Description

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

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

Known light band systems are based on the use of a so-called mounting rail arrangement, which represents the central support for all other components of the lighting system. Such arrangements consist of individual, successively arranged support rail elements, which are e.g. are formed from elongated sheet-metal profile parts, which are open, for example, in cross-section U-shaped and down, so that they form a longitudinally extending receiving space, which is first used once to arrange the components responsible for the power supply of the lighting system of the lighting system. On the one hand, these are the cables for the power supply, which usually run along the entire arrangement, and possibly also for the signal transmission. Furthermore, however, at least the contacting means of lighting modules to be fastened to the mounting rail arrangement are often also accommodated within the receiving space and possibly 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 continuation of the variants described above, the light sources are arranged even within the receiving space in a light line and the underside of the mounting rail assembly 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 practical for such a line of light to realize the cover of individual, longitudinally successively arranged items, as at the joints light more or less unhindered could leave the system and, accordingly, no homogeneous light output can be realized. In an earlier application of the Applicant ( WO 2014/174019 A1 ), therefore, a cover is described, which in principle is made "endless" and is designed such that it can be wound up for transport to a roll. This cover is then arranged in a single piece extending over the entire length of the mounting rail arrangement, so that the optical properties of the system are markedly improved.

Furthermore, from a further application ( WO 2015/165852 A1 ) of the applicant, in addition to line the receiving space of a mounting rail assembly with a longitudinally extending, again preferably integrally formed profile part, which is connectable to the cover. The aim of this measure is to create a receiving space for the electrical and electronic components of the lighting system, which is as well protected from external influences, especially from dust and / or moisture. Since, as mentioned above, the individual mounting rail elements have only a limited length and accordingly usually a mounting rail arrangement consists of several frontally joined mounting rail elements occur at the joints inevitably gaps or openings through which the protection of the components therein is impaired from external influences. This is avoided according to the above-mentioned solution by the applicant in that now the interior is additionally lined with a profile part consisting of a flexible material. Also, this profile part as well as the cover is advantageously designed such that it can be transported wound up into a roll.

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

A first object of the present invention is therefore based in reliably sealing the channel-like receiving space at its frontal areas.

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

In the solution according to the invention, it is again provided in the first place to form the elongate, channel-like receiving space by elongated profile parts, which are each formed at least partially from a flexible material and sealingly connected to form the receiving space. At the two end faces of the receiving space then each end portions are provided, which are fixed to at least one of the profile parts and seal the receiving space on the front side.

It is crucial for the solution according to the invention that the provided for sealing the receiving space end portions cooperate directly sealingly with the receiving space forming profile parts and are also fixed to at least one of the profile parts themselves. Thus, should the receiving space in the longitudinal direction, e.g. due to temperature fluctuations, expand or contract, the corresponding movement is also carried out by the end pieces and the permanent frontal cover of the receiving space is ensured despite everything.

According to the invention, a system for forming a light line with an elongated, channel-like receiving space is provided, which has a light-transmitting light exit area on one side and in which a plurality of lighting units are arranged, wherein at least two elongate profile parts are provided, each formed at least partially of a flexible material are and sealingly connected to form the receiving space, and wherein at the two end faces of the receiving space end portions are provided which are fixed to at least one of the profile parts and the receiving space in each case seal the front side.

The fixing of the end parts preferably takes place in that they are fastened to the at least one profile part by means of a screw connection. For this purpose, it may be provided that the corresponding profile part has channels extending in the longitudinal direction, which are used as screw channels. Particularly preferably, it is provided that the end parts are fixed to a profile part by means of the screw and are glued to the other profile part. In this case, it is particularly appropriate to carry out the adhesive connection with that profile part which forms a translucent cover of the light line.

The end parts themselves are preferably formed in each case by a base part formed from sheet metal, to which then one or more sealing elements made of a flexible material are fastened. In this case, the end parts may each have openings for the passage of cables, which are preferably also sealed. For this purpose, the use of a corresponding rubber sleeve or similar measures offers.

As already mentioned, the two profiled 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 profiled parts and thus the receiving space to 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 above - the profile parts can optionally be wound 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 this in the desired manner. Preferably, however, it is provided that both profile parts are connected to each other via web-like support elements which extend on both sides along the receiving space and on which the receiving space forming profile parts are each clamped. The use of these web-like support elements brings in particular the advantage that they can then be used in a simple manner as a central brackets for the receiving space. At the same time, however, these support elements can also be used as coupling elements for other supporting structures, by means of which the light band is mounted. On the one hand, it can be provided that the support structure is formed in a known manner by a substantially U-shaped channel, which is formed from one or more sheet metal parts. It can be provided in particular that the sheet metal parts forming the channel are slotted in a special way, so that they also allow bending of the channel and thus following curved surfaces. In other situations, however, can even be provided that is dispensed with an outer, the receiving space surrounding additional channel and only bow-like holding elements are used, which form the supporting structure. These are then spaced from each other along the receiving space and coupled via the web-like support elements with the receiving space. Particularly preferably, it is provided that the bow-like holding elements allow a certain height adjustment, which allows, for example, the light exit surface of the light line flush with the surface of a wall to which the assembly is mounted to align.

This flexibility in terms of 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 independently of the manner of the frontal sealing of the receiving space, which is why it is the subject of another independent claim.

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

Based on 1 Let us briefly explain the basic field of application of light lines according to the invention. Shown schematically is the corner region of a generally with the reference numeral 500 provided space, here two adjacent walls 501 as well as the ceiling 502 are recognizable. In the illustrated embodiment, in this corner region on the two side walls 501 two light lines 1 be realized, which should give off light over its length in a uniform brightness. The systems used for this purpose, described in detail below, are in corresponding elongated installation openings of the walls 501 integrated, such that the light emitting surfaces of the two light lines 1 substantially flush with the surrounding surfaces of the walls 501 run. That is, both lines of light 1 in principle complete the surface of the respective wall 501 but just give off light over the corresponding area. Of course, another light line could also be in the area of the ceiling 502 will be realized.

A special feature of the illustrated light lines 1 in 1 consists in the fact that these - as can be seen - follow a curved path. This is not absolutely necessary, however, represents a particularly preferred feature of the system according to the invention, since in this case there is also the possibility of integrating the corresponding systems in surfaces, so walls or ceilings, which have a certain curvature. Compared to a rigidly formed system, this considerably increases the possible use of light lines can be realized in different, visually appealing variants.

Light lines that are suitable to follow a curved path are already known per se and, for example in the EP 2 507 543 B1 the applicant described. In this known embodiment, a substantially U-shaped channel for receiving the light sources is formed by at least partially integral profile body, which are U-shaped and provided with slots that they each bend around two axes that are substantially perpendicular to each other are. In the first embodiment of the system according to the invention for forming a light line, which will be described below with reference to FIGS 2 to 10 be explained, also suitably designed profile body used, which should then form the support structure for the system as a whole.

In the 2 and 3 these are with the reference number 300 provided profiled body recognizable. Furthermore, their cross-sectional shape and the representations of 4 and 5 be taken in more detail. The profile body made of sheet metal 300 are therefore substantially U-shaped with a bottom surface 301 and two symmetrically formed side walls 302 which together enclose a receiving space open towards a light emission side. At the bottom surfaces 301 can hereby like in 3 Recognizable corresponding holes or openings 305 be provided on the attachment of the profile body 300 on or in a ceiling or wall of a room is made possible.

The desired flexibility of the profile body 300 is thereby achieved that, in particular in the 2 and 3 recognizable is the side walls 302 slotted are executed. At regular intervals are slots 310 provided, which on the one hand to the free end of the respective side wall 302 extend, on the other hand, at least partially up to the bottom surface 301 into it. The slots 310 a side wall 302 are preferably compared to the opposite side wall 302 slightly offset so that the two side walls 302 total are divided into staggered segments. As a result, by having a certain thickness slots 310 opened the possibility of the profile body 300 around the two in 2 indicated axes X and Y, perpendicular to the longitudinal direction of the profile body 300 standing axis L to bend. By recognizable in the figures, bulged or loop-shaped design of the slots 310 while the scope for bending is limited to a certain range. At the same time, however, it is ensured that even then sufficient stability of the profile body 300 is present.

The principle of this appropriately slotted running profiled body 300 As already mentioned, it is already known from the prior art. Here then were the other components of the system for forming the light line, in particular the light sources directly in the through the profile body 300 positioned receiving space positioned. However, it can be seen that in this case no closed receiving space can be achieved in which the other components of the system are protected from external influences. Especially through the slots 310 and at joints between two successively arranged profile bodies 300 Moisture or dust may enter the interior of the system and, if necessary, adversely affect the light output and functionality of the system.

In the system according to the invention shown in the figures is therefore provided, the profile body 300 to use primarily as a support structure and possibly as a mechanical protection for the other components of the system, however, to design the system so that a seal against external influences is achieved by additional measures. For this purpose, it is provided, regardless of the profile bodies 300 to provide a channel-shaped receiving space enclosed on all sides, in which then the other components of the system, in particular the lighting units are arranged.

This with the reference number 250 provided receiving space is essentially formed by two profile parts, a so-called hose profile 200 as well as a cover 100 , The shape of both profile parts 100 . 200 can in particular the sectional view of 5 be removed. Accordingly, the hose profile 200 again essentially a U-shape, which, however, widens slightly towards the light emission side. At the end areas of the two side walls 202 are described in more detail below clamping and sealing profiles 210 trained, in the area of the floor area 201 are two inwardly projecting webs 209 designed, via which a latching or clamping holder of the lighting units 40 is realized. In the case shown, it is the lighting units 40 around LED modules, which are distributed in the longitudinal direction of the system distributed one behind the other and are connected to each other, for example via a cable connection. Depending on how (individually or collectively) an activation of the light sources 40 is desired and if they can possibly change the color or color temperature of the emitted light can In this case, a more complex or simpler cable connection are used.

The cover 100 has a plate-like, flat light exit area 105 on, over which the actual light emission takes place and which is accordingly made translucent. On both sides of this plate-like light exit area 105 are then web-like clamping profiles 110 formed over the a sealing attachment of the cover 100 he follows.

Both profile parts, so cover 100 and hose profile 200 consist at least partially 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 mentioned flexibility to achieve the desired seal. However, if necessary, to be able to follow a curved path of the profile parts, this should preferably also for the other components, ie the bottom wall 201 as well as the side walls 202 the hose profile 200 as well as for the light emission surface 105 the cover 100 be valid. The design of both profile parts 100 . 200 in the form of flexible elements also brings with it the advantage that both profile parts 100 . 200 can be deformed or bent so that they can be wound onto larger rollers or the like before their assembly and accordingly transported in any length to their place of use. Only then do they become part of the assembly of the system to a length, preferably the total length of the light line 1 Corresponds to, cut off so that both profile parts 100 . 200 extend completely over the entire length of the system. By this principle, which, for example, already in the WO 2015/165852 A1 Applicant is described, in the longitudinal direction of the system, a particularly good sealing of the receiving space 250 for the lighting units 40 created.

Before the end-face sealing of the system according to the invention is explained, however, it will first be described in what way cover 100 and hose profile 200 connected to each other and on the profile body serving as a support structure 300 be attached. For this purpose, specially designed web-like support elements, so-called. Edge profiles 150 provided that interact in a special way with the various components of the system. The design of these edge profiles 150 can in particular the sectional view of 6 be removed. For example, these may be extruded aluminum or plastic profiles, which are produced in the structure shown specifically.

It is initially apparent that the support elements 150 a first lead-in area open at the bottom in the illustration 155 have, laterally on the one hand by a side wall 151 the support member and on the other hand of one of these side wall 151 opposite jetty 152 is limited. The jetty 152 is here designed such that the introduction area 155 a lateral extension 156 having. This introductory area 155 then serves to the carrier elements 150 on the side walls 302 the profile body 300 snap up. These sidewalls 302 grip with their upper end into the lead-in area 155 a, wherein inwardly projecting nubs or characteristics 303 (please refer 5 ) on the side walls 302 in the extension 156 snap. This will be a catch between profile body 300 and edge profile 150 achieved.

In addition, the edge profile has 150 two upwardly open clamping areas, one laterally from the lead-in area 155 arranged first area 160 and one above the lead-in area 155 lying area 165 , Both additional clamping areas 160 and 165 additionally have at least one inwardly projecting latch 161 respectively 166 and 167 on, through which a clamping bracket with the profile parts 100 respectively. 200 is achieved. Namely, in particular, the representation of 5 can be removed, here is the lower clamping area 160 designed to clamp a part of the clamping and sealing profile 210 the hose profile 200 take. The upper clamping area 165 again takes the web-like clamping profiles 110 the cover 100 on. In addition, the clamping and sealing profile 210 the hose profile 200 executed such that in the assembled state, an upper end portion 211 at the reception room 250 facing surface of the Lichtabstrahlbereichs 105 the cover 100 is applied, so here is a sealing concern between the two elements 100 . 200 is achieved. A mechanical support is, however, primarily by the web-like edge profiles 150 achieved, which thus serves as central mounts for the recording room 250 for the lighting units 40 serve forming components.

In an assembly of the system are then preferably first the edge profiles 150 with the hose profile 200 coupled or jammed. Subsequently, the lighting units 40 be positioned in the tube profile, wherein the unit thus formed then, for example, to the profile bodies 300 can be attached. In the final assembly step then the cover 100 snapped onto the arrangement, optionally also first attaching the cover to the edge profiles 150 could be done and only then from this resulting arrangement then on the profile bodies 300 is attached.

Essential here is that so the edge profiles 150 hold almost all components of the system and especially about these edge profiles 150 then the attachment to other support systems (as here the profile bodies 300 ) or supporting structures takes place. As will be explained below, this embodiment opens up the possibility, if appropriate, of realizing alternative solutions for mounting the light line system on a wall or ceiling.

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

A first particularity of the invention, with the reference numeral 50 provided end parts consists in which way this to the receiving space 250 forming components, ie the cover 100 and the hose profile 200 are fastened. So are the forehead parts 50 directly on at least one of the two profile parts 100 . 200 fixed, but preferably at both. Fixing the forehead parts 50 at the profile parts 100 respectively 200 brings with it the advantage that the forehead parts 50 any changes in length of the receiving space 250 , which can occur due to temperature fluctuations, can perform with. Despite everything, a complete seal of the recording room 250 achieved.

It is initially provided that the end parts 50 with the hose profile 200 be connected via a screw connection. For example, based on 7 or also from 5 can be seen has the hose profile 200 on the one hand in the area of clamping and sealing profiles 210 and on the other hand in the area of the locking projections 209 a total of four holes or screw channels 220 on, in which respective screws 99 for fixing the front part 50 should intervene. The screw channels 220 are designed as holes that are smaller in diameter than the screws 99 , Due to the material of the hose profile 200 cut the screws 99 then with their corresponding threads in the hose profile 200 and thereby reliably lock the front part 50 at the front end of the hose profile 200 , Further takes place - as described at a later time in more detail - additionally gluing the front part 50 with the cover 100 but below, first, the structure of a front part 50 should be explained.

This consists initially of a sheet metal part 60 which is the central support element of the front part 50 represents and a plate-like area 61 having, in terms of its shape, the cross-sectional shape of the tubular profile 200 or the recording room 250 corresponds, so it is slightly trapezoidal. On the four side walls of the sheet metal part 60 are each the recording room 250 facing flaps 62 to 64 formed, with the side flaps 62 as well as the bottom flap 63 in the attached state, the side walls 202 or the floor area 201 the hose profile 200 overlap and stabilize accordingly or support from the outside. This eliminates the need for an additional connection between the front part 50 and hose profile 200 in the area of the walls 201 . 202 , because despite the flexibility there is no risk that the walls of the hose profile 200 emigrate accordingly laterally and thereby the sealing effect is lifted.

The sealing interaction between the front part 50 and the frontal surfaces of the hose profile 200 is doing by an additional sealing element 70 achieved in particular in the 9 and 10 recognizable and is designed as a separate component. Compared to the sheet metal part 60 there is this sealing element 70 from a flexible and thus better sealing material. It first again has one of the cross-sectional shape of the recording mode 250 corresponding plate-shaped area 71 and an upper angled area 72 on. The plate-shaped area 71 is here at the top with a slot 73 executed, which allows the sealing element 70 on the base sheet metal part 60 of the front part is pushed by the upper flap 64 of the sheet metal part 60 through the slot 73 is passed. As a result, on the one hand the attachment of the sealing element 70 on the sheet metal part 60 on the other hand supports the upper flap 64 the jetty 72 of the sealing element 70 from.

At the the sealing element 70 opposite side of the sheet metal part 60 is still an additional support element 80 arranged, which has a riveted joint consisting of three rivets with the sheet metal part 60 connected is. The support element 80 has on the one hand a lower trough or cup-shaped receiving area 81 on, the storage of a rubber-like sealing element 65 serves. As can be seen, are both in the support member 80 as well as in the sheet metal part 60 and the sealing element 70 circular passage openings 66 . 75 . 82 executed by the passage of cables in the receiving area 250 is possible. That of the support element 80 held rubbery sealing element 65 should in this case in the event that lines are passed, provide the appropriate seal and is accordingly designed for this purpose with suitable sleeves or the like.

Above the range 81 for receiving the sealing element 65 is then a leaf spring 85 formed over which the holder of an additional component, namely a so-called sealing angle 90 he follows. This sealing angle is on the one hand on the back of the sheet metal part 60 and acts with an angled projection 91 with the leaf spring 85 together. This fixes the sealing angle 90 on the sheet metal part 60 , At the same time the angle is with an upper web 92 flat on the jetty 72 of the sealing element 70 on. As in particular in 8th that the front part 50 in the assembled state shows, recognizable, is then at the top of the web 92 the sealing angle 90 an adhesive tape 95 provided, which ultimately at the inside of the light exit area 105 the cover 100 is applied, so with the cover 100 is glued.

So as described above, the hose profile 200 at the edge profiles 150 was attached and the bulbs 40 in the recording room 250 are positioned, then the end parts 50 in the manner according to the invention with the hose profile 200 screwed. In the final step then the cover 100 from the top to the edge profiles 150 snapped on, on the one hand, in the longitudinal direction, the clamping and sealing connection is achieved, at the same time on the front sides of the cover 100 with the adhesive top of the front part 50 is connected. Overall, these measures therefore a completely enclosed recording room 250 created, in which the ingress of dirt and / or moisture is prevented. Nevertheless, it is ensured on the basis of the measures described that the components forming the receiving space and thus the light line as a whole are so flexible that, if appropriate, the resulting light line can also follow a curved path.

As pictured above, make the edge profiles 150 Central brackets of system components. Slotted profiled bodies 300 however, are in the in the 2 to 10 illustrated variant with these components exclusively on the edge profiles 150 Accordingly, only one external support for the system is connected, and this in turn opens up the possibility of also providing alternative measures for the installation, wherein in the 11 to 14 an alternative solution to this is shown.

Instead of the slotted profile body 300 come here bow-like holding elements 400 used, at regular intervals along the edge profiles 150 be positioned. The connection with the edge profiles 150 takes place in the same way as in the above-described slotted profile bodies 300 , that is, also the bow-like holding elements 400 indicate upturned arms 410 respectively corresponding knockouts or nubs 411 on, about which a latching with the edge profiles 150 he follows.

The holding elements 400 are at their side arms 410 executed such that these according to the double arrow in 12 compared to a base bar 420 , on the example, a screwing with a raw ceiling or the like, are made adjustable in height. This in turn means that the distance of the edge profiles 150 and thus the entire light line compared to the floor surface can be adjusted. Compared to the inflexible embodiment with the slotted profile bodies 300 In this variant, therefore, it is possible to compensate for any inaccuracies in the design of the receiving area, for example the wall or ceiling in which the system is to be mounted.

14 shows here the entire system with the bracket-like holding elements arranged thereon 400 which, as already mentioned, are fastened at appropriate intervals to the ceiling or wall. It can be provided, first the headband 400 to assemble and then the edge profiles 150 - as in 13 shown - attached to it. In this situation, a height adjustment can be relatively easily made, so that, for example, the upper edges of the edge profiles 150 , which can be used, for example, as plaster edges when mounting the system in a wall or ceiling, can be aligned in the desired manner. In the final step then as described above, the various components, ie the hose profile 200 with the lighting units 40 , the forehead parts 50 at the edge profiles 150 attached and finally the cover 100 snapped.

Overall, therefore, a system for forming a light line is created, which also meets increased requirements in terms of sealing against external influences. At the same time, the structure of the invention opens up different possibilities for mounting the system, so that this is extremely versatile and flexible.
