Description

The present invention relates to a modular luminaire system which comprises at least one luminaire base and a luminaire support structure for fastening the luminaire base.

STATE OF THE ART

Various lighting systems for illuminating sales facilities, representative rooms, in private and in public buildings are known from the prior art.

So revealed DE 10 2016 101 769 A1 a modular luminaire system with a luminaire base and a luminaire support structure, which is designed as a support rod system. The base body of the luminaire is mechanically fastened via a ball joint to the support rod system, and an additional electrical connection is provided via a cable socket and a connecting cable, whereby the mobility of the ball joint is disadvantageously restricted by the separate cable connection. Use as a track-mounted luminaire is not possible. Universal use is therefore restricted, and an electrical power supply that is separate from the mechanical fastening means that a great deal of effort is required during installation and the visible cable impairs the visual appearance.

In the DE 20 2008 002 365 U1 a luminaire construction is shown in which a luminaire can be connected to a known busbar via an adapter. The lamp has a swivel arm and an adapter. The arm has a first bracket part and a second bracket part. At its first end, the arm is connected to the adapter, which is plugged into the longitudinal passage of the busbar and is intended for electrical tapping. A vertical first axis of rotation extends through the first arm end into the adapter. A horizontal second axis of rotation runs through the second arm end. This enables a rotation range of almost 360 ° to be achieved. In addition, the DE 20 2008 002 365 U1 a busbar, which consists of a support profile, preferably of continuous aluminum casting, and two meandering insulation strands, preferably made of plastic, inserted laterally therein. A pair of current conductors is partially embedded in each of these insulation strands. A passage allows access to the electrical conductor. However, this luminaire construction can only be used explicitly for a power rail and cannot be used for different lighting purposes.

The DE 196 52 401 C2 discloses a comparable busbar system with a busbar and lamp adapters arranged thereon, which contain lamps and establish a connection to the conductors of the busbars by means of electrical contacts. A busbar is attached to a support profile. The carrier profile has a carrier web and a web with a locking head. The busbar has a recess for receiving the web and the locking head of the support profile. An insulated cable strand is arranged in the conductor rail above and below the recess, which is covered on the side of an outer wall by a material layer of approximately 1 mm thick. A spotlight is attached to a cable and is brought into electrical contact with the conductors in the conductor rail via a lamp adapter. Two contact pins are provided when the lamp adapter is attached to the conductor rail system. Here, too, only a busbar system for lighting purposes is shown, with universal use remaining limited.

In the DE 201 16 392 U1 a busbar system for luminaires is disclosed. The busbar system comprises supply lines, insulation, a laminating device, adapter units and lights. The supply lines are surrounded by the insulation. The insulation is in turn surrounded by the laminating device. The lights are attached to the power rails via the adapter units. The body of the adapter unit has a recess. The busbar is inserted into the recess in such a way that insulating rings each protrude into and through openings. By pressing a cover against the body, the busbar is pressed against contact elements, so that electrical contacts are provided. Nevertheless, the lighting system can only be used on power rails, so that other solutions have to be used for different lighting purposes.

The DE 298 16 627 U1 shows a low-voltage lighting system with a busbar and a flat insulating body as a mechanical support. The insulating body is coated on its opposite surfaces with conductor strips made of electrically conductive material. A lamp holder has two clamping elements, which are connected to each other by insulated screws above and below the conductor rail. Contact pieces press against the conductor strips so that an electrical contact is made. A pin made of an insulating material is arranged on the conductor rail to simplify assembly and to improve the mechanical strength of the lamp holder. Underneath the pin, two joint pieces which are electrically insulated from one another are mounted and which can be pivoted together in the plane of the busbar and on which are two electrically insulated carrier pieces and are mounted, which can be pivoted together in a plane perpendicular to the plane of the busbar. Here too, only use as a busbar system is provided.

In the DE 39 19 201 C2 a track with light is shown. A busbar is formed by two rods made of metal, the rods having blind holes, in each of which a plastic bolt is arranged. A lamp is movably attached to the rods via an adapter, the adapter being formed by two identical profile material elements. A plastic pin is arranged as an insulator between the profile material elements. The adapter has an isolator that isolates the adapter from the rods.

Furthermore, in the DE 94 05 996 U1 a low-voltage radiator is shown, which is attached to two power rails by plugging. Two contact springs with a U-shaped profile are provided for attachment. A cylinder screw and a screw serve to supply the electrical current. A cover with a lamp can be swiveled around an upper joint and a lower joint.

Generic is in the DE 94 04 962 U1 discloses a busbar, which consists of a U-shaped profiled support profile and a flexible insulated cable, which has an insulating cable sheath and a cable core. The carrier profile is made of metal.

In parallel, the DE 299 09 467 U1 a busbar with an insulation profile that has a lenticular cross-section, the insulation profile being made of a plastic such as polycarbonate. Three electrical conductors are embedded in the insulation profile. Each conductor is accessible through a slot. An adapter has two curved arms. At the upper end, each arm carries a locking cam, so that the arms close tightly around the insulation profile of the busbar and lock together. Each adapter has three contact blades, which each protrude from an insulating base and come into contact with one of the conductors of the busbar when the arms are closed.

Is also in the DE 10 2004 042 821 A1 discloses a spotlight, which is designed for attachment to a busbar by means of a busbar holder. A support arm is attached to the track holder, to which a frame is attached.

Furthermore, in the DE 10 2008 055 864 A1 an LED light shown with a support arm. A first articulated connection is provided at the transition point between the support arm and a heat sink. A second articulated connection is provided at the transition point between the support arm and a lamp ballast. The first articulated connection can be provided for pivoting the heat sink around a horizontal axis and the second articulated connection for pivoting the heat sink around a vertical axis.

Is also in the DE 195 10 507 C2 an electrical lighting system shown with a busbar that is held by ceiling brackets. Electricity can be fed into one of the ceiling brackets. Lamp holders can be attached anywhere without tools, without having to remove the busbar. The busbar has rubber-insulated current guides, and contact tips with two brackets drill into the rubber jacket of the current guides to make electrical contact.

All of the aforementioned busbar systems lack the fact that the respective luminaire can only be connected to the busbar. In some cases the pivotability and thus the direction of illumination is restricted. A combination with other luminaire designs without a track system is not possible. As a rule, the mechanical fastening is structurally and functionally separate from the electrical power supply, with technical, economic and aesthetic disadvantages arising both in the manufacture and in the installation and operation.

A disadvantage of the prior art is that different lighting constructions have to be used for different lighting applications such as floor lamp, pendant lamp, wall lamp, track light, table lamp etc. This requires a pre-selection of different lighting products, each with their own individual technical surroundings, connections, types of fastening, etc. Therefore, for aesthetic reasons, no uniform design principle can be implemented. In addition, if at all, only a small amount of identical parts can be used for different lighting applications, so that the costs for heterogeneous lighting scenarios are increased. Ultimately, any possibility of aligning the lighting areas of each individual lamp is severely restricted by mechanical and / or electrical design principles.

The object of the present invention is to propose a universal lighting system for diverse and dynamically changeable lighting applications, which is subject to a uniform construction principle, a uniform luminaire base body being usable as the same part, This saves costs and an aesthetically pleasing lighting concept can be achieved with a high degree of flexibility in luminaire alignment.

This object is achieved by a lighting system according to independent claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

DISCLOSURE OF THE INVENTION

A modular luminaire system is proposed which comprises at least one luminaire base and a luminaire support structure for fastening the luminaire base.

It is proposed according to the invention that at least one adapter element is included, which is designed to be both electrically contacting and mechanically fastening, in particular axially fastening, each luminaire base body being connectable to the luminaire support structure via an adapter element in each case, and as a swivel joint about a longitudinal axis of the adapter element relative to the luminaire support structure is rotatable.

The modular luminaire system according to the invention comprises at least one luminaire base body which is used for various assembly and lighting tasks. The modular lighting system can be used, for example, as wall and ceiling lights, pendant lights, floor and table lights and spotlights. This enables a holistic solution through a modular system by means of a combination of identical parts, which are put together to form a variety of luminaires, which can be adapted to room geometry, position in the room, and the specific lighting task.

A conductor rail, in particular a plurality of conductor rails and / or a supporting rod system and / or a base element can advantageously be used as the luminaire support structure. The busbar can be connected to the power grid, for example, with at least one cable. Current is thus conducted over the busbar, the electrical contacting adapter element being interposed between the busbar and the luminaire main body. With this, the current is led from the busbar via the adapter element to the luminaire base. If a busbar is used as the luminaire support structure, a connecting element for receiving the adapter element can be arranged on a jacket section of the busbar, as a result of which an electrical and mechanical connection can exist between the busbar and the connecting element. With the busbar, the modular lighting system can be designed, for example, as a standing, hanging or ceiling lamp. The track can itself serve as a linear light source. The module system can thus comprise point-shaped and linear light sources, and these can be compatible with one another through universal interfaces.

Excellent advantages result from the factor of using the same parts, which is expressed in lower development costs, lower storage costs and functional design for a simple design solution. This creates an aesthetic advantage through the possibility of holistic design solutions.

The support rod system can comprise at least one support rod, in particular a plurality of support rods, the adapter element being arranged in the support rod, preferably at least at one end of the support rod. Each adapter element can be connected to a luminaire base body, thus providing an electrical and mechanical connection through the adapter element between the luminaire base body and the support rod. As a result, the current can be conducted from the support rod via the adapter element to the base body. A lighting system comprising the support rod system can be used, for example, as pendant lights.

If a base element is used as the luminaire support structure, the base element can have a receiving part into which the adapter element can be inserted for attachment to the base element. Furthermore, the luminaire base body can be designed with a contact device, via which the luminaire base body can be electrically connected and mechanically attached to the adapter element. This embodiment can e.g. can be used as wall and ceiling lights. The mechanical fastening is intended, in particular, to prevent the luminaire body from axially detaching from a fastening axis of the luminaire support structure. Advantageously, a further degree of mechanical freedom should be provided in the sense of being freely rotatable about the fastening axis.

When the luminaire base body is fixed to the luminaire support structure, preferably to the busbar, to the support rod system or to the base element, the mechanical connection established via the adapter element provides a rotatability of the luminaire base body relative to the luminaire support structure about a longitudinal axis of the adapter element. The rotatability can be limited to a predefinable angular range, or unlimited rotatability, so that any rotational position can be assumed. The rotatability can be achieved by a swivel joint within the adapter element or by a The mechanical connection of the adapter element can be rotated with respect to a contact device of the luminaire main body. The mechanical connection between the luminaire base and the luminaire support structure can be secured against unintentional twisting and / or pivoting. A locking inhibition or a locking possibility of a twisting and pivoting movement can preferably be provided. Furthermore, the mechanical connection of the luminaire base body can not only be rotated by any number of degrees up to 360 ° and more about a longitudinal axis of the adapter element, but can also be pivotable about a further axis by a swivel joint preferably arranged in the luminaire base body, an additional one Swivel range of at least 90 ° can be achieved. In addition, the mechanical connection between the luminaire base body and the luminaire support structure can be secured by the adapter element against unintentional loosening or falling out of the luminaire base body.

Furthermore, an operating voltage, in particular between 46 V _DC and 50 V _DC , can be provided by the electrical connection between the luminaire base body and the luminaire support structure, the adapter element being able to carry a maximum current load of up to 1 A _DC , for example . However, much higher AC or DC voltages and higher currents are also possible. It is advantageous that this electrical connection can provide a reliable and safe contact with a very low contact resistance and maximum current carrying capacity. It is also advantageous that the electrical connection between the luminaire base body and the luminaire support structure is protected against short circuits and offers a high protection against contact, in particular an increased IP protection class against dust and moisture.

It is also advantageous that an identical luminaire base body in a wide variety of lighting forms, e.g. can be used as a floor lamp, hanging lamp, wall lamp, track light and ceiling lamp etc. This means that different luminaire designs are not required for different lighting applications and a high number of identical parts, in particular the complex and complex luminaire base body, which comprises the illuminant and suitable ballast electronics, is made possible.

It is therefore advantageous that a large amount of identical parts can be used for different lighting applications with the modular lighting system according to the invention, so that a design effort can be reduced. In addition, any alignment of the lighting areas of each individual luminaire base body can be made possible by the mechanical and / or electrical connection. As a rule, the connection of individual cables by a specialist is required when installing a luminaire, and is usually associated with the use of tools. In an advantageous embodiment, the adapter element can be mechanically and electrically non-detachably connected to a component of the lamp support structure, and can be mechanically and electrically detachably connected to the lamp base body, preferably without tools. To this extent, the luminaire base body has a contact device for mechanical accommodation and electrical contacting of the adapter element. The adapter element forms the interface of the luminaire support structure to the luminaire base body, and is mechanically fixed with the luminaire support structure, i.e. at least not detachably connected without tools and has an electrical connection to the power connection system, which is provided by the lamp support structure. The luminaire support structure in turn forms the mechanical attachment to the building, e.g. to the ceiling, wall or floor and provides the electrical power supply and possibly other control lines. The mechanical connection preferably enables axial rotatability about a fastening axis of the adapter element. The luminaire base bodies can thus be used as identical parts for a wide variety of lighting tasks, and the specific configuration of the adapter element can be adapted to the different configurations of the luminaire support structure. Thus, the connection of the actual luminaire base body via the adapter is tool-free, safe and easy for a user without specialist knowledge. Furthermore, a high-quality, sophisticated design solution is possible by avoiding visible disturbing details such as cable connections, screws.

In an advantageous development, the luminaire support structure can comprise at least one busbar, the luminaire base body with the adapter element being connectable to the busbar via a busbar connection element. Here, the busbar connection element is provided as a connecting element together with the adapter element between the lamp base and the busbar. It is advisable for this purpose to provide the busbar connection element and adapter element as a mounting unit, it also being conceivable and advantageously possible in application cases to arrange the adapter element in an articulated manner on the busbar connection element in order to provide a further alignment possibility for the luminaire base body.

It is also a good idea to manufacture the busbar from an extruded aluminum profile. The outer shape of the conductor rail profile is advantageously axially rotationally symmetrical or has an axial rotational symmetry, in particular the conductor rail profile is essentially circular. Alternatively, the conductor rail profile can also have a rectangular or other regular outer shape. With rising copper prices, manufacturing costs are saved if the busbars are made of lightweight aluminum. Furthermore, the costs are reduced by a simple and quick installation of the modular lighting system, whereby length adjustment can be achieved by shortening prefabricated profile bars. In addition, it is conceivable that the busbar can be formed in two parts, in particular with an upper part and a lower part, wherein either the upper part or the lower part is made of plastic. The two parts can also consist of aluminum.

In a further advantageous development, the luminaire support structure can comprise a support rod system, the luminaire base body being connectable to an axial end of a support rod via the adapter element. The support rod system can have at least one support rod, in particular a plurality of support rods. The lamp body can be connected to an axial end of the support rod via the adapter element. Essentially, the support rod can have a round cross-section; the support rod can preferably be made of stainless steel or aluminum. The support rod is advantageously designed as a tubular, into which a cable can be inserted, or it already has insulated copper or aluminum strands on the inside. A support rod can be easily shortened for length adjustment. An adapter element, a node, angle, or branching element or a further support rod can be attached or screwed on at one axial end.

In a further advantageous development, the lamp support structure can comprise a base element, the base body of the lamp being connectable to the base element via an adapter element. Basically, the base element can be formed from a base plate and a cylinder jacket section and offers installation space for an electrical connection, a ballast or the like. It is also conceivable and advantageously possible that the adapter element can be arranged in an articulated manner on a cover surface of the base element in order to form a further pivoting possibility. The base element can be made of metal or plastic. The base element enables the luminaire body to be attached to a wall or a ceiling, so the modular luminaire system comprising the base element can be used as a wall or ceiling light.

In a further advantageous development, the luminaire base body can comprise a housing, at least one light unit, in particular a COB LED light unit, and a contact device. In this development it is proposed that the light unit be arranged integrated in the housing. The COB LED (Chip on Board LEDs) can be provided as a compact light unit, wire bonding of the LED chip being arranged on a circuit board and then potted with silicone in order to provide a compact and energetically efficient illuminant. Furthermore, an opening for receiving the contact device is formed in a side wall or a cover or underbody of the housing. The contact device can have a keyhole contour, so that the adapter element can be inserted into the contact device through the keyhole contour. A joint is advantageously configured in the contact device, so that the contact device can be pivoted by means of the joint. In addition to mechanical holding and locking elements for fastening the adapter element, the contact device has electrical contact elements for contacting electrical contact surfaces of the adapter element, which are preferably spring-mounted. The contact can have radially concentric contact surfaces in the form of coaxial or chinch connecting sleeves, or can have a jack connection with axial contact surfaces, or a combination thereof.

In a further advantageous development, the luminaire base body can comprise an interchangeable lens and / or a diffuser, and / or a heat sink, and / or a control board, wherein a design of the control board can preferably be coupled to a design of the heat sink. In order to improve the possibilities for influencing the radiation of the light unit, the interchangeable lens can be arranged between the light unit and the diffuser, which, depending on the lighting scenario, has a scattering or bundle property and, if necessary, enables the light color and / or light intensity to be influenced. Different lenses can be provided for this so that, for example, different beam opening angles can be brought about by corresponding, preferably tool-free changing of the lenses. The diffuser can be used for light scattering. The principle of operation of the diffuser is based on diffuse reflection and refraction of the light. The diffuser can generate the scattering of light on its surface. The diffuser is advantageously made of a transparent material, for example glass, so that the light is refracted and totally reflected achieved. Furthermore, a honeycomb grid can be built into the luminaire base so that direct glare can be avoided. Due to the low height of the honeycomb grid, the honeycomb grid can be easily integrated into the luminaire body. The honeycomb grid can be made of aluminum or plastic, and the honeycomb grid can be black anodized or painted. As a result, the light can be absorbed by the black color, so that the lamp appears dark from any angle when switched off.

The light unit can have means for detaching or restoring a connection between the light unit and the heat sink without tools or tools. This makes it possible that in the event of a defect in the light unit, only that has to be replaced. For example, the means can comprise a bayonet lock or consist of a bayonet lock.

In order to dissipate heat generated by the light unit, the light unit can be thermally combined with that from e.g. Aluminum or copper existing heat sink connected, which can be shaped like a ribbed cylindrical metal block. The outer shape of the heat sink can follow an inner contour of the lamp housing, and can be annular or disk-shaped.

To control the modular lighting system, the control board is advantageously designed in such a way that a compact electronics unit can be achieved. Adapting the shape of the control board to the design of the heat sink enables improved cooling of the power electronic components, on the one hand, and a compact design of the main body of the luminaire on the other. The control board adjusts the supply voltage to the specification of the built-in lamp. Furthermore, e.g. Light intensity and / or light colors can be changed flexibly and comfortably. It also enables the control board to meet the requirements of the individual controllability of each individual light unit within the modular lighting system, and to allow each light unit to be parameterized internally to different light intensities and colors.

In a further advantageous development, the contact device can be designed as an electrical and mechanical connection of the adapter element, via which the luminaire base body can be electrically contacted and mechanically attached to the adapter element without tools, at least one two-wire, preferably a three-wire or multi-wire electrical connection being able to be established. The connection between the luminaire base and the adapter element is thus easy to assemble and disassemble. A spring-loaded locking of the connection prevents accidental loosening of the setting position of the adapter element. Furthermore, it is advantageous that, in a locked state, a free axial rotatability of 360 ° about the longitudinal axis of the adapter element can be achieved. The connection point between the adapter element and the contact device can thus provide anti-rotation protection with a defined torque, which prevents the set rotational position from being inadvertently rotated. The torque-inhibiting torque can be adjusted by a spring-loaded bracing of the mechanical connection, for example by a pre-tensioning mechanism of the pressure spring in the locking mechanism of the luminaire body, which clamps the adapter element. Through this connection, a voltage range, preferably between 46 V _DC and 50 V _DC , can be transmitted as a low voltage with reduced contact protection, the current being able to be carried in this connection up to a maximum of 1 A _DC . With this current, the light unit can be supplied, for example, to the COB LED light unit with a nominal output of 50 W or less. At maximum current flow, there is reliable contact with minimal contact resistance, whereby a short circuit or electric shock when touched can be avoided.

It is also advantageous that the connection is electrically safe to touch. When the adapter element is not connected and when plugging in or unplugging, a risk of a short circuit and accidental touching can thus be excluded.

In a further advantageous development, the contact device and the adapter element can comprise mutually complementary plug-coupling elements, in particular coaxial and / or jack-like plug-coupling elements, for the electrical contacting, the adapter element preferably being rotationally symmetrical, and further preferably the electrical connection regions being coaxial, are shaped like a hollow plug, banana plug, chinch plug or as a jack plug. Preferably, a hollow plug connection can be used for the power supply, which is coaxially shaped and can be freely rotated axially in a variety of ways for the transmission of direct or low voltage. Since a large number of compatible power supply units exist, a direct connection of a luminaire body to a commercially available power supply unit is conceivable with a correspondingly coordinated electrical connection assignment. An F plug, a BNC plug or a TNC plug from antenna technology can also be used as the coaxial plug, a BNC plug with a Bayonet lock offers high mechanical stability. In contrast to the BNC connector, the F connector and the TNC connector are threaded. Such plugs can be used for the transmission of direct currents and low and high frequency alternating currents, in particular for digital information transmission by means of frequency modulation such as Powerline etc. With such a coaxial structure, protection against external electromagnetic fields can be achieved. Alternatively or in combination, a jack plug can be used, which enables multi-pole signal transmission via axially offset contact sections of each pole. A shape as a jack plug enables a radially space-saving design while at the same time providing a multi-pole connection. A combination of axially and radially staggered contact surfaces of a coaxial jack-like plug-coupling version offers both high mechanical stability and multi-pole current routing and high contact reliability with free axial rotation.

In a further advantageous development, the luminaire base body can be rotated via the contact device both about a longitudinal axis of the adapter element and also about a further axis, preferably at right angles to the longitudinal axis of the adapter element, and further preferably by means of a joint of the contact device. Thus, in this development, the axis of rotation joint is provided by the mechanical connection of the contact device to the adapter element, the electrical contact device allowing at least limited, as a rule even unlimited, rotatability. The base body of the luminaire can be rotatable through the contact device about the longitudinal axis of the adapter element through a predefinable or any angular range, preferably through 360 ° or more. Furthermore, according to this development, the luminaire base body can be pivoted about a further axis, in particular at right angles to the axis of the adapter element, by at least 90 °, the contact device being able to be rotatably mounted in the luminaire base body. Any orientation of the lighting areas of each individual luminaire base body is thus made possible via the contact device, in particular via the joint of the contact device. The design of the adapter element is primarily designed for the axial rotatability about the longitudinal axis, while the contact device provides the further pivotability of the luminaire base body relative to the luminaire support structure. In order to secure the luminaire base body against unintentional adjustment of a rotational position and / or a swivel position, a required torque with respect to the longitudinal rotation about the adapter axis as well as about the transverse axis of the contact device, i.e. a certain stiffness should be provided. This can be achieved, for example, by a locking mechanism on the adapter axis and / or on the transverse axis. Thus, the joint can comprise an axis with a groove-like surface profile, and a spring-loaded rocker or a cone-shaped axis configuration with a return spring can lock the groove-like surface profile to define a defined rotational position that can only be changed by applying a higher torque. The torque is thus set for the axial rotation by the spring force of the rocker return spring. The stronger the spring force, the more frictional forces act on a locking ring and the locking receptacle and can be adjusted, for example, by prestressing the return spring, e.g. a preload screw. The torque for the transverse axis can be set using a screw connection in the luminaire base, e.g. with the help of disc springs or washers.

In a further advantageous development, the contact device can encompass a radial expansion or constriction area of the adapter element, the contact device preferably comprising a push button, a locking slide or a rocker for preferably spring-loaded securing of the encirclement and for providing a defined torque to prevent rotation of the adapter element. The luminaire base body is mechanically attached to the luminaire support structure and electrically contacted via the adapter element. In this development it is proposed that the contact device have a releasable locking mechanism, e.g. in the form of a push button, a rocker or a locking slide. The mechanical stability is provided by the clamping action of the spring-loaded securing of the rocker, slide or push button on the extension area of the adapter element, which is preferably designed as a double-conical locking ring, with increased friction between a conical surface of the locking ring and the conical receiving opening in the contact device forming an inhibiting torque . Thus, the electrical connector can only make electrical contact without absorbing mechanical forces.

A push button may include a spring for resetting the position of the push button. With this, the adapter element can snap into the contact device, the radial extension or constriction area of the adapter element being able to be positively gripped by the contact device or a receiving opening of the contact device. Thus, the adapter element is locked and centered independently in the contact device, so that the electrical and mechanical connection between the luminaire base body and the luminaire support structure is provided, but a stepless and arbitrary rotation about the axis of the adapter remains possible with the necessary stiffness. The adapter element can be released by pressing the push button, the spring being loaded. The adapter element is unlocked by the spring movement in that the larger opening of a keyhole-shaped recess is brought into position in front of the locking ring. When changing the luminaire body, a contact device-adapter element connection can thus be easily released without tools.

In addition, the contact device can comprise a locking slide, which can be wide or narrow. To insert the adapter element in the contact device, a return spring can be arranged on the locking slide so that the spring can be loaded by pushing the locking slide into an open position. The adapter element can hereby be inserted into or removed from the contact device.

Alternatively, it is possible that a rocker for spring-loaded securing of the wrap is included. If the adapter element is inserted into the contact device, the extension or constriction area of the adapter element can be gripped by the rocker, so that the adapter element can be locked and fastened in the contact device. By pressing the rocker. the adapter element can be released from the contact device, the rocker also remaining spring-loaded in the locking position. In a further advantageous development, the adapter element or the contact device can comprise a union nut or the like for connecting the adapter element to the contact device, an external thread being provided on an axially extending lateral surface of the contact device or the adapter element. The adapter element can comprise a union nut and the contact device can have an external thread, wherein a thread is provided on the axially extending lateral surface of the threaded bushing. The union nut is screwed onto the thread of the threaded bushing and tightened so that the adapter element can be attached to the outer surface of the contact device. Alternatively, it is conceivable that the contact device comprises a union nut, an external thread being provided on the outer surface of the adapter element. By means of a screw connection, the adapter element can be inserted into the contact device without tools or can be separated from the contact device, whereby a stable mechanical connection can be created in order to fasten the luminaire base body to the luminaire support structure. Nevertheless, a union nut and the external thread can also be understood as a screw-in thread or as a bayonet lock with a slot guide for locking pins.

In a further advantageous development, a light-scattering lighting attachment can be placed and fastened on the base body without tools. The lighting attachment can, for example, be attached and fastened to the base body or the housing of the base body by means of a screw or bayonet lock or by means of latching means, a ring with openings being provided on the housing, for example in the case of a bayonet lock. A connection between the lighting attachment and the luminaire base body can thus be released and / or restored by means of a simple translational relative movement between them. Furthermore, the lighting attachment can e.g. be cylindrical or spherical. The lighting attachment can be made of glass or transparent plastic, for example. With different designs and materials of the lighting attachment, radiation properties e.g. Color and direction of radiation of the luminaire body can be influenced. Furthermore, different lighting attachments can clearly determine the appearance of the lights and offer the possibility to add decorative features and to vary them.

In addition, diverse busbars with different cross sections are known from the prior art. These usually consist of an aluminum continuous casting profile, which is usually U or H-shaped. In many cases, a number of copper conductors are inserted into the inside of the profile, which conduct the current, and are contacted by an adapter element that can be freely positioned via contact pins or tongues. Various lights can be connected to this adapter element. These lights can be designed differently, both point lights, e.g. as a directed spotlight, as well as linear, diffuse radiant lights. In some cases, the luminaire is integrated directly into the adapter element.

These busbars have the disadvantage that linear lighting elements can only be used in relatively short sections and as a separate part. Furthermore, both parts of the luminaire - linear inserts and spotlights - cannot be combined at the same point, since only one adapter can sit in the rail at a time.

In a further advantageous development, the busbar can be a replaceable, preferably have translucent, that is to say at least partially translucent, or opaque, ie opaque cover, a light unit, in particular an LED light strip, preferably being arranged in the longitudinal direction in the busbar. If the light unit is arranged in the busbar, the cover can be transparent or semitransparent, so that light can shine through the cover. If no light unit is arranged, the cover can be opaque, in particular made of the same material as the remaining outer surface of the busbar, as a so-called blind cover. The LED light strip can be easily attached in the longitudinal direction. For this purpose, fastening holes can be provided in the edge area, for example, through which the LED light strip can be connected to the busbar using, for example, screws and corresponding nuts. The LED light strip can also be attached by gluing. It is also possible to establish the connection between the LED light strip and the busbar using snap-in connections.

Thus, the busbar itself serves as a linear light source and can be configured as a linear diffuse light source. This takes place through the choice of a translucent instead of an opaque cover and the use of an LED light strip, possibly through a luminescent insert, which can be arranged, for example, in or on a transparent cover. This enables a combination of a linear light unit and a spotlight to be achieved at the same point. The linear light unit can be indirect, e.g. be directed at the ceiling or wall, or directly illuminate an area to be illuminated, and the spotlight can define targeted light areas. In particular in the preferred case that the outer surface of the conductor rail is cross-sectionally symmetrical, for example round, elliptical, rectangular or square, so that by means of an adapter element a luminaire base body can be attached both hanging on the conductor rail below and sitting on the conductor rail above, any one Combination of the linear light rail and the spotlight of the luminaire body possible.

In a further advantageous development, the busbar can comprise at least two current conductors, which are preferably arranged radially opposite one another in or on the busbar, the busbar itself preferably being made of conductive material and providing a third current conductor. The busbar can advantageously have a round cross section, so that the radial orientation of the busbar does not cause any visual design change. At least two insulation profiles can be arranged in the busbar, each insulation profile at least partially comprising a current conductor, and the insulation profiles preferably being made of plastics. Each conductor is preferably designed to be accessible via a longitudinal slot or spaced openings in the surface of the conductor rail. Advantageously, the conductor rail itself can be designed as a third conductor, so that a three-pole electrical connection is made possible, for example for separately controlling a light unit integrated in the conductor rail and connected luminaire base bodies. In a further advantageous development, the busbar connection element can be designed in the form of a half-shell, an inner surface section of the busbar connection element being complementary to a jacket section of the busbar, and the busbar connection element can comprise at least two contact elements, in particular contact pins or contact tongues, which contact the current conductors of the busbar radially displaceably in the busbar connection element can. The busbar connection element is used to connect the main body of the luminaire to the busbar and has one or more adapter elements attached to it. The busbar connection element can advantageously be designed in the form of a half-shell in such a way that it can be placed, fastened and contacted on the busbar at least from two diagonally opposite sides. Furthermore, the busbar connection element can advantageously comprise at least two contact elements, in particular at least two metallic contact tongues, which are radially displaceable, so that by moving the contact elements, in particular the contact tongues, the busbar connection elements can make electrical contact with the current conductors in the busbar. Alternatively, the contact elements, in particular the contact tongues, can be held in plastic rails, which can be coupled radially by a user for mechanical connection and electrical contact to the conductor rail. The adapter element can be rigidly attached to the busbar connection element, or provide an additional pivot axis of the adapter element relative to the busbar connection element via a further joint. A round outer contour of the conductor rail enables an opposite and symmetrical arrangement of conductors, an external contact of the conductors being aesthetically advantageous since the contact points are less visible. This advantageously makes it possible to attach the busbar connecting element from two sides, from above and below. The symmetrical cross-sectional contour of the outer region of the busbar in particular enables a luminaire base body to be attached to the busbar both from below, that is to say hanging, and from above, that is to say sitting on the busbar. This can accomplish two things be: On the one hand, lighting of the areas below the conductor rail and lighting of the areas above the conductor rail can be achieved. On the other hand, the arrangement density of luminaire base bodies on the conductor rail can be increased, since adapter elements are conceivable that can provide both an downward and an upward-oriented adapter element.

In a further advantageous development, a busbar feed element for connection to an electrical feed line and for mechanical fastening of the busbar can be included, the busbar feed element being able to be pushed onto the busbar at an axial end side or inserted into the busbar. The busbar feed element is used to introduce electrical current from the building installation into the busbar and can e.g. hanging from a ceiling of a building. The busbar can have an internal profile, into which a fastening profile of the busbar feed element can be inserted in a form-fitting manner, and spring-loaded contact pins of the busbar feed element can contact the current conductors of the busbar on the end face. One or more further contact springs are preferably provided, which can contact a functional surface of the busbar, in particular a contact surface of a light unit of the busbar of the busbar, as a third, fourth or further conductor connection. For example, a spring comb of contact springs which are insulated from one another can transmit a plurality of signals between the busbar feed element and busbar, the signals preferably relating to information and actuating signals in parallel to the contact pins which relate to the energy supply, but also e.g. serve to supply power to a light strip of one or more busbars, so that light strips of a busbar assembly can also be addressed selectively. In this development, spring-loaded contact pins are advantageously provided, so that the contact pins can reliably make electrical contact with the current conductors in the conductor rail at the end. A multi-pole electrical connection for supplying the current is thus provided. Furthermore, one or more contact springs are advantageously provided, which can make electrical contact with the functional surface of the busbar, so that a return line or further supply of current to the current flowing through the current conductor can be achieved, and the spring action of the contact spring increases the stability of the mechanical connection. It is also advantageous that the busbar feed element has a fastening profile that is complementary to the inner profile of the busbar. As a result, the busbar feed element can be mechanically stably pushed or pushed onto the busbar at an axial end side. As a result, the busbar feed element can supply both the current conductors and an LED light strip with current. Furthermore, the busbar feed element can preferably allow an adjustable axial rotatability of the busbar, wherein an adjusting means can advantageously be provided. The axial rotational position of the busbar can thus be achieved via the busbar feed element, it being possible to adjust the rotatability by up to 180 ° via rotatably mounted parts of the busbar feed element. It is possible to determine the rotational position e.g. possible with a locking element such as a locking screw. This enables a further advantage, since a rotatability of the busbar feed element with the mechanical receiving parts of the busbar, in particular their inner profile together with the contact pins and contact spring, enables a freely adjustable alignment of the busbar. For example, a fixing screw can fix a setting position as the setting means. The axial rotary adjustment can be used on the one hand for light alignment, and on the other hand for weight compensation of the attached luminaire base.

In a further advantageous development, the light can be controlled via electrical contacts of the adapter element according to a fieldbus system and / or via a powerline system and / or via a radio system, preferably WLAN or Bluetooth standard. A fieldbus system such as KNX, InstaBUS, EIB or similar is used to pass on switching information from an intelligent home control system and can integrate the lighting system into a home network. Complex lighting control information such as DMX control information or DALI (Digital Addressable Lighting Interface) control information for varied lighting scenarios can also be transmitted via the bus system.

Control based on digital multiplexing via a two-wire line is advantageously made possible. For example, Powerline can be used for this as physical data transport technology over 2-wire. This is based on carrier frequency modulation of data signals, for example from the fieldbus system or a central radio receiver.

On the other hand, a wireless lighting control system such as HUE from Philips, Lightify from Osram or Casambi can also be used, and wireless lighting scenarios such as RGB color changes, dimming or the like can be provided on the basis of a WLAN-compatible lighting control system using a mobile device such as a smartphone or tablet. The one integrated in the luminaire base The control board can be equipped with the various physical transmission paths and logical control information and can be adapted by the software if necessary.
