Description

[0001] The invention relates to a panel for a wall. The invention also relates to a lighting device for the panel.

[0002] The object of the invention is to provide a panel and a suitable lighting device with advantageous properties.

[0003] The problem can be solved by a panel having the features of the first claim and by a lighting device having the features of the dependent claim. Advantageous embodiments are set forth in the dependent claims.

[0004] Further possibilities for solving the problem can be found in the following description and the figures.

[0005] It shows Fig. 1: Wall with panel; Fig. 2: luminous strip; Fig. 3: Lighting device; Fig. 4: Section through panel with lighting device; Fig. 5: Section through lighting device with cap; Fig. 6: Insert part; Fig. 7: Panel with shelf.

[0006] To solve the task, a Fig. 1, panel 1 shown shall be as follows.

[0007] The panel 1 may have at least one groove 2. The one or more grooves 2 may be present in a cover layer 3 of the panel 1. The panel 1 may be intended and configured for attachment to a wall 4 and / or ceiling.

[0008] A light source 5 can be inserted into a groove 2. The light source 5 can be powered by electrical energy. A battery can be present on or in the panel 1, via which the light source 5 can be supplied with electrical energy. The battery can be rechargeable, i.e., an accumulator. The light source 5 can be connected to an electrical cable 6 in order to be able to draw electrical power from an external energy source. The cable 6 can comprise an electrical plug 7 at an external end.

[0009] The luminous element 5 can be an LED, i.e., a diode capable of emitting light. The luminous element 5 can consist of one or more LEDs.

[0010] The luminous element 5 can be removably inserted into the groove 2. The luminous element 5 can then be removed from the groove 2 without causing any damage. The luminous element 5 can preferably be removed from the groove 2 without the use of tools. Following removal, the luminous element 5 can be reinserted into the groove 2 or into another groove 2 of the panel 1.

[0011] The luminous element 5 can be permanently inserted into the groove 2.

[0012] The luminous element 5 can be located in a housing 8. The housing 8 can be glued to the groove 2. The luminous element 5 or its housing 8 can be held in the groove 2 by a positive fit. The luminous element 5 or its housing 8 can be held in the groove 2 by a frictional fit.

[0013] The luminous element 5 can be part of a Fig. 2. The light strip 9 can comprise a plurality of light elements 5. The light elements 5 can be arranged on one side of the light strip 9. The light elements 5 can be equally spaced from one another. Light elements 5 can be present from the beginning of the light strip 9 to the end of the light strip 9.

[0014] The light strip 9 can be located in a Fig. 3 shown in section. The profile 10 can be a housing 8 for a lighting element 5 or be part of a housing 8. The profile 10 can be a rectangular profile or comprise a rectangular profile. The cross section is then a rectangle. The cross section can be a square. A slot 11 can run along the profile 10. The cross section of the profile 10 can then be a rectangle with an interruption due to the slot 11. The slot 11 can run from one end to the opposite end of the profile 10. The slot 11 can be present in the middle of a surface of the profile 10. If a lighting element 5 generates light, the light can be visible through the slot 11.

[0015] A web 12 may be present within the profile 10. The web 12 may connect one side of the profile 10 to another side of the profile 10. The web 12 may contribute to the stabilization of the profile 10. The web 12 may divide the profile 10 into two channels 13, 14. One channel 13 may contain one or more luminous elements 5. The other channel 14 may be used, for example, to house an electrical cable. A battery 15 may be housed in the other channel.

[0016] The web 12 can be arranged below the slot 11. The luminous element(s) 5 can be arranged between the web 12 and the slot 11. The luminous element(s) 5 can be attached directly or indirectly to the web 12. The web 12 and / or the profile 10 can be made of a material that reflects light poorly. For this reason, the web 12 and / or the profile 10 can be made of a light-colored material. The material can be white. The web 12 and / or the profile 10 can be made of a material that is transparent or at least semi-transparent to light.

[0017] The luminous element(s) 5 can be encased by an externally visible profile 16. The externally visible profile 16 can be a second profile that encases the aforementioned profile 10. The externally visible profile 16 can be a rectangular profile. In cross-section, the externally visible profile 16 is then shaped like a rectangle. If the externally visible profile 16 is inserted into a groove 2, at least one side of the externally visible profile 16 can be seen.

[0018] The externally visible profile 16 can be transparent or semi-transparent to light. If a luminous element 5 generates light, this is visible through the externally visible profile 16.

[0019] The externally visible profile 16 may be designed such that light is poorly reflected. The externally visible profile 16 may therefore be made of a dark material, for example, black. The material may be colored accordingly.

[0020] The other profile 10 is then an internal profile 10, which is enclosed by the externally visible profile 10. The light-reflecting properties of the internal profile 10 can be better than the light-reflecting properties of the externally visible profile 10. The externally visible profile 16 can therefore be darker in color than the internal profile 10. This makes it possible to integrate luminous elements 5 or a housing 8 containing luminous elements 5 inconspicuously into a panel 1.

[0021] A plurality of grooves 2 may be present. The externally visible profile 16 and the grooves 2 may be colored the same or substantially the same. Both the grooves 2 and the externally visible profile 16 may therefore be dark, for example, black or brown. Further improved, luminous elements 5 or housings 8 with luminous elements 5 located therein may be inconspicuously integrated into a panel 1 in this manner. Luminary elements 5 and housing 8 may be inserted into a groove 2 such that luminous elements 5 and housing 8 do not protrude from the groove 2, as is shown in the Fig. 4 is shown in section. The luminous elements 5 and the housing 8 can be inserted into a groove 2 in such a way that they are offset inward. This further improves the ability to integrate the luminous elements 5 discreetly into a panel 1.

[0022] The cover layer 3 can be located on a layer 17 of the panel 1. The layer 17 can be designed to absorb sound. One or more additional layers of the panel 1 can be present. It is also possible for the panel 1 to be made from a single piece, i.e., not from multiple layers.

[0023] The externally visible profile 16 can be frosted to further prevent light reflections. Grooves 2 can also be frosted for this reason.

[0024] A profile 10, 16 can be made of plastic. Each profile 10, 16 can be made of plastic. The plastic is preferably not a hard plastic, so that a profile 10, 16 can be easily inserted into a groove 2 with a force fit. The plastic can therefore be a soft plastic.

[0025] A rigid plastic is a plastic that is particularly hard, strong, and durable. These materials are characterized by their high mechanical stability, dimensional stability, and often scratch resistance. Examples of rigid plastics include: polycarbonate (PC), acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC, rigid), polymethyl methacrylate (PMMA, acrylic glass), and thermosets (e.g., epoxy resin, melamine resin). Unlike soft plastics, rigid plastics retain their shape even under stress and are less flexible.

[0026] A soft plastic is a plastic that is flexible, elastic, and often bendable. These materials are less hard than hard plastics and often return to their original shape after deformation. They are frequently used for packaging, hoses, cable sheathing, or seals. Soft plastics are flexible and elastic, often soft or rubbery, and sometimes stretchable and tear-resistant. Examples of soft plastics include: soft polyvinyl chloride (PVC), low-density polyethylene (LDPE), silicone, elastomers (e.g., rubber, TPE - thermoplastic elastomers), and polyurethane (PU). The elasticity of soft plastics is often influenced by "plasticizers." These substances make them bendable.

[0027] There may be one in the Fig. 5, a cap 18 shown in section may be present for a front end of a profile 10, 16. The cap 18 may be placed onto a front end of a profile 10, 16. The cap 18 may close a front end of a profile 10, 16. The cap 18 may comprise a connector 19 which is connected to a front end of a profile 10. The cap 18 may be clamped to a front end of the profile 10. The cap 18 may be detachably or permanently connected to a front end of the profile 10. The cap 18 may be connected to an inner profile 10. The cap 18 may be flush with the circumference of a profile 10, 16. The cross-section of the cap 18 is then equal to the cross-section of the profile 10, 16. The cross-section of the cap 18 can be smaller than the cross-section of the profile 10, 16. The cap 18 then does not protrude laterally relative to the externally visible profile 16.The profile can be the profile 16 visible from the outside.

[0028] The cap 18 may be made of plastic to be electrically insulating.

[0029] The light color of the light source can be at least 5000 K or at least 6000 K or at least 6500 K. The light color of the emitted light can be less than 4000 K or less than 3500 K. This can be achieved by a filter that can change the light color. This can be achieved by a wall or casing that is at least partially transparent to light and consists of a dark material. The casing can be the profile 16 visible from the outside. The dark material ensures that the light color of the emitted light changes in the aforementioned manner when light penetrates the wall or casing from the inside to the outside. The casing can be the profile 16 visible from the outside. The casing can therefore be a filter for light.

[0030] The panel 1 can be an acoustic panel 1. An acoustic panel 1 with grooves 2 on an outer side or in a cover layer 3 is a sound-absorbing element used to improve room acoustics. An acoustic panel 1 can consist of several layers 3, 17, which can be constructed in such a way that sound waves can be effectively reduced. An acoustic panel 1 can have a cover layer 3 with grooves 2. The cover layer 3 or surface of the panel 1 can have regularly arranged grooves 2. The grooves 2 can run parallel to one another. The grooves 2 can be equally spaced from one another. The grooves 2 can serve to break up the sound and / or guide it into the material that may be located behind the cover layer 3.

[0031] The top layer 3 can be made of MDF, plywood, other wood-based materials, or wood. The top layer 3 can be veneered. The top layer 3 can be coated with a decorative layer and / or melamine.

[0032] A carrier layer 17 can be located behind the cover layer 3. The carrier layer 17 can be made of MDF or plywood, for example. The carrier layer 17 can be sound-absorbing. The carrier layer 17 can be perforated or slotted to scatter and / or absorb sound.

[0033] In panel 1 or behind panel 1, i.e. opposite the covering layer 3, an acoustic fleece or a sound-absorbing insulation made of mineral wool such as glass or rock wool, polyester or foam can be present to absorb sound and / or to prevent reflection of sound.

[0034] Felt may be provided. The felt material may be plastic. To conserve resources, the plastic may be recycled. Plastic material may have been processed into fibers through a recycling process. The fibers may then be felted to produce the felt. PET (polyethylene terephthalate) may have been used as the plastic. Felt made from plastic, especially PET, absorbs sound and can be particularly resistant to moisture, mold, and deformation.

[0035] A fleece is lighter and more breathable than felt. Felt is denser and more robust than a fleece and therefore particularly durable. Due to its density and static function and the way it is attached to the wooden slats, a felt can be adjusted so that an insert 20 made of Fig. 6 and connected functional parts are to be made capable of withstanding certain loads (supporting loads, suspended loads) in the long term without deformation

[0036] An acoustic panel 1 can be attached to a wall 4 or ceiling, for example, with screws and, if necessary, dowels, or with the aid of adhesive or double-sided adhesive tape. A rail system can be attached to a wall 4, into which an acoustic panel 1 can be inserted and held. An acoustic panel 1 can be hung into a rail system, for example.

[0037] A panel 1 can be a Fig. 6. The insert part 20 can be inserted or can be inserted into a groove 2. The inserted insert part 20 can comprise a thread 21 accessible from the outside. The thread 21 accessible from the outside can be an internal thread. The insert part 20 can comprise a neck 22. The neck 22 can have the internal thread 21. On its upper side, the neck can have a cross-shaped recess 23 in order to be able to turn the neck 22 and thus the insert part 20 with a screwdriver. Wings 24 can protrude laterally from the underside of the neck 22. The wings can extend along a straight line. The wings 24 can then be inserted into a groove 2. The insert part 20 can then be rotated in order to bring the wings 24 into an area or a recess provided for this purpose below the cover layer 3. The insert can thus be attached to a panel 1.To facilitate this, each wing 24 can have a ramp 25 on one side. The ramp 25 of one wing 24 points in the opposite direction than the ramp 25 of the other wing 24. The ramps 25 are inclined toward the underside and outward in such a way that they can facilitate turning the wings 24 into a recess beneath a cover layer 3.

[0038] The wings may have rounded sides 26. The rounded sides 26 may facilitate screwing in an insert part 20. A rounded side 26 may be a lateral edge section of a ramp 25.

[0039] A pin 27 may protrude from the underside of the insert 20. The pin 27 may be arranged centrally between the wings 24. The pin 27 may, for example, be pierced into a layer 17 of the panel 1. A pierced pin 26 may facilitate a rotational movement of the insert 20.

[0040] In the Fig. 1 shows an insert part 20 fastened in this way.

[0041] An attachment can be screwed to the insert part 20 using a corresponding thread. An attachment can then have a thread that can be screwed into the thread of the insert part 20. The thread of the attachment can be an external thread. Instead of a screw connection, a plug connection can be provided in order to be able to connect an attachment to the insert part 20. Preferably, a connection between the attachment and the insert part 20 is a detachable connection. In particular, detachment is possible without tools. Conversely, the attachment can preferably be fastened to the insert part 20 without tools.

[0042] The attachment can be, as shown in the Fig.7, a shelf 28. The attachment may be a hanging device such as a hook or mushroom, a lamp, a holding device for holding a pot or a vessel, possibly comprising a pot or a vessel, a board, a picture frame, a candle holder, possibly with a candle, or a bowl.

[0043] The invention also relates to a lighting device for insertion into a groove 2 of a panel 1. The lighting device can comprise a lighting strip 9 with lighting elements 5. The lighting device can comprise an externally visible profile 16. The lighting strip 9 can be located within the externally visible profile 16. The externally visible profile 16 can be a filter that can reduce the light color of a lighting element 5 from more than 6000 K to less than 4000 K.
