Definitions

  • the invention relates to a module and a method for controlling a dimmable operating device and such a control gear.
  • an operating device also referred to as electronic ballast, electronic ballast
  • the operating device controls at least one lighting means, e.g. a fluorescent lamp, on.
  • the operating device is installed at the place of the luminaire (for example in the ceiling of a room). It has a 1-10V interface for dimming the at least one lamp according to DIN EN 60929 (VDE 0712-23).
  • DIN EN 60929 VDE 0712-23
  • the installation of control cables to the individual lights would require considerable construction effort and is often impractical. This is all the more true as in many installations several lights are switched on or off together with a single switch.
  • Another disadvantage is that common installations (e.g., existing light switches) do not have means for driving such a control line.
  • the object of the invention is to avoid the above-mentioned disadvantages and in particular to provide a possibility of realizing at least one second operating state of an operating device without a separate control line.
  • the state transition can advantageously be achieved by means of a conventional switch by the switch off briefly and turned on again.
  • no separate control cables to the operating devices of the bulbs are necessary, an existing installation can be added without changing the switch or lines to a flexible and cheap way to change the brightness of bulbs.
  • the operating device (also referred to as electronic ballast or electronic ballast) is in particular an operating device for a fluorescent lamp or (at least) a semiconductor light-emitting element (for example LED) or a halogen lamp.

  • the dimming state may be a state in which the module provides an input to an output of the module.
  • a voltage limit is bridged, i.
  • the module itself does not limit the voltage, but connects the input to the output. Accordingly, at the output of the module, e.g. a constant light controller are connected, the brightness dependent, for example by means of a sensor, adjusts the brightness of the bulb.
  • the switch actuator has a terminal, by means of which a switching operation or a switching between the dimming states can be detected.

  • the module may be made correspondingly small (e.g., in the form of a plug) so that it can be placed in the operating device or in the luminaire.
  • a next development consists in that, after the power interruption, a time duration up to an end of the power interruption can be determined and the short-term power interruption can be detected if this time duration is shorter or in particular equal to a predetermined time duration.
  • One embodiment is that, depending on the state transition, one of a plurality of dimming states of the operating device can be set alternately.
