    description
    The invention relates to a lighting arrangement with a two-pole power distribution system and at least one lamp connected to the power distribution system, as well as a power supply device connected to the power distribution system via a control device, the control device being coupled to a sensor unit to provide information about an operating state to be set of the at least one To transmit lamp from the sensor unit to the control device.
    Lighting arrangements with such a power distribution system are used, for example, in the furniture sector in order - preferably several - to supply lamps via the power distribution system with power and to be able to change their operating state via the sensor unit as a group. The sensor unit can have a wide variety of sensors that detect their surroundings and control the control device and thus the lamps as a function of the detected variables. Sensors can be, for example, touch or proximity sensors that detect an actuation by a user. In this sense, manually operated buttons or switches are also to be regarded as sensors.
    The operating state relates, for example, to switching the lamps on or off and, if necessary, dimming them. A power rail is preferably used as a power distribution system, on which the lamps can be arranged in any position. A lighting arrangement with such a power distribution system is known, for example, from the publication DE 20 2012 103 637 U1.
    The sensor unit can transmit control signals relating to the operating state of the lamps, for example by radio, to the control device, which then adjusts the power supply to the power distribution system according to the desired operating state of the lamps. This can involve switching the power supply for the lamps on or off or a variation of the (mean) current or voltage, for example in a pulse width modulation process (PWM) for dimming the lamps.
    In a mobile sensor unit, e.g. B. a so-called remote control, a battery is usually used to power the sensor unit. Often, however, the sensor units are stationary, for example attached to furniture, in which case a power supply via the power supply device already present in the lighting arrangement is desirable in order to be able to dispense with the batteries to be replaced.
    In principle, a power supply for the sensor unit via the power distribution system would be practical in many cases. However, it is not possible in the case of lighting arrangements according to the prior art, since in a switched-off operating state of the lamps or in a heavily dimmed operating state of the lamps, the sensor unit would not be adequately supplied via the power distribution system. It is therefore necessary to position the sensor unit directly integrated into the control device, or to supply it via a separate cable running from the power supply device or the control device to the sensor unit.
    It is an object of the present invention to provide a lighting arrangement of the type mentioned in which a sensor unit for controlling the control device can also be arranged without a separate cable and away from the control device or the power supply device.
    This object is achieved by a lighting arrangement having the features of the independent claim. Advantageous refinements and developments are the subject of the dependent claims.
    A lighting arrangement according to the invention of the type mentioned is characterized in that the control device applies a voltage of alternating polarity to the power distribution system, the at least one lamp being set up so that it is only supplied with operating current at one polarity of the voltage, whereas the sensor unit is set up in such a way that it is supplied with operating current for each polarity of the voltage.
    In this way, depending on the polarity of the voltage that the control device sets, the at least one lamp can be switched on or off, with operating current for supplying the sensor unit being available in each of these operating states. In the case of rapidly changing polarity, the brightness of the at least one lamp can also be adjusted via pulse width modulation, with operating current being available for the sensor unit for every degree of brightness. The sensor unit can thus be supplied via a 2-pole power distribution system, even if it does not transmit any operating current to the at least one lamp.
    In an advantageous embodiment of the lighting arrangement, the at least one lamp has a light source with an upstream half-wave rectifier, e.g. a diode. Alternatively, the at least one lamp can have a lighting means with an integrated or an inherent diode, for example a light-emitting diode. The upstream or integrated or inherent diode ensures that the lamp is only operated with one polarity. In contrast, the sensor unit comprises a full-wave rectifier or one is connected upstream of it. The full-wave rectifier supplies the sensor unit with operating current for both polarities of the voltage on the power distribution system. In order to avoid short-term voltage interruptions when changing polarity, a buffer capacitor is preferably connected downstream of the full-wave rectifier.
    In a further advantageous embodiment of the lighting arrangement, the control device has a bridge for providing the voltage with the alternating polarity. The voltage with the alternating polarity can be generated from a supplying direct voltage via the H-bridge. With suitable control, the
    Voltage with the changing polarity can also be provided in a pulse-width-modulated manner in order not only to be able to switch the at least one lamp on and off, but also to be able to dim it.
    In a further advantageous embodiment of the lighting arrangement, the power distribution system comprises a busbar with which a user can flexibly position one or more lamps and the sensor arrangement.
    The sensor module can have an optically and / or acoustically operating distance sensor, whereby it can function as a contactless switch for the lighting arrangement. However, other sensors, for example an infrared motion sensor, a brightness sensor or a temperature sensor, can also be used in order to control the at least one lamp as a function of ambient conditions. In order to transmit control signals that relate to the operating state to be set of the at least one lamp to the control unit, the sensor module can have a radio module. Alternatively, wired transmission or transmission via the power distribution system by modulating the signals to the operating voltage is also possible.
    The invention is explained in more detail below using an exemplary embodiment with the aid of figures. The figures show:
    1 shows a block diagram of a lighting device according to the application; and
    2 shows a schematic representation of a time curve of a supply voltage within the loading
    lighting arrangement according to FIG. 1.
    1 shows, in a schematic block diagram, an exemplary embodiment of a lighting arrangement according to the application.
    The lighting arrangement comprises a power supply unit as a power supply device 1, which is connected to the lighting network via connections not shown here. The power pack provides a DC extra-low voltage at its output, for example 12 or 24 volts (V). This direct voltage is fed to a control device 2, the output of which is connected to a two-pole power distribution system 3. In an alternative embodiment of the lighting arrangement, the control device 2 can also be integrated into the power supply device.
    The power distribution system 3 is, for example, a busbar that can be used in connection with a piece of furniture, for example a cabinet. The course of the voltage with which the control device 2 acts on the power distribution system 3 is explained in more detail in connection with FIG. 2.
    Four lamps 10 are connected to the power distribution system 3 here by way of example. In the case of a busbar as the power distribution system 3, the lamps 10 can be used by the user in the desired number and in the desired position. For example, a glass showcase can be illuminated with the aid of lamps 10 and a power distribution rail arranged in the interior of the showcase. The lamps 10 are supplied with operating current by the control device 2 via the power distribution system 3. Furthermore, in the example shown, a sensor unit 20 is connected to the power distribution system 3. The sensor unit 20 is also supplied with operating power via the power distribution system 3. This is also explained in more detail below in connection with FIG. 2.
    The sensor unit 20 is coupled to the control device 2 via a radio link 25. Signals relating to an operating state of the lamps 10 are transmitted via this radio link 25; specifically, whether the lamps 10 are switched on or off and, optionally, with what degree of brightness in the range of 0-100% the lamps 10 are operated. The switch-on state or the degree of brightness is set by the control device 2 for all lamps 10 in the same way via the (average) current or the voltage with which the current distribution system is applied to the power distribution system 3.
    The radio link 25 can take place, for example, in accordance with the Zigbee or one of the known Bluetooth protocols. Alternatively, control signals can also be transmitted from the sensor unit 20 to the control device 2 via the power distribution system 3 by modulating corresponding signals onto the voltage in the power distribution system 3. Such a signal transmission method is also known as powerline transmission. Finally, wired transmission of the control signals would also be conceivable.
    The sensor unit 20 has a sensor 22 which is coupled to a microcontroller 23. The microcontroller 23 is in turn connected to a radio module 24 which provides the signal for the said radio link 25. The sensor 22 is, for example, a distance sensor that operates optically or by means of ultrasound. A finger of a user can be detected without contact via this. If the finger approaches the sensor 23 or if the finger is placed on the sensor 23, this is recognized as an actuation signal for the sensor unit 20. Depending on whether a short tap or a longer touch is provided, this is interpreted as a signal for switching the lamps 10 on / off or as a signal for changing the degree of brightness (dimming) of the lamps 10. The microcontroller 23 then outputs a corresponding signal via the radio module 24 and the radio link 25 to the control device 2.
    In alternative configurations of the sensor unit 20, sensors other than the aforementioned distance sensors can also be used. For example, infrared movement detectors can be used so that the lamps 20 are switched depending on a detected movement in the room. Furthermore, as part of the registration
    a manual button can also be used as a sensor 22, via which the lighting arrangement can be operated. A temperature or brightness sensor can also be used to control the lighting arrangement. The sensor arrangement 20 can be arranged in such a way that it reacts to impulses from a user. It can also be provided that the sensor unit 20 is positioned such that, for example, an open state of a cabinet door is used to control the lighting arrangement.
    According to the application, the sensor unit 20 is supplied with operating current via the power distribution system 3, even if the lamps 10 are provided with no operating voltage or only such a low operating voltage that would not be sufficient to operate the sensor unit 20 via the power distribution system 3.
    This is achieved in that the control device 20 gives a supply voltage to the power distribution system 3, which can switch between two polarities, the lamps 10 being operated only with one of the polarities of the supply voltage, whereas the sensor unit 20 is operated by both polarities the supply voltage is supplied with energy.
    2 shows the level of a supply voltage U as a function of a time t with which the power distribution system 3 is acted upon by the control device 2. The voltage U changes its polarity periodically from here + 12V to -12V within a period tc. The period tc is selected to be so short that even with small brightness levels set, flickering of the lamps 10 is preferably not noticeable. The period tc is in a range that corresponds to a frequency of, for example, 1 kilohertz (kHz) or more.
    Such a voltage curve can be generated from the direct voltage supplied by the power supply unit, for example via a correspondingly controlled H-bridge circuit. In time segments tx, the voltage U has a positive polarity. In further time segments ty the polarity of the voltage U is negative.
    The lamps 10 include a half-wave rectifier 11 and a lamp 12. Due to the half-wave rectifier 11, only one of the polarities, for example the positive polarity in the time segment tx, reaches the lamp 12. Thus, only the time segments tx are relevant for the operation of the lamps 10 .
    The sensor unit 20, on the other hand, is supplied with operating current via a full-wave rectifier 21, so that the sensor unit 20 is supplied with operating current both in the time segments tx and in the time segments ty.
    The time curve of the voltage U shown in Fig. 2 represents an operating state of the lamps 10 at a brightness level of 50%. Correspondingly, the lamps 10 are only supplied with power for half of the period tc, in that tx = ty = t0 / 2 is set. Greater brightness can be set by the control device 2 if the time segment tx is extended in favor of the time segment ty, up to a situation in which tx = tc and ty = 0. In this case, only a positive voltage U is output. Conversely, the degree of brightness can be selected to be less than 50% if the time segment tx is shortened in favor of the time segment ty, up to a situation in which tx = 0 and ty = tc and the lamps 10 are switched off accordingly. In every operating situation, due to the full-wave rectifier 21 of the sensor unit 20, the full operating voltage is available.
    The half-wave rectifier 11 is shown in FIG. 1 as a diode which is connected upstream of the lighting means 12. If the lighting means 12 is a light emitting diode (LED), such a one-way rectification is inherently provided, so that a separate upstream diode is not necessary.
    The full-wave rectifier 21 is shown symbolically in FIG. 1 as a Graetz bridge with four diodes. In order to prevent a drop in the supply voltage for the sensor unit 20 when the polarity is changed when the voltage U changes, a buffer capacitor is generally additionally connected in parallel to the output of the full-wave rectifier 21.
