Definitions
- 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.
- these are the cables for the power supply, which usually run along the entire arrangement, and possibly also for the signal transmission.
- 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.
- 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.
- the light exit element should appear uniformly bright and of the same color over the entire length of the system.
- 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.
- 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.
- the interior is additionally lined with a profile part consisting of a flexible material.
- this profile part as well as the cover is advantageously designed such that it can be transported wound up into a roll.
- a first object of the present invention is therefore to reliably seal the channel-like receiving space at its end regions.
- 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.
- 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.
- a system for forming a light line with an elongated, channel-like receiving space 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 are connected to form the receiving space sealingly, 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.
- the corresponding profile part has channels extending in the longitudinal direction, which are used as screw channels.
- 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.
- the end parts may each have openings for the passage of cables, which are preferably also sealed.
- the use of a corresponding rubber sleeve or similar measures offers.
- 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.
- 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.
- these support elements can also be used as coupling elements for other supporting structures, by means of which the light band is mounted.
- 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.
- the Channel-forming sheet metal parts are slotted in a special way, so that they also allow bending of the channel and thus following curved surfaces.
- 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.
- 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.
- a system for forming a light line with an elongated, channel-like receiving space 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.
- FIG. 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 provided with the reference numeral 500 space, here two adjoining walls 501 and the ceiling 502 can be seen.
- two light lines 1 are to be realized in this corner region on the two side walls 501, which in a long time over its length uniform brightness to give off light.
- the systems used for this purpose described in detail below, are integrated into corresponding elongated installation openings of the walls 501 such that the light emission surfaces of the two light lines 1 are substantially flush with the surrounding surfaces of the walls 501. 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.
- another light line could also be realized in the area of the ceiling 502.
- a special feature of the illustrated light lines 1 in FIG. 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. In comparison to a rigidly formed system, this considerably increases the possibility of use and light lines can be realized in a wide variety of visually appealing variants.
- 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.
- profile body used, which should then form the support structure for the system as a whole.
- FIGS. 2 and 3 These are provided with the reference numeral 300 profile body recognizable. Furthermore, their cross-sectional shape and the representations of FIGS. 4 and 5 be taken in more detail.
- the profiled bodies 300 consisting of sheet metal are thus 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.
- Recognizable corresponding holes or openings 305 may be provided, via which an attachment of the profile body 300 is made possible on or in a ceiling or wall of a room.
- the desired flexibility of the profile body 300 is achieved in that, in particular as in the FIGS. 2 and 3 can be seen, the side walls 302 are designed slotted. At regular intervals, therefore, slots 310 are provided, which extend on the one hand to the free end region of the respective side wall 302, on the other hand, at least partially into the bottom surface 301 inside.
- the slots 310 of a side wall 302 are preferably slightly offset relative to the opposite side wall 302, so that the two side walls 302 are divided into segments that are offset from one another.
- slots 310 opens the possibility of the profile body 300 to the two in FIG.
- axes X and Y which are perpendicular to the longitudinal axis of the profile body 300 defining axis L to bend.
- this profile body 300 which has been slit accordingly, is already known from the prior art.
- the other 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 bodies 300.
- no closed receiving space can be achieved in which the other components of the system are protected from external influences.
- moisture or dust can penetrate into the interior of the system and possibly adversely affect the light output and the functionality of the system.
- the profile body 300 primarily as a support structure and possibly as mechanical protection for the other components of the system, however, to design the system such that by additional measures a seal against external influences is achieved.
- it is provided independently of the profile bodies 300 to create a channel-like receiving space enclosed on all sides, in which then the other components of the system, in particular the lighting units, are arranged.
- This provided with the reference numeral 250 receiving space is thereby formed essentially by two profile parts, a so-called hose profile 200 and a cover 100.
- the shape of both profile parts 100, 200, in particular the sectional view of FIG. 5 be removed.
- 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, in the area of the bottom surface 201 two inwardly projecting webs 209 are formed, via which a latching or clamping support of the lighting units 40 is realized.
- the illumination units 40 are LED modules which are positioned one after the other in the longitudinal direction of the system and, for example, connected to one another via a cable connection.
- a more complex or simpler cable connection can be used in this case.
- the cover 100 has a plate-like, planar light exit region 105, via which the actual light emission takes place and which is accordingly designed to be light-permeable. On both sides of this plate-like light exit region 105, web-like clamping profiles 110 are then formed, via which a sealing attachment of the cover 100 takes place.
- Both profile parts, ie cover 100 and tube profile 200 consist at least partially of a flexible material, preferably of a soft plastic, such as silicone or the like.
- the clamping and sealing profiles 110 and 210 should have the mentioned flexibility to achieve the desired seal.
- this should preferably also apply to the other components, that is to say the bottom wall 201 and the side walls 202 of the tubular profile 200 as well as the light emission surface 105 of the cover 100.
- the design of the two 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 wound before mounting on larger rollers or the like and accordingly in any length can be transported to their place of use.
- Edge profiles 150 are provided which interact in a special way with the various components of the system.
- the design of these edge profiles 150 may in particular the sectional view of FIG. 6 be removed.
- these may be extruded aluminum or plastic profiles, which are produced in the structure shown specifically.
- the carrier elements 150 have a first insertion region 155, which is open at the bottom in the illustration, which is delimited laterally on one side by a side wall 151 of the carrier element and on the other side by a web 152 opposite this side wall 151.
- the web 152 is in this case designed such that the introduction region 155 has a lateral extension 156.
- This introduction region 155 then serves to snap the carrier elements 150 onto the side walls 302 of the profile bodies 300. These side walls 302 engage with their upper end portions in the insertion area 155, wherein inwardly projecting nubs or shapes 303 (see FIG. 5 ) on the side walls 302 snap into the extension 156. As a result, a locking between profile body 300 and edge profile 150 is achieved.
- the edge profile 150 has two clamping regions which are open at the top, a first region 160 arranged laterally from the introduction region 155 and a region 165 located above the introduction region 155. Both further clamping regions 160 and 165 additionally have at least one inwardly projecting latching lug 161 or 166 and 167, by which a clamping bracket with the profile parts 100 and 200 is achieved. Namely, in particular, the representation of FIG. 5 can be removed, in this case the lower clamping portion 160 is designed to clampingly receive a part of the clamping and sealing profile 210 of the tube profile 200. The upper clamping region 165 in turn receives the web-like clamping profiles 110 of the cover 100.
- clamping and sealing profile 210 of the tube profile 200 is designed such that in assembled state, an upper end portion 211 on the receiving space 250 facing surface of the Lichtabstrahl Schemes 105 of the cover 100 is applied, so that here a sealing contact between the two elements 100, 200 is achieved.
- a mechanical support is achieved primarily by the web-like edge profiles 150, which thus serve as central supports for the receiving space 250 for the lighting units 40 forming components.
- the edge profiles 150 are then preferably first coupled or clamped to the hose profile 200. Subsequently, the lighting units 40 can be positioned in the hose profile, wherein the unit thus formed can then be attached to the profile bodies 300, for example. In the final assembly step, the cover 100 is then snapped onto the arrangement, it being possible for the cover to be attached to the edge profiles 150 first, if necessary, and only then the arrangement resulting therefrom to be attached to the profile bodies 300.
- edge profiles 150 hold almost all components of the system and in particular via these edge profiles 150 then the attachment to other support systems (such as the profile bodies 300) or support structures takes place.
- this embodiment opens up the possibility, if appropriate, of realizing alternative solutions for mounting the light line system on a wall or ceiling.
- a first special feature of the invention provided with the reference numeral 50 end parts consists therein, in which way they are fastened to the receiving space 250 forming components, so the cover 100 and the hose profile 200.
- the end parts 50 are directly on at least one of the two profile parts 100, 200 fixed, but preferably at both.
- the fixing of the end portions 50 to the profile parts 100 and 200 brings with it the advantage that the end portions 50 can perform any changes in length of the receiving space 250, which may occur due to temperature fluctuations with. Despite all, a complete seal of the receiving space 250 is achieved.
- the end portions 50 are connected to the hose profile 200 via a screw connection.
- the hose profile 200 on the one hand in the region of the clamping and sealing profiles 210 and on the other hand in the region of the locking projections 209 a total of four holes or screw channels 220, in each of which corresponding screws 99 are intended to engage the attachment of the front part 50.
- the screw channels 220 are designed as holes that are dimensioned smaller than the screws 99 in terms of their diameter.
- This consists initially of a sheet metal part 60, which is the central support member of the end portion 50 and has a plate-like portion 61 which corresponds in shape to the cross-sectional shape of the tube profile 200 and the receiving space 250, so it is slightly trapezoidal.
- each of the receiving space 250 facing tabs 62 to 64 are formed, the side flaps 62 and the bottom flap 63 in the attached state, the side walls 202 and the bottom surface 201 of the tube profile 200 overlap and stabilize this accordingly or supported from the outside , This results in no need for an additional connection between the front part 50 and hose profile 200 in the region of the walls 201, 202, since despite the flexibility is not the risk that the walls of the hose profile 200 accordingly emigrate sideways and thus the sealing effect is repealed.
- this sealing element 70 consists of a flexible and thus better sealing material.
- the plate-shaped region 71 is in this case designed at the upper end with a slot 73, which makes it possible that the sealing element 70 is pushed onto the base sheet metal part 60 of the front part by the upper tab 64 of the sheet metal part 60 is passed through the slot 73.
- the upper flap 64 supports the web 72 of the sealing element 70 from.
- an additional support member 80 is further arranged, which is connected via a rivet connection consisting of three rivets to the sheet metal part 60.
- the support member 80 has on the one hand a lower trough-shaped or pot-shaped receiving region 81, which serves to support a rubber-like sealing element 65.
- a rubber-like sealing element 65 As can be seen, in both the support member 80 and in the sheet metal part 60 and the sealing member 70 circular bushing openings 66, 75, 82 executed, by the passage of cables in the receiving area 250 is made possible.
- the held by the support member 80 rubber-like sealing element 65 is here in the event that lines are passed, provide the appropriate seal and is accordingly designed for this purpose with suitable sleeves or the like.
- a leaf spring 85 is then formed, via which the holder of an additional component, namely a so-called sealing angle 90 takes place.
- This sealing angle is applied on the one hand to the back of the sheet metal part 60 and cooperates with an angled projection 91 with the leaf spring 85. This fixes the sealing angle 90 on the sheet metal part 60.
- the angle with an upper web 92 lies flat on the web 72 of the sealing element 70.
- an adhesive strip 95 is provided at the top of the web 92 of the sealing angle 90, which ultimately rests against the inside of the light exit region 105 of the cover 100, that is glued to the cover 100.
- the tube profile 200 has been attached to the edge profiles 150 and the bulbs 40 are positioned in the receiving space 250 were then the end portions 50 are screwed in the manner according to the invention with the hose profile 200.
- the cover 100 is then snapped on the edge profiles 150 from the top, on the one hand this longitudinally the clamping and sealing connection is achieved, at the same time at the end faces the cover 100 is connected to the adhesive top of the front part 50.
- a completely enclosed receiving space 250 is created by these measures, in the penetration 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.
- edge profiles 150 represent the central supports of the components of the system.
- the slotted profile bodies 300 are in the case of the FIGS. 2 to 10 variant shown connected to these components exclusively on the edge profiles 150 and accordingly represent only an external support for the system. This in turn opens up the possibility to provide alternative measures for mounting, wherein in the FIGS. 11 to 14 an alternative solution to this is shown.
- bow-shaped retaining elements 400 are used, which are positioned at regular intervals along the edge profiles 150.
- the connection with the edge profiles 150 is carried out in the same manner as in the above-described slotted profile bodies 300, that is, the bow-like holding elements 400 have upwardly projecting arms 410 respectively corresponding knockouts or nubs 411, via which a latching with the edge profiles 150 takes place.
- the holding elements 400 are designed on their side arms 410 such that they correspond to the double arrow in FIG. 12 in comparison to a base web 420, via which, for example, screwing with a raw ceiling or the like, are designed to be height adjustable. 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 less flexible embodiment with the slotted profiled bodies 300, in this variant it is therefore 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.
- FIG. 14 in this case shows the entire system with the bow-like holding elements 400 disposed thereon, which are fixed as already mentioned at appropriate intervals on the ceiling or wall. It may be provided to first mount the headband 400 and then the edge profiles 150 - as in FIG. 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.
- the various components ie the hose profile 200 with the lighting units 40, the end parts 50 are fastened to the edge profiles 150 and finally the cover 100 is snapped on.

Description
Die vorliegende Erfindung betrifft ein System zum Bilden einer so genannten Lichtlinie, bei dem ein länglicher, kanalartiger Aufnahmeraum gebildet wird, der an einer Seite einen lichtdurchlässigen Lichtaustrittsbereich aufweist und in dem mehrere Beleuchtungseinheiten angeordnet sind.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.
Lichtlinien, welche Gegenstand der vorliegenden Erfindung sind, stellen Spezialfälle so genannter Lichtbandsysteme dar. Derartige Lichtbandsysteme finden in der Beleuchtungstechnologie vielfach Verwendung, da sie eine flexible Anpassung der Beleuchtung an äußere Gegebenheiten ermöglichen.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.
Bekannte Lichtbandsysteme beruhen auf der Verwendung einer so genannten Tragschienenanordnung, welche die zentrale Halterung für alle weiteren Komponenten des Lichtbandsystems darstellt. Derartige Anordnungen bestehen aus einzelnen, hintereinander angeordneten Tragschienenelementen, die z.B. aus länglichen Blechprofilteilen gebildet sind, welche beispielsweise im Querschnitt U-förmig und nach unten geöffnet sind, so dass sie einen sich in Längsrichtung erstreckenden Aufnahmeraum bilden, der zunächst einmal zur Anordnung der für die Stromversorgung der Leuchtmittel des Lichtbandsystems verantwortlichen Komponenten genutzt wird. Es handelt sich hierbei einerseits um die üblicherweise entlang der gesamten Anordnung verlaufenden Kabel für die Stromversorgung sowie gegebenenfalls auch für die Signalübertragung. Des Weiteren werden oftmals allerdings auch zumindest die Kontaktierungsmittel von an der Tragschienenanordnung zu befestigenden Leuchtmodulen innerhalb des Aufnahmeraums aufgenommen sowie gegebenenfalls auch zugehörige Betriebsgeräte wie Konverter oder dergleichen, mit deren Hilfe die durch die Durchgangsverdrahtung zur Verfügung gestellte Stromversorgung in einen zum Betrieb der Lichtquellen geeigneten Strom umgesetzt wird.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 Weiterführung der oben beschriebenen Varianten sind bei einer Lichtlinie die Lichtquellen selbst innerhalb des Aufnahmeraums angeordnet und die Unterseite der Tragschienenanordnung wird dann durch eine lichtdurchlässige Abdeckung verschlossen, welche das Lichtaustrittselement der auf diese Weise realisierten Lichtlinie bildet. In der Regle soll dabei über die gesamte Länge des Systems hinweg das Lichtaustrittselement gleichmäßig hell und mit gleicher Farbe erscheinen.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.
Aus optischen Gründen ist es bei einer derartigen Lichtlinie wenig praktikabel, die Abdeckung aus einzelnen, in Längsrichtung hintereinander angeordneten Einzelteilen zu realisieren, da an den Stoßstellen Licht mehr oder weniger ungehindert das System verlassen könnte und dementsprechend keine homogene Lichtabgabe mehr realisiert werden kann. In einer früheren Anmeldung der Anmelderin (
Ferner ist aus einer weiteren Anmeldung (
Mit Hilfe der oben beschriebenen Lösung kann also ein über seine gesamte Länge hinweg dicht umschlossener Aufnahmeraum geschaffen werden, in dem dann die Anordnung der weiteren Komponenten der Lichtlinie erfolgt, wobei ein besonderer Vorteil der aus den genannten Anmeldungen bekannten Lösungen darin besteht, dass die exakte Länge des Aufnahmeraums und damit bspw. der Lichtlinie durch den Endverbraucher frei eingestellt werden kann. Er muss lediglich vor Ort die Tragschienen sowie die zum Bilden des Aufnahmeraums vorgesehenen Profilteile in der gewünschten Länge abschneiden. Dies bedeutet jedoch wiederum, dass werksseitig keine stirnseitigen Abdichtungen des Aufnahmeraums vorgenommen werden können, sondern auch dies vor Ort bei der Endmontage des Systems erfolgen muss.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 adjusted 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 factory no frontal seals of the receiving space can be made, but this must be done on-site during the final assembly of the system.
Eine erste der vorliegenden Erfindung zugrunde liegende Aufgabenstellung besteht deshalb darin, den kanalartigen Aufnahmeraum an seinen Stirnbereichen zuverlässig abzudichten.A first object of the present invention is therefore to reliably seal the channel-like receiving space at its end regions.
Die Aufgabe wird durch ein System zum Bilden einer Lichtlinie, welches die Merkmale des Anspruchs 1 aufweist, gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.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.
Bei der erfindungsgemäßen Lösung ist zunächst wiederum vorgesehen, den länglichen, kanalartigen Aufnahmeraum durch längliche Profilteile zu bilden, welche jeweils zumindest teilweise aus einem flexiblen Material gebildet sind und zum Bilden des Aufnahmeraums dichtend miteinander verbunden sind. An den beiden Stirnseiten des Aufnahmeraums sind dann jeweils Stirnteile vorgesehen, welche an zumindest einem der Profilteile fixiert sind und den Aufnahmeraum stirnseitig abdichten.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.
Entscheidend ist für die erfindungsgemäße Lösung, dass die zum Abdichten des Aufnahmeraums vorgesehenen Stirnteile unmittelbar dichtend mit den den Aufnahmeraum bildenden Profilteilen zusammenwirken und darüber hinaus an zumindest einem der Profilteile selbst fixiert sind. Sollte sich also der Aufnahmeraum in Längsrichtung, z.B. aufgrund von Temperaturschwankungen, ausdehnen oder zusammenziehen, wird die entsprechende Bewegung auch durch die Stirnteile durchgeführt und die dauerhafte stirnseitige Abdeckung des Aufnahmeraums ist trotz allem sichergestellt.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.
Erfindungsgemäß ist dementsprechend ein System zum Bilden einer Lichtlinie mit einem länglichen, kanalartigen Aufnahmeraum vorgesehen, der an einer Seite einen lichtdurchlässigen Lichtaustrittsbereich aufweist und in dem mehrere Beleuchtungseinheiten angeordnet sind, wobei zumindest zwei längliche Profilteile vorgesehen sind, welche jeweils zumindest teilweise aus einem flexiblen Material gebildet sind und zum Bilden des Aufnahmeraums dichtend miteinander verbunden sind, und wobei an den beiden Stirnseiten des Aufnahmeraums Stirnteile vorgesehen sind, welche an zumindest einem der Profilteile fixiert sind und den Aufnahmeraum jeweils stirnseitig abdichten.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 are connected to form the receiving space sealingly, 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.
Vorzugsweise erfolgt das Fixieren der Stirnteile dadurch, dass diese mittels einer Schraubverbindung an dem zumindest einem Profilteil befestigt sind. Hierfür kann vorgesehen sein, dass das entsprechende Profilteil sich in Längsrichtung erstreckende Kanäle aufweist, die als Schraubkanäle genutzt werden. Besonders bevorzugt ist hierbei vorgesehen, dass die Stirnteile an einem Profilteil mittels der Schraubverbindung fixiert sind und mit dem anderen Profilteil verklebt sind. Hierbei bietet sich insbesondere an, die klebende Verbindung mit demjenigen Profilteil durchzuführen, welches eine lichtdurchlässige Abdeckung der Lichtlinie bildet.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.
Die Stirnteile selbst sind vorzugsweise jeweils durch ein aus Blech gebildetes Basisteil gebildet, an dem dann ein oder mehrere aus einem flexiblen Material bestehende Dichtelemente befestigt sind. Dabei können die Stirnteile jeweils Öffnungen zum Durchführen von Kabeln aufweisen, welche vorzugsweise ebenfalls abgedichtet sind. Hierfür bietet sich der Einsatz einer entsprechenden Gummimanschette oder vergleichbarer Maßnahmen an.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.
Die beiden Profilteile zum Bilden des Aufnahmeraums bestehen wie bereits erwähnt vorzugsweise aus einem flexiblen Material, beispielsweise aus Silikon oder dergleichen, welches es ferner auch ermöglicht, dass die Profilteile und damit der Aufnahmeraum in Längsrichtung der Lichtlinie eine Krümmung aufweisen können. Das Lichtband soll also in der Lage sein, gekrümmten Oberflächen zu folgen. Ein weiterer Vorteil der Verwendung des flexiblen Materials für die Profilteile besteht darin, dass - wie eingangs beschrieben - die Profilteile gegebenenfalls aufgewickelt und in dieser Form einfach transportiert werden können.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.
Beide Profilteile können dabei formschlüssig oder klemmend miteinander verbunden sein, um in Längsrichtung des Aufnahmeraums diesen in der gewünschten Weise abzudichten. Vorzugsweise ist jedoch vorgesehen, dass beide Profilteile über stegartige Trägerelemente miteinander verbunden sind, welche sich zu beiden Seiten entlang des Aufnahmeraums erstrecken und an denen die den Aufnahmeraum bildenden Profilteile jeweils klemmend befestigt sind. Die Verwendung dieser stegartigen Trägerelemente bringt dabei insbesondere den Vorteil mit sich, dass diese dann in einfacher Weise als zentrale Halterungen für den Aufnahmeraum genutzt werden können. Gleichzeitig können diese Trägerelemente jedoch auch als Kupplungselemente für weitere Tragkonstruktionen genutzt werden, mit deren Hilfe das Lichtband montiert wird. Einerseits kann vorgesehen sein, dass die Tragkonstruktion in bekannter Weise durch einen im Wesentlichen U-förmigen Kanal gebildet ist, der aus einem oder mehreren Blechteilen gebildet wird. Hierbei kann insbesondere vorgesehen sein, dass die den Kanal bildenden Blechteile in besonderer Weise geschlitzt sind, so dass sie ebenfalls ein Biegen des Kanals und damit ein Folgen gekrümmter Oberflächen ermöglichen. In anderen Situationen hingegen kann sogar vorgesehen sein, dass auf einen äußeren, den Aufnahmeraum umgebenden zusätzlichen Kanal verzichtet wird und lediglich bügelartige Halteelemente zum Einsatz kommen, welche die Tragkonstruktion bilden. Diese sind dann beabstandet zueinander entlang des Aufnahmeraums angeordnet und über die stegartigen Trägerelemente mit dem Aufnahmeraum gekoppelt. Besonders bevorzugt ist hierbei vorgesehen, dass die bügelartigen Halteelemente eine gewisse Höhenverstellbarkeit ermöglichen, die es gestattet, beispielsweise die Lichtaustrittsfläche der Lichtlinie bündig zur Oberfläche einer Wand, an der die Anordnung montiert wird, auszurichten.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. This can be provided in particular that the the Channel-forming sheet metal parts 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.
Diese Flexibilität hinsichtlich der Montage wird insbesondere durch den Einsatz der oben erwähnten stegartigen Trägerelemente, welche den eigentlichen kanalartigen Aufnahmeraum halten, ermöglicht. Dieser Gedanke kann dabei unabhängig von der Art und Weise der stirnseitigen Abdichtung des Aufnahmeraums realisiert werden, weshalb er Gegenstand eines weiteren unabhängigen Anspruchs ist.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.
Gemäß diesem zweiten Aspekt der Erfindung wird also ein System zum Bilden einer Lichtlinie mit einem länglichen, kanalartigen Aufnahmeraum vorgeschlagen, der an einer Seite einen lichtdurchlässigen Lichtaustrittsbereich aufweist und in dem mehrere Beleuchtungseinheiten angeordnet sind, wobei zumindest zwei längliche Profilteile vorgesehen sind, welche jeweils zumindest teilweise aus einem flexiblen Material gebildet sind und zum Bilden des Aufnahmeraums dichtend miteinander verbunden sind, und wobei sich zu beiden Seiten entlang des Aufnahmeraums erstreckende, stegartige Trägerelemente vorgesehen sind, an denen die den Aufnahmeraum bildenden Profilelemente klemmend befestigt sind.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.

Eine Besonderheit der dargestellten Lichtlinien 1 in
Lichtlinien, die geeignet sind, einer gekrümmten Bahn zu folgen, sind an sich bereits bekannt und beispielsweise in der
In den
Die gewünschte Biegbarkeit der Profilkörper 300 wird dabei dadurch erreicht, dass wie insbesondere in den
Das Prinzip dieser entsprechend geschlitzt ausgeführten Profilkörper 300 ist wie bereits erwähnt bereits aus dem Stand der Technik bekannt. Hier waren dann die weiteren Komponenten des Systems zum Bilden der Lichtlinie, insbesondere die Lichtquellen unmittelbar in dem durch die Profilkörper 300 gebildeten Aufnahmeraum positioniert. Allerdings ist erkennbar, dass in diesem Fall kein geschlossener Aufnahmeraum erzielt werden kann, in dem die weiteren Komponenten des Systems vor äußeren Einflüssen geschützt sind. Insbesondere durch die Schlitze 310 sowie an Stoßstellen zwischen zwei hintereinander angeordneten Profilkörpern 300 kann Feuchtigkeit oder Staub in den Innenraum des Systems eindringen und gegebenenfalls die Lichtabgabe sowie die Funktionalität des Systems negativ beeinträchtigen.As already mentioned, the principle of this
Bei dem in den Figuren dargestellten erfindungsgemäßen System ist deshalb vorgesehen, die Profilkörper 300 in erster Linie als Tragkonstruktion sowie ggf. als mechanischen Schutz für die weiteren Komponenten des Systems zu nutzen, das System allerdings derart auszugestalten, dass durch zusätzliche Maßnahmen eine Abdichtung gegenüber äußeren Einflüssen erzielt wird. Hierzu ist vorgesehen, unabhängig von den Profilkörpern 300 einen allseitig umschlossenen kanalartigen Aufnahmeraum zu schaffen, in dem dann die weiteren Komponenten des Systems, insbesondere die Beleuchtungseinheiten angeordnet sind.In the system according to the invention shown in the figures is therefore intended to use the
Dieser mit dem Bezugszeichen 250 versehene Aufnahmeraum wird dabei im Wesentlichen durch zwei Profilteile gebildet, ein so genanntes Schlauchprofil 200 sowie eine Abdeckung 100. Die Form beider Profilteile 100, 200 kann insbesondere der Schnittdarstellung von
Die Abdeckung 100 weist einen plattenartigen, ebenen Lichtaustrittsbereich 105 auf, über den die eigentliche Lichtabgabe erfolgt und der dementsprechend lichtdurchlässig ausgeführt ist. Zu beiden Seiten dieses plattenartigen Lichtaustrittsbereichs 105 sind dann stegartige Klemmprofile 110 ausgebildet, über die eine dichtende Befestigung der Abdeckung 100 erfolgt.The
Beide Profilteile, also Abdeckung 100 und Schlauchprofil 200 bestehen zumindest teilweise aus einem flexiblen Material, bevorzugt aus einem weichen Kunststoff, wie zum Beispiel Silikon oder dergleichen. Insbesondere die Klemm- und Dichtprofile 110 und 210 sollten dabei zum Erzielen der gewünschten Abdichtung die erwähnte Flexibilität aufweisen. Um jedoch gegebenenfalls einer gekrümmten Bahn der Profilteile folgen zu können, sollte dies vorzugsweise auch für die weiteren Komponenten, also die Bodenwand 201 sowie die Seitenwände 202 des Schlauchprofils 200 sowie für die Lichtabstrahlfläche 105 der Abdeckung 100 gelten. Die Ausgestaltung beider Profilteile 100, 200 in Form flexibler Elemente bringt darüber hinaus auch den Vorteil mit sich, dass beide Profilteile 100, 200 derart verformt beziehungsweise gebogen werden können, dass sie vor ihrer Montage auf größere Rollen oder dergleichen aufgewickelt und dementsprechend in einer beliebigen Länge zu ihrem Einsatzort transportiert werden können. Erst dann werden sie im Rahmen der Montage des Systems auf eine Länge, die vorzugsweise der Gesamtlänge der Lichtlinie 1 entspricht, abgeschnitten, sodass sich beide Profilteile 100, 200 lückenlos über die gesamte Länge des Systems hinweg erstrecken. Durch dieses Prinzip, welches beispielsweise auch bereits in der
Bevor die erfindungsgemäße stirnseitige Abdichtung des Systems erläutert wird, soll zunächst jedoch noch beschrieben werden, in welcher Weise Abdeckung 100 und Schlauchprofil 200 miteinander verbunden und an den als Tragstruktur dienenden Profilkörpern 300 befestigt werden. Hierfür sind speziell ausgestaltete stegartige Trägerelemente, sog. Randprofile 150 vorgesehen, die in spezieller Weise mit den verschiedenen Komponenten des Systems zusammenwirken. Die Ausgestaltung dieser Randprofile 150 kann insbesondere der Schnittdarstellung von
Dabei ist zunächst erkennbar, dass die Trägerelemente 150 einen in der Darstellung nach unten offenen ersten Einführungsbereich 155 aufweisen, der seitlich einerseits von einer Seitenwand 151 des Trägerelements und andererseits von einem dieser Seitenwand 151 gegenüberliegenden Steg 152 begrenzt wird. Der Steg 152 ist hierbei derart ausgeführt, dass der Einführungsbereich 155 eine seitliche Erweiterung 156 aufweist. Dieser Einführungsbereich 155 dient dann dazu, die Trägerelemente 150 auf die Seitenwände 302 der Profilkörper 300 aufzuschnappen. Diese Seitenwände 302 greifen dabei mit ihren oberen Endbereichen in den Einführungsbereich 155 ein, wobei nach innen ragende Noppen oder Ausprägungen 303 (siehe
Zusätzlich weist das Randprofil 150 zwei nach oben geöffnete Klemmbereiche auf, einen seitlich von dem Einführungsbereich 155 angeordneten ersten Bereich 160 sowie einen oberhalb von dem Einführungsbereich 155 liegenden Bereich 165. Beide weiteren Klemmbereiche 160 und 165 weisen zusätzlich zumindest eine nach innen ragende Rastnase 161 beziehungsweise 166 und 167 auf, durch welche eine klemmende Halterung mit den Profilteilen 100 bzw. 200 erzielt wird. Wie nämlich insbesondere der Darstellung von
Bei einer Montage des Systems werden dann bevorzugt zunächst die Randprofile 150 mit dem Schlauchprofil 200 gekoppelt beziehungsweise verklemmt. Anschließend können die Beleuchtungseinheiten 40 in dem Schlauchprofil positioniert werden, wobei die hierdurch gebildete Einheit dann beispielsweise an den Profilkörpern 300 befestigt werden kann. Im abschließenden Montageschritt wird dann die Abdeckung 100 auf die Anordnung aufgeschnappt, wobei gegebenenfalls auch zuerst das Anbringen der Abdeckung an den Randprofilen 150 erfolgen könnte und erst nachfolgend die hieraus resultierende Anordnung dann an den Profilkörpern 300 befestigt wird.When mounting the system, the edge profiles 150 are then preferably first coupled or clamped to the
Wesentlich hierbei ist, dass also die Randprofile 150 nahezu sämtliche Komponenten des Systems halten und insbesondere über diese Randprofile 150 dann die Befestigung an weiteren Tragsystemen (wie hier den Profilkörpern 300) oder Tragstrukturen erfolgt. Wie nachfolgend noch erläutert wird, eröffnet diese Ausgestaltung die Möglichkeit, gegebenenfalls auch alternative Lösungen zur Montage des Lichtliniensystems an einer Wand oder Decke zu realisieren.It is essential here that therefore the edge profiles 150 hold almost all components of the system and in particular via these
Die bislang beschriebenen Maßnahmen dienten also dazu, einen über die gesamte Länge des Systems hinweg umseitig abgedichteten Aufnahmeraum 250 für die Beleuchtungseinheiten 40 zu schaffen, sodass die hierdurch realisierte Lichtlinie beispielsweise den Anforderungen einer so genannten höheren Schutzart genügt, also beispielsweise vor dem Eindringen von Staub und/oder Feuchtigkeit geschützt ist. Selbstverständlich ist allerdings noch ein stirnseitiges dichtendes Verschließen des Aufnahmeraums 250 erforderlich, wobei dies erfindungsgemäß durch speziell ausgestaltete und in spezieller Art und Weise befestigte Stirnteile erfolgt, die nachfolgend näher beschrieben werden sollen.The measures described thus far served to create a circumferentially sealed over the entire length of the
Eine erste Besonderheit der erfindungsgemäßen, mit dem Bezugszeichen 50 versehenen Stirnteile besteht dabei darin, in welcher Weise diese an den den Aufnahmeraum 250 bildenden Komponenten, also der Abdeckung 100 und dem Schlauchprofil 200 befestigst sind. So sind die Stirnteile 50 unmittelbar an zumindest einem der beiden Profilteile 100, 200 fixiert, vorzugsweise jedoch an beiden. Das Fixieren der Stirnteile 50 an den Profilteilen 100 beziehungsweise 200 bringt dabei den Vorteil mit sich, dass die Stirnteile 50 etwaige Längenänderungen des Aufnahmeraums 250, die durch Temperaturschwankungen auftreten können, mit vollführen können. Trotz allem wird eine vollständige Abdichtung des Aufnahmeraums 250 erzielt.A first special feature of the invention, provided with the
Dabei ist zunächst vorgesehen, dass die Stirnteile 50 mit dem Schlauchprofil 200 über eine Schraubverbindung verbunden werden. Wie beispielsweise anhand von
Dieses besteht dabei zunächst aus einem Blechteil 60, welches das zentrale Trägerelement des Stirnteils 50 darstellt und einen plattenartigen Bereich 61 aufweist, der hinsichtlich seiner Form der Querschnittsform des Schlauchprofils 200 beziehungsweise des Aufnahmeraums 250 entspricht, also leicht trapezartig ausgeführt ist. An den vier Seitenwänden des Blechteils 60 sind jeweils dem Aufnahmeraum 250 zugewandte Laschen 62 bis 64 ausgebildet, wobei die Seitenlaschen 62 sowie die Bodenlasche 63 im befestigten Zustand die Seitenwände 202 beziehungsweise die Bodenfläche 201 des Schlauchprofils 200 übergreifen und dieses dementsprechend stabilisieren bzw. von außen abstützen. Hierdurch ergibt sich keine Notwendigkeit für eine zusätzliche Verbindung zwischen Stirnteil 50 und Schlauchprofil 200 im Bereich der Wände 201, 202, da trotz der Flexibilität nicht die Gefahr besteht, dass die Wände des Schlauchprofils 200 entsprechend seitlich auswandern und hierdurch die Dichtwirkung aufgehoben wird.This consists initially of a sheet metal part 60, which is the central support member of the
Das dichtende Zusammenwirken zwischen Stirnteil 50 und den stirnseitigen Flächen des Schlauchprofils 200 wird dabei durch ein zusätzliches Dichtelement 70 erzielt, welches insbesondere in den
An der dem Dichtelement 70 gegenüberliegenden Seite des Blechteils 60 ist weiterhin ein zusätzliches Halterungselement 80 angeordnet, welches über eine Nietverbindung bestehend aus drei Nieten mit dem Blechteil 60 verbunden ist. Das Halterungselement 80 weist dabei einerseits einen unteren trog- oder topfförmigen Aufnahmebereich 81 auf, der der Lagerung eines gummiartigen Dichtelements 65 dient. Wie nämlich erkennbar ist, sind sowohl in dem Halterungselement 80 als auch in dem Blechteil 60 sowie dem Dichtelement 70 kreisförmige Durchführungsöffnungen 66, 75, 82 ausgeführt, durch die das Hindurchführen von Kabeln in den Aufnahmebereich 250 ermöglicht wird. Das von dem Halterungselement 80 gehaltene gummiartige Dichtelement 65 soll hierbei für den Fall, dass Leitungen hindurchgeführt werden, für die entsprechende Abdichtung sorgen und ist dementsprechend hierfür mit geeigneten Manschetten oder dergleichen ausgeführt.On the side opposite the sealing member 70 side of the sheet metal part 60, an
Oberhalb des Bereichs 81 zur Aufnahme des Dichtelements 65 ist dann eine Blattfeder 85 ausgebildet, über die die Halterung eines zusätzlichen Bauteils, nämlich eines so genannten Dichtwinkels 90 erfolgt. Dieser Dichtwinkel liegt einerseits an der Rückseite des Blechteils 60 an und wirkt mit einem abgewinkelten Vorsprung 91 mit der Blattfeder 85 zusammen. Diese fixiert also den Dichtwinkel 90 an dem Blechteil 60. Gleichzeitig liegt der Winkel mit einem oberen Steg 92 flächig auf dem Steg 72 des Dichtelements 70 auf. Wie insbesondere in
Nachdem also wie zuvor beschrieben das Schlauchprofil 200 an den Randprofilen 150 befestigt wurde und die Leuchtmittel 40 in dem Aufnahmeraum 250 positioniert wurden, werden dann die Stirnteile 50 in der erfindungsgemäßen Weise mit dem Schlauchprofil 200 verschraubt. Im abschließenden Arbeitsschritt wird dann die Abdeckung 100 von der Oberseite her auf die Randprofile 150 aufgeschnappt, wobei einerseits hierzu in Längsrichtung die klemmende und dichtende Verbindung erzielt wird, gleichzeitig an den Stirnseiten die Abdeckung 100 mit der klebenden Oberseite des Stirnteils 50 verbunden wird. Insgesamt wird durch diese Maßnahmen also ein vollkommen umschlossener Aufnahmeraum 250 geschaffen, in den das Eindringen von Schmutz und/oder Feuchtigkeit verhindert wird. Trotz allem ist aufgrund der beschriebenen Maßnahmen sichergestellt, dass die den Aufnahmeraum und damit insgesamt die Lichtlinie bildenden Komponenten derart flexibel ausgeführt sind, dass die entstehende Lichtlinie gegebenenfalls auch einer gekrümmten Bahn folgen kann.Thus, as described above, the
Wie oben geschildet stellen die Randprofile 150 die zentralen Halterungen der Komponenten des Systems dar. Die geschlitzten Profilkörper 300 hingegen sind bei der in den
Anstelle der geschlitzten Profilkörper 300 kommen hierbei bügelartige Halteelemente 400 zum Einsatz, die in regelmäßigen Abständen entlang der Randprofile 150 positioniert werden. Die Verbindung mit den Randprofilen 150 erfolgt in gleicher Weise wie auch bei den oben beschriebenen geschlitzten Profilkörpern 300, das heißt, auch die bügelartigen Halteelemente 400 weisen an nach oben ragenden Armen 410 jeweils entsprechende Vorprägungen beziehungsweise Noppen 411 auf, über die eine Verrastung mit den Randprofilen 150 erfolgt.Instead of the slotted
Die Halteelemente 400 sind dabei an ihren Seitenarmen 410 derart ausgeführt, dass diese entsprechend dem Doppelpfeil in
Insgesamt wird also ein System zum Bilden einer Lichtlinie geschaffen, welches auch erhöhten Anforderungen hinsichtlich der Abdichtung gegenüber äußeren Einflüssen genügt. Gleichzeitig eröffnet der erfindungsgemäße Aufbau unterschiedliche Möglichkeiten zur Montage des Systems, sodass dieses äußerst vielseitig und flexibel einsetzbar ist.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.
