[0003] Optical patterns for improving lighting systems
[0004] FIELD OF THE INVENTION
[0005] The invention relates to lighting systems comprising at least one optical pattern. The invention further relates to a luminaire comprising at least one optical pattern. The invention further relates to methods associated with determining such optical pattern(s).
[0006] BACKGROUND OF THE INVENTION
[0007] Accessing information via optical patterns is well known in the art. Barcodes are common. Optical patterns may alternatively be phrased as optical codes. For example, a Quick Response (QR) code is a two-dimensional matrix barcode featuring colored squares on a differently colored background with fiducial markers. Such QR codes are readable by imaging devices (or: scanners) such as cameras. The QR codes contain information, typically metadata, and / or an identifier, and / or a link to a (e.g. online) database.
[0008] Hence, it is also known to provide optical patterns on lighting system components, so as to identify components, and to access and retrieve information.
[0009] However, for the purpose of safety and security, though physically present on a component, it may be undesired that optical patterns are (always) publicly available. It may be desired that only qualified personnel may read such codes, within specific contexts, and only at specific instances in time.
[0010] For example, for a lighting system, access to information may only be desired at installation, for commissioning, during service, and / or disposal - and not during use. This may prevent unauthorized actors to e.g. retrieve lighting system metrics and / or access lighting control settings. For example, during such specific instances in time, it may also be desired for qualified personnel to obtain more, tailored, or different information about the lighting system. Moreover, for example, the ability to receive information about the lighting system may depend on contractual agreements with relevant parties, such as a warranty period between the supplier and proprietor of the lighting system, and may need to be controlled accordingly, even though optical patterns may still be physically accessed. It may be relevant to fulfill such desires and needs.2025PF80083
[0011] 2
[0012] Furthermore, considering more and more lighting systems may start utilizing optical patterns, it may be desired that the information provided by the optical patterns and associated with the lighting system may remain consistent throughout use. This may be a problem for Solid State Lighting (SSL) lighting solutions, such as Light Emitting Diode (LED) or Laser Diode (LD) based lighting. Namely, due to the large-scale adoption of Light Emitting Diode (LED) lighting, the product lifetime of luminaires and lighting systems has significantly increased. For example, it is not uncommon for luminaires to have a lifetime of 15 to 20 years. Such luminaires may even be operated longer, but at decreased light output.
[0013] Consequently, due to such longer product lifetimes, especially for outdoor luminaires and lighting systems, lighting components with a shorter lifespan than the LED light engine may be replaced and / or serviced throughout the total lifetime of the luminaires and lighting systems. The optical patterns (e.g. arranged on components) may also not remain consistent throughout use, and degrade over time because of weather, ambient conditions, harsh operational conditions, and / or vandalism. This may lead to worn out, or unreadable optical patterns, or not sufficiently readable, thereby losing (part of) their function. For example, a QR sticker may worn out due to harsh conditions, or a painted QR code may fade (and partly disappear) due to exposure to light.
[0014] The present application provides solutions mitigating the above-mentioned problems and disadvantages, meeting the long-felt needs and desires, and rendering improved devices, systems and methods comprising at least one optical pattern in the field of lighting.
[0015] WO2024 / 227611 Al discloses a luminaire comprising a driver with a service tag.
[0016] SUMMARY OF THE INVENTION
[0017] The present invention is set out in the appended independent claims and dependent claims.
[0018] 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 for providing, in operation, luminaire light; wherein the luminaire comprises: a luminaire housing; a luminaire structure comprising a first structure surface; a first optical pattern configured to provide access to first system information and / or to trigger a first system action, wherein the first optical pattern is arranged within the luminaire housing; a first luminaire component arranged within the luminaire housing and releasably mounted to the first structure surface, wherein the first luminaire2025PF80083
[0019] 3
[0020] component comprises a first mounting surface, wherein the first luminaire component is an electrical component; wherein, when the first luminaire component is mounted to the first structure surface, the first mounting surface faces the first structure surface such that the first optical pattern is visually inaccessible and unreadable by an imaging device.
[0021] In an embodiment, the lighting system according to the invention is provided, wherein, when the first luminaire component is mounted to the first structure surface, the first optical pattern is arranged between the first structure surface and the first mounting surface; wherein the first optical pattern is arranged (i) on the first structure surface OR arranged (ii) on the first mounting surface.
[0022] Alternatively, in an embodiment, the lighting system according to the invention is provided, wherein the first luminaire component comprises a first side surface, wherein the first side surface is different to the first mounting surface, wherein the first side surface is angled to the first mounting surface, wherein the first optical pattern is arranged between a surface of the luminaire housing and the first side surface; wherein the first optical pattern is arranged (iii) on the first side surface OR arranged (iv) on the surface of the luminaire housing.

[0023] Hence, the lighting system and / or luminaire according to the present invention comprises a first optical pattern that is visually inaccessible when the first luminaire component is mounted to the first structure surface. The first optical pattern may only be accessed when said first luminaire component is unmounted and released. The fact that the first optical pattern may be read provides information about the mounted state of the component when the first optical pattern is being read. This renders additional information about the mounted state of the first luminaire component upon reading the first optical pattern. Moreover, the first system information conveyed via the first optical pattern, and / or the first system action triggered by reading the first optical pattern, may be associated with the unmounted (physically released) state of the first luminaire component. For example, said information and / or action may be related to installation, service and / or disposal. Since the first system information and / or the first system action may be related to such specific instances, it may be advantageous to render the first optical pattern visually inaccessible when the first luminaire component is still mounted.

[0065] 10
[0066] As partly mentioned, it is not uncommon for luminaires to have a relatively long product lifetime. Consequently, due to such longer product lifetimes, especially for outdoor luminaires, the optical patterns may degrade over time due to environmental and operational conditions, such as heat, temperature changes, radiation, dust and light. This may lead to the disadvantageous situation that such optical patterns may not be readable, or not sufficiently readable, thereby losing their function. This may particularly be true for optical patterns that are mounted adjacent to surfaces emitting such radiation.

[0084] 12
[0085] DETAILED DESCRIPTION
[0086] Figure 1 depicts schematically, by non-limiting example, an embodiment of a lighting system according to the invention.
[0087] The lighting system 1000 comprises a light generating device 1010, a first location 1001 and a second location 1002. Said light generating device 1010 may be a luminaire. Said first location 1001 may be a first surface. Said second location 1002 may be a second surface. The first location 1001 and the second location 1002 are thereby both on the same lighting generating device, but spatially separated and arranged on different surfaces of the light generating device 1010. In examples, said first surface may either be perpendicular to the second surface, or be opposite and parallel to the second surface. Alternatively, the light generating part may comprise a device surface comprising both the first location and the second location, but spatially separated by a separation distance, said separation distance being between 12 centimeters and 300 centimeters.
[0088] The first location 1001 comprises a first optical pattern 1011 providing first information 1021. The second location 1002 comprises a second optical pattern 1012 providing second information 1022. Such optical patterns may be optical codes. For example, the first optical pattern and the second optical pattern may be Quick Response (QR) codes. The first information 1021 comprises or provides access to a first part 1031 of system information 1030. The second information 1022 comprises or provides access to a second part 1032 of system information 1030. The first part 1031 and the second part 1032 are at least partially non-overlapping. The first part 1031 and the second part 1032 may thus have a common overlapping part, but always have a non-overlapping part. Such a common overlapping part may for example be a unique identifier. The system information 1030 is associated with the lighting system 1000 and / or the light generating device, or with a same component of the light generating device.
[0089] Said system information 1030 may for example be one or more of: product information, historic information, maintenance information, location information, and access information. Moreover, in embodiments, the first information 1021 comprises or provides access to a first encoding, and wherein the second information 1022 comprises or provides access to a second encoding. The first information may for example be an encoded link linking to the first part of the system information. The second information may for example be an encoded link linking to the first part of the system information.
[0090] Hence, the lighting system 1000 according to the embodiment of figure 1 enables a single light generating device 1010 to provide two different optical patterns at two2025PF80083
[0091] 13
[0092] different physically separated locations, wherein each provides access to at least partially non-overlapping parts 1031, 1032 of the system information. This facilitates accessing relevant parts of the system information, while enabling that part of the system information may still be overlapping.
[0093] For example, the first optical pattern may be at a first location on a first component, while the second optical pattern may be at a second location on a second component, each of said components having a different replacement or disposal manual. The first optical pattern may provide first information - e.g. a first QR code - providing access to a first part of system information, the first part of system information being the burned hours of the light generating device, the deterioration level of the first component, and a replacement or disposal manual for the first component. Similarly, the second optical pattern may provide second information - e.g. a second QR code - providing access to a second part of system information, the second part of system information being the (same) burned hours of the light generating device, the deterioration level of the second component, and a replacement or disposal manual for the second component. Because reading both QR codes provide access to the same burned hours of the light generating device, but also to unique information associated with each of the individual components, the first part and the second part of the system information are partially non-overlapping. Hence, the present invention improves the ergonomic use of information conveyed by optical patterns, such as QR codes, within the domain of lighting.
[0094] Figure 2 depicts schematically, by non-limiting example, an embodiment of a luminaire component 2000 according to the invention. The luminaire component 2000 is an electrical component and comprises a mounting surface 2001 and an optical pattern 2002. The optical pattern 2002 is arranged on the mounting surface 2001, such that when the luminaire component 2000 is mounted, the optical pattern 2002 will be visually inaccessible. Namely, the luminaire component 2000 comprises mounting means 2003 suitable for mounting the luminaire component to a surface of a luminaire. When the luminaire component is mounted to the surface of the luminaire, the first mounting surface faces - and optionally abuts - the surface of the luminaire. Hence, when this particular luminaire component is mounted, the optical pattern will always be hidden, or visually inaccessible, or unreadable by an imaging device suitable to read said optical pattern. According to the invention, the optical pattern is configured to provide access to system information and / or to trigger a system action. The system information and the system action are characterized in that the system information and the system action are purposefully associated a non-2025PF80083
[0095] 14
[0096] operational and / or non-mounted state of the luminaire component 2000. Namely, the system information may for example be one of: an installation guide for the luminaire component and / or a further luminaire component suitable for replacing the luminaire component; a disposal guide for the luminaire component; a (initial) configuration manual or (initial) configuration settings. The system action may for example be one of: a diagnostics check, a reset command, a shutdown, identifying a dissembled state; entering the lighting system and / or the luminaire in an emergency mode. Other information and actions may be envisioned similarly.
[0097] All in all, the luminaire component according to the invention advantageously enables that the optical pattern (is hidden / shielded and) cannot be read when mounted to the luminaire, and can only be read when purposefully unmounted, or in an unmounted state. This prevents unauthorized actors to access the optical pattern and the information associated therewith while the component is part of the luminaire assembly and is for example part of its operation. The relevant information is only accessible if the luminaire component is unmounted. For example, when unmounted, the (hidden) optical pattern becomes visually accessible and readable, and the information accessed via the optical pattern provides purposefully disposal or recycling information. Similar use cases may be envisioned accordingly.
[0098] Still referring to figure 2, said mounting means may be common fasteners and mounting techniques used to mount luminaire components to a luminaire. Here, the mounting means 2003 are screw holes. Alternatively, the mounting means may be at least one of:
[0099] (screw) holes, Velcro, an adhesive strip, a standardized connector, a press-fit connector, a snap-fit connector, a clamp, a magnet, etc. Still referring to figure 2, the optical pattern 2002 may be adhered, printed, etched, sketched, painted, pressed, cut, onto / into the mounting surface. Said optical pattern may e.g. be a quick-response (QR) code. Said optical pattern may e.g. be a sticker comprising a QR code.
[0100] Figure 3 depicts schematically, by non-limiting example, an embodiment of a method 3000 according to the invention. The method 3000 is performed by a lighting system according to the invention. The lighting system comprises a luminaire, an imaging device, and a system controller. The luminaire comprises a luminaire housing, a luminaire structure comprising a first structure surface, a first optical pattern arranged within the luminaire housing, and a first luminaire component arranged within the luminaire housing and comprising a first mounting surface. The method 3000 comprises a step 3001 of mounting the luminaire component to the first structure surface, wherein the first mounting surface2025PF80083
[0101] 15
[0102] faces the first structure surface (and optionally abuts the first structure surface), such that the first optical pattern is visually inaccessible and unreadable by an imaging device. The first optical pattern may for example be visually inaccessible and unreadable by an imaging device, if the imaging device cannot establish a line-of-sight to the first optical pattern that is suitable for successfully reading the first optical pattern. For example, QR codes cannot be read with an imaging device viewing the QR code under a certain angular range, and cannot be read with an imaging device that is too close to the QR code (in that the imaging device cannot focus).
[0103] The method further comprises the step 3002 of unmounting the first luminaire component from the first structure surface, such that the first optical pattern is visually accessible and readable by an imaging device.
[0104] The method further comprises the step 3003 of the imaging device reading the first optical pattern and accessing first system information upon reading the first optical pattern. The imaging device may e.g. be a computing device with a camera. Said computing device may e.g. be a smartphone, a tablet, a camera, a scanner, smart glasses. Said first system information may e.g. be visualized on a user interface. For example, the imaging device may optionally comprise a user interface for visualizing the (accessed) first system information.
[0105] Said first system information may for example be one or more of: product information, historic information, maintenance information, location information, and access information. More specifically, according to the invention, the first system information is purposefully associated to a non-operational and / or non-mounted state of the first luminaire component. For example, the first system information may be one of: an installation guide for the luminaire component and / or a further luminaire component suitable for replacing the luminaire component; a disposal guide for the luminaire component; a (initial) configuration manual or (initial) configuration settings.
[0106] Additionally, or alternatively, the method comprises the step 3004 of the imaging device reading the first optical pattern and conveying a trigger signal to the system controller upon reading the first optical pattern (and e.g. based on the first optical pattern), wherein the trigger signal is configured to trigger the system controller to perform the first system action. Hence, the method comprises a step 3005 of the system controller performing the first system action.
[0107] The first system action may for example be at least one of: a diagnostics check of the lighting system and / or the luminaire, a reset of the lighting system and / or the2025PF80083
[0108] 16
[0109] luminaire, a reconfiguration of the lighting system and / or the luminaire, a shutdown of the luminaire, identifying or assigning a status to the luminaire, entering the lighting system and / or the luminaire in a commissioning mode, adding the luminaire to a group.
[0110] Such a method may mutatis mutandis apply for a second optical pattern arranged within the luminaire housing, that is visually inaccessible when a second luminaire component is mounted. The second optical pattern may provide access to second system information, or trigger a second system action, which may mutatis mutandis be similar to the first system information and the first system action. In some examples, the first optical pattern may provide access to first system information, whereas the second optical pattern triggers a second system action. Hence, only when a second luminaire component is unmounted, and the second optical pattern is visually accessible, then a second system action is triggered, whereas when only a first luminaire component is unmounted, and the first optical pattern is visually accessible, then only access to system information is provided (and no triggered action).
[0111] Figure 4 depicts schematically, by non-limiting example, an embodiment of a lighting system 4000 according to the invention.
[0112] The lighting system 4000 comprises a luminaire 4400. The luminaire 4400 is configured to provide, in operation, luminaire light. Said luminaire 4400 comprises a luminaire housing 4440, a first optical pattern 4410, a luminaire structure 4444, and a first luminaire component 4430. The first optical pattern 4410 may be unique, such as a unique code. Said luminaire 4400 may for example be an outdoor luminaire, such as e.g. a streetlamp, or an indoor luminaire, such as e.g. a ceiling lamp.
[0113] Hence, said luminaire 4400 comprises a luminaire structure 4444. The luminaire structure comprises a first structure surface 4441. The luminaire structure 4441 may be part of the luminaire housing 4440, for example be an optical element, or a module, a plate, a latch, a bracket, a lip, a baffle, etc. Alternatively, said luminaire structure may be a further luminaire component. Said luminaire structure may alternatively be a support structure.
[0114] Said first luminaire component is an electrical (or: electronical) component, namely a (lighting) driver, but may alternatively be one of a controller, a communication module, a light engine, and an optical element. Moreover, the first luminaire component 4430 is arranged within the luminaire housing 4440 and releasably mounted to the first structure surface 4441. Said mounting may be via commonly known fastening means. The first luminaire component 4430 thereby comprises a first mounting surface 4431. Here, albeit not2025PF80083
[0115] 17
[0116] necessarily, the first luminaire component 4430 is mounted to the first structure surface via the first mounting surface 4431. For explanatory reasons, figure 4 depicts space between the first mounting surface 4431 of the first luminaire component 4430 and the first structure surface 4441 of the luminaire structure 4444, but as mentioned the first luminaire component 4430 is mounted to the first structure surface via the first mounting surface 4431. Albeit not necessary, when the first luminaire component 4430 is mounted to the first structure surface 4441, the first mounting surface 4431 abuts the first structure surface 4441.
[0117] The first optical pattern 4410 is arranged within the luminaire housing 4440 as well. The first optical pattern 4410 provides, or provides access to, first system information and / or triggers a first system action. Said first optical pattern 4410 is for example a Quick-Response (QR) code. The first optical pattern 4410 may for example be implemented as a tag, a sticker, a print, a stamp, etc. Other visual patterns and / or visual codes may be envisioned similarly. Namely, in the present embodiment, the first optical pattern 4410 is arranged between the first structure surface 4441 and the first mounting surface 4431. For example, the first optical pattern 4410 may be arranged on the first structure surface 4441 or on the first mounting surface 4431. Here, it is arranged on the first structure surface 4441.
[0118] Moreover, for example, the first optical pattern 4410 itself may encode first system information, or encode a link to access first system information, whereas scanning (or: reading) the first optical pattern may additionally or alternatively trigger a first system action, e.g. associated with the lighting system, the luminaire, the first component, and / or the luminaire structure.
[0119] Still referring to figure 4, the first luminaire component 4430 is mounted to the first structure surface 4441, and when the first luminaire component 4430 is mounted to the first structure surface 4441, the first mounting surface 4431 faces the first structure surface 4441 such that the first optical pattern 4410 (i.e. the QR code) is visually inaccessible. More specifically, here, when the first luminaire component 4430 is mounted to the first structure surface 4441, the first mounting surface 4431 faces the first structure surface 4441 and the first optical pattern 4410 is visually inaccessible. For example, when the first luminaire component 4430 is mounted to the first structure surface 4441, the first mounting surface 4431 abuts the first structure surface 4441, and therefore the first optical pattern 4410 is not sufficiently visible and / or readable from the ambient. Hence, visually inaccessible may mean visually blocked, insufficiently visible, and / or unreadable for an imaging device, such as e.g. a smart device comprising a camera. In embodiments, throughout the application, a distance between the first structure surface and the first mounting surface may be at most 12025PF80083
[0120] 18
[0121] centimeters. Since a mounted first luminaire component, or even mounted with said distance, only enables very low angle to the line-of-sight to the first optical pattern, thereby rendering the first optical pattern (i.e. the QR code) to be unreadable when the first luminaire component is mounted (i.e. in mounted position).
[0122] In alternative embodiments, the first optical pattern is arranged on a component surface angled, or perpendicular, to the first mounting surface, and may therefore not face the first structure surface The first structure surface will therefore merely serve as a support for mounting the first luminaire component, while the first optical pattern on the component surface is visually inaccessible due to other surfaces blocking the view of the optical pattern. Said other surfaces may for example be the luminaire housing itself.
[0123] Alternatively, in an embodiment, not depicted, the first luminaire component comprises a first side surface, wherein the first side surface is different to the first mounting surface, wherein the first optical pattern is arranged on the first side surface; wherein, when the first luminaire component is mounted to the first structure surface, the first optical pattern faces the housing such that the first optical pattern is visually inaccessible.
[0124] The first system information comprises an installation guide for the first luminaire component and / or a second luminaire component suitable for replacing the first luminaire component, OR wherein the first system information comprises a disposal guide for the first luminaire component. Other system information may be envisioned similarly, and may be system information mentioned in this application.
[0125] Hence, referring to the lighting system as embodiment in figure 4, the first luminaire component 4430 is releasably mounted to the first structure surface 4444, wherein, when the first luminaire component 4430 is mounted to the first structure surface 4441, the first optical pattern 4410 is visually inaccessible. As a result, the luminaire 4000 according to the present invention comprises a first optical pattern 4410 that is visually inaccessible when the first luminaire component 4430 is mounted to the first structure surface 4441, and only becomes visually accessible when the first luminaire component 4430 is released, unmounted from the first structure surface 4441. Hence, the first optical pattern 4410 may only be accessed when said first luminaire component 4430 is released. Thereby, the fact that the first optical pattern 4410 can be read (or: scanned, or: imaged) is already offering the information that the first luminaire component 4430 may be released (from its mounted position). This enables that the first system information and / or triggering the first system action can only be accessed during specific instances wherein the first luminaire component 4430 is (physically) released, such as during installation, service and / or disposal, and not during (regular) use. For2025PF80083
[0126] 19
[0127] example, as partly mentioned, if the first visual pattern can be read, the first system information and / or the first system action may be associated with installation or disposal of the first luminaire component. Since the first system information and / or the first system action may be related to such specific instances, it may be advantageous to render the first optical pattern 4410 visually inaccessible when the first luminaire component 4430 is still mounted. Since only qualified personnel may be able to de-mount luminaire components, the first system information and / or the first system action may be related to activities associated with and for such qualified personnel, and not any rogue person attempting to read visual patterns of the luminaire. This is an advantageous safeguard.
[0128] Referring back to figure 4, in further embodiments, albeit optionally, the lighting system further comprises an imaging device 4500 configured to read the first optical pattern 4410. Such an imaging device may alternatively be phrased as a camera device, a user interface device, or a control device, or a commissioning device, or a scanner device. Such an imaging device may comprise a sensor, e.g. optical scanner, for scanning said first optical pattern. Said optical scanner may for example be a camera or a light diode.
[0129] As mentioned, the first optical pattern 4410 provides, or provides access to, first system information and / or triggers a first system action.
[0130] The imaging device 4500 according to the invention is configured to access the first system information upon scanning the first optical pattern 4410. For example, the first system information may comprise an installation guide for the first luminaire component 4430 and / or a second luminaire component suitable for replacing the first luminaire component 4430. Alternatively, the first system information comprises a disposal guide for the first luminaire component. When released, it may be disposed, and the optical pattern may facilitate this effort.
[0131] Referring to figure 4, in further embodiments, albeit optionally, the lighting system further comprises a system controller 4600. The system controller 4600 is configured to perform a system action. The imaging device 4500 is configured to convey a trigger signal to the system controller 4600 upon reading the first optical pattern 4410. The trigger signal is configured to trigger the system controller 4600 to perform the first system action. Here, the system action is a diagnostics check of the lighting system 4000, for example whether all components are installed or configured correctly. Alternatively, the system action may be at least one of: a diagnostics check of the lighting system and / or the luminaire, a reset of the lighting system and / or the luminaire, a reconfiguration of the lighting system and / or the2025PF80083
[0132] 20
[0133] luminaire, a shutdown of the luminaire, identifying or assigning a status to the luminaire. Other actions may be envisioned similarly, or may be as mentioned in this application.
[0134] Here, the luminaire 4400 comprises the system controller 4600. Alternatively, the imaging device comprises the system controller, or yet alternatively the system controller is a standalone apparatus physically separated and remote from the imaging device and the luminaire, such as for example a remote server, bridge device or database. Hence, in the latter, the luminaire and the imaging device are separate from the system controller.
[0135] In some embodiments, the luminaire structure comprises a locking mechanism, wherein the first electrical component is releasably mounted to said luminaire structure in a locked position via the locking mechanism. The locking mechanism may comprise one of: a clamping means, a press-fit connection, a magnet.
[0136] Figure 7 depicts schematically, by non-limiting example, an embodiment of a lighting system 7000 according to the invention. The lighting system 7000 is exactly the same as the lighting system 4000 as depicted in figure 4, but wherein the luminaire 7400 comprises a further optical pattern 7420 arranged within the luminaire housing 7440 and configured to provide access to further system information and / or trigger a further system action, and wherein the first optical pattern 7410 is arranged on the first mounting surface 7431 (hence on the first luminaire component 77430) instead of the first structure surface 7441.
[0137] Moreover, the first luminaire component 7430 comprises a first side surface 7433 different to the first mounting surface 7431. Here, the first side surface 7433 is perpendicular to the first mounting surface 7431. The further optical pattern 7420 is arranged between a surface of the luminaire housing 7440 and the first side surface 7433. Here, the further optical pattern 7420 is arranged on the side surface 7433 of the first luminaire component 7430. Said phrasing ‘arranged on’ may alternatively be phrased as ‘mounted on’, or ‘sticked on’, or ‘painted on’, or ‘etched on’, or ‘pressed on’, or ‘cut on’.
[0138] More specifically, according to the present invention, when the first luminaire component 7430 is mounted to the first structure surface 7441, the first optical pattern 7410 and the further optical pattern 7420 are both (hidden from view and) visually inaccessible and unreadable by an imaging device. Hence, the positioning, mounting, and placement of the first luminaire component 7430 according to the present invention hides both optical patterns 7410, 7420 accordingly. Both optical patterns 7410, 7420 may only be read by unmounting the first luminaire component 7430. The first optical pattern 7410 is configured to provide access to first system information and / or trigger a first system action, while the further2025PF80083
[0139] 21
[0140] optical pattern 7420 is configured to provide access to further system information and / or trigger a further system action. Said first system information and said further system information may be at least partly non-overlapping. Reading said first system information and said further system information within period of time may provide third system information or trigger a third system action. The third system information may be different from the first system information and the further system information. The third system action may be different from the first system action and the further system action.
[0141] Figure 5 depicts, by non-limiting example, an embodiment of a lighting system 5000 according to the invention. The lighting system 5000 is similar to the lighting system 4000 as depicted in figure 4, but wherein the current lighting system 5000 further comprises a second optical pattern 5410 configured to provide access to second system information and / or to trigger a second system action.
[0142] More specifically, the lighting system 5000 depicted in figure 5 comprises a luminaire 5400. The luminaire 5400 is configured to provide, in operation, luminaire light. Said luminaire 5400 comprises a luminaire housing 5440. The luminaire housing is at least partly non-transparent. The luminaire 5400, and here optionally the luminaire housing, comprises a luminaire structure 5444 according to the invention. The luminaire structure 5444 comprises a first structure surface 5441 and a second structure surface 5442. The luminaire 5400 further comprises a first optical pattern 5410 and a second optical pattern 5420. The first optical pattern 5410 and the second optical pattern 5420 are different and unique.
[0143] Furthermore, the first luminaire component 5430 is an electrical component, namely a lighting driver, but may alternatively be one of a controller, a communication module, and an optical element. The first luminaire component is therefore void of a solid-state light source. The second luminaire component 5450 is an electrical component, namely a light engine, but may alternatively be one of a controller, a communication module, a driver. The second luminaire component comprises therefore a solid-state light source. Said solid-state light source renders at least part of the luminaire light. In some alternative examples, the first luminaire component and the second luminaire component are both having, or are both void of, a solid-state light source.
[0144] The first luminaire component 5430 comprises a first mounting surface 5431 and a first side surface 5432. The first side surface 5432 is angled relative to, and here perpendicular to, the first mounting surface 5431. The second luminaire component 5450 comprises a second mounting surface 5451.2025PF80083
[0145] 22
[0146] Moreover, the first luminaire component 5430 is arranged within the luminaire housing 5440 and releasably mounted to the first structure surface 5441, whereas the second luminaire component 5450 is arranged within the luminaire housing 5440 and releasably mounted to the second structure surface 5442. Said mounting may be via commonly known fastening means.
[0147] Here, albeit not necessarily, the first luminaire component 5430 is mounted to the first structure surface 5441 via the first mounting surface 5431, and the second luminaire component 5450 is mounted to the second structure surface 5442 via the second mounting surface 5451. In some examples, the luminaire structure comprises a single surface comprising the first mounting surface and the second mounting surface, wherein the first mounting surface and the second mounting surface are the same single surface.
[0148] The first optical pattern 5410 and the second optical pattern 5420 are arranged within the luminaire housing 5440. The first optical pattern 5410 provides, or provides access to, first system information and / or triggers a first system action. Said first optical pattern 5410 is for example a Quick-Response (QR) code. The second optical pattern 5420 provides, or provides access to, second system information and / or triggers a second system action. Said second optical pattern 5420 is for example a Quick-Response (QR) code. Such optical patterns may for example be implemented as a tag, a sticker, a print, a stamp, etc. Other visual patterns and / or visual codes may be envisioned similarly. Said first system information and said second system information are at least partially non-overlapping, and / or wherein said first system action and said second system action are different.
[0149] Namely, in the present embodiment, the first optical pattern 5410 is arranged between the housing 5440 and the first side surface 5433. The second optical pattern 5420 is arranged between the second structure surface 5442 and the second mounting surface 5451. The first optical pattern 4410 is thereby arranged on the first side surface 5433. The second optical pattern 5420 is arranged on the second mounting surface 5451.
[0150] According to the present invention, when the first luminaire component 5430 is mounted to the first structure surface 5441, the first mounting surface face 5431 faces the first structure surface 5441 such that the first optical pattern 5410 is visually inaccessible. Namely, the first luminaire component 5430 is mounted such that the first optical pattern 5410 on the side surface 5433 of the first luminaire component 5430 is adjacent and substantially flush to the luminaire housing, such that (due to this purposefully mounting of the first luminaire component 5430) the first optical pattern 5410 is hidden from (plain) view.2025PF80083
[0151] 23
[0152] Moreover, according to the present invention, when the second luminaire component 5450 is mounted to the second structure surface 5442, the second mounting surface 5451 faces the second structure surface 5442 such that the second optical pattern 5410 is visually inaccessible. Since none of the visual patterns are visible from the outset, only the visual patterns of the luminaire components that are un-mounted, or detached, are able to be read. This prevents unauthorized, public and erroneously reading of such visual patterns, and only enables qualified and authorized personnel to read the visual patterns of the components of the luminaire of the lighting system.
[0153] Referring back to figure 5, in further embodiments, albeit optionally, the lighting system 5000 further comprises an imaging device 5500 configured to scan the first optical pattern 5410 and the second optical pattern 5420. Such an imaging device may alternatively be phrased as a camera device, a user interface device, or a control device, or a commissioning device, or a scanner device. Such an imaging device may comprise a sensor, e.g. optical scanner, for scanning said first optical pattern. Said optical scanner may for example be a camera or a light diode.
[0154] As mentioned, the first optical pattern 5410 provides, or provides access to, first system information and / or triggers a first system action, and the second optical pattern 5420 provides, or provides access to, second system information and / or triggers a second system action.
[0155] The imaging device 5500 according to the invention is configured to access the first system information upon scanning the first optical pattern 5410, and access the second system information upon scanning the second optical pattern 5420. For example, the first system information may comprise an installation guide for the first luminaire component 5430 and / or a further luminaire component suitable for replacing the first luminaire component 5430. Alternatively, the first system information comprises a disposal guide for the first luminaire component. When released, it may be disposed, and the optical pattern may facilitate this effort. Similarly, the second system information may comprise an installation guide for the second luminaire component 5450 and / or a further luminaire component suitable for replacing the second luminaire component 5450. Alternatively, the second system information comprises a disposal guide for the second luminaire component.
[0156] Referring to figure 5, in further embodiments, albeit optionally, the lighting system further comprises a system controller 5600. The system controller 5600 is configured to perform a system action. The scanner device 5500 is configured to convey a first trigger signal to the system controller 5600 upon scanning the first optical pattern 5410 and / or a2025PF80083
[0157] 24
[0158] second trigger signal upon scanning the second optical pattern 5420. The first trigger signal is configured to trigger the system controller 5600 to perform the first system action and / or the second trigger signal is configured to trigger the system controller 5600 to perform the second system action. Here, both system actions are a diagnostics check of the lighting system 5000, for example whether all components are installed or configured correctly. Alternatively, the system action may be at least one of a diagnostics check of the lighting system and / or the luminaire, a reset of the lighting system and / or the luminaire, a reconfiguration of the lighting system and / or the luminaire, a shutdown of the luminaire, identifying or assigning a status to the luminaire. The first system action, and / or the second system action may comprise the action of raising a flag that a luminaire component is unmounted. Here, the system controller is separate from the scanner device and the luminaire. The system controller is for example a remote server or a bridge device.
[0159] Figure 6 depicts schematically, by non-limiting example, a lighting system 6000 according to the invention. The lighting system 6000 comprises a luminaire 6400. The luminaire 6400 comprises a luminaire housing 6440 and a luminaire structure 6444 comprising a first structure surface 6441. The luminaire structure 6444 may be a plate. The luminaire 6400 further comprises a first luminaire component 6430 and a second luminaire component 6470. Both components 6430, 6470 may be electronic components. For example, the first luminaire component 6430 may be a driver, and the second luminaire component 6470 may be a communication module. Both components may alternatively be the same type of component.
[0160] The first luminaire component 6430 comprises a first mounting surface 6431 and a second structure surface 6432. Here, the second structure surface 6432 of the first luminaire component 6430 is parallel and opposite to the first mounting surface 6431. Thus, said second structure surface 6432 may be a top surface of the first luminaire component 6430 whereas the first mounting surface 6431 may be a bottom surface thereof. The first luminaire component 6430 is arranged within the luminaire housing 6440 and releasably mounted to the first structure surface 6441 (with common fastening means).
[0161] The second luminaire component 6470 comprises a second mounting surface 6471 and is arranged within the luminaire housing 6440 and releasably mounted to the second structure surface 6432 of the first luminaire component 6430. Hence, the second luminaire component 6470 is secured to the first luminaire component 6430.
[0162] Referring to figure 6, the luminaire 6400 comprises a first optical pattern 6410 and a second optical pattern 6420 arranged within the luminaire housing 6440. The first2025PF80083
[0163] 25
[0164] optical pattern is configured to provide access to first system information and / or to trigger a first system action. The second optical pattern is configured to provide access to second system information and / or to trigger a second system action. The first system information and the second system information are at least partly non-overlapping and / or different. The first system information and the second system information may be unique optical codes. Albeit optional, the first system action and the second system action may also be different. Here, the first optical pattern and the second optical pattern are quick response (QR) codes.
[0165] Still referring to figure 6, when the first luminaire component 6430 is mounted to the first structure surface 6441, the first mounting surface 6431 faces the first structure surface 6441 such that the first optical pattern 6410 is visually inaccessible and unreadable by an imaging device. More specifically, when the first luminaire component 6430 is mounted to the first structure surface 6441, the first optical pattern 6410 is arranged between the first structure surface 6441 and the first mounting surface 6431. The first optical pattern 6410 is namely arranged on the first mounting surface 6431.
[0166] Furthermore, when the second luminaire component 6470 is mounted to the second structure surface 6432 (and the first luminaire component 6430), the second mounting surface 6471 faces the second structure surface 6432 such that the second optical pattern 6420 is visually inaccessible and unreadable by an imaging device. More specifically, when the second luminaire component 6470 is mounted to the second structure surface 6432, the second optical pattern 6420 is arranged between the second structure surface 6432 and the second mounting surface 6471. The second optical pattern 6410 is namely arranged on the second mounting surface 6471.
[0167] Hence, the embodiment depicted in figure 6 provides examples of luminaire components 6430, 6470 that are stacked on top of each other, and due to such stacking their optical patterns (i.e. QR codes) become visually inaccessible. Only when unstacked, the respective optical patterns may be read. The first system information and the second system information may thus relate to installation, disposal, recycling, configuring of such luminaire components and / or the luminaire as such. The first system action, and / or the second system action may e.g. comprise the action of raising a flag that a luminaire component is unmounted.
[0168] Figure 8 depicts schematically, by non-limiting example, an embodiment of a luminaire 8000 according to the invention. The luminaire 8000 comprises a first location 8011, an electrical component 8030 configured to generate radiation 8080 in operation, and a first optical pattern 8010 configured to provide, or provide access to, first system information2025PF80083

[0170] and / or to trigger a first system action. The first optical pattern 8010 is arranged at the first location 8011. The first optical pattern is a QR code, e.g. a QR code sticker. The first location 8011 is physically remote from the electrical component 8030. The electrical component 8030 is a lighting driver, for example, or alternatively a light engine. Hence, said radiation 8080 is thermal radiation, i.e. heat. It may alternatively be light and / or electromagnetic radiation. Here, said luminaire comprises a luminaire housing 8040. The electrical component 8030 and the first optical pattern 8010 are arranged within the (same) luminaire housing 8040. Moreover, the first location 8011 is facing away from the electrical component 8030. Phrased differently, the first optical pattern 8010 is shielded from the radiation of emanating from the electrical component 8030. For example, the first location 8011 may be a first surface of the luminaire 8000, or an element / another component of the luminaire, facing away from the electrical component 8030. The first location and the electrical component may be in the same compartment of the luminaire. In an embodiment, the luminaire comprises a detachable substrate comprising the first location and a protective compartment, wherein the releasable substrate is attached to the protective compartment of the luminaire.
