EP3234459B1 - Modular illumination device - Google Patents

Description

The invention relates to a modular illumination device according to claim 1.

State of the art

A generic lighting device is for example from the EP 2 650 607 known as "modular LED light". The luminaire disclosed in this publication comprises a luminaire housing which is designed at the same time as a cable guide and which receives an operating device for the light element designated as a "controller", which in turn can be fastened to the underside of the operating device. This known device thus feeds the line network current via an upper interface into the operating device, in which this line network current flows into a supply current is converted to the operation of the LEDs and then fed via a lower - second - interface in the light element for its operation. In this known device, therefore, the operating device is designed as an intermediate element which is arranged "sandwiched" between the conduit element, which also acts as a housing, and the light element.

Other generic devices are from the US 4 688 154 A as well as the US 2005/002182 A1 known. The EP 2 650 607 A1 represents further state of the art.

Disadvantages of the prior art

By this structure, however, inevitably always an operating device for each light element is required, which requires a relatively complex structure. In this respect, the adaptation to other lighting tasks is relatively complex and requires trained personnel.

task

Starting from a lighting device of the aforementioned type, the invention is therefore based on the object at least partially to avoid these disadvantages and to provide a generic modular lighting device, which has a much simpler structure and insofar easier customizable to realize a modular customization conditions customizable.

invention

This object is achieved by a modular lighting device according to the main claim.

In particular, in the case of a modular illumination device of the type mentioned at the outset, this is already achieved in that the first interface is designed as an integral interface to the line power supply and the supply current output of the operating device. The contact management of the first interface thus comprises at least separate connections for bringing in and carrying out the line voltage provided via the line network or the line current (in Central Europe, for example, 230 volts at 50 hertz) and separate supply and removal of the supply current converted by the operating device to supply the Light source (s) in or on the light element.

A central element of the invention is thus the line element with the at least one integral interface, which thus in the line element for the realization of the connection technology with the other lighting elements (one or more light elements, one or more operating devices or even multiple line elements, etc.) customized and as needed to the each lighting situation can be assembled and also expanded as needed, preferably by simply mating the individual elements together.

The integral interface according to the invention thus comprises at the same time means for feeding the mains voltage or line current into the line element, and means for taking out the supply current provided by the operating device, e.g. via a supply line.

Preferably, the line element is also designed to also realize the data / control signal supply and the data / control signal output of the operating device via the integral interface. The data / control line and the integral interface can be designed for data transmission between at least one LED module and a control module, such as a DALI control unit for detecting the brightness and control of the lighting device.

Preferably, the operating device but also the entire lighting device is SELV-compatible.

Through this integral interface, the modular and customized structure of a luminaire is promoted in a special way, because the customer only has to connect the line element with the required additional lighting elements (light element, operating device) and can also realize different lighting tasks by using other elements or components.

Preferably, the integral interface comprises at least a first part of a plug which is at least electrically connectable in the installed position with a complementary formed second plug part on the counter element, wherein the plug parts but also ensure the required separate contact management in each case.

According to the invention, the line element comprises at least one second interface, designed to supply the light element with supply current. Preferably, the integral interface according to the invention is arranged at a front end of the line element, so that this line element can be easily supplied and the power can be tapped off and connected to other, complementary designed line elements. The second interface for connecting the light element is preferably provided on a lower or an upper side of the line element, so that the various connections or interfaces can be operated and accessed without mutual interference for the attachment and removal of other lighting elements and supply lines.

According to the invention, the line element is also designed to realize the supply current and the data / control signal routing for the light element with the light source via the second interface, which in the context of this invention as Is called "light interface".

Particularly preferred is the formation of the line element with molded-in these interfaces, so if this is formed as an integral part in the manufacturing process of the preferably made of plastic pipe element or the line element housing in this, or injected or embedded.

As already explained above, the complementary design of the integral interfaces or other interfaces of the line element is particularly advantageous in order to enable a simple and customized assembly, preferably by simple plug-in mounting, in which the first component of a complementary interface element with the second component of the complementary interface element of Counter element is connected.

The integral interface of the line element may be formed in a preferred development as a connection interface, which is thus designed for connection to other line elements. By means of this embodiment, two or more of the line elements can be interconnected to form a modular lighting device for power and / or data supply, e.g. also a longer strip of light, which extends for example below a hall ceiling of a workshop over several meters.

To relieve the interfaces, in particular the integral interfaces are preferably provided at the interfaces for realizing and relieving the connection in installation position, additional mechanical connection means. In the particularly preferred embodiment, these additional mechanical connection means are designed so that the electrical connection is not realized until the mechanical connection is made, preferably by means of at least one latching connection.

In another refinement, the connection of the line elements to one another takes place via a third interface provided on the line element, which is designed to connect the individual line elements in installation position and thus provide the energy and data supply for a more complex illumination assembly or a complex illumination system, e.g. an aforementioned lighting system.

The interfaces of the line element and the entire modular lighting device are preferably protected, that is adapted to fulfill a required for the particular application protection class or protection to protect people against potential hazards when using under different environmental conditions. For wet rooms, this is done, for example, by sealing rings, which engage sealingly in the installed position in the installation position on the complementarily formed interface parts.

The receiving space within a hollow conduit member for electrical components can be increased and the compactness can thus be increased if, in the manufacture of the conduit member, the conduits are integrated into it, so that the conduits are thus an integral part of the conduit member. This can be done, for example, that the current-carrying lines are integrated by injection molding within the sides or walls of the conduit element. The preferred embodiment provides for the formation of the lines within the line element as a stamped grid, which is particularly flat and thus particularly well the walls of a box-shaped example Can integrate line element.

The preferred embodiment thus provides that the volume of the insulation corresponds to the volume of the line element minus the volume of the lines, so no additional insulation for the lines is provided.

A further enlargement of the construction space or preferably within the hollow conduit element for defining a receiving space of electrical components can be realized that the conduit element is additionally formed as a line carrier element, that this thus has such a longitudinal and / or transverse rigidity, that it provides the central or complete carrying function of the lighting device, so no further support elements for attachment to the ceiling and to realize the longitudinal and transverse stiffness are required. Preferably this can be done by incorporating support elements in the duct element, e.g. an integral metal carrier or a glass fiber reinforced plastic carrier, in particular a profile for having a high longitudinal stiffness, z. B. for the formation of light band systems, so e.g. an angle profile, corner profile or a double T-beam.

Finally, it is also within the scope of the invention that in particular the integral interface but also the other interfaces of the line element in addition to the electrical and / or electronic connection means also comprise mechanical connection means, in particular for relieving the interface elements in installation position, which preferably as engaging behind each other in installation position detent - Are formed or snap connection.

The inherent rigidity, ie the possibility also the whole To realize carrier function of the lamp, so the individual lamp modules in mounting position carrying together to connect, supports in a special way the modular design of lights. This can be done for example in an outdoor light arranged at the upper end of a mast, characterized in that the mast attachment is designed to receive the electronic ballast and comprises a connector for connection to the cable carrier module. The in the installed position substantially transversely to the axis of the mast extending conductor support module thus realizes the electrical supply of at least one light element attached thereto and carries this simultaneously. To improve stability, an additional support frame may be provided.

The line element thus provides a complete system with integrated wiring or routing that can be designed intrinsically rigid by its geometric design and / or choice of materials and preferably, so as to realize as a carrier module partially or completely the carrier function of the lamp.

Preferably, the conduit member is adapted to receive electrical and / or electronic components of the luminaire, e.g. by at least partially defining with its walls a receiving space.

In the preferred embodiment, the conduit member as an elongated, box-shaped housing with two longitudinally substantially parallel to each other extending longitudinal sides and two longitudinal sides interconnecting end faces, which may be significantly shorter than the longitudinal sides, connected to each other to the longitudinal sides of the receiving space which can also be closed on all sides in order to fulfill the possibly required degree of protection (IP standard).

As a particularly preferred, the box-shaped or cup-shaped design of the line element has been found. The line element can thus even be designed to receive the operating device.

The conductor tracks in the line element can be produced in various ways. In a simple and particularly cost-effective variant, these are embedded in the plastic, but can be metallized on or in the wall surface of the conduit element, in particular in the case of more complex and variably configurable structures. Also possible is the application of an electrically conductive circuit diagram in the form of conductor tracks. In any case, a complete circuit diagram including the plug contacts can be realized in the line module. Particularly useful is the production in a 2-component injection molding (2K process), so if two or more different plastics are injected simultaneously or at least without opening the injection mold in the injection mold.

The light element preferably comprises at least one conductive carrier element with a plurality of LEDs, arranged and adapted to the light situation or visual task to be implemented.

The figures show various embodiments of line elements according to the invention, which are designed as line modules for connection to other lighting elements for creating customized module lights.

In the present case, the light-generating light modules are designed as LED modules, which comprise LEDs as light sources, which are preferably arranged colinearly along a longitudinal axis or as an LED array.

FIG. 1 shows a perspective side view of a line module according to the invention 2. The line module 2 consists in its entirety of an elongated, box-shaped Plastic housing, formed by a top plate 2a, extending transversely down two mutually parallel longitudinal walls 2b, 2c, which define at the front ends by means of two likewise mutually parallel end walls 2d, 2e an integrally closed, box-like structure, in this case the underside is open and defines a recording room. The line module 2 has already by its geometric design on a high longitudinal stiffness, or in other words, the line module is like a trough with the opening directed downward. An alternative embodiment provides an underside closed embodiment as a holistically closed line module or a closed by a cover line module.

Like that in the FIG. 2 shown lateral perspective sectional view shows the line module is designed as an integrated plug-in system and includes a housing with integrally enclosed in the top plate 2a lines 2f - 2k as well as connectors 2m, 2n, 2p, injected in the present case in the plastic injection molding in the housing. The six lines 2f-2k provided in the present embodiment connect the integral interface 21 provided in the front end in accordance with IP66 and the connector 2m provided in the top for connection to an ECG module 10. In this respect, the entire interior of the module defined by the line module 2 stands Housing for receiving luminaire components available, whereby this has a filigree shape.

FIG. 3 with a view of the line module 2 from below, shows the arrangement of the connector 2n, 2p trained light interfaces for the attachment of light modules to the line module 2. Plug connector 2m for the ECG is so far formed through the line element 2.

The FIG. 4 shows a perspective view of a moisture-proof lamp according to the invention formed using a designed as a line carrier module 4 line element from below. The line carrier module 4 thus forms the longitudinal stiffness forming element of the lamp, with which this on a developer, so a ceiling or the like, can be fastened, for. Example by means of brackets 6, 8, which span the top of the line carrier module 4 on the upper side and laterally border with their flexible side legs. An ECG module 10 is arranged on top of the cable carrier module 4 and coupled mechanically and electrically or electronically to the latter via the plug connector, which has a housing which is also box-like, but of smaller dimensions than the cable carrier module 4 and is designed to accommodate an electronic ballast , which controls longitudinally arranged light modules 12, 14 via the intermediate conductor carrier module 4 on the underside of the conductor carrier module 4. These light modules 12, 14 are connected via latching tabs releasably connected to the line carrier module 4 and are connected via complementary formed light interfaces electrically or electronically connected to the connectors 2n ,, 2p at the bottom of the line carrier module 4.

Alternatively, the conductor carrier module 4 may also be designed to accommodate the ECG module 10, e.g. in that the ECG module 10 can be inserted from above into the housing-type conductor carrier module 4 and can be connected to it via at least one connection or plug. In this case, interface 2m is arranged inside the line module 2

Particularly advantageous is the connection of the ECG module 10 via only one connection, which thus the supply voltage from eg 220V to the ballast module 10 and simultaneously supplies at least one consumer, eg the light modules 12, 14 with direct current.

The light modules 12, 14 are formed as plate-shaped support elements whose dimensions are larger than those of the conductor support module 4, but they are basically rectangular in plan view, so have longer longitudinal edges as transverse edges. On the undersides of the light modules 12, 14, a plurality of LED modules comprising one or more printed circuit boards are mounted with LEDs arranged thereon. Preferably, the light modules 12, 14 made of aluminum or other good thermal conductivity material, in particular metal, so that they act as a heat sink.

It is also within the scope of the invention that the light modules have the same dimensions as the conductor carrier module 4.

In the direction of radiation in front of the LED modules, that is to say on the underside, optical systems covering the LED modules are detachably fastened to the light modules 12, 14.

In the preferred embodiment, the light modules 12, 14 are designed as heat sinks, in particular for use with high-power LEDs. In a further development, cooling fins are provided for this purpose on the light module, preferably on the upper side, as in the embodiment according to FIG FIG. 6 shown, which comprises a plurality of transverse to the longitudinal direction of the light module 16 extending cooling fins 16a, which has an upper-side, central recess or free surface for the placement of the in Fig. 6 not shown busbar module.

At the bottom of these light modules 16 can also several LED modules are arranged parallel to each other, see Figure 7.

The line element 2 or line carrier element 4 according to the invention thus provides a one-piece, rigid contacting element between the ECG module and the at least one light module / LED module, which can also realize the essential carrying function of the luminaire. The FIGS. 8 and 9 show an alternative embodiment of a lighting device according to the invention, designed as an outdoor lamp, in particular a pole light using a conductor carrier module 20 according to the invention. In this embodiment, the ECG module is integrated in a mast approach 18, which is fastened on top of a mast, not shown. On the upper side connected to this mast extension 18, the box-shaped conductor carrier module 20 is mounted electrotechnically coupled, which has 20a-20e on its underside connectors, of which 20a-d for the connection of four parallel to each other and transverse to the longitudinal extension direction of the conductor carrier module 20 arranged light modules 22, 24th , 26, 28 are formed, which are electrically and detachably connected in the installed position with the connectors on the underside of the power carrier. Connector 20e, however, serves for connection to the ECG module in the mast approach 18th

Additional stability is given to the lamp by a rectangular, open-sided frame 30, which includes the light modules 22, 24, 26, 28 in the installed position like a clip and is detachably connected at its rear end to the mast extension 18. The frame 30 is mounted on the mast extension 18, then the line module 20 is attached and then successively the light modules 22, 24, 26, 28 are used, which also contain an interface.

The FIG. 10 shows the realizable by the invention modular design of lights of any size and light output. This can be done by two or more of the in the FIGS. 4 and 5 illustrated damp-proof lights are connected to each other via connection carrier 32, 34, which extend in the installed position like a bridge between two parallel juxtaposed lights 36, 38 and connect them so firmly to a unitary structure together. Of course, more than two lights can be coupled together by this training.

FIG. 11 shows a perspective view of a conductor carrier module 40 with a formed from transparent plastic top plate 40a. Good is the embedded in the top plate 40a in the injection molding process conductor 40b made of copper recognizable, which extends in the plane defined by the top plate 40a within the plastic of the top plate. In addition, a plug element comprising a plurality of contact pins connected to the conductor track 40b is also injected in the top plate 40a, ie integrally integrated. Thus, the conductor carrier module 40 forms an integral, ie one-piece and inherently IP-safe component.
