    ARRANGEMENT FOR LIGHTING
    The present invention relates to an arrangement for lighting with a plurality of boards and an operating device for supplying the board with power, the boards each having a lamp unit which each comprises at least one lamp.
    [0002] Light-emitting diodes (LEDs) are used more and more frequently as light sources in various areas of lighting technology, since LEDs have considerable advantages, in particular with regard to service life and energy efficiency, compared to conventional light sources and now also have sufficient light intensity.
    In corresponding arrangements for lighting or lighting arrangements, circuit boards are often used on which the LEDs are arranged accordingly. These so-called LED boards are connected to a corresponding LED converter or a corresponding operating device within the lighting arrangement, the operating device being designed and provided to supply the LED boards and thus the entire lighting arrangement with a correspondingly suitable current.
    In Figure 11, such an arrangement for lighting or lighting arrangement is shown schematically, which shows an operating device 1 and several identical circuit boards or LED boards 2, which are interconnected and connected to the operating device 1.
    Due to the large number of different areas of application in which such lighting arrangements with LEDs are now used, the lighting arrangements can have a significantly different number of LEDs and thus LED boards depending on the use.
    It should be noted that changing the number of LEDs within a lighting arrangement does not necessarily have to change the number of LED boards, since the number of LEDs arranged on each individual LED board could also be changed. However, it would then be necessary for special LED boards to be developed and manufactured for each individual lighting arrangement, which would lead to considerably higher costs.
    Accordingly, it is desirable that the same LED boards can be used for as many different lighting arrangements as possible, in which case more or fewer LED boards can then be provided in the lighting arrangement as required. These LED boards can then be connected to one another in series or in parallel within the lighting arrangement.
    Basically, it is necessary that the LED boards and thus the LEDs are supplied with a correspondingly suitable current by the operating device. The required or desired current then depends on the number of LED boards used and the way they are interconnected. Due to the different number of LED boards and thus LEDs within different lighting arrangements, however, there is the problem that the different lighting arrangements also have different power requirements in order to supply the LED boards and thus LEDs with the correspondingly suitable current.
    This means that depending on the number of LED boards, different operating devices or converters must be provided in the various lighting arrangements. However, since the development and production of different operating devices for different lighting arrangements would lead to significantly higher costs, similar to the LED boards, it would also be desirable for the operating devices that the same operating device can be used for a large number of different lighting arrangements.
    [0010] Furthermore, when connecting LED boards to an operating device,
    note that temperature effects can have an influence on the current. That is to say, temperature fluctuations can mean that the current output by the operating device has to be adapted in a suitable manner, in particular that the power is regulated down in the event of a temperature increase. Such a temperature-dependent regulation is already known for the use of only one LED board, a temperature-dependent resistor being arranged on the LED board. The control gear then detects the resistance value and can adjust the supply current accordingly.
    In lighting arrangements with a different number of several interconnected LED boards, however, the problem arises that it is no longer possible for the operating device to determine a change in temperature based on the resistance value, since depending on the number of the LED boards, the total resistance of the temperature-dependent resistances of the LED boards, regardless of whether they are connected in parallel or in series, changes, which means that it is no longer apparent to the control gear whether the change in resistance is due to a change in temperature or a change in the Number of LED boards.
    For example, a parallel connection of the temperature-dependent resistors of three LED boards has the consequence that the temperature-dependent total resistance value drops to a third (due to the parallel connection of the temperature-dependent resistors of each LED board). However, this would not be easily recognizable for the operating device, since the operating device would interpret a corresponding change in the total resistance value as a change in temperature, at least in the event that the operating device is not aware that the number of circuit boards has changed.
    The object of the present invention is now to create a possibility that the same operating device can be used for different arrangements for lighting, regardless of the number of boards used in the different arrangements for lighting.
    [0014] The object is achieved by an arrangement for lighting according to claim 1 and an arrangement for lighting according to claim 6. Advantageous further developments of the invention are the subject matter of the dependent claims.
    According to the invention, an arrangement for lighting with a plurality of circuit boards and an operating device for supplying the circuit boards with power is provided, the circuit boards each having a lamp unit which each comprises at least one lamp. In addition, the arrangement then also has identification means which enable the operating device to determine the number of circuit boards in the arrangement and to control the current output of the operating device as a function thereof.
    With this configuration, it is now possible for the operating device to determine exactly how many circuit boards are provided in the arrangement for lighting and, based on this number of circuit boards, to control the power output of the operating device to the circuit boards in a suitable manner. This ensures that the circuit boards and the lighting means arranged on the circuit boards are always supplied with the required and desired current.
    [0017] It is preferably provided that the arrangement has a connection box, the circuit boards being connected to the connection box and the operating device being connected to the connection box.
    The connection box can be, for example, a so-called connector that enables a connection between the circuit boards and the operating device.
    [0019] It can also advantageously be provided that the lighting units of the boards are interconnected and connected to the operating device or the connection box, wherein the lighting units of the boards can be connected to one another in series or in parallel. In the case of a parallel connection of the lamp units of each board, it can be provided in particular that the lamp unit of each board is directly connected to the loading
    drive unit or connection box is connected.
    In this case, a direct connection of each board with the operating device or the connection box is provided by a corresponding line. In the case of a parallel connection of the lamp units of the boards with one another, however, it could also be provided that the parallel connections of each lamp unit are routed via the other boards to a first board and then connected from the first board to the operating device or the connection box.
    In the arrangement for lighting can also be provided that the identification means are arranged on the boards, preferably on each board identification means are arranged and the identification means of the boards are interconnected and connected to the operating device or the connection box. The identification means can be connected to one another in parallel or in series.
    As an alternative to this, the identification means can also be arranged in the connection box, wherein in turn identification means can be arranged in the connection box for each circuit board and these can then be connected to one another in parallel or in series.
    In the case of the identification means in the connection box it can then be provided that they can be operated manually. As an alternative to this, however, it can also be provided that the identification means in the connection box are designed in such a way that they are each actuated by connecting one of the light source units of the boards to the connection box, in which case identification means are provided in the connection box for each board and the Lamp units of the boards are connected in parallel with one another.
    The identification means advantageously have a plurality of resistors and the operating device can be designed to determine the total resistance value of the resistors and to determine the number of boards in the arrangement based on the total resistance value.
    As an alternative to this, the identification means can also have only one resistor and the operating device can be designed to determine the resistance value of the resistor and, based on the resistance value, to determine the number of boards in the arrangement.
    The use of only one resistor as an identification means can be provided in particular when the identification means are arranged in the connection box.
    [0027] It can also preferably be provided that the resistance value of the at least one resistor or the resistance values of the plurality of resistors is / are adjustable.
    For the case, for example, that a resistor is assigned to each board as an identification means or a resistor is provided on each board, it then results that the total resistance value changes as a function of the number of boards. This means that, for example, when the resistors are connected in series, the higher the total resistance, the more circuit boards are provided in the arrangement. In contrast, if the resistors were connected in parallel, the total resistance value would be lower the more boards are provided in the arrangement. On the basis of this total resistance value resulting from the number of boards, the operating device is then able to determine the number of boards in the arrangement and to regulate the power supply to the boards accordingly.
    However, it would also be conceivable that the resistance values of individual resistors are changed as a function of the number of boards, which in turn results in a changed total resistance value. A change in the resistance value of individual resistors would be possible, for example, using a potentiometer.
    In the event that a total of only one resistor is provided as an identification means, a potentiometer could also be used. Through this, the resistance value can be changed accordingly depending on the number of boards, whereby the loading
    drive unit is also enabled to determine the number of boards.
    Advantageously, it is then also provided that each lamp unit has a plurality of lamps, in particular LEDs, which are connected to one another in parallel or in series in the lamp unit on the respective circuit board.
    [0032] It can preferably also be provided that the arrangement has temperature measuring means which enable the operating device to determine a temperature change on at least one of the circuit boards and to change the current output of the operating device as a function thereof.
    This configuration makes it possible for the current output of the operating device to be regulated accordingly, for example when the temperature rises.
    In the event that the temperature measuring means are temperature-dependent resistors and thus the temperature-dependent total resistance value changes when the temperature-dependent resistors are interconnected, there is then the possibility that the operating device can correctly detect this, since the operating device has the number of the circuit boards is known by the identification means, which enables the operating device to correctly evaluate the temperature-dependent total resistance value of the temperature-dependent resistors, i.e. the operating device knows that the changed temperature-dependent total resistance value is due to the number of circuit boards in the arrangement and not due to a change in temperature.
    According to the invention, an arrangement for lighting with a plurality of circuit boards and an operating device for supplying the circuit boards with power can furthermore be provided, the circuit boards each having a lamp unit which each comprises at least one lamp. In addition, it is then also provided that the arrangement has temperature measuring means which enable the operating device to determine a temperature change on at least one of the circuit boards and to change the current output of the operating device as a function thereof.
    In this arrangement it is preferably also provided that the arrangement has a connection box, the circuit boards being connected to the connection box and the operating device being connected to the connection box.
    In both arrangements according to the invention it is advantageously provided that the temperature measuring means are arranged on the circuit boards, it being possible for temperature measuring means to be arranged on each circuit board. The temperature measuring means can be temperature-dependent resistors, in particular NTC or PTC resistors.
    In the event that the temperature measuring means are temperature-dependent resistors, the operating device can be designed to determine the total resistance value of the temperature-dependent resistors and to change the current output of the operating device based on a change in the total resistance value, furthermore being provided It is possible that the current output of the control gear is only changed when the total resistance value changes above a threshold value.
    Furthermore, the arrangement can have connecting elements for connecting the boards to one another or for connecting the boards to the operating device or the connection box. The boards can each be connected to one another via a connecting element. In addition, the circuit boards can be connected to the operating device or the connection box via at least one connecting element.
    Advantageously, it can furthermore be provided that the connecting elements have compensation means, in particular compensation resistors, wherein in the event that temperature measuring means are arranged on each board, the temperature measuring means of a board with the compensation means of a connecting element form a parallel circuit or a series circuit can, wherein the individual parallel circuits are connected in series with one another and the individual series circuits are connected in parallel with one another. Alternatively, the temperature measuring devices of the boards and the compensation
    sationsmittel of the connecting elements also form a mixture of a series and parallel connection.
    It would also be possible that compensation means, in particular compensation resistors, are arranged in the connection box, in which case the temperature measuring means of the boards can be connected in parallel or in series and the parallel connection can be connected in series and the series connection in parallel with the compensation means in the connection box can.
    These special configurations then result, in the event that the temperature measuring means are designed as temperature-dependent resistors, the advantage that the temperature-dependent total resistance value corresponds to the resistance value of a single temperature-dependent resistor on a board, whereby the operating device is independent of the number of Boards and thus the interconnected temperature-dependent resistors always record the same temperature-dependent total resistance value and this is therefore not mistakenly recognized as a temperature change by the operating device.
    The invention will be explained in more detail below with reference to exemplary embodiments and the accompanying drawings. Show it:

    FIG. 11 shows a schematic representation of an already known arrangement for lighting.
    FIG. 11 shows schematically, as already explained, an already known lighting arrangement or arrangement for lighting, in which several LED boards or boards 2 are provided. The boards 2 are configured identically, LEDs being arranged on the boards. This means that each board 2 includes the same number of LEDs. The use of the same circuit boards 2, which are always the same as possible, in different arrangements for lighting is advantageous, inter alia, because this can reduce the costs for the development and manufacture of many different circuit boards. However, since different arrangements for lighting, which are to shine with different brightness, for example, are also required for different tasks, provision is then made for a different number of identical circuit boards 2 to be provided in an arrangement for lighting, depending on the application.
    Due to the different number of circuit boards 2, the problem then arises that, depending on the number of circuit boards 2, the power requirement of all circuit boards 2 provided in an arrangement for lighting also changes. In previous arrangements for lighting, as shown in FIG. 11, an LED converter or operating device 1 is provided which accordingly supplies the circuit boards 2 with current. This means that the current required by the circuit boards 2 is made available by the operating device 1, which then results in the problem that, depending on the number of circuit boards 2 provided, the operating device 1 has to provide a different current. Accordingly, it has hitherto been necessary, depending on the number of circuit boards 2, to use a different operating device 1, as a result of which considerable costs were required for the development and production of a large number of different operating devices 1.
    According to the invention it is now provided that an arrangement for lighting with several circuit boards and an operating device for supplying the circuit boards with power has identification means which enable the operating device to determine the number of circuit boards and to control the power output of the operating device as a function thereof. The circuit boards each have a light source unit which each includes at least one light source.
    By the identification means, it is now possible that one and the same operating device for a variety of different arrangements for lighting, in which a different number of boards is provided, can be used and it is still ensured that the boards with the appropriate and appropriate required electricity.
    Furthermore, in arrangements for lighting that have one or more circuit boards 2, as shown in FIG. 11, which are connected to an operating device 1, provision is often made for corresponding temperature measuring means, for example temperature-dependent resistors, to be provided on the circuit boards 2 which detect the temperature, which enables the operating device 1 to regulate the power supply to the circuit boards 2 accordingly in the event of a temperature change, for example to reduce the power supply in the event of a temperature rise.
    When using temperature-dependent resistors, however, there is the problem that when the temperature-dependent resistors of the various boards 2 are interconnected, the temperature-dependent total resistance value depends on the number of boards 2.
    This means that when the number of boards 2 changes, the temperature-dependent total resistance value also changes, whereby the operating device 1 would erroneously assume a temperature change, in the event that the operating device 1 is not known that the number of PCB 2 has changed.
    It should be noted here that it would theoretically also be possible that, depending on the number of boards 2, different temperature-dependent resistances would be used on the boards 2 in order to achieve a temperature-dependent total resistance value that is as constant as possible. However, this would involve considerable effort, since, depending on the number of circuit boards 2, different circuit boards 2 would always have to be used. As already explained above, however, it is desirable that the same boards 2 can be used whenever possible, regardless of the number of boards 2.
    As already explained above, the inventive arrangement for lighting makes it possible to determine the number of circuit boards by means of the identification means. On the one hand, this makes it possible for the operating device to control the power output as a function of the number of boards. On the other hand, this also creates the possibility that the operating device uses the number of boards to determine how high the temperature-dependent total resistance value of the interconnected temperature-dependent resistors of the individual boards must be.
    This means that the operating device does not have to know in advance how high the temperature-dependent total resistance value resulting from the number of boards is,
    rather, it is easily possible for the operating device to subsequently determine the temperature-dependent total resistance value on the basis of the number of boards resulting from the identification means. It is only necessary that the control gear knows how high the resistance value of a temperature-dependent resistor on a board is (the temperature-dependent resistors of the boards must all have the same resistance value) and how the individual temperature-dependent resistors of the boards are connected to one another (parallel or serial). With the help of the number of circuit boards, which results from the identification means, the operating device can then calculate the temperature-dependent total resistance value, which is lower when the temperature-dependent resistors are connected in parallel and the greater the number of circuit boards and when the temperature-dependent resistors are connected in series, the higher it is the greater the number of boards.
    As an alternative to this, however, it could also be provided that the temperature-dependent resistors of the boards are interconnected with one another in such a way that by additional compensation means or correction means, in particular in the form of resistors, which are provided for example on additional elements or in a connection box always results in the same temperature-dependent total resistance value, which means that it is irrelevant for the operating device with regard to the detection of a temperature change how many circuit boards are connected to the operating device.
    In Figures 1 to 8 then eight different embodiments of the inventive arrangement for lighting are shown schematically in detail, it should be noted that all eight embodiments each show a specific design of the identification means in combination with a specific design of the temperature measuring means, wherein also different interconnections of the boards with one another are shown in the eight exemplary embodiments. It should be noted here, however, that the eight exemplary embodiments in FIGS. 1 to 8 are merely examples. Other combinations of the design of the identification means with the temperature measuring means and interconnection of the boards with one another would also be conceivable. It is also not necessary for the identification means to be used together with the temperature measuring means, since it is also possible for them to be used independently of one another.
    In all eight exemplary embodiments in FIGS. 1 to 8, an operating device 1, a connection box 3 and three circuit boards 2 each are shown. The circuit boards 2 each have a lamp unit, each lamp unit comprising three LEDs 4. In the eight exemplary embodiments in FIGS. 1 to 8, the three LEDs 4 of a lighting unit are connected to one another in series and accordingly form a series circuit within the respective lighting unit. However, it would also be conceivable that a different number of LEDs 4 is provided. Likewise, the LEDs 4 of a lighting unit could also be connected to one another in parallel within the lighting unit and thus form a parallel connection.
    The lamp unit of each board 2 is then connected as a whole with the lamp units of the other boards 2, the eight exemplary embodiments of FIGS. 1 to 8 showing both a parallel and a serial connection of the lamp units to one another.
    In the eight exemplary embodiments of FIGS. 1 to 8, the connection or interconnection of the circuit boards 2 with the operating device 1 then takes place via the connection box 3, the essential connections of the operating device 1 being passed through the connection box 3 and the circuit boards 2 then connected the connection box 3 can be connected. Such a connection box 3 can for example be designed as a so-called plug connector.
    In Figures 1 to 8, the connection box 3 is shown as a single separate component. However, it would also be conceivable that the connection box 3 or its functions could be integrated into the operating device 1 itself, or that the operating device 1 itself fulfills the corresponding functions and tasks of the connection box 3, for example in such a way that in some of the exemplary embodiments in the connection box 3 integrated identification means 5 or compensation means 12 are provided directly in the operating device 1.
    71727
    The operating device 1 then has, among other things, four connections 6, 7, 8 and 9, the first connection 6 being a power supply connection to which the interconnected lighting units of the circuit boards 2 are connected for power supply. Corresponding temperature measuring means 10 are connected to the second connection 7 of the operating device 1. In contrast, the third connection 8 is connected to the identification means 5. The connection 9 is a ground connection to which both the lamp units and the temperature measuring means 10 and identification means 5 are connected.
    The temperature measuring means 10, which are provided in the arrangement for lighting in the eight exemplary embodiments of FIGS. 1 to 8, enable the operating device 1 to determine a temperature change on at least one of the circuit boards 2 and to change the current output of the operating device 1 as a function of this. In FIGS. 1 to 8, the temperature measuring means are designed as temperature-dependent resistors 10, in particular NTC resistors, the resistance value of the respective NTC resistor 10 changing when the temperature changes.
    In the eight embodiments of Figures 1 to 8 it is provided that the NTC resistors 10 with additional compensation means, in particular compensation resistors or correction resistors 12, are each connected in such a way that the temperature-dependent total resistance of the NTC resistors 10 does not depend on the Number of boards 2 and thus the number of NTC resistors 10 is dependent, but regardless of the number of boards 2 or NTC resistors 10 always has the same value, in particular the same value as a single NTC resistor 10.
    It should be noted that an NTC resistor 10 is provided on each board 2 and the compensation resistors 12 on additional connecting elements 11, which are provided for connecting the boards 2 to one another or for connecting the boards 2 to the connection box 3, or are arranged in the connection box 3. On the one hand, it is then provided that the NTC resistor 10 of a circuit board with the compensation resistor 12 of a connecting element 11 forms either a parallel circuit or a series circuit, the individual parallel circuits then being interconnected in series and the individual series circuits then being interconnected or connected in parallel with one another The NTC resistors 10 of the boards 2 and the compensation resistors 12 of the connecting elements 11 form a mixture of a series and parallel connection. On the other hand, it is provided that the NTC resistors 10 of the boards 2 are connected to one another in parallel or in series, the parallel connection being connected in series and the series connection being connected in parallel with one of the compensation resistors 12 in the connection box 3.
    With regard to the identification means, it should be noted that in FIGS. 1 to 8, resistors 5 are provided as identification means, with each board 2 being assigned a resistor 5 as identification means in the eight exemplary embodiments. The resistors 5 are either arranged directly on the circuit boards 2 in FIGS. 1 to 8 or are located in the connection box 3. Both on the circuit board 2 and in the connection box 3, the resistors 5 are connected either in parallel or in series. That is, depending on the number of circuit boards 2, there is a different total resistance value, whereby the operating device 1 is able to determine the number of circuit boards 2 and control or regulate the current output of the operating device 1 accordingly, so that the circuit boards 2 or The lighting units of the circuit boards 2 and thus the LEDs 4 can be supplied with the appropriate or required current.
    In FIGS. 1 to 8, a temperature-dependent resistor 10 or a resistor 5 per circuit board 2 is provided for both the temperature measuring means and the identification means. However, this is not absolutely necessary.
    It would also be conceivable, for example, for one or more resistors to be arranged in the connection box 3, the number of resistors not having to correspond to the number of circuit boards 2. In particular, it can then be provided that these resistances are adjustable
    are cash. For example, a single potentiometer could be provided in connection box 3 with which different resistance values can be set, which then signal the number of circuit boards 2 to operating device 1. This would make no difference for the operating device 1, since the operating device 1 only records the total resistance value and, based on this, determines the number of circuit boards.
    With regard to the arrangement of identification means in the connection box 3, it should also be noted that a single fixed resistor can also be provided in the connection box 3 and, depending on the number of boards 2 in the arrangement for lighting, another connection box 3 with a Another resistor is used and the corresponding information is transmitted to the operating device 1 as a result. However, this does not have to be done specifically via a resistor, but would also be possible in another way, such that the connection box 3 contains information about the number of circuit boards 2 and this is then transmitted to the operating device, for example digitally, possibly via a bus or analog. It would also be conceivable that the connection box 3 contains a memory chip on which the number of circuit boards 2 is stored and the operating device 1 then reads out this information accordingly.
    In general, if the connection box 3 already contains fixed information about the number of circuit boards 2, it can be provided that the connection box 3, for example when the circuit boards 2 are connected in parallel, have the same number of connections for the lamp units connected in parallel of circuit boards 2 has the number of circuit boards 2 that is stored in connection box 3 as information.
    In the following, the individual exemplary embodiments shown in FIGS. 1 to 8 will now be discussed in greater detail.
    In FIG. 1, a first exemplary embodiment is shown in which a resistor 5 is provided as identification means on each board 2, the resistors 5 of the boards 2 being interconnected in series. Accordingly, the greater the number of circuit boards 2, the higher the total resistance value of the identification means. The resistors 5 connected to one another in series are then connected to the third connection 8 of the operating device 1 via the connection box 3. It should be noted here that the operating device 1 must know that the resistors 5 are connected to one another in series and that an increase in the number of circuit boards 2 leads to an increase in the total resistance value.
    Furthermore, it can be seen from FIG. 1 that in the first exemplary embodiment the lighting units of the circuit boards 2 are serially interconnected and the serially interconnecting illuminant units are then connected via the connection box 3 to the first output 6 of the operating device 1 for power supply.
    Furthermore, in the first exemplary embodiment in FIG. 1, an NTC resistor 10 is also provided on each board, the NTC resistors 10 of the individual boards 2 then actually being directly and directly connected in series with one another. In this case, however, there is the problem, as already explained above, that the higher the number of boards 2, the higher the temperature-dependent total resistance value would be, whereby the operating device 1 would erroneously assume a temperature change in the event that the operating device 1 does not Number of boards 2 would take into account when evaluating the temperature change or the temperature-dependent total resistance value.
    To ensure that the temperature-dependent total resistance value of all interconnected NTC resistors 10 is independent of the number of boards 2 or NTC resistors 10, the compensation resistors 12, which are arranged on the connecting elements 11, are also provided .
    In FIG. 1, a connecting element 11 is assigned to each board 2, the NTC resistor 10 of a board 2 forming a parallel circuit with the assigned compensation resistor 12. These parallel connections of the NTC resistors 10 with the compensation
    Resistors 12 are then connected to one another in series. This means that the total resistance of the NTC resistors 10, which are actually connected in series, can be influenced by the compensation resistors 12 arranged in parallel in each case in such a way that a constant total resistance can be achieved regardless of the number of boards 2 and thus the NTC resistors 10, for example a total resistance value which corresponds to the resistance value of an individual NTC resistor 10.
    It should be noted that the required resistance value of the compensation resistors 12 depends on the number of boards 2 used, since depending on the number of boards 2, a different compensation resistance value is required as compensation. It should be noted here that, depending on the number of boards 2, different connecting elements 11 must be provided, but these differ only with regard to the compensation resistor 12 and are also significantly less expensive than corresponding different boards 2, since on these connecting elements 11, for example no LEDs 4 are arranged.
    With regard to the connecting elements 11 it should be noted that in Figure 1 it is also provided that the connecting elements 11 have both a ground connection and the connection of the resistors 5 of the identification means and the connection of the lamp units from one board 2 to the next board 2 loop through or connect.
    The interconnected NTC resistors 10 and compensation resistors 12 are then connected via the connection box 3 to the second connection 7 of the operating device 1, the second connection 7 of the operating device 1 already being split into two lines in the connection box 3, so that the parallel connection of the compensation resistor 12 with the NTC resistor 10 on the first connected board 2 is easily possible.
    FIG. 2 then shows a second exemplary embodiment of an arrangement according to the invention for lighting, the interconnection of the NTC resistors 10 with the compensation resistors 12 and the control or interconnection of the lighting units with one another being comparable to the first exemplary embodiment.
    The essential difference between the second exemplary embodiment and the first exemplary embodiment is that the identification means, which are designed as resistors 5, are not interconnected in series but in parallel. It then follows from this that the total resistance value of the resistors 5 becomes lower the greater the number of printed circuit boards 2. This means that the operating device 1 in turn detects the total resistance value to determine the number of printed circuit boards, but the operating device 1 must be aware that the identification means designed as resistors 5 are connected to one another in parallel and not in series, and accordingly an increase in the number of printed circuit boards 2 leads to a decrease in the total resistance value.
    In addition, in the exemplary embodiment in FIG. 2 it is also provided that the second connection 7 of the operating device 1 is not divided up in the connection box 3. Rather, an additional connecting element 11 is provided that serves to split this connection 7 and thus enables the NTC resistor 10 of the first circuit board 2 to be connected in parallel with a compensation resistor 12. It should be noted, however, that the compensation resistor arranged on this connecting element 11 is not used, that is, this connecting element 11 only serves to split up the connection accordingly. However, in order to have to use as few different components as possible, a connecting element 11 that is the same as the other connecting elements 11 is used here despite everything.
    In the third exemplary embodiment in FIG. 3, such an additional connecting element 11 is not required, since the second connection 7 of the operating device 1 is again split up in the connection box 3. The third exemplary embodiment then differs from the second exemplary embodiment essentially in that the luminous
    Medium units are not interconnected in series but rather in parallel. In Figure 3 it is provided for this purpose that a separate connection to the connection box 3 runs from each lamp unit, these connections then being looped through or further connected via the other boards 2 and the connecting elements 11, so that only a single first board 2 is immediate and direct is connected to the connection box 3, with a separate connection between the connection box 3 and this one connected to the connection box 3 first board 2 being provided for each lamp unit of each board 2. The division of the first connection 6 of the operating device 1 already takes place in the connection box 3.
    However, it would also be conceivable that only one connection is provided in the connection box 3 for the lamp units and accordingly only one connection or line is provided on the boards 2 or connecting elements 11, but then each lamp unit from this individual line Electricity is tapped and thus there is still a parallel connection of the lamp units (interconnection similar to a bus system).
    In the fourth exemplary embodiment in FIG. 4 it is then provided that the identification means designed as resistors 5 are no longer arranged on each individual circuit board 2, but rather together in the connection box 3. Otherwise, the fourth exemplary embodiment corresponds to the third exemplary embodiment in FIG. 3 .
    Specifically, in the fourth exemplary embodiment in FIG. 4, provision is made for a resistor 5 to be arranged in the connection box 3 for each circuit board 2, with each resistor 5 being assigned corresponding means by which the respective resistor 5 is activated or deactivated can be. This means that the respective resistor 5 can be switched on or off and thereby changes the total resistance value of the identification means. In the fourth exemplary embodiment, it is provided in particular that the resistors 5 are connected in parallel, that is to say that the total resistance value drops by adding a further resistor 5.
    In Figure 4 it is then also provided that by connecting a connection, for example a cable, of the lamp units to the connection box 3, the resistor 5 is activated and thus switched on. It should be noted that, as in the third exemplary embodiment, also in the fourth exemplary embodiment, the lighting units of the circuit boards 2 are interconnected in parallel, with each lighting unit being connected separately to the connection box 3, but the connections being looped through or via the connection elements 11 and the circuit boards 2 are further connected, so that a first board 2 is connected to the connection box 3, with a separate connection between this first board 2 and the connection box 3 for each lamp unit.
    To activate or deactivate the resistors 5, a switch can then be provided as a corresponding means, which switch is actuated by plugging in a cable. Other mechanical solutions or the use of optocouplers would also be possible. Alternatively, the insertion of a cable can also be detected using other methods, such as capacitive coupling, light barrier, photocell, etc.
    In Figure 5 then a fifth embodiment of the inventive arrangement for lighting is shown, the arrangement and interconnection of the lighting units of the circuit boards 2 and the arrangement and interconnection of the NTC resistors 10 with the compensation resistors 12 is comparable to the second embodiment. One difference now, however, is that, similar to the fourth exemplary embodiment, the identification means designed as resistors 5 are arranged in the connection box 3 and are again connected to one another in parallel. It should be noted, however, that here the resistors 5 are not deactivated or activated and thus switched on or off by plugging in and unplugging a cable, but that this is done using manual switches. For this purpose, reference should also be made to FIG. 9, in which a corresponding connection box 3 is shown, with DIP switches that enable the resistors 5 to be switched on and off accordingly.
    chen.
    In the sixth exemplary embodiment shown in FIG. 6, the lamp units are then again connected to one another in parallel, similar to what is shown, for example, in the third and fourth exemplary embodiments. In contrast to the third and fourth exemplary embodiments, however, the lighting units of each circuit board 2 are directly connected to the connection box 3 via a connection, in particular a cable. This means that each circuit board 2 is connected to the connection box 3 by a cable or a connection for the respective lamp unit.
    The connections of the lamp units are accordingly not looped through or further connected via the respective other boards 2 and connecting elements 11. The identification means designed as resistors 5 are also arranged in the connection box 3 in the sixth exemplary embodiment, similar to the fifth exemplary embodiment in FIG. 5, with the resistors 5 being able to be switched on and off manually as in the fifth exemplary embodiment, although the lamp units each have one Have a cable connection to the junction box 3. In contrast to the fifth exemplary embodiment, however, the resistors 5 are connected to one another in series, which means that by connecting a resistor 5, it is connected in series to the other already connected resistors 5 and thus has to be added.
    In addition, a different interconnection of the NTC resistors 10 is now also shown in the sixth embodiment. It is specifically provided that the NTC resistors 10 are connected in parallel to one another. By connecting the NTC resistors 10 in parallel, however, the total resistance value would then be correspondingly reduced for each additional board 2 added, each of which has an NTC resistor 10. In order to compensate for this, connection elements 11 with compensation resistors 12 are again provided, but these are then each connected in series to an associated NTC resistor 10. This means that a compensation resistor 12 of a connecting element 11 together with an NTC resistor 10 of an associated circuit board 2 forms a series circuit. However, these series connections are then connected to one another in parallel. Overall, a temperature-dependent total resistance value then results which is independent of the number of boards 2.
    In order to achieve a temperature-dependent total resistance value which corresponds to the value of an individual NTC resistor 10, it is again necessary to use different compensation resistors 12 depending on the number of boards 2.
    In Figure 7, a seventh embodiment is then shown. It is provided that the lighting units of the circuit boards 2, as in the sixth exemplary embodiment, are connected directly and directly to the connection box 3. The identification means designed as resistors 5 are arranged in the connection box 3 as in the fourth embodiment, these being activated or deactivated and thus by plugging in or unplugging the corresponding connection or the corresponding cable, as in the fourth embodiment in FIG can be switched on or off. In addition, in the seventh exemplary embodiment, a further different connection of the NTC resistors 10 and the compensation resistors 12 is shown.
    Specifically, it is provided that the NTC resistors 10, which are actually interconnected in parallel, form a mixture of a series and parallel circuit with the connecting elements 11 and the compensation resistors 12. The resulting circuit is shown schematically in the lower right third of FIG.
    It is provided that the connection for the temperature-dependent resistors between the first board 2 and the connection box 3 is connected to another connection of the first board 2, depending on the number of boards 2, for example. With only one board 2, the connection would be used, which is directly connected to the NTC resistor 10 of the first board 2 in connection. With three boards 2, as shown in Figure 7, the second connection is connected from above.
    applies, with four boards 2 the top connection would be used and with two boards 2 the third connection from the top would be used.
    The connecting elements 11 then also have a bridge, a switch or button or the like, which is closed only for the connecting element 11 which follows the first board 2 and is open for all other connecting elements 11. This and the arrangement and interconnection of the compensation resistors 12 on the connecting elements 11 then results in the circuit shown in the lower right third of FIG. 7, the connecting elements 11 also establishing further connections between the boards 2 for this purpose, as shown in FIG .
    The compensation resistors 12 now have a resistance value which corresponds to half the resistance value of the NTC resistors 10, which results in a temperature-dependent total resistance value in the circuit shown in the lower right third of Figure 7, which is the resistance value of an individual NTC Resistance 10 corresponds. It should be noted that this also applies to a larger number of circuit boards 2 and, accordingly, additional connecting elements 11, because due to the special interconnection of NTC resistors 10 with connecting elements 11 and compensation resistors 12, the temperature-dependent total resistance value is always the resistance value of an individual NTC resistor 10 corresponds. Thus, regardless of the number of boards 2, the same connecting elements 11 with the same compensation resistors 12 can always be used.
    In the eighth exemplary embodiment in FIG. 8, a further different interconnection of the NTC resistors 10 and the compensation resistors 12 or a compensation resistor 12 is then provided. Specifically, it is provided that all NTC resistors 10 of the boards 2 are connected directly to one another in parallel, the connecting elements 11 not having any corresponding compensation resistors, but merely establishing a connection between the boards 2.
    In order to bring the temperature-dependent total resistance value reduced by the parallel connection of the NTC resistors 10 back to the same value as that of an individual NTC resistor 10, it is then provided in FIG. 8 that corresponding compensation resistors 12 are arranged in the junction box 3 are. The parallel connection of all NTC resistors 10 is then connected in series to one of the compensation resistors 12 in connection box 3 so that the temperature-dependent total resistance value again corresponds to the resistance value of an individual NTC resistor 10.
    For this purpose, several different compensation resistors 12 are provided in the connection box 3, each corresponding to a different number of boards 2, i.e., depending on the number of boards 2, the connection is made to a different compensation resistor 12 in the connection box 3.
    Likewise, it would also be possible that the same connection is always used on the connection box and the selection of the corresponding compensation resistor takes place internally within the connection box, for example via switches or buttons, or an electrical detection of the resistance value of the parallel connection of all NTC resistors and an automatic integration of the corresponding compensation resistor is provided. Furthermore, it would also be possible, for example, to use a potentiometer instead of the multiple compensation resistors, which then has the correspondingly required resistance values.
    The resistance value of the compensation resistor in the eighth embodiment results as follows:
    (n-1)
    RNTC, compensation =: Ryıre applies to Rare, = Rute = Rure, z = Rure, 3 = ..., where n is the number
    the NTC resistors and, without a compensation resistor, with a pure parallel connection of the individual NTC resistors, the following temperature-dependent total resistances
    stand value would result in:
    RuTc n
    RyTc, paralttei = applies to Ryrc = Rare = Rute = Rurte3 7 +
    From this it follows that when using the compensation resistor, the temperature-dependent total resistance value corresponds to the resistance value of an individual NTC resistor:
    > RyTc, total = RyTc, paralt + RuTc, compensation
    R n-1 nrc) n
    => RuTtc, total = rod
    RyTc, total = ‘tail
    Thus, regardless of the number of boards 2, the same connecting elements 11 can always be used here. Since no compensation resistors are arranged on the connecting elements 11 in FIG. 8, it would also be possible to dispense with the connecting elements entirely and to connect the circuit boards directly to one another, for example with corresponding lines or wires.
    The identification means formed in Figure 8 as resistors 5 are compared to the seventh embodiment shown in Figure 7 again arranged on the board 2 and serially interconnected, comparable to the first embodiment. Likewise, as in the first exemplary embodiment, the lamp units are connected to one another in series and then connected to the connection box 3.
    In the eighth exemplary embodiment in FIG. 8, the NTC resistors 10 of the circuit boards 2 are connected in parallel to one another and the parallel connection of all NTC resistors 10 is then connected in series to one of the compensation resistors 12 arranged in the connection box 3. However, there would also be the possibility that the NTC resistors are connected to one another in series and then the series connection of all NTC resistors is connected in parallel to one of the compensation resistors arranged in the connection box. For this purpose, the connection box would have a connection to which the series circuit of all NTC resistors is connected, the connection of the connection box then being interconnected internally so that the series circuit is connected in parallel to a compensation resistor. The correct compensation resistor can be selected in a manner comparable to that in the eighth exemplary embodiment in FIG. 8, for example using a switch or button or electrical detection of the resistance value, with the correct compensation resistor resulting as follows:
    - RurTtc. un _ RNTC, compensation = fax applies to Ryre = Ryre, .1 = Rure, 2 = Rurte3 = ...
    where n indicates the number of NTC resistors and, without a compensation resistor, if the individual NTC resistors were connected in series, the following temperature-dependent total resistance would result:
    RüuTc, serieu = rods applies to Ryre = rod = Rure2 = Rurte3 = ...
    From this it follows that when using the compensation resistor, the temperature-dependent total resistance value corresponds to the resistance value of an individual NTC resistor:
    RNTCseriell * RNTC, compensation
    > RyTc, total =; g RNTC, serial + RNTCc, compensation
    R rods MI
    n
    rod
    ‚Total R NTC
    Tail "nn + UT
    n
    > RyTtc, total = rod
    In Figure 10 then three different curves 13, 14 and 15 are shown for NTC resistors, the curve 13 shows, for example, a 22K NTC resistor, the curve 14 a 15K NTC resistor and the curve 15 a 10K NTC Resistance. It should be noted that the temperature is shown increasing on the X-axis and the resistance value is shown increasing on the Y-axis. Line 16 is then a threshold value from which an operating device reduces the current output in the inventive arrangement for lighting. This means that in the event that the temperature rises and the resistance value of the NTC resistor falls from the specified threshold value, the operating device reduces the current output accordingly. It is therefore provided that the current output is not immediately adjusted for every slight change in temperature. Rather, the current output is only regulated or reduced accordingly above a certain threshold value, so that a type of protective function can be achieved and circuit boards are operated with reduced power.
    From Figure 10 it can then be seen that when the NTC curve is shifted, the threshold value is reached at a significantly lower or at a significantly higher temperature, which is not intended. A shift in the NTC curve results, for example, when several NTC resistors are connected to one another in series or in parallel. Accordingly, it is sensible and desirable for the temperature-dependent total resistance value to be as constant as possible, which is given by the eight exemplary embodiments shown in FIGS. 1 to 8.
    Overall, it is now possible through the inventive arrangement for lighting that on the one hand, the same boards can be used within an arrangement for lighting, even if the arrangement for lighting is provided for different areas, and on the other hand also whenever possible the same operating device can be used, since it is now possible to determine the number of patins and, based on this, to regulate the current output accordingly.
    [00121] It should also be noted that the lighting means have mostly been described previously as LEDs. However, the invention is not limited to LEDs. Many other types of lighting means, for example OLEDs, would also be conceivable, also in the exemplary embodiments shown in FIGS. 1-8, with OLEDs then using, for example, a corresponding operating device that is suitable for operating OLEDs.
