TEST DEVICE AND METHOD FOR CHECKING A LUMINAIRE

Description

[0001] The invention relates to a method for testing a luminaire with regard to the presence and / or functionality of components of the luminaire, as well as a test device for carrying out this test.

[0002] Methods for testing a luminaire with regard to the presence and / or functionality of components of the luminaire are known from previous practice, wherein the luminaire has various components, such as a control unit, light sources with light source drivers, a bus system, and at least one sensor and / or at least one operating element. Previously, this required the at least one sensor and / or the at least one operating element to be exposed to certain conditions in the installed state, after which it was observed how the luminaire reacts to the control information sent by the sensor. Based on the luminaire's reaction, it is then possible to infer whether individual components are present and / or functioning.

[0003] This previous inspection process is associated with a relatively high level of effort, as each luminaire has to be inspected manually, usually requiring a qualified specialist to operate the luminaire being inspected during the inspection. Furthermore, it has been common practice to use at least one special control device when inspecting the luminaire to determine the functionality of the luminaire's components, or rather the functionality of the luminaire itself. The specialist must also be trained in handling the control device. In previously known methods, the control device is coupled to a luminaire control unit in a complex manner to perform the luminaire testing process.Likewise, in previous inspection procedures, it is common practice for individual control elements of a luminaire and / or sensors to be operated and / or triggered individually and manually by the specialist, so that based on the luminaire's response, it is determined whether the respective component of the luminaire, or the entire luminaire, is functional. Therefore, the current practice for a luminaire inspection process is time-consuming and costly.

[0004] DE 10 2007 055 146 A1 discloses an operating device for at least one light source, which has a physical interface for connecting a light sensor and for inputting light sensor data in a first mode, wherein this interface can be switched to a second mode for outputting data. A reading device can be connected to the physical interface, whereby a supply voltage is then applied to the physical interface by the reading device, which can then be modulated by the operating device and subsequently demodulated and evaluated by the reading device.

[0005] WO 2013 / 126965 A1 describes a method for commissioning an emergency lighting system implemented on a DALI network, whereby the communication of a DALI interface via the DALI network with several distributed loads is addressed.

[0006] DE 10 2016 205 683 A1 shows a vehicle headlight system with a master control device and at least one slave control device, wherein the at least one slave control device is connected to the master control device via a bus system and is responsible for operating the respective associated lighting means.

[0007] From WO 2010 / 043263 A1 an interface device for a DALI system and a method for monitoring it are known.

[0008] DE 102 2007 051 143 A1 shows a monitoring device and a method for monitoring programmable lights.

[0009] The invention is based on the object of specifying a test device or a method for checking the presence and / or functionality of components of the luminaire.

[0010] This object is achieved by a method according to independent claim 1 and by a test device according to independent claim 10. Particular embodiments of the invention are specified in the dependent claims.

[0011] According to the invention, a method for a luminaire testing process is provided for checking a luminaire with regard to the presence and / or functionality of components of the luminaire. The luminaire comprises components such as a control unit, lamps with lamp drivers, and a bus system, wherein the bus system connects the components of the luminaire to one another. The method is characterized in that the bus communication of the luminaire is monitored, and the presence and / or functionality of the components of the luminaire is detected based on bus signals of the monitored bus communication.

[0012] Furthermore, the invention proposes a test device for testing luminaires with regard to the presence and / or functionality of luminaire components during a luminaire testing process. The test device is configured with a bus interface for coupling to the luminaire's bus system, wherein the test device is configured to monitor the luminaire's bus communication and is further configured to detect the presence and / or functionality of the luminaire's components based on bus signals from the monitored bus communication.

[0013] Such a method for testing a luminaire provides a particularly simple and cost-effective way of testing the functionality of the luminaire or the presence and / or functionality of luminaire components. Likewise, the design of the test device simplifies the acquisition of information about the functionality of the luminaire or the presence and / or functionality of luminaire components. The test device according to the invention is particularly suitable for carrying out the proposed method for testing a luminaire. The simplification of the luminaire testing process means that luminaires can be tested particularly time- and cost-efficiently using the method according to the invention and, in particular, the test device according to the invention.

[0014] A particularly advantageous embodiment of the invention is provided in that in the method the luminaire to be tested comprises further components, in particular sensors and / or operating elements, as components of the luminaire, wherein these are preferably also connected to the bus system.

[0015] By designing the luminaire in this way, the functionality and / or presence of corresponding sensors and / or operating elements can be easily detected in a short time during the process, as these also participate in bus communication via the luminaire's bus system. The sensors and / or operating elements are preferably designed in such a way that they can communicate independently with the bus system. For example, a luminaire can be equipped with a presence, motion and / or brightness sensor, whereby independent luminaire operation can be realized so that the luminaire reacts independently to changes in the environment. Luminaires with operating elements such as switches for adjusting the brightness are also conceivable, allowing a user to make targeted changes to the light output of the luminaire.

[0016] According to a further embodiment of the invention for a luminaire testing process, the method is characterized in that, when monitoring the bus communication, the components of the luminaire emitting the bus signals are differentiated and, based on the respective bus communication, the presence and / or functionality of the respective component is recognized.

[0017] This allows, for example, different sensors and / or operating elements or other components to be differentiated in the bus communication, so that a bus communication is clearly assigned to a respective component, whereby, for example, in the luminaire testing process, several lamps with lamp drivers can be differentiated from one another and the presence and / or functionality of each can be individually detected.

[0018] Furthermore, the invention is particularly preferably designed in that the bus system of the luminaire is a DALI bus system.

[0019] Particularly preferably, the invention is designed such that the bus communication of the luminaire is monitored via a luminaire bus interface of the luminaire, wherein the luminaire bus interface is preferably a DALI interface.

[0020] In a further embodiment, the invention for a luminaire testing process is characterized in that a bus converter module is connected to the luminaire bus interface of the luminaire, wherein the bus converter module has a first and a second bus interface, wherein the luminaire bus interface is connected to a second bus interface of the bus converter module such that the bus system of the luminaire is accessible in a bus standard that differs from the bus system of the luminaire.

[0021] Such an embodiment ensures that the bus communication of a luminaire with a bus standard, for example an unusual bus standard, is converted into bus communication with a common bus standard, so that the bus communication of luminaires with any bus standard can be monitored.

[0022] A particularly suitable embodiment of the invention is provided in that the luminaire is supplied with a mains voltage via a mains voltage interface, wherein the luminaire is preferably coupled to the test device via the mains voltage interface, wherein the test device controls the mains voltage supply.

[0023] Such a design makes it possible to influence the luminaire's mains voltage, or to switch the luminaire's mains voltage on and / or off, with the test device itself preferably performing this control. Thus, the luminaire only needs to be connected to the test device, which makes installation of the test device particularly simple, and also enables the test device to influence the luminaire's supply voltage.

[0024] Furthermore, the invention is preferably characterized in that the components of the luminaire are activated when a mains voltage is applied and can send bus signals via the bus system.

[0025] In a further embodiment of the invention, the result of the luminaire testing process is output via an output means.

[0026] This allows the results of the luminaire test to be displayed particularly quickly and easily, without the need for any additional special control devices and / or software. Likewise, no special training of specialists is required to determine the results of the luminaire test, making the procedure for testing a luminaire particularly cost-effective and time-saving.

[0027] According to a further embodiment of the invention, the test device is characterized in that the test device has a power supply interface for supplying the luminaire with a mains voltage.

[0028] With this design, the test device is configured such that a luminaire to be tested can be connected to the power supply interface. The test device can supply the luminaire to be tested with a mains voltage and can independently switch this mains voltage on and / or off. This is also particularly advantageous in combination with the test device's bus interface, whereby the test device is coupled to the luminaire to be tested via both the power supply interface and the bus interface, thus simplifying the luminaire testing process.

[0029] Particularly preferably, the test device is designed to start the luminaire testing process by switching on the mains voltage of the luminaire.

[0030] This advantageously design allows the luminaire testing process to begin with the luminaire's startup process, thus monitoring the luminaire's bus communication as soon as the luminaire is started. This enables a particularly quick and easy test by the test device. The test device connects the luminaire to the mains voltage, preferably via the power supply interface, thereby switching on the luminaire to be tested. The bus communication is monitored by connecting the test device to the luminaire's bus system.

[0031] The test device is further advantageously characterized in that the bus interface of the test device has the same bus standard as the bus system of the luminaire.

[0032] Such a design of the test device enables particularly simple coupling of the test device to the luminaire. It is also conceivable that, if the bus interface of the test device has a different bus standard than the bus system of the luminaire, a bus converter module could be connected between the test device and the luminaire, such that the first bus interface of the bus converter module is coupled to the bus interface of the test device, and the second bus interface of the bus converter module is coupled to the bus system of the luminaire. This allows the test device to monitor the luminaire's bus communication even in such a scenario and, based on the bus communication, detect the presence and / or functionality of the luminaire's components.

[0033] A particularly preferred embodiment of the test device is provided in that the test device has output means for displaying the results of the luminaire test process.

[0034] Such a design ensures that the results of the luminaire testing process are presented in a particularly simple manner, allowing a specialist to read the results particularly quickly and without any further intervention. Therefore, this embodiment is particularly preferred because no special qualifications are required for a specialist to determine the result of the luminaire testing process.

[0035] In a further preferred embodiment, the test device can be reversibly connected to the luminaire, allowing the test device to be coupled and uncoupled from the luminaire to be tested in a particularly simple manner. This significantly simplifies the luminaire testing process.

[0036] The invention is explained in more detail below using exemplary embodiments and with reference to the drawings. They show: Fig. 1: Exemplary embodiment of a luminaire testing process setup with an embodiment of a test device according to the invention and a luminaire to be tested; Fig. 2: Further exemplary embodiment of a luminaire testing process setup with an embodiment of a test device according to the invention, which is coupled to the luminaire to be tested via an intermediate bus converter module; Fig. 3: Exemplary representation of an embodiment of the method according to the invention for a luminaire testing process for testing a luminaire with regard to the presence and / or functionality of components of the luminaire, using an embodiment of a test device according to the invention; Fig. 4: Exemplary representation of a bus communication of a luminaire to be tested, detected and monitored by a test device according to the invention, in a luminaire testing process.

[0037] Figure 1shows the structure of a test device 100 with a lamp 200 in sketch form with the respective individual components of both the test device 100 and the lamp 200. The test device 100 is designed to carry out the lamp testing process of the lamp 200.

[0038] The test device is configured with two interfaces 110, 120. More specifically, the test device 100 has a power supply interface 110 for supplying the luminaire 200 with a mains voltage 111 and a bus interface 120 for coupling to the bus system 240 of the luminaire 200. The test device 100 also has output means 130 for displaying the results of the luminaire test process.

[0039] The luminaire 200 coupled to the test device has a mains voltage interface 210, via which the luminaire 200 is supplied with a mains voltage 111 by the test device 100. Furthermore, the luminaire 200 is configured with a luminaire bus interface 220, wherein the test device 100 is connected to the luminaire bus interface 220 and thus coupled to the bus system 240. For example, the luminaire bus interface 220 is embodied as a Zhaga interface. Likewise, the luminaire 200 has a bus power supply 230, wherein the bus power supply 230 is connected to the bus system 240 of the luminaire 200. The mains voltage interface 210 of the luminaire is connected to the bus power supply 230 as well as to lamps 250 with lamp drivers 251, whereby the lamps 250 with lamp drivers 251 are also connected to the bus system 240.

[0040] In the preferred embodiment shown, the luminaire 200 also has further components 270, in particular at least one sensor 271 and / or at least one operating element 272, wherein these further components 270 are also coupled to the bus system 240. Typically, such luminaires 200 are equipped, for example, with at least one presence, motion, and / or brightness sensor, whereby independent luminaire operation can be realized so that the luminaire 200 reacts independently to changes in the environment. It is also conceivable for luminaires 200 to be equipped with operating elements 272, such as switch elements for adjusting the brightness, so that, for example, a user can make targeted changes to the light output of the luminaire 200.The mentioned embodiments of the further components 270, or the sensors 271 and / or operating elements 272, are not limited to the examples listed, and other sensors 271 and / or operating elements 272 can also be used.

[0041] The luminaire 200 also has a control unit 260, which is also connected to the bus system 240, wherein the control unit 260 controls the operation of the luminaire 200 and its components.

[0042] The components of the luminaire 200, which are connected to one another via the bus system 240 of the luminaire 200, can establish bus communication with one another via this bus system 240, whereby bus signals can be both sent and received by the individual components.

[0043] Preferably, the luminaire 200 is switched on when a mains voltage 111 is applied, whereby the individual components of the luminaire 200 also switch on or activate and send bus signals via the bus system 240.

[0044] In a further embodiment, it is provided that the components of the luminaire 200 automatically send their status via the bus system 240 during the switching-on process of the luminaire 200.

[0045] In a further embodiment, it can be provided that the control unit 260 controls the individual components of the luminaire 200 via a bus signal and thereby receives feedback from the individual components in the luminaire 200.

[0046] The test device 100, which is coupled to the luminaire 200, in particular to the luminaire bus interface 220, via the bus interface 120, is designed to monitor the bus communication of the bus system 240 of the luminaire 200 during the start-up phase of the luminaire 200, and is further designed to detect the presence and / or functionality of the components of the luminaire 200 based on the bus signals of the monitored bus communication. An exemplary representation of a bus communication of a luminaire 200 to be tested, detected and monitored by a test device 100, in a luminaire testing process is shown in Figure 4 shown.

[0047] It is particularly preferred that the test device 100 starts the luminaire testing process by switching on the mains voltage 111 of the luminaire 200 via the power supply interface 110, so that the test device 100 records the bus communication of the bus system 240 throughout the luminaire testing process, wherein in particular the switching on of the luminaire 200 and the activation of the individual components of the luminaire 200 via the bus system are registered by the test device 100.

[0048] In the Figure 1An embodiment is shown in which the test device 100 and the luminaire 200, or rather the bus interface 120 of the test device 100 and the luminaire bus interface 220 of the luminaire 200, have the same bus standard, so that they are directly coupled to one another. By means of this coupling, the bus communication of the luminaire 200 is monitored by the test device 100. Furthermore, the DALI bus standard is preferably used in the bus system 240, so that the bus system 240 of the luminaire 200 is a DALI bus system.

[0049] In the Figure 1In the particularly preferred embodiment of the test device 100 shown, the test device 100 has output means 130 for displaying the results of the luminaire test process. In particular, it can be provided that the test results of individual components are each displayed via the output means. It is also conceivable for the test device to display the results of the luminaire test process collectively via the output means after completion of the luminaire test process.

[0050] In the luminaire testing process of the Figure 1 In the exemplary configuration of a test device 100 and a luminaire 200 to be tested, the test device 100 switches on the mains voltage 111 via the power supply interface 110, whereby the mains voltage 111 is applied to the mains voltage interface 210 of the luminaire 200 and the luminaire 200, or rather the components of the luminaire 200, are switched on.

[0051] During the switch-on process of the luminaire 200, the components of the luminaire 200 send bus signals via the bus system 240. It is conceivable that the respective components of the luminaire 200 signal their operational readiness by means of a bus signal and / or are requested to signal their status via a bus signal by a bus signal from another component, in particular by a bus signal from the control unit 260. In both cases, the bus communication is monitored and detected by the test device 100.

[0052] By coupling the test device 100 to the bus system 240 of the luminaire 200, the test device 100 already monitors the switching-on process of the luminaire 200, wherein the test device 100 is designed to distinguish the bus signals of the components of the luminaire 200 from one another, wherein the test device 100 detects the presence and / or functionality of the respective component based on the respective bus communication.

[0053] On the one hand, it is conceivable that the test device 100 terminates the luminaire testing process after a certain time has elapsed and displays the result via the output means 130. It is also conceivable that the test device 100 automatically detects when all components of the luminaire 200 have sent a bus signal via the bus system 240. It is also conceivable that the test device 100 also detects bus signals that indicate the absence and / or malfunction of a component of the luminaire 200 and displays them accordingly in the result of the luminaire testing process.

[0054] This allows the functionality of a luminaire 200, or rather the functionality and / or presence of components of a luminaire 200, to be determined particularly easily, with a test device 100 being used to carry out the luminaire testing process. The test device 100 is designed to easily and quickly record the result of the test of the luminaire 200 in a luminaire testing process. Particularly preferably, the luminaire testing process runs automatically, so that no inputs or operations by a specialist are required. However, it is also conceivable for the luminaire testing process to be initiated manually, for example, by manually actuating another component 270, such as by triggering a sensor 271 or operating a control element 272.Furthermore, it can be provided that individual method steps of the luminaire testing process are initiated by such manual actuation of another component 270. Furthermore, it is also conceivable for the test device 100 to have additional elements, such as an operating element or a sensor, via which the luminaire testing process is also initiated and / or via which individual method steps of the luminaire testing process are initiated.

[0055] Likewise, the structure of the luminaire testing process is reversible, so that the connection of the test device 100 to the luminaire 200 is designed to be reversible, whereby the test device 100 can be decoupled from the luminaire 200 after completing the luminaire testing process.

[0056] In Figure 2 is a similar setup for a luminaire testing procedure as in Figure 1, wherein the test device 100 and the luminaire 200 differ in the respective bus standard, so that the bus system 240 of the luminaire 200, or the luminaire bus interface 220 of the luminaire 200, has a different bus standard than the bus interface 120 of the test device 100. In the illustrated embodiment, a bus converter module 190 is coupled between the test device 100 and the luminaire 200, or between the bus interface 120 of the test device 100 and the luminaire bus interface 220 of the luminaire 200. Here, the bus interface 120 of the test device 100 is connected to a first bus interface 191 of the bus converter module 190, and the luminaire bus interface 220 of the luminaire 200 is connected to a second bus interface 192 of the bus converter module 190.The bus converter module 190 converts the bus standard of the bus system 240 of the luminaire, which differs from that of the test device 100, to the bus standard of the test device 100, so that the test device 100 can also monitor the bus communication of the bus system 240 of the luminaire 200 via the luminaire bus interface 220 in this embodiment.

[0057] The embodiment with the bus converter module 190 thus enables universal applicability of the test device 100 with luminaires 200, whereby the luminaires 200 can also have different bus standards from the test device. The method for the luminaire testing process in this embodiment does not differ from the luminaire testing process of the Figure 1 shown structure.

[0058] In Figure 3An embodiment of the method for a luminaire testing process for testing a luminaire 200 with regard to the presence and / or functionality of components of the luminaire 200 is shown, wherein the luminaire 200 has components such as a control unit 260, illuminant 250 with illuminant driver 251, and a bus system 240, wherein the bus system 240 connects the components of the luminaire 200 to one another. By way of example, in the Figure 3 The procedure for testing the luminaires described in Figure 1 described in the structure shown.

[0059] In a first method step 1100, a test device 100 switches on the mains voltage 111 of the luminaire 200, wherein the luminaire 200 is preferably connected to the power supply interface 110 of the test device 100 via the mains voltage interface 210. Likewise, the bus system 240 of the luminaire 200 is coupled to the bus interface 120 of the test device 100 via the luminaire bus interface 220. It is also conceivable that the mains voltage 111 is not switched on by the test device 100, wherein the luminaire 200 is supplied with a mains voltage 111 by another means.

[0060] In the illustrated embodiment of the luminaire testing process, the luminaire testing process starts with the switching-on process of the luminaire 200, whereby it is also conceivable that the luminaire testing process is initiated by actuating an operating element 272 and / or by triggering a sensor 271.

[0061] In the subsequent method step 2200, the components of the luminaire 200 are activated and each sends bus signals via the bus system 240 of the luminaire 200. The test device 100 monitors the bus communication and thus also detects and registers the individual bus signals of the respective components (method step 2300). The test device 100 then evaluates the monitored and registered bus signals and detects—preferably automatically—the presence and / or functionality of the components of the luminaire 200 (method step 2400).

[0062] Following the evaluation, the test device 100 outputs the result of the luminaire testing process via the output means 130 (method step 3100), whereby the functionality and / or the presence of components of a luminaire 200 can be recognized in a particularly simple and time-saving manner.

[0063] Figure 4shows an example of an embodiment of the bus signals of the bus communication of the bus system 240 of the luminaire 200 detected and monitored by the test device 100 during a start-up or activation process of the components of the luminaire 200. In the section of the monitored bus communication shown, it is shown by way of example which information the test device 100 receives based on the bus communication, wherein information regarding the sender of the bus signal, the signal type of the bus signal, the signal information of the bus signal and the time stamp of the bus signal in the embodiment of the Figure 4 It is also conceivable that other information is included in the bus signal, wherein the test device 100 is designed to also receive and monitor this other information of the bus signal. In another embodiment, it is conceivable that the bus signals, instead of as in Figure 4The time information shown as an example shows that the system time of the luminaire 200, for example, is included as information in the bus signals of the bus communication. It can be provided that the system time starts with the switch-on process. It is fundamental that the test device 100 is always designed in such a way that it monitors the typical activation process of the components of the luminaire 200 and registers the respective bus signals of the bus communication.

[0064] In the illustrated section of the bus communication, which represents only two seconds of bus communication by way of example, different bus signals from different components of the luminaire 200 are listed. During the luminaire testing process, the test device 100 according to the invention analyzes the different bus signals of the bus communication and, based on this, detects the presence and / or functionality of the individual components of the luminaire 200. In the exemplary section of the bus communication monitored by the test device 100, typical bus signals in the start-up or activation process of the luminaire 200 are shown.

[0065] For example, the test device detects in the Figure 4The illustrated embodiment of the bus communication ensures that a bus power supply 230 is present and functioning properly, as well as that a control unit 260, lamp driver 251, and a brightness sensor 271 are present, each of which functions properly. If, for example, a bus signal with erroneous information or, for example, error messages is included in the monitored bus communication, the test device 100 would also detect that the functionality of components of the luminaire 200 is not present.

[0066] Likewise, for example, the absence of a bus signal from a component of the bus system 240 of the luminaire 200 would lead to a corresponding result regarding the presence and / or functionality of the respective component of the bus system 240 of the luminaire 200. According to a further embodiment, this could be determined by the test device 100, while monitoring the typical activation process of the components of the luminaire 200, reading a bus signal from the control unit 260 in which the control unit 260 requests another component of the bus system 240 of the luminaire 200 to indicate its status, but no status response from the corresponding component is received. It is also conceivable for information about the luminaire 200 being tested to be stored in the test device 100, so that the test device 100 can determine, by comparing this information, whether all expected components of the luminaire 200 are participating in the bus communication.

[0067] The test device 100, or the method for a luminaire testing process, thus allows a particularly quick and easy inspection of a luminaire 200 with regard to the presence and / or functionality of components of the luminaire 200. The test device 100, or the method for testing, is also characterized by the simplicity of performing the testing process, which has a positive effect on the costs of the testing process, since no additional special testing devices and / or operating devices need to be coupled to the luminaire 200 to be tested, and furthermore, no specially trained specialist is required to perform the luminaire testing process. Likewise, the time cost factor is reduced by using the test device 100, or the method for the luminaire testing process, since the testing now takes only a few seconds and is preferably automated.In addition, the result of the luminaire test process is preferably displayed via the output means 130, which allows for quick and uncomplicated evaluation of the results.
