Description

 lighting system

The present invention relates to a lighting system with at least one

Luminaire 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 connected, with at least one connector, the at least one element surrounding a connector center axis (hereinafter also referred to as center axis only) and at least one mechanical element with the revolving element

connected or formed by the peripheral element electrical conductor, wherein the connecting element of the lamp unit with the peripheral element 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 lamps, and nodes (hereinafter also referred to as connectors or connection modules) to which one or more of these elements or

Lamp 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 US 3,840,842 a node is described, to which in addition at an angle of 45 ° or 135 ° elements can be mounted, the

Can accommodate bulbs. In WO 2013/070429 AI 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, which describes how light elements at predetermined angles - not only horizontally - can be attached to fasteners. Furthermore, the US 2012/0201021 AI describes fasteners in the glow sticks can not only be attached horizontally at an angle of 90 ° and 180 °, but also vertically.

As far as the known rail systems have connectors (connection modules), this is often a considerable installation effort to connect the

Luminaire 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 according to a first teaching of the present invention in a lighting system

 with at least one lamp unit (in particular rail, i.e. oblong

 Luminaire unit], containing a light segment (light element), which is configured to receive at least one light source or at least one

Comprising at least one connecting element (in particular with another component zusammensteckbares element, i.e. plug / socket), which is at least partially electrically conductive and at one end of the

 - That the lamp unit with the connector in different positions about the connector center axis (that is, in different angular positions or

 Positions around the circumference) around and in each position the

Lamp unit is mechanically and electrically connected to the connector and

- That a plurality of lamp units are mechanically and electrically connected to a common connector and in particular form a two-dimensional or three-dimensionally shaped lighting system.

Furthermore, the object according to a second teaching of the present invention in a lighting system, in particular one as described above

Lighting system,

 - With at least one lamp unit (in particular rail), containing a

 Light segment (light element), which holds at least one

form three-dimensionally shaped lighting system. 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, a plurality of current feeders can be connected to the light system or I two- or three-dimensional network / structure at different locations. 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.

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.

A node, at around any central axis at any angle

Illuminated rails are fastened, opens manifold two-dimensional

Design options (Fig. 10). Joints on the light units or around the junction open up the world of three - dimensional design (Figs. 8 and Fig. 9]. A simple, quick-to-use 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 central axis) 1a and a body or body section encircling the central axis, eg in the form of a circular plate If in the present invention the term "peripheral" is used, it is meant in particular a circular shape, 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 DC).

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 for more

Lighting units can be attached.

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 (e.g., aluminum profiles 2b with LED strips inserted).

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. none

Have light bulbs.

The lighting units are also suitable only to a node

to be connected.

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 (for example, 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 and an axis of rotation xi, x _{2 are} drawn to the light of each segment can be pivoted or rotated 2a here as well. The pivot axis xi 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 xi but can also parallel to the connector center axis and thus perpendicular to the two axes drawn in Fig. 2 xi 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 lighting unit or a

Section of which itself is the joint (fig. 7 no. 2). It is conceivable that the connection between the node and the lamp unit simultaneously represents the joint (eg: 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 the

Illustrated Illustrated embodiments explained.

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

Low voltage is operated. , ,

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

offers additional space for a parallel power supply. 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 lamp units between the segment, that in general

is illuminated (Fig. 1 No. 2b) and the linking elements (Fig. 1 No 2d) to the node (plug / 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 hit 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

 Luminaire unit or lamp units with the node connecting elements (plug) are arranged at the ends of the lamp unit, which engage between axially spaced around the central axis rotating elements at the node.

It is therefore described a connector (Fig. 3), the location of the

Connector clearly defined axially to the node, radially but allows any angle. Between two or more radial elements (Fig. 3 No. ld), e.g.

The connecting element (plug) (Fig. 3 no. 2e) at the end of the lamp units is inserted into the panes or plates. 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 fastening the

Luminaire unit or lamp units at the node a clip-shaped connecting element is arranged at the ends of the lamp unit, which engages around a central axis of the element of the connector.

It is therefore described a connector (Fig. 4), which has the reverse geometry, which was described in claim 9. A type of clamp (fig. 4 no. 2f) engages around one or more radial elements (fig. 4 no

Junction. While in claim 9, the male (male) to the

Is light unit and the female (female) is at the junction is in

Claim 10, the female (socket) on 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 therefore am

 Snap in node. 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. Lf), that means they have in

Outside a circumferential brim, edge, thickening o.a. 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.

engage. Conveniently, this compound is reversible. To solve the connection, e.g. Press a button or overcome a mechanical or magnetic force (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 in particular fixed to the rest

Connecting element is connected.

The connecting element at the end of the lamp units is accordingly

exclusively or additionally from a ring (fig. 6 no. 2h). This ring can be attached to the junction by sliding it over an Axial (Cylindrical) element (Fig. 6 No. lg) at the junction. Or by an axial

(Cylindrical) element, which is 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, the axle can be reversibly provided with end caps (Fig. 6 No. lh) 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 between the connectors like a bow (bow and arrow).

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. Also the stability of these

Light system constructs are best when tied to the connectors. By such connections is meaningful as the

Power supply.

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, 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 to the end visible in the figure with a connecting element 2d, in which an opening 7 in Form of a bore is provided. 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, the connector 1 has a plurality of body portions 6a, 6b and 6c, wherein the

Body portions 6a and 6b have a relatively large diameter and the pin-shaped body portion 6c has a relatively small diameter. In this case, the body portions 6b and 6c are integrally connected to each other and the body portion 6a is placed on the body portion 6c after being mated with a plurality of lamp units 2, e.g. screwed to the
