Definitions

  • the present invention relates generally to interfaces for lamp operating devices, such as electronic ballasts for gas discharge lamps.
  • the invention further relates to lamp operating devices with such interfaces and to methods for controlling a lamp operating device by means of an interface.
  • Fig. 7 discloses an example of an interface to which signals from a push button / switch or digital signals from a bus can be selectively applied.
  • a connected electronic ballast can be switched on or off, for example, by pressing a button.
  • a setpoint for a brightness control can be achieved by a corresponding time duration of the push-button operation, since the connected evaluation logic of the interface converts the duration of the push-button operation into a setpoint signal for the electronic ballast (ECG).
  • ECG electronic ballast
  • a galvanic isolating element 4 such as an optocoupler provided.
  • the digital signals supplied from a bus, for example, are transmitted via this galvanic isolating element 4 to the evaluation logic 3, which is thus located behind the galvanic isolating element 4 as seen from the bus.
  • the evaluation logic 3 since the evaluation logic 3 must respond to incoming signals from the terminals of the interface 12 out immediately, there is the problem in the prior art that the lamp operating device can never be turned off completely, otherwise the evaluation logic would be switched off with.
  • the evaluation logic must therefore be constantly supplied with mains voltage 15, which is reflected in corresponding standby losses (power that drops in standby mode).
  • Standby losses are at odds with the enormous efforts that have been made lately in energy saving in the lamp industry.
  • the WO 02/082618 A1 which shows a way to reduce standby losses in a DALI interface.
  • a DALI processor is placed in a standby mode when no signals are transmitted on the connected DALI bus. Otherwise shows Fig. 3 of the WO 02/082618 A1 an example of the generally prevailing trend that the Ausretelogik seen from the DALI bus behind the galvanic separating element (insulation 310 in Fig. 3 ) must be arranged.
  • the present invention now has the object to reduce the standby losses in an interface for a lamp operating device.
  • the evaluation logic can be designed to transmit commands to the connected lamp operating device by means of the galvanic separating element, by means of which commands the lamp operating device can be separated from the mains voltage.
  • the lamp operating device may be separable from the mains, for example, by means of a relay or an optocoupler-controlled triac.
  • the evaluation logic can be designed to transmit control values to the connected lamp operating device by means of the same and / or by means of a separate galvanic separating element.
  • control values for example, set values for a lamp brightness control
  • a high-level signal is applied to the input-side terminals.
  • this high-level signal is used to supply power to the evaluation logic. This would be obviously not possible if, as in the prior art, the Ausretelogik considered from the bus behind the galvanic separation element.
  • an interface for a lamp operating device such as an ECG for a gas discharge lamp
  • has an evaluation logic which is supplied by at least one input-side signal terminal of the interface with voltage.
  • the invention also proposes a method for controlling a lamp operating device by means of an interface in which, for example, via a bus incoming signals are processed first, for example, by a Ausretelogik and converted into control signals for a lamp operating device before being transmitted by means of a galvanic separating element to the lamp operating device become.
  • the conversion of the incoming signals is thus carried out before the transfer of the converted control commands via the Galvanic separator.
  • control signals are applied to at least one input-side terminal 1, 2 of an interface circuit 12 according to the invention.
  • connection 1, 2 for a bus line pair or a button / switch are shown, it should be emphasized that the present invention can also be applied to the interface for connecting a single signal line.
  • the control signals can be, for example, digital signals (for example according to the DALI standard) or signals from a pushbutton / switch.
  • an evaluation logic 3 is provided which converts the control signals supplied to the input-side terminals 1, 2 into control signals for a ballast electronics 13. These already converted control signals are transmitted from the evaluation logic 3 via a galvanic coupling, for example.
  • the ballast electronics 13 is supplied in a known manner with mains voltage 15.
  • the evaluation logic 3 is not supplied by means of the mains voltage supply 15 of the operating device (ballast here), but via the input-side terminals 1, 2 (for example, bus lines) with energy.
  • the evaluation logic 3 is therefore independent of the power supply of the operating device with respect to their power supply.
  • the evaluation logic 3 according to the invention is thus part of the interface 3 and no longer part of the operating device 13 as in the prior art.
  • the evaluation logic 3 may, for example, be designed as an ASIC, microcontroller or DSP.
  • the evaluation logic 3 is designed so that it is activated only when a change of the bus line to a high level signal by this voltage (wake-up), which Activation is sufficiently fast to ensure a secure detection of the first bit of the incoming digital signal.
  • Fig. 2 shows in a detailed view, the interface circuit 12 with the evaluation logic 3 and the galvanic coupling 4.
  • the ballast electronics 13, however, is in this Fig. 2 (as also explained in the following Fig. 3 ) not described further.
  • a high-level signal is known to be present at the input-side terminals 1, 2 of the interface circuit 12 in the idle state, so that this high-level signal is used by means of a constant current source 5 (impressed current) and a diode 7 as the power supply 8 for the evaluation logic 3 can be.
  • the evaluation logic 3 detects by means of a voltage divider to the input-side terminals 1, 2 applied control signals (in the DALI standard, for example, the edges of the digital signals), it implements according to a logic implemented in the evaluation logic 3 in control signals and supplies these output control signals 23 to the galvanic separation element 4, according to the embodiment of FIGS. 2 and 3 is designed as an optocoupler.
  • a voltage divider to the input-side terminals 1, 2 applied control signals (in the DALI standard, for example, the edges of the digital signals)
  • it implements according to a logic implemented in the evaluation logic 3 in control signals and supplies these output control signals 23 to the galvanic separation element 4, according to the embodiment of FIGS. 2 and 3 is designed as an optocoupler.
  • other galvanic separating elements such as transformers, etc., are conceivable.
  • the evaluation logic 3 of the input-side terminals 1, 2 of the interface 12 seen from arranged in front of the galvanic separation element 4 and thus is a genuine part of the interface 12. Furthermore, it should be noted that the evaluation logic 3 is not based on the mains voltage supply 15 of the operating device 13, but starting from the signal input terminals 1, 2 of the interface 12 is supplied with voltage.
  • the galvanic coupling 4 may be formed as optocoupler-controlled triac, which can separate the entire ballast electronics 13 from the mains voltage 15 depending on the control by the evaluation logic 3. In this case fall in the ballast 13 in standby mode no more losses.
  • ballast 13 eg the inverter
  • Fig. 5 The embodiment according to Fig. 5 is opposite to that of Fig. 4 extended to the effect that the evaluation logic 3 (known in 4 and 5 not shown) not only controls a galvanic isolating element 4 for switching on / off the mains voltage 15 for the ballast electronics 13, but also about the same or as in Fig. 5 shown, a separate galvanic separating element 20 control values (for example, set values) for the lamp control 19 and other signals transmitted.
  • the galvanic isolating element 20 (in the exemplary embodiment, an optocoupler) may be designed to be bidirectional and, in addition to the first transmission branch 22 for the manipulated variables, also have a feedback branch 21 for status information and / or error messages from the lamp control 19 or others To transfer components of the ballast electronics 13 via the branch 21 of the galvanic isolator 20 to the evaluation logic 3, so that these corresponding digital signals (24 in accordance with Fig. 3 ) can output at the terminals 1, 2 of the interface 12.
