    Description: The present invention relates to a control unit for a luminaire unit of a lighting system, the control unit comprising a data processing unit, in particular a non-volatile memory for storing a luminaire identifier and at least one output for at least one illuminant or at least one illuminant source and at least one input for receiving Control codes comprises, wherein the control unit controls the at least one illuminant and / or the at least one illuminant source, in particular switches on and off after receipt of control codes, the luminaire unit having continuous operating power consumption with the at least one switched-on illuminant in continuous operation.
    Lighting systems such as emergency lighting systems are used, among other things, in large construction projects. There is a need to be able to monitor and control such a system as simply and centrally as possible and, if necessary, to recognize and locate faulty lights or other components or to influence system settings. Thanks to the central control and monitoring, the maintenance effort can be kept low and the lighting system can thus be operated cost-effectively.
    There is a need for central monitoring, in particular in the case of emergency power lighting systems, to ensure that the lamps are functional at all times. Due to the fact that the illuminants are normally switched off, the inoperability cannot be noticed by a person deliberately noticing a defective illuminant. Depending on the size of the system, personal monitoring of each individual lighting unit is generally not possible for such systems. Emergency lighting systems usually have their own supply network that is independent of the normal house network.
    Various systems and methods are known which provide the monitoring and control of an emergency power lighting system.
    An emergency power lighting system is known from DE 19 832 550 A1, in which a control unit called a data processing unit is connected between the lamps and the connections of these lamps, which control unit can control the lamps and has a memory. The control units are programmable via the applied supply voltage and each control unit or the corresponding illuminants can be assigned a luminaire identifier, which is stored in the memory. To monitor the functionality of the emergency power lighting system (mode 7), the control units are programmed in such a way that they switch on the respective lamps at the same time as all other control units at the start of the monitoring routine and switch them off again after a time assigned to the light identification, which is not the same for any two control units , In this case, the current or the power consumption is measured over the entire emergency power lighting system, so that the occurrence of a drop in power at the time when a lamp is switched off can be used to determine whether the lamp is functional.
    Disadvantageously, this method or such an emergency lighting system only works without measurement errors if the drop in output when a lamp is switched off is large enough to be reliably detected. Since more and more light sources with very low nominal powers, such as LEDs or OLEDs, are being used, the power drop in such systems can be small and, especially in large emergency power lighting systems, can no longer be reliably detected due to long cable runs.
    The invention is therefore based on the object to provide means and / or methods that ensure the detectability of a load drop resulting from switching off a lamp or a lamp unit, ie the unit consisting of lamp and control unit, even with lamps with low power consumption ,
    This object is achieved in a control unit with the features of the preamble of claim 1 in that by means of the control unit the actual power consumption of the lamp unit can be raised after receiving at least one predetermined control code via the continuous operating power consumption.
    Thus, an increased power drop can be generated, which is reliably detectable, while the advantages of low power consumption continue to exist in continuous operation, in particular the low energy consumption of the entire lighting system. An increase in the actual power consumption over the continuous operating power consumption only has to exist for a very short period of time, so that components do not have to be designed for continuous operation with an increased actual power consumption.
    The invention provides various options for how the actual power consumption can be increased. For example, the control unit can control a lamp source, which in turn changes the supply of the lamps in such a way that the power consumption of the lamps increases. This illuminant source can be, for example, a current source of the lamp unit, the control unit being able to raise the current output by the current source and thus flowing through the illuminant, so that the power consumption of the illuminant increases. Since such a light source is necessary to supply the light in any case, no additional component has to be advantageously provided. It is both in the sense of the invention if the illuminant source is arranged within the control unit and influences the outputs of the control unit, and also that the illuminant source is arranged outside the control unit, in particular between the control unit and the illuminant.
    CH 715 090 A2 [0011] It is also possible for the control unit or the illuminant to have at least one load resistor to increase the ACTUAL power consumption, which is assigned to the light unit. The load resistance can be connected in series with the illuminant, for example, the control unit then controlling the switches with which the load resistance can be switched on. In this way, advantageously no lamp is exposed to a power consumption that is higher than the nominal power consumption, so that the lamps are not overused. Alternatively, the load resistor can also be connected in parallel with the lamp.
    Instead of a load resistor, the lamp unit can also have a plurality of redundant lamps, which can be switched on and off by the control unit to change the actual power consumption. At least one lamp is switched on during normal operation of the lighting system and at least one lamp is only switched on for the test routine. When using LEDs, for example, the assignment of which illuminant is switched on in continuous operation and which illuminant is used to briefly increase the power consumption during a test routine can then advantageously be exchanged as soon as aging effects are determined to a certain extent to that previously determined for continuous operation Illuminants can be seen. Such aging effects in LEDs are, for example, the reduction in the color temperature or the brightness of the emitted light. Above certain limit values, old LEDs are no longer suitable for the normal operation of the lighting system. However, the aged LEDs are still suitable for changing the actual power consumption, since the power consumption does not change due to the aging effects. A change of all LEDs is advantageously only necessary when all LEDs have successively reached their aging limit, so that the maintenance effort is reduced. To monitor the signs of aging, a sensor can be provided on the lamp unit, for example, which measures the brightness and / or color temperature of the respectively switched on lamp.
    [0013] In a preferred embodiment, the control unit can be controlled and / or programmed via the supply voltage applied to the control unit. The applied voltage can be modulated for the transmission of control codes or the voltage applied to the supply network can be switched on and off at certain time intervals. In this way, the supply network which is required to operate the lighting units can advantageously also be used to control the control unit, and no further components have to be provided for this purpose.
    Alternatively, it is also conceivable that the input for receiving control codes is a receiver for radio signals, a radio transmitter also being provided in the lighting system. The radio transmitter can be arranged on a central unit of the lighting system, for example, while each control unit has its own, in particular identifiable, radio signal receiver. It is then advantageous to transmit the control codes independently of the supply network. In this way, a system could be created from self-sufficient individual luminaire units, each of which is connected to an already existing supply network and in which it is then possible to dispense with a separate supply network for the lighting system. Such an embodiment comes into question if it is not an emergency power lighting system or if there is no need for a separate, self-sufficient supply network for the lighting system.
    In one embodiment variant of the invention, the lighting system has a central unit from which the control of the lighting system is based. For this purpose, the central unit is connected to each lamp unit, in particular via a supply network or radio connections. The central unit has measuring devices for measuring the power consumption of the lighting system and / or possibly means for switching or modulating the supply voltage for controlling the control unit. Insofar as the central unit is connected to the lighting units via a supply network, it is also connected to a voltage source, such as an emergency power generator or a battery unit, which provides the voltage to be applied to the supply network. The central unit can therefore combine all functions that only need to be present once in the system.
    [0016] The control unit according to the invention can be part of an emergency power lighting system. Since the illuminants do not normally light up in such a case and a defective illuminant cannot therefore be easily discovered, but their functionality is particularly important, regular function tests are essential. As a result, the advantages of a centrally controllable and testable system described above are particularly effective.
    In a particularly preferred embodiment, at least one program with at least one program routine is stored in the control unit, a program routine increasing the actual power consumption of the lamp unit and switching off the lamp unit after a time which is dependent in particular on the lamp identification. Due to the very low latency times in a digital program memory, the test time and thus the time in which any overdriving of individual components takes place can be kept low. Further programs can also be stored in the program memory, for example for the automatic assignment of the luminaire identification when setting up the lighting system.
    A functional test of a lighting system with a control unit according to the invention can be carried out using the following method:
    According to a routine schedule or upon a manually entered command, the routine is started in the central unit. The central unit then transmits an execution command by means of a control code to the control units of each lamp unit. This can be done via the supply network, insofar as the lighting units use one
    CH 715 090 A2 are connected to the central unit. It is conceivable, for example, that the central unit transmits a control code by means of voltage modulation or by switching the supply voltage on and off, so that, as far as the central unit is connected to the supply network via switching means, the control code consists of a sequence of switching operations of these switching means. It is also conceivable for the control code to be transmitted by radio signal, in so far as transmission and reception devices are provided on the central unit and each control unit.
    After receiving the control codes, one or each control unit according to the invention raises the actual power consumption of the lamp units and switches on the respective lamp. Thereafter, the control units switch off the illuminant again after a predetermined time, which is dependent on the lamp identification stored in them. The predetermined time is not the same for any two lamp units of the lighting system. The luminaire identification of each luminaire unit is also stored in the central unit and possibly linked to further information on the respective luminaire unit, such as the installation location in the building. The time period assigned to the respective lamp identification until the lamp is switched off is also stored in the central unit. If necessary, the data stored in the central unit can be synchronized with the data stored in the control units before the start of the routine.
    [0021] The individual time periods until a light source is switched off are dimensioned such that sufficient time passes between two switch-offs, so that the measurement of the load drop can be assigned to a light unit without any doubt. The power consumption of the entire system is measured in the central unit during the entire process. After the last luminaire unit has been switched off, the function test is ended and the power consumption of the luminaire units is put back into the continuous operating state by the respective control units. If necessary, a protocol is finally generated and saved in the central unit.
    If the central unit does not detect a load drop at a time at which a switch-off process of a lamp unit is stored in the data stored in it and thus a load drop is expected at this point in time, a message is generated that this lamp unit has a defect seems or has.
    The invention is explained in more detail below with reference to figures in which preferred exemplary embodiments of the invention are shown.
    [0024] The figures show:
    Fig. 1: A lighting system in a first embodiment with lighting units according to the invention with control units according to the invention in a schematic representation, the lighting units being controlled via the supply voltage of the lighting network;
    2 shows a schematic illustration of a lighting system in a second embodiment with luminaire units according to the invention with control units according to the invention, the luminaire units or the control units being controlled by radio;
    3: a lighting unit in a first embodiment with a control unit according to the invention in a schematic representation;
    Fig. 4: a lamp unit in a second embodiment with a control unit according to the invention in a schematic representation.
    1 shows a lighting system 1 with a central unit 2 connected to a voltage source 7, to which a supply network 3 is connected. Several lighting units 4 are arranged on the supply network 3, each of which has a control unit 5 and a lamp 6, e.g. have in the form of LEDs. A central control unit 10 is arranged within the central unit 2, which comprises several functions: it serves, among other things, as a control unit for the control units 5. For this purpose, program routines and information about the individual control units 5 are stored in the central control unit, such as the lamp identification of the control units 5 When a program routine is called up, control codes are transmitted to all or specifically addressed control units 5. In the central control unit 10 there is also a write memory for the data recorded on the measuring devices Ila, lib for power consumption in the lighting system 1. The measuring devices Ila, lib are in each case a voltage measuring device Ila and a current measuring device 11b, from the two measurement results of which the power consumption of all the lighting units 4 in the lighting system 1 can be calculated, or is calculated by the central control unit 10. The central control unit 10 further comprises an interface for entering control commands and outputting messages. Control codes are transmitted from the central unit 2 to the control units 5 via the supply network 3, e.g. via voltage modulation.
    Fig. 2 shows a further embodiment of a lighting system 1 according to Fig. 1, wherein the control codes are not transmitted via the supply network 3, but a radio transmitter 14 is arranged for the transmission of control codes in the central unit 2 and on the control units 5 in each case a radio receiver 15 is arranged.
    In Fig. 3, a lamp unit 4 is shown, compared to the embodiment shown in Fig. 1, another lamp 6a as a means for increasing the power consumption of the lamp unit 4 on the control unit 5th
    CH 715 090 A2 is arranged. Each lamp 6, 6a can be switched individually or both lamps 6, 6a can be connected in series with one another. For this purpose, each of the two illuminants 6, 6a can be bridged by means of the switches 23, 23a, the switches 23, 23a being controlled by the switching unit 20, which in turn is controlled by the control unit 5. The control unit 5 has a power supply unit 17 and a memory 18, which serve to supply energy to all components of the control unit 5 on the one hand and the lamps 6, 6a on the other. The storage capacity of the memory 18 is designed to supply the control unit 5 with energy for a certain period of time even when the supply voltage is not present via the supply network 3.
    In the control unit 5, a data processing unit 19 is also arranged, from which all control commands of the control unit originate and affect the power supply 17 and or the switching unit 20. The data processing unit 19 has an in particular non-volatile data memory for storing program codes, which can be programmed or addressed by the central unit 2 or by the central control unit 10. For this purpose, the data processing unit 19 processes control codes which the control unit 5 receives via the input 21a, 21b and thereupon directly controls the outputs 22a, 22b via the power supply unit or the output 22c in the course of the execution of the stored program routines and thus the switching unit 20, which in turn controls the Control switches 23, 23a.
    In the embodiment shown in FIG. 4, the control unit 5 is not connected to the supply network 3, but to its own voltage source 25. In addition, the control unit 5 has the signal input 21c, to which the radio receiver 15 is connected for receiving control codes. It is also conceivable that the control unit 5 or the data processing unit 19 uses the input 21c as an output and the radio receiver 15 also has a transmission function so that the control unit can transmit information back to the central unit 2 or the central control unit 10. For example, before the execution of a program routine, the information stored in the control units 5 of each light unit 4 can be synchronized with the information stored in the central control unit 10, in particular the light identifiers.
    To change the power consumption of the lamp unit 4, the control unit 5 controls the power supply 17 so that the only lamp 6 is operated with different currents. The power supply 17 can therefore generate different currents.
