Definitions

  • the invention relates to a dimmer, namely a device for controlling the electrical power consumption of an electrical load, in particular an integrated or connectable lighting device. Dimmers are well known and are used to vary electrical output.
  • phase control Such a power variation can preferably be carried out by phase control or phase control.
  • phase control the current is switched on with a delay after the alternating voltage crosses zero and flows until the next current zero crossing. It is preferred for inductive load behavior. With phase control, however, the current is switched on immediately after the zero crossing and switched off again before the next zero crossing. This is preferred for capacitive load behavior.
  • the dimmer In order to generate the necessary control commands to its switching components, the dimmer has a main control device.
  • the invention relates more specifically to so-called multi-channel dimmers. These have several individual dimmers, each of which controls part of the electrical load. To increase performance, these so-called dimmer channels can be switched on the output side in parallel, sequentially or mixed. Several physical channels are connected together to create a powerful logical channel. The dimmer channels can be in one device or in several devices.
  • German patent specification DE102006013518B3 discloses a multi-channel dimmer with a plurality of dimmer units, the multi-channel dimmer automatically checking whether load outputs have been connected in parallel, and in the context of this test mode, a dimmer unit takes on the role of a master dimmer and the other dimmer units take on the role of a slave dimmer.
  • the citation EP 2 925 095 A1 discloses a lighting controller comprising a power input for receiving alternating current, a master processor and one or more slave processors. Each slave processor is configured to use appropriate switching components to manipulate half-waves of alternating current to output a phase-cut alternating current.
  • the citation US 2004/0212325A1 discloses a load control system consisting of at least two triac devices connected in parallel to a load for supplying power to the load, at least one driver circuit connected to the at least two triac devices, and a controller connected to the at least one driver circuit is connected, wherein the controller controls the at least one driver circuit so that the at least two triac devices are actuated substantially at the same time.
  • EP 1 158 841 A2 a dimmer for brightness adjustment with an adjusting device for adjusting a dimming phase angle and with a control device for controlling a circuit breaker depending on a dimming phase angle set by the adjusting device.
  • each dimmer channel has its own channel control device, advantageously a simple processor, as well as a measuring device for measuring the electricity in the channel, which can also be partially formed by this processor. Thanks to the measuring device, the channel control device receives the information about the periodic behavior of the electricity in the channel necessary for detecting the phase angle or phase edge.
  • the control commands generated by the main control device are transmitted via a communication connection to the channel control devices of the dimmer channels and implemented on site in accordance with the information about the periodic behavior of the electricity in the channel.
  • the complexity of the measuring devices leads to high development costs and production costs. Inaccuracies in zero crossing detection can also arise due to component tolerances or aging of the components. The resulting time differences then lead to non-synchronous switching of the dimmer channels and to the problems described above. It is possible to replace the device or recalibrate its components, but not without costs and possibly consequential damage due to operational disruption.
  • the patent applicant has shown in a previous patent application how to solve many such problems. In short, this is achieved by the main controller also distributing synchronization signals to the channel controllers. These synchronization signals are based on information from the measuring device in a single dimmer channel, therefore called the measuring dimmer channel here. However, it has now been shown that an alternative path with optimization potential exists.
  • the dimmer according to the invention comprises at least a first measuring dimmer channel and two further dimmer channels (second and third dimmer channel), each with a channel control device.
  • the measuring dimmer channel includes a measuring device for measuring the electricity in the channel. Your information about the behavior of the electricity in the measuring dimmer channel is advantageously transmitted to the channel control device of the measuring dimmer channel.
  • the dimmer advantageously further comprises a main control device which can generate at least control commands for the dimmer channels, as well as a main communication connection which is at least suitable for transmitting such control commands from the main control device to the channel control device of a dimmer channel.
  • the dimmer further comprises at least one channel communication connection from the (first) measuring dimmer channel to the second dimmer channel, preferably with an element for electrically isolating the first dimmer channel from the second dimmer channel, preferably with an opto-coupler or alternatively with a transformer circuit.
  • This channel communication connection can transmit information, at least about the behavior, preferably the periodic behavior, of the electricity in the measuring dimmer channel, from the measuring device or from the channel control device of the first dimmer channel to the second dimmer channel, advantageously to the channel control device of the second dimmer channel.
  • the respective channel communication connection is preferably also suitable for transmitting information in the opposite direction.
  • channel communication connections between the channel control devices can be established with little additional effort, which even partially the communication connections between the channel control devices and the main control device of the dimmer.
  • the information about the periodic behavior of the electricity in a measuring dimmer channel is advantageously an indication of the time of at least one zero crossing of the voltage in the measuring dimmer channel.
  • the channel control device of the second dimmer channel can generate information about the periodic behavior of the electricity on site based on the information about the periodic behavior of the electricity in the measuring dimmer channel, with which it can switch the electricity in the channel precisely and synchronously with the other dimmer channels.
  • This stored data preferably contains a time value which is an estimate of the time for processing and transmitting the information from the measuring dimmer channel to the control device of the second dimmer channel.
  • the time value is a constant for each dimmer channel and may contain values about the time for the generation of the information by the measuring device, its transmission through the channel communication connection or through the channel communication connections from the measurement dimmer channel to the second dimmer channel and its processing in the dimmer channels. It can be determined for each dimmer channel, namely from a calibration with measurements on the dimmer or other dimmers from the same series or in a simulation using a computer.
  • the data has preferably been permanently stored in the channel control devices.
  • the information about the periodic behavior of the electricity in the measuring dimmer channel arrives at the channel control device of the second dimmer channel with a short delay, but especially with repetition and despite aging of the components with almost the same delay . It is noteworthy that this even applies to the total transmission delay when the signal is sent from the original channel control device of the measurement dimmer channel via some channel control devices and over the channel communication links therebetween. Accordingly, the first dimmer channel for a channel communication connection can be other than the measurement dimmer channel.
  • the channel communication connection can at least also transmit control commands from the main control device from the channel control device of the first dimmer channel (measuring dimmer channel) to the channel control device of the second dimmer channel.
  • control commands from the main control device from the channel control device of the first dimmer channel (measuring dimmer channel) to the channel control device of the second dimmer channel.
  • the measuring dimmer channel there are the two channel communication connections between the channel control devices of the measuring dimmer channel (first dimmer channel) and the second dimmer channel and between the channel control devices of the second and third dimmer channels.
  • the measuring dimmer channel therefore has a direct channel communication connection with several control devices of other dimmer channels. This may be implemented as as many individual channel communication connections, or as a single channel communication connection for bus communication or the like, according to which telegrams are received at the destination thanks to an individual address or a group address.
  • the main control device is a channel control device.
  • the Figure 1 shows the functional breakdown of a multi-channel dimmer D on the supply network N, L1.
  • the multi-channel dimmer D has several galvanically isolated dimmer channels K1, K2, Kx, each with a channel control device S1, S2, Sx.
  • the dimmer channels are connected in parallel to the load L on the output side via connection terminals A1, A2, Ax so that each can supply part of the current to it.
  • the dimmer D starts based on an external command B.
  • a main control device H generates control commands, which reach the channel control device S1 of the dimmer channel K1 via a communication connection V.
  • the dimmer channel K1 contains a measuring device M1 which is suitable for generating information about the behavior of the electricity at a point in the channel, namely information about the zero crossing of the voltage.
  • the dimmer channel K1 is therefore also called the measuring dimmer channel.
  • a communication connection transmits such information from the measuring device M1 to the channel control device S1.
  • a channel communication connection V12, V23, V(x-1)x leads from one dimmer channel to the next dimmer channel.
  • These channel communication connections V12, V23, V(x-1)x are preferably suitable for transmitting information about the behavior of the electricity in the measuring dimmer channel K1 to the channel control device S2, Sx of the next dimmer channel K2, Kx, here from the channel control device S1, S2 of one dimmer channel K1, K2 to the channel control device S2, Sx of the other dimmer channel K2, Kx.
  • these channel communication connections V12, V23, V(x-1)x also carry on the control commands from the main control device H.
  • the communication connections V, V12, V23, V(x-1)x between the galvanically isolated main control device H and the dimmer channels K1, K2, Kx each contain an optocoupler on both sides.
  • the channel communication connections V12, V23, V(x-1)x between the dimmer channels K1, K2, Kx link the measuring device M with the respective channel control devices S1, S2, Sx for very real-time transmission.
  • the channel communication connections V12, V23, V(x-1)x are designed to be unidirectional, which is why separate communication connections V deliver the control commands from the main control device H to each dimmer channel K1, K2, Kx and return any feedback.
  • the Figure 3 shows measuring dimmer channel K1, dimmer channel K2 and their channel communication connection V12 of the second multi-channel dimmer according to the invention, the circuits of the measuring device M, the channel communication connection V12 and the dimmer channel K2 being shown in simplified form.
  • An operational amplifier N11 of the measuring device M1 converts the mains voltage of 230 volts into a signal that is easier to process.
  • a comparator N12 of the measuring device M1 analyzes this signal for zero crossings. The zero crossings are passed on directly to the channel control device S1 but also to an optocoupler in the channel communication connection V12.
  • the optocoupler For galvanic isolation, the optocoupler contains a light-emitting diode and a light-sensitive resistor, which switches a current via the resistor R in the dimmer channel K2. Thus, the optocoupler transmits the information about the zero crossings with little delay to the channel controller S2 and to the next channel communication link.
  • control commands are sent to the main control device H in a similar way as in the variant of Figure 1 via a single communication connection V to the channel control device S1 of the dimmer channel K1.
  • the channel control device S1 passes it on to the next dimmer channel K2 via the channel communication connections V12, as in the variant Figure 2 .
  • Figure 3 sketched channel communication connections V12, V23, V(x-1)x, for example supplemented in front of the light-emitting diode with a switch and a resistor in a series with earth.
  • the switch for example a transistor, is switched between conducting and blocking by an output of the respective channel control device Sx.
  • the switch When the respective comparator Nx2 energizes the light-emitting diode, the switch can impose small voltage steps on the signal, which lead to small intensity steps in the light from the light-emitting diode.
  • a simple voltmeter can detect the corresponding resistance steps in the light-sensitive resistor on the receiver side. However, they do not trigger a zero crossing detection there. These steps thus encode the control commands of the main control device H and are passed on to the respective channel control device Sx+1 by the voltmeter.
