METHOD AND SYSTEM FOR CONTROLLING A LIGHTING DEVICE

Description

[0001] The present invention relates to a method and a system for controlling a lighting device, in which lighting information about the illumination emitted by a lighting device and body data of a person located in the illumination area or in a predefined area of ​​the lighting device are recorded. Furthermore, the present invention relates to a method and a system for controlling a lighting device, in which body data of a person located in the illumination area or in a predefined area of ​​the lighting device are recorded.

[0002] In many different areas of lighting technology, such as industry, offices, schools / universities, and hospitals, light management or lighting control is becoming increasingly important. Increasingly, lighting is controlled differently, or switched on or off, depending on various factors. For example, daylight control or control based on presence detection is used to save energy. Daylight control can also be used to achieve the most consistent lighting conditions possible in a building or room throughout the day.

[0003] Another area in which light management or lighting control is becoming increasingly important is the effect of light on the well-being and productivity of people or those who are in the area of ​​​​corresponding lighting. It is already known that the type of light emission influences people's biorhythms. It is generally assumed that, for example, light with a higher blue content has a stimulating effect, while lower color temperatures have a more calming effect. By influencing people through the type of light emission, various advantages can be achieved in different application areas. For example,In industry it is conceivable that the light has a stimulating effect, resulting in fewer days off and higher productivity among employees; in offices it could achieve a greater sense of well-being and therefore higher productivity; in schools / universities it could have a stimulating effect and therefore better learning behavior; and in hospitals it could support the healing process and have a calming effect.

[0004] Several studies have already been conducted on the effects of light on people's well-being and productivity. However, their significance is questionable because only a relatively small number of test subjects were examined, as such studies are relatively complex. One reason for this is that a sample of people from different demographic backgrounds has to come to a laboratory and their physiological reactions have to be measured. Because of this effort, such studies are carried out with a limited number of people (a maximum of a few hundred people). In addition, physiological reactions such as stress, heart rate, etc. are influenced by a variety of factors, such as the mood of the day. Due to the small number of participants, it is hardly possible to cluster by age, gender, etc., even in studies known to date.

[0005] The significance of such studies is therefore rather low and only little useful information regarding optimal lighting control can be obtained from the studies.

[0006] Furthermore, it should be noted that dimming and color temperature gradients derived from such studies are rigidly stored in a system and cannot be adapted, for example, to local conditions. The system also receives no feedback on whether such gradients have a positive effect on the people concerned.

[0007] WO 2010 / 079388 A1 shows a controllable lighting network, wherein the lighting network is designed to change lighting based on the number of people, wherein it is further provided that the lighting network has means for detecting people, wherein furthermore based on the detected person the lighting can be changed according to previously stored preferred setting values ​​of the person.

[0008] US 2014 / 0052220 A1 describes a lighting system for triggering a change in the circadian state or well-being of a mammal. The lighting system comprises a controllable light source and a computing unit configured to receive and compare status information regarding the circadian state or well-being of the mammal and operating information from a light sensor, and to adjust the light source based on the comparison.

[0009] DE102012206691A1 relates to a street and path lighting system with a lighting device which has a projection unit for projecting signals onto a projection surface, and a communication module which is designed to control the projection unit on the basis of incoming input signals.

[0010] WO2013111134A1 shows a lighting device coupled to sensors or an image recording device and a logical control device, wherein the lighting device makes it possible to vary the lighting intensity and the lighting spectrum according to the changing needs of a user.

[0011] WO 1999056262A1 describes an automatic control system for actuators and safety devices in building automation. A wrist-worn sensor and transmitter unit repeatedly sends messages indicating the user's physiological state in the form of short telegrams to a receiving and control device located in a monitored room, either as a separate unit or as part of a device to be controlled.

[0012] DE202011108475U1 specifies an adaptive lighting system with a detection unit with which one or more extrinsic variables, i.e. variables occurring outside the adaptive lighting system, can be detected and transmitted to an evaluation and control unit, wherein the evaluation and control unit, with which a control signal can be generated from the transmitted extrinsic variables and transmitted to one or more adaptive light sources, and the one or more adaptive light sources, which are designed to vary one or more of their emission properties on the basis of the transmitted control signal.

[0013] Overall, the problem is that previous studies have hardly provided any reasonably usable guidelines for controlling lighting that would have a positive impact on the well-being and productivity of the majority of people.

[0014] The object of the present invention is to create a way to achieve positive effects through the impact of light on people's well-being and productivity.

[0015] The object is achieved by a method for controlling a lighting device according to claim 1 and a system for controlling a lighting device according to claim 6. Advantageous developments of the invention are the subject of the dependent claims.

[0016] According to the invention, a method and a system for controlling a lighting device are provided, in which lighting information about the illumination emitted by a lighting device and body data of a person located in the illumination area or in a predefined area of ​​the lighting device are recorded. The body data and lighting information recorded at a specific, identical time are associated with each other and transmitted to a data collection device. For this purpose, the system comprises at least one lighting device, at least one means for recording body data, and a data collection device.

[0017] Advantageously, it is provided that body data and lighting information are recorded at several different times and are assigned to each other and transmitted to the data collection device, wherein the lighting device can emit a different lighting at the different times.

[0018] Preferably, the body data of a plurality of people can be recorded using a plurality of means for recording body data, wherein each person is assigned a means for recording body data and the lighting information of the lighting device is in each case assigned to the body data of a person. Alternatively, a plurality of lighting devices can be provided, wherein the body data of the person is assigned to the lighting information of the lighting device in whose lighting area or predefined area the person is located. It is also possible for body data and lighting information of different people and a plurality of lighting devices to be recorded and assigned to one another and transmitted to the data collection device, wherein the body data of a person is assigned to the lighting information of the lighting device in whose lighting area or predefined area the person is located.predefined area the person is located.

[0019] Furthermore, it may also be provided that further information about the person, such as age or gender, is transmitted to the data collection facility.

[0020] Advantageously, the mutually associated body data and lighting information or the mutually associated body data and lighting information and the further information of the person are evaluated in such a way that information about the effect of the lighting of the lighting device on the well-being or productivity of the person is obtained, wherein the data collection device can be designed to evaluate the mutually associated body data and lighting information.

[0021] Preferably, the lighting device can be controlled depending on the information about the effect of the lighting and / or the acquired body data, wherein the data collection device can be designed to control the lighting device.

[0022] The invention also provides a method and a system for controlling a lighting device, in which body data of a person located in the lighting area or in a predefined area of ​​the lighting device are recorded, and the lighting device is then controlled depending on the recorded body data. For this purpose, the system comprises a lighting device and a means for recording body data.

[0023] Both in the method and the system for controlling a lighting device and in the method and the system for controlling a lighting device, the predefined area can be a sub-area of ​​the lighting area of ​​the lighting device, in particular a workplace.

[0024] Likewise, the method and system for controlling a lighting device can determine the position of the person, with the person's position being determined in particular based on whether the person is within the lighting area or predefined area of ​​the lighting device. The system for controlling a lighting device can have means for determining the person's position, which can be GPS means, RFID means, NFC means, or Bluetooth means.

[0025] Advantageously, it is then also provided that the body data or the body data and the lighting information are only recorded when the person is within the lighting area or predefined area of ​​the lighting device.

[0026] In the method and system for controlling a lighting device, it is preferably provided that the data collection device is located centrally in a building or building complex, for example, in the control center of a larger lighting system, or on the Internet, for example, in a cloud or on a manufacturer's server. Alternatively, the data collection device could also be located locally, for example, in a smartphone.

[0027] In the method and system for controlling a lighting device, it is preferably provided that the system has a central control device that is centrally located in a building or building complex, for example, in the control center of a larger lighting system, or on the Internet, for example, in a cloud or on a manufacturer's server. The system can be configured to transmit the body data acquired by the means for acquiring body data to the central control device, and the central control device can be configured to control the lighting device depending on the acquired body data.

[0028] In the system for controlling a lighting device, the means for acquiring body data preferably comprises a sensor, transmitting, and / or receiving unit for acquiring the body data, wherein the sensor, transmitting, and / or receiving unit is arranged in particular in an activity tracker, e.g., a bracelet or a wristwatch, or in a smartwatch. Additionally, a receiving and transmitting unit can also be provided, wherein the receiving and transmitting unit is arranged in particular in a smartphone. Furthermore, the sensor, transmitting, and / or receiving unit can be configured to transmit the acquired body data to the receiving and transmitting unit.

[0029] Preferably, the receiving and transmitting unit is designed to control the lighting device.

[0030] In the system for controlling a lighting device, the lighting device can be designed to transmit the lighting information to the sensor, transmitting and / or receiving unit or the receiving and transmitting unit, and the sensor, transmitting and / or receiving unit or the receiving and transmitting unit can be designed to assign the lighting information to the body data and to transmit the mutually assigned body data and lighting information to the data collection device or, via the receiving and transmitting unit, to the data collection device.

[0031] Alternatively, the lighting device can also be designed to transmit the lighting information to the data collection device, the sensor, transmitting and / or receiving unit or the receiving and transmitting unit can be designed to transmit the body data to the data collection device, and the data collection device can be designed to assign the transmitted body data to the transmitted lighting information.

[0032] In the system for controlling a lighting device, the means for determining the position can be arranged in or together with the sensor, transmitting and / or receiving unit or the receiving and transmitting unit.

[0033] The method according to the invention and the system according to the invention for controlling a lighting device make it possible to continuously obtain information about the effect of light on the well-being and productivity of people or persons during normal operation of a lighting device, wherein the proposed procedure allows corresponding data to be collected from a very large number of people.

[0034] Compared to previous studies, which typically included a maximum of a few hundred people, this allows a much larger sample size—several thousand or even several hundred thousand—to contribute to obtaining information about the impact of light on people's well-being and productivity. This allows the large sample size to reduce or eliminate certain confounding factors, such as the very specific daily mood of an individual or the potentially completely different reaction of one person to a particular type of light compared to many others.

[0035] It should be noted that the body data can include, for example, pulse, blood pressure, and perspiration, but also the user's movements, which are detected via MEMS gyroscopes or acceleration sensors. The body data is used in particular to record the person's reaction to emitted light or illumination from the lighting device. This means that by assigning body data to corresponding lighting information, it is possible to determine how a person reacts to a specific lighting situation or how this lighting situation affects the person in terms of well-being and productivity.

[0036] Furthermore, it should also be noted that corresponding data or information about the effect of lighting, which has been determined and evaluated by a method or system for controlling a lighting device, can also be used in lighting devices or corresponding systems that do not collect lighting information and body data. This can be achieved, for example, by a manufacturer determining and evaluating corresponding data or information about the effect of lighting using a method or system for controlling a lighting device and then using this data in lighting devices or corresponding systems that do not collect lighting information and body data.

[0037] The method and system according to the invention for controlling a lighting device make it possible to control the lighting device accordingly depending on recorded body data, i.e. depending on the well-being or productivity of a person. In this case, it is then possible, for example, for the lighting device to already store corresponding specifications for controlling the lighting, which result from the information on the effect of the lighting that has been determined and evaluated by a method and system for controlling a lighting device. This means, for example, that when certain body data are determined, the lighting is controlled in a certain way, as specified by the specifications. This can also depend on the area of ​​application in which the lighting device is arranged.

[0038] It would also be conceivable, however, for the lighting device to be controlled by the corresponding body data, without corresponding specifications being stored in the lighting device, which were determined by a method or system for controlling a lighting device. In this case, it would then be conceivable, for example, for the lighting device to make a change in the lighting and, based on the body data then determined, to determine the extent to which this change in lighting has affected the person's well-being and productivity. This would then enable continuous adjustment.

[0039] The invention will be explained in more detail below using exemplary embodiments and the accompanying drawings. They show: Figure 1: Schematic representation of a system for controlling a lighting device; Figure 2: Schematic representation of a system for controlling a lighting device; Figure 3: Schematic representation of a system for controlling a lighting device; Figure 4: Illustration of various activity trackers for recording body data; Figure 5: Illustration of a smartphone that receives body data.

[0040] As previously explained, light management is becoming increasingly important in a wide variety of lighting technology areas. One area that is likely to become increasingly relevant is the effect of light on people's well-being and productivity. However, the studies available to date have been rather unhelpful, particularly because the number of test subjects was limited due to the relatively high effort involved.

[0041] The dimming and color temperature curves resulting from such studies, which were stored on or in a lighting device in order to control it accordingly, are also rigid and cannot be further adapted, for example, to the local conditions or specific conditions of a user.

[0042] The present invention now provides that a means for acquiring body data acquires body data of a person located in the illumination area or in a predefined area of ​​a lighting device. At the same time, the lighting device acquires corresponding lighting information about the emitted light. The body data and lighting information acquired at a specific, identical point in time are then associated with one another and transmitted to a data collection device. This creates a clear association between the lighting information and the body data acquired at the same point in time, making it possible to evaluate this collected data, in particular with regard to the effect of light on the well-being and productivity of people.

[0043] The lighting information represents a specific lighting situation created by the lighting device, which can, for example, be dimming values ​​or color temperature values.

[0044] In Figure 1 A system for controlling a lighting device is then shown schematically, wherein a means 1 for acquiring body data is provided, which transmits the acquired body data of a person to a data collection device 2. The data collection device 2 additionally receives lighting information from a lighting device 3, wherein the body data and the lighting information were acquired at a specific, identical time. The data collection device 2 then assigns the body data to the corresponding lighting information.

[0045] In order to then determine a correlation between a specific lighting situation, which is defined by the lighting information, and the body data or vital data, the data collection device 2 evaluates the associated body data and lighting information to determine how the lighting situation affects the well-being and productivity of the person in question.

[0046] The person from whom the body data is recorded is located within the lighting area or a predefined area of ​​the lighting device 3, wherein the predefined area of ​​the lighting device 3 can be a sub-area of ​​the lighting area. For example, it can be provided that a lighting device or luminaire is assigned to a specific workstation, and accordingly, the workstation is a specific predefined area.

[0047] It should be noted here that recording a person's body data only makes sense if the person is within the lighting area or the predefined area, since otherwise the light emitted by the lighting device 3 has no influence on the person's well-being or productivity. For this purpose, it can then be provided, for example, that with the help of appropriate means for determining the person's position, the person's position is determined to determine whether the person is within the lighting area or predefined area, e.g., a workplace. Only in the event that the person is then within the lighting area or predefined area of ​​the lighting device are the body data and possibly the lighting information recorded and associated with each other.

[0048] The means for determining the position can be, for example, appropriate GPS means, RFID means, NFC means, or Bluetooth means. However, other means that enable the determination of a person's position are also conceivable. For example, it would be conceivable that a camera arranged in a room or hall could be used to determine the area of ​​the hall or room in which the person is located, which would then make it possible to determine whether the person is in the lighting area or in a predefined area of ​​the lighting device 3.

[0049] The means for determining the person's position are also useful and helpful when a building or building complex is provided with several lighting devices 3, each having a lighting area or a predefined area. In this case, it can be provided that, in the event that the person moves back and forth between the various lighting devices 3, the lighting information of the respective lighting device 3 is linked to the person's body data as soon as the person enters the lighting area or predefined area of ​​the respective lighting device 3. The determination of which lighting area or predefined area the person is currently located in can then be carried out by the means for determining the person's position.

[0050] Alternatively, it could also be provided that the person's body data are assigned only to a predetermined, specific lighting device 3 or its lighting information, e.g., the person's workplace, in the event that the person has a fixed workplace within a building. This means that in this case, assignment would only take place when the person is at work, but not when the person, for example, goes to the cafeteria at lunch.

[0051] Furthermore, it can also be provided that a lighting device 3 and several persons are provided, wherein the lighting information of the lighting device 3 is assigned to the body data of each person.

[0052] In order to obtain the largest possible data collection, it is particularly provided that both lighting information from several lighting devices 3 and body data from several persons are available, wherein the body data of a person is assigned to the lighting information of the lighting device 3 in whose lighting area or predefined area the person is located at the time the lighting information and body data are recorded.

[0053] Furthermore, it is also planned that body data and lighting information will be recorded, for example, every second or minute, over a longer period of time. It is possible to specifically modify the lighting sequence to determine whether corresponding changes in lighting influence the body data, and if so, what kind of influence. By systematically changing the lighting situations, it is possible to gain insights into how the lighting needs to be adjusted to improve the person's well-being or their physical data.

[0054] In principle, it can be provided that, before the start of the recording of body data and lighting information in a lighting device 3, corresponding dimming and color temperature curves are already stored as initial curves, which result, for example, from previously known studies. These dimming and color temperature curves initially help with the control of the lighting device 3, whereby the recording and assignment of body data and lighting information and the corresponding evaluation can provide corresponding new information about the effects of light on a person's well-being or productivity, whereby the initially stored dimming and color temperature curves can then be further improved or recalculated or adjusted. This means, the values ​​stored in the lighting device 3 for controlling the lighting device 3 can be adapted to the information resulting from the evaluation of the corresponding data, wherein this adaptation can take place both before and during an immediate control of the lighting device 3.

[0055] The aforementioned initial curves can then also be stored in the data collection device 2 and then synchronized with the lighting device 3. This also allows a user to customize the curves according to their preferences using a corresponding app. Optimized lighting curves could then be created in the data collection device 2, for example, improved dimming and color temperature curves or corresponding illuminance curves. The optimized lighting curves can then be transmitted to the lighting device 3, which can also be done via a smartphone that is directly connected to the lighting device 3.

[0056] Regardless of whether an adjustment of values ​​stored in the lighting device 3 is performed, and also regardless of whether specific values ​​are stored in the lighting device 3 at all, the control of the lighting device 3 can be provided such that the lighting device 3 is controlled depending on the recorded body data and the information resulting from the evaluation of the collected data. However, it can also be provided that the lighting device 3 is controlled only depending on the recorded body data or only depending on the information resulting from the evaluation of the collected data.

[0057] During control, the recorded body data can therefore be used directly for control purposes, whereby in parallel there is still the possibility that the recorded body data and lighting information are still assigned to one another and transmitted to the data collection device 2 for evaluation.

[0058] Data collection (recording body data and lighting information and relating them to each other), evaluation of the collected data with regard to the well-being or productivity of individuals, and, if necessary, the corresponding adjustment of values ​​and control of the lighting system, can be carried out both within a single building or building complex, as well as across very large, diverse buildings, or even worldwide. This makes it possible to obtain a significantly more comprehensive data set than in previous studies, significantly reducing the risk that individual statistical deviations could impair the significance of the results. Furthermore, the individual daily state of mind of individual individuals no longer has a significant influence on the overall data result.

[0059] This makes it possible, for example, for a manufacturer to obtain relatively good values ​​regarding the effects of light on people's well-being and productivity, independent of individual individuals, based on a relatively extensive data collection. This also makes it possible for a manufacturer to better adapt corresponding lighting devices. It is also possible for a lighting device, for example, to be supplied with the relevant data during its production, so that the lighting device has improved values, e.g., for dimming and color temperature gradients, and accordingly also improved control, regardless of whether the respective users have means for recording physical data. This meansthat the improved data can then also be used in existing lighting devices, regardless of whether body data from corresponding users is transmitted to a data collection facility.

[0060] It is also possible that although appropriate means for recording body data of individuals are available, no data is collected, i.e., there is no association of lighting information with body data, and no such associated data is transmitted to a data collection device for evaluation. In this case, it is merely intended that the lighting device is controlled depending on the recorded body data. Such a system is, for example, Figure 2 shown, in which a means 1 for recording body data and a lighting device 3 are provided.

[0061] When controlling the lighting device 3 in Figure 2Accordingly, the body data are again used to enable optimal control of the lighting device 3. It is also possible to use corresponding means for determining a person's position, whereby it can be determined where a person is located. In this regard, reference should also be made to the previously detailed comments with regard to the means for determining a person's position, which can also be used here in the same way. This means that it can be specified that body data are only recorded and the corresponding lighting device 3 is only controlled when a person is at a certain workstation or in a certain lighting area or predefined area of ​​the lighting device 3. It would also be equally possible, however, for the recorded body data to be used to control exactly the lighting device 3 within a building in whose lighting area orpredefined area the respective person is currently located.

[0062] To which both in Figure 1 as well as in Figure 2 With regard to the means 1 shown for recording body data, it should be noted that this can have a sensor, transmitting and / or receiving unit that is designed to determine or record corresponding body data and subsequently transmit it to another device. The sensor, transmitting and / or receiving unit can, for example, be a so-called activity tracker, which has recently become increasingly common in everyday life. Likewise, the sensor, transmitting and / or receiving unit can also be arranged in a so-called activity tracker. Such activity trackers can, for example, take the form of a wristwatch or a bracelet, whereby these can continuously measure a wide variety of body data.

[0063] In Figure 4Various activity trackers are then shown. These activity trackers are currently mostly used in sports, although other applications are also possible. By measuring the relevant body data, it is possible, for example, to measure or determine a person's stress level or level of alertness, which can then be used to determine how light affects a person. Examples of such activity trackers include the Fitbit, Jawbone Up, and Nike's Fuelband. It could also be a simple manufacturer-specific wristband, manufactured as cheaply as possible, so that it can be fitted to as many people as possible.

[0064] As an alternative to traditional activity trackers, a smartwatch could also be used as a sensor, transmitter, and / or receiver, which also allows for the measurement of relevant body data. The sensor, transmitter, and / or receiver can also be located in a smartwatch.

[0065] Furthermore, other wearable technology devices capable of capturing corresponding body data are also conceivable. In principle, any conceivable sensor, transmitter, and / or receiver unit that enables both the capture of body data and the processing and forwarding of this captured body data is suitable as a means of capturing body data.

[0066] Depending on the sensor, transmitting and / or receiving unit used, it may be useful to provide an additional transmitting and receiving unit to which the sensor, transmitting and / or receiving unit can transmit the body data as a means of recording body data. For example, the activity trackers mentioned above are currently mostly linked to a smartphone, i.e., the recorded body data is transmitted from the activity tracker to the smartphone or the smartphone is connected to the activity tracker. Accordingly, the smartphone is then considered a transmitting and receiving unit. A smartphone that receives corresponding body data is, for example, Figure 5 shown.

[0067] Additionally, it's also conceivable that an app could be installed on a smartphone, for example, allowing a user to adjust certain settings that indicate a person's desired state of well-being, such as whether the person would prefer to relax, etc. It would also be conceivable to change or adjust corresponding dimming and color temperature gradients.

[0068] In the present invention, it can then be provided that the body data acquired by the sensor, transmitting, and receiving unit is transmitted by the sensor, transmitting, and receiving unit to the transmitting and receiving unit, and the transmitting and receiving unit then transmits the received body data to the data collection device. For example, it can be provided that the transmitting and receiving unit also receives the lighting information from the lighting device, and an association of the lighting information and the corresponding body data to one another already takes place in the transmitting and receiving unit, and then the associated body data and lighting information are subsequently transmitted to the data collection device.

[0069] Alternatively, it would also be conceivable for the receiving and transmitting unit to receive the lighting information in addition to the recorded body data, but not yet to assign the body data and lighting information to one another. Instead, it would transmit the body data and lighting information to the data collection device, and only then would the data collection device assign the body data and lighting information to one another. In this case, it would also be possible for the data collection device to directly receive the lighting information from the lighting device and make a corresponding assignment to the body data received by the receiving and transmitting unit.

[0070] Furthermore, it would also be possible for the receiving and transmitting unit to receive the lighting information from the lighting device and then transmit it to the sensor, transmitting and / or receiving unit and for the sensor, transmitting and / or receiving unit to assign the body data and lighting information to one another and then transmit these assigned body data and lighting information directly to the data collection device or via the receiving and transmitting unit to the data collection device.

[0071] Additionally, it is also possible for the sensor, transmitting, and / or receiving unit to be configured in such a way, e.g., in a correspondingly advanced smartwatch, that the sensor, transmitting, and / or receiving unit is directly connected to the data collection device and, accordingly, transmits the body data directly to the data collection device. In this case, it is possible for the data collection device to receive the lighting information from the lighting device and assign it to the body data accordingly.

[0072] It is also conceivable that the sensor, transmitting and / or receiving unit receives the lighting information from the lighting device, makes an assignment to the body data and transmits the mutually assigned body data and lighting information to the data collection device, or that the sensor, transmitting and / or receiving unit receives the lighting information from the lighting device but does not make an assignment to the body data, but transmits the body data and the lighting information to the data collection device, wherein the assignment is then carried out by the data collection device.

[0073] Furthermore, it would also be conceivable for the data collection device to receive the lighting information and then transmit it to the sensor, transmitting and / or receiving unit and for the sensor, transmitting and / or receiving unit to assign it to the body data and then transmit the associated body data and lighting information to the data collection device.

[0074] It should be noted that in the previously described possibilities, it can also be provided that a receiving and transmitting unit is nevertheless arranged between the sensor, transmitting and / or receiving unit, which in this case only serves to carry out the data transmission between the sensor, transmitting and / or receiving unit and the data collection device.

[0075] Overall, it should be noted that the sensor, transmitting and / or receiving unit, or the receiving and transmitting unit, as well as the data collection device, can be designed to receive the lighting information from the lighting device and then either themselves be designed to associate the body data and lighting information with one another or to transmit them to the unit or device that performs the association. Depending on the unit or device in which the association takes place, the body data is transmitted from the sensor, transmitting and / or receiving unit to the receiving and transmitting unit, the data collection device, or via the receiving and transmitting unit to the data collection device. Finally, the associated body data and lighting information are transmitted to the data collection device if the association was not carried out in the data collection device.

[0076] The data collection device can then be located in a central unit of a lighting system in a larger building or building complex, wherein the central unit has, for example, a corresponding server or the like. It is also conceivable that, via corresponding internet connections of the respective devices, the data collection device is located anywhere within the internet, i.e., for example, in a cloud. The corresponding computing and storage capacities can then be made available in the cloud or elsewhere on the internet, e.g., on corresponding server farms. This makes it possible to collect very large amounts of data, both from a very large number of users and from a very large number of lighting devices, in completely different locations around the world, resulting in a study with a very large amount of data that is considerably more meaningful than previous studies.

[0077] A corresponding cloud or server farm could, for example, be a server or server farm belonging to a lighting manufacturer, allowing the manufacturer to collect relevant data in a central location, possibly anonymized, and thus obtain a relatively large study on the effects of lighting on people. This opens up the possibility of future lighting devices being improved accordingly during the manufacturing phase.

[0078] If the data collection device is located in a central office of a building complex or a building, or even somewhere on the Internet, it is possible, for example, for a smartphone to act as a transmitting and receiving unit to communicate with the data collection device via a corresponding connection, e.g., via a Wi-Fi network within a building or via the telephone network and the Internet. It would also be possible, however, for the sensor, transmitting and / or receiving unit to communicate directly with the data collection device without going via a smartphone or a transmitting and receiving unit, in which case the corresponding sensor, transmitting and / or receiving unit would then have, for example, comparable communication means to a smartphone. This is conceivable, for example, in a smartwatch that is further developed accordingly and designed so that it can be operated independently of a smartphone.It would also be possible for a sensor, transmitting and / or receiving unit to communicate with the data collection device via a router, which then serves as a receiving and transmitting unit.

[0079] In Figure 3 A corresponding system for controlling a lighting device is now shown as an example, in which an activity tracker as a sensor, transmitting and / or receiving unit 1 communicates either with a smartphone as a receiving and transmitting unit 4 or with a router 5 and the smartphone 4 or the router 5 then with the data collection device 2. The lighting device 3 is directly connected to the data collection device 2.

[0080] The body data can include, for example, a person's blood pressure, pulse, sweating, body temperature, or the speed and frequency of movement. Using these parameters, it is then possible to determine the extent to which a particular lighting situation influences a person's well-being and productivity.

[0081] For data protection reasons, the present invention preferably provides for the transmitted data to be anonymized. However, on a voluntary basis, it can also be provided that this data be supplemented with personal information, such as age, gender, or the like, to improve data analysis. Furthermore, it is also possible to provide information about a user type, such as production worker, office worker, or patient, or even information about a company where one works. Such data can be entered, for example, using a corresponding app.

[0082] By using appropriate means for recording body data, employees in production or the office, for example, are then used to measure or record corresponding body data, while simultaneously determining or recording corresponding lighting information. This makes it possible to make a statement about the effect of lighting, which is particularly advantageously achieved by changing the light patterns and measuring the person's physiological response to this change.

[0083] With the help of this information, which is transmitted to the data collection device, it is possible to create an improved light profile based on a large amount of corresponding data.

[0084] The voluntarily provided demographic data also makes it possible to combine demographic data, information on the application and body data to make statistical statements about which courses achieve the best physiological effect for certain user groups.

[0085] The advantage of this approach is that a few series of measurements are no longer carried out in the laboratory under unnatural conditions on a small sample of users, which means that reliable conclusions cannot be drawn. Instead, it is now possible to use a very large number of participants, theoretically even from all the data collected worldwide, and from this to obtain a reliable conclusion. As explained above, the body data can be measured every few seconds, for example, resulting in a relatively large amount of data that can be statistically evaluated. Due to the large amount of data, this also has the advantage that statistical interference, such as daily mood, which in previous studies can significantly distort the results due to the small sample size, can be filtered out using the large amount of data.This is particularly important for factors such as well-being and stress levels.

[0086] Both the method and system for controlling a lighting device also offer the possibility for the user to assign the sensor, transmitting and / or receiving unit, e.g., the activity tracker, to a specific lighting device, for example, via a smartphone app. Likewise, it is also possible for a user to determine which lighting devices are relevant to them, i.e., which lighting devices they wish to control. This also applies to the recording and assignment of lighting information and body data, as this allows the user to determine which lighting devices are relevant to them and, accordingly, to which lighting devices a corresponding assignment should be made.

[0087] As mentioned previously, it is also possible that optimized light patterns could also be used in lighting devices where users do not have the appropriate means of recording body data. However, the optimized light patterns would still result in these lighting devices also achieving improved light output.

[0088] In the following, we will briefly discuss some areas of application in which optimizing the control of a lighting device brings advantages.

[0089] In industry, for example, all employees in production environments could be equipped with activity trackers. These measure heart rate, body temperature, movement speed, and movement frequency. If production steps require a very high level of concentration, for example, these parameters can be used to assess a person's stress or fatigue. For this purpose, the parameters are empirically evaluated, and appropriate conclusions are drawn. For example, a reduced movement speed can indicate fatigue, while an increased heart rate and body temperature can indicate a stressful situation.

[0090] When the activity tracker measures these parameters, the lighting system or lighting fixture can react accordingly to the detected situation and, by adjusting the illuminance or color temperature, have an activating or calming effect on the respective people. This improves people's concentration and minimizes the frequency of errors. At the same time, measuring this data can also identify potential health problems and provide better support for employees.

[0091] By recording the data of all participants, we can also empirically determine which light produces the best effect and which lighting situation people prefer. This information can then be used across all projects.

[0092] In office areas, too, all employees in production environments could be equipped with these activity trackers. These measure heart rate, body temperature, speed, frequency, and direction of movement. The principle of activating and calming light can be applied here as well.

[0093] By recording the speed / frequency and direction of movement, a pattern can be created and potentially unnecessary paths can be identified and eliminated. For example, relocating the printer might result in significant time savings.

[0094] In stores, customers should be encouraged to buy. There are current studies on this, such as Limbic Lighting, which suggest optimal dimming and color temperature values ​​for different customer groups. It would be conceivable to measure the body data of customers wearing activity trackers while shopping in order to further optimize the lighting. This would then require motivating customers to participate, perhaps through incentive and discount systems. Furthermore, intelligent positioning can also be used to control the lighting accordingly, motivating customers to buy more items and stay longer in the store.

[0095] In hospitals, for example, optimal lighting can support patient recovery. Here, too, body data can be measured to further optimize lighting patterns. The challenge here is to filter out disease-related body data from the measured data. The large amount of data that can be collected can be helpful here.

[0096] These application examples show that the goals regarding the optimization of lighting control can be different and can also vary depending on the area of ​​use or application.
