Description

AREA OF INVENTION

The use of track lighting, for example in buildings, is well-known. Furthermore, systems have already been proposed in which electrical conductors are integrated into a track profile to provide a supply voltage and control signals. Such track systems include, for example, a number of different types of light inserts, such as spotlights or linear light inserts, which can also be combined.

Furthermore, for example in the EP 3 336 420 B1 A lighting system is described that includes a channel for accommodating a lighting unit that can be inserted into it. A connector is provided for insertion into the channel to electrically couple sections of the power rail. With the lighting system of EP 3 336 420 B1 For example, a slim design and the creation of aesthetically pleasing light strips with a small installation depth and width should be achieved.

Furthermore, in the DE 20 2014 100 258 U1 A lighting system with a first and a second luminaire is described. The first luminaire has a first light source and a control gear, preferably a converter or ballast. The second luminaire has a second light source. DE 20 2014 100 258 U1 This describes how the first and second light sources are detachably connected via an electrical connection. The control gear serves to operate the first and second light sources. DE 20 2014 100 258 U1 describes that the first light fixture has a current tap element to conduct current from a mounting rail to the control gear.

Controllability of the luminous components in lighting systems is frequently desired nowadays, for example in the form of dimming. However, the electrical and electronic components required to implement this controllability are often expensive and increase the cost of the lighting systems.

SUMMARY OF THE INVENTION

Against this background, the invention is based on the objective of providing an improved lighting arrangement with a rail that enables a modular design, can be manufactured at reduced costs and at the same time allows for good controllability of luminous components.

According to the invention, this problem is solved by a lighting arrangement having the features of claim 1.

A lighting arrangement is proposed, comprising a first lighting module and a second lighting module, and a rail designed for coupling and/or at least partially accommodating the first and second lighting modules. A conductor system for supplying electrical current and a control signal is provided along the rail.

The first lighting module is configured to be coupled to the conductor assembly in order to receive electrical current for its power supply and the control signal from the conductor assembly. Furthermore, the first lighting module is configured to process the control signal, in particular to interpret it, and to control the first lighting module depending on the control signal.

The first and second lighting modules are designed to be coupled together in such a way that a signal for controlling the second lighting module can be transmitted from the first lighting module to the second lighting module.

One of the underlying concepts of the invention is that a lighting arrangement with a track and lighting modules can be created in this way, where not all lighting modules need to be equipped with relatively expensive devices for processing a control signal, particularly for interpreting it. Advantageously, for example, the second lighting module can be manufactured more cost-effectively, since comparatively expensive electronic components can be omitted. At the same time, a modular design of the lighting arrangement and good controllability are enabled. Optionally, the second lighting module can be configured to be coupled with a third lighting module in such a way that the control signal can be transmitted to the third lighting module, which can, for example, be designed in the same way as the second lighting module.

Advantageous embodiments and further developments of the invention will become apparent from the further dependent claims and from the description with reference to the figures.

In one embodiment, the second lighting module can be controlled together with the first lighting module according to a master-slave principle, whereby the second lighting module, as a slave, is subordinate to the first lighting module, which is the master. Controlling the second lighting module can thus be implemented in a simple manner.

In this advanced development, the first lighting module features an electronic arrangement that processes, and in particular interprets, the control signal received from the conductor assembly, and allows the first lighting module to be controlled based on this signal. Specifically, the electronic arrangement enables the signal to be transmitted to the second lighting module. This eliminates the need for one or more complex and expensive electronic components on the second lighting module and/or reduces the complexity of the electronic arrangement on the second lighting module.

In the invention, the second lighting module is designed to be coupled to the conductor assembly in order to supply electrical energy to the second module. The lighting module can be mounted on the ladder assembly. The ladder assembly can therefore also be used to supply power to the second lighting module.

In the invention, the first lighting module has a first contact device by means of which the operating current supply conductors of the conductor assembly can each be electrically connected. Furthermore, in the invention, the first lighting module has a second contact device by means of which the control signal supply conductors of the conductor assembly can each be electrically connected.

In one embodiment, the control signal provided at the conductor assembly, particularly at the control signal supply conductors, can be a DALI signal. However, the use of other control methods or alternative dimming methods is also conceivable in other embodiments.

In the invention, the second lighting module has a third contact device by means of which the operating current supply conductors of the conductor assembly can each be electrically connected. Thus, the second lighting module can use the operating current supply conductors for power supply by directly coupling them, while, according to the invention, the signal for controlling the second lighting module is provided by the first lighting module.

According to one embodiment, the first and second lighting modules each have a printed circuit board (PCB), and the contact elements of the contact devices are arranged elastically on the PCB, with each contact element located in a corresponding recess in an edge of the PCB. In particular, the contact elements may protrude from the outside of the lighting module through openings in a housing component on one or both longitudinal sides. This allows the contact devices to be arranged in a space-saving manner, and also enables the supply voltage and the control signal to reach their intended destinations—where they are used, processed, interpreted, or converted—without unnecessary detours. Furthermore, this arrangement ensures reliable contact between the conductors.

According to the invention, the conductor assembly comprises at least two operating current supply conductors and two control signal supply conductors, wherein, in a further development, it can be provided in particular that the operating current supply conductors and control signal supply conductors are arranged symmetrically with respect to a longitudinal center plane of the rail. This can, for example, simplify the design and arrangement of the contact devices and the housing components.

According to a further training, the first and second lighting modules are each designed as a lighting insert. Furthermore, this training stipulates that the conductor assembly is located inside the track and that the lighting inserts can be placed inside the track.

In one embodiment, when the lighting modules are in use, the conductor assembly is arranged laterally to the lighting modules, in particular on both sides of the lighting modules. This contributes to a space-saving design.

In one embodiment, the contact elements of each contact device are arranged symmetrically on both longitudinal sides of the light module. This can also contribute to simplifying the manufacturing of the light modules.

In the invention, the first lighting module and the second lighting module are each equipped with at least one connecting device, wherein the connecting devices of the first and the second lighting module are configured to correspond to each other and the second lighting module can be connected to the first lighting module by means of the connecting devices for the transmission of the signal for controlling the same.

In one embodiment, the connecting devices are arranged at one end face of the first or second lighting module. This is particularly advantageous for slim, elongated, and elegant lighting modules that require minimal space and are to be housed and coupled, for example, in a rail.

In a further training course, the connection devices are designed as plug-in connectors, for example, a male and a corresponding female connector. This allows for a simple and reliable connection of the lighting modules. For example, it can be provided that the lighting modules, when coupled to and/or mounted in the rail, can be connected using the connection device in such a way that the lighting modules are slid towards each other. Plug-in connectors, for example, are well suited for this purpose.

In one embodiment, the connecting elements of the first and second lighting modules are each arranged on the circuit board. This avoids detours when connecting the two lighting modules, and also contributes to space savings and efficient manufacturability.

In one embodiment, the first and second lighting modules can be inserted into the interior of the rail from the lower side of the rail in a standard mounting state, whereby in this embodiment the mounting of the rail can, for example, be along a ceiling.

In one embodiment, the first and second lighting modules are each elongated, preferably slim. Such lighting modules can be advantageously used, for example, to create aesthetically pleasing and narrow, modularly constructed light strips.

In this advanced training course, the first and second lighting modules are each designed linearly. However, other configurations are also conceivable.

In particular, the rail is designed as a low-voltage rail.

In one embodiment, the first and second lighting modules are each designed using a chip-on-board process with one or more strip-shaped lighting devices. This is particularly relevant in the design of the rail and the lighting modules, for example, in the form of... For lighting inserts with small dimensions and spacing, the use of strip-shaped lighting devices, such as LEDs, in the chip-on-board ("COB") method can be advantageous in helping to avoid visible light points and ensure uniform light emission and aesthetic effect.

In a training course, the lighting arrangement can include several first lighting modules and/or several second lighting modules.

In a further embodiment, the lighting arrangement has several second lighting modules, which are each directly or indirectly coupled to the first lighting module in such a way that the signal for controlling the second lighting modules can be transmitted from the first lighting module to the second lighting modules.

In a further embodiment, the lighting arrangement can have more than one first lighting module, wherein at least one of the first lighting modules is coupled to at least one second lighting module for transmitting the signal for controlling the second lighting module from the first lighting module to the second lighting module. In particular, a further embodiment can provide a plurality of first lighting modules, each of which can be coupled to at least one second lighting module.

The above embodiments and further developments can be combined with one another as appropriate. Further possible embodiments, further developments, and implementations of the invention also include combinations of features of the invention described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. 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.

DESCRIPTION OF EXAMPLES OF EXECUTION

A lighting arrangement 100 according to an embodiment of the invention is described below with reference to the Figs. 1-8 described.

The lighting arrangement 100 comprises two linear, slim, and elongated lighting modules 102 and 112, respectively, and a rail 9, which is specifically designed as a low-voltage rail. The lighting modules 102 and 112 are each designed as a lighting insert for insertion into an inner area 125 of the rail 109, wherein the lighting modules 102 and 112 are received in the inner area 125 of the rail 109 and coupled to the rail 109.

In particular, the lighting arrangement 100 can, in its various versions, comprise more than one second lighting module 112 in addition to the first lighting module 102. For example, along a longitudinal extension L of the rail 109, two second lighting modules 112 can be arranged adjacent to one another following a first lighting module 102. An even larger number of second lighting modules 112 associated with the first lighting module 102 is also conceivable.

The lighting arrangement 100 can be designed in particular as a slim and aesthetically pleasing, modularly constructed light strip.

The light modules 102, 112 can be inserted into the rail 109 from an open side of the rail 109 in a direction perpendicular to the longitudinal direction L.

The track 109 can, for example, be mounted along the ceiling of a room. In this mounting configuration, the lighting modules 102 and 112 can be accessed from the underside of the track 109, corresponding to a visible side S (see figure). Fig. 1 , 7, 8 , into which they are used.

Rail 109, see Fig. 7, 8 , is formed in cross-section with an essentially inverted U-shaped profile symmetrical to a longitudinal center plane M of the rail 109 with a web, flanges and an inner area 125.

A conductor assembly 126 is arranged along the rail 109 in the interior space 125. The conductor assembly 126 is formed in two parts, with two base bodies 126c arranged laterally in the interior space 125 and a total of two operating current supply conductors 126a and two control signal supply conductors 126b. The conductors 126a and 126b are arranged symmetrically with respect to the longitudinal center plane M, with each base body 126c containing one operating current supply conductor 126a and one control signal supply conductor 126b. The conductor assembly 126 thus enables the supply of electrical current and a control signal. The operating current supply conductors 126a are designed for supplying a low electrical voltage, for example, < 60 volts.

For example, a DALI signal or alternatively a signal based on another protocol or control method, such as another dimming method, can be provided on the control signal supply conductors 126b.

When the light modules 102, 112 are inserted into the rail 109, the conductor assembly 126 is arranged in a space-saving manner on either side of the light modules 102, 112, see Figs. 7 and 8 .

The first light module 102 has an elongated housing component 20, an elongated circuit board 21 and an elongated cover 50.

The second light module 112 has an elongated housing component 120, an elongated circuit board 121 and an elongated cover 150.

The housing components 20, 120 are each box-shaped with an open top, are each, for example, completely or at least partially translucent, and are designed to accommodate the circuit board 21 or 121. After the circuit board 21, 121 has been installed, the housing components 20, 120 can be closed by means of the respective associated cover 50, 150 to form the light modules 102, 112.

The first light module 102 has a first end face 102a and a second end face 102b. The second light module 112 has a first end face 112a and a second end face 112b. In Fig. 1 The first end 102a of the first light module 102 and the second end 112b of the second light module 112 are adjacent to each other after the modules 102, 112 have been inserted.

For the mechanical fastening of the light modules 102, 112, the housing components 20, 120 have elastically spring-loaded clip elements 129 on their longitudinal sides, some of which are adjacent to the ends 102a,b and 112a,b of the light modules 102, 112 respectively, others are arranged, for example, along the longitudinal extent of each of the modules 102, 112 approximately in the middle of the same.

Adjacent to the second end 102b, the first light module 102 has a first contact device 30. The contact device 30 is formed with two contact elements 130 arranged symmetrically on both longitudinal sides of the light module 102, the contact elements 130 being configured to electrically contact each of the operating current supply conductors 126a. The contact elements 130 are formed with spring-loaded sections, each of which is attached to the circuit board 21, see Figure 1. Fig. 5 The contact elements 130 are each partially arranged in the area of a recess 24a in the edge of the circuit board 21 and can spring elastically into the recess 24a.

In the longitudinal walls of the housing component 20, this has opposing openings 110, through which, after assembly of the light module 102, one of the elements 130 protrudes from an outer side of the light module 102.

Adjacent to the first end 102a, the first lighting module 102 has a second contact device 31. The contact device 31 is formed with two contact elements 131 arranged symmetrically on both longitudinal sides of the lighting module 102, the contact elements 131 being configured to electrically contact each of the control signal supply conductors 126b. The contact elements 131 are designed with partially resilient sections, each of which is attached to the circuit board 21, see Figure 1. Fig. 6 The contact elements 131 are each partially arranged in the area of a recess 24b in the edge of the circuit board 21 and can spring elastically into the recess 24b.

In the longitudinal walls of the housing component 20, this has opposing openings 10 through which, after assembly of the light module 102, one of the elements 131 protrudes from an outer side of the light module 102.

The first light module 102 further comprises a connector 115a, which is arranged at end 102a and is designed, by way of example, as a male connector. In the assembled state of the light module 102, one end 21a of the circuit board 21 corresponds to its end 102a. The connector 115a is arranged and attached to the circuit board 21 at end 21a.

Adjacent to the second end 112b, the second light module 112 has a third contact device 32. Analogous to the first contact device 30 of the light module 102, the contact device 32 of the second module 112 is designed with two contact elements 130 arranged symmetrically on both longitudinal sides of the light module 112, the contact elements 130 being configured to electrically contact each of the operating current supply conductors 126a. The contact elements 130 are designed with spring-loaded sections, each of which is attached to the circuit board 121, see [reference]. Fig. 6 . The contact elements 130 of the contact device 32 are each partially arranged in the area of a recess 24a in the edge of the circuit board 121 and can spring elastically into the recess 24a.

In the longitudinal walls of the housing component 120, this has opposing openings 110 through which, after assembly of the light module 112, one of the elements 130 of the contact device 32 protrudes from an outside of the light module 112.

The second light module 112 also has a connector 115b, which is arranged at end 112b and is designed, for example, as a female connector. In the assembled state of the light module 112, one end 121b of the circuit board 121 corresponds to its end 112b. The connector 115b is arranged and attached to the circuit board 121 at end 121b.

The connecting device 115b of the second module 112 is designed to correspond to the connecting device 115a of the first module 102, with the female connector 115b being connectable to the male connector 115a. The devices 115a and 115b can thus be plugged into one another for electrical coupling of the lighting modules 102 and 112, for example by inserting both lighting modules 102 and 112 into the interior 125 of the rail 109 and then sliding them towards each other.

A further connector 115a, designed as a male connector, particularly analogous to that of the first module 102, is arranged at the first end 112a of the second light module 112. One end 121a of the circuit board 121 corresponds to the end 112a of the module 112, with the connector 115a of the second module 112 being arranged at the end 121a on the circuit board 121. A further second light module 112 can thus be plugged into the end 112a if required and thus electrically coupled.

The first lighting module 102 is configured to receive electrical current from the conductor assembly 126 via the first contact device 30 to supply the module 102. Furthermore, the first lighting module 102 is configured to receive the control signal from the conductor assembly 126 via the second contact device 31. The second light module 112 is designed to receive electrical current from the conductor assembly 126 via the third contact device 32 for the supply of the second light module 112.

On the circuit board 21 of the first lighting module 102, an electronic arrangement 70 with electronic components, in particular control electronics, is provided. The arrangement 70 is configured to process the control signal received from the conductor assembly 126 via the contact device 31, for example the DALI signal, at least by interpreting the control signal. Depending on the received and at least interpreted control signal, the first lighting module 102 is controlled, for example dimmed.

Furthermore, depending on the received and interpreted control signal, an output signal is provided by means of the electronic arrangement 70. This output signal is transmitted via the coupling using the interlocking plug connectors 115a and 115b at the ends 102a and 112b to the second lighting module 112. The second lighting module 112 is controlled based on the signal transmitted via the connectors 115a and 115b. The control signal present at the conductor assembly 126 can thus be received by the first module 102 and translated for the control of the second module 112 as well.

The first lighting module 102 is operated as a "master" module, whereas the second lighting module 112 is a "slave" module subordinate to the first module 102. In the embodiment shown in the figures, the second lighting module 112 is not equipped with an arrangement 70 for interpreting control signals, such as DALI signals, provided at the conductor assembly 126. Furthermore, in the second lighting module 112, a contact device for tapping such control signals at the conductor assembly 126 is omitted. In this way, relatively expensive electronic components and corresponding costs, particularly for the interpretation of the control signal, can be saved in the second lighting module or "slave" inset 112, and the complexity of the modules 112 can be reduced.

The output signal provided by the first module 102, which allows the second lighting module 112 to be controlled as a "slave" together with the first lighting module 102 as a "master", can be based, for example, on pulse-width modulation or pulse-pause modulation. For instance, the output signal can be provided as a signal correlated with a dim level and passed to the second module 112.

If desired, another "slave" lighting module 112 can be controlled via the additional connection device 115a at the end of 112a.

While the second lighting module 112 is directly coupled to the operating current supply conductors 126a for energy supply, the control of the second module 112 is carried out via the first module 102 and together with it.

The light modules 102, 112 each have one or more light sources, which are designed as strip-shaped LEDs on the circuit boards 21 and 121 using a chip-on-board (COB) process, thus achieving uniform light emission without visible light points. In this embodiment, the insets 102, 112 and the rail 109 are elongated with relatively small cross-sectional dimensions. With this design, chip-on-board light sources are well suited to achieving an aesthetically pleasing, uniform lighting effect.

The lighting arrangement 100 thus allows for savings on expensive electronic components while simultaneously achieving controllability and a flexible, modular design. Furthermore, the design described above, particularly the lighting modules 102 and 112, enables a construction that is not only economical and efficient but also space-saving, which is especially advantageous for a slim and elegant design of the lighting system 100.

Furthermore, in another variant of the lighting arrangement 100, it is conceivable to insert several first lighting modules 102 into the rail 109. In such a variant, for example, each of the first lighting modules 102 can be coupled with one or more second lighting modules 112 in the manner described above. Alternatively, it can be provided, for example, that at least one of the first lighting modules 102 is coupled with one or more second lighting modules 112 in the manner described above, while at least one further of the first lighting modules 102 is used without a coupled second lighting module 112. In this way, for example, the lighting effects and control options can be varied in many ways.

Although the invention has been fully described above with reference to preferred embodiments, it is not limited to these, but can be modified in many different ways.

The exemplary embodiments were selected and described to best illustrate the principles underlying the invention and its practical applications. This enables those skilled in the art to optimally modify and utilize the invention and its various embodiments with regard to the intended purpose. In the claims and the description, the terms "including" and "comprising" are used as neutral language terms for the corresponding terms "comprehensive." Furthermore, the use of the terms "a,""a," and "an" is not intended to fundamentally exclude multiple features and components described in this way.
