Definitions

  • the present invention relates in general to a lighting system comprising a plurality of controllable lighting devices, and a central controller for individually controlling the lighting devices.
  • Lighting systems have been developed, wherein a central controller is capable of individually controlling a plurality of lighting devices.
  • One obvious way of implementation is a central controller having a plurality of outputs, wherein each individual lighting device is connected to a respective output, but this is complicated and would require a lot of electrical cables.
  • lighting systems have been developed comprising a common communication line running from one lighting device to the next.
  • the central controller issues digital command signals and address signals.
  • Each lighting device has a specific address, and is responsive only to the command signal associate with an address signal indicating its specific address. It is possible that two or more devices have the same address, which means that they will have the same response to the same command signal.
  • the lighting devices may receive power individually from a suitable power source, typically mains. However, it is also possible that the lighting devices receive power via the common communication line.
  • DMX Digital Multiplex
  • DMX512 Digital Multiplex
  • US patents 6175771 and 7065418 it will be assumed that the DMX protocol is used, but it is noted that the invention is not restricted to this protocol since the invention can also be implemented using different existing or future protocols.
  • the central controller itself is capable of performing, for instance, dimming, but this would require the user to go to the central controller whereas it is much more convenient if the user could give the command for dimming at the location where the dimming is required, which may be remote from the central controller.
  • a decentralized control feature implies a separate control device located at some distance from the central controller. Such control device must be connected to the central controller in order to enable the central controller to issue the appropriate command signals. This involves the disadvantage that the central controller must be provided with inputs for connecting the control devices, that control lines must be arranged for connecting the control devices to the central controller, and that the central controller must be "told" by the user which lighting devices are to be influenced by the control devices. This would make the design of the central controller quite complicated and hence expensive.
  • the present invention provides a decentralized control unit having an input for receiving command signals from the central controller, having functionality for amending the received command signals, and having an output for outputting the amended command signals.

  • Figure 4 is a block diagram illustrating a decentralized control unit.
  • FIG. 1 schematically shows a lighting system 1 according to the prior art, comprising a plurality of controllable lighting devices 2, individually distinguished by the addition of an index between brackets.
  • Each lighting device 2 receives power from a suitable power source, for instance mains, but this is not shown in the figure for sake of simplicity.
  • the lighting system 1 comprises a communication system 3, comprising a central controller 10, device interfaces 20, and a communication line 30 comprising a plurality of line portions 31.
  • the central controller 10 has an output terminal 12 for providing command signals (by way of example: DMX command signals).
  • Each lighting device 2 has a corresponding device interface 20, for receiving and processing the command signals and generating lamp drive signals in correspondence with the received command signals.
  • Each device interface 20 has a device interface input 21 and a device interface output 22. Each device interface 20 is designed to provide at its device interface output 22 an output signal identical to the command input signal received at its device interface input 21.
  • a first line portion 31(0) connects the output terminal 12 of the central controller 10 to the device interface input 21(1) of a first device interface 20(1).
  • the device interface output 22(i) of a device interfaces 20(i) is always connected to the device interface input 21(i+l) of a next device interfaces 20(i+l) via a next line portion 3 l(i).
  • Figure 2 is a graph schematically illustrating the DMX communication protocol. It is noted that the present invention can be implemented in conjunction with different communication protocols.
  • the horizontal axis represents time, while the vertical axis represents the command signal Sc.
  • the figure shows a sequence of data packets, each data packet containing a command for a lighting device. Data packets are distinguished by a start byte and a stop byte, as is known. Further, the sequence of data packets is distinguished by a start code as well, as is known.
  • Each device interface 20 has a device address, which can be set by a user.
  • the address is set by means of DIL switches. If the interface comprises 8 such switches, which each can represent a value 0 or 1 , the address can be set at any value between 000000000 and 111111111, i.e. there are 512 addresses possible. However, the address can be set in a different manner, and the number of possible addresses may be more or less.
  • a command for a device having address n is included in the n-th data packet of the sequence of data packets, i.e. the sequence of data packets contains at least 512 successive data packets.
  • an interface having address n will be responsive to the data of the n-th data packet and will ignore all other data.
  • the devices may all have mutually different addresses, but it is also possible that two or more devices have the same address, which means that they constitute a group of devices which all respond in the same way.
  • Each interface will relay the data packets from its input through to its output. This means that the command signals in the line portions 31(i) are all mutually identical to each other.
  • FIG. 3 is a block diagram comparable to figure 1, illustrating a lighting system 100 according to the present invention.
  • the difference between the prior art system and the inventive system is the presence of at least one decentralized control unit 150.
  • this decentralized control unit 150 is a dimmer.
  • this decentralized control unit 150 is an event detector, for instance a movement detector or a time clock.
  • FIG. 4 is a block diagram illustrating the decentralized control unit 150, hereinafter indicated as DCU, in some more detail.
  • the DCU 150 has an input 151 for receiving an input command signal Sc 1N , an d has an output 152 for outputting an output command signal SCOUT-
  • the DCU 150 further has a user-settable mode switch 153, a user- settable address selection device 154, and a processor 155.
  • the DCU further has a user input for setting a desired dim level.
  • the DCU further has a sensor for sensing movement.
  • the processor 155 comprises a function input 156.
  • the DCU 150 is treated as any lighting device. Assume that a prior art system 1 of figure 1 is to be adapted by introduction of a DCU 150 between lighting devices 2(i) and 2(i+l). First, line portion 31(i) is removed. DCU input 151 is connected to the device interface output 22(i) of the device 2(i), and DCU output 152 is connected to the device interface input 21(i+l) of the next device 2(i+l).
  • the user For configuring the DCU 150, the user sets the mode switch 153 to select between a mode "all addresses" and a mode "one single address". For the "one single address” mode, the user sets the address selection device 154 to define one single address X. In the following, it is assumed that the user has set the "one single address” mode.
  • the processor 155 calculates an adapted output address command signal AC'(X)ou ⁇ on the basis of the input address command signal AC(X) 1N an d on the basis of the function input signal received at its function input 156.
  • the processor 155 calculates the adapted output address command signal AC'(X)ou ⁇ such that an addressed device interface either follows the original input address command signal AC(X) 1N or does not respond at all, depending on the function input signal. It will be assumed that the event sensor can only make a distinction between "yes, event detected” and “no, no event detected", and that the function input signal accordingly can take two possible values which will be indicated as “ 1 " and "0", respectively.
  • Each lighting device still receives a "normal" command signal Sc, containing "normal" address command signals AC(n).
  • a lighting device receiving an adapted address command signal AC(X) has no means of determining whether the address command signal originates from the central controller 10 or from a DCU, and has no means of determining whether the address command signal has been adapted: the adapted address command signal AC(X) complies with the communication protocol in all aspects.
  • the advantageous effect is achieved that lighting devices having a certain address X which are located downstream of the DCU have a different response as compared to lighting devices having the same address X which are located upstream of the DCU.
  • the present invention provides a lighting system (100) which comprises: a plurality of controllable lighting devices (2) each having an associated address (n); - a central controller (10) for providing a command signal (Sc) including address command signals (AC(n)); at least one decentralized control unit (150) comprising an input (151) for receiving the command signal (Sc 1N ) and an output (152) for outputting an output command signal (SCOUT) including address command signals (AC(n)ou ⁇ )-
  • Each lighting device is responsive to the address command signal (AC(n)) corresponding to its device address (n).
  • the lighting devices are arranged in series for passing on the command signal, such that the output command signal is always identical to the input command signal.
  • the DCU calculates, for at least one address X, an adapted output address command signal (AC'(X)ou ⁇ ) based on the corresponding input address command signal (AC(X) 1N ) and based on a function input signal received at its function input (156).
  • the DCU can take two or more bytes as input if a lighting unit requires more than one input byte in a command signal. For instance, it may be that a lighting unit requires RGB-signals for setting a colour. In such case, three successive data bytes would all have the same address information, and the order of the bytes may determine which is for R, which is for G, and which is for B.
  • the DCU makes the address command signal AC(X) for a certain address X equal to the address command signal AC(Y) for a certain address Y.

La présente invention concerne un système d'éclairage (100) comportant: une pluralité de dispositifs d'éclairage contrôlables (2) ayant chacun une adresse associée (n); un contrôleur central (10) pour fournir un signal de commande (Sc) comprenant des signaux de commande d'adresse (AC(n)); au moins une unité de commande décentralisée (150) comportant une entrée (151) pour recevoir le signal de commande (Sc1N) et une sortie (152) pour émettre en sortie un signal de commande de sortie (SCOUT) comprenant des signaux de commande d'adresse (AC(n)ouτ). Chaque dispositif d'éclairage est sensible au signal de commande d'adresse (AC(n)) correspondant à son adresse de dispositif (n). Les dispositifs d'éclairage sont disposés en série pour circuler le signal de commande, de sorte que le signal de commande de sortie est toujours identique au signal de commande d'entrée. L'unité de contrôle de données calcule, pour au moins une adresse X, un signal de commande d'adresse de sortie adapté (AC'(X)ouτ) différent du signal de commande d'adresse d'entrée correspondant (AC(X)IN) et en fonction d'un signal d'entrée reçu à son entrée de fonctionnement (156).
