Definitions

  • the present invention relates to an interface device for a lamp operating device according to the preamble of claim 1 and an electronic ballast for gas discharge lamps or an electronic transformer for halogen lamps with a corresponding interface device.
  • the electronic ballast shown in FIG. 3 schematically shows the structure of a known electronic ballast for operating a gas discharge lamp 10, control signals a for dimming the electronic ballast or the gas discharge lamp 10 connected to it being supplied to the electronic ballast via an interface 1.
  • the electronic ballast shown in FIG. 3 comprises a rectifier 4 and an inverter 5, in the load circuit of which the gas discharge lamp 10 is arranged.
  • the rectifier 4 converts that from a supply voltage source, e.g. a mains voltage source, alternating voltage supplied into a rectified intermediate circuit voltage, which is fed to the inverter 5.
  • the inverter 5 typically comprises two controllable switches (not shown) connected in series, e.g.
  • MOS field effect transistors which are alternately driven by the rectified intermediate circuit voltage, so that one of the switches is always on when the other switch is off.
  • An output connection of the inverter 5 is connected on the one hand to the connection point between these two alternately controlled switches and on the other hand to a series resonance circuit consisting of a coil 6 and a capacitor 7, the capacitor 7 of the series resonance circuit being connected in parallel with the gas discharge lamp 10 via a coupling capacitor 8.
  • the alternating activation of the switches of the inverter 5 generates a clocked, ie “chopped”, high-frequency AC voltage on the output side of the inverter 5, which serves as the operating voltage for the gas discharge lamp 10.
  • the output frequency of the inverter 5 is shifted into the vicinity of the resonance frequency of the series resonant circuit with the coil 6 and the capacitor 7, so that a voltage surge occurs on the capacitor 7, which ultimately leads to the ignition of the gas discharge lamp 10.
  • a heating transformer can be provided with a primary winding 9A and secondary windings 9B and 9C, the primary winding 9A being connected to the series resonant circuit, while the secondary windings 9B and 9C are each connected to one of the lamp filaments are connected in parallel.
  • the secondary windings 9B and 9C By connecting the secondary windings 9B and 9C to the.
  • Lamp filaments of the gas discharge lamp 10 it is possible to supply the lamp filaments with energy even when the gas discharge lamp 10 is in the ignited mode.
  • the interface 1 of the lamp operating device shown in FIG. 3 is designed as an analog 1-10V interface.
  • the external control signals received by the interface 1 are fed directly to a control unit 2 of the electronic ballast via an appropriately designed input transformer of the interface 1, the control unit 2 e.g. controls a bridge driver 3 of the inverter 5.
  • the interface automatically sets a minimum dimmer corresponding to 1V, for example, so that control voltages ⁇ 1V have no direct influence on the dimming process, since they are regarded as a 1V control voltage.
  • Another interface device for controlling a lamp is known from DE 33 45 559 A1. This is connected via lines to several remotely located switches, control pulses for operating the lamp being generated by the interface device depending on the position of these switches.
  • an interface to a serial data bus can also be used, the corresponding control commands then being transmitted in digital form.
  • WO 97/06655 also describes an electronic ballast for operating a lamp, in which an interface device is used. This is designed in such a way that it is able to distinguish different methods for transmitting dimming commands via a modification of the supply voltage and accordingly to generate control signals for the lamp. In this way, a very flexible use of the electronic ballast is made possible.
  • Dimming control signals are received and transmitted.
  • the control unit 2 controls, for example, the bridge driver 3 in such a way that it changes the frequency or the duty cycle of the alternating voltage supplied by the inverter 5 by switching the on and off times of the two to a full or half bridge interconnected inverter switch of the inverter 5 can be varied accordingly.
  • the known interface 1 shown in FIG. 3 is not able to receive switch-on and / or switch-off commands and to forward it accordingly to the electronic ballast, ie the electronic ballast cannot be switched on and / or off via the interface 1. Rather, with the conventional interface 1, it is necessary to switch the lamp operating device on and off via the mains cable. However, this requires the use of additional relays, since the high starting currents must be taken into account, especially when switching on via the mains cable. This results in a significantly higher wiring and installation effort, whereby the individual relays must also be dimensioned accordingly to ensure reliable switching on and off.
  • the article "Smart Power IC Simplifies Dimmer Circuit" by Helmuth Lemmo, Electronics 24/1996, p. 106/107 describes a leading edge circuit for dimming a lamp.
  • External control signals can be supplied to the circuit, for example via an optocoupler, according to which the brightness of the lamp is changed.
  • the possibility of switching the lamp on and off the switching on taking place when the amplitude of the control signal exceeds a first limit value.
  • a second limit value which does not necessarily have to be identical to the first limit value
  • the lamp is switched off again.
  • This phase control circuit thus offers the possibility of switching a lamp on and off and dimming by means of a single control signal.
  • a disadvantage is that the circuit continuously consumes current even when the lamp is switched off in order to monitor the external control signal and to switch on the lamp when a dimming signal arrives.
  • the present invention is therefore based on the object of providing an interface device for a lamp operating device, which enables the electronic ballast to be switched on and / or off more easily without any major circuit outlay. At the same time, the power consumption of the interface device should be as low as possible.
  • the subclaims describe advantageous embodiments of the interface according to the invention, which in turn enable an improved function of the interface according to the invention and also ensure that the lamp operating device controlled by the interface can be reliably switched on and dimmed depending on an external control signal present at the interface.

  • the interface device is designed in such a way that it evaluates a received control signal and, depending on the received control signal, in particular depending on its amplitude, controls the operation of a lamp operating device connected to the interface device.
  • the control signals received are not simply transferred or forwarded to the electronics of the lamp operating device, but the interface evaluates the control signal present.
  • the interface either converts the control signal into corresponding dimming information for the lamp operating device or causes the lamp operating device to be switched on or off.
  • the interface according to the invention is also designed and connected in such a way that it is supplied with energy from the control voltage of the external control signal present at the interface during the start of the lamp operating device connected to it or during a standby mode, the interface, for example, a current of maximum 2 mA is supplied. In this way, the stand-by losses can be kept very low, since the interface or its electronic components are only supplied with power from corresponding internal power supply means when changing from stand-by mode to operating mode.

  • the dimming curve can be adapted to the sensitivity of the human eye.
  • the human eye is not linearly sensitive. This non-linearity is approximately logarithmic.
  • the use of a linear dimming curve for a desired brightness would not produce a corresponding linear brightness sensation in the human eye. For example, starting from a given brightness, the human impression of brightness is doubled by multiplying the electrical light output.
  • the microcontroller can be designed in such a way that it converts the external control signal or the Dinunsteli values contained therein according to a logarithmic dimming into the pulse-width-modulated dimming target information, which is finally output on the output side by the interface and in a lamp operating device connected to the interface for dimming the in turn connected to it Lamp can be used.

  • the supply voltage + V B builds up faster than the supply voltage -V B due to the resistors 54, 55 59 and 42. This has the effect that the supply voltage + V B has already been supplied to the microcontroller 31 via the connections H and I, and the microcontroller 31 is already supplied with a stable supply voltage and has run up when the supply voltage -V B at the output connection G of the power supply circuit 50 occurs, which leads to the blocking of the junction field effect transistor 60.

Obviously, 1 volt could be used as the limit value. However, in order to compensate for environmental influences or voltage fluctuations, the microcontroller 31 causes the lamp operating device connected to the connections C, D to be switched off taking into account a hysteresis, so that, for example, a voltage of 0.4-0.5 V is used as the limit value for switching off the lamp operating device can.
