    LIGHTING ARRANGEMENT WITH OPERATING DEVICE FOR PROVIDING A SUITABLE SUPPLY CURRENT
    The present invention relates to a lighting arrangement according to the preamble of claim 1, which has lighting means and an operating device, wherein the operating device provides a suitable supply current for the lamps. The lighting means are part of a releasably connected to a holder of the lighting arrangement lamp unit, wherein the operating device adjusts the supply current depending on the lighting unit.
    Compared to traditional bulbs such as light bulbs or fluorescent lamps LED-based bulbs allow a more flexible use in lighting technology. While in the past luminaires could only be equipped with a specific illuminant, for example a fluorescent lamp of a certain size and power class, replaceable LED-based illuminant units, which, however, have a specially adapted luminaire, are often used in lighting arrangements Need supply current. The reason for this is that, for example, to achieve a uniform, uniform light output, the currents provided to the LEDs must be specially adapted. However, since the LEDs themselves are subject to certain fluctuations during their production, for example, an identical required supply current or an identical supply voltage does not generally result for an LED module. This in turn means that the operating devices for providing a corresponding supply current for such LED modules must be able to vary this current, at least within a certain bandwidth.
    However, it is not only necessary that the operating device is able to variably provide a supply current available, but also that the operating device itself knows what requirements for the supply current and the supply voltage exist.
    A first way to solve this problem is in a manual approach. In this case, the operating device is accordingly programmed or parameterized before the luminaire is put into operation. However, this means that during the later operation of the supply current is no longer changed by the operating device and accordingly a change eg. A defective LED module can only be done if the new module has identical requirements in terms of supply current. However, a change, for example, on a module with modern LEDs, which require a different supply current, is not possible in this case.
    An alternative approach, which is also known from the prior art, therefore, provides to provide the replaceable lamp module with an identification element. This is usually formed by a resistor which characterizes by its resistance value the module or the supply current required by the module. By means of special connections, this resistor, which is not part of the actual circuit with the lighting means, is then coupled to the operating device and, after the resistance value has been identified, it can adapt the supply current for the lighting devices accordingly.
    Although this known from the prior art approach by which an automatic adjustment of the supply current can be ensured, is often used, but in this case it is necessary that the lamp module has additional connections in addition to the terminals for the power supply , via which a corresponding connection of the identification resistor to the operating device is made possible. This not only leads to a more complex design of the lamp module, but also to an increased effort when arranging or mounting the module to the lighting
    Order.
    The present invention is therefore based on the object to offer a novel solution, which still ensures that the supply device automatically provides a tuned to the needs of the lamp module supply current, on the other hand, however, to a simplified embodiment of the illuminant Module leads.
    The object is achieved by a lighting arrangement having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
    The solution according to the invention is based in turn on the idea of characterizing the lighting unit or the supply current required by the lighting unit by at least one electrical component which is coupled to the operating device and identified by this. In contrast to previously known solutions, in which the electrical element was part of the replaceable lamp unit, it is now provided, however, that the electrical element is part of an identification circuit, which is not part of the lighting unit. Instead, the identification circuit is connected to the operating device and part of a circuit arrangement with a plurality of electrical elements, which can optionally be added to the identification circuit. The replaceable lamp unit interacts with the circuit arrangement in such a way that in a state of the lamp unit arranged on the holder of the lighting unit, a combination of the electrical elements characteristic of the lamp unit is added to the identification circuit.
    According to the invention, therefore, a lighting arrangement with light sources and an operating device for providing a supply current for the bulbs is proposed, wherein the bulbs are part of a releasably connectable to a holder of the lighting arrangement lamp unit and wherein the operating device is designed, depending on a Bulb unit characterizing property of an identification circuit to provide a suitable supply current. The lighting arrangement according to the invention is characterized in that the identification circuit is part of a circuit arrangement with a plurality of electrical elements, which can optionally be added to the identification circuit, wherein the lighting unit cooperates with the circuit arrangement such that in a arranged on the holder of the lighting arrangement state of Lamp unit is a characteristic of the lighting unit combination of electrical elements part of the identification circuit.
    The illuminant unit identifying elements, which in turn is preferably in turn one or more resistors are now so directly part of the lighting arrangement, but not part of the interchangeable lamp unit. The circuitry comprising these electrical elements, however, allows either individual ones of the electrical elements to be added to the identification circuit by the lighting unit in the mounted state. This avoids that in addition to the connections for the power supply, the lamp unit must also be electrically connected to the operating device. Furthermore, the individual electrical elements can be selected better matched to the operating device, so that, if necessary, a more reliable and accurate identification of the lighting unit is made possible.
    The optional addition of the electrical elements to the identification circuit is preferably carried out in that each of the elements is assigned in each case a switching element, by which the corresponding element can be added to the circuit or separated from it. In a simple way, in this case, for example, all the individual electrical elements are connected in parallel to one another, wherein the respective branch can then optionally be interrupted or closed by a switching element. As an alternative to this, however, the electrical element could also be short-circuited or bridged by a corresponding switching element, so that, in turn, it is effectively not part of the identification circuit.
    Preferably, it is provided that the interaction between the lamp unit and the circuit arrangement is such that the lamp unit operates contactlessly the corresponding switching elements. This could, for example, be effected by the lighting unit having magnetic elements matched to the positions of the corresponding switching elements and the switching elements being formed by reed contacts cooperating with these magnets. When inserting or mounting the lamp unit to the support of the lighting arrangement, the corresponding magnets are then automatically positioned in the immediate vicinity of the corresponding reed contacts, so that then the associated electrical elements are added according to the identification circuit.
    Alternatively to the non-contact variant described above, however, a mechanical alternative would be conceivable in which the lamp unit corresponding projections or pins are formed, which then selectively actuate the corresponding switching element mechanically.
    As part of a larger lighting arrangement can be provided that are supplied by the operating device several replaceable lamp units with power. In this case, it should preferably be in each case to similar lighting units, each requiring an identical supply current. An identification of each individual lighting unit is then not required in this case. Instead, it is preferably provided that only for one of the lamp units, a corresponding mounting position is provided, in which the inventive cooperation with a circuit arrangement that includes the identification circuit, is provided. That is, this particular lighting unit serves to identify and ensure the power supply to all the lighting units.
    The invention will be explained in more detail with reference to the accompanying drawings. In the drawings: FIG. 1 shows a lighting arrangement with an operating device as well as several replaceable lamp units supplied by the operating device; Figure 2 shows a simple variant of a circuit arrangement, which has a
    Identification circuit includes; Figures 3a and 3b show an embodiment of an inventively with the scarf processing arrangement cooperating light source unit and Figures 4a to 4d are schematic representations to illustrate the operation of the embodiment of Figure 3.
    Figure 1 shows first as a conceivable application example of the present invention, an elongated, generally provided with the reference numeral 100 Lichtbandsystem. This consists initially of an elongated support assembly 101 consisting of several, successively arranged support rails 102, which are arranged, for example, by means not shown mounting elements directly on a ceiling or suspended from a ceiling. These support rails 102 are preferably connected to one another in an elongated arrangement and serve as central support elements for the entire arrangement 100. In particular, the support rails 102 serve to hold the individual illuminant units described below in more detail and the components for powering these units. For example. Therefore, such mounting rails 102 are U-shaped in cross-section and open at the bottom, so that from the bottom of the corresponding receiving space of the support rails 102 is accessible.
    [0022] In the present case, only a schematic representation of the way in which the current
    Supply of the replaceable lamp units 50 takes place. So far, it has been known that run within the support assembly 101 power supply lines, which could be contacted either at any point or at certain predetermined positions by the exchangeable lamp units 50 to be arranged. These power supply lines provided the normal power supply voltage available, which then had to be implemented by appropriate operating devices of the individual lamp units in a suitable manner. In this hitherto known solution, it was therefore necessary for each lighting unit 50 to have its own operating device, for example a converter for converting the general mains supply voltage into a supply current suitable for the lighting means.
    In contrast, it is provided in the solution shown in Figure 1 that not every bulb unit 50 has its own operating device, but instead several units are supplied centrally from a common operating device 20. In the illustrated embodiment, subgroups of lighting unit 50 are provided for this purpose, wherein an operating device 20 per support rail 102 is provided. Only this operating device 20 is connected to the - not shown - power supply lines to which the general mains voltage is applied. On the output side of the operating device 20, however, extends a further power supply circuit 25 to which a suitable for the light-emitting device 50 supply current is already applied. In this case, the illuminant units 50 thus do not require their own operating devices, but only have to be connected to the output circuit 25, which is effected by providing corresponding contacting plugs or sockets 30 at certain predetermined positions, which provide a corresponding coupling with corresponding negative feedback elements 51 Enable light modules 50. That is, each Kontaktierungsbuchse 30 of the output circuit 25 allows the connection of a lighting unit 50, which is then supplied by the operating device 20 with power. The cost of implementing the illustrated lighting system 100 is correspondingly lower because the number of required equipment can be significantly reduced.
    To ensure that the light sources of the individual lamp units 50 are actually supplied with a suitable supply current, it must be ensured, as described above, that the operating unit 20 has or knows the type of the connected lamp unit 50 What is actually needed for a supply current. With the invention described in more detail below, this problem is solved.
    Basically, the concept according to the invention is based on the idea of evaluating the electrical properties of an identification circuit and, based thereon, of identifying the connected lighting unit 50. Schematically, a corresponding identification circuit is shown in FIG. This generally designated by the reference numeral 10 circuit has two input-side terminals and a plurality of parallel resistors R1, R2 and R3. As is known from the prior art, it is provided to characterize the lighting unit by the height of a resistor, but now not a single resistor is used, but the total resistance of the identification circuit 10 is used. It is provided here that at least some of the resistors R1 to R3 are only added to the identification circuit if necessary. In the illustrated embodiment, it is the two resistors R2 and R3. As shown, these two resistors R2, R3 are each assigned a switching element S1 or S2, by which the corresponding branch in which the resistor R2, R3 is arranged, can be opened or closed. Depending on the state of these switching elements S1 and S2 thus results in a parallel circuit consisting exclusively of the permanently connected resistor R1 or a combination of the resistor R1 with one or two of the further resistors R2 and R3. By applying a known voltage to the terminals of the identification circuit 10, it can then be determined from the resulting current flow which resistors have been added by the switching elements S1, S2. The combination of these resistors then characterizes the corresponding lighting unit and based on this information, the operating equipment can then provide a suitable current.
    The peculiarity of the inventive solution consists in the fact that the or the resistors R1 to R3 of the identification circuit 10 is not - as usual - a component of the replaceable lamp unit, but instead all components of this circuit permanently or in the Support rail 101 arranged and fixedly coupled to the operating device 20.
    That is, it is not necessary to connect the operating device 20 in addition to the lighting unit 50 as before, to read an identification resistor.
    However, now the illuminant units 50 are enabled, when arranged on the mounting rail 101 in such a way with the circuit arrangement, which includes the identification circuit 10, cooperate, that the resistors R2 and R3 in a characterizing for the lamp unit 50 Way be added to the identification circuit 10. A conceivable variant for this is shown in FIGS. 3a and 3b.
    Figure 3a shows this schematically in plan view the coupling region of the support rail 102 to which a lighting unit 50 can be arranged. In this case, corresponding connections 15 to 17 are provided centrally for connection to the power supply lines of the output circuit 25 and possibly to ground the connected lighting unit 50. In the peripheral region of these connections 15 to 17, however, a circuit board 20 is now arranged, on which the above-mentioned identification circuit 10 is formed. The corresponding interconnects of this circuit are not shown for reasons of clarity. However, the terminals of the identification circuit and the resistors R1 to R3 are shown with the associated switching elements S1 and S2. As mentioned, these elements are connected via the printed conductors, not shown, to the circuit arrangement as shown in FIG.
    According to a preferred embodiment of the invention, it is now provided that the switching elements S1 and S2, which are activated or deactivated by the lighting unit 50 in a corresponding manner, executed such that a non-contact interaction takes place. This can be realized in a particularly preferred manner in that the switching elements S1 and S2 are formed by reed contacts, that is to say elements which interact with magnetic elements. As can be seen from the side view of FIG. 3b, these reed contacts S1 and S2 are arranged on the circuit board 20 in such a way that they are located in the immediate vicinity of the illuminating unit 50 arranged on the support rail 102.
    In this case, the lighting unit 50 or its coupling element 51 initially has corresponding contacting elements 55 to 57, which interact with the contacts or sockets 15 to 17 of the connection region. In addition, however, the light-emitting device 50 characterizing magnets are provided, which cooperate with the reed contacts S1 and S2. In the illustrated embodiment, in the area of the lighting unit 50, which is located immediately after mounting on the mounting rail 102 in the vicinity of the reed contact S2, a permanent magnet M2, which cooperates in the assembled state with the reed contact S2 , That is, when attaching the lamp unit 50 to the support rail 102, the resistor R3 is automatically added to the identification circuit 10 and the circuit 10 has a total resistance corresponding to a parallel connection of the resistors R1 and R3. By evaluating the current flow resulting in the identification circuit 10 resulting therefrom, the operating device can then identify the lighting unit 50 and output a supply current of suitable height.
    Obviously, the resistors R2 and R3 can be added to the circuit 10 in four different variants in this approach. These variants are shown schematically in FIGS. 4a to 4d, wherein FIG. 4a corresponds to the variant illustrated in FIG. 3b. In contrast, in the variant according to FIG. 4b only the resistor R2 is connected via the reed contact S1 and the magnet M1, whereas in the variants of FIGS. 4c and 4d both or none of the resistors R2 and R3 are added. In all these four variants results in a different total resistance for the identification circuit 10, so that in this embodiment, four different light-emitting device 50 can be identified.
    Of course, it would be conceivable to arrange the resistors, which can optionally be added to the identification circuit, as well as their switching elements S1 and S2 otherwise. For example. would also be a parallel connection between the switching element and the associated resistor conceivable, in which case the corresponding resistor is bypassed, so that it is effectively no longer part of the identification circuit. In this case, however, then the resistors should be arranged serially, and in principle more complex circuit arrangements would be conceivable.
    Furthermore, it would also be conceivable to use other electrical elements instead of the resistors, which contribute to a change in the overall characteristics of the identification circuit. Also conceivable would be, for example, the use of inductors or the like, although here then the evaluation would be more expensive, so that the illustrated variant is certainly preferable.
    Finally, not necessarily a non-contact interaction between the switching elements and the lamp unit to be connected must be provided. It would also be conceivable that the switching elements are mechanically actuated by the lamp unit. In this case, corresponding protrusions or pins would then have to be provided on the outside of the lighting unit 50, by means of which the switching elements can be selectively actuated.
    In the embodiment shown in Figure 1, of course, must not take place at each contacting possibility of a single support rail corresponding identification of the connected lighting unit. Preferably, only at the first position, a corresponding circuit arrangement, which cooperates in the manner according to the invention with the light-emitting unit, is provided. Only this lighting unit is then identified by the operating device and the output power supply is adapted to this identified unit. This is acceptable, since ideally identical illuminant units should in each case be arranged on a mounting rail in order to be able to achieve a uniform light output over a greater length in the illustrated exemplary embodiment.
    Finally, it should also be noted that the concept of the invention could of course be used not only in the illustrated embodiment of an elongated lighting system. In the same way, the concept could also be realized in individual luminaires, which have one or more releasably securable lighting modules, which are arranged on a support element of the luminaire. Such a procedure has been proven, since this single modules, where defects in the bulbs auftre-th, can be changed easily. In this case too, however, the advantage is achieved that the luminaire still requires only a single operating device and, in spite of all, in a simple manner automatically provides a suitable supply current for the luminous-element units.
