Description

[0001] The invention relates to a lamp comprising an electronic module with a magnetically triggered reset function. The electronic module can be reset using an external magnet, and in particular, reset to the factory settings (i.e., the delivery state), thereby affecting the functionality of the lamp as a whole.

[0002] Previously known luminaires with such an electronic module, which features a magnetic reset mechanism, can be reset particularly easily by bringing an external magnet close to the respective electronic module. For example, electronic modules are known that can be reset to factory settings by placing a strong external magnet (e.g., a neodymium magnet (e.g., N35, d = 6.35 mm xh = 1.59 mm)) near the electronic module for a few seconds (e.g., 5 seconds). It is usually sufficient to bring the external magnet close to the underside of the luminaire or to a corresponding front cover of the electronic module, so that the magnetic field generated by the external magnet triggers the magnetic reset mechanism of the electronic module.

[0003] Generally, in such luminaires, the respective electronic module is located on a front side and / or on an outer wall of the luminaire housing, since placing it inside the luminaire, i.e., integrating the electronic module into the housing, impairs the functionality of the electronic module (e.g., its radio range and / or its sensor).

[0004] The luminaires discussed here are generally used in a wide variety of lighting scenarios and can be deployed, for example, in open-plan offices, individual offices, meeting rooms, government offices, classrooms, power plants, hospitals, storage and break rooms, waiting rooms, corridors, stairwells, restrooms, prisons, hallways, halls, etc., as well as in other publicly accessible places or security areas. Essentially, they can be used anywhere a luminaire has an electronic module, such as a sensor and / or a radio module, etc., and this module has a corresponding magnetic reset function.

[0005] In these application scenarios and given the specific positioning of such a luminaire, there is a risk that unauthorized individuals could easily reset the luminaire, or its electronic module, to its factory settings using a simple, commercially available magnet. This would cause the luminaire to lose its connection to a lighting network, certain control parameters, and / or other settings, rendering it unusable until a (complex) reconfiguration is completed. This poses a risk that lighting systems and their individual luminaires could be easily disabled through vandalism.

[0006] One such well-known lamp 1001, which has an electronic module 1100 that has a magnetic reset mechanism 1110 by means of which the electronic module 100 can be reset to its factory settings, is inFig. Figure 1 shows that the magnetic reset mechanism 1110 is triggered when a magnetic field 1030 of a certain strength, generated by an external magnet 1020, is detected. For example, simply bringing a neodymium magnet (e.g., an N35 magnet) close for a few seconds (e.g., 5 seconds) could be sufficient to trigger the magnetic reset mechanism 1110 of the electronic module 1100. In the case of the known lights 1001, it is also sufficient if a corresponding external magnet 1020 is brought near a front cover 1200, which is arranged on the front 1011 of the light 1001 and covers the electronic module 1100, or a sensor opening 1300 of the front cover 1200, in order to activate the magnet reset mechanism 1110 and thus reset the module 1100 or the light 1001.The functionality of this well-known lamp 1001 can therefore be particularly easily impaired, as it is not vandal-proof.

[0007] The invention is therefore based on the objective of providing an improved lamp which has an electronic module with a magnetic reset mechanism, by means of which triggering the magnetic reset mechanism by unauthorized third parties is at least greatly made more difficult, and preferably prevented.

[0008] The luminaire according to the invention, or its exemplary embodiments, is ideally intended to be used analogously to previously known luminaires, and is characterized by a protective mechanism that at least makes unauthorized triggering of the reset mechanism more difficult, or preferably even prevents it.

[0009] This problem is solved according to the invention with the subject matter specified in independent claim 1. Particular embodiments of the invention are specified in the dependent claims.

[0010] According to the present invention, a luminaire is provided with a luminaire housing and an electronic module, wherein the electronic module is arranged on a front side and / or on an outer wall of the luminaire housing, and wherein the electronic module has a reset mechanism by means of which the electronic module can be reset to a factory default state. The reset mechanism is a magnetic reset mechanism, which is designed to trigger upon detection of a magnetic field of a specific magnetic field strength generated by an external magnet. Furthermore, according to the invention, the luminaire has a shielding device for shielding the magnetic field generated by the external magnet.

[0011] The luminaire, designed with a shielding device to block an external magnetic field, prevents unintentional and, in particular, unauthorized triggering of the reset mechanism. This is because the shielding device blocks the magnetic field of the external magnet, rendering the external magnetic field at the reset mechanism insufficiently strong (or ideally, non-existent) to trigger the magnetic reset mechanism. In this way, the shielding device suppresses the magnetic field influence of the external magnet on the luminaire's electronic module, thus preventing the reset mechanism from being activated. Specifically, this prevents unintentional or unauthorized resetting using a conventional (compact) external magnet.

[0012] In a specific design of the luminaire, or rather its shielding device, it may be provided that, for example, the reset mechanism can still be triggered when using a suitably sized professional magnet, so that maintenance and adjustment of the luminaire, or rather the electronic module, is still possible using magnetism, but only with a professional magnet. This professional magnet, used by a suitably authorized and trained technician, could be, for example, a suitably sized permanent magnet or an electromagnet.

[0013] Optionally, the shielding device can be designed to physically shield the magnetic field generated by the external magnet. Alternatively or additionally, the shielding device can be designed to magnetically shield the magnetic field generated by the external magnet. In this case, the shielding device for physical shielding preferably comprises a physical element that shields the external magnetic field of the external magnet, wherein, in particular, a physical element is arranged between the electronic module (or its magnetic reset mechanism) and the external magnet, which at least (significantly) weakens or even completely shields the magnetic field of the external magnet. The shielding device for magnetic shielding, on the other hand, itself generates a magnetic field that at least weakens and preferably even neutralizes the magnetic field of the external magnet.Furthermore, it is conceivable that the two types of shielding devices are used in combination, so that the respective luminaire then has both a shielding device for physical shielding and a shielding device for magnetic shielding, both of which work synergistically together and thus particularly advantageously shield the magnetic field caused by the external magnet.

[0014] Optionally, the shielding device can be implemented by a protective cover located on the luminaire housing in the vicinity of the electronic module, the protective cover being at least partially made of metal. Alternatively or additionally, the shielding device can be implemented by an internal magnet located in the vicinity of the electronic module, particularly on the electronic module itself. In this case, the protective cover can be a shielding device for the physical shielding of the magnetic field generated by the external magnet. The internal magnet, in turn, represents a possible implementation of the shielding device for the magnetic shielding of the magnetic field generated by the external magnet.The protective covering can also be present in combination with the internal magnet, whereby both components work synergistically together and thus shield the external magnetic field particularly advantageously.

[0015] Optionally, the protective casing can be made of metal, metallized plastic, a metal mesh, or plastic with an integrated metal mesh. These various exemplary implementations of the protective casing as a (component of the) shielding device provide a particularly simple and efficient element for shielding the external magnetic field of an external magnet. While a purely metal protective casing (especially one made of ferromagnetic metal) is particularly effective in shielding the external magnetic field, such a design could detract from the luminaire's aesthetics. Implementations made of metallized plastic (especially one made of ferromagnetic metal) can maintain or even improve the luminaire's aesthetics while also achieving sufficient shielding.By implementing the metal mesh in the style of a Faraday cage, sufficient shielding can also be achieved, also in combination with a sheathed plastic layer.

[0016] Optionally, the protective cover may have an insertion opening for the guided positioning of an external professional magnet.

[0017] This makes it particularly easy to access the functionality of the electronic module's reset mechanism, although the opening naturally impairs the shielding function, ideally only slightly. Furthermore, such an access opening ensures that only trained personnel, such as technicians, are authorized to operate the reset mechanism, thus still providing protection against vandalism.

[0018] Optionally, the internal magnet can be designed to generate a counter-magnetic field that opposes the magnetic field produced by the external magnet, thereby minimizing or neutralizing it. This counter-magnetic field makes it particularly easy to weaken or neutralize the magnetic field of the external magnet.

[0019] Optionally, the internal magnet can be a permanent magnet or an electromagnet. While a permanent magnet is particularly inexpensive and easy to use, being positioned and integrated into the electronic module, an electromagnet is characterized by its flexible controllability and variable strength. Furthermore, using an electromagnet as the internal magnet makes it especially easy to implement a scenario in which the magnetic reset mechanism needs to be made accessible, for example, when a reset to factory settings of the electronic module, and thus also of the light, is required or desired.

[0020] Optionally, the electromagnet can be connected to a power supply to provide an operating voltage, with the electromagnet being designed to generate the counter-magnetic field when the operating voltage is active. Connecting the electromagnet to a power supply makes it particularly easy to operate. This can be achieved using external power supplies, such as the mains electricity supply, and / or internal power supplies, such as the internal energy storage of a lamp. Therefore, it is possible to provide the operating voltage via a mains connection. With such an exemplary implementation, the shielding device for magnetic shielding is designed to be particularly simple and flexible.

[0021] Optionally, the luminaire may also include an energy storage device, the energy storage device being electrically coupled to the electromagnet and configured to supply the electromagnet with the operating voltage. Preferably, the energy storage device is configured to supply the electromagnet with the operating voltage when the power supply via the mains connection fails. This ensures the shielding of the electronic module's reset mechanism even in a scenario where the luminaire or its components are not powered by an external power supply, such as a general mains connection, at least for the period during which the energy storage device can supply the electromagnet with a corresponding operating voltage.This ensures, in particular, that for luminaires which can continue operating despite a failure of the main power supply, for example during a power outage, the electronic module is protected against unauthorized or unintentional reset even in these exceptional situations, thus guaranteeing the operational reliability of the luminaire. The energy storage device is preferably recharged when the mains connection is functional, i.e., when the power supply via the mains is working, so that the shielding device can then be active again even in extreme situations such as a power outage.

[0022] Optionally, the energy storage device can be a supercapacitor and / or a battery. This provides particularly simple and cost-effective ways to implement such an energy storage system for the lamp's internal electromagnet, each of which can reliably supply the electromagnet with the operating voltage.

[0023] Optionally, the energy storage system can be designed to supply the electromagnet with operating voltage for a specific period, in particular 1 hour, 3 hours, 5 hours, or an intermediate period, in the event of a power outage. This ensures, in particular, that short, medium, and / or long power outages can be bridged, thus guaranteeing the functionality of the shielding device even in these extreme situations.

[0024] Optionally, the luminaire can also be equipped with a control unit that is coupled to the electromagnet via a control channel. This control unit is designed to control the electromagnet, specifically to activate and deactivate it. This allows for particularly simple activation and / or deactivation of the shielding device, enabling the luminaire's reset mechanism to be selectively enabled—i.e., triggered—and then selectively shielded again. This further simplifies the maintenance and repair of the luminaire.

[0025] Optionally, the control unit can be configured to receive external control signals via a communication channel and, based on these signals, control the electromagnet. This communication channel can be either wired or wireless. This simplifies the control of the electromagnet and / or the shielding device, and the various control options via the communication channels create a particularly simple and flexible control system that can be integrated into existing lighting systems.

[0026] Optionally, the electronic module can be a radio module and / or a sensor module. These exemplary configurations of the electronic module are the most common modules that feature a corresponding magnetic reset mechanism.

[0027] Optionally, the luminaire may also have a front cover to at least partially conceal the front of the luminaire housing, preferably covering the electronic module from the front. The front cover protects the interior of the luminaire and also improves its aesthetics. In this exemplary embodiment, the front cover also prevents direct viewing of the electronic module, further enhancing the luminaire's appearance. Preferably, the front cover has an opening, in particular a sensor opening, for placing a sensor of the electronic module. This opening allows for the necessary external components, such as a sensor or a radio module, to be positioned accordingly.Furthermore, the opening is preferably also present in the protective casing, so that the protective casing, or rather the physical shielding device, does not (significantly) restrict the functionality of the electronic module. Nevertheless, it is always ensured that the shielding device protects the magnetic reset mechanism of the electronic module from the magnetic field of an external magnet, and thus shields it.

[0028] Therefore, various implementations of such a luminaire are given, with the individual designs advantageously further developing the shielding device of the luminaire.

[0029] The invention will be explained in more detail below with reference to the various embodiments and their designs, and with reference to the drawings. These show: Fig. 1 a schematic sketch of a known lamp with an electronic module with a magnetic reset mechanism; Fig. 2 a schematic sketch representation of an exemplary embodiment of a luminaire according to the invention with an electronic module having a magnetic reset mechanism and a shielding device for the physical shielding of a magnetic field caused by an external magnet; Fig. 3 a schematic sketch representation of an exemplary embodiment of a lamp according to the invention with an electronic module having a magnetic reset mechanism and a shielding device for magnetic shielding of a magnetic field caused by an external magnet; Fig. 4 a schematic sketch representation of an exemplary embodiment of a luminaire according to the invention with an electronic module having a magnetic reset mechanism and a shielding device for the physical and magnetic shielding of a magnetic field caused by an external magnet; Fig. 5 a schematic sketch representation of an exemplary embodiment of a lamp according to the invention with an electronic module having a magnetic reset mechanism, an energy storage device and a shielding device for magnetic shielding of a magnetic field caused by an external magnet; Fig. 6 a schematic sketch representation of an exemplary embodiment of a lamp according to the invention with an electronic module having a magnetic reset mechanism, an energy storage device and a shielding device for the physical and magnetic shielding of a magnetic field caused by an external magnet; Fig. 7 a schematic sketch representation of an exemplary embodiment of a lamp according to the invention with an electronic module with a magnetic reset mechanism, an energy storage device, a control unit and a shielding device for magnetic shielding of a magnetic field caused by an external magnet; Fig. 8 a schematic sketch representation of an exemplary embodiment of a luminaire according to the invention with an electronic module having a magnetic reset mechanism, an energy storage device, a control unit and a shielding device for the physical and magnetic shielding of a magnetic field caused by an external magnet.

[0030] The various Fig. Figures 2 to 8 show different exemplary implementations of a shielding device for a luminaire 1, as well as its function-enhancing additional components. It is evident that the exemplary designs of the individual Fig. The designs shown in numbers 2 to 8 can also be applied to other implementations of other figures.

[0031] The in the Fig. Exemplary embodiments of a luminaire 1 according to the invention, shown in 2 to 8, always depict the Fig. Figure 1 describes the basic structure of such a luminaire 1. The luminaire 1 comprises a housing 10 and an electronic module 100, the electronic module 100 being located on a front side 11 and / or on an outer wall 12 of the housing 10. The arrangement on the front side 11 or outer wall 12 is relevant because otherwise the functionality of the electronic module would be limited. For example, a module located deep inside the housing 10 could lead to significant malfunctions. However, with the arrangement on the front side 11 or outer wall 12, the electronic module 100 is easily accessible from the outside and thus particularly susceptible to vandalism. The electronic module 100 has a reset mechanism 110 by means of which it can be restored to its factory default state.Specifically, the reset mechanism 110 is a magnetic reset mechanism 110, which is designed to trigger a magnetic field of a certain strength upon detection of a magnetic field 30 caused by an external magnet 20.

[0032] The arrangement on the front 11 or the outer wall 12, however, allows for the easy insertion or positioning of an external magnet 20, which has a corresponding magnetic field 30, particularly by unauthorized persons (e.g., vandals). This would expose the electronic module 100 to this magnetic field 30 particularly easily, as already described above with regard to the known luminaires 1000. The luminaire 1 according to the invention is characterized, however, by the fact that the luminaire 1 has a shielding device 400, 410, 420 for shielding the magnetic field 30 generated by the external magnet 20. This prevents unintentional or unauthorized triggering of the magnetic reset mechanism 110 of the electronic module 10 of the luminaire 1 and improves the operational reliability and functionality of the luminaire 1.

[0033] In the exemplary embodiments shown, the luminaire 1 also always has a front cover 200, which is arranged on the front side 11 of the luminaire 1 and at least partially covers the electronic module 100. Specifically, the front cover 200 can also be directly associated with the electronic module 100 and cover it from the front side 11 of the luminaire 1. Preferably, the front cover 200 also has an opening 300 through which parts of the electronic module 100 can be guided to an outside of the luminaire 1, so that the functionality of the electronic module 100 and thus of the luminaire 1 is not impaired. In this respect, the opening 300 can specifically be designed as a sensor opening 300 for placing a sensor of the electronic module 100 (not shown in the figures). As further shown in the Fig. 2, Fig. 4, Fig. 6 and Fig. As outlined in Figure 8, the physical implementation of the shielding device 400, and in particular the protective covering 410, can also have the opening 300.

[0034] In the exemplary configurations shown, the electronic modules 100 are mostly designed as radio modules and / or sensor modules, as these exemplary configurations of the electronic module 100 are the most widespread modules that have a corresponding magnetic reset mechanism. However, other electronic modules 100 are obviously also conceivable for use in the luminaire 1 discussed here, provided they also have a corresponding magnetic reset mechanism.

[0035] While the Fig. 2. By way of example, the implementation of a luminaire 1 with a physically effective barrier 410 as a shielding device 400, 410, 420 for the physical shielding of a magnetic field 30 caused by an external magnet 20 shows, represents Fig. Figure 3 shows an analogous arrangement of a magnetic barrier 420 as a shielding device 400, 410, 420 for the magnetic shielding of a magnetic field 30 caused by an external magnet 20. Here, the physically effective barrier 410 is shown by way of example as a protective covering 410, and the magnetic barrier 420 as an internal magnet 420. In Fig. Figure 4 shows an exemplary embodiment in which the luminaire 1 has both a physical barrier 410 and a magnetic barrier 420 as a shielding device 400, 410, 420. In the Fig. 5 and Fig. Figure 6 shows an exemplary embodiment of the luminaire 1, in which the luminaire 1 further comprises an energy storage device 800 for supplying power to the magnetic barrier 420, or to the internal magnet 420. Fig. 7 and Fig. Figure 8 shows further exemplary designs of the luminaire 1 in which the luminaire 1 has a control unit 900 for controlling the magnetic barrier 420, or the internal magnet 420.

[0036] Other embodiments of the luminaire 1 are also conceivable – not shown. In particular, an implementation is possible in which the luminaire 1 has a control unit 900 but no energy storage device 800.

[0037] The Fig. Figure 2 shows a shielding device 400, which is designed for the physical shielding of the magnetic field 30 generated by the external magnet 20 and is specifically implemented as a protective cover 410, which is arranged on the luminaire housing 10 in the vicinity of the electronic module 100. The protective cover 410 is at least partially made of metal. By arranging the protective cover 410 on the luminaire housing 10, particularly in the region of the electronic module 100, the protective cover 410 shields the magnetic field 30 of the external magnet 20.

[0038] The protective cladding 410, which consists at least partially of (ferro)metal, provides a particularly cost-effective, simple, and effective shielding solution. Several specific implementations of the physical shielding, or rather the protective cladding 410, are conceivable. Versions in which the physical shielding, or rather the protective cladding 410, is made of metal, and / or metallized plastic, and / or a metal mesh, and / or plastic with an integrated metal mesh, are possible. Each of these different designs offers advantages in terms of shielding performance, weight, production costs, and the aesthetics of the protective cladding 410.

[0039] The Fig. Figure 3 shows an alternative design of the shielding device 400, in which the shielding device 400 is configured for magnetic shielding of the magnetic field 30 generated by the external magnet 20. Specifically, the shielding device 400 is implemented here by an internal magnet 420, which is arranged in the vicinity of the electronic module 100, in particular on the electronic module 100. The internal magnet 420 is configured to generate a counter-magnetic field that opposes the magnetic field 30 generated by the external magnet 20 and, in particular, minimizes or neutralizes it.

[0040] The internal magnet 420 can be either a permanent magnet or an electromagnet. In the electromagnet configuration, it is connected to a power supply in the exemplary embodiments and is designed to generate the opposing magnetic field when the operating voltage is active (not shown in the figures). The power supply can be provided, in particular, via a mains power connection.

[0041] The Fig. Figure 4 shows a combined implementation of the shielding device 400, wherein the shielding device 400 provides both magnetic shielding and physical shielding of the magnetic field 30 generated by the external magnet 20. Specifically, the exemplary embodiment shows that the luminaire 1 has both a protective cover 410 and an internal magnet 420 as shielding devices 400, which act synergistically together.

[0042] Also in Fig. Figure 4 shows an exemplary implementation of the protective cover 410, in which the protective cover 410 has an insertion opening 411 for the guided positioning of an external professional magnet. This enables a technician to selectively trigger the reset mechanism 110 of the electronic module 100 by inserting a suitable professional magnet through the insertion opening 411. Thus, protection against unintentional or unauthorized reset by the shielding device 400 is still ensured, while in particular the maintenance and repair of the luminaire 1 and the electronic module 100 is nevertheless facilitated.

[0043] In general, implementations are also conceivable in which the shielding device 400 (both with regard to its physical implementation, for example as a protective cover 410, and with regard to its magnetic implementation as an internal magnet 420) does not completely shield the magnetic field 30 of the external magnet 20. However, it is always achieved that the remaining magnetic field strength present at the reset mechanism 110 is lower than a predetermined threshold value above which the reset mechanism 110 would be triggered, so that sufficient shielding by the shielding device 400 is accomplished.The dimensions of the shielding device 400 can preferably be adapted to conventional magnets, which are typically used in vandalism cases – for example, the shielding device 400 can be adapted to various types and strengths of external magnets, such as a neodymium magnet N35. This design has the further advantage that professional external magnets, which are particularly large and / or strong and usually only available to specialists, such as technicians, can be used to deliberately and intentionally trigger the reset mechanism 110 of a respective electronic module 100 of a luminaire 1, despite the shielding device 400 still being in place for the previously discussed external magnets 20.

[0044] The Fig. Figure 5 shows another exemplary embodiment of the luminaire 1, which now additionally includes an energy storage device 800. The energy storage device 800 is electrically coupled to the electromagnet 420 and is further configured to supply the electromagnet 420 with the operating voltage, particularly when the power supply via the mains connection fails. In the embodiment shown, the energy storage device 800 is formed by a supercapacitor and / or by a battery. Furthermore, the energy storage device 800 is dimensioned such that, in the event of a failure of the power supply via the mains connection, it supplies the electromagnet 420 with the operating voltage for a certain period of time, in particular a period of one, three, or five hours (or an intermediate period).This ensures that the shielding device 400 with an internal magnet 420, and in particular with an electromagnet 420 as an internal magnet 420, is supplied with the required operating voltage even in the event of a power failure or when the luminaire 1 or the electromagnet 420 is disconnected from the mains power supply, thus keeping the shielding device 400 active.

[0045] This concept of the 800 energy storage system is further explained in Fig. Figure 6 shows that the luminaire 1 also has a physical shielding component in the shielding device 400, in addition to the protective cover 410. This ensures that even in the event of a complete failure of the electromagnet 420 (i.e., the magnetic shielding component of the shielding device 400) – for example, if the energy storage device 400 can no longer supply energy – a certain degree of shielding of the magnetic field 30 generated by the external magnet 20 is maintained.

[0046] In the Fig. 7 and Fig. Eight are each exemplary further development of a luminaire 1, whereby in Fig. 7 as already in Fig. 3 and Fig. 5 an embodiment of the luminaire 1 is sketched in which the shielding device 400 is implemented only magnetically, i.e., has only one internal magnet 420, in particular an electromagnet 420; and wherein in Fig. 8 as already in Fig. 4 and Fig. 6 an embodiment of the luminaire 1 is sketched in which the shielding device 400 is implemented both magnetically and physically, i.e. having both an internal magnet 420 (in particular an electromagnet 420) and a protective cover 410.

[0047] In both Fig. 7 and Fig. In Figure 8, the luminaire also features a control unit 900 in addition to the previously discussed energy storage device 800. Of course, versions are also conceivable in which the luminaire 1 has a control unit 900 without an energy storage device 800. The control unit 900 shown here is coupled to the electromagnet 420 via a control channel 920 and is further configured to control the electromagnet 420, and in particular to activate and deactivate it. Thus, in the exemplary implementations shown, the Fig. 7 and Fig. 8. The magnetic effect of the shielding device 400 can be controlled in a targeted manner, and in particular, activated and deactivated. This allows, for example, an authorized technician to selectively (partially) deactivate the shielding device 400 in order to selectively trigger the magnetic reset mechanism 110 of the electronic module 100 using a suitable professional magnet. However, unintentional and unauthorized triggering of the reset mechanism 110 is still prevented, since the electromagnet 420 is otherwise activated by appropriate control via the control channel 920, and thus the magnetic implementation of the shielding device 420 effectively shields a magnetic field 30 generated by an external magnet 20.

[0048] In particular, it can be provided that the control unit 900 can receive external control signals via a communication channel 910 and process them accordingly, i.e., control the electromagnet 420 based on the received external control signals. These external control signals can be sent and received via a wired communication channel 911 or alternatively or additionally via a wireless communication channel 912. For example, a central unit of a lighting system could control the control unit 900 via a respective communication channel 910, 911, or 912. This allows the luminaire 1, or the shielding device 400, 410, or 420, to be controlled particularly easily, flexibly, and reliably, and thus the reset mechanism 110 of the electronic module 100 to be triggered particularly easily, flexibly, and precisely.

[0049] Exemplary implementations are also conceivable in which the control unit 900 is also coupled with the energy storage unit 800, and controls its energy supply to the electromagnet 420.

[0050] Of course, in addition to the exemplary designs shown, the Fig. 7 and Fig. 8. Other versions are also conceivable in which the wireless communication channel 912 is used in a luminaire 1 according to Fig. 7 is implemented, and vice versa, in which a wired communication channel 911 is implemented in a luminaire according to Fig. 8 is implemented.

[0051] The electronic module 100 can also be arranged on an outer wall 12 of the luminaire 1 (not shown in the figures), and can be positioned on either the inward-facing or the outward-facing side. An arrangement on the front side 11 is also conceivable, as illustrated by example in the figures.

[0052] The physical implementation of the shielding device 400, and in particular the protective cover 410, can also be customized with a desired color depending on the chosen material composition, for example, to match the underside of the luminaire 1, so that the presence of a respective electronic module 100 with a magnetic reset mechanism 110, or a magnetic reset function 110, is not readily apparent to a layperson or unauthorized person. This is particularly easy and aesthetically pleasing to achieve with the aforementioned design made of metallized plastic.

[0053] Thus, various implementations of a luminaire 1 are given, by means of which an unauthorized triggering of the reset mechanism 110 of the electronic module 100 of the luminaire 1 is at least made more difficult, or even prevented.
