Definitions

  • the present invention relates to a method of operating devices in a lighting system having a DALI bus. Furthermore, the present invention relates to a so-called converter unit for use in a DALI system and a lighting system with a DALI bus and a corresponding converter unit.
  • DALI Digital Addressable Lighting Interface
  • It is a communication protocol for the digital control, in particular of light source control gear, which makes it possible to transmit commands to several devices either in groups or individually, e.g. to adjust or dim the light sources within a certain brightness range.
  • This DALI standard not only enables the digital control of the devices but also allows lamp operating devices to send feedback to a central control unit with regard to the operating state, whereby defects of individual devices can be determined very simply and quickly. Furthermore, other devices such. As sensors or the like. Be integrated into the system.
  • a lighting system based on the aforementioned DALI standard has a bus line, the so-called DALI bus, to which all devices are connected.
  • This DALI bus is a data line separate from the general power supply, via which commands are sent to the devices, which are mainly electronic ballasts.
  • An individual control of individual devices is made possible by the fact that each device is assigned a single, individual operating address, via which it can be controlled.
  • the DALI standard offers the possibility of assigning group addresses in order to control several operating devices in a uniform manner.
  • each of the usable devices must have an individual address, the number of devices that can be connected to the system is necessarily limited.
  • Another problem is that in lights with multiple operating devices or lights that a regular operating equipment and an emergency light device for operating in Have emergency situations, each operating device must be assigned a single address, which further reduces the number of connectable to the system lights.
  • converter are devices that are connected to the DALI bus and that are capable of receiving incoming DALI commands on the input side.
  • these converters are connected to a plurality of DALIcompatible devices, which are grouped together by the converter in the context of so-called broadcast commands, ie with signals or commands that are transmitted without address to all devices simultaneously.
  • broadcast commands ie with signals or commands that are transmitted without address to all devices simultaneously.
  • the use of such converters is particularly useful when all devices connected to the converter on the output side are to be driven in the same way, which makes sense in some applications, for example if the associated lights are within a common area.
  • a disadvantage of this solution is that in this way the output-side devices can actually basically only be controlled uniformly.
  • the DE 10 2009 019 656 A1 relates to a control device for driving a lamp or lighting arrangement, wherein the lighting arrangement has at least two operating devices for operating light sources connected to the operating devices, wherein the control device input terminals for receiving external control commands, output terminals for transmitting operating device commands to the operating devices of the lamp or lighting arrangement and a control unit which is designed to generate the operating device commands on the basis of the received external control commands.
  • the control of the individual operating devices by the controller can be done by means of commands in the DALI standard. Furthermore, it is possible to control the operating devices via broadcast commands according to the DALI standard. It is also possible to use DALI addressing commands or DALI commands to special addresses that were previously assigned to the corresponding operating device.
  • the solution according to the invention is based in turn on the idea of using the above-described converter or converter units to increase the number of devices to be used, which are designed for connection to a DALI bus and are connected to a DALI bus assigned to the converter unit. Operating address are accessible via the bus. On the output side are to the converter units other DALI-compatible devices connected, the converter unit in normal operation, these devices with broadcast commands, ie uniformly controls. However, according to the invention, at least temporarily, the converter unit can be placed in a so-called transparent operating mode or tunnel mode. In this transparent operating mode, the converter unit is able to individually address one of the devices connected on the output side under an individual address.
  • This individual address is relevant here exclusively for the communication between the converter unit and the selected device connected on the output side, but not for the communication of the converter unit via the actual DALI bus.
  • a central control unit connected to this DALI bus one of the devices connected on the output side to the converter unit according to the invention can then be addressed conventionally in the context of this transparent operating mode, namely under the DALI operating address of the converter unit.
  • feedback from the selected device in terms of its operating state via the converter unit to the central control unit are transmitted, ie, there are all control and query options that arise within the framework of the DALI standard, temporarily usable for this one device.
  • a converter unit for use in a lighting system, wherein the converter unit is provided for connection to a DALI bus and is configured to communicate via the DALI bus under a DALI operating address assigned to the converter unit and devices connected on the output side to the converter unit, which are likewise designed to communicate in accordance with the DALI standard, to jointly or uniformly control them.
  • the converter unit is designed in a transparent operating mode to individually address one or a selected one of the devices connected on the output side under an individual address.
  • the invention proposes a method for operating devices in an illumination system, wherein the illumination system has a DALI bus, to which a plurality of devices are connected, which are designed to be driven and communicate according to the DALI standard, wherein at least one the device is a converter unit which is designed to communicate via the DALI bus under a DALI operating address assigned to the converter unit and devices which are connected to the converter unit on the output side and which are likewise designed in accordance with the DALI bus Standard to communicate, to jointly or uniformly control, and wherein according to the invention, the converter unit responds individually in a transparent operating mode of one of the devices connected on the output side under an individual address.
  • the converter unit In the transparent operating mode, the converter unit is designed to forward instructions arriving at the input, but to replace the DALI operating address assigned to the converter unit in the DALI commands by an operating address assigned to the selected device connected on the output side. Furthermore, in view of the possibility of forwarding feedback, the converter unit can be designed to forward feedback from the input-side device via the input-side DALI bus, but the operating address of the device contained in the feedback is assigned by the converter unit DALI operating address to replace. When forwarding commands or responses, therefore, the operating address of the converter unit is replaced by intended for the communication between converter unit and device operating address or it is carried out an exchange of addresses in the opposite direction. Ultimately, this results in the effect described above, namely that from the perspective of a central control unit in the transparent operating mode under the DALI operating address of the converter unit, a device is individually controlled and can also transmit feedback to the central control unit at this address.
  • a directly resulting from the invention further advantage also consists in the fact that it is no longer absolutely necessary that it is at the output side connected to the converter unit devices of the same type.
  • one of the devices can now also be a sensor, since the signals provided by this sensor can be interrogated at any time in the context of the transparent operating mode. The resulting control options and options for the design of the lighting system are therefore significantly increased.
  • the switching of the converter unit according to the invention into the transparent operating mode can take place in different ways.
  • the special commands available within the framework of the DALI standard in particular commands, by which reference is made to an entry in the so-called memory bank of the converter unit, are used.
  • this entry in the memory bank at the same time also identify the individual address, under which the converter unit with the in the context of transparent operating mode selected or selected output device communicates.
  • the leaving of the transparent operating mode can in turn preferably take place when a non-individually addressed DALI command, in particular a group-addressed command, is transmitted to the converter unit. This can then be interpreted by the converter unit to the effect that it is intended to change to the regular operating state in which the devices connected on the output side are again controlled uniformly with the aid of broadcast commands.
  • the addresses for communication between the converter unit and the output-side devices can be assigned within the scope of all options available for the DALI standard.
  • the DALI standard itself provides different variants for address assignment, whereby it is only necessary that each device is assigned an individual address. It may, for example, be random addresses assigned individual addresses. Furthermore, it is also possible in advance to assign addresses to the devices manually or by other programming operations.
  • FIG. 1 shows the structure of a lighting system according to the invention generally designated by the reference numeral 1, wherein a communication according to the DALI standard is provided.
  • the central component of the system 1 is therefore a bus line 2, the so-called DALI bus, to which the various subscribers of the system 1 are connected.
  • the lines for powering the various participants of the system 1 since the way the power supply for the inventive concept does not matter.
  • the illustrated lines are used in the present case, therefore, only the communication between the various devices.
  • the DALI standard is based on the so-called master-slave principle, that is, a unit of the system 1 is authorized to give on its own control commands to the bus line 2 to contact and control the various participants and possibly to request feedback.
  • a so-called DALI controller 100 that is to say a central control unit which gives control commands to the bus line 2. These are then transmitted to the various devices which are connected to the bus line 2.
  • These devices 10 and 110 can be very different devices, provided they are able to communicate according to the DALI standard.
  • the devices provided with the reference numeral 110 are electronic ballasts or, in general, operating devices for operating light sources.
  • These devices are thus integrated into luminaires and designed to implement input side incoming from the central control unit 100 DALI commands such that the light sources are adjusted in their brightness accordingly. It would also be conceivable beyond the connection of sensors via which an automated control of the lights can be done. These may be brightness or presence sensors. The signals provided by these sensors are interrogated by the central control unit 100 and then converted into corresponding commands for controlling the operating devices 110.
  • the lighting system 1 could, of course, be extended to the effect that the central control unit 100 receives information for controlling the lighting from a higher level again.
  • This is shown in FIG. 1 schematically by a further unit 200, which communicates with the control unit 100.
  • a further unit 200 which communicates with the control unit 100.

  • the latter also receives commands arriving via the bus line 2 from the central control unit 100 in accordance with the DALI standard and accordingly has, like all other devices, which are connected to the bus 2, a her individually assigned DALI operating address. Commands which contain an individual operating address are thus processed exclusively by the corresponding device. In this way, the DALI standard offers the possibility to individually and individually control luminaires.
  • the converter unit 10 does not constitute an operating device, via which associated light sources are operated directly. Instead, their function is to control connected devices on the output side.
  • FIG. 1 Thus, in turn, several devices 20 1 to 20 4 and 30 are connected on the output side via a control line 12 to the converter unit 10 and form an independent group within the lighting system 1.
