Description

The present invention relates to a system for forming a so-called light line, in which an elongated, channel-like receiving space is formed, which has a translucent light exit area on one side and in which a plurality of lighting units are arranged.

Light lines, which are the subject of the present invention, represent special cases of so-called light band systems. Such light band systems are widely used in lighting technology because they allow the lighting to be flexibly adapted to external conditions.

Known trunking systems are based on the use of a so-called mounting rail arrangement, which represents the central holder for all other components of the trunking system. Such arrangements consist of individual support rail elements arranged one behind the other, which e.g. are formed from elongated sheet metal profile parts, which are, for example, U-shaped in cross section and open at the bottom, so that they form a longitudinally extending receiving space which is used first of all to arrange the components responsible for the power supply to the light sources of the continuous row system. On the one hand, these are the cables for the power supply and, if appropriate, also for signal transmission, which usually run along the entire arrangement. Furthermore, however, at least the contacting means of light modules to be fastened to the mounting rail arrangement are also accommodated within the accommodation space, and, if appropriate, also associated operating devices such as converters or the like, with the aid of which the power supply provided by the through-wiring is converted into a current suitable for operating the light sources becomes.

In a continuation of the variants described above, the light sources themselves are arranged within the receiving space in a light line and the underside of the mounting rail arrangement is then closed by a translucent cover which forms the light exit element of the light line realized in this way. As a rule, the light exit element should appear uniformly bright and of the same color over the entire length of the system.

For optical reasons, it is not very practical for such a line of light to implement the cover from individual parts arranged one behind the other in the longitudinal direction, since light could leave the system more or less unhindered at the joints and, accordingly, homogeneous light emission can no longer be achieved. In an earlier application by the applicant ( WO 2014/174019 A1 ) is therefore a cover is described, which is made in principle "endless" and is designed such that it can be wound up into a roll for transport. This cover is then arranged in one piece, extending along the entire length of the mounting rail arrangement, so that the optical properties of the system are significantly improved.

From the US 6050700 A discloses an elongated lighting system (light band system) with a housing which is capable of supporting a curved lamp tube. The system is based on one or more non-elastic base plate (s) which have been cut from a (rigid) carrier material so that their shape corresponds to the curvature of the lamp tube.

From the DE 202014101986 U1 ) a light band system is known, the light channel of which consists of two profile parts (4, 5) which should be designed so flexibly that they counteract a suction effect caused by temperature fluctuations and an associated entry of dust and moisture into the receiving space (light channel).

The DE 202009015404 U1 discloses a channel-shaped lighting system for walls and ceilings. In order to achieve embodiments for curved or arched walls and ceilings, a row-based segment-based fastening device is disclosed, the segments being pivotable relative to one another to adapt curved or arched installation openings.

The WO 2016/049168 A1 also shows a lamp arrangement, which consists of two elongated, approximately C-shaped and interconnected half-shells. The half-shells are made of a flexible material and are connected to one another at their edge areas via H-shaped connecting elements.

Another registration ( WO 2015/165852 A1 ) known to the applicant to additionally line the receiving space of a mounting rail arrangement with a longitudinally extending, again preferably integrally formed profile part which can be connected to the cover. The aim of this measure is to create a recording room for the electrical and electronic To create components of the trunking system that is protected as well as possible from external influences, in particular from dust and / or moisture. Since, as mentioned at the beginning, the individual mounting rail elements have only a limited length and, accordingly, a mounting rail arrangement usually consists of a plurality of mounting rail elements joined to one another at the end, gaps or openings inevitably occur at the joints, through which the protection of the components therein from external influences is impaired. According to the applicant's solution mentioned above, this is avoided in that the interior is now additionally lined with a profile part made of a flexible material. Like the cover, this profile part is also advantageously designed such that it can be transported rolled up into a roll.

With the help of the solution described above, a receiving space that is tightly enclosed over its entire length can be created, in which the arrangement of the further components of the light line then takes place, a particular advantage of the solutions known from the applications mentioned being that the exact length of the recording room and thus, for example, the light line can be freely set by the end user. He only has to cut the mounting rails and the profile parts provided to form the receiving space to the desired length on site. However, this in turn means that no end seals of the receiving space can be made at the factory, but this must also be done on site during the final assembly of the system.

A first task underlying the present invention therefore consists in reliably sealing the channel-like receiving space at its end regions.

The object is achieved by a system for forming a light line, which has the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

In the solution according to the invention, provision is once again made in turn to form the elongate, channel-like receiving space by means of elongate, flexible profile parts, which are each at least partially formed from a flexible material in the form of a soft plastic, for example silicone, and are sealingly connected to one another to form the receiving space. End parts are then respectively provided on the two end faces of the receiving space, which are fixed to at least one of the profile parts and seal the receiving space on the end face.

It is crucial for the solution according to the invention that the end parts provided for sealing the receiving space interact in a directly sealing manner with the flexible profile parts forming the receiving space and, moreover, are fixed to at least one of the profile parts themselves. So should the recording space be longitudinal, e.g. due to temperature fluctuations, expand or contract, the corresponding movement is also carried out by the front parts and the permanent frontal coverage of the receiving space is ensured despite everything.

According to the invention, a system for forming a light line is accordingly provided with an elongated, channel-like receiving space, which has a translucent light exit area on one side and in which a plurality of lighting units are arranged, at least two elongated flexible profile parts being provided, each of which is at least partially made of a flexible material are formed in the form of a soft plastic, for example silicone, and are sealingly connected to one another to form the receiving space, and wherein end parts are provided on the two end faces of the receiving space, which are fixed to at least one of the profile parts and each seal the end face.

The end parts are fixed according to the invention in that they are fastened to the at least one profile part by means of a screw connection. For this purpose, it can be provided that the corresponding profile part has channels which extend in the longitudinal direction and are used as screw channels. It is particularly preferred here that the end parts are fixed to one profile part by means of the screw connection and are glued to the other profile part. It is particularly advisable to carry out the adhesive connection with the profile part which forms a translucent cover of the light line.

The end parts themselves are preferably each formed by a base part formed from sheet metal, to which one or more sealing elements made of a flexible material are then attached. The end parts can each have openings for the passage of cables, which are preferably also sealed. The use of a suitable rubber sleeve or comparable measures is recommended for this.

As already mentioned, the two profile parts for forming the receiving space preferably consist of a flexible material, for example of silicone or the like, which also makes it possible for the profile parts and thus the Recording space can have a curvature in the longitudinal direction of the light line. The light band should therefore be able to follow curved surfaces. Another advantage of using the flexible material for the profile parts is that - as described at the beginning - the profile parts can, if necessary, be wound up and easily transported in this form.

Both profile parts can be positively or clamped together to seal in the longitudinal direction of the receiving space in the desired manner. However, it is preferably provided that the two profile parts are connected to one another via web-like carrier elements which extend on both sides along the receiving space and to which the profile parts forming the receiving space are each fastened by clamping. The use of these web-like carrier elements has the particular advantage that they can then be used in a simple manner as central holders for the receiving space. At the same time, however, these support elements will also be used as coupling elements for further supporting structures, with the help of which the light strip is installed. On the one hand, it can be provided that the supporting structure is formed in a known manner by an essentially U-shaped channel, which is formed from one or more sheet metal parts. In this case, it can in particular be provided that the sheet metal parts forming the channel are slotted in a special way, so that they likewise allow the channel to be bent and thus follow curved surfaces. In other situations, on the other hand, it can even be provided that an outer, additional channel surrounding the receiving space is dispensed with and only bow-like holding elements are used, which form the supporting structure. These are then arranged at a distance from one another along the receiving space and coupled to the receiving space via the web-like support elements. It is particularly preferably provided that the bracket-like holding elements allow a certain height adjustability, which makes it possible, for example, to align the light exit surface of the light line flush with the surface of a wall on which the arrangement is mounted.

This flexibility with regard to assembly is made possible in particular by the use of the above-mentioned web-like support elements, which hold the actual channel-like receiving space. This idea can be realized regardless of the manner in which the receiving space is sealed at the end, which is why it is the subject of a further independent claim.

According to this second aspect of the invention, a system for forming a light line with an elongated, channel-like receiving space is proposed, which has a translucent light exit area on one side and in which a plurality of lighting units are arranged, at least two elongated profile parts being provided, each at least partially are formed from a flexible material and are sealingly connected to one another to form the receiving space, and web-like support elements are provided on both sides, along which the profile elements forming the receiving space are clampingly fastened, the receiving space being attached via the support elements is connected to a supporting structure.

Based on Figure 1 the basic application of light lines according to the invention should first be briefly explained. The corner area of a room which is generally provided with the reference symbol 500 is shown schematically, two adjoining walls 501 and the ceiling 502 being recognizable here. In the illustrated embodiment, two light lines 1 are to be realized in this corner area on the two side walls 501, which along their length in one uniform brightness should emit light. The systems used for this purpose, which are described in detail below, are integrated into corresponding elongated installation openings in the walls 501 in such a way that the light-emitting surfaces of the two light lines 1 run essentially flush with the surrounding surfaces of the walls 501. This means that both light lines 1 in principle complete the surface of the respective wall 501, but emit light over the corresponding area. Of course, a further light line could also be implemented in the area of the ceiling 502.

A special feature of the illustrated light lines 1 in Figure 1 consists in the fact that - as can be seen - they follow a curved path. This is not absolutely necessary, but represents a particularly preferred property of the system according to the invention, since in this case there is also the possibility of integrating the corresponding systems into surfaces, that is to say walls or ceilings, which have a certain curvature. In comparison to a rigid system, the possible use is significantly increased and light lines can be implemented in a wide variety of visually appealing variants.

Lines of light that are suitable for following a curved path are already known per se and, for example, in US Pat EP 2 507 543 B1 described by the applicant. In this known embodiment, a substantially U-shaped channel for receiving the light sources is formed by at least sections of one-piece profile body, which are designed in a U-shape and are provided with slots in such a way that they are each bendable about two axes that are essentially perpendicular to one another are. In the first embodiment of the system for forming a light line according to the invention, which is described below with reference to FIG Figures 2 to 10 Correspondingly designed profile bodies are also used, which are then to form the supporting structure for the system as a whole.

In the Figures 2 and 3 these profile bodies provided with the reference number 300 are recognizable. Furthermore, their cross-sectional shape can also represent the representations of Figures 4 and 5 be taken closer. The profile bodies 300 consisting of sheet metal are therefore essentially U-shaped with a bottom surface 301 and two symmetrically designed side walls 302 which together enclose a receiving space open to a light emission side. Here, as in FIG Figure 3 Correspondingly, corresponding bores or openings 305 can be provided, via which the profile body 300 can be attached to or in a ceiling or wall of a room.

The desired flexibility of the profile body 300 is achieved in that, as in particular in the Figures 2 and 3 can be seen, the side walls 302 are slotted. Slots 310 are therefore provided at regular intervals, which extend on the one hand to the free end region of the respective side wall 302, and on the other hand also at least partially into the bottom surface 301. The slots 310 of a side wall 302 are preferably slightly offset compared to the opposite side wall 302, so that the two side walls 302 are subdivided overall into segments arranged offset from one another. As a result, the slots 310, which have a certain thickness, open up the possibility of the profile body 300 being wrapped around the two Figure 2 to bend indicated axes X and Y, which are perpendicular to the axis L defining the longitudinal direction of the profile body 300. The arched or loop-shaped design of the slots 310, which can be seen in the figures, limits the scope for bending to a certain range. At the same time, however, it is ensured that the profile body 300 is still sufficiently stable.

As already mentioned, the principle of this correspondingly slotted profile body 300 is already known from the prior art. Here the further components of the system for forming the light line, in particular the light sources, were then positioned directly in the receiving space formed by the profile body 300. However, it can be seen that in this case it is not possible to achieve a closed receiving space in which the other components of the system are protected from external influences. Moisture or dust can penetrate into the interior of the system, in particular through the slits 310 and at joints between two profile bodies 300 arranged one behind the other and possibly adversely affect the light emission and the functionality of the system.

In the system according to the invention shown in the figures, it is therefore intended to use the profile body 300 primarily as a supporting structure and, if appropriate, as mechanical protection for the other components of the system, but to design the system in such a way that additional measures provide a seal against external influences is achieved. For this purpose, it is provided, independently of the profile bodies 300, to create a channel-like receiving space which is enclosed on all sides and in which the further components of the system, in particular the lighting units, are then arranged.

This receiving space, which is provided with the reference numeral 250, is essentially formed by two profile parts, a so-called tube profile 200 and a cover 100. The shape of both profile parts 100, 200 can in particular be shown in the sectional view of FIG Figure 5 be removed. Accordingly, the tube profile 200 again has a substantially U-shape, which however widens slightly towards the light emission side. Clamping and sealing profiles 210, which are explained in more detail below, are formed on the end regions of the two side walls 202, and two inwardly projecting webs 209 are formed in the region of the bottom surface 201, via which a latching or clamping mounting of the lighting units 40 is realized. In the case shown, the lighting units 40 are LED modules which are positioned one behind the other in the longitudinal direction of the system and are connected to one another, for example, via a cable connection. Depending on how (individually or collectively) control of the light sources 40 is desired and whether they can change the color or color temperature of the emitted light, a more complex or simpler cable connection can be used.

The cover 100 has a plate-like, flat light exit region 105, via which the actual light emission takes place and which is accordingly designed to be translucent. Web-like clamping profiles 110 are then formed on both sides of this plate-like light exit region 105, via which the cover 100 is fastened in a sealing manner.

Both profile parts, ie cover 100 and tube profile 200, are at least partially made of a flexible material, preferably of a soft plastic, such as silicone or the like. In particular, the clamping and sealing profiles 110 and 210 should have the flexibility mentioned in order to achieve the desired seal. However, in order, if necessary, to be able to follow a curved path of the profile parts, this should preferably also apply to the further components, that is to say the bottom wall 201 and the side walls 202 of the tube profile 200 and also to the light emission surface 105 of the cover 100. The design of both profile parts 100, 200 in the form of flexible elements also has the advantage that both profile parts 100, 200 can be deformed or bent in such a way that they are wound up on larger rolls or the like and, accordingly, in any length can be transported to their place of use. Only then are they cut to a length during the assembly of the system, which preferably corresponds to the total length of light line 1, so that both profile parts 100, 200 extend without gaps over the entire length of the system. This principle, which is already used in the WO 2015/165852 A1 a particularly good seal of the receiving space 250 for the lighting units 40 is created in the longitudinal direction of the system.

Before the frontal sealing of the system according to the invention is explained, however, the manner in which the cover 100 and the tubular profile 200 are connected to one another and fastened to the profile bodies 300 serving as the supporting structure will first be described. For this purpose, specially designed web-like support elements, so-called edge profiles 150, are provided, which interact in a special way with the various components of the system. The configuration of these edge profiles 150 can in particular be the sectional view of FIG Figure 6 be removed. For example, these can be extruded aluminum or plastic profiles that are created in the specially shown structure.

It can be seen first of all that the carrier elements 150 have a first insertion region 155 which is open at the bottom and which is delimited laterally on the one hand by a side wall 151 of the carrier element and on the other hand by a web 152 lying opposite this side wall 151. The web 152 is designed in such a way that the insertion area 155 has a lateral extension 156. This insertion area 155 then serves to snap the carrier elements 150 onto the side walls 302 of the profile body 300. These side walls 302 engage with their upper end regions in the insertion region 155, with knobs or protrusions 303 projecting inwards (see Figure 5 ) snap into the extension 156 on the side walls 302. In this way, a latching between profile body 300 and edge profile 150 is achieved.

In addition, the edge profile 150 has two clamping areas open upwards, a first area 160 arranged laterally from the insertion area 155 and a area 165 located above the insertion area 155. Both further clamping areas 160 and 165 additionally have at least one inwardly projecting latching lug 161 and 166, respectively and 167, through which a clamping bracket with the profile parts 100 and 200 is achieved. As namely the representation of Figure 5 can be removed, the lower clamping region 160 is designed to receive a part of the clamping and sealing profile 210 of the hose profile 200 by clamping. The upper clamping area 165 in turn receives the web-like clamping profiles 110 of the cover 100. In addition, the clamping and sealing profile 210 of the tube profile 200 is designed such that in In the assembled state, an upper end region 211 bears against the surface of the light emitting region 105 of the cover 100 facing the receiving space 250, so that a sealing contact between the two elements 100, 200 is achieved here. A mechanical mounting, however, is achieved primarily by the web-like edge profiles 150, which thus serve as central mounting for the components forming the receiving space 250 for the lighting units 40.

When the system is assembled, the edge profiles 150 are then preferably first coupled or clamped to the tube profile 200. The lighting units 40 can then be positioned in the tubular profile, the unit formed in this way then being able to be fastened, for example, to the profile bodies 300. In the final assembly step, the cover 100 is then snapped onto the arrangement, where appropriate the cover could also be attached first to the edge profiles 150 and only subsequently the resulting arrangement is then attached to the profile bodies 300.

It is essential here that the edge profiles 150 hold almost all of the components of the system, and in particular the attachment to other support systems (such as the profile bodies 300) or support structures then takes place via these edge profiles 150. As will be explained in the following, this configuration opens up the possibility of also implementing alternative solutions for mounting the light line system on a wall or ceiling, if necessary.

The measures described so far served to create a receiving space 250 for the lighting units 40 that was sealed over the entire length of the system, so that the light line realized thereby meets, for example, the requirements of a so-called higher degree of protection, for example, against the ingress of dust and / or is protected from moisture. Of course, however, a sealing on the end face of the receiving space 250 is still required, this being done according to the invention by means of specially designed and specially fastened end parts, which will be described in more detail below.

A first special feature of the end parts according to the invention, provided with the reference symbol 50, is the manner in which they are fastened to the components forming the receiving space 250, that is to say the cover 100 and the tubular profile 200. The front parts 50 are at least directly on one of the two profile parts 100, 200 fixed, but preferably on both. Fixing the front parts 50 to the profile parts 100 and 200 has the advantage that the front parts 50 can also carry out any changes in length of the receiving space 250, which can occur due to temperature fluctuations. Despite everything, a complete sealing of the receiving space 250 is achieved.

It is initially provided that the end parts 50 are connected to the hose profile 200 via a screw connection. For example, using Figure 7 or also from Figure 5 It can be seen that the tube profile 200 has a total of four bores or screw channels 220 in the area of the clamping and sealing profiles 210 and on the other hand in the area of the locking projections 209, in which corresponding screws 99 for fastening the end part 50 are to engage. The screw channels 220 are designed as bores which are smaller in diameter than the screws 99. Because of the material of the hose profile 200, the screws 99 then cut into the hose profile 200 with their corresponding threads and thereby reliably lock the front part 50 on the front side End of the tube profile 200. Furthermore, as described in more detail at a later point in time, the end part 50 is additionally glued to the cover 100, but the structure of a end part 50 will first be explained below.

This initially consists of a sheet metal part 60, which represents the central support element of the front part 50 and has a plate-like area 61 which corresponds in terms of its shape to the cross-sectional shape of the tubular profile 200 or the receiving space 250, that is to say is designed to be slightly trapezoidal. On the four side walls of the sheet metal part 60, flaps 62 to 64 facing the receiving space 250 are formed, the side flaps 62 and the bottom flap 63, when fastened, overlap the side walls 202 and the bottom surface 201 of the tubular profile 200 and accordingly stabilize it or support it from the outside . As a result, there is no need for an additional connection between the front part 50 and the tube profile 200 in the region of the walls 201, 202, since despite the flexibility there is no risk that the walls of the tube profile 200 will laterally migrate and the sealing effect will be canceled as a result.

The sealing interaction between the end part 50 and the end faces of the tubular profile 200 is achieved by an additional sealing element 70, which is particularly in the Figures 9 and 10 is recognizable and as a separate component is executed. In comparison to the sheet metal part 60, this sealing element 70 consists of a flexible and therefore better sealing material. First of all, it again has a plate-shaped region 71 corresponding to the cross-sectional shape of the recording mode 250 and an upper angled region 72. The plate-shaped region 71 is in this case designed with a slot 73 at the upper end, which enables the sealing element 70 to be pushed onto the base sheet metal part 60 of the end part by the upper tab 64 of the sheet metal part 60 being passed through the slot 73. This on the one hand enables the sealing element 70 to be fastened to the sheet metal part 60, and on the other hand the upper tab 64 supports the web 72 of the sealing element 70.

On the side of the sheet metal part 60 opposite the sealing element 70, an additional holding element 80 is also arranged, which is connected to the sheet metal part 60 via a rivet connection consisting of three rivets. The holding element 80 has, on the one hand, a lower trough-shaped or pot-shaped receiving area 81, which serves to mount a rubber-like sealing element 65. As can be seen, circular through openings 66, 75, 82 are made both in the holding element 80 and in the sheet metal part 60 and in the sealing element 70, through which the cables can be guided into the receiving area 250. The rubber-like sealing element 65 held by the holding element 80 is intended to provide the appropriate seal in the event that lines are passed through and is accordingly designed for this purpose with suitable sleeves or the like.

A leaf spring 85 is then formed above the area 81 for receiving the sealing element 65, by means of which an additional component, namely a so-called sealing angle 90, is held. This sealing angle rests on the one hand on the back of the sheet metal part 60 and interacts with the leaf spring 85 with an angled projection 91. This therefore fixes the sealing angle 90 on the sheet metal part 60. At the same time, the angle lies flat with an upper web 92 on the web 72 of the sealing element 70. As especially in Figure 8 , which shows the front part 50 in the assembled state, can be seen, then an adhesive strip 95 is provided on the upper side of the web 92 of the sealing bracket 90, which ultimately lies on the inside of the light exit region 105 of the cover 100, that is to say is glued to the cover 100.

After the tube profile 200 has been fastened to the edge profiles 150 as described above and the lamps 40 are positioned in the receiving space 250 the end parts 50 are then screwed to the tubular profile 200 in the manner according to the invention. In the final work step, the cover 100 is then snapped onto the edge profiles 150 from the top side, whereby the clamping and sealing connection is achieved in the longitudinal direction on the one hand, and the cover 100 is simultaneously connected to the adhesive top side of the front part 50 on the end faces. Overall, these measures thus create a completely enclosed receiving space 250, in which the ingress of dirt and / or moisture is prevented. In spite of everything, the measures described ensure that the components forming the receiving space and thus the light line as a whole are designed so flexibly that the resulting light line can optionally also follow a curved path.

As shown above, the edge profiles 150 represent the central holders of the components of the system. The slotted profile bodies 300, on the other hand, are the ones in FIGS Figures 2 to 10 Variant shown with these components connected exclusively via the edge profiles 150 and accordingly represent only an outer bracket for the system. This in turn opens up the possibility of also providing alternative measures for assembly, wherein in the Figures 11 to 14 an alternative solution to this is shown.

Instead of the slotted profile body 300, bow-like holding elements 400 are used, which are positioned at regular intervals along the edge profiles 150. The connection to the edge profiles 150 is carried out in the same way as in the case of the slotted profile bodies 300 described above, that is to say that the bow-like holding elements 400 also have corresponding knockouts or knobs 411 on the upwardly projecting arms 410, via which locking with the edge profiles 150 is done.

The holding elements 400 are designed on their side arms 410 in such a way that they correspond to the double arrow in FIG Figure 12 in comparison to a base web 420, by means of which, for example, screwing to a bare ceiling or the like takes place, are height-adjustable. This in turn means that the distance between the edge profiles 150 and thus the entire light line can be adjusted in comparison to the floor area. Compared to the more inflexible embodiment with the slotted profile bodies 300, this variant therefore offers the possibility of compensating for any inaccuracies in the design of the receiving area, for example the wall or ceiling in which the system is to be installed.

Figure 14 shows the entire system with the bracket-like holding elements 400 arranged thereon, which, as already mentioned, are fastened to the ceiling or wall at appropriate intervals. It can be provided to first mount the holding bracket 400 and then the edge profiles 150 - as in FIG Figure 13 shown - to attach to it. In this situation, the height can be adjusted relatively easily, so that, for example, the upper edges of the edge profiles 150, which can be used, for example, as plastering edges when mounting the system in a wall or ceiling, can be aligned as desired. In the final step, the various components, that is to say the tube profile 200 with the lighting units 40, the front parts 50 are then attached to the edge profiles 150, as described above, and the cover 100 is finally snapped on.

Overall, a system for forming a light line is thus created, which also meets increased requirements with regard to sealing against external influences. At the same time, the construction according to the invention opens up different possibilities for assembling the system, so that it can be used in an extremely versatile and flexible manner.
