Definitions

  • the invention relates to a lighting device for illuminating interiors in buildings or outdoor facilities.
  • the lighting device can be designed as a linear luminaire, and accordingly has a narrow, elongated shape.
  • Such linear luminaires are designed, for example, in the form of neon lamps with tubular lamps or, more recently, with LED lamps in tubular form.
  • an LED lighting device is known. From the US 2015/0029708 A1 a lighting system with changeable light emission characteristics and a lamp holder suitable for this purpose are known. From the US 5,222,799 A a strip-shaped lighting device for stairwells is known. From the DE 15 89 250 A1 a tunnel lighting system is known. From the US 2011/0037411 A1 decorative cladding with integrated lighting is known. From the US 2014/0293611 A1 a holding device for a corner lamp is known. From the US 7,997,043 B1 a system and a method for the installation of a decorative covering are known.
  • the invention has for its object to provide a lighting device with which the lighting of interiors in buildings, outdoor facilities or other objects while still simple installation is more stylish possible.
  • the lighting device has the advantage that it can be constructed in a very simple manner and requires only a few elements, in particular the lamp holder and the lamp cover and, of course, a lighting element as a light source for emitting light.
  • the luminaire holder which can be provided as a separate part, allows simple and quick attachment in the essentially rectangular corner area.
  • the lamp cover can then be attached to this lamp holder, which is already attached in the corner area, e.g. by screwing it on.
  • the lamp cover can be set up for form-fitting attachment to the lamp holder.
  • the luminaire cover can be snapped onto the luminaire holder in a simple manner by means of the first and second latching elements, which will be explained below. No tools are required for this.
  • the assembly can be done easily and quickly by hand. Disassembly is also easily possible.
  • the lighting device is set up for mounting in a corner area, it can be accommodated in a space-saving and optically advantageous manner.
  • a stylish lighting effect can be achieved, for example in the manner of a light-emitting stucco decoration in a corner area of a room.
  • the lamp holder can be designed as a thin folded sheet.
  • the lighting element of the lighting device usually an electrically operated lighting element such as an LED strip or an LED tube, can be part of the lighting device or can be provided separately, for example in such a way that the lighting element is selected by the user as required or is replaced in the event of a defect.
  • the receiving space for receiving the lighting element is advantageously longer than its width and height, i.e. there is a recording space with a comparatively large length in comparison to the other dimensions.
  • the receiving space can advantageously be at least five times as long as it is wide and / or high.
  • the lamp cover has at least one first latching element which is set up to engage behind a first fixing element of the lamp holder, and / or the lamp cover has at least one second latching element which is set up to engage behind a second fixing element of the lamp holder ,
  • the luminaire cover is developed by the first and / or second latching element for easy, form-fitting attachment to the luminaire holder.
  • This also includes the possibility that the lamp cover is attached to the lamp holder in a non-positive manner.
  • the luminaire cover can be used as a universal luminaire cover for both non-positive and positive locking types in order to fix the luminaire cover to the luminaire holder.
  • a first wing of the lamp holder which has the first fastening surface, has at least one form-fitting first fixing element and a second wing of the lamp holder, which has the second fastening surface, has at least one form-fitting second fixing element.
  • the engagement of the first fixing element by the first locking element or the second fixing element by the second locking element includes that at least part of the respective locking element is arranged behind the respective fixing element in the direction in which the lamp cover is placed on the lamp holder, in the sense of an undercut. In this way, the lamp cover is held securely on the lamp holder and cannot fall down.
  • the first locking element engages behind the first fixing element and the second locking element the second fixing element. This can be done in any order or at the same time.
  • the first fixing element, the second fixing element, the first locking element and / or the second locking element can be designed as continuous locking elements or fixing elements in the longitudinal direction, or they can have interruptions, so that several individual fixing elements or locking elements are thereby formed.
  • the lamp cover can be displaceable in the longitudinal direction of the lighting device relative to the lamp holder.
  • the at least one first latching element and / or the at least one second latching element has at least one bevel at the free end.
  • an insertion bevel of the latching element can be provided for engaging behind the respective fixing element assigned to the latching element, so that the latching element can be guided past the fixing element more easily, in particular if the lamp holder is already installed in the corner area and between the respective fixing element and the assigned corner area. Only a small gap remains on the surface.
  • the bevel can in particular be on the inside of the lighting device, i.e. facing the recording room.
  • the luminaire holder and thus the entire lighting device can also be mounted in corner areas that are not exactly right-angled without any special adjustment work, e.g. because two adjoining walls or a wall and the ceiling of a room have slight deviations from the right-angled shape or have unevenness ,
  • the lamp holder can adapt better to such irregularities. It is advantageous if the lamp holder is made of thin sheet material, for example thin metal (sheet metal) or thin plastic.
  • the lamp holder can be provided by folding from a metal sheet.
  • the lamp holder can also be made from an extruded profile.
  • an angle of more than 90 degrees and / or an angle of less than 180 degrees is formed in the receiving space between the first and the second base section.
  • the angle at more than 90 degrees, e.g. 95 or 100 degrees, the aforementioned flexible adaptability of the lamp holder to irregular corner areas is further promoted, moreover, the first and the second wing of the lamp holder do not lie over the entire surface of the respective first and second corner area surfaces. Due to the design of the angle with less than 180 degrees, the lighting device according to the invention is particularly suitable for mounting in inner corner areas of rooms or other objects, i.e. for mounting at an interior angle.
  • the first wing is connected to the second wing via an essentially flat connecting section.
  • the connecting section connects the first and the second base section to one another.
  • the lamp holder has a polygonal angled shape in the profile cross section. This is conducive to the fact that the lamp holder can be manufactured easily and that it can be easily installed in a corner area.
  • the connecting section may be angled with respect to the first and / or the second base section, e.g. angled symmetrically.
  • the connecting section at the same time forms a fastening surface for the at least one lighting element of the lighting device.
  • the lighting element can be easily fixed in the receiving space and can also be exchanged in a simple manner.
  • the connecting section and thus the entire lamp holder can also be used as a heat sink for the lighting element.
  • the lamp cover and / or the lamp holder are mirror-symmetrical to a plane of symmetry.
  • This is conducive to an appealing appearance of the lighting device and is accordingly advantageous to a provide stylish lighting by the lighting device.
  • the plane of symmetry can be arranged, for example, as a bisector between the first and the second wing of the lamp holder.
  • This also creates an advantageous possibility of combining the lighting device according to the invention in the manner of T-connections, for example in room corners in which, for example, two walls and the ceiling of a room meet.
  • the lamp cover is matted and / or colored and / or light-scattering on at least one surface.
  • the lamp cover can have an outer surface that points away from the lamp holder and is matted. In this way, unwanted reflections on the lamp cover are minimized.
  • the inside surface of the lamp cover can also be matted.
  • the lamp cover can be colored, e.g. dyed through in the material of the lamp cover.
  • the lamp cover can be light-scattering, e.g. by means of a corresponding light-scattering structuring of the outer surface and / or the inner surface, or by means of additives present in the volume of the lamp cover, which have a light-scattering effect.
  • the lamp cover completely covers the lamp holder in the assembled state. This has the advantage that the lamp holder is then not visible, at least as far as the lamp cover is only partially transparent, e.g. because it's matted. This is favorable for an attractive appearance of the lighting device.
  • the lamp cover is formed from at least one strand-shaped plastic profile. In this way, the lamp cover can be produced inexpensively. In addition, it is easily possible to provide the lighting device in different lengths, since the lamp cover can be provided by cutting off correspondingly long pieces from the strand-shaped plastic profile as required.
  • the lamp cover can also be manufactured using at least one additive manufacturing process, e.g. through 3D printing. In this way, a particularly flexible design of the lamp cover that is adapted to the respective application can be generated in a simple manner. It is e.g. possible to adapt the shape of the luminaire cover to existing stucco moldings or room designs.
  • the lamp cover has a light-emitting surface through which the light emitted by the at least one lighting element arranged in the receiving space can be emitted to the outside, i.e. to the outside environment of the lighting device.
  • the light emission surface can extend over the entire luminaire cover or only over a part of the luminaire cover.
  • the first and the second latching element can no longer form part of the light radiation surface, at least when the lamp cover is mounted on the lamp holder, since light radiation can also be prevented by the overlap between the respective latching element and the associated fixing element.
  • the lamp cover is designed in the manner of a stucco strip at least in the area of the light emission surface.
  • a glowing stucco bar can be provided.
  • the lighting device can be designed particularly stylish.
  • the lighting device is then particularly suitable for lighting interiors with a special ambience, e.g. in bars, restaurants, hotels, but also in stylishly furnished apartments.

  • the first fixing element and / or the second fixing element is designed as a tab angled in the direction of the interior of the lamp.
  • the tab can form a stop for the lamp cover, e.g. a stop for the first or second locking element of the lamp cover.
  • the first fixing element is designed as a groove-shaped groove, the open side of which faces away from the first wing
  • the second fixing element is designed as a groove-shaped groove, the open side of which points away from the second wing.
  • the channel-shaped groove can be used as a fixation for the lamp cover, e.g. in that an end region of the profile of the lamp cover comes to rest in the groove-shaped groove.
  • the first or second locking element of the lamp cover can come to rest in the groove-shaped groove.
  • the groove-shaped groove thus also forms a stop for mounting the lamp cover on the lamp holder.
  • the lighting device can be endlessly strung together in the longitudinal direction with one or more other similar lighting devices, only one butt joint being formed between two lamp covers.
  • the lighting device can be put together to form larger lighting fixtures in the sense of a modular concept or a modular system. To this In this way, even very large interiors or almost any outside areas can be illuminated.

  • a lamp cover which consists of a plurality of lamp cover segments arranged at an angle to one another and connected to one another is formed, which are placed on the lamp holder.
  • other forms of the lighting device than the linear luminaire mentioned at the outset can also be realized.
  • an essentially rectangular or square shape or other other polygonal shape of the lighting device can be realized in this way.
  • the individual lamp cover segments can each be sections of the material of the lamp cover, as described in this application.
  • a lighting device with the features according to the invention can be installed in a piece of furniture, as will be explained below.
  • the lamp cover from the plurality of lamp cover segments can then be placed on the lamp holder, in particular in the form of an already prepared structural unit. This simplifies the installation of the lamp cover on the lamp holder.
  • the lamp cover segments are prepared by miter cuts and are connected flush to one another at the cut surfaces of the miter cuts to form the essentially ring-shaped lamp holder. In this way, a favorable overall optical appearance of the lighting device is achieved. In addition, unwanted light radiation from otherwise occurring gaps between the lamp cover segments can be avoided.

  • the groove-shaped groove 252 serves to receive the end bevel 323 of the second latching element 322. In this way, the lamp cover 3 is also mounted and fixed on the other side on an end region of the lamp holder 2.
  • the Figure 4 shows in the area A with dashed lines an embodiment of the trough-shaped bevel, which can be produced, for example, by soldering or welding a strip of material.
  • An alternate embodiment of the trough-shaped groove 252 is shown in a region B shown separately with dashed lines. It can be seen that the groove-shaped groove 252 can be provided by repeatedly folding the end region of the sheet metal material of the lamp holder 2.
  • the illustrated embodiment of the lighting device is particularly suitable for attachment to pieces of furniture.
  • the lighting device is attached to the first corner area surface 11 and the second corner area surface 12 by first fixing the lamp holder 2 to these corner area surfaces 11, 12 or the associated walls by means of fastening elements 7.
  • the fastening elements 7 can be designed, for example, as a screw, nail, rivet or the like.
  • the lamp cover 3 can be attached to it.
  • the Figure 4 shows an embodiment in which the lamp cover 2 is fastened on one side by a fastening element 7, for example a fastening element 7 of the type described above.
  • a form-fitting fastening is carried out without additional fastening elements by inserting the latching element 322 into the groove-shaped groove 252.
  • the Figure 5 shows in the lower area a piece of furniture, for example a mirror with a mirror surface 8, which has a body through which the essentially rectangular corner area 1 is formed.
  • This essentially rectangular corner area 1 extends over four sides, ie in this case there are four first corner area surfaces 11 and a second corner area surface 12, which forms a common rear side of the piece of furniture.
  • a lighting device according to the invention is now to be attached to this body of the piece of furniture.
  • respective sections of lamp holders 2 are first fastened in the inner corner regions, for example by means of the Figure 4 Fasteners explained 7.
  • a lamp cover 9 is produced, which is formed from a plurality of lamp cover segments 3, each lamp cover segment 3 being able to correspond to one of the lamp covers 3 described above, at least in terms of the profile shape.
  • the individual luminaire cover segments are prepared with miter cuts at their ends and are joined together flush on these cut surfaces of the miter cuts, for example by gluing and / or welding.
  • a one-piece lamp cover 9 is prepared as a structural unit. This unit has an inner Opening 90 through which the mirror surface 8 is visible when used with a mirror.
  • This lamp cover 9 is now inserted into the recess of the prepared body of the piece of furniture and attached to it, for example in the Figure 4 Art.
