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 anschliess- ble lighting device. Dimmers are well known and they serve to vary electrical power.
- phase control the current is delayed after the zero crossing of the alternating voltage is switched on and flows until the next current zero crossing. It is preferred for an inductive load behavior.
- phase-section control the current is immediately switched on after the zero crossing and is switched off again before the next zero crossing. This is preferred in a kapaziti ⁇ ven load behavior.
- the dimmer has a main control device. More specifically, the invention relates to so-called multi-channel dimmers. These have several individual dimmers, which each control a portion of the electrical load.
- these so-called dimmer channels can be switched on the output side in parallel, sequential or mixed mode. It always connects multiple physical channels and ent ⁇ is a powerful logical channel.
- the dimmer channels can be in one device, or in several devices. However, it is important, precisely because of this interconnection, that the outputs of the dimmer channels are largely synchronized. For example, if two channels were connected in parallel and the second channel was too late (with phase control) or switches too early (at phase section), the first channel is more overloaded than if both synchronously false scarf ⁇ th. This can lead to excessive heating or failure of the first dimmer channel, or even to turn off the dimmer.
- each dimmer channel has its own channel control device, with advantage a simple processor, as well as a measuring device for measuring the electricity in the channel, which may also be partially formed by the ⁇ sen processor. Thanks to the measuring device, the channel controller receives the necessary for the detection of the phase angle or the phase section Informati ⁇ tions about the periodic behavior of the electricity in the Ka nal.
- the control commands generated by the main controller are transmitted via a respective communication link to the channel controllers 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.
- component tolerances or aging of the components can cause inaccuracies in the zero crossing detection.
- the resulting temporal differences then lead to a 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, if necessary, consequential damage due to malfunction.
- the Applicant has shown in an earlier patent application how to solve many such problems. This is, in short, achieved by the fact that the main control device also distributes synchronization signals to the Kanal horreinrich ⁇ lines. These synchronization signals are based on the information from the measuring device in a single dimmer channel, here called the measuring dimming channel. It has however, it has now been shown that an alternative path with potential for optimization exists.
- the present invention includes dimmer Minim ⁇ least two dimmer channels each having a channel controller. At least one of the dimmer channels is a dimming channel because it includes a measuring device for measuring the electricity in the channel. Your information on the behavior of electricity in the measurement dimmer channel are transmitted to Kanal horrein ⁇ direction of the measuring dimmer channel.
- the dimmer further comprises a main control device which can generate at least control commands for the dimmer channels, and a Hauptkommu ⁇ nikationstress which is at least suitable for transmitting such control commands from the main controller to the channel control device of a dimmer channel.
- the dimmer comprises at least one channel communication connection from a first dimmer channel to a 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 via the behavior, preferably the periodic behavior, of the electricity in the measuring dimmer channel, from the measuring device or else from the channel control device of a first dimmer channel to a second dimmer channel, preferably to the channel control device of the second dimmer channel.
- the Kanalkom ⁇ munikationsitati is also adapted to transmit information in the reverse direction.
- the information about the periodic behavior of the electricity in a measuring dimmer channel is preferably an indication of the time of sending the information through the Ka ⁇ nal horrinibial horrinum cortex, or preferably an indication of the time of at least one zero crossing of the voltage in the measuring dimmer channel.
- the channel controller of the second dimmer channel Based on stored data, the channel controller of the second dimmer channel based on the information about the periodic behavior of electricity in the dimming channel information about the perio ⁇ dische behavior of the electricity suburb generate, with which they can switch the electricity in the channel exactly and synchronously to the other dimmer channels ,
- This stored data preferably contains a time value which equals an estimate of the time for the processing and the transmission of the information from the measuring dimmer channel to the control device of the second dimmer channel.
- the time value is a constant for each dimple channel and may include values over time for the information to be generated by the meter, transmitted through the channel communication link or through the channel communication links from the meter dimmer channel to the second dimmer channel and processed 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 by means of a computer. Preferably, the data has been permanently stored in the channel control devices.
- the information comes concerning the periodic behavior of the electricity in the measuring signal channel with a low but above all repetition and despite aging of the components with almost the same delay at the channel control device of the second dimmer channel. It is noteworthy that this applies even to the overall transmission delay when the signal is transmitted from the original channel controller of the measurement dimmer channel via some channel controllers and through the channel communication links between them. Accordingly, the first dimmer channel to a channel communication link may be other than the measurement dimmer channel.
- the channel communication link may at least also transmit control commands from the main controller from the channel controller of the first dimmer channel to the channel controller of the second dimmer channel.
- the instructions for switching behavior are distributed to several dimmer channels, which eliminates direct communication links to the main controller of the dimmer. Again, this may be unidirectional for cost reasons, although bidirectional communication brings benefits.
- the measurement dimmer channel has a direct channel communication link with multiple controllers from other dimmer channels. This may be carried out as so many single-channel communication lines, or can be received as a single Kanalkommunikati ⁇ onstress for bus communication and the like, according to which messages thanks to a single address or a group address at the destination.
- the main control device is a channel control device.
- FIG. 1 shows the function distribution of a first he inventive multi-channel dimmer on the supply network and a load
- FIG. 2 shows the functional distribution of a second multichannel dimmer according to the invention on the supply network and a load
- FIG. 1 shows the functional distribution of a multi-channel D on the supply network N, LI.
- the multichannel dimmer D has a plurality of dimmer channels K1, K2, Kx, each of which is galvanically isolated from one another, each having a channel control device S1, S2, Sx.
- the dimmer channels are connected in parallel via output terminals AI, A2, Ax to the load L on the output side, so that everyone can supply a part of the current to them.
- the dimmer D starts due to an external command B.
- a main controller H generates control commands, which arrive via a communication link V to the channel control device Sl of the dimmer channel Kl.
- the dimmer channel Kl includes a measuring device Ml is geeig ⁇ net, to generate information about the behavior of electricity at a location in the channel, and in particular information regarding the zero-crossing of the voltage.
- the dimple channel Kl is therefore also called the dimming channel.
- a communication link transmits such information from the measuring device M1 to the channel control device S1.
- these Ka ⁇ nalkommunikationseducationen V12, V23, V (xl) x suited to information on the behavior of electricity in Messdim- merkanal Kl to the channel controller S2, Sx of the next dimmer channel K2, Kx to transfer, here from the channel controller Sl, S2 of a dimmer channel Kl, K2 to the channel control S2, Sx of the other dimmer channel K2, Kx.
- these channel communication links V12, V23, V (xl) x can also control the control commands of
- Dimmer channels Kl, K2, Kx each contain an optocoupler on both sides.
- the channel communication connections V12, V23, V (x-l) x between the dimmer channels K1, K2, Kx link the measuring device M to the respective channel control devices S1, S2, Sx for a very timely transmission.
- the channel communication links V12, V23, V (x-l) x are unidirectional, so separate communication links V provide the control commands of the main controller H to each dimmer channel K1, K2, Kx and return any feedback.
- FIG. 3 shows measuring dimmer channel K1, dimmer channel K2 and its channel communication connection V12 of the second inventive multichannel dimmer, wherein the circuits of measuring device M, channel communication connection V12 and dimmer channel K2 are simplified.
- a comparator N12 of the measuring device Ml analyzes this signal at zero crossings. The zero crossings are passed on directly to the channel control device Sl but also to an optocoupler in the channel communication connection V12.
- the optocoupler contains a
- the optocoupler transmits the information to the zero low-delay passes to the channel controller S2 and to the next channel communication link.
- the control commands of the main control device H similar to the variant of Figure 1 via a single communication link V to the channel control device Sl dimmer channel Kl.
- the channel control device Sl gives it ever ⁇ but the next dimmer channel K2 on
- such channel communication connections V12, V23, V (x1) x outlined in FIG. 3 are for example supplemented in front of the light-emitting diode with a switch and a resistor in a row to ground ,
- 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 thus impose small voltage steps on the signal, which lead to small intensity steps in the light of the light-emitting diode.
- the corresponding resistance steps in the photosensitive resistor on the receiver side can be detected by a simple voltmeter. However, they do not trigger a zero-crossing detection there. These steps thus encode the control commands of the main controller H and are forwarded by the voltmeter to the respective channel controller Sx + 1.
