Description

The present invention relates to a lighting system comprising at least one lighting unit comprising a light segment which is configured to receive at least one light source or at least one light emitting means, and at least one connecting element which is at least partially electrically conductive and at one end of the light segment with this mechanically and electrically is connected, with at least one connector having at least one about a connector center axis (hereinafter also referred to as central axis) rotating element and at least one mechanically connected to the revolving element or formed by the rotating element electrical conductor, wherein the connecting element of the lamp unit with the circulating member of the connector is mechanically connected and thereby the at least one lamp unit with the connector is mechanically and electrically connected.

The present invention relates in particular to a lighting system with elements (lighting units, in particular rails) which can receive or illuminate lighting means, and nodes (also referred to below as connectors or connection modules) to which one or more of these elements or lighting units can be connected. The light units are easy to attach to the connectors. The angles at which the lighting units can be connected to the connectors are largely freely selectable. Optional joints, especially hinges, ensure that the lighting units are pivotable. The lighting units carry power from one node (connector) to the next. The connectors carry power from one light unit to the next.

There are many rail systems that are generally attached to ceilings, embedded in ceilings or suspended from ceilings.

The angles at which the rail elements are in relation to one another are generally 90 ° or 180 °. In the US 3,840,842 is described a node to which in addition at an angle of 45 ° or 135 ° can be mounted elements that can accommodate lighting. In the WO 2013/070429 A1 also connectors are described, to which up to 8 elongated elements at an angle of 45 °, 90 °, 135 ° and 180 ° can be attached.

According to the orientation of the light systems on the ceiling, it is generally linear constructs (light bands) or flat (two-dimensional) constructs that are possible with the known rail systems. Exception is the WO 2006/044859 A2 in which it is described how lighting elements can be fastened at predetermined angles, not only horizontally, to connecting elements. Furthermore, the describes US 2012/0201021 A1 Fasteners in which glow sticks can not only be fixed horizontally at 90 ° and 180 ° angles, but also vertically.

As far as the known rail systems have connectors (connection modules), this is often a considerable installation effort for connecting the lamp units connected to the connectors.

The design options with known light rail systems are very limited because they are on the one hand often only linear or surface configurable or on the other hand are configurable only in certain predetermined angles. Constructs that grow up on the walls like plants or go around the corners are just as impossible as polyhedron or truss structures.

It is therefore an object of the present invention to reduce the assembly effort in a lighting system.

The previously derived and indicated object is achieved by a lighting system according to claim 1.

Furthermore, the object is achieved according to a second teaching of the present invention by a lighting system according to claim 2.

The lighting system according to the invention is characterized in that it can be mounted quickly and easily, even under power or voltage. Another advantage is the high flexibility in configurability. Thus, the luminaire system according to the invention allows in a simple manner the arrangement of a plurality of luminaire units as a designed (two-dimensional or three-dimensional) network, which may optionally have multiple feeders for electricity. The electrical connection always runs through the connection of the lighting units, so that many lighting units manage with only a single power feeder or power supply. In principle, however, several power feeders can be connected at different locations to the lighting system or two- or three-dimensional network / structure.

By a two-dimensionally shaped lighting system is meant one in which all the lighting units and connectors of the lighting system lie in one plane. This includes luminaire systems which are linear, ie form a band extending between two ends (connector followed by a luminaire unit, again followed by a connector, etc.), or luminaire systems in the form of a circle, triangle or polygon. In this case, the lighting units and connectors can be arranged exclusively on the contour of the circle, triangle or polygon or in addition also other lighting units and / or connectors traverse the circle, the triangle or the polygon and thereby form a planar structure.

A three-dimensionally shaped lighting system is one in which one or more lighting units and / or connectors extend in planes other than other lighting units and / or connectors and / or extend at an angle to other lighting units and / or connectors. In other words, spatial structures of luminaire units and connectors are produced here.

For example, if the light segment is triangular, then it has three ends (the corners are defined here as ends). If, for example, the light segment is quadrangular and can be electrically connected to a connector via each of the four corners, the light segment accordingly has four ends. Single or all Luminaire units can thus have any number of connecting elements, triangular lamp units, for example, three connecting elements, wherein one can be provided at each corner of the respective light segment. It should be emphasized that the connecting elements need not necessarily be provided at the corners or ends of the respective light segment, but may also be arranged at other locations.

Basically, it is also in this case conceivable that a pivotability is given between the connecting element and the peripheral element, namely, for example, when an elastic material is used for the one-piece component.

According to a further embodiment, (in the case of the presence of a plurality of body portions constituting the connector) each body portion forms a circumferential member, in particular a rotationally symmetric orbiting member, of the connector. As will be described hereinafter, the body sections may have different cross sections (relative to a section perpendicular to the connector center axis). In particular, it is conceivable that a plurality of body sections or circumferential elements are plugged together in the axial direction, wherein each body portion in particular with a connecting element of a lamp unit mechanically and electrically, in particular in one piece, is connected.

In the optional case that each body portion is connected to a connecting element, it is conceivable that some or all body sections, in particular centrally or coaxially to the connector center axis, have a plug on the top side and a socket corresponding thereto on the underside or vice versa (top-side bushing and underside thereto corresponding plug).

In particular, it is conceivable that the inner contour of the first body portion and the outer contour of the second body portion is circular, wherein in particular, the first body portion has a ring shape and the second body portion has a ring or disc shape. It is preferred if the connecting element contacts the inner contour of the first body portion and the outer contour of the second body portion.

For example, an electrical input can be used to supply power to a (relatively large) lighting system at various locations. An electrical output can be used, for example, to connect external consumers (power consumers), such as sensors, spots or the like. Also, power supplies of electrical equipment, e.g. Music systems, or chargers for smartphones, computers, etc. could be connected here and supplied with electrical energy. With the lighting system according to the invention, these external consumers can be supplied with voltage and the voltage can be kept safe. The sensors mentioned by way of example could also correspond with the lighting system or else with individual lighting units of the lighting system (be electrically interconnected), whereby sensors such as motion detectors, brightness sensors, smoke detectors, light barriers or the like may be mentioned.

It should be noted that the light segment does not necessarily have to have lighting means, but only has to be suitable for being able to receive at least one light source. Light sources are in particular gas discharge lamps, light emitting diodes and / or incandescent lamps. If the light segment has no light sources, the light segment is, for example, a light profile, For example, an aluminum profile, in which at least one of the aforementioned bulbs can be used.

In particular, the invention provides that in the assembled state of the lamp unit and connector, the connecting element is pivotable relative to the light segment in a plane in which the connector center axis extends.

According to one embodiment of the invention it is provided that the lamp unit, in particular the light segment and / or connecting element, at least in sections, preferably completely, consists of a flexible material.

It is also conceivable that the connecting element with the light segment in one piece (integrally or made of one piece) is connected, so in particular no hinge / hinge is provided.

A nodal point, to which light bars are attached at arbitrary angles around a central axis, opens up manifold two-dimensional design possibilities ( Fig. 10 ). Joints on the lighting units or around the junction opens the world of three-dimensional design ( Fig. 8 and Fig. 9 ). A simple, quick-to-handle connection of the rods to the node facilitates experimental design with these elements. The current routing in the luminaire units from node to node makes it possible that larger constructs with few points for power supply can be realized.

Hereinafter, various features of the present invention will be defined and explained with reference to the drawings.

Nodes, also called connectors or connection modules, according to the present invention are in particular:
Elements with an imaginary central axis (connector center axis) 1a and a body or body portion revolving around the central axis, for example in the form of a circular plate. When in the present invention of "circumferential" is mentioned, in particular a circular shape is meant, ie "circularly circulating".

Around the central axis, luminaire units 2 can be plugged in, staples or the like. be attached.

The lighting units can be plugged at any angle to the junction. The only limitation is that the width of the lighting units does not allow for infinite number of connections.

The connectors carry power from the attached lamp units to other mounted lamp units. (at least two poles, e.g., low voltage direct current).

Further explanation:

Special connectors 3 provide mounting options for mounting on a wall or ceiling. Additionally or alternatively, connectors 4 are conceivable which offer the possibility of feeding current into the system.

The connectors may also provide attachments for other lighting units outside of the body or body portion revolving around the central axis.

Connectors can be connected to other connectors to attach more light units.

Connectors may also be illuminated (having a lighting means).

Rails, also called lamp units, according to the present invention are in particular:
Elements that are capable of constructively connecting connectors and carrying power. Preferably they are illuminated (eg aluminum profile rails 2b with inserted LED strips)

Further explanation:

The lighting units can also be flat and connect three or more connectors. The corners then form the ends to which the connectors are connected.

Some or all of the lighting units may also be unlit, i. have no bulbs.

The lighting units are also suitable to be connected only to a node.

Joints, in particular hinges or hinges, according to the present invention are in particular:
Elements that allow movement at 90 ° to the body or body portion (definition node) revolving around the central axis.

Conceivable is a classic hinge at the end of the lighting units between light segment (eg LED strip in aluminum profile) and connecting element ( Fig. 1 ).

It is conceivable a rubber element at one end of the lamp unit between light segment and connecting element ( Fig. 2 , No. 2c). By way of example, a pivot axis x ₁ and a rotation axis x _{2 are also} shown here, around which each light segment _{2 a} can be pivoted or rotated. The pivot axis x ₁ is shown here in the plane of the drawing, so runs here by way of example in a plane perpendicular to the Vebindermittelachse. An alternative or additional pivot axis x ₁ but also parallel to the connector center axis and thus perpendicular to the two in Fig. 2 drawn axes x ₁ and x ₂ run.

It is conceivable that parts or the entire lamp unit is made of flexible material (thin wood, spring steel, Alucobond) and thus the lamp unit or a portion thereof itself is the joint ( Fig. 7 No. 2).

It is conceivable that the connection between the node and the lighting unit at the same time represents the joint (for example: The body or body portion of the node surrounding the central axis is formed by a round wire which is at the same time an axis for the joints.

Embodiments will be described below and explained with reference to embodiments shown in the figures.

According to a further embodiment, it is provided that the lamp unit has a profile, run in the LED strip, and the lighting system is operated with low voltage.

An advantageous embodiment of the invention is therefore a low-voltage lamp with LED profiles. There is no danger to the user in the low-voltage range, which means that the required precautions are considerably lower and therefore the constructive effort is more manageable. An obvious consequence of this is the illumination by LED strips. Yet another obvious consequence is the use of a profile that is not only suitable for constructively connecting connectors but also for accommodating a light scattering profile, providing space for LEDs and providing additional space for parallel current conduction.

According to a further embodiment, it is provided that the hinge or the hinges are arranged at the ends of the lamp unit, between the luminous segment (s) and the connecting elements (plug or clip elements).

The described hinges or joints ( Fig. 1 No 2c) are located just before the end of the lighting units between the segment that is generally illuminable ( Fig. 1 No. 2b) and the linking elements ( Fig. 1 No 2d) to the junction (connector / bracket / etc). The joints can be classic hinges, but also made of elastic material.

This design moves the hinge points close to the node, which is advantageous for the geometry of the constructs that are built from the light system. From a mechanical and design point of view, the ideal would be if the lighting units could meet at one point. By approaching the joints at the junction one comes quite close to it. (Forces of rods are derived without moment when the rods meet on a point.) Another advantage lies in the spatial delineation of the different functions: fastener, joint, light segment. This spatial separation simplifies technical development.

According to a further embodiment, it is provided that for fastening the lamp unit or lamp units with the node connecting elements (plug) are arranged at the ends of the lamp unit, which engage between axially spaced from each other around the central axis elements at the node.

It is therefore described a connector ( Fig. 3 ), which clearly defines the position of the plug axially to the node, but allows radially any angle. Between two or more radial elements ( Fig. 3 No. 1d), such as disks or plates, the connecting element (plug) ( Fig. 3 No. 2e) at the end of the lamp units. In contrast to other plugs, it does not engage in one or more holes but in one or more radial lighting units.

According to a further embodiment, it is provided that for attaching the lamp unit or lamp units to the node, a clamp-shaped connecting element is arranged at the ends of the lamp unit, which engages around a circumferential axis of the element of the connector.

It is therefore described a connector ( Fig. 4 ) having the reverse geometry described in claim 9. A kind of clip ( Fig. 4 No. 2f) engages around one or more radial elements ( Fig. 4 No. 1e) at the junction. While in claim 9, the male (plug) is on the lamp unit and the female (female) is at the node, in claim 10, the female (female) to the lamp unit and the male at the junction. This results in the same advantages as in claim. 9

According to a further embodiment, it is provided that the connecting element (plug or clip or clip-shaped connecting element) has contacts with which the current transmission from the node takes place.

It is therefore described that the electrical and the constructive connection are combined in the plug or clip component. The configuration of the lighting system is thus easier, since few interfaces must be connected.

According to a further embodiment, it is provided that at least one of the peripheral elements at the node into which engages the connector or the clip (the bracket-shaped connecting element) has an undercut, wherein the plug / clip engages in the undercut / undercuts.

The connecting element at the end of the lamp units can thus snap in at the junction. The node has one or more radial elements, the z. B. as a plate, a sleeve or a disc can be configured. These elements have an undercut ( Fig. 5 No. 1f), that means they have a circumferential brim, edge, thickening or similar in the outer area. The connecting element, on the lamp unit is pushed from the outside between or over one or more radial elements and can at the brim, edge o.ä. engage. Conveniently, this compound is reversible. To solve the connection, for example, a button must be pressed or a mechanical or magnetic force must be overcome ( Fig. 5 No. 2g).

According to a further embodiment, it is provided that the connecting element has a ring which is adapted to be pushed over the central axis of the connector, and which in particular is firmly connected to the remaining connecting element.

The connecting element at the end of the lamp units consists therefore exclusively or additionally of a ring ( Fig. 6 No. 2h). This ring can be attached to the junction by passing over an axial (cylindrical) element ( Fig. 6 No. 1g) at the junction. Or by an axial (cylindrical) element, which represents a part of the connector through the ring is pushed. The ring is so thin that several of these rings fit over the axial element.
The most stable attachment to an axle can be achieved by embracing the axle. Also, the orientation towards the axis is ensured when a rod ends in an eyelet, which engages around the axis. In order to fix several luminaire units, it is necessary that the rings are flat and the axis long. (Length of axis / thickness of rings = number of rings that can be accommodated)

For attachment, either the ring is inserted over an axle or the axle is inserted into the rings. In order to prevent the rings from sliding off the axle again, the axle can be reversibly fitted with end caps ( Fig. 6 No. 1h) which are larger than the inner diameter of the rings.

These rings may also advantageously occur in addition to the connectors or brackets described in the claims 9 and 10. When assembled by the user, the clips would then be attached to the connectors and then the rings placed around a cylindrical axial body. Subsequently, if necessary, a securing element is attached, which prevents slipping out of the rings.

This construction of the connection of node and lamp unit would have the advantage that the plug / clamp defines the axial locking, while the ring optimally aligns the lamp units to the axis and prevents the plug / clip from slipping out.

According to a further embodiment, it is provided that the hinge is formed by the fact that the lamp unit is made continuously of flexible material, which is particularly suitable to deflect altogether.

With the processing of flexible material such as spring steel, thin plywood, plastic material or Alucobont, the joints could benefit from this flexibility result ( Fig. 7 No. 2). It is conceivable that the material runs like a bow (arrow and bow) between the connectors. The simple construction would be advantageous.

According to a further embodiment, it is provided that the connector or connectors have a mounting option that is suitable to carry the lighting system and to provide power.

The greatest design variety for the user arises when the connection to ceilings or walls takes place on the connectors. The stability of these light system constructs is best when they are connected to the connectors. Through such connections, the power supply also makes sense.

These connections can be realized via a cable or cable or via a rod which ends in a flange or the like.

In Fig. 11 is a lighting system 5 is shown, in which the lamp units 2 each have a light segment 2a, for example in the form of profiles, which are integrally connected at the end visible in the figure with a connecting element 2d, in which an opening 7 provided in the form of a bore is. Via this bore 7 in the connecting element 2d a plurality of lamp units 2 of the type shown can be set in the axial direction on a two-part connector 1 and thereby plugged together. According to the embodiment in Fig. 11 For example, the connector 1 has a plurality of body portions 6a, 6b, and 6c, the body portions 6a and 6b having a relatively large diameter, and the pin-shaped body portion 6c having a relatively small diameter. Here, the body portions 6b and 6c are integrally connected to each other and the body portion 6a can be placed after mating with a plurality of lamp units 2 on the body portion 6c, for example screwed to fix the lamp units 2 to the connector 1 and the connector 1 with current / voltage to supply.

Fig. 12 shows an embodiment in which the lamp units 2, each with a peripheral element 6d and 6e of a connector 1 are made in one piece. The connector 1 is designed here in several parts, thus has a plurality of circumferential elements or body portions 6 d and 6 e. Each of the two illustrated body sections 6d and 6e has on the upper side a recess (bushing) and on the underside a complementary projection (plug), so that there is an electrical connection in the assembled state. In this embodiment, therefore, the connector 1, at least a part (body portion) thereof, with the respective lamp unit 2 is integrally connected. Although this is shown here only for one end of the lamp unit, it can preferably also be provided on the respective other end (not visible here) or the other ends of the lamp unit 2.

Fig. 13 Finally, shows an embodiment in which the connector also has several (here two) circumferential elements or body portions 6f and 6g, which lie in this case in each other or in a common plane and here concentric to each other (with constant distance from each other) are. The inner, here disc-shaped, body portion 6f has a smaller cross section than the outer annular body portion 6g. The body portions 6g and 6f are interconnected by two webs diametrically opposed to each other. In the angular range from the one web to the other web around the connector center axis, the respective lamp unit 2 with the connector can be arranged in arbitrary positions around the connector central axis. Each of the two continuous angle ranges is here for example about 175 °.
