Description

The invention relates to a light insert, which is intended and set up for arrangement on a lighting system, with an insert body which is designed as a hollow profile and extends essentially in one plane between its two end regions, wherein at least one lamp can be arranged or is arranged in the insert body , which emits a light yield generated during operation of the lamp in the direction of a light outlet of the insert body. In addition, the invention relates to a method for producing such a light insert and finally also to an illumination system which is provided with a plurality of such light inserts.

Such light inserts are known in principle and are used, for example, in so-called profile lights, which are used not only indoors but also outdoors. However, in order to be able to use the luminaires in question there, the profiles must have a certain resistance to the ambient conditions prevailing there. In the case of electrical equipment, such as the lights in question, the suitability for various environmental conditions is described in suitable protection classes, which in turn are expressed in so-called IP codes. The IP65 protection class is intended for the lights used, which means that the respective light must be dust-tight and protected (tight) against water jets. With conventional lights, this is achieved by gluing or encapsulating (encapsulating the converters and cables required for LED lighting) of metallic profiles. However, this means that subsequent maintenance (replacing the circuit board, replacing the converter) is no longer possible.

In the U.S. 2017/0101046 A1 for example, a modular lighting device is also described. Described here is a housing with an elongate shape and housing end pieces that are attached to the housing. In the U.S. 2017/0101046 A1 is also described to equip the housing with ribs to increase its surface and improve cooling. A lens is attached to the housing in such a way that the interface between the lens and the housing is airtight.

the U.S. 2017/0198889 A1 describes light strips that can be waterproof or water-resistant. It describes, for example, providing a male or female end connector at the ends of a light strip in order to connect the light strip directly or indirectly to other light strips.

In the US 2010/0027266 A1 discloses a lighting device having a heat-dissipating substrate made by extrusion of aluminum, protective covers attached to both ends of the substrate, and a transparent plate attached to the top of the substrate. Good heat dissipation and a long service life should be made possible. Furthermore, it is described that at least one of the protective covers has a through-opening for establishing an electrical connection to an external power supply.

the DE 10 2008 016 697 A1 describes a lamp with a lower housing part and an upper housing part. Forming the lower part and upper part of the housing as extruded profiles is described. It is also described how to close the lower and upper housing parts after they have been assembled at the ends by means of end caps, with one end cap also being able to have a power supply. Forming the lower housing part with cooling fins is also described. Fastening screws reach through holes in the end caps.

DE 10 2006 047 874 A1 describes a lamp, in particular a splash-proof wall or ceiling lamp, with a housing that can be composed of a base part and a dome part in a closed manner. It describes molding the base part and the dome part from a thermoplastic material.

There is therefore the task of providing an improved light insert that can be produced at a reasonable cost for the possible use of lights in dusty or damp environments, which on the one hand has the necessary tightness with respect to the environment and on the other hand requires little maintenance of lights fitted with the light insert is permitted.

According to the invention, this object is achieved by a light insert having the features of claim 1 . In the solution, the light insert is provided in such a way that the end regions of the insert body can be closed or closed by detachably connecting them to an end piece, and at least the insert body is made of a thermoplastic material. Due to the fact that the insert body can be closed by detachably connecting it to end pieces, which are arranged in the relevant area but can be removed just as easily from this, the interior of the insert body of the light insert is in principle accessible for maintenance at any time, so that the circuit board or converter, for example, can simply be replaced can become. At the same time offers the execution of the insert body from a thermoplastic material provides the necessary tightness in order to be able to withstand the ambient conditions and is lighter than a metallic profile and, moreover, can be produced easily with little effort. Finally, the end pieces mentioned can be arranged in a simple manner on the respective insert body and, if necessary, also removed again. As mentioned, at least the insert body is made of the thermoplastic material, although this can advantageously also apply to one or more of the end pieces in designs of the light insert.

Further advantageous features are contained in the dependent claims.

In an embodiment of the light insert according to the invention that is easy to handle and particularly advantageous from an aesthetic point of view, the end pieces can have a cross section that changes over the height of the insert body and tapers in the direction of the light exit. As a result, on the one hand such end pieces can be arranged easily and purposefully on the associated end region, and on the other hand the end pieces in this embodiment are practically invisible to an observer when viewed from below.

In order to hold the end pieces firmly and securely on the respective insert body, in an expedient embodiment of the light insert according to the invention, the respective end piece can be held in a closed position on the associated end region of the insert body by at least one fastening means.

Advantageous developments of the light insert according to the invention, which are easy to implement, can consist in the fastening means being formed by at least one or a plurality of screws which, in a closed position of the respective end piece, engage in an associated engagement on the insert body, the engagement being carried out by a is formed with the insert body in one piece, drawn screw channel. In the closed position mentioned, the respective end piece is arranged on the insert body in such a way that it closes an opening located in the end region of the hollow profile. The at least one fastener expediently engages in the closed position first through a passage on the end piece and then in the engagement opposite this passage on the insert body in the closed position, which is designed as a drawn screw channel in one piece with the insert body formed from the thermoplastic material.

In order to be able to meet the tightness requirements in a suitable manner and with little effort, it is provided in an advantageous embodiment of the light insert according to the invention that a sealant can be arranged or is arranged on a peripheral edge region of at least one of the end pieces, which sealant can be arranged when the end piece is arranged the insert body is located between this and an edge region of the end region of the insert body. The sealant can advantageously be arranged on several, in particular on all, end pieces.

On profile lights that are provided with light inserts, the current-carrying lines to which converters for supplying circuit boards and lamps are connected should again be largely hidden from view by viewers outside of the light insert, which is why in an advantageous embodiment of the light insert according to the invention at least one of the end pieces has an access device in a region facing away from the light outlet of the insert body, which leads a cable into an interior space of the insert body. The access device can be provided in such a way that, on the one hand, a partial line is routed, for example, to a converter inside the insert body, and, on the other hand, another partial line leaves the access device in the direction of a further, following access device, so that several light inserts arranged together can also be opened can be electrified in this way. The wiring itself can be routed behind the insert body in the viewing direction, for example along its longitudinal extension, so that it cannot be seen by onlookers.

In a further development of the light insert, a particularly preferred embodiment of the access device can be arranged on the side of the insert body facing away from the light exit and eccentrically with respect to its transverse extension. In principle, however, other arrangements of the access device on the end pieces are also conceivable.

In order to be able to easily remove or displace unwanted foreign bodies or moisture from the interior of the insert body, for example during cleaning or maintenance processes, at least one of the end pieces of the light insert according to the invention is provided with a closable, operable passage, which in its open position access to the interior of the hollow profile, ie the relevant cavity, releases. It's included, for example conceivable, by means of reaching through, to flush or flood the cavity of the hollow profile with air or an inert gas. For this purpose, the reach-through that can be actuated is designed as a valve.

An expedient embodiment of a light insert according to the invention can basically have a shape in which a section of the light insert facing the viewer has a wider cross section than a section facing away from the viewer, whereby the latter shades the former in a certain way. In this case, the insert body can have an area with a reduced cross section, which forms the area of the insert body that faces away from the light outlet. However, this area with a reduced cross-section can also owe its dimensioning, for example, to the accommodation of electronic components.

A preferred embodiment of the light insert according to the invention can provide a holding means in the interior of the insert body and be set up to hold electrical and/or electronic lighting components in a fixable or fixed position. This can be provided in particular by projections or grooves, which can be realized in a simple manner with the material selection according to the invention of the light insert made of a thermoplastic material and the associated production of the insert body.

In a further preferred embodiment of the light insert according to the invention, the thermoplastic material can be translucent or transparent and can be configured as polycarbonate, polypropylene, polyvinyl chloride or polymethyl methacrylate. As a result, a light exit is already provided at any desired point of the insert body, which means that the insert body as a hollow profile can completely and in particular seamlessly enclose its own cavity, so that no further measures are required at this point with regard to the protection class to be achieved.

In an expedient development of the light insert according to the invention, at least one first support part can be assigned to it, which has a higher rigidity than the light insert itself and which itself can be arranged or is arranged in a section within the insert body and in the relevant section with its contour the profile there at least partially modeled or replaced, or that at least one second support part is assigned to it, which has a higher rigidity than the light insert itself and which at least partially encloses or accommodates the insert body. In the case of the support parts mentioned, the ordinal numbers only serve to distinguish them and have nothing to do with a sequence or ranking. The first support part is one that can be introduced or inserted into the cavity of the insert body and is able to imitate or even replace its contour, but in particular to support its structure from the inside and thereby make it more torsion-resistant. The inclusion of the light insert in a second support part can also serve the purpose of supporting its structure and can be designed, for example, in a lattice-like frame with a large mesh size. However, other configurations are also conceivable. It is also conceivable that both types of support parts are arranged on or with the light insert at the same time.

In an advantageous development, a plurality of light inserts can be arranged on a support structure and in this way can be combined to form an illumination system with an optionally variable number of light inserts. Due to the structure of the light inserts, a support structure of the desired size can be provided with the number of light inserts then required.

Preferably, an access device allowing the cabling of the respective light insert can be provided and set up on a plurality of end pieces assigned to different insert bodies, wherein the plurality of access devices, which are assigned to a common lighting system, can be connected or are connected to one another via a guide means in such a way that the cabling can be guided using the guide means along an extension of the light inserts.

The aforementioned object is also achieved while maintaining the above reasoning by a method with the features of claim 14 for producing a light insert according to the invention with the aforementioned features, wherein the light insert in question is provided with an insert body made of a thermoplastic material, which is designed as a hollow profile which extends between its two end regions essentially in one plane, at least one lamp being arranged in the insert body, which emits a light output generated during operation of the lamp in the direction of a light outlet of the light insert or of its insert body.

With this method, on the one hand, already in the production of insert bodies of light inserts for the arrangement and the Hal th of the end pieces necessary interventions for the fasteners, such as external threads for engaging screws, bring in, so that a drawn screw channel is already created here and such a subsequent processing of the insert body can be avoided. On the other hand, when or shortly after the still unfinished insert bodies are removed from the tool, they can be tailored to a desired length.

The above configurations and developments can be combined with one another as desired, insofar as this makes sense. Further possible configurations, developments and implementations of the invention also include combinations of features of the invention described above or below with regard to the exemplary embodiments that are not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

Identical or functionally identical elements and devices have been provided with the same reference symbols in all figures—unless otherwise stated.

First referring to the 1 and 2 a light insert, designated as a whole with 10, is provided and set up for arrangement on a lighting system 100, with an insert body 20, which is designed as a hollow profile with a cavity 22 and extends between its two end regions 34, 35 essentially in one plane, where in the insert body 20 at least one in the 1 not recognizable illuminant 40 is arranged, which emits a light output generated during operation of the illuminant 40 in the direction of a light outlet 28 of the insert body. The light outlet is located on the insert bodies in the lower area of the representation for the viewer. In the representation of 1 can also be seen that the end portions 34, 35 of the insert body 20 are each closed by detachable connection with a respective end piece 24, 25, the insert body 20 and the end pieces 24, 25 are each formed from a thermoplastic material. At the end pieces 34 arranged for the viewer in each case on the right-hand end regions 34 there is an access device 50 for two-sided feeding into the 1 and 2 Wiring 56, not shown, is provided for reasons of clarity.

The in the 1 and 2 The light inserts 10 arranged one behind the other in the direction of their longitudinal extension are as such part of a lighting system 100.

In the 3 and 4 one recognizes a light insert 10 with its insert body 20 and at its end regions 34, 35 arranged end pieces 24, 25 in isolation in two different perspective views, each beginning with one of the end pieces behind which the insert body extends. It is further shown that while one end piece 24 is provided with the access device 50, the other end piece 25 is provided with an actuatable passage 38 in the form of a valve. You can also see in the 3 and 4 The fact that the cross section of the insert body changes with its height speaks for having a constriction at a stage 29 . At the level of this constriction, there are engagement points 26 on the insert body for engaging screw-type fasteners (not shown) that hold the end pieces 24, 25 on the insert body 20 in their position of use.

In the 5a and 5b one recognizes a single light insert 10 for arrangement on a lighting system 100, wherein in the 5a the light insert 10 is shown in a plan view from above, in which it can be seen that the access device 50 is arranged facing the viewer on the right end piece 24 arranged for the viewer in the right end area 34 . This access device 50 is designed in the manner of a double-accessible T-piece, the two accesses of which are provided opposite one another but eccentrically with respect to a center line extending in the longitudinal direction of the insert body 20 . In the 5a and 5b cabling 56 (not shown) is fed to the access device 50 and screwed to its sealed sheathed cable by means of cable glands 52, so that the cabling 56 is protected from mechanical influences, dust and moisture and is connected to the access device 50. These screwed cable connections 52 can be provided as so-called PG screwed cable connections with a steel armored pipe thread and are designed, for example, with IP65 protection, and are able to protect the cabling 50 from dust and water jets. Next you can see in the 5a clearly the step 29 formed by the constriction of the cross section of the insert body 20 to about two thirds of the height of the insert body. Only in the sectional view of FIG 5b The fact can be seen that in an upper area of the insert body 20 facing away from the light exit 28 there is a circuit board 30 which carries illuminants 40 designed as light-emitting diodes which emit their light output in the direction of the light exit 28 of the light insert 10. Furthermore, it can also be seen that a converter 32 is arranged on the circuit board, facing away from the light outlet, and is held on the circuit board 30 by a fastening means that extends through the circuit board 30 .

In the 6a and 6b a single light insert 10 is again shown for arrangement on an illumination system 100, the planar side view of FIG 6a in contrast to the representation of 5b is not cut. Otherwise, the two figures just mentioned show essentially the same facts, with the access device 50 being arranged on the end piece 24 in the end region 34 on the right for the viewer. It can also be seen that the mentioned access device 50 is arranged facing away from the light outlet 28 of the insert body 20 of the light insert 10, and moreover that the step 29 is provided in the upper section of the insert body 20, more precisely at about two thirds of its height , and that a flange-like overhang 12 is provided along the insert body 20 on the wall region terminating the insert body 20 at the top, which extends over its entire length. This circumstance is illustrated by the cut representation of the 6b further clarified. In this drawing figure one can see the cavity 22 formed by the insert body 20, in which the volume enclosed by the insert body 20 is completely enclosed. Next you can see in the 6b the stage 29 of the insert body 20 and the eccentricity of the arrangement of the access device 50. The means of in the 6b Wiring lines 56 that are not shown are electrically connected to the contacts 31 that are located on the converter 32 . Finally, you can tell by the in the 6b insert body 20 shown further that below the stage 29 areas are provided in which on both sides there are interventions 26 designed as screw channels 27, which are introduced into the structure of the insert body 20 of the light insert 10 during the production thereof.

the 7 shows an insert body 20 of the light insert 10 without further additional installations in a planar sectional view in order to be able to explain features of the insert body 20 better. The wall section closing off the insert body 20 at the top is provided with a projection 12 along its longitudinal extension on both sides of the insert body 20 . Furthermore, the step 29 formed by the constriction of the cross section of the insert body 20 and the screw channel 27 designed as interventions 26 can be seen on both sides. The cavity 22 of the insert body 20 is closed off at the bottom by the light exit 28 . In the vertical extension of the insert body 20, a holding means 14 is provided approximately at the level of the step 29, by means of which the circuit board 30 (not shown) can be fixed in the cavity 22 of the hollow profile of the insert body 20. For this purpose, two mutually parallel wall sections 16a, 16b projecting from the opposite side walls of the insert body 20 form a groove 18, in which the circuit board 30 mentioned, which carries the lamps 40, also not shown, and the converter 32. Due to the arrangement described, the two grooves 18 located on the opposite side walls of the insert body are at the same height and form a holding means 14 with the wall sections 16a, 16b that delimit them Wall sections 16a, 16b would only be formed on one side.

In order to be able to illustrate the function of the projection 12 formed on both sides at the upper end of the insert body, the light insert 10 is received with its insert body 20 on a support part 60 and is held there by means of a holding member formed by a clamp 62 . The representation from the 7 The corresponding insert body 20 is held on the support part 60 in that the clip 62 fixed to the support part engages behind the overhang 12 of the insert body 20 with a spring-loaded projection and accordingly secures it against movement out of the support point 60, with a folded area of the clip 62 is supported on the side walls of the upper area of the insert body 20 in such a way that it is also secured against transverse movements within the support part 60 .

In the 8a until 8f , 9a until 9f and 10a to 10f different end pieces 24, 25 for arrangement on the insert body 20 of the light insert 10 are shown. The show 8a until 8f the end piece 25 provided for arrangement in the end region 35 of the insert body 20. This can be seen in the perspective view of FIG 8a on the inward-facing side of the end piece 25, on the one hand, the sealing means 42 running around the edge, then the valve 39 forming an actuatable passage 38 and the passage 36 located below the step 29 of the insert body 20, which is designed to pass through the engagement 26 of the insert body 20 engaging fastening means, not shown, are provided which hold the end piece 24, 25 in question on the insert body 20 in this way. The features mentioned can be recognized at least partially in each case 8b , 8d and 8e , the last one being a sectional side view along line CC of FIG 8d represents. In the 8c the narrowing of the cross section of the end piece 25 in the direction of the light outlet 28 of the insert body 20 can be understood particularly well when the relevant end piece 25 is arranged on the insert body 20 . Finally, you can see the top view of the tail in the 8f very well that the contour of the insert body 20, in particular with regard to the stage 29 there, is modeled with the end piece 25.

In the 9a until 9f as well as the 10a until 10f end pieces 24 are shown for arrangement in the end region 34 of the insert body 20, the representation and their indexing being those of 8a until 8f is equivalent to. Correspondingly, one recognizes the end pieces 24 in these drawing figures on the inner edge surrounding sealing means 42, the passage 36 and the access devices 50 provided according to the invention on the respective end piece 24. The end pieces 24 of the 9a until 9f differ from those of 10a until 10f by the fact that in the 10a until 10f an end piece 24 with only one-sided access device 50a is provided, which is used when arranging a plurality of light inserts 10 on an illumination system 100 as a light inserts 10 arranged in a row delimiting end piece 24 .

Now the 11a until 11c turning, one recognizes there in the 11b and 11c a lighting system 100 formed from three light inserts 10 arranged one behind the other in a planar side view ( 11b ) or in plan view from above ( 11c ), In which the light inserts 10, of which a single in the 11a is shown, are electrically connected to one another by the wiring 56 connected to the access devices 50 by means of the sleeves 52 . Sections of wiring 56 may differ are in turn connected to each other by couplings 54 coupled together by connectors 53 located at end portions of the cabling 56. The light inserts 10 used in the lighting system 100 each have the insert body 20 described above, which is closed off in one end area 35 by an end piece 25 , while the other end area 34 is closed off by an end piece 24 . Here you can see in the 11b and c in the lighting system 100 at the right end for the viewer that here an end piece 24 is arranged, which the representation from the 10a until 10f corresponds, ie an end piece 24, which only has a one-sided access device 50a.

Finally shows the 13 a symbolic representation of a method according to the invention for producing a light insert 10, which is provided with an insert body 20, which is designed as a profile 22, and which extends essentially in one plane between its two end regions 34, 35, wherein in the insert body 20 at least a light source is arranged. A light yield generated during operation of the illuminant 40 is emitted in the direction of a light outlet 28 of the light insert 10 or of its insert body 20 . That in the 13 The method shown is characterized by the following steps: in step S1, a tool is provided in which the plastic used for production is melted and homogenized; in step S2, the melted and homogenized plastic emerges from the tool, cools down and solidifies in a calibration under air or vacuum, channels for the engagement of fastening means being introduced in the position of use of the insert body; finally, in step S3, the insert body is pulled off the tool and then cut to a desired length.

Although the present invention has been described above on the basis of preferred exemplary embodiments, it is not limited thereto but can be modified in a variety of ways. In particular, the invention can be changed or modified in many ways without departing from the essence of the invention.
