Description

[0001] The present disclosure generally relates to network structures. More specifically, the present disclosure relates to expansion modules for expanding the functionality of a network structure.

[0002] Electronic devices, in particular lighting devices or operating devices for lights, are becoming increasingly complex and have an increasing number of functionalities, which are generally implemented by corresponding functional units such as sensors, communication interfaces, remote control units, intelligent electronics, or similar. Network-capable electronic devices or network devices are also known that can participate in device networks or IoT (Internet of Things), such as lights or lighting devices in a light management system or LMS (Light Management System). In particular, connecting a light to an IoT network or LMS can be implemented using additional, network-specific hardware and software units, which can fundamentally be different for each network. Furthermore, electronic devices and lights are constantly being modified or upgraded.upgraded to meet the requirements for functionality, controllability, and network capability. Existing devices or additional units cannot easily be used for other networks or other purposes, which can lead to high costs and significant environmental impacts.

[0003] The document US 2019 / 0 166 673 A1 describes a test device for a lighting system with an input connection that corresponds to an output connection of a driver, and with an output connection that corresponds to an input connection of an alternator, wherein the test device is designed as a device independent of the driver and the alternator. The document DE 20 2015 104 940 U1 describes a connection terminal for the electrical connection of bus-capable operating devices for lamps, wherein the bus is live in the idle state, and wherein the connection terminal has input connections and output connections for a mains voltage supply. The document DE 10 2010 003 597 A1 describes an operating device for operating a lamp, wherein the operating device has an interface for connection to a bus line and a transmission branch coupled to the interface.The document EP 2 194 762 A1 describes a method for controlling and monitoring an emergency and safety lighting system of a luminaire and a monitoring and control module assigned to the luminaire.

[0004] An object of the embodiments of the present disclosure is to provide a simple and cost-effective way of expanding the functionality of existing electronic devices or lighting devices.

[0005] To achieve this object, according to a first aspect, an extension module for functionally expanding a network structure of a lighting management system is provided, wherein the network structure has a communication bus or bus system for providing communication between a logic unit of a base module of the network structure and the one or more extension modules, one or more functional devices and / or communication modules.

[0006] The expansion module is designed or configured to be connected to the communication bus of the network structure for expanding the functions or providing the functions of the network structure, in order to provide at least one additional function or additional functionality of an electrical load connected to the network structure in the form of a luminaire of the lighting management system. The expansion module comprises a power section for integrating the expansion module into the power supply circuit of the at least one load and a control section with a control unit for controlling the power section, the control unit being designed to receive calibration data for the luminaire via the communication bus and to control the luminaire according to the calibration data received via the communication bus. The additional functions can in particular include control and / or network functions of the electrical consumption.In particular, the additional functions can enable the electrical load, in particular a light, to be controlled by a device management system (LMS) and / or sensors. The extension module can be implemented separately or as part of a functional device, for example, a light.

[0007] The expansion module can comprise a power section for integrating the expansion module into the power supply circuit or power grid circuit of the at least one consumer, and a control section with a control unit for controlling the power section. In particular, the power section can be configured to be connected in series with the consumer in the power grid circuit, so that the electrical power provided to the consumer can be easily controlled by controlling the power section.

[0008] The power section can, in particular, comprise a circuit breaker for switching the at least one consumer on and off, in particular by closing and opening the power supply circuit. The circuit breaker can thus be used to easily interrupt the power circuit of the at least one consumer when needed.

[0009] The control section of the expansion module can include a control interface for connecting the control section of the expansion module to the communication bus or ILB (Intra Luminaire Bus). The control interface thus provides the control section of the expansion module with network capability, allowing the expansion module to be controlled by a network, particularly by an LMS.

[0010] In some embodiments, the expansion module comprises a measuring device for detecting at least one current parameter, in particular an electrical parameter, of the electrical load. In particular, the measuring device can be configured to detect performance and / or diagnostic data for the at least one electrical load. The current value of parameters as well as performance and diagnostic data can be used, for example, for controlling and / or diagnosing lights in an LMS.

[0011] The measuring device can, in particular, comprise a Hall sensor and / or a shunt for detecting the at least one electrical parameter. Hall sensors or shunts are readily available and are suitable for tapping current electrical parameters from an electrical circuit.

[0012] The additional function can, in particular, comprise controlling the at least one consumer, in particular a light. By connecting the expansion module to the network structure, the functionality of the electrical consumer can thus be subsequently expanded to include the control function. Control can, in particular, be based on the recorded value of the at least one parameter or the performance and / or diagnostic data, so that the current operating state of the consumer is taken into account when controlling the at least one consumer or the light.

[0013] In some embodiments, the expansion module is designed as a master module for controlling one or more slave modules. In particular, the expansion module can function as a central switch for additional switches or "slave" switches, allowing a LMS with multiple switches, particularly for a large number of luminaires, to be implemented in a simple and cost-effective manner.

[0014] The base module may comprise a logic or logic unit configured to be connected to a communication bus, in particular to an internal communication bus of the network structure, for providing communication between the logic unit and one or more expansion modules or peripherals, in particular one or more functional devices and / or communication modules, for functional expansion or functional provision of the network structure.

[0015] The communication bus can be configured, in particular, to transmit data or signals between the logic unit and the expansion modules. In some embodiments, the communication bus is configured to supply one or more expansion modules with electrical power. The communication bus can, in particular, comprise signal lines for serial communication or transmission of messages and / or supply lines for supplying power to the expansion modules or peripherals. In some embodiments, the communication bus is configured as part of the base module. In particular, the communication bus can be configured to be connected to a plurality of functional devices and / or communication modules as expansion modules in order to provide desired functionalities.

[0016] The logic unit represents, in particular, the central component or node through which, in particular, all network communication can take place. The logic or logic unit therefore plays a central role in such a modular network structure. The logic unit can forward, process, and / or modify information according to the intended operating scenarios. The logic unit can, in particular, comprise a microcontroller with a processor for data processing, with a memory unit for storing data and machine-readable code for the processor, and with an interface for connecting the logic unit to the communication bus. The logic unit or microcontroller can further comprise one or more further interfaces, in particular for configuring digital inputs and outputs and / or for translating measurement signals.In this context, configuring the logic unit to perform specific actions means that corresponding machine-readable instructions for the processor are stored in the memory unit of the logic unit to perform these actions.

[0017] The logic unit can be configured such that communication via the communication bus between the logic unit and the expansion modules can take place, in particular exclusively, via a system-internal or proprietary communication protocol. The system-internal or proprietary communication protocol can, in particular, make unauthorized access to the communication bus of the network structure more difficult or impossible. In particular, the use of the system-internal or proprietary communication protocol can make it more difficult or impossible to connect unauthorized expansion modules to the base module. Thus, the communication bus can serve as a protected, proprietary interface or ILB (Intra Luminaire Bus) for exchanging data or messages between the logic unit and the expansion modules or peripherals.

[0018] The functional devices or peripherals can in particular comprise sensors or various sensors, drivers, in particular LED drivers, push buttons and / or other devices. In the case of a luminaire, a functional device can be designed to detect or control the amount of light generated by the luminaire. A luminaire can in particular have one or more light sources. In particular, a luminaire can comprise a light source for generating indirect light, such as in a diffusely lit lighting device, and a light source for generating direct light, such as in a light spotlight. The amount of light can be controlled directly via the logic unit or via the LMS in which the luminaire is integrated. The functional devices can also be used to record and / or transmit data to the LMS. For example, the functional devices can comprise CO2 and / or temperature sensors that measure the current CO2 concentration orRecord or monitor the temperature value and provide the recorded data, for example, for the purpose of building maintenance. This information can also be used to optimize energy consumption or increase the efficiency of operational processes.

[0019] The one or more communication modules can comprise a module designed for wireless communication. The extension module can in particular comprise a ZigBee, Bluetooth or DALI interface. ZigBee® is a registered trademark of the ZigBee Alliance. Bluetooth® is a registered trademark of the Bluetooth Special Interest Group. DALI® (Digital Addressable Lighting Interface) is a registered trademark of the international standardization consortium for lighting and building automation networks. By using standardized interfaces, functional devices connected to the communication module can be remotely controlled or integrated into an LMS using standard protocols. The communication module can in particular be designed to act as an interpreter between the logic unit and the LMS by communicating with the LMS using a standard protocol and via the internal or external interfaces.A proprietary communication bus protocol communicates with the logic unit. An LMS enables customers to control different luminaires individually or in groups and define lighting scenes from simple to complex. An extension module can also be both a communication module and a functional device, for example, a ZigBee module with an integrated PIR (passive infrared) sensor.

[0020] Because the logic unit can be connected to one or more expansion modules via the communication bus, the network structure around the logic unit as a central unit or "core module" can be modularly and flexibly expanded. Thus, the base module can be used to create an intelligent lighting system, allowing the customer to determine the functionality, complexity, and cost of control gear or luminaires and adapt them to their own needs. In particular, the base module represents a design platform that enables the free and flexible use of functional devices, if necessary in compliance with any norms, standards, and requirements, in the desired device network or lighting management system.

[0021] The logic unit can be configured to search for an expansion module connected to the communication bus via the communication bus. This search function enables the logic unit to determine whether one or another expansion module has been connected to the communication module and to respond accordingly if necessary. The logic unit can be configured to configure an expansion module for the communication bus if the search reveals that the expansion module is connected to the communication bus. In particular, the logic unit can automatically configure a communication module connected to the communication bus as intended, so that, for example, configuring a communication module automatically initializes the network structure for an LMS.

[0022] In some embodiments, the logic unit has a further interface, in particular a plug-and-play interface, for connecting a plug-and-play functional unit or a functional device that can be directly controlled by the logic unit via control signals. For example, an LED driver without microcontroller-based intelligence can be connected to the plug-and-play interface and directly controlled by the logic unit. In such a case, the LED driver's factory-set variables can be stored directly in the logic unit. Intelligent LED drivers with their own microcontrollers can be connected to the communication bus or ILB interface.

[0023] According to a second aspect, a network structure is provided. The network structure comprises a base module, a communication bus for providing communication between a logic unit of the base module and one or more expansion modules, wherein the network structure further comprises an expansion module according to the first aspect that can be connected to the communication bus of the network structure. The connectable expansion module can provide additional functions, in particular for control and / or network functions of the electrical load. In particular, the additional functions can enable the electrical load, in particular a light, to be controlled using a device management system or LMS and / or sensors. The expansion module can be designed separately or as part of a functional device, for example a light.

[0024] The network structure can, in particular, comprise a driver for driving an electrical load, wherein the extension module is designed as a driver extension module for connection to the driver, in particular via the communication module or ILB. Electronic devices, such as lights, that require a driver can be easily retrofitted with the extension module that can be connected to the driver.

[0025] The modular design of the network structure makes it easy to expand or retrofit the network structure with expansion modules.

[0026] The network structure can comprise at least one light source, in particular at least one LED light source, and at least one driver, in particular an LED driver, for driving the at least one light source. The at least one driver can be designed as a functional device connectable to the communication bus. In particular, the network structure can be designed as a light. Such a light can be easily equipped with additional functions by connecting additional expansion modules, such as additional functional devices and / or communication modules, to the communication bus.

[0027] In some versions, the network setup includes a plug-and-play LED driver connected to the logic unit's plug-and-play interface and can be controlled directly by the logic unit. This allows simple LED drivers that are unable to communicate with the logic unit via the system's internal communication bus to be controlled directly via the plug-and-play interface.

[0028] The at least one expansion module can comprise at least one communication module for connecting the network structure, in particular via a standardized protocol, to a network system or LMS. In particular, the at least one communication module can be designed as a communication module for wireless communication with a network system or LMS.

[0029] According to a third aspect, a luminaire is provided. The luminaire, which can be designed in particular as an LED luminaire, comprises a light source, in particular an LED light source or LED light engine, for generating light and a network structure with an extension module according to the first aspect, wherein the extension module is designed to provide additional functionality for the luminaire.

[0030] In particular, the expansion module can comprise a measuring device for detecting at least one current electrical parameter of the luminaire. In particular, the measuring device can be designed to detect performance and / or diagnostic data for the at least one electrical load. The current value of parameters as well as performance and diagnostic data can be used, for example, for controlling and / or diagnosing luminaires in an LMS. The diagnostic data can be used, in particular, for remote diagnosis of the luminaire or the LMS.

[0031] Fenner provides a method for configuring an expansion module of a network structure, wherein the network structure comprises a base module with a logic unit and a communication bus, in particular a system-internal communication bus, for providing communication, in particular data communication, between the logic unit and one or more expansion modules, in particular one or more functional devices and / or communication modules, for expanding or providing the functions of the network structure. The method comprises a search, in particular by the logic unit, for an expansion module connected to the communication bus. This search function enables the logic unit to determine whether one or another expansion module has been connected to the communication module in order to respond accordingly if necessary.The method further comprises configuring an expansion module for the communication bus if the search indicates that the expansion module has been connected to the communication bus. Thus, the logic unit can automatically configure an expansion module connected to the communication bus as intended, so that, for example, by configuring an expansion module, the network structure can be automatically initialized for an LMS.

[0032] The method may include querying whether the expansion module found during the search is a communication module. The expansion module may be designated to represent a functional device present in the network structure by the communication module in a network if the query reveals that the expansion module found during the search is a communication module. A communication module connected to the communication bus may thus be automatically configured, if necessary, to connect the network structure to the network, in particular the LMS.

[0033] Representing may include notifying the communication module of the type of functional device present. Thus, if necessary, the information about the type of functional device can be automatically forwarded via the communication module to the network, in particular the LMS.

[0034] The method may further include sending network-relevant or network-required factory settings of the functional device to the communication module. Thus, if necessary, the information about the factory settings of the functional device can be automatically forwarded to the network, in particular the LMS, via the communication module.

[0035] The network structure described above allows for retrofitting the luminaires, particularly after proper installation, in cases where the network structure includes an extension module configured as a luminaire. In particular, the calibration data can be recorded on a luminaire of the same type and transmitted to the network structure via an extension module configured as a communication module, particularly one with online capability. This allows retrofitting such luminaires regardless of the installation or manufacturer.

[0036] The invention will now be explained in more detail with reference to the accompanying figures. The same reference numerals are used throughout the figures for identical or equivalent parts. Fig. 1 shows schematically a network structure according to an embodiment, Fig. 2 shows schematically a network structure according to a further embodiment, Fig. 3 shows schematically a network structure according to another embodiment, Fig. 4 shows schematically a network structure according to another embodiment, Fig. 5 shows schematically a network structure according to another embodiment, Fig. 6 shows a flowchart of a method for configuring an expansion module according to an embodiment, Fig. 7 shows a flowchart of a method for calibrating a luminaire, Fig. 8 shows a network structure designed as a lamp according to an embodiment, Fig. 9 shows a network structure with a driver according to another embodiment, Fig. 10 shows a schematic diagram of an expansion module according to an embodiment, and Fig. 11 shows a schematic diagram of an application example of the extension module according to Fig. 10.

[0037] Fig. Figure 1 schematically shows a network structure or interconnect according to an embodiment. The network structure 1 comprises a base module 2 with a logic unit 3, a communication bus 4, and expansion modules 5, which are in a functional connection with the logic unit 3. In the embodiment of the Fig. 1, there are three expansion modules 5 connected to the logic unit 3. One expansion module 5 in the form of a Zigbee module 6 and one expansion module 5 in the form of a sensor module 7 are connected to the logic unit 3 via the communication bus 4. One expansion module 5 in the form of an LED driver 8 is connected to the logic unit 3 via an interface 9. Fig. 1 also shows a light source 10, which is electrically connected to the LED driver 8 and can be controlled by the LED driver 8. The Zigbee module 6 is designed to communicate with an LMS 20 (in Fig. 1 symbolically represented).

[0038] Fig. Figure 2 schematically shows a network structure according to another embodiment. The network structure 1 or interconnect of the Fig. 2 comprises a base module 2 with a logic unit 3 and expansion modules 5, which are functionally connected to the logic unit 3. The functional connection between the logic unit 3 and the expansion modules 5 is schematically represented by double-sided arrows. The expansion modules 5 can be both functional devices and communication modules. In this exemplary embodiment, the network structure 1 represents a standalone luminaire, with one of the expansion modules 5 being designed as an LED driver for controlling the luminaire's lighting.

[0039] The extension modules 5 are similar to Fig. 1 via a communication bus or ILB (in Fig. 2 not shown) is connected to the logic unit 3. The logic unit 3 can in particular be configured such that the functional connection or communication via the communication bus between the logic unit 3 and the expansion modules 5 can take place via a system-internal or proprietary communication protocol. In some embodiments, all expansion modules 5 are connected to the logic unit 3 exclusively via a proprietary ILB. In some embodiments, the logic unit 3 has an additional interface, in particular a plug-and-play interface, to which in particular an LED driver can be directly connected. The plug-and-play interface can be designed as a protected proprietary interface, so that the use of unauthorized or unqualified LED drivers or other expansion modules can be prevented.In particular, the logic unit 3 can be configured such that an LED driver that does not have its own microcontroller-based intelligence can be connected directly to the plug-and-play interface. In such a case, any factory-set variables of the LED driver can be stored directly in the logic unit, so that the LED driver can be directly controlled by the logic unit 3. For the LED drivers or for further expansion modules 5 that have their own intelligence or their own microcontroller, connection to the logic unit 3 is possible via the communication bus 4 or ILB. The logic unit 3 can be designed to search for expansion modules 5 or peripherals via the ILB and, in a standalone mode, in particular without integrating the network structure 1 into an LMS, to receive, process, and send messages to peripherals via the ILB.

[0040] Fig. Figure 3 schematically shows a network structure according to another embodiment. The network structure 1 of Fig. 3 essentially corresponds to the network structure 1 of the Fig. 2 and additionally has an expansion module in the form of a communication module 30, via which the network structure 1 can be connected to an LMS 20 (symbolically shown). The further expansion modules 5, which are designed as functional devices, are connected to the communication module 30 via the logic unit 3. The connection between the functional devices and the communication module 30 can be flexibly configured via the logic unit 3. In particular, the functional devices can be assigned to the communication module 30 via the logic unit 3 individually, in groups, or not at all. The logic unit 3 can in particular be configured, after detecting a communication module 30 connected to the communication bus 4, to configure it accordingly and to initialize it for participation in a corresponding LMS 20. The flowchart of the Fig. 6 below shows the corresponding process flow.

[0041] Fig. Figure 4 schematically shows a network structure according to another embodiment. The network structure 1 of Fig. 4 essentially corresponds to the network structure 1 of the Fig. 3 and additionally has a further communication module 30'. Thus, the network structure 1 of the Fig. 4 has a second communication module 30' in addition to a first communication module 30, wherein the network structure 1 can be connected to an LMS 20 (symbolically shown) via the first communication module 30 and the second communication module 30'. Fig. The embodiment shown in Figure 4 corresponds in particular to the case where the number of functional devices reaches the limit of a communication module for proper operation in an LMS, after which another communication module of the same type is attached to the logic unit. The logic unit 3 can in particular be configured to be connected to a plurality of communication modules 30, 30' via the communication bus 4 or ILB, so that proper operation of several functional devices in an LMS can be ensured. The logic unit 3 can in particular be configured to assign functional devices to the individual communication modules 30, 30', so that the network structure 1 can be easily scaled by incorporating additional functional devices. For example, some expansion modules 5 or functional devices can be assigned to the first communication module 30 and other expansion modules 5' or functional devices can be assigned to the second communication module 30'.

[0042] Fig. Figure 5 schematically shows a network structure according to another embodiment. The network structure 1 of Fig. 5 essentially corresponds to the network structure 1 of the Fig. 4.

[0043] This refers to Fig. 5 refers to an application where the customer is given the option of representing the expansion modules 5, 5' or functional devices connected to the logic unit 3 alternatively or simultaneously in two LMS 20, 20'. For this purpose, according to the illustrated embodiment, two different communication modules 30, 30' are used, which can be configured by the logic unit 3. In this case, the logic unit 3 switches to multi-master mode operation, due to the simultaneous existence of two different LMS 20, 20'.

[0044] The Fig. 1, Fig. 3, Fig. 4 and Fig. 5 Network setups described above can be configured to retrofit a luminaire for more precise color control and optimized maintenance. For example, measurements can be performed on luminaires of the same type, and the calibration data can be made available to the existing installation as an online update. For this option, an extension module or peripheral is installed in the setup, or used if necessary, which has an "online update" capability (e.g., ZigBee peripheral). This calibration data can include, in particular, information about the warmest and coldest color temperature, the nominal luminous flux and the power of the luminaire, and / or a Color Rendering Index (CRI), as well as information about the manufacturer, etc. An implementation example of such a retrofit calibration is described in Fig. 7 is shown as a flow chart.

[0045] Fig. 6 shows a flowchart of a method for configuring an expansion module according to an embodiment. Fig. The method 100 shown in Figure 6 for configuring an expansion module or peripheral can be used in particular in one of the network structures according to Fig. 1, Fig. 3, Fig. 4, and Fig. 5. According to the Fig. In the exemplary embodiment of the method 100 shown in Figure 6, after a start 105 of the method 100, a search is carried out in method step 110 for a peripheral or an expansion module 5 connected to the base module 2, in particular via the communication bus 4 or ILB. In the subsequent step 115, the found peripheral or expansion module 5 is configured for the communication bus or ILB. By configuring the expansion module in method step 115, the expansion module 5 or peripheral is enabled to participate in communication via the communication bus 4. In a query step 120, a query is made as to whether the found expansion module or peripheral is a communication module.

[0046] If the query in step 120 indicates that the found expansion module 5 is a communication module, the communication module can be designated in method step 125 to represent a functional device already present in the network structure 1 in an LMS. In method step 130, the peripheral or communication module 30 is then notified of the type of functional device to be represented. In method step 135, the factory settings of the functional device required for participation in the LMS are then sent to the communication module 30. In method step 140, the peripheral or the found communication module is activated for participation in the LMS. The method 100 for configuring the expansion module is then terminated with method step 145.

[0047] If query step 120 reveals that the expansion module is not a communication module, the expansion module is identified as a functional device in method step 150. In the subsequent method step 155, the functional device is initialized, and the method is terminated with method step 145.

[0048] Fig. Figure 7 shows a flowchart of a method for calibrating a luminaire. Fig. The method 200 shown in Figure 7 can be carried out in particular for calibrating a luminaire having an internal architecture according to one of the Fig. 1 to 5. According to the Fig. In the exemplary embodiment of the method 200 shown in Figure 7, after a start 205 of the method 200, a query 210 is carried out by the logic unit 3 as to whether a luminaire is present or connected to the ILB. If the query 210 results in the presence of a luminaire, then in method step 215 a luminaire, in particular of the same luminaire type, is measured for calibration. In method step 220, data for calibration are acquired, and in method step 225 the acquired data are transmitted to an online-capable peripheral or communication module of the network structure for calibration. In the subsequent step 230, the logic unit 3 is informed of the received data, and the control, in particular the color control of the luminaire, is adjusted accordingly. In method step 235, the luminaire data is made available to the LMS, and the method is terminated with method step 240.If the query in step 120 shows that no luminaire, in particular no luminaire with the required luminaire type, is available, a luminaire is requested for measurement in method step 245.

[0049] This calibration option allows customers to minimize the logistical effort associated with commissioning an LMS. Typically, luminaires are calibrated individually with an LED driver at the factory. With the luminaires described here, the luminaires can be purchased flexibly, particularly from desired manufacturers, and calibrated subsequently, particularly according to the calibration procedure described above.

[0050] In addition to the possibility of subsequent, factory-independent calibration, the platform-based network structures described above offer a number of advantages. Such network structures or systems can, for example, be easily scaled up by connecting additional expansion modules, in particular functional devices and / or communication modules, to the communication bus or ILB. Furthermore, functional devices can be flexibly deployed, as required, in different networks or LMSs or in a standalone device or luminaire. Furthermore, due to the flexibility of the communication modules, different functional devices can be integrated into an LMS both individually and simultaneously. The modularity of the network structure simplifies the transition from one, for example, outdated, LMS to another, particularly future-proof, LMS, without having to discard the existing functional devices.In addition to immediate economic benefits, this can be of crucial importance for both luminaire manufacturers and customers, especially with regard to the circular economy and increasingly stringent environmental regulations. The ability to subsequently calibrate luminaires enables precise light color control and high-quality Human Centric Lighting (HCL), for example, by realistically simulating daylight.

[0051] Fig. Figure 8 shows a network structure designed as a light according to an embodiment. In the embodiment of Fig. 8, the luminaire 60 is embodied, by way of example, as a so-called LED pendant luminaire. The luminaire 60 comprises an LED illuminant or LED light engine (not shown) for generating an LED light, a housing 61 with a light exit window 62, and a suspension device 63 for suspending the luminaire 60 from the ceiling. The luminaire 60 further comprises a driver 8 (not shown) for driving the LED light engine or the illuminant, a network structure 1 (not shown) with a communication bus 4 or ILB according to one of the aspects described above. The network structure 1 is implemented in the luminaire 60 by means of a base module 2 (not shown) embodied in the form of an interconnect module, which is connected to the driver 8, as described below in Fig. 9. It is understood that Fig. 8 represents an exemplary embodiment of a luminaire, and that the network structure described here is not limited to a specific electrical consumer or to a specific luminaire.

[0052] Fig. 9 shows a network structure with a driver according to another embodiment. In the embodiment of Fig. 9 is the driver 8 for controlling a light, for example the one in Fig. 8. A base module 2 or interconnect module with a communication bus 4 or ILB is connected to the driver 8. The base module 2 has an interface 9 for connecting extension modules 5 to the base module. Fig. Figure 9 schematically illustrates two example expansion modules 5, namely a Zigbee module 6 for providing wireless communication via the Zigbee protocol and a sensor module 7 with a motion detector for detecting a motion signal and controlling the luminaire based on the detected motion signal. However, the communication bus 4 or the interface 9 is designed to be connected to more than two, in particular to a plurality of, expansion modules. In particular, due to the expandability of the luminaire 60 by connecting additional participants or connectivity peripherals or expansion modules to the communication module 4 or ILB, such an "interconnect luminaire" is capable of communicating with an LMS or being controlled by it using bus-capable sensors or sensor peripherals.

[0053] Fig. 10 shows a schematic circuit diagram of an expansion module according to an embodiment. In this embodiment, the expansion module 5 is designed in the form of a switching device 70. The switching device can be designed in particular as an expansion module 5 or part of an expansion module 5 for connection to the communication bus 4 of a network structure 1. The switching device 70 comprises an input 71, in particular a power input, with an input terminal and an output 72, in particular a power output, with an output terminal, wherein the input 71 and the output 72 are connected to one another via a controllable switch contact, in particular a switch 74 or power switch that can be driven by a switch driver 73. A relay and / or a semiconductor switch can be used as the switch 74. The switching device 70 has a control unit 75, a measuring device 76 orSensors as well as a control input 77 or control interface.

[0054] The measuring device 76 is electrically connected to the input 71 and is designed to detect a current input parameter, in particular an output current, an input voltage and / or input power, and to send a measurement signal corresponding to the detected input parameter to the control unit 75. The control unit 75 can be designed to detect the measurement signal generated by the measuring device 76 and to control the switch driver 73 to switch the switch 74 on or off based on the detected measurement signal. The control input 77 is configured to be connected to the communication bus 4 or to the bus system or ILB of the network structure 1. The measuring device 76 can in particular have a power-measuring unit, in particular with a Hall sensor and / or shunt, and can be designed to measure the power consumption of the connected loads, in particular lights.The results of this power measurement can be transmitted to an LMS via the communication bus 4. The switching device 70 can be implemented as an external component and / or as a component integrated into a luminaire.

[0055] The measuring device 76 can be used, in particular, to read performance data, and the switch 74 can be used to control the luminaire, in particular remotely, based on the recorded performance data. The switching device 70 represents a so-called master / slave switch box and can be used to switch an external device, in particular a luminaire, on and off on the mains side. In particular, the switching device 70 can function as a central switch for additional switches or "slave" switches, so that an LMS with multiple switches can be implemented in a simple and cost-effective manner.

[0056] Fig. 11 shows a schematic diagram of an application example of the extension module according to Fig. 10. In the Fig. In the application example shown in Figure 11, the switching device 70 or the master / slave box is used to control a lamp 60. Fig. 11 also shows a power supply circuit with power lines L and N for supplying power to the lamp 60. The circuit device 70 according to Fig. 10 is connected to the power supply circuit 80 via input 71 and output 72. The switching device 70 is connected in series with the luminaire 60 such that, in order to supply the luminaire 60 with electrical energy, the electrical current must flow through the switch 74 of the switching device 70. Thus, the switching device 70 performs the function of a switch, particularly a conventional one, that switches the luminaires on and off by interrupting or establishing the power supply. Fig. 11 also shows a driver 8 and a base module 2 or interconnect module connected to the driver 8 according to Fig. 9, wherein the interface 9 of the base module 2 is electrically connected to the control input 77 of the switching device 70 via the communication bus 4 or ILB. Communication with an LMS 20 or the integration of sensors or additional expansion modules can be carried out via the illustrated communication bus 4, which also enables the integration of sensor, ZigBee, or DALI components. Fig.11 illustrates that the switching device 70 can fundamentally be used to control any type of electrical load or light, particularly conventional light. The power section, in particular the switch 74 as well as the input 71 or input terminal and the output 72 or output terminal, of the switching device 70 can be configured or dimensioned in a particularly application-specific manner, so that the switching device 70 can withstand the expected maximum currents. The power switch can be controlled, as described above, via the bus system or ILB, so that the switch 74 or switching contacts of the switch 74 can be controlled by an LMS, in particular using connectivity peripherals, or by sensors, in particular using sensor peripherals.

[0057] The power supply for the bus system or ILB can be provided continuously or uninterruptedly by the "interconnect light." This ensures maximum availability of the system and the functionality of the switching device 70. By using such expansion modules, the effort and cost involved in switching from conventional lighting solutions, in which, in particular, several lights are switched on and off directly or via the mains with a single switch, to LMS-based lighting solutions can be reduced. In addition, LMSs offer various functions for automation and remote maintenance, etc. of lighting solutions. The above-described functions of remote light control (on / off) and / or power consumption measurement can also be implemented using an LMS.For example, converting buildings with conventional lighting systems to lighting systems based on a lighting management system involves complex modifications. These modifications may include replacing individual components (e.g., drivers) and / or—usually—replacing entire luminaires.

[0058] Even the new installation of an LMS (e.g., in a new building) involves additional effort, as this also requires the use of intelligent luminaires or drivers. Consequently, LMS or luminaires configured for LMS are always more expensive than conventional lighting solutions. The principles described here enable the upgrade of conventional lighting installations so that they can be operated by a lighting management system. Furthermore, the principles described here can also be used for new installations as a more cost-effective alternative to full-fledged LMS. In particular, functions such as remote control via LMS or sensors, energy consumption reporting, and rudimentary diagnostic functions can be implemented.
