    SUMMARY Therefore, there is a need for improved techniques to implement a light characteristic. In particular, there is a need for such techniques that overcome at least some of the limitations and disadvantages mentioned above.
    This object is solved by the features of the independent claims. The features of the dependent claims define embodiments.
    One method includes searching an electronic database with entries for a variety of control gear and for a variety of lights. The browsing is based on a request. The request indicates a light characteristic. The method further comprises determining a combination of a selected operating device from the plurality of operating devices and a selected lamp from the plurality of lamps, and an electrical operating point of the selected operating device. This determination is based on searching the electronic database. The method further includes providing an output. The output indicates the selected control gear, the selected luminaire and the determined operating point.
    The different operating devices can each provide energy for operating the corresponding lamp. For this purpose, the operating devices can comprise, for example, a step-up converter or step-down converter. The operating devices can comprise, for example, a transformer and / or a smoothing filter. The operating devices can for example / 16

    Patent Office wise include an AC / DC converter. Different operating devices from the large number of operating devices can have different specifications with regard to the implementable operating points. For example, some operating devices can provide a greater current or a greater voltage than other operating devices.
    Different types of lights can be used in the various examples described herein. For example, the database could include entries for different types of lights. For example, solid-state-based lights such as light-emitting diodes can comprise lights. Other examples include gas discharge lamps, halogen lamps and incandescent lamps.
    [0009] The electronic database could, for example, be implemented decentrally. For example, the electronic database could be searched via a server connected to the Internet.
    The combination of the selected operating device and the selected lamp, as well as the corresponding electrical operating point of the selected operating device can have a particularly good match with the light characteristic specified in the request. Such techniques can therefore make it possible to identify the combination of selected operating device and selected luminaire with the corresponding operating point that meets the desired light characteristic particularly well. In particular, manual configuration can be omitted or at least supported by the electronic query.
    For example, it would be possible that the method further includes programming the selected operating device for operation at the determined operating point, for example automatically based on the output.
    The programming can include, for example, access to an internal memory of the operating device, wherein corresponding configuration data can be stored in the memory of the operating device. As a result, the operation of the selected operating device can be triggered at the determined operating point. For example, the current-voltage characteristic of the control gear could be set.
    For example, programming the selected operating device could include creating an electronic configuration file. This configuration file could include an identification of the selected operating device, an identification of the selected lamp and a configuration parameter for the operating point. Optionally, the electronic configuration file could also include, for example, an identification of the request or the output in relation to the search of the electronic database. It is then possible for the electronic configuration file to be transmitted to the selected operating device, for example by means of wireless communication, for example Bluetooth, Zigbee, WLAN, etc. Such a technique enables a time separation between the provision of the output and the transmission of the electronic Implement the configuration file to the selected operating device. In this way, for example, the electronic configuration file can be carried out on site during the picking of the selected operating device and the selected luminaire; while the request to the database can be made at another time, for example in a planning phase. This increases flexibility and, in particular, makes picking on site particularly short.
    [0014] In the various examples described herein, one or more different light characteristics can be considered. For example, the light characteristic could comprise at least one element which is selected from the following group: a light intensity; a light color; a light efficiency; a tolerance of light intensity; a tolerance of light color; and spatial light distribution.
    For example, the light intensity can denote the luminous flux related to a certain solid angle, for example in the unit candela. The light color can denote, for example, the spectral distribution or the light temperature of the light. The light efficiency
    2/16
    AT 16 102 U1 2019-01-15 Austrian
    Patent Office can, for example, indicate a relationship between the light intensity and the electrical energy used to operate the corresponding luminaire. The tolerance of the light intensity or the tolerance of the light color can specify an accuracy with which the implementation of a specific light intensity or light color can be guaranteed. It would also be possible for the tolerance to denote a time drift of the corresponding magnitude, for example depending on the operating hours. The spatial light distribution can describe, for example, a geometric radiation characteristic of the luminaire.
    It is possible, for example, that at least some entries in the electronic database specify a dependency of the light characteristic of a respective luminaire of the plurality of luminaires on the combined operating device from the plurality of operating devices. This means that it may be possible that the light characteristics of a particular luminaire vary depending on the operating device with which this luminaire is combined for operation. By mapping this dependency in the database, the desired light characteristic can be implemented particularly precisely.
    Accordingly, it would be possible, for example, for at least some entries in the electronic database to specify a dependency of the light characteristic of a particular luminaire from the plurality of luminaires on the operating point of the combined operating device from the plurality of operating devices. This means that a luminaire can have different light characteristics depending on the operating point at which the combined control gear is operated. By mapping this dependency in the database, the desired light characteristic can be implemented particularly precisely.
    Typically, the light characteristic can thus be set over a certain range by the suitable choice of the operating device and the corresponding operating point. This can result in the fact that the desired light characteristic can be implemented by more than a combination of a selected operating device with a selected luminaire or an associated working point. Therefore, in some examples it would also be possible for several combinations to be determined in each case from a selected operating device and a selected luminaire and an associated electrical operating point and for the output to indicate these multiple combinations. In such a case, the user could select the appropriate combination from the plurality of combinations or specify further criteria in order to narrow the result space.
    Different techniques can be used to generate the entries in the database. In some examples it may in particular be possible e.g. perform one or more calibration measurements as part of a backend test process in production. Such calibration measurements can be carried out for individual lights or for test lights that are representative of several lights, for example in a production series.
    For example, it would be possible for several calibration measurements of the light characteristic to be carried out for a luminaire to be characterized.
    Different calibration measurements of the multiple calibration measurements can relate to different combinations of the luminaires to be characterized with operating devices and / or different operating points of the operating devices. It is then possible to create an entry in the database for the luminaire to be characterized based on the calibration measurements. In other words, this means that it may be possible to test a luminaire to be characterized with several operating devices as part of the corresponding calibration measurements. This means that the lighting characteristics that the corresponding luminaire can provide when combined with the various operating devices can be recorded precisely.
    Depending on the granularity with which these calibration measurements are carried out, it is accordingly possible that the entries in the database are each representative of individual lights or are representative of production series of lights. For example
    3/16
    AT 16 102 U1 2019-01-15 Austrian
    In particular with regard to such lights, which have a large manufacturing tolerance even within production series, it may be desirable for the patent office to carry out the calibration measurements for individual lights. As a result, the light characteristic can be implemented particularly precisely.
    [0023] Various techniques have been described above which make it possible to specify a specific light characteristic based on the request. Alternatively or in addition, it would also be possible for the request to specify one or more properties of the operating device. Examples of such properties can denote, for example, geometric dimensions or compatibility with certain interface technologies. This allows the result space to be narrowed further. For example, it would be possible for the request to continue to indicate an operating mode of the operating device, which is selected from the following group: a light management capability; a drift as a function of time and / or as a function of temperature; a lifetime; a dimmer ability; and a work mode.
    For example, the light management capability can be a compatibility with certain control protocols, such as phase angle modulation of AC AC voltage or Dali bus system or another control bus system. For example, the drift as a function of time and / or as a function of temperature can denote a stability of the selected working point as a function of these parameters. For example, the lifespan can refer to a typical number of operating hours until an error event occurs based on statistical expectations. The dimmer ability can, for example, refer to the ability of the operating device to operate the luminaire at different light intensities. The dimmer working mode can denote, for example, an electronic implementation of dimmer operation. For example, the dimmer working mode could refer to pulse width modulation. For example, the dimmer working mode could denote an operation of a corresponding DC / DC converter, such as continuous operation or intermittent operation.
    The electrical operating point can generally denote different electrical operating characteristics of the operating device. For example, the electrical operating point could denote a power consumption of the operating device. For example, it would also be possible for the operating point to include a load current provided by the operating device to the lamp. The operating point could also include a load current provided by the selected operating device to the lamp as a function of time. The operating point could include a load current provided by the selected operating device to the selected luminaire as a function of the operating time. A drift in certain stability parameters of the control gear could be estimated.
    [0026] A device comprises at least one processor. The at least one processor is set up to carry out the following steps: searching an electronic database with entries for a large number of operating devices and a large number of luminaires based on a request which indicates a light characteristic of a luminaire; based on the search of the electronic database: determining a combination of a selected operating device from the plurality of operating devices and a selected lamp from the plurality of lamps, and an electrical operating point of the selected operating device; and providing an output which indicates the selected operating device, the selected luminaire and the determined operating point.

    In the following, various techniques are described in order to implement a desired light characteristic based on a database query. These techniques are based on the knowledge that a particularly large parameter space differs through many

    Patent office there are possibilities to combine different lights with different operating devices. This parameter is further increased by the possibility of operating operating devices at different operating points. The selection of the suitable combination of control gear and luminaire and associated operating point can therefore be particularly complex and error-prone in reference implementations.
    In the techniques described herein, it is possible to search an electronic database with entries for a variety of control gears and a variety of lights based on a request indicating a light characteristic of a light. It is then possible, based on the search in the electronic database, to determine a combination of a selected operating device from the plurality of operating devices and a selected luminaire from the plurality of luminaires, and an electrical operating point of the selected operating device. An output can be provided which indicates the selected operating device, the selected luminaire and the determined working point.
    [0041] FIG. 1 illustrates aspects related to a system 100 that includes a corresponding database 101. In the example of FIG. 1, the database 101 is accessed by a server 102, for example an Internet server. A user terminal 111, for example a laptop, a cell phone or a portable installation device, is set up to send a request 115 to the server 102. This request 115 indicates a desired light characteristic. The database 101 can then be searched based on this query 115.
    The database 101 has entries for a large number of operating devices 151 and a large number of lights 152. Based on the search of the database, it is possible to determine a combination of a selected operating device 151 from the plurality of operating devices and a selected lamp 152 from the plurality of lamps 152, as well as an electrical operating point of the selected operating device 151. This combination with the associated ones Working point can fulfill the desired light characteristic particularly well. The determined combination together with the working point can be transmitted to the terminal 111 in the form of an output 116.
    [0043] In some examples, for example, a corresponding reproduction could take place on the terminal 111, which indicates the combination with the associated operating point. In some examples, a large number of combinations with associated operating points could also be indexed, so that a user of the terminal 111 could select the suitable combination with an associated operating point.
    In FIG. 1 also shows that it is possible to program the operating device 151 for operation at the determined operating point. Such programming could be done by a manufacturer or an intermediary, for example. A corresponding data connection 155 can then be established between a back-end device 121 and the operating device 151, for example in the area of a factory or a warehouse. Alternatively or additionally, it would also be possible for the operating device 151 to be programmed as part of the picking process. In such an example, a data link 156 could be established between the device 151 and the user's terminal 111 (generally, the same terminal 111 used for request 155 and output 116 could be used for data link 156, or but also another device). The data connection 156 could, for example, be set up in the area of the location where the lamp 152 and the operating device 151 are to be installed.
    The programming of the operating device 151 can include, for example, the creation of a configuration file 157. This configuration file 157 can include an identification of the operating device 151 and the lamp 152, as well as a configuration parameter for the determined operating point. Providing the identification of the operating device 141 and the identification of the lamp 152 can ensure that the correct operating device 151 is set up based on the configuration file 151.

    Patent Office Such techniques as described above with reference to FIG. 1, can be used flexibly for the most varied types of light characteristics. For example, the light characteristic could relate to a certain desired light intensity of the lamp 152. However, it would alternatively or additionally also be possible for it to relate to light characteristics, for example a light color, a light efficiency, a tolerance of the light intensity, a tolerance of the light color and / or a spatial light distribution of the lamp 152. Corresponding information can also be contained in the output 116.
    [0047] FIG. 2 illustrates aspects related to entries in database 101. In the example of FIG. 2, the database 101 comprises several entries 211-213 for different lights 152, as well as several entries 221-224 for different operating devices 151. However, such a structure of the database 101 is purely exemplary and in other examples it would also be possible for different entries, for example describe combinations of lights 152 and control gear 151 directly.
    In the example of FIG. 2, database 101 also includes links 230 between different entries 211-213 for lights 152 and entries 221-224 for operating devices 151 (in FIG. 2, only links 230 for entry 211 are shown for reasons of clarity). These links 230 can denote, for example, a basic compatibility for a combination of the corresponding lamp 152 of the respective entry 211 with the respective operating device 151 of the corresponding entry 221-224. For example, in FIG. 2 scenario illustrated, the lamp 152, which corresponds to the entry 211, is compatible with the operating devices 151, which correspond to the entries 221-223.
    In FIG. 2 also shows that the entries 211-213 for the luminaires comprise, for example, identification of the respective luminaire, for example a serial number, etc. Entries 211-213 also include a type designation and a list of compatible operating devices 151 which defines the links 230. In addition, the specification for the light characteristic is stored in the entries 211213 (the light intensity is shown in the example in FIG. 2).
    In FIG. 2 also shows that the entries 221-224 for the operating devices 151 in turn have an identification of the respective operating device 151. In addition, the entries 221-224 also have a type designation, and a light management capability (FIG. 2 shows whether the Dali bus is supported) and a service life (FIG. 2 shows the average time between error events. mean time between failure).
    The specific information content that can be stored in the different entries 211-213, 221-224 can vary in different implementations.
    Basically, on the basis of such entries 211-213, 221-224, it is possible to specify a dependency of the light characteristic of the respective lamp 152 on the combined operating device 151. In addition, dependencies of the light characteristics of the respective luminaire 152 on the operating point of the combined operating device can be specified.
    [0053] FIG. 3 illustrates aspects relating to a dependence of the luminous intensity of a luminaire on the combined operating device 151 and on the operating point of the respective operating device used. In particular, in FIG. 3 shows the expected light intensity 260 as a function of the load current 261, which the respective operating device 151 provides to the corresponding lamp 152.
    From FIG. 3 it can be seen that different load currents 261 can result in a different light intensity 260. In order to implement the light intensity 115 specified by the query 115 (dashed-dotted line in FIG. 3), only a combination of the corresponding lamp 152 with the operating devices 151, which are described by the entries 221, 223, is suitable. The corresponding operating points 251, 252 are shown in FIG. 3

    Patent office marked.
    [0055] FIG. 4 illustrates aspects relating to a time dependence of the load current 261. In particular, FIG. 4 shows a scenario in which the load current 261 must be adapted as a function of the operating time for the operating device 151 according to the entry 221 for the associated lamp 152 in order to achieve the desired light intensity 260. It would be possible that such a drift as a function of time is stored in the corresponding entry 211-213, 221-224 of the database 101.
    [0056] FIG. 5 is a flowchart of a method according to various examples. First, in step 1001, a database is searched based on a request for a light characteristic. This light characteristic could, for example, relate to a light intensity, a light color, a light efficiency, a tolerance of the light intensity, a tolerance of the light color and / or a spatial light distribution.
    In step 1002, a combination of a selected luminaire and a selected operating device is then determined from a large number of possible combinations. This is based on the light characteristics specified in the request. In some examples, it would also be possible to determine several combinations that can basically implement the requested light characteristic.
    In step 1003, an operating point of the selected operating device is then determined. For example, the operating point can include a load current provided by the selected operating device to the selected luminaire and / or the load current as a function of the operating time.
    In step 1004, an output is then provided that is indicative of the determined combination and the determined operating point. For example, the control gear can be configured appropriately based on the output. Optionally, the luminaire could also be configured appropriately.
    Different techniques are conceivable to determine the entries 211-213, 221-224 of the database 101. Referring to the FIGs discussed above. 3 or 4: For example, corresponding dependencies between the light intensity 260 and the load current 261 and the load current at the determined operating point 251 could be determined under time based on calibration measurements. FIG. 6 is a flowchart of a method that illustrates aspects related to a calibration measurement.
    First, in step 1011, several calibration measurements are carried out for a lamp to be characterized. For example, such calibration measurements could be carried out as part of the backend test in the factory. Different calibration measurements can relate to different combinations of a luminaire to be characterized with operating devices and / or different operating points of the operating devices.
    Then, in step 1012, a corresponding entry in the database is created based on the calibration measurements for the luminaire.
    For example, in some examples it would be possible to use the method according to FIG. 6 to perform for each lamp 152 manufactured. It is then possible that the entries in the database 101 are representative of individual lights 152. In other examples, however, it would also be possible for the method according to FIG. 6 for one or a subset of all lights in a production series - for which a low manufacturing tolerance or parameter variation is assumed. In such an example, it would be possible for the entries in the database to be representative of the series of luminaires. In such an example, it would be possible, for example, for the various entries 211-213 of the database 101 for lights 152 to contain a large number of identifications of lights, namely for all lights of the corresponding production series, for example explicitly or parameterization.
    [0064] FIG. 7 illustrates a flow diagram of an example method. The procedure

    Patent Office includes step 1021, according to which the selected operating device is set. For this purpose, a suitable configuration file can be transferred to the operating device 151 and written, for example, in a memory of the operating device 141.
    [0065] In summary, techniques have been described above which enable an exact implementation of a desired light characteristic. The techniques described here are based on a database that contains entries for various lights and operating devices. This allows tolerances when implementing light characteristics to be mapped in the entries. In particular, a convergence between different types of operating devices and different lights, which are often manufactured by different manufacturers, can be achieved. Inaccuracies and errors in the configuration of the control gear and possibly the lights can be avoided. Automatic configuration of the control gear is possible. Such techniques as described herein can also be used to replace existing lights. In the event of a fault in a lamp, it is possible to replace the faulty lamp with a new lamp. This can be done based on the known or measured light characteristic of the faulty luminaire. The existing operating device can be reprogrammed accordingly, for example based on a configuration file, the corresponding techniques described herein are provided.
    The features of the previously described embodiments and aspects of the invention can of course be combined with one another.
