The system has a beam profile (18) whose profile ends are designed for connection to adjacent construction elements such as carrier (12,14) and several light modules (20) which are formed on beam profile. The electrical leads (26,28) are extended in a direction of a profile end. The beam profile is formed as a hollow profile whose rear side is provided with a recess (22). A clip is clipped to rear side and the light module is pressed into the recess, such that the lead is laid within the beam profile and equipped with a connector (30) at its end. An independent claim is included for ceiling structure.

Description

The present invention relates to a luminaire mounting system for buildings according to the preamble of claim 1.

Lighting systems for buildings must meet various requirements. On the one hand, the rooms must be lit as well as possible according to their use, on the other hand, the lighting system must work energy-efficiently. In addition, aesthetic considerations play a role in the design of the lighting.

These requirements are also becoming increasingly important in public buildings such as parking garages. The lighting here must not only meet legal requirements, but also take into account the users' sense of security. Due to their brightness with low power consumption, fluorescent tubes have hitherto been preferred for illuminating the parking decks and access roads of multi-storey car parks. The luminaire modules with the tubes held therein are simply attached from below to beam profiles, which run transversely between the load carriers of the ceiling of the parking deck. The supply cables are routed along the beam profiles.

Such luminaire mounting systems are useful, but not aesthetically appealing. In addition, fluorescent tubes are increasingly being replaced by LED luminaires, which are even more energy-efficient, have a longer service life, and offer even more design possibilities. Often, a larger number of LED lights are integrated in a lighting module. This offers new possibilities of assembly, which have not yet been sufficiently used. In addition, it is desirable to install the lighting module as quickly and easily as possible without having to involve an electrician.

The object of the present invention is therefore to provide a luminaire mounting system for buildings, which is aesthetically pleasing than the previously known lighting systems, but is easier to install.

This object is achieved by a luminaire mounting system with the features of claim 1.

In the luminaire mounting system according to the invention, the beam profile is a hollow profile, in which the one or more lighting modules are integrated and exposed only at recesses of the profile. For this purpose, the beam profile is open at its rear and has on the opposite front the recesses for the lighting modules. The respective lighting module can thus be inserted from the open rear side into the recess provided for this purpose.

In its mounting position, the luminaire module is secured by a clip, which is clipped into the open back of the profile and pushes the luminaire module into the recess. The attachment of the clip can be done without the aid of a tool, so that the assembly is very easy. The same applies to the removal of the lamp module, since the clip can be designed so that it can be easily detached from the hollow profile by hand.

It is understood that the number of luminaire modules in the beam profile can be varied as needed. A single luminaire module can be used, which is inserted into its recess at any point of the length of the beam profile, or a plurality of luminaire modules can be arranged along the beam profile and interconnected by their supply cables, so that they are connected in series. Merely for reasons of linguistic simplicity, reference will be made to a single luminaire module in the following description.

The supply cable for the supply of the luminaire module is laid within the beam profile and equipped at its end with a connector. The supply cable can thus be easily connected to a corresponding power cord or to a connecting cable of another lamp module. Again, this is done without tools and can be done without expert knowledge and skills.

The luminaire module, together with its supply cable, is completely integrated in the beam profile, and the luminaire only shows the part that lies in the recess. The rest is hidden within the hollow profile. This is visually appealing than the known systems in which the luminaire module is applied to the outside of the beam profile.

It is also possible to expand the luminaire mounting system according to the invention so that a plurality of beam profiles are subsequently installed to each other, for example, in the adjacent spaces between the load carriers of the ceiling of the building. The load carriers are provided for this purpose with recesses through which the leads for connecting two adjoining beam profiles are guided on the opposite sides of the load carrier. In this way, a greater distance within a room can be illuminated by series-connected lighting modules.

It is understood that the beam profiles are not only suitable for mounting between two adjacent load carriers, but they can also be connected to other structural elements, such as posts, walls or the like. Furthermore, the luminaire mounting system according to the invention for use in a particular type of buildings is limited, so in particular not only for use in parking garages, but is also suitable for use in warehouses or the like.

According to a preferred embodiment of the invention, the lamp module has a stop which is pressed by the pressure of the clip from the inside of the beam profile against the edge of the recess.

This stop forms a resistance when inserting the lamp module into the recess, which prevents the module from slipping through the recess, thus giving it a secure hold in the hollow profile. When the clip is inserted, it presses the luminaire module against the stop against the edge of the recess.

According to a preferred embodiment, this stop of the luminaire module is designed as a circumferential gradation.

According to a further preferred embodiment, the boundary edges of the open rear side of the beam profile for receiving the ends of the clip are pulled inwards.

According to a further embodiment of the invention, the clip is approximately U-shaped and has a central web for resting on the back of the lamp module and two resilient legs, leave their ends clipped into the boundary edges of the open back of the beam profile.

Further preferably, the profile ends of the beam profile are provided with flanges for connection to the adjacent construction elements.

Further preferably, the beam profile is arranged horizontally, such that its open rear side facing upward and provided with the recess front side forms the underside of the beam profile.

This mounting position corresponds to a ceiling lighting system in which the beam profile is arranged in a ceiling, for example, between two load carriers.

According to another aspect of the present invention, a ceiling structure is claimed in a building having horizontal parallel load beams and at least one luminaire mounting system of the type described above, the beam profile of which connects two load beams provided with apertures for passing the ends of the electrical feeder cables.

Preferably, this ceiling construction according to the invention comprises at least two luminaire mounting systems according to the present type, the beam profiles are aligned with each other on two opposite sides of a load carrier and their luminaire modules are connected by their feed cable feeding each other, which are guided through the openings in the load carriers and their ends are plugged together.

Fig. 1 is a side view of a portion of a ceiling structure 10 in a building, for example in a parking garage. In cross section load carrier 12,14 are shown, which are formed as a double-T-carrier and spaced parallel to each other. Between the webs 16 of these beams 12,14 a beam profile 18 is suspended, which connects the carrier 12,14 and is perpendicular to these. In this beam profile 18 is a hollow profile, which is formed from a folded steel sheet and the top is open. The shape of this beam profile 18 will be explained in more detail with reference to the following figures.

In the beam profile 18, a lamp module 20 is added, which serves to illuminate the space below the beam profile 18. For this purpose, the beam profile 18 is provided on its underside with a rectangular recess approximately in the middle of its longitudinal extent. In this recess, the lamp module 20 is inserted so that the bulbs can radiate the light down freely.

In detail, the lamp module 20 comprises an outer housing 24, which is formed compact and resistant and protects the lamps contained therein. On the underside, this housing 24 can be closed by a transparent cover. The supply of the luminaire module 20 with electricity is done by supply cable 26,28, which extend on both sides of the lamp module 20 respectively in the direction of one end of the beam profile 18. They have at their ends connector 30, which allow to connect the respective supply cable 26,28 to another cable, so that a connection to a network connection or another lighting module can be created.

This power connector is in Fig. 1 shown schematically and provided with the reference numeral 32. It is located on the left side of the left load carrier 12. The load carrier 12, at the web 16, the left end of the beam profile 18 is connected, is provided with an opening, not shown, through which a connection cable 34 is moved from the power supply 32 ago. At this connection cable 34, the supply cable 28, which extends from the lamp module 20 ago to the left, connected.

To the right side of the right load carrier 14 another identical beam profile 18 is connected, such that its longitudinal axis is aligned with the above-described beam profile 18 between the load carriers 12,14. Also, the right load carrier 14 is provided at its web 16 with openings, which allows a passage of a cable. The right-hand feed cable 26, which extends from the luminaire module 20, is made longer than the left-hand feed cable 28, which leads to the mains connection 32. Thus, the right supply cable 26 can be guided through the opening in the web 16 of the load carrier 14 through to a supply cable 36 and plugged into this, which belongs to the beam profile 18 on the right side of the right load carrier 14.

It is clear from the above description that a number of beam profiles 18 with luminaire modules 20 contained therein can be arranged between adjacent load carriers 12, 14, so that the luminaire modules 20 contained therein can be connected in series to the mains connection 32.

The beam profiles 18 can be easily flanged to the webs 16, the load carrier 12,14 otherwise. By contrast, the lighting modules 20 are inserted into the recesses of the beam profiles 18 and secured therein by clips, as will be described in more detail below. Since the electrical connection of the lamp modules 20 can be done without tools, a very simple installation is possible. For this purpose, no specialist such as an electrician needs to be consulted.

The attachment of a single luminaire module 20 in a beam profile 18 is only to be understood as an example. Naturally, in the context of the present invention, a plurality of luminaire modules 20 along the length of the beam profile 18 may be arranged in corresponding recesses and connected to each other at their supply cables 28, so that they are connected in series within the beam profile 18 and at the profile ends to a network connection 32 and . Are connected to another identical beam profile 18. In the following, for the sake of simplicity, however, reference will further be made to a beam profile 18 which contains a single luminaire module 20, as in the above-described Fig. 1 ,

The detailed design of the beam profile 18 and the luminaire module 20 inserted therein will be explained in more detail by way of example with reference to the following figures.

Fig. 2 shows the beam profile 18 in a shortened form opposite Fig. 1 , It is understood that the length of the beam profile 18 is adapted to the local conditions, in particular to the distance of the load carrier 12,14. As in the cross section in Fig. 3 is visible, the beam profile 18 is made as an upwardly open hollow profile of a sheet metal blank. Since the inventive function of the present luminaire mounting system is not bound to the fact that the beam profile 18 is horizontal, the open side should be referred to below neutral as the back 38, while the side 22 with the recess forms a front on which the bulbs are exposed. In the ceiling construction in Fig. 1 So is the front 22 below and the back 38 above. However, the beam profile 18 can also be installed so that its longitudinal axis is vertical and emit the bulbs laterally.

The beam profile 18 comprises at its front side 22 a flat bottom 40 in which the rectangular recess is mounted, and two vertical side walls 42, 44 which extend from the edges of the bottom 40 to the back 38. At their rear edges, the side walls 42,44 are drawn inwardly, so that inwardly extending flanges 46 are formed, which limit the opening 48 on the back 38 of the beam profile 18 on both sides. This cross section of the beam profile 18 remains the same over its entire length.

Between the parallel side walls 42,44 is the lamp module 20 a. The housing 22 of the lamp module 20 has a circumferential step 50, which serves as a stop when inserting the lamp module 20 in the recess. The gradation 50 is then on the edge of the recess. Except for the transparent cover 52, the lamp module 20 is thus recorded in the beam profile 18 and largely hidden to the viewer, as well as the supply cable (in Fig. 2 to 4 not shown in detail), which are performed in the beam profile 18.

Furthermore, it is not important for the function of the luminaire mounting system according to the invention to the exact shape and shape of the lamp module 20. In particular, the in the Fig. 2 and 3 illustrated housing form to be understood merely by way of example, and the circumferential step 50 can also be replaced by other stops, which are selectively attached to the housing circumference. In the present case, the luminaire module should contain LED lights. However, it is also conceivable a luminaire module containing a conventional fluorescent tube as a light source.

Fig. 5 again shows the beam profile 18 in a perspective view, without the lamp module 20 and in a opposite Fig. 1 shortened form. Clearly visible are the inwardly drawn edges 46 at the upper edges of the side walls 42,44.

Between these walls 42,44 is according to Fig. 6 a clip 60 can be used which serves to press the lamp module 20 from the open rear side 38 into the recess of the beam profile 18. The clip 60 comprises a central web 62, which runs parallel to the bottom 40 of the beam profile 18. At both ends of this central web 62, legs 64, 66 adjoin, which diverge somewhat from the middle web 62 and thus are at an angle to one another (see detailed view of the clip 60 in FIG Fig. 7 ). These legs 64,66 can be resiliently compress and have on their outer sides notches 68. Further, the legs 64,66 go over at a level below the central web 62 in projections 70 which extend from the central web 62 down in the direction of the bottom 40 of the beam profile 18.

The clip 60 can be pushed into the open back 38 in such a manner that the outsides of the legs 64, 66 of the clip 60 slide between the inwardly drawn edges 46 of the open back 38 until the latches 68 pass the edges 46 and against them engage. That is, the detents 68 resiliently slide under the flanges forming the inwardly drawn edges 46. This position is in Fig. 6 shown. From this mounting position, the clip 60 can only be removed by the legs 64,66 are resiliently compressed by hand.

In the mounting position in Fig. 6 the clip 60 exerts a downward pressure on the top of the light module 20 so that it is securely held in the recess and can not move or loosen. The insertion of the lamp module 20 and the attachment of the clip 60 can be done without the use of a tool. This also applies to the removal of the clip 60 and the lamp module 20. The clip 60 thus provides a particularly simple form of the holder for the lamp module 20th

The clip 60 is preferably made of an elastically deformable plastic, but can also be replaced by a metal clip. Fig. 8 shows a cross section through the beam profile 18 accordingly Fig. 3 with inserted clip 60.
