[0003] Lighting system
[0004] FIELD OF THE INVENTION
[0005] The invention relates to a lighting system comprising a luminaire and a sensor module. The invention further relates to a sensor module. The invention further relates to a lighting arrangement comprising a plurality of said lighting systems according to the invention.
[0006] BACKGROUND OF THE INVENTION
[0007] The built environment is more and more equipped with intelligent lighting systems providing a higher energy efficiency, increased functionality, and improved user experience. Such intelligent lighting systems are typically enabled by various sensors monitoring conditions in the built environment, and controllers transforming the sensor readings into useful information or actuatable action in quasi-real time, for example by controlling the light of a luminaire.
[0008] Therefore, the product portfolio of Signify - and many other innovative lighting companies - comprises intelligent lighting systems with sensing functionalities. Since the lighting infrastructure provides a structured grid of locations with access to mains power and / or a data backbone, various sensors are nowadays integrated within the luminaire itself. For example, a sensing functionality is provided to an intelligent lighting system by connecting an add-on sensor module to a luminaire. A sensor module may thereby comprise multiple sensors with different sensor modalities - such as for example the Philips Interact SC 1500 Multi Sensor Bundle of Signify.
[0009] The lighting industry has established standards to facilitate the adoption of such sensor modules. For example, one of such standards is the Zhaga standard. Zhaga Book 20 defines e.g. a smart interface between an indoor LED luminaire and an add-on sensor module. The mechanical interface defined in the Zhaga Book 20 standard is a dedicated Zhaga slot - i.e. having certain standardized dimensions - into which an add-on sensor module may be mounted. Since these dimensions are limited to the Zhaga standard, a Zhaga compliant add-on sensor module has limited space (or: real estate) to accommodate multiple2024PF80489
[0010] 2
[0011] sensors. A limited space (or: real estate) within the module is a typical challenge for most of the add-on sensor modules.
[0012] Since add-on sensor modules are nowadays integrated in luminaires, their dimensions are limited and preferred to be as small as possible - also to limit using areas on the luminaire that can otherwise be used for lighting. However, due to the development to increasingly monitor various conditions in the built environment, it is desired to equip add-on sensor modules with a wider scala of sensors and / or more on-board intelligence (e.g. edge processing). This requires a challenging miniaturization of components.
[0013] Equipping a luminaire with an add-on sensor module also increases the Bill of Material (BoM) costs. Customers may therefore opt for a lighting system wherein not all luminaires are equipped with an add-on sensor module, but only a subset of luminaires. This however reduces the monitored (coverage) area, and thereby the accuracy of monitoring the built environment as such.
[0014] Hence, there is a clear need to improve monitoring conditions in the built environment with increasingly miniaturized sensor modules and at lower costs.
[0015] US20210180784A1 discloses a streetlight camera with at least two optical image sensors.
[0016] SUMMARY OF THE INVENTION
[0017] It is an object of the invention to provide an improved lighting system, which at least alleviates the problems and disadvantages mentioned above. Thereto, the invention provides a lighting system comprising a luminaire and a sensor module; wherein the luminaire comprises a light engine and a housing, wherein the housing comprises a planar slot; wherein the sensor module is at least partly arranged within the planar slot and releasably connected to the luminaire; wherein the sensor module comprises a main body with a central plane perpendicular to the planar slot; wherein the sensor module comprises a first range sensor having a first Field of View (FoVl) centered around a first main axis and a second range sensor having a second Field of View (FoV2) centered around a second main axis; wherein the sensor module comprises a support structure comprising a first support element and a second support element, wherein the support structure is connected to the main body, wherein the first range sensor is mounted on the first support element and the second range sensor is mounted on the second support element; wherein the first support element and the second support element are arranged such that: (i) the first main axis and the second main axis are directed away from the planar slot; (ii) the first range sensor and the second range2024PF80489
[0018] 3
[0019] sensor are arranged on opposite sides of a middle plane, wherein a plane angle between the central plane and the middle plane is at least 0 degrees and at most 75 degrees; (iii) a separation angle between the first main axis (110) and the second main axis (120) is at least 30 degrees and at most 150 degrees.
[0020] It is further an object of the invention to provide an improved sensor module for a lighting system, which at least alleviates the problems and disadvantages mentioned above. Thereto, the invention provides a sensor module for a luminaire, wherein the sensor module comprises a main body and a connector, wherein the main body comprises a central plane, wherein the connector comprises a planar connector plane, wherein the connector is configured to connect the sensor module to a (planar slot of a housing of a) luminaire; wherein the sensor module comprises a first range sensor having a first Field of View (FoVl) centered around a first main axis and a second range sensor having a second Field of View (FoV2) centered around a second main axis; wherein the sensor module comprises a support structure comprising a first support element and a second support element, wherein the support structure is connected to the main body, wherein the first range sensor is mounted on the first support element and the second range sensor is mounted on the second support element; wherein the first support element and the second support element are arranged such that: (i) the first main axis and the second main axis are directed away from the planar connector plane; (ii) the first range sensor and the second range sensor are arranged on opposite sides of a middle plane, wherein a plane angle between the central plane and the middle plane is at least 0 degrees and at most 75 degrees; (iii) a separation angle between the first main axis and the second main axis is at least 30 degrees and at most 150 degrees.
[0021] Thereby, advantages and / or embodiments applying to the lighting system according to the invention may mutatis mutandis apply to said sensor module according to the invention.
[0022] Hence, the invention does not only provide an improved architecture for miniaturizing, but also provides improved monitoring due to an extended Field-of-View. In an embodiment, the separation angle between the first main axis and the second main axis is at least 45 degrees and at most 135 degrees.
[0023] Hence, in the proposed lighting system, the sensor module is configured to be releasably connected to luminaire and, when connected, the sensor module is at least partly arranged within the planar slot. The luminaire may be configured to convey power to the sensor module. The sensor module may thereby benefit from access to power via the luminaire.2024PF80489
[0024] 4
[0025] The sensor module according to the present invention comprises a main body with a central plane perpendicular to the planar slot, a first range sensor having a first Field of View (FoVl) centered around a first main axis (Al), and a second range sensor having a second Field of View (FoV2) centered around a second main axis (A2). The sensor module further comprises a support structure comprising a first support element and a second support element. The support structure is connected to the main body. The first range sensor is mounted on the first support element. The second range sensor is mounted on the second support element. Said support structure may alternatively be phrased as a support frame.
[0026] Moreover, according to the present invention, he first main axis (Al) and the second main axis (A2) are directed away from the planar slot. Because the first range sensor and the second range sensor are arranged on opposite sides of said middle plane, and the separation angle (a) between the first main axis (Al) and the second main axis (A2) is at least 30 degrees and at most 150 degrees, this combination of (angled) range sensors render a wider Field of View for monitoring the environment (i.e. FoVl + FoV2).
[0027] In an embodiment, the middle plane is perpendicular to the planar slot, and the plane angle between the central plane and the middle plane is 0 degrees. The arrangement of such a middle plane may for example be an initial position of the support structure of the module.
[0028] Because the main axis (Al, A2) of at least one of the first range sensor and the second range sensor are slant relative to the middle plane, so as to achieve said separation angle (a), the range sensors according to the present invention occupy less real estate in the sensor module, compared to a configuration wherein said range sensors would have been directed perpendicular to the planar slot (i.e. viewing directly downwards). Due to saving real estate in the sensor module, this enables the main body of the sensor body to accommodate other sensors (that require a Field of View) as well. Hence, the sensor module according to the invention renders miniaturization and a more compact architecture, while rendering - as mentioned - a wider Field of View for monitoring the environment.
[0029] Moreover, because a single luminaire with a connected sensor module according to the invention can monitor a larger volume of the environment with its range sensors, less luminaires are required to be equipped with a costly sensor module to perform the same monitoring function. This reduces cost, but also alleviates the need for e.g. commissioning and servicing.2024PF80489
[0030] 5
[0031] All in all, the lighting system according to the present invention (comprising the luminaire and the sensor module) meets the need for improving monitoring conditions in the built environment with more miniaturization and at lower costs.
[0032] Said planar slot may alternatively be phrased as a planar surface of a slot. Alternatively, the lighting system according to the invention is provided, wherein the luminaire comprises the housing, wherein the housing comprises a planar surface comprising a planar slot (or: opening, or: aperture, or: hole), wherein the sensor module is at least partly arranged within said planar slot.
[0033] Said main body may for example be a module housing. Said main body may for example be a substrate. Said main body may for example be a PCB. Said main body may for example be a module housing comprising a substrate, wherein the support structure is connected to the substrate.
[0034] The first range sensor and the second range sensor may be individually controllable.
[0035] In an embodiment, the first main axis and the second main axis are directed away from the middle plane. Such an embodiment describes a configuration wherein the first range sensor and the second range sensor are arranged back-to-back, and have a Field of View pointing in different, opposing directions. Such a back-to-back configuration may be beneficial, for example, for miniaturization.
[0036] In an alternative embodiment, the first main axis and the second main axis are directed towards the middle plane. Such an embodiment describes a configuration wherein the first range sensor and the second range sensor are arranged face-to-face, but have a Field of View pointing in different, opposing directions. Such a face-to-face configuration may be beneficial, for example, for protecting the range sensors, or for integrating an optical window.
[0037] In an embodiment, the Field of View of the first range sensor may partly overlap the Field of View of the second range sensor. The overlapping area resulting therefrom may for example be at most 5% of the total Field of View of both range sensors combined.
[0038] In an embodiment, the first range sensor and the second range sensor are operated alternately in time. Since the range sensors according to the invention may be positioned relatively close to one another (i.e. e.g. within a small add-on module within the luminaire), such an embodiment may be advantageous for operating two different range sensors in time.2024PF80489
[0039] 6
[0040] The lighting system according to the present invention improves the monitoring of the built environment. However, the luminaire according to the invention can be mounted at different heights within the built environment, which may affect the coverage area of sensors present in the sensor module according to the invention (mounted within the planar slot of the luminaire). For example, the first range sensor and the second range sensor have a larger (sensor) cover area if the distance between these sensors and a sensing plane (e.g. a floor) becomes larger. Therefore, the present invention copes with this given by providing an adjustable separation angle. The separation angle may be adjusted by reorienting (or: moving) the first support element with the first range sensor and / or the second support element with the second range sensor relative to the middle plane (i.e. relative to one another).
[0041] Hence, in an embodiment, the support structure is adaptable from an initial state into an adapted state; wherein the separation angle is adjustable from an initial separation angle into an adapted separation angle by adapting the support structure from the initial state into the adapted state; wherein in the adapted state the first support element and / or the second support element are reoriented relative to the middle plane. Thus, the adapted separation angle may be larger than the initial separation angle, thereby widening the total Field-of-View. Or: the adapted separation angle may be smaller than the initial separation angle, thereby narrowing the Field-of-View.
[0042] Hence, sensor module according to the invention comprises a main body with a support structure connected thereto. The support structure comprises the first support element and the second support element. The first range sensor is mounted on the first support element. The second range sensor is mounted on the second support element. The first support element and / or the second support element are reorientable (or: movable) relative to the middle plane. Such reorienting (or: moving) may adapt the support structure in the adapted state. The adaptation of the support structure will also automatically adjust the separation angle. Said first and second support elements may for example be at least one of: plates, protrusions, springs, frames, wires, bars, lead frames.
[0043] In an embodiment, the initial separation angle and the adapted separation angle may be at least 10 degrees different.
[0044] In an embodiment, the separation angle is adjustable from the initial separation angle into the adapted separation angle by plastically deforming the support structure from the initial state into the adapted state, the adapted state being a plastically deformed state.2024PF80489
[0045] 7
[0046] In an embodiment, the separation angle is adjustable from the initial separation angle into the adapted separation angle by elastically deforming the support structure from the initial state into the adapted state, the adapted state being an elastically deformed state; wherein the support structure comprises locking mechanism configured to lock the support structure in the elastically deformed state.
[0047] In an embodiment, the separation angle is adjustable from the initial separation angle into the adapted separation angle by folding the support structure from the initial state into the adapted state, the adapted state being a folded or unfolded state.
[0048] In an embodiment, the separation angle is adjustable from the initial separation angle into the adapted separation angle by sliding the support structure from the initial state into the adapted state.
[0049] In an embodiment, the support structure comprises an edge connecting the first support element to the second support element; wherein in the adapted state the first support element and the second support element are reoriented relative to the middle plane simultaneously by moving said edge. Because said edge connects the first support element and the second support element, the movement of said edge will also lead to reorientation (or: movement) of the first support element holding the first range sensor and the second support element holding the second range sensor. This will consequently render an adjusted separation angle. Said edge may be pulled, pushed, or moved. Thereby, at least one part of the first support element and / or the second support element may be fixed to the support structure, while the edge may be freely moving.
[0050] More specifically, in an embodiment, the support structure comprises an edge connecting the first support element to the second support element; wherein in the adapted state the first support element and the second support element are reoriented relative to the middle plane simultaneously by moving said edge within the middle plane and / or in a direction perpendicular to the edge.
[0051] The lighting system according to the present invention improves the monitoring of the built environment. However, in some situations, it may be desired that the Field-of-View of the range sensors is rotated relative to a sensing plane (e.g. a floor). For example, when the range sensors are at least partly viewing a wall, the resulting Field-of-View is not effectively utilized, and rotating the Field-of-View to a more useful view within the built environment is more desired.
[0052] Hence, in an embodiment, the support structure is pivotable from an initial state into a rotated state; wherein the plane angle is adjustable from an initial plane angle into2024PF80489
[0053] 8
[0054] a rotated plane angle by pivoting the support structure from the initial state into the rotated state, wherein the initial plane angle and the rotated plane angle are at least 10 degrees different.
[0055] In an embodiment, the sensor module comprises a visual indicator indicative of the separation angle. Such an embodiment facilitates selecting the desired separation angle for the sensor module, and thereby helps installing the sensor module.
[0056] In an embodiment, the planar slot is a Zhaga slot compliant with the Zhaga standard. Said planar slot may be a Zhaga slot. Said Zhaga slot may alternatively be phrased as Zhaga Book 20 slot, or Zhaga Fl luminaire slot.
[0057] In an embodiment, the first range sensor is a first Time of Flight (ToFl) sensor, and the second range sensor is a second Time of Flight (ToF2) sensor.
[0058] In an embodiment, wherein the main body of the sensor module comprises front surface and a sensor slot; wherein the front surface is arranged parallel to the planar slot and facing away from the luminaire, wherein the sensor slot is arranged on the front surface; wherein the support structure, the first range sensor and the second range sensor are at least partly arranged within the sensor slot, wherein a surface area of the sensor slot is at most 40% of a total surface area of the front surface.
[0059] In an embodiment, the sensor module comprises at least one further sensor with a further sensor type different to a sensor type of the first range sensor and the second range sensor.
[0060] Said further sensor may be at least one of: Single pixel thermopile, humidity sensor, temperature sensor, light sensor, sound pressure sensor, microphone, camera, PIR sensor, BLE receiver, Zigbee radio, IR receiver, thermopile array, TMOS sensor, radar, multi spectral sensor.
[0061] The lighting system according to the present invention comprises a luminaire and a sensor module, wherein the sensor module is mounted in the planar slot of the luminaire, and obtains power from the luminaire. The sensing functionality of the sensor module, as characterized with the first range sensor and the second range sensor, and optionally at least one further sensor, may be utilized to monitor the built environment and / or control an external device. For example, the sensor module may be utilized to control the luminaire.
[0062] In an embodiment, the first range sensor is configured to determine a first range input, and wherein the second range sensor is configured to determine a second range input; wherein the sensor module comprises an electronic circuit configured to convey a2024PF80489
[0063] 9
[0064] signal indicative of the first range input and / or the second range input. In an embodiment, the electronic circuit is a wireless communication module.
[0065] In an embodiment, wherein the lighting system comprises a controller configured to obtain the signal indicative of the first range input and / or the second range input, and wherein the controller is configured to control the light engine of the luminaire based on the first range input and / or the second range input.
[0066] In an embodiment, the controller is arranged physically remote from the luminaire and the sensor module. In an alternative embodiment, the controller is arranged within the sensor module. In an alternative embodiment, the controller is arranged within the light engine.
[0067] In an embodiment, the sensor module comprises a third range sensor having a third Field of View (FoV3) centered around a third main axis. The support structure may comprise a third support element, wherein the third range sensor may be mounted on said third support element. In a related embodiment, the third main axis is in the middle plane. Such an embodiment may be advantageous to monitor an area covered directly below the sensor module.
[0068] In an alternative embodiment, the sensor module comprises a third range sensor having a Field of View (FoV3) centered around a third main axis and a fourth range sensor having a fourth Field of View (FoV4) centered around a fourth main axis, wherein the support structure comprises a third support element and a fourth support element, wherein the third range sensor is mounted on the third support element and the fourth range sensor is mounted on the fourth support element; wherein the third support element and the fourth support element are arranged such that: (i) the third main axis and the fourth main axis are directed away from the planar slot, (ii) the third range sensor and the fourth range sensor are arranged on opposite sides of a further middle plane, wherein the further middle plane is orthogonal to the middle plane, wherein a further separation angle between the third main axis and the fourth main axis is at least 30 degrees and at most 150 degrees.
[0069] Hence, the sensor module may comprise a total of four range sensors, or phrased differently, two couples of range sensors that are arranged substantially orthogonal to one another. This improves monitoring the built environment. The sensor module may thus become a more omnidirectional sensor. In an embodiment, the third main axis and the fourth main axis are directed away from the further middle plane. In an embodiment, the third main axis and the fourth main axis are directed towards the further middle plane.2024PF80489
[0070] 10
[0071] In an embodiment, the support structure is adaptable from an initial state into an adapted state; wherein the further separation angle is adjustable from an initial further separation angle into an adapted further separation angle by adapting the support structure from the initial state into the adapted state; wherein in the adapted state the third support element and / or the fourth support element are reoriented relative to the further middle plane.
[0072] In an embodiment, the initial further separation angle and the adapted further separation angle are at least 10 degrees different.
[0073] In an embodiment, the further separation angle is adjustable from the initial further separation angle into the adapted further separation angle by plastically deforming the support structure from the initial state into the adapted state, the adapted state being a plastically deformed state.
[0074] In an embodiment, the further separation angle is adjustable from the initial further separation angle into the adapted further separation angle by elastically deforming the support structure from the initial state into the adapted state, the adapted state being an elastically deformed state; wherein the support structure comprises a further locking mechanism configured to lock the support structure in the elastically deformed state. Said locking mechanism and said further locking mechanism may be the same locking mechanism.
[0075] It is further an object of the invention to provide an improved lighting arrangement, which at least alleviates the problems and disadvantages mentioned above. Thereto, the invention provides a lighting arrangement comprising a plurality of said lighting systems according to the invention. Thereby, advantages and / or embodiments applying to the lighting system according to the invention may mutatis mutandis apply to said lighting arrangement according to the invention. The lighting arrangement may be installed in a space. The lighting arrangement may comprise a main controller for obtaining sensor inputs. Each of the lighting systems may monitor a different area within a space. Each respective range sensor may generate a range sensor input, which range sensor input may be conveyed by each respective sensor module to the main controller. The plurality of lighting systems may be arranged in a (regular) grid. The lighting arrangement may comprise a plurality of lighting systems without a sensor module.
[0076] Hence, in further aspects of the invention, the invention provides a sensor module for connecting to a luminaire, the sensor module comprising a main body, a support structure connected to the main body, a first range sensor having a first Field of View (FoVl) centered around a first main axis, and a second range sensor having a second Field of View2024PF80489

[0098] DETAILED DESCRIPTION OF THE EMBODIMENTS
[0099] Figure 1 depicts schematically, by non-limiting example, an embodiment of a lighting system 100 according to the invention. Figure 2 depicts schematically, by nonlimiting example, a sideview of said embodiment of a lighting system 100 according to the invention.
[0100] The lighting system 100 comprises a luminaire 20 and a sensor module 10. Figure 3 depicts, by non-limiting example, a perspective view of said sensor module 10 according to the invention.
[0101] The luminaire 20 comprises a light engine 21 and a housing 22. The light engine 21 is configured to illuminate, when in operation, the ambient environment 9. Said ambient environment may for example be an office space, a hospital ward, a sports venue, a retail establishment, etc.2024PF80489
[0102] 13
[0103] The sensor module 10 is arranged for releasably connecting to said luminaire 20. Therefore, the housing 22 of the luminaire 20 comprises a planar slot 23. Phrased differently, the housing 22 comprises a planar surface comprising a slot 23, said slot 23 being configured to releasably connect a sensor module to the luminaire 20. For example, said planar slot may be compliant with the Zhaga standard (e.g. Zhaga Book 20), and thus be a Zhaga slot, such as a Zhaga Fl luminaire sot.
[0104] Figures 1-3 depict the sensor module 10 being (releasably) connected to the luminaire 20. The sensor module 10 is thereby arranged within the planar slot 23. For example, the luminaire may comprise a luminaire connector 29 (e.g. a socket) connecting to a module connector 19 (e.g. a plug) of the sensor module. The luminaire 20 may for example convey power and / or data signals to the sensor module 10. The sensor module 10 may for example convey data signals to the luminaire 20. The sensor module 10 may be disconnected, released and detached from said sensor slot 23.
[0105] Referring to figures 1-3, the sensor module 10 comprises a main body 15. The main body 15 comprises a central plane 1. The central plane 1 is perpendicular to the planar slot 23. The sensor module 10 comprises a first range sensor 11 having a first Field-of-View (FoVl) 111 centered around a first main axis 110. The sensor module 10 also comprises a second range sensor 12 having a second Field-of-View (FoV2) 122 centered around a second main axis 120. Here, the first range sensor 11 is a first Time of Flight (ToFl) sensor, and the second range sensor 12 is a second Time of Flight (ToF2) sensor.
[0106] The sensor module 10 further comprises a support structure 16. This may alternatively be phrased as a support frame. The support structure 16 comprises a first support element 161 and a second support element 162. The first support element 161 comprises the first range sensor 11. Namely, the first range sensor 11 is (e.g. fixedly) mounted on the first support element 161. The second support element 162 comprises the second range sensor 12. Namely, the second range sensor 12 is (e.g. fixedly) mounted on the second support element 162.
[0107] Hence, first range sensor 11 monitors a first region within the ambient environment 9 and the second range sensor monitors a second region within the ambient environment 9. Such regions are not necessarily overlapping. In examples, the Field of View (FoVl) of the first range sensor may partly overlap the Field of View (FoV2) of the second range sensor.
[0108] Still referring to figures 1-3, the first support element 161 and the second support element 162 are arranged such that the first main axis 110 and the second main axis2024PF80489
[0109] 14
[0110] 120 are directed away from the planar slot 23. The range sensors 11, 12 are directed away from the luminaire 20. Thereby, the first support element 161 and the second support element 162 are also arranged such that a separation angle (a) 4 between the first main axis 110 and the second main axis 120 is at least 30 degrees and at most 150 degrees. Here, said separation angle (a) 4 is depicted as 45 degrees. Alternatively, the first main axis and the second main axis may be directed towards the middle plane.
[0111] Still referring to figures 1-3, the first support element 161 and the second support element 162 are arranged such that the first range sensor 11 and the second range sensor 12 are arranged on opposite sides of a middle plane 3. Moreover, the first main axis 110 and the second main axis 120 are directed away from the middle plane 3. Hence, the first range sensor 11 and the second range sensor 12 are arranged back-to-back in the sensor module 10.
[0112] Here, in the present embodiment, the middle plane 3 and the central plane 1 are the same. Hence, a plane angle (P) between the central plane 1 and the middle plane 23 is 0 degrees. Alternatively, said plane angle (P) between the central plane 1 and the middle plane 23 may be at least 0 degrees and at most 90 degrees, such as at least 0 degrees and at most 75 degrees.
[0113] Still referring to figures 1-3, because the first range sensor 11 and the second range sensor 12 are arranged back-to-back on opposite sides of said middle plane 3, and the separation angle (a) 4 between the first main axis 110 and the second main axis 120 is at least 30 degrees and at most 150 degrees (i.e. here embodied as 45 degrees), this configuration of a pair of angled range sensors renders a wider Field of View for monitoring the environment (i.e. FoVl + FoV2). The range sensors 11, 12 according to the present invention also occupy less real estate in the sensor module 10, compared to a configuration wherein said range sensors 11, 12 would have been directed perpendicular to the planar slot 12 (i.e. viewing directly downwards). This enables the main body 15 of the sensor module 10 to accommodate other sensors (that require a Field of View) as well.
[0114] For example, albeit optionally, but depicted in figure 2, the main body 15 of the sensor module 10 comprises front surface 17 and a sensor slot 13. The front surface 17 is thereby arranged parallel to the planar slot 23 and facing away from the luminaire 20. The sensor slot 13 is arranged on the front surface 17. The support structure 16, the first range sensor 11, and the second range sensor 12, are at least partly arranged within the sensor slot 13. Moreover, albeit optional, the surface area of the sensor slot 13 is at most 40% of a total2024PF80489
[0115] 15
[0116] surface area of the front surface 17. Hence, the sensor module 10 has sufficient space (or: real estate) to accommodate more electronics within the main body, such as other sensors.
[0117] For example, albeit optionally, but depicted in figure 2 and figure 3, the sensor module 10 comprises a further sensor 18 for monitoring the ambient environment 9. For example, the further sensor 18 may be a different type of sensor compared to the first range sensor 11 and the second range sensor 12. Said further sensor 18 may for example be a single pixel thermopile, humidity sensor, temperature sensor, light sensor, sound pressure sensor, microphone, camera, PIR sensor, BLE receiver, Zigbee radio, IR receiver, thermopile array, TMOS sensor, radar, multi spectral sensor
[0118] Still referring to figures 1-3, the luminaire 20 according to the invention comprises a (releasably) connected sensor module 10 that can monitor a larger volume of the ambient environment 9 with its range sensors 11, 12. Therefore, a single luminaire 20 may perform the same monitoring function as two separate luminaires. This reduces cost, but also alleviates the need for e.g. commissioning and servicing.
[0119] Still referring to figures 1-3, the lighting system 100 according to the present invention comprises the luminaire 20 and the sensor module 10, wherein the sensor module 10 is mounted in the planar slot 23 of the luminaire 20, and may obtain power from the luminaire 20. Alternatively, the sensor module battery powered, or powered via a photovoltaic cell. The sensing functionality of the sensor module 10, as characterized with the first range sensor 11 and the second range sensor 12 may be utilized to monitor the built environment 9 and / or control optionally an external device. For example, in the present embodiment, albeit optionally, the sensor module 10 is configured to control the luminaire 20.
[0120] Namely, the first range sensor 11 is configured to determine a first range input, and the second range sensor 12 is configured to determine a second range input. Thereby, albeit optionally, the first range sensor and the second range sensor are operated alternately in time, e.g. with an interleaving duty cycle. Alternatively, both range sensors are operated simultaneously or cooperatively. The sensor module 10 comprises an electronic circuit 18 configured to convey a signal indicative of the first range input and / or the second range input. The electronic circuit 18 conveys the signal wiredly. Here, albeit optionally and exemplary, the signal is conveyed via the module connector 19 to the luminaire connector 29 and subsequently to the light engine 22. Said communication circuit may for example communicate via DALI, DMX, PLC, Optical Communication, USB, Ethernet, etc.
[0121] Alternatively, the electronic circuit may be a wireless communication module.2024PF80489
[0122] 16
[0123] Furthermore, the lighting system 100 comprises a controller configured to obtain the signal indicative of the first range input and / or the second range input. The controller is configured to control the light engine 22 of the luminaire 20 based on the first range input and / or the second range input. Here, the controller is arranged physically remote from the sensor module 10, and in the light engine 22 of the luminaire 20. Alternatively, the controller may be arranged (elsewhere) in the luminaire, in the sensor module itself, and / or in an external device physically remote and separated from the luminaire and the sensor module.
[0124] The lighting system according to the present invention improves the monitoring of the built environment. However, the luminaire according to the invention can be mounted at different heights within the built environment, which may affect the coverage area of sensors present in the sensor module according to the invention. Therefore, the present invention copes with this given by providing an adjustable separation angle, as a consequence of an adjustable support structure.
[0125] Figure 4 depicts schematically, by non-limiting example, an embodiment of a lighting system 100’ according to the invention, wherein the lighting system 100’ of the embodiment depicted in figure 4 is similar to the lighting system 100 depicted in figures 1-3, but wherein the support structure and the separation angle are adjustable from an initial state (similar to the embodiment depicted in figures 1-3) into an adapted state (as depicted in figure 4).
[0126] More specifically, the support structure 16 is adaptable from an initial state 16 into an adapted state 16’. The first support element 161’ and / or the second support element 162’ are reorientable (or: movable) relative to the middle plane 3. In the adapted state, the first support element 161’ and / or the second support element 162’ are reoriented relative to the middle plane 3. Such reorienting (or: moving) may adapt the support structure 16 in the adapted state 16’. The adaptation of the support structure will also automatically adjust the separation angle.
[0127] Therefore, the separation angle 4 is adjusted from an initial separation angle 4 into an adapted separation angle 4’ by adapting the support structure 16 from the initial state 16 into the adapted state 16’. Here, the adapted separation angle 4’ is smaller than the initial separation angle 4, thereby narrowing the total Field-of-View. Alternatively, the adapted separation angle may be larger than the initial separation angle, thereby widening the Field-of-View. The initial separation angle 4 and the adapted separation angle 4’ may for example be at least 10 degrees different.2024PF80489
[0128] 17
[0129] Still referring to figure 4, in the present embodiment, the separation angle is adjustable from the initial separation angle 4 into the adapted separation angle 4’ by plastically deforming the support structure 16 from the initial state 16 into the adapted state 16’, the adapted state 16’ being a plastically deformed state. Hence, an engineer may manually adapt the separation angle accordingly.
[0130] Yet even further, albeit optionally, the support structure 16, 16’ comprises an edge 163 connecting the first support element 161’ to the second support element 162’. In the adapted state the first support element 161’ and the second support element 162’ are reoriented relative to the middle plane 3 simultaneously by moving said edge 163. Hence, the movement of said edge 163 will lead to reorientation (or: movement) of the first support element 161’ holding the first range sensor 11 and the second support element 162’ holding the second range sensor 12. This will consequently render the adjusted separation angle 4’. Said edge may be pulled, pushed, or moved. For example, as depicted in figure 4, the edge 163 is moved within the middle plane 3 and in a direction perpendicular to the edge 163. Other movements may be envisioned similarly.
[0131] Alternatively, in other examples, the separation angle is adjustable from the initial separation angle into the adapted separation angle by elastically deforming the support structure from the initial state into the adapted state, the adapted state being an elastically deformed state; wherein the support structure comprises locking mechanism configured to lock the support structure in the elastically deformed state.
[0132] For example, figure 5 depicts, by non-limiting example, a support structure 56 according to the present invention, wherein the support structure is elastically deformable. The support structure 56 may either be in an initial state I, or (moved) in an adapted state II.
[0133] The support structure 56 is connected to a main body (not depicted) of a sensor module (not depicted). The support structure 56 comprises a first support element 51 comprising a first range sensor 51 and a second support element 562 comprising a second support element 52. The first range sensor 51 has a first Field of View centered around a first main axis 510. The second range sensor 52 has a second Field of View centered around a second main axis 520. The first range sensor 51 is (fixedly) mounted on said first support element 561, and the second range sensor 52 is (fixedly) mounted on said second support element 562. The sensor module (not depicted) and support structure 56 comprises separation angle (a) 54 between the first main axis 510 and the second main axis 520. Here, the separation angle 54 in the initial state I is 100 degrees.2024PF80489
[0134] 18
[0135] The main body (not depicted) comprises a central plane 53. This is depicted in figure 5. The first support element 561 and the second support element 562 are arranged on opposite sides of a middle plane 57. Here, the middle plane 57 and the central plane 53 are the same, but alternatively the middle plane 57 may be angled relative to the central plane 53, wherein e.g. a plane angle between the middle plane and the central plane is at least 0 degrees and at most 90 degrees. Here, the first range sensor 51 and the second range sensor 52 are arranged back-to-back and directed away from the middle plane 57.
[0136] Still referring to figure 5, the first support element 561 and the second support element 562 are movable relative to one another. Namely, the separation angle 54 is adjustable from the initial separation angle 54 into an adapted separation angle 54’ by elastically deforming the support structure 16 from the initial state I into the adapted state II. In the adapted state II, the first support element 561 and the second support element 562 are reoriented relative to the middle plane 53. Here, the adapted separation angle 54’is smaller than the initial separation angle 54, and is 60 degrees. Alternatively, the separation angle may be enlarged.
[0137] The adapted state II is an elastically deformed state of the support structure 56. The first support element 561 is fixed on one end and connected to the second support element 562 on the other end, the first support element 561 and the second support element 562 are elastically deformable. The second support element 562 comprises an end that can be locked into a locking support structure. More specifically, the support structure 56 comprises a locking support structure comprising a locking mechanism 55. The locking support structure may for example be a slotted bar, and the locking mechanism 55 may for example be locking protrusions within said slotted bar. The end of the second support element 562 may be locked, or secured, or releasably fixed within said locking protrusions. This locks the support structure 56 in the elastically deformed state II. When the second support element 562 is released, due to the elastic deformation, the support structure 56 will deform back to the initial state I.
[0138] Yet alternatively, in other similar examples, the separation angle is adjustable from the initial separation angle into the adapted separation angle by folding the support structure from the initial state into the adapted state, the adapted state being a folded or unfolded state.
[0139] Yet alternatively, in other similar examples, the separation angle is adjustable from the initial separation angle into the adapted separation angle by sliding the support structure from the initial state into the adapted state.2024PF80489
[0140] 19
[0141] Figure 6 depicts schematically, by non-limiting example, an embodiment of a lighting system 600 according to the invention. The lighting system 600 comprises a luminaire 620 and a sensor module 610. The luminaire 620 comprises a light engine 621 and a housing 622. The light engine 621 is configured to emit light in operation. The sensor module 610 is releasably connected to said luminaire 620. More specifically, the housing 622 of the luminaire 620 comprises (a planar surface comprising a) planar slot 623. The sensor module 610 is at least partly arranged within the planar slot 623. The luminaire 620 conveys power and / or data signals to the sensor module 610.
[0142] Referring to figure 6, the sensor module 610 comprises a main body 615. The main body 615 comprises a central plane 61. The central plane 61 is perpendicular to the planar slot 623. The sensor module 610 comprises a first range sensor 611 having a first Field-of-View (FoVl) centered around a first main axis 6110. The sensor module 610 also comprises a second range sensor 612 having a second Field-of-View (FoV2) centered around a second main axis 6120. Here, the first range sensor 611 is a first Time of Flight (ToFl) sensor, and the second range sensor 612 is a second Time of Flight (ToF2) sensor, but may alternative be any other type of sensors.
[0143] The sensor module 610 further comprises a support structure 616. The support structure 616 comprises a first support element 6161 and a second support element 6162. The first range sensor 611 is mounted on the first support element 6161. the second range sensor 612 is mounted on the second support element 6162. The first support element 6161 and the second support element 6162 are arranged such that the first main axis 6110 and the second main axis 6120 are directed away from the planar slot 623. The first range sensor 611 and the second range sensor 612 are also arranged on opposite sides of a middle plane 63. Thereby, the first main axis 6110 and the second main axis 6120 are directed towards the middle plane 63.
[0144] Moreover, the middle plane 63 and the central plane 61 are angled. Namely, here, a plane angle (P) 62 between the central plane 61 and the middle plane 63 is +15 degrees (relative to the central plane 61). Hence, the support structure 616 comprising the support elements 6161, 6162 may be rotated relative to the main body 615.
[0145] Referring to figure 6, the first support element 6161 and the second support element 6162 are arranged such that a separation angle (a) 64 between the first main axis 6110 and the second main axis 6120 is at least 30 degrees and at most 150 degrees. The sensor module 610 and associated support structure 616 are depicted in an initial state (I).2024PF80489
[0146] 20
[0147] Here, said separation angle (a) 64 is depicted as 45 degrees. Other angles may be envisioned similarly.
[0148] Due to such an angled configuration, less space is occupied in the main body 615 of the sensor module 610. Therefore, albeit optionally, but depicted in figure 6, the main body 615 of the sensor module 610 comprises front surface 617 and a sensor slot 613. The front surface 617 is thereby arranged parallel to the planar slot 623 and facing away from the luminaire 620. The sensor slot 613 is arranged on the front surface 617. The support structure 616, the first range sensor 611, and the second range sensor 612, are at least partly arranged within the sensor slot 613. Moreover, albeit optional, the surface area of the sensor slot 613 is at most 40% of a total surface area of the front surface 617.
[0149] For example, albeit optionally, but depicted in figure 2 and figure 3, the sensor module 610 comprises a further sensor 618 for monitoring an ambient environment. For example, the further sensor 618 may be a different type of sensor compared to the first range sensor 611 and the second range sensor 612. Said further sensor 618 may for example be a single pixel thermopile, humidity sensor, temperature sensor, light sensor, sound pressure sensor, microphone, camera, PIR sensor, BLE receiver, Zigbee radio, IR receiver, thermopile array, TMOS sensor, radar, multi spectral sensor
[0150] Still referring to figure 6, in an embodiment, the support structure 616 is pivotable from the initial state (I) into a rotated state (II). Said rotated state (II) is depicted, by non-limiting example, in figure 7. In the rotated state (II), the plane angle 62 is adjusted from an initial plane angle 62 into a rotated plane angle 62’ by pivoting the support structure 616 from the initial state (I) into the rotated state (II), wherein the initial plane angle 62 and the rotated plane angle 62’ are at least 10 degrees different. Here, said rotated plane angle 62’ is -30 degrees (relative to the central plane 61).
[0151] In advanced embodiments, not depicted, the lighting system 600 as depicted in figures 6 and 7 may further comprise an adjustable support structure. Namely, the support structure is adaptable from an initial state into an adapted state, wherein the separation angle (a) is adjustable from an initial separation angle (a) into an adapted separation angle (a’) by adapting the support structure from the initial state into the adapted state; wherein in the adapted state the first support element and / or the second support element are reoriented relative to the middle plane 63. The sensor module may optionally comprise a visual indicator indicative of the separation angle.
[0152] Still referring to figures 6 and 7, albeit optionally, the sensor module 610 comprises an electronic circuit 618. The first range sensor 611 is configured to determine a2024PF80489
[0153] 21
[0154] first range input, and the second range sensor 612 is configured to determine a second range input. The electronic circuit 618 is configured to convey a signal indicative of the first range input and / or the second range input. Here, the electronic circuit is a wireless communication module. Yet even further, in embodiments, the lighting system 600 may comprise a (lighting) controller (not depicted) configured to obtain the signal indicative of the first range input and / or the second range input, wherein the controller is configured to control the light engine 621 of the luminaire based on the first range input and / or the second range input. The controller may e.g. be in the sensor module, the luminaire, or remote, separate and external to both the sensor module and the luminaire.
[0155] Figure 8 depicts schematically, by non-limiting examples, a sensor module 810 according to the invention. The sensor module 810 is depicted in an initial state (A) and in an adapted state (B).
[0156] The sensor module 810 is configured to be releasably mounted to a luminaire (not depicted). Said combination, i.e. luminaire with connected sensor module 810, may render a lighting system according to the invention. The sensor module 810 comprises a main body 815 and a connector 819. The main body 815 comprises a central plane 81. The connector 819 comprises a planar connector plane 823. The connector 819 is configured to connect the sensor module 810 to a (planar slot of a housing of) luminaire.
[0157] The sensor module 810 comprises a first range sensor 811 having a first Field of View (FoVl) centered around a first main axis 8110 and a second range sensor 812 having a second Field of View (FoV2) centered around a second main axis 8120. The sensor module 810 further comprises a support structure 816 comprising a first support element 8161 and a second support element 8162. The support structure 816 is connected to the main body 815. More specifically, albeit exemplary, the first support element 8161 and the second support element 8162 are mounted on a substrate 8100 that is mounted to the support structure 816, thereby the support structure 816 is connected to the main body 815 via the substrate 8100. The substrate 8100 may for example be a PCB.
[0158] Referring to figure 8, the first range sensor 811 is mounted on the first support element 8161 and the second range sensor 812 is mounted on the second support element 8162. The first support element 8161 and the second support element 8162 are arranged such that: (i) the first main axis 8110 and the second main axis 8120 are directed away from the planar connector plane 823; (ii) the first range sensor 8110 and the second range sensor 8120 are arranged on opposite sides of a middle plane 8; (iii) a separation angle 84, 84’ between the first main axis 8110 and the second main axis 8120 is at least 30 degrees and at most 1502024PF80489
[0159] 22
[0160] degrees. Here, said separation angle is 75 degrees in the initial state (A) of the sensor module 810, and 30 degrees in the adapted state (B) of the sensor module 810. The middle plane 83 is arranged at a plane angle relative to the central plane 81. Here, said plane angle is 0 degrees. Hence, the middle plane 83 and the central plane 81 are the same plane. Here, the first main axis 8110 and the second main axis 8120 are directed towards the middle plane 83.
[0161] More specifically, in the present embodiment, the first range sensor 811 is a first Time of Flight (ToFl) sensor, and the second range sensor 812 is a second Time of Flight (ToF2) sensor. Said Time of Flight sensors (ToFl, ToF2) may be operated individually (i.e. individual controllable), but also simultaneously, or alternately, or separately. Moreover, in the present embodiment, the first support element 8161 is a first lead frame comprising a first lead, and the second support element 8162 is a second lead frame comprising a second lead. The first lead and the second lead may be elastically or plastically deformable (e.g. bendable). Here, said leads are plastically deformable.
[0162] Still referring to figure 8, albeit optionally, the support structure 816 is adaptable from the initial state (A) into the adapted state (B), wherein in the adapted state the separation angle 84 is adjustable. Namely, the separation angle (a) 84 is adjustable from an initial separation angle (a) 84 of the initial state (A) into an adapted separation angle (a’) 84’ of the adapted state (B) by adapting the support structure 816 from the initial state (A) into the adapted state (B). Hence, in the adapted state (B), as depicted, the first support element 8161 and the second support element 8162 are reoriented relative to the middle plane 83. Since first support element 8161 and the second support element 8162 are lead frames with plastically deformable leads, the adapted state (B) will remain. Thus, the sensor module 810 according to the invention can easily and advantageously change the orientation of the first main axis 8110 and the second main axis 8120 so as to tailor the monitoring needs in a built environment.
[0163] Optionally, the sensor module may comprise a visual indicator indicative of the separation angle (i.e. initial or adapted separation angle). Optionally, the sensor module comprises at least one further sensor with a further sensor type different to a sensor type of the first range sensor and the second range sensor. Optionally, the first range sensor is configured to determine a first range input, and the second range sensor is configured to determine a second range input, wherein the sensor module comprises an electronic circuit configured to convey a signal indicative of the first range input and / or the second range input. Such an electronic circuit may e.g. be a wired or wireless communication circuit. Optionally, the sensor module may comprise a controller configured to obtain the signal indicative of the2024PF80489
[0164] 23
[0165] first range input and / or the second range input, and control an external device (e.g. said luminaire or any other device in the built environment) based on the first range input and / or the second range input.
[0166] Figure 10 depicts schematically, by non-limiting examples, a sensor module 1010 according to the invention. The sensor module 1010 depicted in figure 10 is similar to the sensor module 810 depicted in figure 8, but wherein the first support element 8161 and the second support element 8162 are positioned closer to one another (i.e. closer to the middle plane) in a substantially staggered in line configuration. Such an embodiment renders more miniaturization. Similarly, like in the embodiment depicted in figure 8, the support structure may be adaptable by adjusting (or: reorienting, or: deforming, or: bending) the first support element 8161 and the second support element 8162.
[0167] Figure 11 depicts schematically, by non-limiting examples, a sensor module 1110 according to the invention. The sensor module 1110 depicted in figure 11 is similar to the sensor module 810 depicted in figure 8, but wherein the support first support element 8161 and the second support element 8162 are positioned further from one another and back-to-back, wherein (different to the embodiment depicted in figure 8) the first main axis 8110 and the second main axis 8120 are directed away from the middle plane 83. Therefore, the separation angle (a) 1004 is also different in the embodiment depicted in figure 11.
[0168] Figure 11 depicts an initial state of the sensor module 1110 and associated support structure 816. However, figure 11 further depicts, in dotted lines, an adapted state of the sensor module 1110 and associated support structure 816. Namely, the support structure 816 is adaptable from an initial state into an adapted state. In the adapted state, the separation angle (a) 1004 is adjustable from an initial separation angle (a) 1004 into an adapted separation angle (a’) 1004’ by adapting the support structure 816 from the initial state into the adapted state (in dotted lines). Here, only the second support element 8162 is reoriented relative to the middle plane 83. This reorientation may be done by plastically deforming the second support element 8162’ in a deformed and adapted state, i.e. bending, relative to the middle plane 83. This renders the new separation angle 1004’. Such an adaptable sensor module is advantageous.
[0169] Figure 12 depicts schematically, by non-limiting examples, a sensor module 1210 according to the invention. The sensor module 1210 depicted in figure 12 is similar to the sensor module 810 depicted in figure 8, but wherein the support first support element 8161 and the second support element 8162 are positioned further from one another, wherein (different to the embodiment depicted in figure 8) the sensor module 1210 further comprises2024PF80489
[0170] 24
[0171] a third support structure 8163 comprising a third range sensor 813 having a third main axis 8130 centered around a third Field of View. Thereby, the third support structure is arranged between the first support element 8161 and the second support element 8162. Here the third support structure 8163 and associated third range sensor 813 are arranged perpendicular to the middle plane 83 (i.e. here, perpendicular to the central plane 81 and parallel to the planar connector plane 823). Hence, the third main axis 8130 is in the middle plane 83. Said support elements may be movable relative to one another. For example, said support elements may be pivotable or slidable relative to one another.
[0172] Figure 9 depicts schematically, by non-limiting examples, a lighting system 900 according to the invention. The lighting system 900 comprises a luminaire 920 and a sensor module 910. The luminaire 920 is not fully depicted. The luminaire 920 comprises a light engine (not depicted) and a housing 922. At part of the housing 922 is depicted. The housing 922 comprises a planar surface 922 comprising a planar slot 923. The sensor module 910 is at least partly arranged within the planar slot 923 and releasably connected to the luminaire 920. Said slot may e.g. be Fl slot, or a slot compliant with the Zhaga standard.
[0173] Referring to figure 9, the sensor module 910 comprises a main body 915 with a central plane 91. The sensor module 910 is depicted in an initial state. Here, the central plane 91 is also a middle plane 93. The central plane 91, hence the middle plane 93, is perpendicular to the planar slot 923 (hence the planar surface). Alternatively, in examples, a plane angle between the central plane and the middle plane may be at least 0 degrees and at most 90 degrees, such as e.g. at least 0 and at most 75 degrees.
[0174] The sensor module 910 comprises a first range sensor 911 having a first Field of View (FoVl) centered around a first main axis 9110; a second range sensor 912 having a second Field of View (FoV2) centered around a second main axis 9120; a third range sensor 913 having a third Field of View (FoV3) centered around a third main axis 9130; a fourth range sensor 914 having a fourth Field of View (FoV4) centered around a fourth main axis 9140. The first main axis 9110, the second main axis 9120, the third main axis 9130, and the fourth main axis 9140 are all directed away from the planar slot 923 to which the sensor module 910 is mounted. Said range sensors 911, 912, 913, 914 may for example be Time of Flight sensors.
[0175] The sensor module 910 further comprises a support structure 916. The support structure 916 is connected to the main body 915. The support structure 916 comprises a first support element 9161, a second support element 9162, a third support element 9163 and a fourth support element 9164. Other number of N support elements may be envisioned,2024PF80489
[0176] 25
[0177] wherein said number N is > 2. For example, a support structure may comprise a number of N = 6 support elements, wherein each is arranged on a respective side of a hexagon. Hence, for each number of N support elements, each support element may be arranged on a respective side of an N-sided polygon.
[0178] Still referring to figure 9, the first range sensor 911 is mounted on said first support element 9161. The second range sensor 912 is mounted on said second support element 9162. The third range sensor 913 is mounted on said third support element 9163. The fourth range sensor is mounted on said fourth support element 9164.
[0179] According to the present invention, the first support element 9161 and the second support element 9162 are arranged, or configured, on opposite sides of the middle plane 93. Thereby, in the present example, the first main axis 9110 and the second main axis 9120 are directed towards the middle plane 93. In alternative examples, the first main axis and the second main axis may be directed away from the middle plane. Moreover, the first support element 9161 and the second support element 9162 are arranged, or configured, such that the first main axis 9110 and the second main axis 9120 are under a separation angle (a) 94, wherein said separation angle (a) 94 between the first main axis 9110 and the second main axis 9120 is at least 30 degrees and at most 150 degrees. Here, said separation angle (a) 94 is for example depicted as 30 degrees.
[0180] According to the present invention, the third support element 9163 and the fourth support element 9164 are arranged, or configured, on opposite sides of a further middle plane 99. The further middle plane 99 is orthogonal to, or perpendicular to, the middle plane 93. Thereby, in the present example, the third main axis 9130 and the fourth main axis 9140 are directed towards the further middle plane 99. In alternative examples, the third main axis and the fourth main axis may be directed away from the further middle plane. Moreover, the third support element 9163 and the fourth support element 9164 are arranged, or configured, such that the third main axis 9130 and the fourth main axis 9140 are under a further separation angle (0) 98, wherein said further separation angle (9) 98 between the third main axis 9130 and the fourth main axis 9140 is at least 30 degrees and at most 150 degrees. Here, said further separation angle (9) 98 is for example depicted as 60 degrees.
[0181] In an embodiment, not depicted, the support structure of the embodiment depicted in figure 9 is adaptable from said initial state into an adapted state. In the adapted state, the separation angle (a) and / or the further separation angle are adjusted by reorienting the first support element, the second support element, the third support element, and / or the fourth support element (relative to the middle plane and the further middle plane,2024PF80489
[0182] 26
[0183] respectively). Thereby, the separation angle and the further separation angle may be at least 10 degrees different in the adapted state compared to the initial state. Moreover, in aspects, the support structure is adapted by plastically and / or elastically deforming the first support element, the second support element, the third support element, and / or the fourth support element (relative to the middle plane and the further middle plane, respectively).
