embodiment can be z. B. on a countertop (eg kitchen countertop) or even a table top. So z. B. at a plate thickness D of 38 mm and a corresponding width of the edge strip a groove 5 are introduced, which has a base area with the width B of about 29 to 39 mm and having an exit surface with a width b of about 28 mm. The depth of the groove can in the embodiment z. B. be 10 mm. On both sides of the groove, at least regions with a width of 5 mm are provided in the region of the narrow surface for fastening the edge strip to the narrow surface. The depth T of the groove can z. B. be 10 mm. Another aspect of the invention will be explained with reference to FIGS. 3, 4a to 4c and 5:

In the course of the production of the furniture panel 1 caused by the introduction of the groove 5 end openings and consequently open ends. There is always the possibility to permanently seal them by gluing, z. B. also by an adjoining further edge strip. In the advantageous embodiment according to FIGS. 3 to 5, however, these open ends are closed with cover caps 12 provided especially for this purpose. These cover caps 12 are detachably attached to the material plate 2 and held in a form-fitting manner on this, in cooperation with the introduced groove 5. This results from a comparative consideration of Fig. 3 and 4a to 4c. Because the cap 12 has a covering the groove cover plate 13 and an edge of the cover plate arranged on (partially) circumferential collar 14, which is configured and is dimensioned that it overlaps the material plate and the groove covering the edge strip 4 or surrounds. On the cover plate 13, a plug-in projection 15 is additionally connected inside, z. B. integrally formed, which is U-shaped in the embodiment, said U-shaped plug-in projection is preferably adapted to the geometry of the groove 5. This means that the two side legs of this U-shaped plug projection 15 are oriented at an acute angle to the base of the plug projection 15, wherein the geometric relationships can be realized as well as in the geometry of the groove 5, but such that this plug projection 15th positively engages in the groove. The geometry of the plug projection 15 therefore corresponds identical or nearly identical to the geometry of the carrier profile arranged in the groove, so that the plug projection 15 can be regarded as an extension of the inserted carrier profile 7 without the plug projection 15 necessarily reaching as far as the carrier profile used and this must touch. In any case, can be realized in particular by combination of the circumferential collar 14 with the plug projection 15 a positive connection of the cap 12 on the material plate 2. The cap 12 can be - even if an additional adhesive is used - easily plug in and remove, so that the groove can be made accessible, eg. B. to replace the light strip o. The like ..

According to Fig. 3 there is the possibility that the cap 12 (or the cover plate 13) is provided for electrical contacting of the light strip with a contacting device 16, for. B. a plug or a socket, said contacting device 16 in the course of Aufsteckens the cap 12 on or on the material plate 2 with an electrical connection device 17 of the light strip 6 is contacted. The z. B. in the cap 12 integrated connector 16 engages in or on the socket 17th of the light strip 6 a. The contacting device 16 and / or the Anschlußussein rectification 17 are configured at least two poles. To the contacting device 16 can then z. B. outside a connection cable can be connected.

FIG. 5 shows an alternative embodiment in which a contacting device 16 is dispensed with in the covering cap 12. Rather, the connected to the light strip connecting cable 19 are moved to the rear of the plate. Thus, this embodiment shows a first narrow surface 3, in which in the manner described, the groove 5 is introduced, in which the light strip is arranged. Perpendicular to a second narrow surface 3 'is arranged, which is also covered with an edge strip 4'. Behind this edge strip 4 ', a second groove, not shown, is arranged, which may be the same size as the groove 5 or may be dimensioned differently. In this second groove, the connecting cable of the light strip, which is arranged in the first groove, can now be laid and guided into a rear area of the furniture panel facing away from the first groove 5. In the rear area of the furniture plate is z. B. again a second cap 12 'is provided, which is provided in the embodiment with an opening 18 through which the connection cable 19 may be led out.

In an alternative, not shown, the cable 19 can not be led out through the cap 12 ', but through an introduced into the underside of the plate hole from the (second) groove.

3 and 5 show an example of an embodiment of an edge strip 4, which is only partially transparent, but does not have to be designed as a lamellar edge, but z. B. has a central transparent strip and is not transparent in the lateral edge regions.
