Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a track lighting system.

TECHNICAL BACKGROUND

Track systems for luminaires offer the possibility of selectively positioning and / or aligning lighting means, e.g. according to the special needs of an illuminated room. Such a lighting system typically includes one or more busbars, each of which carries one or more lighting units and supplies them with electrical energy. The busbars thus serve, on the one hand, for power distribution and, on the other hand, as mechanical assembly means in order to fasten the lights at variable positions, in particular continuously, along a length extension of the respective rail. For this purpose, the rails can be mounted, for example, on a ceiling, a wall and / or another carrier. The luminaires themselves can be designed differently in terms of their lighting parameters, e.g. in terms of intensity, directional characteristics, beam angle, color, etc.

For receiving or fastening the lighting means, the rails of such systems include assembly slots, which typically have widths of 1 cm or more. In addition, track lighting systems generally have an electrical supply rail which is attached to a rear or inner end of the respective mounting slot for contacting the lighting means received. A minimum width for the respective assembly slot is to be selected to be correspondingly large in order to be able to guarantee the necessary minimum distances between the electrical contacts.

Once installed, such track lighting systems offer a high degree of flexibility in terms of the specific arrangement of the individual lights. For example, the lights can be displaceable along the rail and / or realigned relative to the rail. With typical track lighting systems, the Lights attached to the rail can also be removed, added and / or exchanged as required.

The pamphlets WO 2016/132361 A1 and WO 2018/037396 A1 describe examples of such track lighting systems.

SUMMARY OF THE INVENTION

One of the objects of the invention is to find solutions for track lighting systems which offer greater flexibility with regard to possible mounting points for the individual lights and thus the radiation characteristics of the system.

These and other objects are achieved by a track lighting system with the features of claim 1.

According to a first aspect of the invention, a track lighting system comprises two track half-shells, each on an inner side along a longitudinal extension with a first plug-in receptacle on a first mounting edge and a second plug-in receptacle on a second mounting edge and furthermore each with an electrical supply rail between the first plug-in receptacle and the second Plug receptacles are formed along the longitudinal extension; At least one half-shell connector for connecting the two rail half-shells to form a support rail that can be equipped on both sides, the half-shell connector being designed to be selectively insertable along the longitudinal extension for connecting the two rail half-shells facing each other on the inside into the opposing first plug-in receptacles or second plug-in receptacles When connecting the two rail half-shells to the half-shell connector, a first assembly slot is defined between the first assembly edges and a second assembly slot between the second assembly edges along the longitudinal extension of the rail half-shells; and at least one lamp adapter, which is designed to be selectively inserted along the longitudinal extension into the assembly slots such that the lamp adapter in an inserted state protrudes through the respective assembly slot between the supply rails and is in electrical contact with the supply rails.

One idea underlying the present invention is to build a support rail of a rail lighting system from two profile halves which are connected in such a way that adapters with lighting units can be introduced from different sides in order to produce different lighting with the same rail. For example, the track lighting system can be mounted on a room ceiling, one of the mounting slots being aligned in the direction of the ceiling and the other mounting slot in the direction of the floor. Lighting units installed in the upper mounting slot can thus be used for indirect lighting, while lighting units can emit direct light in the lower mounting slot.

A mounting rail according to the invention is not restricted to specific transverse profiles. For example, the rail half-shells can be designed with a rectangular transverse profile to form a rectangular support rail. In this case, an outside of the rail half-shells can be designed in particular flat. In another example, the rail half-shells can have a curved outer side, for example corresponding to a region of a cylinder jacket surface of a cylinder with a circular cross-section. By plugging together two half-cylinder-shaped rail half-shells, a mounting rail can be created, for example, which has approximately the outer contour of a circular cylinder, along whose outer surface on two opposite sides a mounting slot runs in the longitudinal direction.

Furthermore, the shape of the mounting slots or the shape of the support rail is not restricted along its length. The mounting rail can be straight or curved in the longitudinal direction. Furthermore, several such support rails can be combined with one another in order to create a more complex rail system.

Regardless of the specific shape of the mounting rail, the light adapter can be designed to be displaceable along the entire length of the mounting rail (at least insofar as none of the half-shell connectors is mounted on this side). For example, two or more half-shell connectors can be installed in one of the mounting slots. If a luminaire adapter is now inserted into the other mounting slot, it can be extended along the entire length the mounting rail can be moved within this mounting slot. When the lamp adapter is introduced into the assembly slot in which the half-shell connectors are mounted, however, it can only be moved between two of the half-shell connectors or between one of the half-shell connectors and a longitudinal end of the mounting rail.

The half-shell connector can, in particular, be fixed in its position after installation in the plug-in receptacles. The connection of the two rail half-shells via the half-shell connector can in particular (repeatedly) be designed to be detachable or non-detachable. The light adapter can not only be introduced into the mounting slots and designed to be displaceable in them. Furthermore, the fastening of the light adapter can be designed in such a way that the light adapter can also be pulled out of the mounting slots again, i.e. can be uninstalled.

The connection of the rail half-shells by means of the half-shell connector can in particular take place purely mechanically, e.g. via a form fit and / or force fit. As an alternative or in addition, further means can also be used for the connection closure. For example, the half-shell connector can be glued to the rail half-shells in an integral connection. In a further example, the half-shell connector can magnetically couple the two rail half-shells to one another. The person skilled in the art will find further corresponding solutions directly on the basis of the present disclosure and specialist knowledge.

Advantageous refinements and developments emerge from the further subclaims and from the description with reference to the figures.

According to a further development, the rail half-shells can each be designed symmetrically along a transverse extent which extends from the first mounting edge to the second mounting edge.

In particular, for example, the first plug-in receptacle can be designed mirror-symmetrically to the second plug-in receptacle in relation to the supply rail located therebetween. As a result, a Support rail result, the assembly slots of which together with the internal plug-in receptacles are formed identically on both sides of the support rail.

According to a further development, the rail half-shells can be designed identically.

In this further development, both rail half-shells can also be designed symmetrically around the transverse axis, which results in a particularly harmonious and practical mounting rail design in which both rail half-shells are interchangeable and both mounting slots and the adjacent plug-in receptacles are identical. The track lighting system is therefore uncomplicated and practical to assemble and use.

According to a further development, the half-shell connector can comprise two mutually displaceable clamping elements and an adjusting element, via which the clamping elements can be displaced relative to one another in such a way that the half-shell connector can be clamped in the plug-in receptacles for mutual fixation of the rail half-shells.

In a specific example, the adjusting element can, for example, have one or more screws or the like or be designed as such, wherein the screw or screws can connect the two clamping elements to one another in an adjustable manner. By turning the one or more screws, the two clamping elements can be pushed apart in order to achieve a clamping effect of the half-shell connector in an assembly space defined by the plug-in receptacles. Correspondingly, a reverse rotation of the screw (s) can press the two clamping elements together again, whereby the clamping effect is canceled and the half-shell connector can be removed from the assembly space of the plug-in receptacles.

Generally speaking, the adjustment element can thus serve either to press the two clamping elements apart in order to achieve a clamping effect in a mounting space formed by the plug-in receptacles, or to compress them in order to cancel a clamping effect of the half-shell connector.

According to a further development, at least one of the clamping elements can have joining arms which are designed to be complementary to joining areas of the plug-in receptacles.

In this way, in particular, a form-fitting clamping connection can be created between the two rail half-shells.

According to a further development, the joining arms can form a toothing with the respective joining areas of the plug-in receptacles in the clamped state.

Such a toothing and / or undercut can serve to support the clamping connection by holding at least one of the clamping elements via its joining arms in the respective joining areas of the plug-in receptacles. For example, the joining arms of one or both clamping elements in the clamped state can each form a (half-sided) dovetail connection with the associated joining areas of the plug-in receptacles. Overall, the connection between the rail half-shells and the half-shell connector can thus be improved.

According to a further development, the assembly slots can have a predetermined slot width of less than 7.5 mm.

In a specific example, the mounting slots can be about 6 mm wide or narrower. The light adapter can be designed to fit into an opening of 6 mm or less. In particular, the light adapter can thus have an insertion width of 6 mm or less. It goes without saying that the person skilled in the art can use other specific slot widths as long as the assembly slots and thus the rail profile remain sufficiently narrow, i.e. narrower than 7.5 mm. The track lighting system is thus characterized by a particularly narrow design. In contrast, conventional track lighting systems practically always have significantly wider mounting slots of 10 mm or more.

In addition, track lighting systems generally have an electrical supply rail, which is at a rear end of the respective Mounting slot for the light adapter is attached. Not least because a certain minimum distance is required between the electrical contacts (safety standards, etc.), this increases the minimum width of the mounting slot for the adapter. By attaching the supply rails to the sides of the adapter as in the present invention, the minimum slot width can be further reduced.

According to a further development, the lamp adapter can have latching elements by means of which the lamp adapter can be latched into the respective first plug-in receptacles and / or second plug-in receptacles in an inserted state.

For example, the locking elements can be designed on an outside of the light adapter in such a way that when the light adapter is plugged into one of the mounting slots, the locking elements are first pushed into the light adapter by the mounting edges of the rail half-shells and then jump out of the light adapter into the plug-in receptacles, whereby the light adapter in locks into place.

According to a further development, the lamp adapter can have a dismantling device which is designed to adjust the latching elements in order to release the latched lamp adapter from the mounting rail.

For example, the light adapter can be designed with one or more push buttons or the like. The locking arms can be adjusted by pressing the push buttons, e.g. retracted from an extended / unfolded locking position so that the light adapter can be pulled out of the mounting slot and thus removed from the mounting rail. For this purpose, the push button (s) can be provided on an outside of the light adapter in such a way that an operator can access them even when the light adapter is in the mounted, i.e. plugged in, state.

According to a further development, the light adapter can be designed to be displaceable along the respective mounting slot in the inserted state.

For example, the lamp adapter can have a sliding element or a sliding arm, along which the lamp adapter can slide along in a complementary recess in the respective rail half-shells. The light adapter can be held in the mounting rail by locking elements.

According to a further development, the light adapter in the inserted state can end flush with the respective mounting edges of the rail half-shells.

The luminaire adapter fits discreetly and space-savingly into the mounting rail design. For example, the light adapter can also be designed to hold one or more light units or light sources, which can be plugged into the mounted light adapter from outside the mounting slots, so that only the actual light sources are visible on the mounting rail, while the light adapter is more or less visible in the mounting slots remains less hidden.

According to a development, the electrical supply rails can be designed to supply the light adapter with electrical energy and / or with control signals in the plugged-in state.

The light adapter can have corresponding electronic components and / or parts which provide an electrical supply to the light adapter and the light units which are carried by it via the supply rail. For example, the light adapter can have a printed circuit board inside, which is supplied with electrical energy from the supply rail and controls the light units. Control signals can include, for example, signals from a digital addressable lighting interface (DALI) system. In particular, lamps carried by the lamp adapter can be controlled, e.g. with regard to a color, a radiation characteristic, a brightness, a lighting mode, etc.

The light adapter can have one or more electrical contacting elements which, when the light adapter is plugged in, establish electrical contact between the light adapter and the supply rail. For example, spring contacts and / or consumers on a Outside of the lamp adapter can be provided, via which electronic components inside the lamp adapter (for example a printed circuit board) can be electrically connected to the supply rail.

According to a further development, the electrical supply rails can each be plugged into a central plug-in receptacle of the respective rail half-shell between the first plug-in receptacle and the second plug-in receptacle.

The inside of the rail half-shell thus has a total of at least three recesses: the first plug-in receptacle (for receiving one or more half-shell connectors and / or one or more lamp adapters), the middle plug-in receptacle (for receiving the supply rail) and the second plug-in receptacle (again for receiving one or more light adapters) several half-shell connectors and / or one or more light adapters).

According to a further development, the rail half-shells can be made of a metal material and / or a plastic.

For example, rail half-shells can essentially be made of metal, a metal alloy and / or a metallic material combination, e.g. aluminum or an aluminum alloy. In this case, the resulting heat can be dissipated directly via the rail half-shells. As an alternative or in addition, the rail half-shells can also have a plastic material or be made from this.

According to one development, the light adapter can carry at least one light unit for generating light.

For example, the light adapter can be designed with one or more receptacles into which individual light units or lights can be inserted, e.g. an LED spotlight or another light source. The lighting unit can be electrically connected to the supply rail via the lighting adapter.

According to a development, the half-shell connector can terminate flush with the respective mounting edges of the rail half-shells after the two rail half-shells have been connected.

Like the luminaire adapter, the half-shell connector can also be discreetly embedded in the trunking to achieve an attractive and compact design.

According to a further development, the track light system can comprise at least two half-shell connectors, each of which is designed with a mounting element for suspended mounting of the track light system.

For example, the half-shell connectors can be mounted spatially offset to one another along the longitudinal extension of the support rail and thus serve on the one hand as connection points or sections of the two rail half-shells and on the other hand as assembly areas for suspending the track lighting system. In a specific example, two or more half-shell connectors can be mounted with a relative distance of about 1 m each. The relative distance and the total number of half-shell connectors can be selected accordingly in order to ensure sufficient mechanical stability of the mounted mounting rail.

In a specific example, the half-shell connector or connectors can have one or more openings for suspending the support rail.

The above configurations and developments can be combined with one another as desired, provided that it makes sense. Further possible configurations, developments and implementations of the invention also include combinations of features of the invention that are not explicitly mentioned above or below with regard to the exemplary embodiments. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Figure 1 shows a schematic sectional view of a track lighting system 100 according to an embodiment of the invention.

In this exemplary embodiment, the track lighting system 100 comprises two two identical track half-shells 2, which are each formed on an inner side 20 along a longitudinal extension L with a total of three cutouts. A first plug-in receptacle 5a is formed in each case on a first mounting edge 6a of the rail half-shells 2 along the longitudinal extension L (above in Fig. 1 ). In a transverse extent / transverse direction Q of the rail half-shell 2, a second plug-in receptacle 5b is formed on a second mounting edge 6b, the second plug-in receptacle 5b being designed mirror-symmetrically to the first plug-in receptacle 5a. In addition, there is a central plug-in receptacle 8 between the first plug-in receptacle 5a and the second plug receptacle 5b. Overall, the result is a symmetrical arrangement of the first and second plug-in receptacles 5a, 5b along the transverse extent Q between the first mounting edge 6a and the second mounting edge 6b.

The two rail half-shells 2 serve as housing shells or housing halves of a mounting rail 1 that can be equipped on both sides and can be made, for example, of aluminum or another material with good heat conduction. In the exemplary implementation of the Fig. 1 the rail half-shells 2 are formed with a curved outer side 18 which is shaped corresponding to a section of a cylinder surface of a circular cylinder. It goes without saying that this specific embodiment of the outside 18 is purely exemplary and the person skilled in the art can also use, for example, rectangular rail half-shells 2 with a flat (not curved) outside 18.

In the track lighting system 100, the first and second plug-in receptacles 5a, 5b serve on the one hand as assembly spaces for the introduction of half-shell connectors 3 to connect the two track half-shells 2 to the support rail 1, and on the other hand for the attachment of lamp adapters 4 to the support rail 1, as will be explained below .

The middle plug-in receptacle 8, on the other hand, serves as a receptacle for an electrical supply rail 7, which is designed to be plugged into the middle plug-in receptacle 8 and can supply the lighting means of the attached light adapter 4 with electrical energy and control signals via electrical contacts 14. For this purpose, the lamp adapters 4 can have electrical contacting elements 19, e.g. spring contacts, which establish the electrical contact 4 with the supply rail 7.

As already mentioned, the rail half-shells 2 are fixed to one another by one or more half-shell connectors 3 to form the support rail 1. Fig. 2 shows a perspective sectional view of such a half-shell connector 3 (cf. also Fig. 1 above). To connect the rail half-shells 2, the respective half-shell connector 3 is brought between the two rail half-shells 2 and inserted into the first plug-in receptacles 5a or second plug-in receptacles 5b. For this purpose, the two rail half-shells 2 are arranged facing one another on the inner sides 20, so that the first plug-in receptacles 5a and the second plug receptacles 5b are opposite one another. The half-shell connector 3 has a significantly shorter length than the rail half-shells 2 and can thus be inserted selectively along the longitudinal extension L in order to couple the two rail half-shells 2 to one another at different points or longitudinal sections. Fig. 3 shows an exemplary central arrangement of a half-shell connector 3 on a rail half-shell 2.

In this example, the half-shell connector 3 comprises two clamping elements 10a, 10b that can be pressed apart and one or more adjusting elements 11, via which the clamping elements 10a, 10b can be pressed apart in such a way that the half-shell connector 3 can be clamped in the plug-in receptacles 5a, 5b for mutual fixation of the rail half-shells 2.

For this purpose, the adjusting element 11 is designed as a screw. By turning the screw in a first direction of rotation, the clamping elements 10a, 10b can be pushed apart in an adjustment direction V. By corresponding rotation in a second direction of rotation opposite to the first direction of rotation, the clamping elements 10a, 10b are drawn together or pressed together again.

An upper clamping element 10a of the half-shell connector 3 has upper joining arms 12a which are designed to be complementary to upper joining areas 17a of the plug-in receptacles 5a, 5b. The upper joining arms 12a and the upper joining areas 17a have a stepped shape which is designed to form a form-fitting clamping connection and can serve as an assembly aid when adjusting the elements.

A lower clamping element 10b of the half-shell connector 3 has lower joining arms 12b which are designed to be complementary to lower joining areas 17a of the plug-in receptacles 5a, 5b. The lower joining arms 12b and the lower joining areas 17a also form a form-fitting connection after the clamping connection has been formed, the lower joining areas 17a having an undercut shape so that a toothing or half-sided dovetail connection is formed in a clamped state (cf. Fig. 1 above). This means that a form fit both in the transverse direction Q (ie in the vertical direction in Fig. 1 ) and perpendicular to the transverse direction Q (ie in the horizontal direction in Fig. 1 ) is formed.

By fixing the two rail half-shells 2 via one or more of the half-shell connectors 3, a first assembly slot 9a is defined between the first assembly edges 6a and a second assembly slot 9b between the second assembly edges 6b along the longitudinal extension L of the rail half-shells 2. In Fig. 1 concretely, an upper assembly slot 9a and an opposing lower assembly slot 9b are formed.

In order to create the narrowest possible rail profile, the assembly slots 9a, 9b can have a slot width B of less than 7.5 mm, e.g. 6 mm or less.

The half-shell connector 3 is designed in such a way that, after the two rail half-shells 2 have been connected, it ends flush with the respective mounting edges 6a 6b of the rail half-shells 2. After the mounting rail 1 has been mounted, a rail arrangement with an approximately circular cylindrical shape results, the cylinder having a mounting slot 9a, 9b in the longitudinal direction on two opposite sides, which is only interrupted at the mounting points of the half-shell connector 3.

As Fig. 1 and 3 can be removed, the track light system 100 further comprises one or more light adapters 4, which are designed to be selectively inserted along the longitudinal extension L into the mounting slots 9a, 9b in such a way that the respective light adapter 4 in an inserted state through the respective mounting slot 9a, 9b between the supply rails 7 protrudes and is in electrical contact with the supply rails 7. The light adapter 4 can be displaced along the longitudinal extension of the mounting rail 1 (see broad arrows in FIG Fig. 3 ). As already mentioned, the light adapter 4 is equipped with one or more light units 13, for example LED light elements. It goes without saying that the light adapter 4 is designed with corresponding electronic components in order to electrically couple the light units 13 to the supply rails 7 so that they can be supplied with electrical energy and with control signals.

For attachment to the mounting rail 1, the lamp adapter 4 is designed with a plurality of latching elements 15, via which the lamp adapter 4 in an inserted state in the respective first plug-in receptacles 5a and / or second plug receptacles 5b can be locked. In the example of the Fig. 1 the lamp adapter 4 can thus be inserted from below into the lower mounting slot 9b and brought between the supply rails 7, the latching elements 15 engaging in the lower plug-in receptacles 5b, whereby the lamp adapter 4 is held in the mounting rail 1. The light adapter 4 can be designed in such a way that, in the inserted state, it ends flush with the respective mounting edges 6a, 6b of the rail half-shells 2, so that only the light units 13 protrude from the support rail 1. In principle it is of course also possible for the lamp adapter 4 to protrude from the respective assembly slot 9a, 9b even after assembly. Furthermore, the lamp adapter 4 can be designed with a corresponding insertion width of 7.5 mm or less in order to fit into the mounting slots 9a, 9b.

For dismantling, the lamp adapter 4 can have a dismantling device 21, e.g. one or more push buttons, which can be designed to adjust the locking elements 15. For example, the dismantling device 21 can be designed to retract the latching elements into the lamp adapter 4 in order to release it from the latching and pull it out of the mounting slot 9a, 9b again and thus to dismantle it from the mounting rail.

The lamp adapter 4 can, for example, be plugged into the first (upper) assembly slot 9a for generating indirect light and into the second (lower) assembly slot 9b for generating direct light. Fig. 3 shows, for illustration, a track lighting system 100 with two lighting adapters 4, the lighting units 13 of which emit light in opposite directions. For example, the track lighting system 100 can be mounted with half-shell connectors 3, which are fixed at a certain distance from one another, for example 1 m, in the upper mounting slot 9a. The half-shell connectors 3 can be designed with assembly elements 16 for suspended assembly of the track lighting system 100, for example assembly openings from which the system 100 can be suspended (cf. Fig. 3 ).

One of the lamp adapters 4 can now be introduced into the upper assembly slot 9a and moved there, either between the two half-shell connectors 3 or between one of the half-shell connectors 3 and one end of the support rail 1 in the longitudinal direction. The other lamp adapter 4 can be adjusted in the lower assembly slot 9b over the entire longitudinal extent L of the support rail 1.

As a result, a track lighting system 100 is thus created which offers a high degree of flexibility in the arrangement and alignment of lighting units on a support rail 1 and at the same time is easy to assemble.
