Description

The invention relates to a system for realizing a modular ceiling light according to the preamble of claim 1 and a method for realizing a ceiling light by means of such a system.

In the prior art, ceiling lights are often used to illuminate rooms, in particular for interior lighting, in particular to illuminate offices, meeting rooms and corridors. Such ceiling lights should, on the one hand, bring about the most pleasant possible visual appearance for the viewer and, on the other hand, ensure the most pleasant possible lighting of a room. In the prior art, both ceiling lights are known that only ensure direct irradiation, ie when they are mounted on a ceiling, light emission away from the ceiling, and ceiling lights that simultaneously ensure direct and indirect lighting, ie lighting on the one hand from the ceiling away and on the other hand towards the ceiling. Direct lighting is particularly advantageous for workplace lighting, and indirect lighting for background lighting of a room. Generic ceiling lights are usually attached to a ceiling in such a way that their vertical upper side points towards the ceiling and extends flatly along the horizontal. Usually the ceiling lights show this a flat, horizontal light exit window through which they emit light. The light exit window provided on its vertical underside usually takes up at least 70%, in particular between 70% and 95%, of the horizontal extent of the ceiling light. Generic lights are mostly elongated, their longitudinal extent being at least three times their transverse extent and at least ten times their vertical extent. Depending on the size and furnishing of a room, it is necessary to provide ceiling lights with different horizontal extensions of their light exit windows. In the prior art, this is ensured by providing a different number of the same ceiling lights with the same light exit window in the room, depending on the size and furnishing of a room, or that a suitable lamp is selected from a large number of lamps depending on the size and furnishing of a room , which then has a light exit window with a corresponding horizontal extension. However, this approach has various disadvantages. On the one hand, when different, separate ceiling lights are provided, an individual power supply and an individual mounting of the ceiling light on the ceiling are required. On the other hand, the availability of a large number of different ceiling lights with different light emission windows causes high manufacturing costs, high storage costs and complex assembly because of the large number of different ceiling lights to be provided, since depending on the ceiling light there is a specific installation of the respective ceiling light on the ceiling has taken place. In WO 2011/028773 A1 is a system for realizing a modular ceiling light disclosed in which longitudinal profiles are provided which are connected to each other by cross connectors. In a first assembly arrangement, two longitudinal profiles are arranged side by side and connected to one another by transverse connectors designed as end pieces, whereby a first ceiling light is realized. In a second assembly arrangement, two lamp modules are provided, each having two longitudinal profiles, which are connected to one another at one longitudinal end via a transverse connector designed as an end piece and are connected to one another at their other longitudinal ends via a connecting module. Also in DE 101 39336 A1 a system for realizing a modular ceiling light is disclosed.

The invention is based on the object of providing a system for realizing a modular ceiling light, with which the described disadvantages existing in the prior art can be at least partially eliminated. A further object of the invention is to provide a method for realizing a ceiling light by means of a system according to the invention, with which the disadvantages described in the prior art can be at least partially eliminated.
As a solution to the described objects on which the invention is based, the invention proposes a system having the features of claim 1. The basic idea of the invention is to provide a system for realizing a modular ceiling light, the system having modular components, by combining them with one another by arranging the respective components in a specific mounting arrangement, different ceiling lights can be realized. According to the invention, the system comprises at least two lamp modules which are each delimited in a vertical direction by an upper side and a lower side. Each of the luminaire modules comprises at least two separate longitudinal profiles that are elongated in a longitudinal direction, as well as at least two separate transverse connectors. The longitudinal profiles are profile elements that can be made, for example, from plastic or a metal, in particular aluminum, for example by means of extrusion or extrusion processes. The cross connectors can also be made of metal or plastic, for example. The cross connectors are preferably made from sheet metal by means of cutting and forming processes. In each of the at least two lamp modules, its two longitudinal profiles are arranged at a distance from one another in a transverse direction which is perpendicular to the longitudinal direction and are connected to one another in the transverse direction via the at least two transverse connectors. Both the two longitudinal profiles and the two transverse connectors are thus in the production of a Luminaire module separate components that are suitably connected to one another for the production of the luminaire module, for example by screwing the two cross connectors to the two longitudinal profiles. Cross-connectors and longitudinal profiles are particularly preferably designed to correspond to one another in such a way that the two cross-connectors rest positively on both longitudinal profiles of the luminaire module and in particular are also attached to the longitudinal profiles by screwing, welding or riveting. In any case, the two longitudinal profiles and the two transverse connectors of a lighting module form a rigid basic structure of the respective lighting module.

Each of the at least two lamp modules also has at least one light source and at least one optical element. The light source is arranged in a receiving space enclosed in the transverse direction by the longitudinal profiles, and the optical element forms an underside section of the lamp module. Particularly preferably, the receiving space is delimited in the transverse direction by the longitudinal profiles and in the longitudinal direction by the transverse connector. The light source is particularly preferably arranged on one side of one of the two longitudinal profiles which points in the transverse direction to the other of the two longitudinal profiles of the light module. The at least one light source, that is to say all the light sources of a lamp module, are arranged exclusively within the vertical extent of the longitudinal profiles is particularly preferred. In one embodiment, each of the at least two luminaire modules has two optical elements which are vertically spaced from one another, a first of the optical elements forming a lower side section of the luminaire module and a second of the optical elements forming an upper side section of the luminaire module.

Particularly preferably, the at least one optical element is plate-shaped and held on the two longitudinal profiles and extends in the transverse direction continuously between the two longitudinal profiles and delimits the receiving space in which the light source is arranged at its lower end. Correspondingly, this can also apply to the second optical element, which preferably forms an upper side section of the lamp module and can also be designed as a plate-shaped element that delimits the receiving space at its upper end.

According to the invention, each lamp module has a fastening device for an end piece at each of its two longitudinal ends, the system comprising at least two end pieces. Each of the end pieces has a fastening device that corresponds to one of the fastening devices of each lamp module for fastening the end piece to one of the longitudinal ends of one of the lamp modules. In a first assembly arrangement in which a first ceiling light is implemented, one of the end pieces is attached to each end of one of the light modules and forms a longitudinal end of the first ceiling light. This first ceiling light includes only one of the system's light modules. In one embodiment, each lamp module has a first fastening device for a first end piece at its first longitudinal end and each lamp module has a second fastening device for a second end piece at its second longitudinal end. The fastening device of the first longitudinal end is designed to correspond to the fastening device of the first end piece, and the fastening device of the second longitudinal end is designed to correspond to the fastening device of the second end piece. Particularly preferably, each of the end pieces has such a fastening device which is designed to correspond to the two fastening devices that are provided on the two longitudinal ends of the lamp module. The fastening devices at the two longitudinal ends of each lamp module are particularly preferably designed identically. In the first mounting arrangement, the end pieces form the longitudinal ends of the first ceiling light and also form an underside section of the first ceiling light. This underside section formed by the two end pieces in the first assembly arrangement preferably directly adjoins the underside section formed by the optical element. In the first assembly arrangement, the optical element is particularly preferably arranged above the lower ends of the two longitudinal profiles and the two end pieces.

According to the invention, the system comprises at least one connection module for connecting two of the lamp modules, the connection module having fastening units corresponding to the fastening devices at its two longitudinal ends for fastening the connection module to the facing longitudinal ends of the two lamp modules in a second Mounting arrangement in which a second ceiling light is implemented and in which the two light modules are arranged side by side in the longitudinal direction and are fixed to one another by the connection module. In the second assembly arrangement in which the second ceiling light is implemented, one of the end pieces is particularly preferably attached to a longitudinal end of each light module facing away from the other light module. The connection module is thus arranged in the second mounting arrangement with reference to the longitudinal direction at least in sections between the two lamp modules arranged next to one another and / or arranged overlapping with the two lamp modules in the longitudinal direction. The luminaire modules arranged next to one another are connected to one another by the connection module and fixed to one another. In one embodiment, the connection module has a fastening device at a first of its longitudinal ends, which is designed to correspond to a fastening unit that has one of the two lamp modules at its first longitudinal end, and the connection module has a fastening device at its second longitudinal end which corresponds to a fastening unit is formed which has the second of the lamp modules at its second longitudinal end, the second lamp module pointing with its second longitudinal end to the first lamp module and the first lamp module pointing with its first longitudinal end to the second lamp module, so that the first longitudinal end of the first lamp module to the second longitudinal end of the second lamp module. A first of the end pieces has a first fastening device that is designed to correspond to the fastening device that is provided at the second longitudinal end of the first lamp module, and a second of the end pieces has a fastening device that is designed to correspond to the fastening device that is provided on the first longitudinal end of the second lamp module is provided. In a particularly preferred embodiment, the connection module has a fastening device at each of its two longitudinal ends, which is designed to correspond to the two fastening devices of each lamp module that are provided at the respective longitudinal ends of the lamp module. Particularly preferably, the connection module has fastening units of identical design at its two longitudinal ends.

The system according to the invention has significant advantages compared to conventional systems for realizing ceiling lights. Because the system according to the invention makes it possible, by using a relatively small number of different system components, to realize a large number of different ceiling lights, which are located in the horizontal extent of their light exit window, which in the present case is preferably through the optical element and thus through the horizontal extent of the optical element is trained, differentiate. The provision of luminaire modules, end pieces and connection modules designed as explained ensures that, on the one hand, a luminaire can be realized with only one luminaire module, which can be designed in a visually appealing manner thanks to the end pieces provided on the longitudinal ends of the luminaire module, and at the same time the realization of a very elongated ceiling light made possible in that two adjacent light modules are connected to each other via a connection module and one of the end pieces is attached to the longitudinal ends of the outermost light modules pointing away from each other. In general, the system according to the invention preferably has a number of different end pieces, each of which has an identical or similar fastening device, but which differ in the functional elements that they comprise. In one embodiment, this includes System a group of end pieces, each of which has a fastening device, which are designed to correspond to the same fastening device of a certain light module of the system, each of the end pieces having its own functional element and the end pieces differing in their functional elements. For example, a certain end piece of the group can be designed without a functional element and / or another end piece of the group can have a camera as a functional element and / or another end piece of the group can have an infrared or radar sensor as a functional element and / or another end piece of the group can have a WLAN Module, for example a WLAN repeater as a functional element and / or another end piece of the group have a ZigBee module as a functional element and / or another end piece of the group have a Bluetooth module as a functional element and / or another end piece of the group Have smoke alarms as a functional element and / or have a further end piece of the group an operating device as a functional element. This can make it possible that, thanks to the modularity of the embodiment according to the invention, a user can subsequently change or add to the functional scope of his lamp, which he has implemented using the system according to the invention, by simply exchanging at least one end piece of the lamp. In the system according to the invention, the luminaire modules particularly preferably each have a vertical extension length that is less than 20%, in particular less than 10% of their extension length in the longitudinal direction and less than 30%, in particular less than 20% of their extension length in the transverse direction. The inventors have recognized that the system according to the invention is particularly advantageous for the implementation of such ceiling lights that are very flat, since the modular structure means that the components mentioned can also be provided, ie also when one is provided accordingly Flat installation space, thanks to the modular components of the system ceiling lights with different lengths and thus with different horizontal extension of their light exit windows, which are formed in particular by the underside section formed by the optical element, is made possible. The system according to the invention can, in particular in various embodiments, have features that are explained above in connection with generic systems. By means of the system according to the invention it is of course possible to realize a great number of different mounting arrangements for realizing different ceiling lights, the system according to the invention in any case being suitable for realizing the specified mounting arrangements.

According to the invention, each of the at least two lamp modules has two electrical plug-in devices which are each held on a longitudinal end section of one of its longitudinal profiles and are each accessible from one of the longitudinal ends. Particularly preferably, each lamp module has a first electrical plug-in device at its first longitudinal end, which is designed as a plug, and at its second longitudinal end opposite the first longitudinal end, a second electrical plug-in connection, which is designed as a socket. The longitudinal profiles of each lamp module are particularly preferably designed so that they form a cavity which extends in the longitudinal direction preferably over the entire length of the longitudinal profiles, with side wall sections with which they delimit the cavity, at least some of these side wall sections preferably on the outside of the lamp modules perpendicular to the longitudinal direction, in particular a section of the top and bottom and a section of a transverse side. Particularly preferably, receptacles for plug-in devices are arranged in the longitudinal profiles and fixed in the longitudinal profiles, the plug-in devices being held in the receptacles. For example, the receptacles can be made from plastic as injection molded parts. Locking connections are particularly preferably provided between the longitudinal profiles and the receptacles, via which the receptacles are fixed relative to the longitudinal profiles. The electrical plug-in devices and in particular the receptacles are particularly preferably arranged in the lamp modules in such a way that their flat extension perpendicular to the longitudinal direction extends exclusively in the area of the longitudinal profiles. In one embodiment, power cables are provided in each lamp module, with at least 90% of the length of the power cables, in particular 100% of the length, running in each lamp module within a horizontal extension of its longitudinal profiles, particularly preferably within the spatial extension of the longitudinal profiles. All electrical supply units, for example ballasts and / or plug connections and / or power cables, of each lighting module are particularly preferably arranged within the horizontal extent, in particular within the spatial extent of its longitudinal profiles. By providing plug-in devices and / or power cables and / or other electrical supply units, which are arranged exclusively or at least essentially within the spatial extent of the longitudinal profiles and / or are held on a longitudinal profile, it can be easily realized that the light module in Transverse direction between its longitudinal profiles has a light exit window, from which light can exit without the risk of shadow formation by electrical elements. By arranging plug-in devices on longitudinal end sections and at least one of the longitudinal profiles of each lamp module, which are each accessible from the longitudinal end, both a simple supply of the lamp modules and a simple electrical contacting of two adjacent lighting modules, which are connected to one another via a connection module, can be achieved.

In one embodiment, the lamp modules each have an identically designed fastening device at their two longitudinal ends. In one embodiment, each of the lamp modules has a pair of longitudinal profiles, the pairs of longitudinal profiles of the lamp modules being of identical design. The longitudinal profiles of each of the lighting modules, in particular the longitudinal profiles of all lighting modules, particularly preferably have an identical cross section. The longitudinal profiles of each lamp module, in particular the longitudinal profiles of all lamp modules, are particularly preferably designed to be identical. The lamp modules are particularly preferably designed identically. Due to the identical design of individual components of the lamp modules or the lamp modules themselves, the production of the lamp modules can be simplified even further, whereby the production costs can be reduced even further. In addition, the storage for the production of light modules and thus also for the production of ceiling lights of different lengths can be particularly simple. The cross connectors of the lamp modules are particularly preferably designed identically. By providing longitudinal profiles with an identical cross-section over their entire longitudinal extent, the production of the longitudinal profiles can be further simplified; for example, such a longitudinal profile can be produced in a simple manner in any length by means of an extrusion or extrusion process, with the longitudinal profiles of the light modules then starting can be produced from a profile element produced by extrusion or extrusion by cutting this profile element to length. The identical design of the cross connectors also enables a reduction in the Manufacturing costs, since a cross connector can then always be produced from a sheet metal using an identical sequence of work steps, which cross connector can then be used as a cross connector for each lamp module.

In one embodiment, at least some of the lamp modules comprise a second optical element which forms a top section of the respective lamp module to ensure indirect lighting. The light source is particularly preferably arranged in a receiving space which is delimited at its upper end by the second optical element and is delimited at its lower end by the first optical element, which forms the underside section of the respective light module. The optical element or the optical elements, if several of them are provided in a lamp module, are particularly preferably designed to be translucent, so that a direct view from the outside into the receiving space in which the light source is arranged is impeded. By providing two optical modules, the field of application of ceiling lights that can be implemented with the set according to the invention can be expanded even further.

In one embodiment, the connection module has a mounting element for fixing to an upper side of the two adjacent lamp modules and a web element that extends vertically downward away from the mounting element. Particularly preferably, the mounting element is designed as a mounting plate and the web element is designed as a web plate. By providing a mounting element that is fixed in the second mounting arrangement on the upper side of the two side-by-side lighting modules, two lighting modules can easily be connected in such a way that the mechanics of the connection by an observer after mounting the ceiling light on a ceiling can hardly you can see. Because usually a second Ceiling light, which is implemented by the second mounting arrangement, mounted with its top facing the ceiling, so that the mounting element is then hardly visible to a viewer. The mounting element is particularly preferably fixed to a respective cross connector of the two lamp modules arranged next to one another. In general, the transverse connectors particularly preferably have a cross-section perpendicular to the transverse direction in the manner of an L over at least 50% of their extension length along the transverse direction, whereby their rigidity can be particularly increased. Particularly preferably, one leg of the L is the top of the cross connector in the lamp module, and thus also in the second mounting arrangement, and the second leg of the L is arranged to run vertically and faces the closest longitudinal end of the lamp module. In this embodiment, the mounting element can particularly preferably be attached to this leg of the L which forms the upper side of the cross connector. Particularly preferably, the mounting element has at least one, in particular two, recesses spaced apart from one another in the transverse direction, the system comprising a fastening element to which a fastening cable for fastening the ceiling light to the ceiling is fastened. The mounting element preferably has a guide for one of the fastening elements on its underside below the recess. Correspondingly, the fastening element can be attached to the underside of the mounting plate and the fastening cable can extend upward through the recess, which enables the ceiling light to be easily and stably mounted on a ceiling. The web element particularly preferably has at least one, in particular two, recesses, each of the recesses in the second mounting arrangement being aligned with one of the recesses provided in the mounting element, the recess of the web element corresponding to the fastening element is designed that the fastener can be received in it. Particularly preferably, the web element restricts the movement of the fastening element vertically downward in the second mounting arrangement. In general, through the interaction of the mounting element and the web element, the fastening element can be held securely in relation to the second ceiling light, which can particularly simplify the fastening of the second ceiling light to a ceiling via fastening cables. The web element can, for example, form a support area for the optical elements of the two light modules arranged next to one another. In one embodiment, the two luminaire modules in the second assembly arrangement are in continuous contact with one another at their longitudinal ends facing each other with their longitudinal profiles, at least in sections, in particular at least on the sides of their longitudinal ends forming an underside section of the second assembly arrangement, in particular the optical elements of the two adjacent luminaire modules in the longitudinal direction are spaced from one another by a gap. The gap preferably has a longitudinal extent of less than 5 mm, in particular less than 1 mm, in particular a longitudinal extent between 0.5 mm and 5 mm, in particular between 0.5 mm and 3 mm, in particular between 1 mm and 5 mm. Particularly preferably, the web element is arranged in the longitudinal direction at the level of the gap and is arranged offset upward in the vertical direction from the first optical elements of the lamp modules, which each form an underside section of the respective lamp module. Correspondingly, the lower side of the web element points towards the gap between the first two optical elements of the two adjacent lamp modules. Since the lamp modules and the connection module are designed to correspond to one another in such a way that in the second assembly arrangement the longitudinal ends of the two lamp modules with their longitudinal profiles bear against one another at least in sections, a stepless transition between the two light modules arranged next to each other can be realized in the second ceiling light. By providing a gap between the two optical elements of the two lamp modules, a difference which exists between the heat-dependent length expansion of the longitudinal profiles and the heat-dependent length expansion of the optical elements can be taken into account. It must be taken into account here that the optical elements are typically made from a different material than the longitudinal profiles. For example, the longitudinal profiles are subject to high rigidity requirements, whereas the optical element must meet lower rigidity requirements, but must have certain optical properties for this. Providing a play between the optical elements of the two adjacent lamp modules ensures that no mechanical tensioning occurs between the two optical elements of the two adjacent lamp modules if the optical elements expand excessively relative to the longitudinal profiles of the lamp modules. The arrangement of the bar element in the longitudinal direction at the level of the gap can also ensure that the gap between the optical elements is barely perceived by an observer. On the one hand, the web element then prevents a viewer from looking directly through the gap into the interior of the second ceiling light. On the other hand, the staggered arrangement of the bar element relative to the top of the optical elements ensures that light reaches the underside of the bar element from the receiving space and is reflected and radiated downwards, making the gap even less perceptible to an observer from outside becomes.

In one embodiment, the system has an intermediate module for connecting the two lamp modules, wherein the Intermediate module has fastening units corresponding to the fastening devices of the lamp modules at its two longitudinal ends for fastening the intermediate module to the facing longitudinal ends of the two lamp modules in a third assembly arrangement in which a third ceiling lamp is implemented and in which the intermediate module is arranged in the longitudinal direction on the two lamp modules and the two lamp modules are fixed to each other. As already explained for the connection module, the intermediate module can also be designed in such a way that it has identically designed fastening units at its two longitudinal ends or, alternatively, can be designed such that it has a first fastening unit at a first longitudinal end and a second fastening unit at a second longitudinal end, with the first fastening unit is designed to correspond to a fastening device which is provided at a first longitudinal end of a first lamp module, and the second fastening unit is designed to correspond to a second fastening device which is constructed at a second longitudinal end of a second lamp module, the first longitudinal end of the first Luminaire module points to the second longitudinal end of the second luminaire module and these two longitudinal ends of the two luminaire modules are connected to one another by the intermediate module. In the third assembly arrangement, one of the end pieces is particularly preferably fastened to a respective longitudinal end of each of the two lamp modules which faces away from the other lamp module and which are fixed to one another by the intermediate module. Of course, other assembly arrangements are also conceivable in which the third assembly arrangement is present and, in addition, a further lamp module is attached to at least one of the longitudinal ends of one of the two lamp modules, which faces away from the other lamp module, via a connection module or a further intermediate module, wherein one of the end pieces is then arranged and fastened to the two longitudinal ends of the two outermost lamp modules, which face away from one another, as explained above. The intermediate module has a module body. The module body preferably has two separate module longitudinal profiles running in the longitudinal direction and two module transverse connectors, via which the module longitudinal profiles are connected to one another. In the third assembly arrangement, the module longitudinal profiles are particularly preferably in contact at their longitudinal ends, at least in sections, on one longitudinal end of one of the longitudinal profiles of the lamp modules which are connected to one another by the intermediate module. By providing an intermediate module that differs from the connection module and has a module body, the set according to the invention enables an even greater number of ceiling lights to be implemented, each of which has different functions. In the third mounting arrangement, the longitudinal ends of the lamp modules facing each other, which are connected to one another by the intermediate module, are particularly preferably spaced apart from one another at least over the length of the module body, this length of the module body preferably being at least 5 cm, in particular at least 10 cm. The module body particularly preferably extends over the same length in the transverse direction as the two lamp modules. Particularly preferably, the module body extends at its longitudinal ends over the same cross-sectional extent perpendicular to the longitudinal direction as the two lamp modules at their respective longitudinal ends facing the module body. The intermediate module particularly preferably has a functional element. For example, a sensor or a camera can be provided as the functional element. The module body particularly preferably has a non-transparent plate element which forms at least 50% of its underside section, with a recess preferably in the plate element is provided, to which a functional element is arranged in alignment. The functional element preferably dips through the recess, at least in sections. Correspondingly, such a modular ceiling light in which such an intermediate module is provided, for example, have a motion sensor for detecting a movement for switching the light on and off or a camera, for example for detecting objects, differentiating objects or counting objects. Particularly preferably, the module longitudinal profiles have the same cross section as the longitudinal profiles of the lamp modules. Particularly preferably, the module cross connectors are designed identically to the cross connectors of the lamp modules. In one embodiment, the system comprises a group of intermediate modules, each of which has a fastening unit that is designed to correspond to the same fastening device of a specific lamp module of the system, each of the intermediate modules having its own functional element and the intermediate modules of the group differing in their functional elements. For example, a certain intermediate module of the group can have a camera as a functional element and / or another intermediate module of the group can have an infrared or radar sensor as a functional element and / or another intermediate module of the group can have a WLAN module, for example a WLAN repeater, as a functional element and / or have another intermediate module of the group ZigBee module as a functional element and / or another intermediate module of the group have a Bluetooth module as a functional element and / or another intermediate module of the group have a smoke detector as a functional element and / or another intermediate module of the group Have operating device as a functional element, one of the intermediate modules of the group preferably not having a functional element. This can enable that thanks to the modularity of the Embodiment according to the invention, a user can set the functional scope of his lamp by providing, in particular the subsequent exchange of at least one intermediate module of the lamp.

In terms of the modular structure of the system according to the invention, further simplification can be made possible in this embodiment. Because the module body can thus be attached to a light module using connection modules, which are also used to connect two light modules to each other, so that a high variability of the design of ceiling lights is achieved by using a small number of different components the system according to the invention can be implemented. In one embodiment, the module body has a fastening device corresponding to the fastening device of at least one of the end pieces at at least one of its longitudinal ends, with the module body fastened at a longitudinal end to a first of the end pieces in a fourth assembly arrangement in which a fourth ceiling light is implemented is and is attached at its other longitudinal end to one of the lamp modules, the module body being particularly preferably fastened to this lamp module by means of a connection module. The module body particularly preferably has one at each of its two longitudinal ends Fastening device which are designed to correspond to both the fastening units of the connection module and the fastening device of at least one of the end pieces, in particular the fastening devices of all end pieces of the system.

In Figure 1 comprehensive the Figures 1a, 1b , 1c, 1d and 1e are various views of sections of a lamp module 1 of a system according to the invention or of some of its in various schematic principle representations Elements, shown. From the synopsis of Figures 1a, 1b , 1c and 1d the basic structure of each lamp module 1 of the described embodiment of a system according to the invention can be seen. Such a lamp module 1 has two longitudinal profiles 10 which are elongated in a longitudinal direction X and which are connected to one another by two transverse connectors 11 running in a transverse direction Y. The design of the longitudinal profiles 10 and the transverse connector 11 is in particular from the Figures 1c and 1d recognizable. The longitudinal profiles 10 each have an identical cross section perpendicular to the longitudinal direction X and in the present case are produced from aluminum by means of an extrusion process. The cross connectors 11 are made from sheet metal by means of cutting and forming processes. The cross connectors 11 are each designed identically. The longitudinal profiles 10 each form a cavity 100 which extends in the longitudinal direction X over the entire length of the longitudinal profiles 10. A longitudinal guide, as explained above, accessible from each longitudinal end, is formed in the cavity. As from the synopsis of the Figures 1a, 1b and 1c the longitudinal profiles 10 can be seen to have side wall sections with which they delimit the cavity 100, these side wall sections forming the outer sides of the lamp modules 1 perpendicular to the longitudinal direction X. In the present embodiment, the cavity 100 is completely enclosed circumferentially running around the longitudinal direction X, with a further side wall being provided which does not form an outside of the light module 1 but faces the longitudinal profile 10 opposite in the transverse direction Y. The longitudinal profiles 10 also have a guide 101, which in the present case is designed as a groove which has an undercut on its upper side, wherein a fastening element to which a rope is fastened can be reliably held in the guide 101. How out Figure 1c This guide 101, designed as a groove with an undercut, can be seen in an end section of the longitudinal profile 10 interrupted, whereby an insertion area is formed through which the fastening element, which can be designed for example in the manner of a ball or a cylinder with a round base, can be inserted when the longitudinal profile 10, as in the Figures 1a and 1b can be seen, is connected to another longitudinal profile 10 via cross connectors 11 and is integrated into a lamp module 1. The cross connectors 10 each have a cross section perpendicular to the transverse direction Y in the manner of an L. The cross connectors 11 each have this cross section over more than 70% of their length in the transverse direction Y. The cross connectors 11 each have a clamping device 110 for a PE contact. The housing of the lamp module 1, which is essentially formed by the longitudinal profiles 10 and the transverse connectors 11, can be connected in a simple manner to a protective conductor via this, which is generally advantageous according to the invention. In the present embodiment, the cross connectors 11 are formed from a metal sheet. In Figure 1e a section of a lamp module 1 is shown with a view of its first longitudinal end, in the illustration for the sake of simplicity only the first optical element 12 forming a bottom section of the lamp module 1 is shown, but not the second optical element 15 forming a top section of the lamp module 1, which however, for example in the Figures 3b , 4b and 4d is shown. In the described embodiment according to the invention, all lamp modules 1 are designed to provide direct and indirect lighting. The direct illumination takes place by emitting light through a light exit window which is formed by the first optical element 12, the indirect lighting takes place by light emission through a light exit window which is formed by the second optical element 15. How out Figure 1e To see, the lamp module 1 has a receiving space, which in the transverse direction Y through the two The longitudinal profiles 10 and is limited in the longitudinal direction X by the two transverse connectors 11. Two light sources 13 are arranged in this receiving space, of which in FIG Figure 1e only one is shown. The light sources 13 are each designed as an LED chain elongated in the longitudinal direction X, each of the light sources 13 being arranged on one side of one of the longitudinal profiles 10 which delimits the receiving space and which faces the other longitudinal profile 10, which is generally advantageous according to the invention. A person skilled in the art can see that with a very low overall height along the vertical direction Z, a high light emission intensity can be provided by the lamp modules 1 and that, because of the arrangement of the LEDs on the named sides of the longitudinal profiles 10, a good light mixing can take place in the receiving space and thus homogeneous light emission via the optical elements 12, 15 can be guaranteed. Out Figure 1e It can also be seen that an electrical plug-in device 14 is provided at the first longitudinal end of the lamp module 1, which is held within the cavity 100 of one of the longitudinal profiles 10 on a longitudinal end section of the longitudinal profile 10 and from the longitudinal end of the longitudinal profile 10 and thus from the first longitudinal end of the lamp module 1 is accessible. This plug-in device 14 enables very simple contacting of the lamp module 1.

In Figure 2 an end piece 3 of the described embodiment of a system according to the invention is shown in a schematic diagram. Out Figure 2 It can be seen that the end piece 3 on the one hand has a plug element 31 which is designed to correspond to the plug-in device 14, and that on the other hand the end piece 3 has a fastening device which in the present case comprises side guides 30 and holes. This fastening device corresponds to the fastening device at the first longitudinal end of the Light module 1 formed, which is in Figure 1e is shown. This fastening device of the lamp module 1 comprises, on the one hand, longitudinal guides which are provided in the cavity 100 of the longitudinal profiles 10, and, on the other hand, holes which are provided in the transverse connector 11. To implement a first ceiling light, ie a first assembly arrangement of the components of the system according to the invention, the end piece 3 can according to FIG Figure 2 be introduced with its side guides 30 into the longitudinal guides of the longitudinal profiles 10 of the lamp module 1 in the longitudinal direction X until it reaches its end position in which the plug element 31 is in electrical contact with the plug device 14. In this end position, the end piece 3 can be fastened to the lamp module 1 by means of screws, since in this end position the holes provided in the end piece 3 are aligned with the holes provided in the cross connector 11. Out Figure 2 it can also be seen that the end piece 3 has a bushing 32 for an electrical power cable. Through this bushing 32, an electrical power cable can be introduced from the outside into the end piece 3 and thus into a ceiling light realized by means of the system according to the invention and connected within the end piece 3 to the plug element 31 of the end piece 3 for the electrical supply of a manufactured with the system according to the invention Ceiling lamp.

In Figure 3 comprehensive the Figures 3a and 3b a first ceiling light, which is realized by arranging components of the system according to the invention in a first mounting arrangement, is shown schematically in different views. From the Figures 3a and 3b it can be seen that in the first assembly arrangement, an end piece 2, 3 is fastened to each longitudinal end of the lamp module 1. In the present case, the end piece 3 is as in FIG Figure 2 shown and thus functions as a feed end piece. The End piece 2 is designed as a sensor end piece and shows how Figure 3a can be seen, a sensor, which in the present case is designed as a motion sensor for switching the lamp on and off. In Figure 3a the underside of the first ceiling light is shown in Figure 3b the top of the first ceiling light. From the Figures 3a and 3b it can be seen that the first optical element 12 forms more than 60% of the lower side section of the lighting module 1 and the first ceiling light, and that the second optical element 15 forms more than 60% of the upper side section of the lighting module 1 and the upper side section of the first ceiling light, which is according to the invention is generally beneficial. It can also be seen that the longitudinal profiles 10 and the end pieces 3, but not the transverse connectors 11, each form a top and a bottom section of the first ceiling light. This is generally advantageous according to the invention. The end pieces 2, 3 each form an absolute end of the first ceiling light in the longitudinal direction X.

In Figure 4 comprehensive the Figures 4a, 4b , 4c and 4d a section of a second ceiling light produced by the described embodiment according to the invention is shown. In the case of this second ceiling light, the components of the system according to the invention are in the second assembly arrangement. In this second assembly arrangement, two lamp modules 1 are in the present case arranged next to one another in the longitudinal direction X, with their longitudinal profiles 10 resting against one another at their longitudinal ends facing one another. In contrast, the first optical elements 12 of the two adjacent lighting modules 1 are spaced apart from one another in the longitudinal direction X by a gap 1000. In the present case, the gap has a longitudinal extent of 3 mm, with reference to its longitudinal extent, which it has over its entire extent along the transverse direction, of course. General can be in others Embodiments of the gap also have an infinitesimally small longitudinal extent, but preferably a longitudinal extent of at least 0.8 mm. The two lamp modules 1 arranged next to one another are connected to one another via a connection module 4. The connection module 4 is in Figure 5 comprehensive the Figures 5a, 5b and 5c shown in more detail in various views in which various of its components can be recognized. Out Figure 4a and Figure 4b it can already be seen that the connection of the lamp modules 1 by means of the connection module 4 provides an optically harmonious underside of the second ceiling lamp that is practically uninterrupted between the lamp modules 1, whereas only on the top of the second ceiling lamp, which is naturally hardly visible to an observer, the transition between the adjacent lamp modules 1 can be clearly seen because of the clearly visible connection module 4. In the present case, the connection module 4 has a mounting plate 41 and a mounting web 42. The mounting plate 41 has an element of the fastening units of the connecting module 4, which correspond to the fastening devices of the longitudinal profiles 10 and which are arranged in the second mounting arrangement in alignment with the holes of the fastening devices which are provided in the cross connectors 11 of the lamp modules 1, as shown in FIG Figure 1 is recognizable. Correspondingly, the mounting plate 41 can easily be screwed tightly to the facing longitudinal ends of the two lamp modules 1 using screws. The mounting web 42 is arranged on the underside of the mounting plate 41 and is screwed to it by means of screws 43. The mounting plate 41 also has recesses and guides 410, with one guide 410 being provided below the recess on the underside of the mounting plate. This guide 410 is designed as a ball guide and is used for receiving a fastener 44 as shown in FIG Figure 5b is shown. For this purpose, the mounting web 42 has a recess in which the fastening element 44 as in FIG Figure 5b shown can be arranged, wherein when the mounting plate 41 is screwed relative to the mounting web 42, the fastening element 44 is held captively in the connection module 4. In the described embodiment according to the invention, a fastening cable (not shown in the figures) is fixed to the fastening element 44, which exits the mounting plate 41 through the recess provided on the top of the mounting plate 41 and for fastening the second Ceiling lamp can be used on a ceiling. How out Figure 5c As can be seen, the connection module 4 also has a plug element 46 and stabilizing elements 45. The stabilizing elements 45 form part of the fastening unit of the connection module 4. The expansion of the stabilizing elements 45 corresponds to that with reference to FIG Figure 1 The longitudinal guides explained above, which are formed by the longitudinal profiles 10 at each longitudinal end of the lamp module 1, are formed. Correspondingly, for stable fixing of the two adjacent lamp modules 1 to one another, each of the stabilizing elements 45 can be introduced into a respective longitudinal guide formed by one of the longitudinal profiles 10, after which the longitudinal profile 10 of the other lamp module 1 can be pushed onto the two stabilizing elements 45 accordingly and then the mounting plate 411 can be fixed to the cross-connections 11 of the two adjacent lamp modules 1 using screws 43.

The functioning of the connection module 4 is in particular from Figure 6 comprehensive the Figures 6a and 6b evident. When implementing the second mounting arrangement, first the plug element 46 is plugged into a plug-in device 14 which is provided at a first longitudinal end of a first lamp module 1, and the stabilizing elements 45 are also inserted in the longitudinal direction X into the longitudinal guides at the first longitudinal end of the first lamp module 1. Then the second lamp module 1 is pushed with its second longitudinal end, which points to the first longitudinal end of the first lamp module 1, in the longitudinal direction X up to the stop against the first lamp module 1, during which the plug element 46 with its still free side into a plug-in device 14 engages, which is provided at the second longitudinal end of the second lamp module 1, and wherein the stabilizing elements 45 in the longitudinal guides, which are provided at the second longitudinal end of the second lamp module 1, are introduced. How out Figure 6a it can be seen that the two adjacent lighting modules 1 then abut one another with their longitudinal profiles 10, whereas their transverse connectors 11 are spaced apart from one another in the longitudinal direction X. Then the connection module 4 is arranged to connect the two adjacent lamp modules 1 to these lamp modules 1 by inserting the web plate 42 in the longitudinal direction X between the cross connectors 11 of the two lamp modules 1 and the mounting plate 41 on the top of the cross connectors 11 of the two lamp modules 1 is placed and then screwed to these two cross connectors 11. As a result, the lamp modules 1 are reliably fixed to one another. In Figure 6b the arrangement of the web plate 42 in the second mounting arrangement relative to the first optical elements 12 of the two lamp modules 1 is shown. How out Figure 6b As can be seen, the web plate 42 is arranged in the longitudinal direction X at the level of the gap 1000 that exists between the first optical elements 12 of the two lamp modules 1 and offset in the vertical direction Z to these optical elements 12, namely above the optical elements 12 arranged. This ensures that when the second ceiling light is viewed from its underside, the gap 1000 is almost imperceptible and that, moreover, when the light sources of the light modules 1 are switched on, light can be reflected downwards from the underside of the web plate 42, whereby the gap 1000 can be made even less clearly recognizable.

In Figure 7 comprehensive the Figures 7a , 7b , 7c , 7d and 7e is an intermediate module 5 and sections of a third ceiling light, in which the components of the system according to the invention are in a third assembly arrangement, shown schematically in different views. In the Figures 7a and 7b the third mounting arrangement is shown in the area of the transition from two lamp modules 1 to the intermediate module 5 arranged between them, with FIG Figure 7a the bottom, in Figure 7b the top is shown. From the Figures 7c , 7d and 7e shows the mode of operation of the intermediate module 5 and the structure of the intermediate module 5. The intermediate module 5 has a module body, which in the present case comprises two module longitudinal profiles 50 and two module transverse connectors 55 which connect the two module longitudinal profiles 50 to one another in the transverse direction Y. The module body also has a non-transparent plate 51 with a recess in which a movement sensor 52 is arranged. The intermediate module 5 also has two connection modules 4, which are designed as explained above, but do not include a plug element. This is because the module body itself has a connector element 54, 56 at its two longitudinal ends, each of the connector elements 54, 56 being designed to correspond to a connector 14 provided at the first or second longitudinal end of each lamp module 1. The intermediate module 5 has at its two longitudinal ends each fastening units, which by the Connection modules 4 of the intermediate module 5 are formed in the third assembly arrangement, as in particular from the synopsis of Figures 7b, 7c , 7d and 7e can be seen, connect the module body with the two facing longitudinal ends of the two lamp modules 1. The arrangement of stabilizing elements 45, web plates 42 and mounting plates 41 of the connection modules 4 is carried out in exactly the same way as explained above for the second mounting arrangement. The intermediate module 5 also has a cover plate 53, which covers the transition between the module cross connectors 55 of the module body at the top in order to prevent dust from entering the module body, the cover plate 53 being easily removable for maintenance of the intermediate module 5.

In Figure 8 comprehensive the Figures 8a, 8b , 8c and 8d a fifth mounting arrangement is shown in which a fifth ceiling light is implemented by means of the system according to the invention. This fifth ceiling light has a ceiling attachment unit 7, which has a structure with a vertical height, which extends horizontally over a smaller area than each of the lamp modules 1. At a first longitudinal end of the structure, a first end piece 70 is arranged, the side guides 700 and has a plug element 701, analogous to the end piece 3 according to FIG Figure 2 . The structure has a receptacle 73 at its opposite longitudinal end. To implement the fifth assembly arrangement, the second longitudinal end of the lamp module 1, as shown in FIG Figure 8b can be seen, a second end piece 3 is attached, on the upper side of which an attachment element 36 is arranged, which is designed to correspond to the receptacle 73. The corresponding design of attachment element 36 and receptacle 73 is in particular from the Figures 8c and 8d evident. For the realization of the fifth ceiling light, some of which are shown in Figure 8a is shown, first the second End piece 3 attached to the second longitudinal end of the light module 1, after which the light module 1 with the second end piece 3 attached is then pushed onto the ceiling mounting unit 7 by a horizontal movement in the longitudinal direction X, with the receptacle 73 and the attachment element 36 engaging with each other during this pushing on and the fastening device, which in particular comprises the side guides 700, engages in the fastening device on the first longitudinal end of the lamp module 1, which in particular comprises the explained guide grooves. By moving the lamp module 1 relative to the ceiling attachment unit 7 along the longitudinal direction X until an end position is reached and by fixing this end position with screws 43, the fifth mounting arrangement is achieved. The vertical height of the structure is coordinated so that the ceiling attachment unit 7 can first be attached to a ceiling with its upper side and then the lamp module 1 with the second end piece 3 can be pushed onto the ceiling attachment unit 7 as explained. This results in a particularly simple mountability of the fifth ceiling light on a ceiling. How out Figure 8a evidently, in the embodiment described in the fifth assembly arrangement, the structure covers the second optical element 15 horizontally only in sections, so that a light exit strip 150 is formed at two opposite horizontal ends of the structure through the optical element 15, through which from the in the fifth mounting arrangement trained ceiling lamp light can be emitted upwards to provide indirect lighting.
