    description
    OPERATING DEVICE WITH TEST SWITCH AND STATUS DISPLAY
    The invention is in the field of emergency lighting and relates in particular to an arrangement comprising an operating device for emergency lights with a test switch and a status display and a corresponding emergency lighting.
    For emergency lighting systems operating devices (ballasts) are used for the operation of connected lights with an additional power supply, which ensures the operation of the connected lights for a predetermined period of time even if the mains power supply fails. In the event of a failure of the primary mains power supply, the power supply is maintained for a rated operating time by means of energy stored in accumulators, in order to enable people with a certain illuminance to leave a building, for example, over the rated operating time.
    The functionality of the emergency lighting is to be checked at regular intervals as part of function tests as well as continuously during operation as part of self-tests. Such a function test is triggered, for example, by pressing a test switch (test button) connected externally to an emergency lighting operating device. The test switch is connected to the emergency lighting operating device with two wires, often by means of plug connectors, and therefore requires two externally accessible connection options on the emergency lighting operating device.
    The operating status (status) of an emergency lighting system is usually signaled externally. For this purpose, a green light-emitting diode (LED) can signal that the emergency lighting system is ready for operation, while a detected fault in the emergency lighting system is signaled by means of a red LED. Conventional operating devices therefore each have at least two further external connections for the LEDs for status display.
    Thus, operating devices for emergency lighting systems have at least six external connections that require the corresponding space in a housing and corresponding expense in the wiring as part of the installation of an emergency lighting system.
    The invention is therefore based on the object of reducing the complexity of an operating device for emergency lighting systems.
    The object is achieved by an arrangement of an operating device and a first light emitting diode, a second light emitting diode and a test switch, which has the features of independent claim 1, and an emergency lighting according to the invention.
    The arrangement comprises an operating device for emergency lighting, a first light-emitting diode, a second light-emitting diode and a test switch. The arrangement is characterized in that the operating device comprises a first connection and a second connection, the first light-emitting diode and the second light-emitting diode being connected in opposite directions in parallel between the first connection and the second connection. The test switch is preferably connected in parallel to the first light-emitting diode and the second light-emitting diode and is set up to short-circuit the first connection to the second connection when actuated.
    The arrangement according to the invention reduces the number of necessary external connections of the operating device to only two in total compared to the original six connections. The installation space requirements for the housing of the operating device are accordingly reduced. Because there are no connections, for example sockets or terminals, the unit costs of the individual control gear are also reduced. The cabling effort for the operating device is also reduced due to the reduced number of lines to be connected, which is reflected in reduced installation costs. The reduced number of external connections allows more degrees of freedom for the design of the housing of the control gear.
    [0010] Further advantageous developments of the invention are the subject of the dependent claims
    claims.
    A preferred arrangement has the operating device with a constant current source, wherein the constant current source is designed to impress a constant current with a first or with a second polarity opposite to the first polarity between the first connection and the second connection.
    An advantageous arrangement according to the invention comprises the operating device with a control circuit, the control circuit being designed to detect a short circuit between the first connection and the second connection.
    The arrangement according to an advantageous embodiment comprises a control circuit of the operating device, wherein the control circuit is designed to detect a short circuit between the first connection and the second connection by determining that for a limited constant current between the first connection and the second Connection a voltage between the first connection and the second connection falls below a limit value.
    One embodiment of the arrangement according to the invention has the control circuit designed to determine a short circuit between the first connection and the second connection on the basis of a control parameter of the constant current source, in particular on the basis of a clocking of a switch of the constant current source.
    Another arrangement according to an embodiment shows the control circuit designed to control the constant current source so that either the first constant current with the first polarity or the second constant current with the second polarity is impressed between the first terminal and the second terminal.
    Another embodiment of the arrangement according to the invention is characterized in that the constant current source is designed to switch between the first current of the first polarity or the second current of the second polarity. The constant current source can comprise a first constant current source and a second constant current source, wherein the first or the second constant current source can alternatively be switched to the first connection and to the second connection.
    In a particularly preferred embodiment of the arrangement according to the invention, the first light-emitting diode, second light-emitting diode and the test switch are implemented in an integrated manner in a common assembly, in particular in a common assembly housing.
    Thus, compared to the usual, separately executed test button on the one hand and status displays on the other hand, a reduced number of units for the arrangement according to the invention is achieved, which is possible and particularly advantageous due to the inventive reduction to two compared to the original six connections. The two connections via the first connection 9.1 and the second connection 9.2 from the operating device 1 to the assembly can be formed, for example, by means of plug connectors or as crimp connections. Thus, the logistics are reduced by the correspondingly lower number of separately managed components, the costs for the component production of the emergency lighting system, and the costs associated with the installation.
    The object is also achieved by an emergency lighting having at least one emergency lighting means and an arrangement according to the invention.
    [0020] Further goals, advantages, features and possible applications of the invention emerge from the following description of an exemplary embodiment on the basis of the accompanying figure. All of the features described can form the subject matter of the invention defined in the appended claims either individually or in an advantageous combination. Show it:
    Fig. 1 shows an arrangement of an operating device and a first light emitting diode, a second light emitting diode and a test switch according to a preferred embodiment of the invention.
    An arrangement according to the invention comprising an operating device 1, a first light emitting diode 12, a second light emitting diode 13 and a test switch 11 according to a preferred embodiment of the invention is shown in FIG.
    The operating device 1 is shown only with elements that are helpful for illustrating the invention. A mains connection 3 of the control gear is used to connect the control gear 1 to a mains voltage supply of a building, for example with AC voltage Uac = 230 V at 50 Hz. The control gear 1 is designed to load one or more lamp modules 2 at a lamp output 5 with a direct voltage Upc to operate. For example, the operating device 1 can provide a direct voltage in a voltage range of 10 to 52 V at one or more lamp outputs 5 with an LED current to be taken according to a voltage-current characteristic.
    The light module 2 comprises light sources, in the example shown light-emitting diodes (LEDs), which are operated with the LED current via the light output 5. The lamp module 2 can include one or more lamps for emergency lighting. In emergency lighting mode, one, several or all of the lighting means of the lighting module 2 can be operated.
    If the elements shown above are typical for general designs of operating devices (ballasts, ballast), the operating device 1 shown has an additional battery connection 7 for use as an operating device in the context of emergency lighting systems. An accumulator 4 is connected to the battery connection 7. The accumulator 4 is electrically charged by the operating device 1 via the battery connection 7 with a charging current. In the case of emergency lighting, for example a failure of the building's mains voltage supply with the mains voltage Uac, the operating device 1 supplies the luminaire connection 5 and thus the luminaire module 2 with electrical energy from the accumulator 4 with a corresponding luminaire current I_ea during a rated operating time which, for example, is 1 h . 2h or 3h can be preset.
    Lamp connection 5, battery connection 7 and a first connection 9.1 and a second connection 9.2 of the operating device 1, which are explained below, are classified as SELV in contrast to the network connection 3 and separated from the network connection 3, carried out inside the operating device by means of a potential barrier from the network connection 3.
    The control of the operating device 1 takes place by means of a control circuit, in particular a microprocessor 6. The microprocessor 6 can not only functions for changing operating states such as standby mode (idle mode), emergency light mode, charging mode of the battery 4, monitoring an LED load at the output , control, but also perform functions for the various tests of the control gear and its connections.
    One or more different function tests can be triggered via an external test switch 11, or specific intervals, for example daily, weekly, yearly for function tests can be determined via the test switch 4. The test switch 4 can be designed, for example, as a rocker switch, as a changeover switch or also preferably as a button.
    According to the invention, the test switch 11 is connected to a first connection 9.1 and a second connection 9.2 of the operating device 1 together with a first light-emitting diode 12, shown as a red light-emitting diode 12, and a second light-emitting diode 13, shown as a green light-emitting diode 13. In particular, the first connection 9.1 is conductively connected to a first contact 12.1 (cathode) of the first light-emitting diode 12 and a second contact 13.2 (anode) of the second light-emitting diode 13. The second connection 9.2 is then conductively connected to a second contact 12.2 (anode) of the first light-emitting diode 12 and a first contact 13.1 (cathode) of the second light-emitting diode 13. The first light-emitting diode 12 and the second light-emitting diode 13 are thus connected in antiparallel to the first connection 9.1 and the second connection 9.2 of the operating device 1. The test switch 11 is connected to the first connection 9.1 and the second connection 9.2 in parallel with the light-emitting diodes 12, 13 connected in parallel to one another.
    The test switch 11 is designed so the first connection 9.1 and the second connection
    9.2 to be conductively connected to each other when the test switch 11 is actuated (short-circuit).
    If the first connection 9.1 and the second connection 9.2 are conductively connected to one another by means of the test switch 11, this short circuit can be detected for the operating device 1, for example, in that a voltage between the first connection 9.1 and the second connection 9.2 collapses, in particular falls below a minimum voltage value, although a limited constant current flows through the first connection 9.1 and the second connection 9.2.
    In a further embodiment of the operating device 1, in particular the constant current source 10 and the microprocessor 6, the short circuit generated by means of the test switch 11 between the first terminal 19.1 and the second terminal 9.2 using a control parameter of the constant current source 10, for example a clocking of a switch the constant current source 10 recognized.
    The recognized short circuit between the first connection 9.1 and the second connection 9.2 can be used in the microprocessor 6 to start a corresponding test procedure. In one embodiment, the duration of the short circuit is also determined and a function test of the operating device 10 is carried out in accordance with the duration of the short circuit, a function test with a predetermined test duration is started, or a function test duration is set. For example, by actuating the test switch 11, the emergency lighting means of the lighting module 2 can be operated by means of energy drawn from the accumulator 4.
    The anti-parallel connection of the light emitting diodes 12 and 13 with respect to the first connection 9.1 and the second connection 9.2 has the effect that depending on the polarity of a voltage between the first connection 9.1 and the second connection 9.2, one of the two light emitting diodes 12, 13 is switched in the reverse direction is, so only one of the two light-emitting diodes 12, 13 can light up. The first light-emitting diode 12 and the second light-emitting diode 13 can thus be specifically addressed individually by the direction of a current that is generated by a constant current source 10 of the operating device 1 and thus each can be specifically stimulated to emit light.
    The constant current source 10 is designed so that the direction of a current impressed between the first connection 9.1 and the second connection 9.2 can be reversed. A reversal of the current direction can be realized in one embodiment of the invention by switching the current direction of the constant current source 10. Either the first light-emitting diode 12 or the second light-emitting diode 13 can thus be excited to emit light by means of the current direction of the current between the first connection 9.1 and the second connection 9.2.
    A status display of the operating device 1 by means of two light-emitting diodes, in one embodiment also light-emitting diodes of different colors, is thus possible.
    With the light-emitting diodes 12, 13 different system states can be displayed, with the constant current source 10, for example, the light-emitting diodes 12, 13 in the states "on", "off", "flashing quickly", "flashing slowly" according to certain operating and test states of the operating device 1, such as "System OK", "Function test running", Duration test running "," Load error "," Battery error "," Charging error "," Emergency operation ".
    According to a further embodiment of the invention, the constant current source 10 can comprise a first constant current source and a second constant current source. The first constant current source is connected in such a way that it generates a first current with a first current direction from the first connection 9.1 to the second connection 9.2 and thus excites the second light-emitting diode 13 to emit light. The second constant current source is connected in such a way that it generates a second current with a second current direction from the second connection 9.2 to the first connection 9.1 and thus excites the first light-emitting diode 12 to emit light. The constant current source 10 can alternatively switch the first constant current source to the first connection 9.1 or the second constant current source to the second connection 9.2. This means that either the first light-emitting diode 12 or the second light-emitting diode 13 can be excited to light up by means of alternative operation of the first constant current source and the second constant current source.
    although only two connections 9.1, 9.2 are present on the operating device 1.
    In a further embodiment of the invention, the first light-emitting diode 12 and the second light-emitting diode are controlled by the constant current source 10 by means of periodic current pulses in the first current direction or in the second current direction via the first connection 9.1 or the second connection 9.2. In a time gate between the current pulses, the microprocessor 6 checks whether the test switch 11 has been actuated and, accordingly, a short circuit has been generated between the first connection 9.1 and the second connection 9.2.
    By means of a current direction at the first connection 9.1 and the second connection 9.2, as well as by detecting a load state, in particular a short circuit between the first connection 9.1 and the second connection 9.2, three functionalities, the operation of two light-emitting diodes for status display and triggering one or more test functions only a pair of connecting terminals integrated. Thus, by means of the arrangement according to the invention, an advantageous reduction in the connection terminals compared to the known operating devices is achieved.
    Particularly preferably, the first light-emitting diode 12, the second light-emitting diode 13 and the test switch 11 are designed to be integrated in a single component, as is indicated in FIG. 1 by means of the broken line. This means that the externally accessible display and operating elements of the emergency lighting system are to be arranged together at a location accessible to a user, the installation effort and the number of assemblies being correspondingly advantageously reduced.
