    CONNECTION TERMINAL WITH BUS OUTPUT CONNECTION FOR PROVIDING DC BUS VOLTAGE FOR AT LEAST ONE OPERATING DEVICE
    The present invention relates to a connection terminal for the electrical connection of bus-compatible operating devices for lighting means, in particular LEDs or OLEDs.
    In particular, the invention also relates to a lamp with such a connection terminal or an operating device which is connected to at least one bus output terminal of the connection terminal.
    The terminal serves in particular as a power supply for at least one operating device, but the network is preferably looped through to the operating device. The power supply unit can provide a certain level at the bus output connection, e.g. an "active low" level for a DALI operating device. According to the DALI standard, the bus is normally live in the idle state. The connection terminal can also contain a logic circuit or a memory unit and / or a control unit (for example IC, ASIC, microcontroller, ... ) and be set up for detecting, evaluating, converting and / or sending signals, preferably DALI or DSI signals.
    An electrical supply provided via a bus is required for bus systems for lighting systems or building technology devices and, in particular, bus-compatible operating devices. The bus is normally supplied with electricity from a central supply in order to supply a large number of operating devices. A manufacturer of bus-compatible operating devices is therefore dependent on the electrical configuration or installation and the specified cable routing. Without an electrical supply via a bus, bus-compatible operating devices cannot generally be used sensibly. This means that it is not possible to use bus-compatible operating devices and, in particular, DALI operating devices separately from an existing installation.
    The aim is to be able to use bus-compatible operating devices by means of the connection terminal according to the invention even when no or no suitable bus cabling, e.g. for communication according to the DALI standard. A connection terminal according to the independent claims is therefore provided. Developments of the invention are the subject of the dependent claims. In addition, a lamp and / or an operating device with a connection terminal are provided.
    In a first aspect, a terminal for the electrical connection of bus-enabled operating devices for lighting is provided, wherein the bus is live in the idle state, and wherein the terminal has input terminals and output terminals for a mains voltage supply, as well as a voltage conditioning unit, which is based on the Input connections for the mains voltage supply is supplied and at least one bus output connection of the connection terminal provides a DC bus voltage for a bus interface of an operating device.
    The bus can be a DALI bus. The at least one bus output connection can be part of a DALI bus interface.
    The at least one bus output connection can be detachably connected to the bus interface of the operating device. The detachable connection can be made using a clamp by means of spring-loaded or fixed pins. The spring-loaded or fixed pins can establish an electrically conductive connection with corresponding connections on the bus interface.
    [0009] The input connections for the mains voltage supply can be releasably connectable to the mains voltage supply.
    [0010] The bus interface can be a DALI bus interface.
    The connection terminal can be a power supply unit.
    [0012] The connection terminal can have several bus output connections for providing a DC bus voltage for several operating devices. Several operating devices can also be connected to the at least one bus output connection. The connection terminal can thus supply a bus system.
    [0013] The connecting terminal can have a memory unit which is set up to store operating parameters of the operating device.
    A connection of the at least one bus output connection of the connection terminal to the bus interface of the operating device can be implemented as a bus, in particular a DALI bus.
    [0015] The connection terminal can be set up to transmit commands, in particular DALI commands, to the operating device.
    After the operating device has been connected, the connection terminal can transmit commands stored in the memory unit to the operating device in response to a user action on a user interface.
    [0017] The voltage conditioning unit can detect an incoming signal at the input connections, in particular a PLC signal. The voltage conditioning unit can provide corresponding signals, in particular DALI signals, at the at least one bus output connection.
    The connection terminal can have a width of 15-55 mm, preferably about 19, 27, 29, 39, or 49 mm, a depth of 20 to 40 mm, preferably about 25 to 35 mm, and a height of 10 -25mm, preferably 16 to 19 mm.
    The connection terminal can have a further bus output connection for connecting a further connection terminal.
    The connection terminal can be connected to at least one DALI control input, a neutral conductor input and a phase conductor input of the operating device and / or the lamp.
    In a further aspect, a lamp or an operating device is provided with a connection terminal as described above, the connection terminal being releasably connectable / connected to the lamp or the operating device, in particular by means of a plug-in, latching, clamping and / or screw connectors.
    The invention will now also be described with a view to the figures. They show: [0023] FIG. 1 a schematic overview of the invention; Fig. 2 schematically shows a detail of the invention;
    [0025] FIG. 3 shows an example of a possible embodiment of the connection terminal according to the invention; and
    Fig. 4 is a sectional view of a housed connecting terminal according to the invention.
    The present invention proposes to provide a connection terminal which allows an electrical connection of bus-compatible operating devices for lighting means.
    The connecting terminal has input connections via which the connecting terminal can be connected to a mains voltage supply and can be electrically supplied. The connection terminal also has output connections, at least one of which is a bus output connection. In addition, output connections are provided which output a mains voltage supply. In this way, the mains voltage supply can be routed or looped through the connecting terminal and fed to the operating device or other devices and / or connecting terminals.
    The connecting terminal furthermore has a voltage conditioning unit which
    starting from the mains voltage supply voltage applied to the input connections, it is electrically supplied and provides a DC bus voltage for a bus interface of a bus-compatible operating device at the at least one bus output connection of the connection terminal. The voltage conditioning unit therefore preferably picks up a line voltage provided at the input connections of the connection terminal and converts this into a bus voltage suitable for bus inputs of the operating device, other devices and / or other connection terminals, in particular a direct voltage or DC bus voltage.
    The voltage conditioning unit can have a rectifier, a filter, a galvanically insulating barrier, a converter or transformer, and a circuit which allows at least one specific level to be output at the at least one bus output connection. Furthermore, the voltage conditioning unit can have a polarity reversal protection circuit in order to ensure that a DC bus voltage of a certain polarity is output at the at least one bus output connection. The reverse polarity protection circuit enables several similar voltage sources to be connected in parallel for the output of the DC bus voltage. The fastest source when starting up can determine the polarity of the sources connected in parallel and thus that of the DC bus voltage.
    The voltage conditioning unit can in particular have a potential-separating SELV barrier, which can be bridged by means of the converter. As a result, areas of the connecting terminal to which a relatively high voltage is applied can be separated from areas to which a relatively low voltage is applied. E.g. contact of a user with the mains supply voltage can be prevented.
    An optocoupler, for example, can be provided for signal return via the galvanically isolating barrier.
    Overall, the connection terminal accepts a mains supply voltage, for example on one side, and also outputs the DC bus voltage on the other side on bus control lines. It can also be provided that the voltage conditioning unit can change a DC bus voltage between at least two levels. For example, Manchester-coded data can then be output at the at least one bus output connection.
    The connection terminal thus also offers the functionality of a power supply unit, on the one hand a connection to the mains voltage supply can be made and on the other hand a bus-compatible and in particular a DALI bus-compatible operating device can be connected to the connection terminal. The connection between the at least one bus output connection and the bus interface of the operating device can be detachable, so that an installed connecting terminal remains at its installation location, while a possibly defective operating device can be replaced.
    The operating device can be connected, for example, by means of a plug, latch or clamp connection, with spring-loaded conductive pins preferably being provided on the connecting terminal, which spring in when the at least one bus output connection is connected to the bus interface of the bus-capable operating device . Electrical contacts of the bus interface of the operating device can be plugged into or into the connection terminal and the conductive pins are brought into contact with the electrical contacts of the bus interface of the operating device in an electrically conductive manner by the action of the spring force. In addition, the connection terminal can be attached to the bus interface of the control gear.
    Of course, other connecting means can also be used in order to establish a connection with the electrical contacts of the bus interface of the operating device. For example, a screw or clamp connection can be used in a similar way to luster terminals. Depending on the configuration of the electrical contacts and / or plugs emanating from the operating device, however, latching connections can also be provided. For example, the connection terminal can be pushed onto a plug provided on the operating device and latched with it. In particular, the connection terminal in one
    Housing to be housed. The housing can be releasably connectable to the operating device or a lamp, likewise by means of a plug, clamp, snap-in and / or screw connection, but e.g. also adhesive.
    On the other hand, the connection terminal can also be releasably connected to the mains voltage supply in a similar manner. For example, if the operating device and / or the connection terminal are fitted in a light, the light including the connection terminal and the operating device can be exchanged and, for example, replaced by another light with a connection terminal and the operating device. It is also possible to just replace the connection terminal individually.
    The connection terminal preferably has a DALI connection interface on the operating device side, so that a suitable DALI bus interface of the operating device can easily be connected to the connection terminal.
    [0039] It is preferably provided that the connection terminal is designed to be relatively small. In particular, their dimensions essentially correspond to known connection terminals such as SLK3 or SLK5. A connection terminal could e.g. a width of 15 to 55 mm, preferably approx. 19, 27, 29, 39, or 49 mm, a depth of 20 to 40 mm, preferably approx. 25 to 35 mm, and / or a height of 10 to 25 mm, preferably 16 to 19 mm.
    The connection terminal is preferably accommodated in a housing which, for example, is similar to a housing of a test adapter.
    Since the connection terminal has to provide relatively little power for the bus and conducts or commutates relatively little power, the connection terminal and the operating device can be contacted by means of the spring-loaded contact pins mentioned above. This also allows flexibility in use and in connection with operating devices. In particular, a tool-free connection and disconnection with the operating device when attaching or removing the connection terminal is advantageous. There is no need to change the existing wiring.
    In one embodiment, the connection terminal supplies components integrated in an operating device. It is also possible for the connection terminal to be designed in such a way that it can supply several operating devices or other components and provides corresponding connections for this purpose. In particular, the connection terminal can have further bus output connections via which more than one operating device can be connected. A DC bus voltage is then also provided at the respective bus output connections. The connection terminal can also supply a bus to which several bus users are connected. In this way, an independent bus system can be set up based on the connection terminal.
    The connecting terminal can have a memory unit and / or a control unit which is set up to store operating parameters and to output them to the at least one bus output connection. The storage unit and / or a control unit can be provided as part of the voltage conditioning unit or separately therefrom. Thus, the connection terminal can establish communication with the at least one operating device, e.g. using the DALI protocol, and thus specify or set operating parameters for the control gear.
    Operating parameters can be stored in the memory unit, e.g. are intended for certain control gear. Thus, after a connected operating device has been identified by the connecting terminal or the control unit, a suitable operating parameter or operating parameter set can be transmitted to the operating device. The connection terminal thus forms its own separate bus system with the operating device, in particular the DALI or DSI requirements. Consequently, a bus and in particular a DALI or DSI bus is implemented between the connection terminal and the operating device.
    If an operating device is defective, the operating device can be replaced and a newly inserted operating device in turn receives the appropriate operating parameters from the
    Terminal transmitted. The connecting terminal can transmit the operating parameter information to the operating device if, on the one hand, the operating device is connected to the connecting terminal and, on the other hand, there is a mains voltage supply at the input connections of the connecting terminal.
    [0046] The commands stored in the memory unit can also be transmitted to the operating device in response to a user action. For example, a user interface, for example a button, switch, push button, ... can be provided on the connection terminal, by means of which a corresponding command transmission is triggered. A user can exchange an operating device and then trigger the transmission of the operating parameters or the commands stored in the memory unit by actuating the user interface.
    On the other hand, it is also possible for the voltage conditioning unit to have a demodulator or a decoding unit in order, for example, to detect a signaling of modulated / coded signals received at the input connections of the connection terminal. The modulated / coded signals can then be evaluated by the voltage conditioning unit and / or the control unit. The recorded coded signals can then be converted into suitable bus commands by the voltage conditioning unit and / or the control unit for communication with the operating device. Communication using a carrier frequency method, for example powerline communication, can be evaluated in detail at the input connections by the voltage conditioning unit or the control unit and, in particular, converted into DALI or DSI commands for the operating device.
    In addition, it can be provided that the connection terminal has further inputs and outputs in order to communicate with further connection terminals. Communication between several connection terminals can thus be enabled via the connection terminals. Connection terminals of different types can be provided, of which, for example, one type is equipped with a memory unit and / or a control unit, while the connection terminals of the other type merely provide a voltage supply for connected operating devices. The connection terminals of the first type can then function as so-called master units, which forward signals and commands to the connection terminals of the other type. In this way, a bus system can be built up gradually and independently of an existing electrical installation. In particular, the connection terminals can communicate with one another. The connecting terminal of the second type then preferably forward data and commands from connecting terminals of the first type to the operating devices, and conversely, information from the operating devices to the connecting terminals of the first type.
    System data such as a bus address, a dimming level or scene information can preferably be stored in the storage unit of the connection terminal.
    Thus, bus-compatible lights and operating devices can be produced by a manufacturer and these can only be adapted to possible installation conditions on site with a connection terminal according to the invention. Appropriate assembly of bus-compatible lights or control gear at the manufacturer is also possible. This enables a smaller number of types of control gear and lights to be manufactured. In particular, it should be noted that the connection terminal can also be plugged directly onto a bus interface of the operating device and can be held there by means of corresponding latching, clamping, plug-in or screw connections. The connection terminal therefore also allows operating devices from different manufacturers to be used, for example.
    As a power supply unit, the connection terminal is thus connected to the operating device at its bus interface and can also be pulled off or removed from it again without any obstacles. The aim is to keep the housing for the connection terminal as small as possible.
    Fig. 1 shows a schematic overview of the invention. A connection terminal 1 and an operating device 2 are shown, which are supplied from output connections 16 of connection terminal 1 and are connected to bus output connection 3. Schematic
    a storage unit 4, a control unit 5 and the voltage conditioning unit 6 are also shown in the connection terminal.
    It is also shown by way of example that the connection terminal 1 can also supply electrical power to a further operating device 7 via a further output interface 8. It is also schematically indicated that the connection terminal 1 can be connected to a further connection terminal 9, via which a third operating device 10 is in turn electrically supplied. Bus communication can then take place between the connection terminal 1 and the second connection terminal 9, in particular via a bus and preferably via a DALI or DSI bus. The connection terminal 1 can therefore have a terminal connection 11, while the second connection terminal 9 has a corresponding terminal connection 12. The bus connection between the connection terminal 1 and the second connection terminal 9 is indicated by the dotted lines. Commands delivered from the connection terminal 1 to the second connection terminal 9 can then be passed on from the second connection terminal 9 to the third operating device 10 (dotted lines).
    Between the terminals 1, 9 and the operating devices 2, 7, 10 each 5 connection lines are shown, which for a connection of connections N (neutral conductor), L (outer conductor, phase), and PE (protective conductor, protective earth) and the bus connections DA + and DA between the respective connection terminal 1, 9 and the respective operating device 2, 7, 10. It should be understood that a PE conductor can also be connected to the input connections in addition to N and L conductors. If bus cabling is already installed, the connection terminals 1, 9 can also loop through bus signals. This is also clear below with reference to FIG. 2.
    In Fig. 1, the bus interface of the operating device 2 is exemplarily denoted by 14 and includes bus inputs of the operating device 2 and inputs for the mains voltage supply. The input connections of the connection terminal 1 are denoted by the reference symbol 15 and comprise the input connections for the mains voltage supply and / or bus connections. The output connections of the connection terminal 1 are denoted by the reference number 16 and comprise the output connections for the at least one bus output connection 3 and for the mains voltage supply.
    Commands stored in the memory unit 4 can be sent both to the operating devices 2, 7 connected to the connection terminal 1 and to the second connection terminal 9 optionally connected to the connection terminal 1. The second connection terminal 9 can then forward the data and / or commands received from the connection terminal 1 to the third operating device 10 while the third operating device 10 is supplied with voltage through the second connection terminal 9.
    It is also shown in FIG. 1 that the connection terminal 1 and the second connection terminal 9 can be supplied from different voltage sources. The second connection terminal 9 therefore has a voltage conditioning unit 13, from which the third operating device 10 can be supplied with a DC bus voltage.
    In the following, the reference symbols introduced with FIG. 1 will continue to be used.
    2 shows schematically in an overview how the connection terminal 1 can be connected to an operating device 2 or a bus and a mains supply. The input connections 15 of the connection terminal 1 are connected to a phase conductor or outer conductor L and a neutral conductor N, and optionally to a protective conductor PE.
    On the other hand, the at least one bus output terminal 3, e.g. the (DALI) bus connections DA + and DA-, also connected to the operating device 2, in addition to the N, L, PE connections. The voltage conditioning unit 6 picks up the voltage on the outer conductor L and the neutral conductor N of the input connections 15 in order to output a correspondingly converted DC bus voltage at the at least one bus output connection 3 of the output connections 16, here at the bus connections DA + and DA-.
    3 shows a more detailed view of the connection terminal 1 and the voltage conditioning unit 6. The voltage conditioning unit 6 can filter a voltage tapped at the phase conductor L and the neutral conductor N of the input connections 15 by means of an electromagnetic interference filter (EMI filter) 20 . A rectifier 21 and a converter 22 are also shown. The converter 22, here a transformer, bridges a galvanically insulating barrier 23. A first control circuit 24 is provided on the primary side of the barrier 23. A second control unit 25 is shown on the secondary side of the barrier 23. The second control circuit 25 can control a circuit arrangement 26 such that an electrical supply of the bus is ensured at the bus output connection 3. The connection terminal 1 can also forward incoming bus commands via the connections DAIN +/-, DAIN - / + to the at least one bus output connection 3 and in particular have connections for receiving DALI signals. Furthermore, the voltage conditioning unit 6 can have the optocoupler 27 already mentioned above, in order to enable signals to be fed back from the secondary side to the primary side in an isolated manner. A reverse polarity protection circuit can also be provided in order to ensure a specific polarity of the output DC bus voltage.
    A more specific embodiment of the connection terminal 1 is shown in FIG. 4 as a sectional view with a housing 30. Also shown is part of a lamp or operating device housing 31 on which the connecting terminal 1 is attached with an exemplary latching connection (latching hook) 32. A bus interface 14, 34 of the lamp or of the operating device is also shown, onto which the connecting terminal 1 is pushed. Spring-loaded contact pins 35 serve as electrically conductive connectors between the connection terminal 1 and the bus interface 14, 34 of the operating device or the lamp. The contact pins 35 connect at least the secondary-side circuit steeply electrically to corresponding interface connections DA +, DA- of the bus interface 34. A circuit board 36 of the connection terminal 1 is also shown.
    When the connection terminal 1 is attached to the bus interface 14, 34 of the lamp or the operating device, the spring-loaded contact pins can spring in and press with a spring force onto the corresponding interface connections DA +/-, DA - / +. For example, fixed contact pins can also be used, which are then pressed into the contacts to be contacted. This creates an electrically conductive connection. When the connection terminal 1 is removed, the contact pins spring out again.
    In the same way, a mains voltage supply between the interface connections N, L and PE of the lamp or the operating device and the corresponding output connections 16 of the connection terminal 1 can be established. When the mains supply voltage is passed through to the light / operating device or when the light / operating device is electrically supplied, contact is made to contacts N and L as well as PE of bus interface 14, 34.
    It can also be provided that a mains supply of the lamp / the operating device, which is used to supply the lamp / the operating device, is looped through to supply the connection terminal 1. In addition, it is to be understood that bidirectional communication can take place between the connection terminal 1 and the operating device 2.
