Description

[0001] The invention relates to a modular illuminated surface element comprising a light box housing, lighting devices, and at least one illuminated transparency arranged on the light box housing. The light box housing is formed from profiles that are connected to each other at their ends. Lighting devices are provided inside the light box housing to illuminate the back of the illuminated transparency.

[0002] Such illuminated surface elements are known in the prior art and are frequently used as advertising media and / or as decorative elements and / or for illuminating rooms or presentation areas.

[0003] Illuminated transparencies are light-transmitting components of a light-emitting surface element that are arranged on the light box housing.

[0004] The illuminated sign can be monochrome or printed with advertising or decorative motifs. The back of the illuminated sign is lit by the lighting devices arranged inside the light box housing, so that either the area surrounding the illuminated surface element is lit or the advertising or decorative element printed on the illuminated sign is particularly emphasized.

[0005] The illuminated surface elements known from the prior art can be mounted on a wall, like a picture, or on a ceiling, or suspended from a wall. Furthermore, illuminated surface elements can also be used as room dividers to structure rooms or presentation areas.

[0006] In practice, the production and installation of a light surface element is very complex, as each light surface element must be individually designed for its specific application.

[0007] The invention is therefore based on the objective of creating a light-emitting surface element that can be manufactured significantly faster and more cost-effectively than embodiments known in the prior art. The assembly and disassembly of the light-emitting surface element should also be significantly simplified and faster. Furthermore, it is an objective of the present invention to provide light-emitting surface elements in which as many components as possible are manufactured in the same embodiment and which can therefore be reused even when the light-emitting surface elements are modified and / or new light-emitting surface elements are manufactured.

[0008] This problem is solved according to the invention with a modular luminous surface element having the features of claim 1.

[0009] Advantageous embodiments and further developments of the invention are disclosed in the dependent claims.

[0010] In the illuminated surface element according to the invention, the light box housing is divided by at least one crossbar. The crossbar is attached to two opposing profiles of the light box housing. The crossbar thus spans an area between the profiles of the light box housing.

[0011] Furthermore, the luminous surface element according to the invention provides for at least two surface elements. It is provided that a control element for the lighting device is arranged on the upper surface of each surface element. At least one lighting device is provided on the side of the surface element facing the luminous transparency. The lighting device is connected to the control element. The control element also includes a connection via which it can be connected to electricity.

[0012] The surface elements can be inserted into the spaces formed by the profiles of the light box housing and the crossbeams. If the illuminated surface element comprises only one crossbeam, two surface elements can be used. With an illuminated surface element that has two crossbeams, three surface elements can be used: one element in the space between the profiles of the light box housing and each crossbeam, and the third element between the longitudinal profiles of the light box housing and the two crossbeams. Larger illuminated surface elements with multiple crossbeams can accommodate a correspondingly larger number of surface elements.

[0013] Since all surface elements have the same structure, they can be pre-produced and kept in stock in large quantities. Furthermore, the surface elements can be used with a variety of illuminated surface elements, even if these have different dimensions. The surface elements are designed so that the control elements for the lighting devices can be interconnected, allowing them to be connected to a single power supply and / or enabling the lighting devices on different surface elements to be switched on or off simultaneously.

[0014] The individual control elements may also include a transformer.

[0015] In a preferred embodiment of the luminaire element according to the invention, fastening devices are arranged on the crossbar. In this embodiment, eye bolts are preferred, which are guided through bores in the crossbar and secured by means of a nut on the underside of the crossbar. Wire ropes can be threaded through the eye of the eye bolt to attach the luminaire element to a ceiling surface. By varying the length of the wire ropes, the position and height of the luminaire element in the room can be continuously adjusted. Furthermore, with this type of fastening, the luminaire element has the visual impression of floating beneath the ceiling.

[0016] In a further embodiment of the invention, the light box housing is composed of several profiles that can be connected to one another by connecting elements. In this embodiment, standardized profiles can also be used to form the light box housing. The profiles of the light box housing have grooves into which the connecting elements can be inserted. The connecting elements can then be fixed to the respective profile on both sides of the connected profiles, thus ensuring the stability of the light box housing.

[0017] Furthermore, illuminated surface elements are frequently requested with optionally rounded or semicircular ends on one or both sides. This provides additional variations beyond the rectangular illuminated surface elements, creating a different visual impression. In these designs, the longitudinal profiles—as with the rectangular illuminated surface element—are arranged parallel to each other. However, the transverse profiles include at least some curved sections. For example, in the version of the illuminated surface element with rounded corners, the transverse profiles of the light box housing consist of two rounded profiles, each connected by straight profiles. In illuminated surface elements with semicircular ends, all transverse profiles are rounded, resulting in a continuous curve extending from the base of the longitudinal profiles.

[0018] For illuminated surface elements with rounded or semicircular end pieces, the surface elements arranged in this area must also be adapted to the shape of the cross profiles of the light box housing. Accordingly, the surface elements in the area of ​​the illuminated surface element's end pieces must be optionally rounded at their corners and / or along their entire length so that they can be connected to the correspondingly shaped cross profiles. Furthermore, it can also be provided that three different versions of surface elements are manufactured: surface elements with rounded corners, surface elements with semicircular shapes, and rectangular surface elements.

[0019] In this embodiment, it is particularly advantageous if the surface elements adjacent to the cross profiles of the light box housing have a shape that completely covers the area between the profiles and the crossbar. In this embodiment, all surfaces of the illuminated sign are illuminated uniformly, and gaps that could negatively affect the visual appearance of the illuminated surface element are avoided.

[0020] A particularly advantageous embodiment of the luminous surface element is one in which all surface elements arranged in the area between the longitudinal profiles and the crossbeams have the same shape and dimensions. This embodiment has the advantage that the surface elements can be mass-produced. The surface elements can be prefabricated and used for luminous surface elements of varying lengths. Each surface element has its own lighting devices and a control unit for the lighting devices, so that the lighting devices of adjacent surface elements can be interconnected via their control elements and supplied with power from a central power source / transformer.

[0021] To increase the stability of the illuminated surface element, a further embodiment of the invention provides that the surface elements are attached to the profiles of the light box housing using fasteners. A preferred embodiment includes bores in both the profiles and the surface elements into which the fasteners can be inserted. In practice, fir-tree rivets have proven particularly effective, as they can be driven in with a small hammer without requiring much force and ensure a secure hold of the surface element to the profiles of the light box housing.

[0022] Furthermore, an embodiment is disclosed in which the light-emitting panel(s) have keders on their lateral edges that can be inserted into a circumferential groove in the profiles of the light box housing. In this embodiment, the light-emitting panels can be easily mounted or replaced without tools. During mounting, the keder is simply pressed into the circumferential groove. For dismounting, the keder can be pulled out of the groove.

[0023] In alternative embodiments of the luminous surface element according to the invention, the light-emitting panels are optionally made of a textile material or a plastic material. Both materials can be easily printed individually and each has a light transmission sufficient to either illuminate the room or to make the advertising or decorative motif printed on the light-emitting panel shine brightly.

[0024] Another advantageous embodiment of the invention is one in which the surface element consists of a composite panel that has an aluminum layer on at least one side. Composite panels have the advantage of being inexpensive to purchase and easy to process. The composite panel has an aluminum layer on one side. The lighting devices are arranged on this side. The light can then be reflected from this layer into the luminous surface element to enable the most uniform and shadow-free illumination possible.

[0025] The same effect can be achieved if the surface element is white on one side. In this embodiment as well, the reflectivity is increased. Furthermore, this white side of the surface element can also consist of a layer of aluminum.

[0026] In an advantageous embodiment of the luminous surface element according to the invention, the lighting devices are formed from strips with LED lights. These strips can be easily cut to size and glued onto the surface element in one or more parallel rows. Since the strips have several LED lights at close intervals, this results in uniform illumination of the luminous transparency without the formation of dark areas or shadows.

[0027] Finally, an embodiment is disclosed in which the control elements for the lighting devices are also glued onto the surface element. This embodiment offers the advantage that the surface elements can be fitted with the control elements very easily and quickly. Furthermore, the control elements can also be easily detached from the surface element if a replacement of the control element is desired or necessary.

[0028] The invention and its preferred embodiments are shown and explained in more detail below with reference to the drawings.

[0029] They show: Fig. 1: The embodiment according to claim 1. Fig. 2: A top view of the luminous surface element according to claim 4. Fig. 3: The cross-section of a luminous surface element according to claim 2.

[0030] The Fig. Figure 1 shows a luminous surface element according to claim 1 in a perspective top view. The drawing shows a luminous surface element with a light box housing on which three crossbeams are attached. The light box housing is rectangular. It is formed from two longitudinal profiles and two transverse profiles arranged parallel to each other. The crossbeams are arranged at right angles to the longitudinal profiles and parallel between the transverse profiles of the light box element. The three crossbeams divide the space inside the light box housing into four equal areas.

[0031] On the top of each truss, a mounting device can be seen, which allows the light panel element to be attached to a ceiling in the room, for example.

[0032] Furthermore, the Fig. 1 Four surface elements in a top view, which are not yet inserted into the luminaire surface element. The surface elements are rectangular and each has the same shape and dimensions.

[0033] Each of the surface elements already has a hole into which, in a subsequent manufacturing step, the cable between the control element and the lighting device located on the underside of the surface element can be inserted.

[0034] The Fig. Figure 2 shows a top view of a light panel element in which the light box housing has rounded cross profiles on both sides. In the illustrated embodiment, the light box housing is formed by several profiles, each of which is connected to the others. In the area of ​​the cross profiles, profiles with curves are arranged in the edge regions, while the further cross profile arranged between these profiles is straight.

[0035] The light surface element thus has a largely rectangular shape with rounded corners.

[0036] The illuminated surface element comprises three crossbeams and four surface elements. A control element for the lighting device is attached to each surface element. One side of the control element has a cable that connects through a hole in the surface element to the lighting device located on its underside. The other side of the control element has a connection for a cable that allows it to be connected to a central transformer or directly to a power source.

[0037] At the in Fig. In the two light panel elements shown, each of the crossbeams has two mounting devices, which allow the light panel element to be attached to a ceiling surface, for example, with a wire or plastic thread. In addition, one mounting device is arranged on the straight profile section of the crossbeam.

[0038] The Fig. Figure 3 shows a cross-section of a light panel element. The crossbar is attached to the longitudinal profile of the light box housing. The profile of the longitudinal profile is clearly visible in this cross-section. It features, in particular, two profile surfaces into which connecting elements for joining it to other profiles of the light box housing can be inserted. On the underside of the profile is a profile surface into which the keder of the illuminated panel can be inserted vertically.

[0039] In the Fig.3 the keder is already located in this profile surface, so that the light-transparent is held in it and stretched to the opposite profile.

[0040] An eye bolt is inserted through a hole in the crossbar and secured to the underside of the crossbar with a nut.
