Description

DESCRIPTION

Track lighting system

TECHNICAL FIELD OF THE INVENTION

[0001] The invention relates to a track lighting system.

TECHNICAL BACKGROUND

[0002] Luminaire track systems offer the possibility of selectively placing and/or aligning lighting equipment; for example, to achieve the special lighting that an illuminated space requires. These lighting systems typically include one or more busbars, each of which carries one or more lighting units and supplies electrical power to them. The bus bars therefore not only distribute power, but also serve as mechanical mounting means for fixing the lights in variable positions, in particular continuously, along a longitudinal extension of the respective rail. For this, the rails can be mounted; for example, on a ceiling, a wall and/or other support. The lights themselves can have different shapes in terms of their lighting parameters; for example, in terms of its intensity, directivity, beam angle, color, etc.

[0003] The rails of these systems include mounting slots, typically with a width of 1 cm or more, which are used to receive or hold the lighting means. Additionally, track lighting systems generally have a power supply rail, which is attached to the rear or inner end of the respective mounting slot to make contact with the housed light source. The minimum width selected for the respective mounting slot must be wide enough to ensure the minimum necessary distances between electrical contacts.

[0004] Once installed, track lighting systems offer a high level of flexibility in terms of the specific arrangement of the individual lights. For example, the lights can be designed to move along the rail and/or be repositioned relative to the rail. Additionally, in typical track lighting systems, lights connected to the track can be removed, added, and/or exchanged as needed.

[0005] WO 2016/132361 A1 and WO 2018/037396 A1 describe examples of such track lighting systems.

[0006] Publication EP 3321 569 A1 describes a low-profile suspension device for a modular lighting system, which has two half-rail housings, each with a power supply rail on an inner side, a half-rail connector -housing and a light adapter, which can be selectively inserted along a longitudinal extension into a top or bottom mounting slot.

SUMMARY OF THE INVENTION

[0007] One of the objects of the invention is to find solutions for track lighting systems that offer greater flexibility with respect to the possible mounting points of the individual lights and therefore the lighting characteristics of the system.

[0008] These and other objects are resolved by a track lighting system with the characteristics of claim 1.

[0009] According to a first aspect of the invention, a track lighting system has two track half-shells, each of which is formed on an inner side along a longitudinal extension with a first socket on a first mounting edge and a second socket on a second mounting edge and also each with a feed rail between the first socket and the second socket along the longitudinal extension; at least one half-shell connector for connecting the two rail half-shells and forming a mounting rail that can be fitted from both sides, wherein the half-shell connector for connecting the two internally facing rail half-shells for this The end is formed to be selectively inserted along the longitudinal extension into the first sockets or second sockets located opposite each other, where the connection of the two rail half-shells with the half-shell connector defines a first rail slot. mounting between the first mounting edges and a second mounting slot between the second mounting edges along the longitudinal extent of the rail half-shells; and at least one light adapter, which is formed to be selectively inserted along the longitudinal extension into the mounting slots such that the light adapter, when plugged in, protrudes through the respective mounting slot between the feed rails and is in electrical contact with the feed rails.

[0010] One of the ideas underlying the present invention is a mounting rail of a track lighting system constructed using two profile halves, which are connected in such a way that adapters with lighting units can be inserted from different sides. in order to generate different types of lighting with the same rail. For example, the track lighting system can be mounted on a ceiling, where one of the mounting slots faces the ceiling and the other mounting slot faces the floor. Lighting units installed in the top mounting slot can be used for indirect lighting, while lighting units in the bottom mounting slot can emit direct light.

[0011]A mounting rail, according to the invention, is not limited to specific cross profiles. For example, the rail half-shells may have a rectangular cross profile to form a rectangular mounting rail. In this case, one of the outer faces of the rail half-shells may in particular be flat. In another example, the rail half-shells may have a curved outer side; for example, corresponding to a surface of the jacket of a cylinder of circular section. By putting together two semi-cylindrical rail half-shells, a mounting rail can be created; for example, one having approximately the outer contour of a circular cylinder, along the outer surface of which a mounting groove runs in a longitudinal direction on two opposite sides.

[0012]Furthermore, the shape of the mounting slots or the shape of the mounting rail is not restricted along its longitudinal extent. The mounting rail can be straight or curved longitudinally. Additionally, several of these mounting rails can be combined to create a more complex rail system.

[0013]Regardless of the specific shape of the mounting rail, the light adapter may be formed to be movable along the entire longitudinal extent of the mounting rail (as long as none of the half-shell connectors are mounted on this side). For example, two or more half-shell connectors can be installed in one of the mounting slots. If a light adapter is now inserted into the other mounting slot, it can move within this mounting slot along the entire longitudinal extent of the mounting rail. When inserting the light adapter into the mounting slot in which the half-shell connectors are mounted, it can only move between two of the half-shell connectors or between one of the half-shell connectors and a longitudinal end of the mounting rail.

[0014]The half-shell connector can in particular be fixed in its position after installation in the sockets. The connection of the two rail half-shells via the half-shell connector can in particular be configured to be (repeatedly) detachable or non-detachable. Not only can the light adapter be inserted into the mounting slots and moved within them, but the fixing of the light adapter can also be carried out in such a way that the light adapter can be removed from the mounting slots; that is, it can be uninstalled.

[0015]In particular, the half-shells can be connected by the half-shell connector using mechanical means only; for example, with a positive and/or non-positive connection. Alternatively or additionally, additional means may also be used for connection closure. For example, the half-shell connector can be glued to the rail half-shells to form a material bond. In a further example, the half-shell connector may magnetically connect the two rail half-shells together. Other corresponding solutions will be immediately apparent to the person skilled in the art based on the present disclosure and specialized knowledge.

[0016] Advantageous embodiments and developments are described in the additional dependent claims and the description with reference to the figures.

[0017]According to a development, the rail half-shells may be formed symmetrically along a transverse extension extending from the first mounting edge to the second mounting edge.

[0018]In particular, for example, the first socket may be formed symmetrically to the second socket in relation to the power rail located between them. The result is a mounting rail with mounting slots and internal sockets of identical design formed on both sides of the mounting rail.

[0019]According to a later development, the rail half-shells can be formed identically.

[0020]In this development, both rail half-shells can also be formed symmetrically around the transverse axis, resulting in a particularly harmonious and practical mounting rail design where both rail half-shells are interchangeable and both slots of mounting, along with adjacent sockets, are identical. The track lighting system is therefore simple and practical to install and use.

[0021]According to another development, the half-shell connector may comprise two mutually displaceable fastening elements and an adjusting element, which can be used to move the fastening elements relative to each other such that the half-shell connector Housing can be clamped in sockets for mutual fixation of rail half-housings.

[0022]In a specific example, the adjusting element may have one or more screws or the like, or be formed so that the screw or screws can connect the two fastening elements together in an adjustable manner. By turning one or more screws, the two fastening elements can be separated to achieve a clamping effect of the hemispherical connector in a mounting space defined by the sockets. Correspondingly, a reverse rotation of the screw or screws can press the two fastening elements against each other again, as a result of which the clamping effect is nullified and the half-shell connector can be removed from the mounting space of the sockets. .

[0023] Generally speaking, the adjusting element can serve to separate the two fastening elements in order to achieve a clamping effect in a mounting space formed by the sockets, or to press them together in order to nullify an effect. semi-shell connector fastening.

[0024] According to another development, at least one of the fastening elements has connecting arms that are formed to complement the connecting areas of the sockets.

[0025] In this way, a form-fitting latching connection can be created between the two rail half-shells.

[0026] According to a development, the connecting arms can interlock with the respective connecting areas of the sockets in the clamped state.

[0027] An interlock and/or a recess of this type can serve to support the latch connection, holding at least one of the clamping elements with their connecting arms in the respective joining areas of the sockets. For example, the connecting arms of one or both fasteners in the clamped state may each form a dovetail (half-sided) connection with the associated connecting areas of the sockets. In general, the connection between the rail half-shells and the half-shell connector can be improved.

[0028] According to a development, the mounting slots may have a predetermined slot width of less than 7.5 mm.

[0029] In a specific example, the mounting slot should be approximately 6 mm wide or narrower. The light adapter can be shaped to fit an opening of 6mm or less. In particular, the light adapter may therefore have an insertion width of 6 mm or less. Needless to say, other specific slot widths may be used by one skilled in the art as long as the mounting slot, and therefore the rail profile, remain sufficiently narrow; that is, with widths less than 7.5 mm. The track lighting system is characterized by a particularly narrow design. In contrast, conventional track lighting systems almost always have significantly wider mounting slots of 10 mm or more.

[0030] Additionally, track lighting systems typically include a power supply rail attached to a rear end of the respective light adapter mounting slot. An additional problem is that a certain minimum distance is required between electrical contacts (safety regulations, etc.), which increases the minimum width of the mounting slot for the adapter. The minimum slot width can be further reduced by attaching the present feed rails to the sides of the adapter as in the present invention.

[0031] According to one embodiment, the light adapter may have latching elements that can be used to latch the light adapter into the respective sockets and/or second sockets when plugged in.

[0032] For example, the latching elements may be formed on an outer side of the light adapter such that when the light adapter is inserted into one of the mounting slots, the latching elements are first pressed into the adapter. of light through the mounting edges of the rail half-housings and pop out of the light adapter into the sockets, thereby snapping the light adapter into place.

[0033] According to a further development, the light adapter may have a disassembly device which is formed to adjust the latching elements in order to release the latched light adapter from the mounting rail.

[0034] For example, the light adapter may be formed with one or more push buttons or the like. The locking arms can be adjusted by pressing the push buttons; e.g., they can be retracted from an extended/deployed locking position so that the light adapter can be pulled out of the mounting slot and removed from the mounting rail. To this end, the push button(s) may be provided on an outer side of the light adapter in such a way that an operator can access them, even when the light adapter is mounted, i.e. inserted.

[0035] According to another development, the light adapter may be formed to be movable in the plugged-in state along the respective mounting slot.

[0036] For example, the light adapter may have a sliding member or a sliding arm, along which the light adapter may slide into a complementary recess in the respective rail half-housings. The light adapter can be held on the mounting rail using clip-on elements.

[0037] According to a later development, the light adapter may sit flush with the mounting edges of the rail half-shells when inserted.

[0038] The light adapter then fits discreetly and space-savingly into the mounting rail design. For example, the light adapter may also be formed to hold one or more lighting units or lighting means that can be inserted into the mounted light adapter from the outside of the mounting slot, so that only the lighting means actuals are visible on the mounting rail, while the light adapter is more or less hidden in the mounting slots.

[0039] According to a further development, the power supply rails may be formed to supply power and/or control signals to the light adapter when it is plugged in.

[0040] The light adapter may have corresponding electronic parts and/or components that provide electrical power for the light adapter and the lamp units carried by it on the power rail. For example, the light adapter may include within it a printed circuit board to which electrical power is supplied from the power rail and which controls the lighting units. The control signals may include signals from a digital addressable lighting interface (DALI) system, for example. In particular, color, lighting characteristics, brightness, lighting mode, etc. can be controlled. of the lighting media carried by the light adapter.

[0041] The light adapter may have one or more electrical contact elements that, when the light adapter is plugged in, establish electrical contact between the light adapter and the power rail. For example, spring contacts and/or collectors may be provided on an outer side of the light adapter, with which electronic components inside the light adapter (e.g., a printed circuit board) can be electrically connected to the rail. of feeding.

[0042] According to another development, each of the power supply rails can be plugged into a central socket of the respective rail half-shell, between the first socket and the second socket.

[0043] Therefore, the interior of the rail half-shell has at least three recesses: the first recess (to accommodate one or more half-shell connectors and/or one or more light adapters), the central recess (to accommodate the power rail) and the second recess (again to accommodate one or more half-shell connectors and/or one or more light adapters).

[0044] According to a further development, the rail half-shells may be made of a metal and/or plastic material.

[0045] For example, the rail half-shells may be made essentially of metal, a metal alloy and/or a combination of metal materials; for example, aluminum or an aluminum alloy. In this case, the resulting heat can be dissipated directly through the rail half-shells. Alternatively or additionally, the rail half-shells may also have or be made of a plastic material.

[0046] According to a further development, the light adapter has at least one lighting unit for generating light.

[0047] For example, the light adapter may be formed with one or more receptacles into which lighting units or individual lights may be plugged. for example, an LED spotlight or other means of lighting. In this case, the lighting unit can be electrically connected to the power rail through the light adapter.

[0048] According to a further development, the half-shell connector is configured in such a way that, after joining the two rail half-shells, it is flush with the respective mounting edges of the rail half-shells.

[0049] As with the light adapter, the half-shell connectors can be discreetly embedded into the mounting rail for an attractive and compact design.

[0050] According to one embodiment, the track lighting system may include at least two half-shell connectors, each of which is formed with a mounting element for suspended mounting of the track lighting system.

[0051]For example, the connectors of the half-shells may be mounted such that they are spatially offset from each other along the longitudinal extent of the mounting rail and therefore serve as connecting points or sections of the two track semi-housings and as mounting areas for the suspension of the track lighting system. In a specific example, two or more half-shell connectors may be mounted with a relative distance of approximately 1 m each. In this case, the relative distance and total number of half-shell connectors can be selected accordingly to ensure sufficient mechanical stability of the assembled mounting rail.

[0052]In a specific example, the half-shell connector(s) may have one or more openings for mounting rail suspension.

[0053]The embodiments and updated versions described above may be combined in any way where appropriate. Other possible embodiments, updated versions and implementations of the invention also include combinations of features of the invention described above or below with respect to exemplary embodiments that are not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects to the respective basic form of the present invention as improvements or additions. BRIEF DESCRIPTION OF THE FIGURES

[0057]Figure 1 is a schematic sectional view of the track lighting system 100 according to an embodiment of the invention.

[0058]In this exemplary embodiment, the track lighting system 100 comprises two identical track half-shells 2, each of which is formed by a total of three recesses on an inner side 20 along a longitudinal extension L. On a first mounting edge 6a of the rail half-shells 2 along the longitudinal extension L a first socket 5a is formed (top in Figure 1). A second socket 5b is formed on a second opposite mounting edge 6b in a transverse extension/transverse direction Q of the rail half-shell 2, where the second socket 5b is formed symmetrically to the first socket 5a. Furthermore, a middle socket 8 is also formed between the first socket 5a and the second socket 5b. The general result is a symmetrical arrangement of the first and second sockets 5a, 5b along the transverse extension Q between the first mounting edge 6a and the second mounting edge 6b.

[0059]The two rail half-shells 2 serve as housing shells or housing halves of a mounting rail 1 which can be loaded from two sides and can be made, for example, of aluminum or another material with good thermal conduction . In the exemplary embodiment of Figure 1, the rail half-shells 2 are formed with a curved outer side 18 that is shaped to fit with a section of a cylindrical surface of a circular cylinder. Needless to say, this specific design of the outer side 18 is purely illustrative and one skilled in the art could also use rectangular rail half-shells 2 with a flat (not curved) outer side 18, for example.

[0060]In the track lighting system 100, the first and second sockets 5a, 5b serve as mounting spaces for the introduction of half-shell connectors 3 for connecting the two track half-shells 2 to the mounting rail 1 and are also used to attach light adapters 4 to mounting rail 1 as explained below.

[0061]The central socket 8, on the other hand, serves as a socket for a power supply rail 7, which is shaped to be pluggable into the central socket 8 and can supply the lighting means of the connected light adapter 4 with power electrical and control signals through electrical contacts 14. For this purpose, the light adapter 4 may have electrical contact elements 19; for example, spring contacts, which make electrical contact 14 with the power rail 7.

[0062]As already mentioned, the rail half-shells 2 are fixed together by one or more half-shell connectors 3 to form the mounting rail 1. Figure 2 shows a perspective sectional view of said connector of half-shell 3 (see also Figure 1 above). To connect the rail half-shells 2, the respective half-shell connector 3 is placed between the two rail half-shells 2 and inserted into the first sockets 5a or second sockets 5b. For this purpose, the two rail half-shells 2 are arranged facing each other on the inner sides 20, so that the first sockets 5a and the second sockets 5b are opposite each other. The half-shell connector 3 is significantly shorter in length than the rail half-shells 2 and can therefore be selectively inserted along the longitudinal extension L to connect the two rail half-shells 2 to each other in different points or in different longitudinal sections. Figure 3 shows an example of a central arrangement of a half-shell connector 3 in a rail half-shell 2.

[0063]In this example, the half-shell connector 3 comprises two latching elements 10a, 10b that can be separated and one or more adjustment elements 11 that can be used to separate the latching elements 10a, 10b such that the half-shell connector 3 can snap into sockets 5a, 5b to hold both rail half-shells 2.

[0064]For this purpose, the adjusting element 11 is formed as a screw. By turning the screw in one direction of rotation, the clamping elements 10a, 10b can be separated in an adjustment direction V. By turning the screw in the direction of rotation opposite to the first, the hooking elements 10a, 10b are brought together or pressed together new.

[0065]An upper fastening member 10a of the half-shell connector 3 has upper joining arms 12a, which are formed to complement the upper joining areas 17a of the sockets 5a, 5b. The upper link arms 12a and the upper link areas 17a have a stepped shape, which is formed as a positive-fit latch connection and can serve as a mounting aid when fitting the elements.

[0066]A lower fastening member 10b of the half-shell connector 3 has lower joining arms 12b, which are formed to complement the lower joining areas 17a of the sockets 5a, 5b. The lower connecting arms 12b and the lower connecting areas 17a also create a positive fit connection after the clamping connection has been formed, in which the lower connecting areas 17a have a recessed shape, so that in state clamping, a toothed or dovetail connection is formed on one side (see Figure 1 above). This means that a positive fit is created both in the Q transverse direction (i.e., in the vertical direction in Figure 1) and perpendicular to the Q transverse direction (i.e., in the horizontal direction in Figure 1).

[0067]The fixing of the two rail half-shells 2 by using one or more half-car house connectors 3 defines a first mounting groove 9a between the first mounting edges 6a and a second mounting groove 9b between the second mounting edges 6b along the longitudinal extension L of the rail half-shells 2. An upper mounting slot 9a and an opposite lower mounting slot 9b are specifically shown in Figure 1.

[0068]In order to create a rail profile that is as narrow as possible, the mounting slots 9a, 9b can have a slot width B of less than 7.5 mm; for example, 6 mm or less.

[0069]The half-shell connector 3 is formed in such a way that, after the two rail half-shells 2 have been connected, it is flush with the respective mounting edges 6a 6b of the rail half-shells 2 After mounting the mounting rail 1, the result is a rail arrangement with an approximately circular-cylindrical shape, where the cylinder has a mounting groove 9a, 9b in the longitudinal direction on two opposite sides, which is only interrupted. at the half-shell connector mounting points 3.

[0070]As can be seen in Figures 1 and 3, the rail lighting system 100 therefore also comprises at least one light adapter 4, which is formed to be selectively insertable along the longitudinal extension L into the mounting slots 9a, 9b such that the light adapter 4 protrudes through the respective mounting slot 9a, 9b between the power rails 7 when plugged in and is in electrical contact with the power rails 7 The light adapter 4 can be moved along the longitudinal extension of the mounting rail 1 (see wide arrows in Figure 3). As already mentioned, the light adapter 4 is equipped with one or more lighting units 13; for example, LED light elements. Naturally, the lighting adapter 4 is formed by corresponding electronic components to electrically connect the lighting units 13 to the power rails 7, so that they can receive electrical power and control signals.

[0071]For attachment to the mounting rail 1, the light adapter 4 is formed with a plurality of hooking elements 15, which can be used to hook the light adapter 4 to the first sockets 5a and/or second sockets 5b respective when in a plugged-in state. In the example of Figure 1, the light adapter 4 can therefore be inserted from below into the lower mounting slot 9b and placed between the feed rails 7, in which the latching elements 15 engage in the lower sockets 5b, as a result of which the light adapter 4 is held in the mounting rail 1. The light adapter 4 can be formed in such a way that when plugged in, it is flush with the respective mounting edges 6a, 6b of the rail half-housings 2, so that only the lighting units 13 protrude from the mounting rail 1. In principle, it is of course also possible that the light adapter 4 still protrudes from the respective mounting slot 9a, 9b after assembly. Furthermore, the light adapter 4 can be formed with a corresponding insertion width of 7.5 mm or less, in order to fit into the mounting slots 9a, 9b.

[0072]For disassembly, the light adapter 4 may have a disassembly device 21; for example, one or more push buttons, which can be formed to adjust the latching elements15. For example, the disassembly device 21 can be shaped to retract the latching elements on the light adapter 4 to release the latter from the latch and remove it from the mounting slot 9a, 9b and, therefore, remove it from the mounting rail.

[0073]The light adapter 4 can be inserted, for example, into the first (upper) mounting slot 9a to generate indirect light and into the second (lower) mounting slot 9b to generate direct light. By way of illustration, Figure 3 shows a track lighting system 100 with two light adapters 4 whose lighting units 13 emit light in opposite directions. For example, the track lighting system 100 can be mounted with half-shell connectors 3, which are fixed in the upper mounting slot 9a at a certain distance from each other; for example, at a distance of 1 m. The half-shell connectors 3 may be formed by mounting elements 16 for suspended mounting of the track lighting system 100; for example, mounting openings in which the system 100 can be hung (see Figure 3).

[0074]A light adapter 4 can now be inserted into the upper mounting 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 rail assembly 1 in longitudinal direction. The other light adapter 4 can be fitted into the lower mounting slot 9b over the entire longitudinal extension L of the mounting rail 1.

[0075]The result is a track lighting system 100 that offers a high level of flexibility in terms of the arrangement and alignment of lighting units on a mounting rail 1 and is also easy to install.

[0076]In the detailed description above, several features have been grouped into one or more examples to improve the rigor of the presentation. However, it should be understood that the above description is merely illustrative and is in no way restrictive.
