    description
    USE OF RADIO CONTROL SIGNALS FOR TIME DETERMINATION IN A LIGHTING SYSTEM The present invention relates to a control device and a method for timing one or more components of a lighting system.
    Lighting systems can consist of components such as sensors, control gear for lamps or actuators, switches and dimmers. With the help of operating devices for lamps, such as gas discharge lamps, halogen lamps and in particular light-emitting diodes (LED, OLED), the function of the lamp can be monitored, the lamp can be started and / or dimmed. The lighting and actuators can be controlled using manually operated switches or sensors, e.g. the movements of objects and / or the ambient brightness can be controlled.
    In some applications, the control of the components takes place according to a predetermined time course. For example, the brightness and / or the color tone of a light emitted by a lamp or the position of a roller shutter can be adjusted to the current time of day. To simulate natural sunlight or the course of daylight, a luminaire should typically produce a colder white light in the morning, while warmer white light should be generated in the evening.
    For such controls, knowledge of the current time of day is necessary. In lighting systems with daytime control, a real-time clock (RTC) is often used for this purpose, which is fed by the mains voltage or a battery. However, there is the problem that after a power failure or when the battery is empty, information regarding the current time of day is no longer available. In addition, the clock must be set by the user after installation or a power failure. In order to prevent this, a radio clock that receives a time signal transmitted by radio from a time signal transmitter or a connection to a central control system that transmits the current time of day can be provided. However, the reception of the broadcast time signal is often poor or impossible in shielded buildings and the provision of a connection to a central controller is cost-intensive.
    The invention has for its object to provide a device and a method that reduce the problems described. In particular, the object is to provide a control device, an operating device for illuminants and a method for timing one or more components of a lighting system, with which simple and inexpensive time-dependent control is possible.
    [0006] This object is achieved according to the features of the independent claims. The invention is developed by the features of the dependent claims.
    According to the present invention, a control device for one or more components of a lighting system, a control device for controlling the component of the lighting system according to a predetermined time course, a detection device for detecting a ripple control signal superimposed on a mains voltage and a time base determination device for determining the time base for the course over time by means of the recorded ripple control signal.
    Ripple control signals are used in ripple control technology, as is known, for remote control of power consumers by energy supply companies, for example for switching between high and low tariff current or for switching street lights on and off. According to the present invention, a time base for the predetermined time course can now be synchronized or adjusted on the basis of the ripple control signals sent at certain times of the day, either the transmission time and the start time of the controller or the time offset / relation between the transmission time and the start time being known or .ge1 / 11
    AT15 777U1 2018-05-15 Austrian patent office stores.
    The time base determination device can be designed to determine at least the time period between two successive ripple control signals and to compare the determined time period for determining the time base with at least one predetermined time period. This enables the time base to be determined when ripple control signals are sent at different times of the day, for example for the night / day and day / night switchover.
    Alternatively or additionally, the time base determination device can be designed to decode information contained in the ripple control signal for identification of the ripple control signal and to determine the time base by means of time information associated with the identified ripple control signal.
    [0011] The control device can have a transmission device for transmitting information indicating the time base (system time) to another control device of the lighting system.
    Alternatively or additionally, the control device may have a receiving device for receiving information indicating the time base, the time base determining device being designed to generate a specification for restoring the time base by means of the received information and at least one ripple control signal detected.
    The information indicating the time base can be the current time of day entered by a user or transmitted by another control device or by a timer, the specification for restoring the time base of the time interval between the transmitted time of day and the time determined by the time base determination device the detection of the ripple control signal. With the determined time interval after a power failure, the time base or time of day can be restored or adjusted (inaccuracy of the internal clock) as soon as the ripple control signal is received again.
    [0014] Alternatively or additionally, the control device can have an output device for outputting information indicating the time base to a display device for manual correction of the time base.
    The time base can be the current time and the control device can have a clock, the control device being designed to set the clock by means of the determined current time of day or to adjust the time signal emitted by the clock.
    At least one component can be an operating device for lamps with a controllable color tone, the control device being designed to control the color tone and, if appropriate, the brightness in accordance with the predefined time profile.
    [0017] According to the present invention, an operating device for light sources has one of the control devices described above.
    According to the present invention, the method for controlling one or more components of a lighting system in accordance with a predetermined time profile comprises the steps: detecting a ripple control signal superimposed on a mains voltage and determining a time base for the time profile by means of the detected ripple control signal.
    The time period determined between two successive ripple control signals can be compared for determining the time base with at least one predetermined time period and / or information contained in the ripple control signal can be decoded for identification of the ripple control signal and the time base can be determined by means of time information associated with the identified ripple control signal.
    Alternatively or additionally, information indicating the time base can be transmitted to an external control device of the lighting system.

    Patent Office As an alternative or in addition, information indicating the time base can be received and a specification for restoring the time base can be generated by means of the received information and at least one recorded ripple control signal.
    Alternatively or additionally, information indicating the time base can be output to a display device for manual correction of the time base.
    The time base can be the current time of day and a clock can be set by means of the determined current time of day or the time signal emitted by the clock can be adjusted.
    The invention is explained in more detail with reference to the accompanying drawings. Show it:
    1 shows an exemplary embodiment of a control device according to the present invention, [0026] FIG. 2 shows a first diagram with a timing control course on a day and a second diagram with a ripple control signal received on the day according to the present invention, [0027] 3 shows two diagrams with ripple control signals occurring at different times, and [0028] FIG. 4 shows an exemplary embodiment of an operating device according to the present invention.
    Components with the same functions are identified in the figures with the same reference symbols.
    According to the present invention, ripple control signals are used to obtain the current time required for a time control of a lighting system, the transmission time and / or transmission day are known. Ripple control signals can be used to transmit control commands in a power network, with pulse sequences in the frequency range from 110 Hz to about 2000 Hz of the network voltage having an amplitude of approximately 1 to 4% of the respective nominal voltage being superimposed.
    Fig. 1 shows a simplified schematic representation of a control device 1 for an operating device 2 according to the present invention. The operating device 2 is used to operate a lamp (not shown) and is controlled by the control device 1 in accordance with a predetermined control process in which the lamp is to generate certain brightness levels and color temperatures by dimming by the operating device 2, for example at certain times of the day.
    [0032] The illuminant can comprise a light emitting diode (LED) or several LEDs. The LEDs can be inorganic or organic LEDs. The multiple LEDs can be connected in series or in parallel. The plurality of LEDs can also be connected in more complex arrangements, for example in a plurality of series circuits connected in parallel with one another, and / or have different color tones, in particular for generating warm and cold white light.
    The control device 1 can be connected via the connections L1 and N to a power supply system of a power supply company which modulates ripple control signals onto the mains voltage that can be tapped at the connections L1 and N. In this example, the line voltage present at the connections L1 and N also serves to supply the control device 1. The control device 1 has a detection device 3 connected to the connections L1 and N for detecting the ripple control signals superimposed on the line voltage, and a control device 4 for controlling the operating device 2 , a determination device 5 for determining and transmitting the time base to the control device 4 and a storage device 6 for storing information by means of which the time base can be determined from the reception times of the ripple control signals.
    The storage device 6 is a permanently installed or removable non-volatile

    AT15 777U1 2018-05-15 Austrian patent office
    Data storage. The time base transmitted from the determining device 5 to the control device 4 can be a start pulse for starting the above-mentioned control process, the current time of day or system time.
    The control device 4 starts or synchronizes the control process according to the received start pulse or takes over the transmitted time of day and starts the control process according to a predetermined start / time of day.
    The upper diagram in FIG. 2 shows a time course of the dimming level and / or a color temperature that is controlled by the control device 4 and that repeats itself every day. According to the course shown, the color temperature change or dimming process should start at 6:00 a.m., whereby the color temperature or the dimming level changes continuously until 7:30 a.m. and between 10:30 a.m. and 12:30 p.m. further to a final value before it changes from 4:30 p.m. to 7:00 p.m. changes continuously in the opposite direction.
    In the lower diagram in FIG. 2, the time profile or the transmission time of a ripple control signal R sent by a power supply company every day is shown. As shown in FIG. 2, a ripple control signal R is sent at 3:30 a.m. and detected by the detection device 3. There is a time difference At of two hours and thirty minutes between the broadcast time of 3:30 a.m. and the start of the dimming process at 6:00 a.m. This time difference At is stored in the memory device 6.
    If the ripple control signal R is detected by the detection device 3 and the reception is communicated to the determination device 5, the determination device 5 transmits the time difference At stored in the storage device 6 to the control device 4. The control device 4 starts a timer and after the time At 2, which is also controlled by means of the time information displayed by the timer. In this way it is not necessary to provide a clock for permanent measurement of the current time of day. The reception of the ripple control signal R only triggers the specified / programmed control process at the correct time.
    However, it is also possible to store the transmission time assigned to the ripple control signal R in the memory device 6 and to transmit this time to the control device 4 when the ripple control signal R is detected, so that one provided for measuring the current time of day in the control device 4 Clock is set / adjusted. The control device 4 then starts the dimming process shown in FIG. 2 in accordance with the current time of day indicated by the clock.
    3 shows a diagram A with ripple control signals R1 and R2 transmitted on the days from March to September (summer tariff) and a diagram B with ripple control signals R3 and R4 sent on the days from October to February (winter tariff). The ripple control signals R1 and R3 sent at 7:00 a.m. and 6:00 a.m. indicate the start of a high tariff and the ripple control signals R2 and R4 sent at 6:00 p.m. and 10:00 p.m. indicate the start of a low tariff.
    In order to identify the individual ripple control signals R1..R4 for obtaining the current time without decoding the signals, the time differences At NS , At H s, At NW , At H s with the associated transmission times ( 7:00 a.m. and 6:00 p.m. or 6:00 a.m. and 10:00 p.m.). The determination device 5 measures the time spans / time differences (time intervals) between two ripple control signals R1..R4 detected by the detection device 3 and compares the measured time difference with the stored time differences At NS (13 hours), At H s (9 hours), At N w (16 hours), At H s (8 hours) to identify the ripple control signals R1..R4 or to determine the current time. The current time can thus be determined at the time of the second ripple control signal detected.
    An identification of the period March to September and the period October to February is also possible by means of the measured time differences At NS , At HS , At NW , At HS , and could be taken into account in a control if necessary. For the identification of an er4 / 11
    AT15 777U1 2018-05-15 Austrian
    Time spans / time differences between more than two successive ripple control signals can also be determined or stored by the patent office. In addition, the length of time of the ripple control signals can be used for identification.
    If the ripple control signals contain information which (possibly in conjunction with the time difference determination described above) permits unambiguous identification of the ripple control signals (i.e. the morning or evening signal), this information can be obtained with the respective (known) transmission times of the ripple control signals and / or other information can be stored in the storage device 6.
    The detection device 3 then outputs the detected ripple control signals R1..R4 to the determination device 5, which decodes the information contained in the ripple control signals R1..R4 and compares the decoded information with the information stored in the memory device 6 by the current one To determine the time of day.
    If ripple control signals R1..R4 occur which are not sent at certain / predefined times, these could be noted in the memory device 6, identified after the detection and sorted out, or not used for determining the time base.
    The information for identifying and determining the time of the ripple control signals R1..R4 can be stored in the memory device 6 by the manufacturer of the control device 1 or the user. Alternatively or additionally, the determination device 5 can be designed to determine and store the information for identifying and determining the time of the ripple control signals R1..R4 and / or to update the stored information.
    For this purpose, the determining device 5 identifies ripple control signals R1..R4, stores information for identification and acquisition / transmission time and determines ripple control signals R1..R4 from the continuously stored information, which are repeatedly (periodically) sent at certain times. These ripple control signals R1..R4 are used for a correction of the internal clock (not shown) of the control device 1 and / or for the automatic setting of the clock after a power failure (restoration of the time base).
    The corrected or restored time can also be transmitted to other control devices of a lighting system that do not themselves have a device for recognizing the ripple control signals. For this purpose, the control device 1 has a transmission device for transmitting information indicating the time base (time) to another control device.
    [0049] The control device 1 can also have a receiving device for receiving information indicating the time base from the other control device or a user input device. The time currently measured by the clock of the control device 1 could be output to a display for manual correction by the user by means of an output device.
    The determination device 5 and / or storage device 6 shown in FIG. 1 can be integrated into the control device 4. The control device 1 can be a component of the operating device 2.
    Fig. 4 shows a further embodiment of an operating device 2 according to the present invention, which can operate differently colored light-emitting diodes in such a way that the brightness and the hue of the emitted light are adapted to the brightness and the hue of natural sunlight or the course of daylight can.
    The operating device 2 has the detection device 3, the control device 4, an LED converter 7 with a plurality of channels or output connections 8 and a timer circuit 9 which contains the determination device 5 and the storage device 6.
    Cold white light generating LEDs can be operated on one of the channels and warm white light generating LEDs can be operated on another channel.

    Patent Office The detection device 3 additionally contains a line voltage monitoring circuit (not shown) which monitors the line voltage level at the connections 11 and N for the operating device 2 and reports a failure or a certain deviation / fault in the input voltage to the control device 4, so that the control device 4 can end the current, daylight-compliant lighting control and activate emergency lighting by means of an energy store (not shown).
    In normal operation with the correct mains voltage, the detection device 3 detects the ripple control signals R1..R4 modulated on the mains voltage and reports them to the timer circuit 9, which determines the position in time of the ripple control signals R1..R4 and a signal indicating the time base to the control device 4 transmits as described above. The control device 4 controls the LED converter 7 according to a programmed sequence, which specifies a specific color temperature of the generated white light and a specific brightness for specific times of the day, the time of day being determined on the basis of the signal transmitted by the timer circuit 9.
