DETAILED DESCRIPTION
[0048] FIG. 1 schematically shows a network assembly or interconnect according to an embodiment. The network assembly 1 comprises a base module 2 with a logic unit 3, a communication bus 4 and extension modules 5, which are functionally connected to the logic unit 3. In the embodiment example of FIG. 1, there are three extension modules 5 that are connected to the logic unit 3. An extension module 5 in the form of a Zigbee module 6 and an extension module 5 in the form of a sensor module 7 are connected to the logic unit 3 via the communication bus 4. An extension 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 be connected to an LMS 20 (shown symbolically in FIG. 1).
[0049] FIG. 2 schematically shows a network assembly according to a further embodiment. The network assembly 1 or interconnect of FIG. 2 comprises a base module 2 with a logic unit 3 and extension modules 5, which are functionally connected to the logic unit 3. The functional connection between the logic unit 3 and the extension modules 5 is shown schematically by double-sided arrows. The extension modules 5 can be functional devices as well as communication modules. In this embodiment, the network assembly 1 represents a standalone luminaire, wherein one of the extension modules 5 is designed as an LED driver for light control of the luminaire.
[0050] The extension modules 5 are connected to the logic unit 3 via a communication bus or ILB (not shown in FIG. 2) similar to FIG. 1. In particular, the logic unit 3 can be configured in such a way that the functional connection or communication via the communication bus between the logic unit 3 and the extension modules 5 can take place via a system-internal or proprietary communication protocol. In some embodiments, all extension 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 & play interface, to which in particular an LED driver can be directly connected. The plug & play interface can be designed as a protected proprietary interface so that the use of non-approved or non-qualified LED drivers or other extension modules can be prevented. In particular, the logic unit 3 can be configured in such a way that an LED driver that does not have microcontroller-based intrinsic intelligence can be connected directly to the plug-&-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 controlled directly by the logic unit 3. For the LED driver or for further extension modules 5, which have their own intelligence or their own microcontroller, the 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 extension modules 5 or peripherals via the ILB and to receive, process and send messages to peripherals via the ILB in a standalone mode, in particular without integration of the network assembly 1 in an LMS.
[0051] FIG. 3 schematically shows a network assembly according to another embodiment. The network assembly 1 of FIG. 3 corresponds essentially to the network assembly 1 of FIG. 2 and additionally has an extension module in the form of a communication module 30, via which the network assembly 1 can be connected to an LMS 20 (shown symbolically). The further extension 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 designed 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. After detecting a communication module 30 connected to the communication bus 4, the logic unit 3 can in particular be configured to configure the communication module accordingly and initialise it for participation in a corresponding LMS 20. The flowchart of FIG. 6 below shows the corresponding process flow.
[0052] FIG. 4 schematically shows a network assembly according to a further embodiment. The network assembly 1 of FIG. 4 corresponds essentially to the network assembly 1 of FIG. 3 and additionally has a further communication module 30. Thus, in addition to a first communication module 30, the network assembly 1 of FIG. 4 has a second communication module 30, wherein the network assembly 1 can be connected to an LMS 20 (shown symbolically) via the first communication module 30 and the second communication module 30. The embodiment shown in FIG. 4 corresponds in particular to the case when the number of functional devices reaches the limit of a communication module for proper operation in an LMS, after which a further communication module of the same type is attached to the logic. The logic unit 3 may in particular be configured to be connected to a plurality of communication modules 30, 30 via the communication bus 4 or ILB so as to ensure proper operation of several functional devices in an LMS. In particular, the logic unit 3 may be configured to assign functional devices to the individual communication modules 30, 30 so that the network assembly 1 can be easily scaled by accommodating additional functional devices. For example, some extension modules 5 or functional devices can be assigned to the first communication module 30 and other extension modules 5 or functional devices can be assigned to the second communication module 30.
[0053] FIG. 5 schematically shows a network assembly according to another embodiment. The network assembly 1 of FIG. 5 corresponds essentially to the network assembly 1 of FIG. 4. Here, FIG. 5 refers to an application when the customer is given the option of displaying the extension 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 embodiment shown, two different communication modules 30, 30 are used, which can be configured by the logic unit 3. In this case, the logic unit 3 changes to a multi-master mode operation due to the simultaneous existence of two different LMS 20, 20.
[0054] The network assemblies described in FIGS. 1, 3, 4 and 5 above can be designed to subsequently calibrate a luminaire for more precise colour control and optimised maintenance. For example, the measurements can be performed on luminaires with the same luminaire type provided 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 or if necessary used in the installation, which has an online update capability (e.g., ZigBee peripheral). This calibration data may include, in particular, information on the warmest and coldest colour temperature, the nominal luminous flux and the power of the luminaire, and/or a Colour Rendering Index (CRI), as well as information on manufacturers, etc. An implementation example of such a subsequent calibration is shown as a flow chart in FIG. 7.
[0055] FIG. 6 shows a flowchart of a method for configuring an extension module according to an embodiment. The method 100 for configuring an extension module or peripheral shown in FIG. 6 can be performed in particular in one of the network assemblies shown in FIGS. 1, 3, 4, and 5. According to the embodiment of the method 100 shown in FIG. 6, after a start 105 of the method 100, in the method step 110 a search is made for a peripheral or an extension module 5 connected to the base module 2, in particular via the communication bus 4 or ILB. In the subsequent step 115, the peripheral or extension module 5 found is configured for the communication bus or ILB. By configuring the extension module in the method step 115, the extension module 5 or peripheral is enabled to participate in the communication via the communication bus 4. In a query step 120, it is queried whether the extension module or peripheral found is a communication module.
[0056] If the query in step 120 shows that the extension module 5 found is a communication module, then in method step 125 the communication module can be designated to represent a functional device already present in the network assembly 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 the method step 135, the factory settings of the functional device necessary for participation in the LMS are then sent to the communication module 30. In the method step 140, the peripheral or the communication module found is activated for participation in the LMS. The method 100 for configuring the extension module is then ended with the method step 145.
[0057] If the query step 120 shows that the extension module is not a communication module, the extension module is recognised as a functional device in the method step 150. In the following method step 155, the functional device is initialised and the method is ended with the method step 145.
[0058] FIG. 7 shows a flowchart of a method for calibrating a luminaire. In particular, the method 200 shown in FIG. 7 can be performed to calibrate a luminaire having an internal architecture according to one of the network assemblies shown in FIGS. 1 to 5. According to the embodiment example of the method 200 shown in FIG. 7, after a start 205 of the method 200, a query 210 is performed by the logic unit 3 as to whether a luminaire is present or connected to the ILB. If the query 210 shows that a luminaire is present, a luminaire, in particular of the same luminaire type, is measured for calibration in the method step 215. In the method step 220, calibration data are detected and in the method step 225, the detected calibration data are transmitted to an online-capable peripheral or communication module of the network assembly. In the following step 230, the logic unit 3 is informed of the data received and the control, in particular the colour control of the luminaire, is adjusted accordingly. In the method step 235, the luminaire data are made available to the LMS and the method is ended with the 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 to be measured in method step 245.
[0059] This calibration option allows customers to minimise the logistical effort associated with commissioning an LMS. This is because usually the luminaires with an LED driver are individually calibrated in the factory. With the luminaires described here, the luminaires can be purchased flexibly, in particular from desired manufacturers, and only calibrated subsequently, in particular according to the calibration method described above.
[0060] In addition to the possibility of subsequent factory-independent calibration, the platform design-based network assemblies described above offer a number of advantages. Such network assemblies or systems can, for example, be easily scaled up by connecting further extension modules, in particular functional devices and/or communication modules, to the communication bus or ILB. Furthermore, functional devices can be used flexibly, as required, in different networks or LMS 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 assembly simplifies the change from one, for example outdated, LMS to another, in particular future-proof, LMS without having to discard the already existing functional devices. In addition to direct economic advantages, this can be of decisive importance for both luminaire manufacturers and customers, especially with regard to the circular economy and ever stricter environmental regulations. The ability to subsequently calibrate the luminaires makes it possible to achieve precise light colour control and high-quality Human Centric Lighting (HCL), for example by imitating daylight particularly realistically.
[0061] FIG. 8 shows a network assembly in the form of a luminaire according to an embodiment. In the embodiment of FIG. 8, the luminaire 60 is designed as a so-called LED pendant luminaire. The luminaire 60 comprises an LED light source or LED light engine (not shown) for generating an LED light, a housing 61 with a light emission 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 light source, a network assembly 1 (not shown) comprising a communication bus 4 or ILB according to any of the aspects described above. The network assembly 1 is realised in the luminaire 60 by means of a base module 2 (not shown) in the form of an interconnect module connected to the driver 8, as illustrated below in FIG. 9. It is understood that FIG. 8 shows an exemplary design of a luminaire and that the network assembly described here is not limited to a specific electrical load or to a specific luminaire.
[0062] FIG. 9 shows a network assembly with a driver according to a further embodiment. In the embodiment of FIG. 9, the driver 8 is designed to control a luminaire, for example the luminaire shown 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. In FIG. 9 two extension modules 5 schematically shown as an example, 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 for controlling the luminaire on the basis of the detected motion signal. However, the communication bus 4 or the interface 9 is designed to be connected to more than two extension modules, in particular to a plurality of extension modules. In particular, due to the expandability of the luminaire 60 by connecting further participants or connectivity peripherals or extension modules to the communication module 4 or ILB, such an interconnect luminaire is able to communicate with an LMS or to be controlled by it on the basis of bus-capable sensors or sensor peripherals.
[0063] FIG. 10 shows a schematic circuit diagram of an extension module according to an embodiment. In this embodiment, the extension module 5 is in the form of a circuit device 70. In particular, the circuit device may be formed as an extension module 5 or part of an extension module 5 for connection to the communication bus 4 of a network assembly 1. The circuit device 70 comprises an input 71, in particular a power input, having an input terminal, and an output 72, in particular a power output, having an output terminal, wherein the input 71 and the output 72 being connected to one another via a controllable switch contact, in particular a switch 74 or power switch which can be driven by a switch driver 73. The switch 74 may be a relay switch and/or a semiconductor switch. The circuit device 70 has a control unit 75, a measuring device 76 or sensor system and a control input 77 or control interface.
[0064] 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 may be configured to detect the measurement signal generated by the measurement device 76 and to control the switch driver 73 to turn 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 assembly 1. The measuring device 76 may in particular comprise a power measuring unit, in particular comprising a Hall sensor and/or shunt, and be configured to measure the power consumption of the connected loads, in particular luminaires. The results of this power measurement can be transmitted to an LMS via the communication bus 4. The circuit device 70 can be designed as an external component and/or as a component integrated in a luminaire.
[0065] The measuring device 76 can be used in particular to read out power data, and the switch 74 can be used to control the luminaire on the basis of the power data detected, in particular remote control. The circuit device 70 is 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 act as a central switch for further switches or slave switches, so that an LMS with several switches can be implemented in a simple and cost-effective manner.
[0066] FIG. 11 shows a schematic circuit diagram of an application example of the extension module according to FIG. 10. In the application example shown in FIG. 11, the circuit device 70 or the master/slave box is used to control a luminaire 60. FIG. 11 also shows a power supply circuit with power supply lines L and N for supplying power to the luminaire 60. The circuit device 70 according to FIG. 10 is connected to the power supply circuit 80 with the input 71 and with the output 72. The circuit device 70 is connected in series with the luminaire 60 in such a way that the electrical current must flow through the switch 74 of the circuit device 70 in order to supply the luminaire 60 with electrical energy. Thus, the circuit device 70 performs the object of a switch, in particular a conventional switch, which switches the luminaires off and on by interrupting or establishing the power supply. FIG. 11 also shows a driver 8 as well as 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 circuit device 70 via the communication bus 4 or ILB. Communication with an LMS 20 or the integration of sensors or further extension modules can be carried out via the communication bus 4 shown, which also enables the integration of sensors, ZigBee or DALI components. FIG. 11 illustrates that the circuit device 70 can in principle be used to control any type of electrical loads or luminaire, in particular conventional luminaires. 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 circuit device 70 can be configured or dimensioned in particular for the specific application so that the circuit device 70 can withstand the maximum currents to be expected. The circuit breaker can be controlled via the bus system or ILB, as described above, so that the switch 74 or switching contacts of the switch 74 can be controlled by an LMS, in particular using connectivity peripherals, or also by sensors, in particular using sensor peripherals.
[0067] The power supply for the supply of the bus system or ILB can be provided continuously or uninterruptedly by the interconnect light. In this way, maximum availability of the system or the functionality of the circuit device 70 is ensured. By using such extension modules, the work and costs involved in changing from conventional lighting solutions, in which in particular several luminaires are switched on and off with a switch directly or on the mains side, to LMS-based lighting solutions can be reduced. In addition, LMS offer various functions for automation and remote maintenance etc. of lighting solutions. The functions of remote lighting control (on/off) and/or power consumption measurement described above can also be realised with the help of an LMS. If, for example, buildings with conventional lighting systems are to be converted to lighting systems based on a lighting management system, this involves costly modifications. In particular, these changes may involve the replacement of individual components (e.g., drivers) and/orusuallythe replacement of complete luminaires.
[0068] Even in the case of a new installation of an LMS (e.g., in a new building), additional costs are incurred, as the use of intelligent luminaires or drivers is also required here. Consequently, LMS or luminaires configured for LMS are always associated with higher costs compared to conventional lighting solutions. The principles described here enable conventional lighting installations to be upgraded 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 cheaper alternative to full LMS. In particular, functions such as remote control by LMS or sensors, reporting of energy consumption and rudimentary diagnostic functions can be realised.
[0069] Although at least one exemplary embodiment has been shown in the foregoing description, various changes and modifications may be made. The aforementioned embodiments are examples only and are not intended to limit the scope, applicability or configuration of the present disclosure in any way. Rather, the foregoing description provides the person skilled in the art with a plan for implementing at least one exemplary embodiment, wherein numerous changes in the function and arrangement of elements described in an exemplary embodiment may be made without departing from the scope of protection of the appended claims and their legal equivalents. Furthermore, according to the principles described herein, several modules or several products can also be connected with each other in order to obtain further functions.
