Definitions

  • the present invention relates to the control of a plurality of illuminant operating devices from a central unit.
  • the light source is a gas discharge lamp 5, which is controlled by an electric ballast (ECG) 1 as a control gear.
  • ECG electric ballast
  • this electronic ballast 1 has a rectifier with power factor correction circuit (PFC, Power Factor Correction) 2, an electrolyte storage capacitor 4 and an RF inverter 3, which in turn via its output circuit 6, the gas discharge lamp 5 drives.
  • the DC voltage (bus voltage) is therefore only present within the ECG.
  • an emergency lighting control 7 may be provided.
  • the rectifier 2 in the electronic ballast 1 is usually supplied with alternating voltage 9, for example mains voltage.
  • the starting point for the present invention is to propose control for illuminant operating devices, which enables more cost-effective production of operating devices.
  • the central point of the invention is that the unit rectifier / PFC is no longer provided locally in each operating device, but centrally for several operating devices.
  • the connection between this center and the individual operating devices is carried out according to the invention via a DC output circuit.
  • the present invention deals with the aspect of how operating devices can be supplied in a simple manner via the DC output circuit not only with the required operating power, but also with control signals.
  • a method for controlling lamp operating devices by means of a central, supplied with AC voltage rectifier / PFC unit is proposed, said central unit supplies by means of at least one DC output circuit several light source operating devices.
  • the DC supply voltage of the output circuit is modulated in accordance with a powerline technology high-frequency digital control signals. These powerline control signals can then locally in the operating devices by there provided powerline demodulators from the DC output circuit be read and evaluated to control the respective associated bulb.
  • powerline is to be understood in the broadest sense as a signal transmission via a power supply. Fundamentals of powerline technology can be found in the book “Powerline Communications "by Klaus Dorstedt, Prentice Hall, June 2001 , are taken.
  • a powerline modulator for modulating supplied control signals to the DC output circuit can be provided in the DC output circuit or else in the central rectifier / PFC unit.
  • a switch-off command are transmitted, whereupon this switches off the associated lamp via a powerline control command.
  • the gas discharge lamp can be switched off by switching off the inverter in the electronic ballast.
  • the powerline modulator may be preceded by a switch, wherein the powerline modulator issues a turn-off command to the DC output circuit in the form of a powerline command when the upstream switch is placed in its off position.
  • This conversion of the switch position into a digital control command has the advantage that it avoids the problems of the formation of a spark gap when opening the switch, which are common in high-voltage DC switches.
  • signals can also be transmitted bidirectionally in accordance with the powerline technology, so that signals can also be transmitted from one operating device to the central one Rectifier / PFC unit can be transmitted.
  • the corresponding operating device has a powerline modulator.
  • fault and / or status messages can be transmitted from one operating device to the central rectifier / PFC unit or to another connected to the DC output circuit point having a powerline demodulator.
  • the powerline modulator can be provided separately (external) to the central rectifier / PFC unit and transmit signals regarding the operating state of a luminous means or the associated equipment to the rectifier / PFC unit.
  • the control commands may be individually addressable to operating devices and / or groups of operating devices in that the commands have an address header or an individual output circuit is assigned to the operating device (s) to be addressed. In the latter case, the addressing thus takes place by responding to that output circuit to which the device to be addressed is assigned.
  • Individual light sources and / or groups of light sources can thus be individually started and / or dimmed by means of the powerline control commands.
  • the powerline control commands can be modulated with an amplitude of less than 10%, in particular less than 5% of the DC voltage.
  • the requirements in the Powerline DC bus can be defined without regard to the requirements of network operators, so that the strict limitations of powerline technology as they prevail in public networks, must not be met. Namely, any high, high-frequency signal levels (modulation levels) in the DC bus cause no harm to the AC power supply.
  • a control system for light emitting devices comprises a central rectifier / PFC unit, hereinafter referred to as "central unit".
  • This central unit supplies by means of at least one DC output circuit several light source control gear.
  • the DC supply voltage is modulated in a powerline technology high-frequency digital control signals. These control signals can then be locally read out by powerline demodulators in the operating devices and evaluated for controlling the lighting device associated with the operating device.
  • a powerline modulator may be provided in the DC output circuit itself or in the central unit.
  • the powerline demodulator in an operating device can be designed to initiate a switch-off command, which it receives via the DC output circuit, the switching off of the respective associated light source.
  • a central processing unit comprising, for example, a rectifier 2 and a power factor correction circuit (PFC) 10 is provided for a plurality of illuminant operating devices 1, 1 ', 1 " also spatially separated from the control gear and can, for example, be centrally located for a room, a floor or even a building in a cabinet, etc.

  • a Light sensor 5 or a motion detector (not shown) may be connected.
  • the operating devices 1, 1', 1" are designed differently.
  • the corresponding operating device 3 is, for example, designed as a ballast with an inverter.

  • individual output circuits 12 may be provided for individual operating devices or jointly supplied groups of operating devices.
  • This DC output circuit has the advantage that it is less susceptible to parasitic effects than corresponding AC circuits.
  • Emergency lighting control units 7 or further control units 8 can be connected to the DC output circuit 11 or 12, and these devices can also read signals from the connected operating devices from the DC bus if they have a powerline demodulator.

  • Fig. 3 a technique is shown, as by means of the DC bus in a simple manner, the operating devices 1 not only supplied with voltage, but also can be controlled.
  • powerline control signals are high-frequency modulated onto the DC bus 11.
  • the stroke of the modulation can be, for example, 10 volts at 400 volts DC voltage.
  • the modulation swing is small compared to the level of the DC voltage and bpsw. is less than 10% and preferably less than 5% of the DC voltage level.
  • Doe modulation frequency may be, for example, in the MHz range.
  • a power-line (PLC) modulator 17 is provided which modulates the control signals 23 supplied from a higher-level controller onto the DC bus 11.
  • the higher-level control can, for example, be a DALI (Digital Addressable Light Interface) controller.
  • DALI Digital Addressable Light Interface

  • the PLC modulator 17 but also a simple, manually operable button or switch 18 may be connected upstream, so that the transfer of this switch 18th is converted into the off position by the PLC modulator 17 into a powerline drive signal for the DC bus 11.
  • This powerline control signal is then read out by a PLC modulator 15, evaluated and transferred to a local control unit 16 in the operating device 1.
  • the local control unit 16 ensures that the read-out powerline control signals are converted into a corresponding operating state control signal for the connected lighting means 14.
  • a light source can be switched on, switched off and / or dimmed or queried states of a control gear from the central unit (master / slave principle).
