  • Fig. 2 shows an exemplary interface circuit, as shown in the in Fig. 1 could be used.
  • the switched mains voltage Vn is supplied to a rectifier circuit 100 via a resistor R7a of, for example, 20 ⁇ .
  • the rectifier circuit 100 consists of four diodes D1a, D2a, D3a, D4a. These are connected to ground in a conventional bridge rectifier circuit.
  • the rectified signal is supplied to a zero-crossing detection circuit 101. This consists of two transistors Q1a, Q2a and two resistors R1a, R2a.
  • the emitter of the transistor Q1a and the resistor R1a of, for example, 332 ⁇ are directly connected to the rectified signal.
  • the resistor R1a is further connected to the base of the transistor Q1a and the emitter of the transistor Q2a connected.
  • the collector of the transistor Q1a in turn is connected to the base of the transistor Q2a and the resistor R2a of, for example, 150 K ⁇ .
  • the collector of the transistor Q2a is further connected to the second side of the resistor R2a.
  • the signal exits the zero-crossing detection circuit.
  • the signal is fed via an additional diode Z3a to an optocoupler Q4a.
  • This is connected via a further resistor R3a, for example, 10k ⁇ with a supply voltage V2, for example, 15V.
  • the interface signal can be taken from the secondary side of the opto-coupler Q4a.
  • the zero-crossing detection circuit 101 generates a pulse every zero crossing of the applied signal. Depending on the steepness of the voltage passage through the zero point results in a different width pulse. Such a pulse typically has a duration of 100 microseconds. Such a pulse is well transferable by the optocoupler Q4a.
  • Fig. 3 shows an exemplary waveform in an interface circuit, such.
  • a control signal 10 has a frequency of 50 Hz and thus a period of 20 ms.
  • the interface signal 11 has only individual pulses 12 at the zero crossings of the control signal 10. Shown here is the trouble-free case.
  • the interface signal on the secondary side of the optocoupler Q4a can now be evaluated with regard to the detected zero crossings. On the basis of the recognized sequence of zero crossings can thus be concluded on the operation of the button, as for a certain period (eg in the range of 400 to 1000 milliseconds) a mains voltage was supplied to the interface circuit.
  • Disturbances can produce steeper signal paths in the areas of the zero crossings of the control signal.
  • the pulse duration decreases drastically in this case. This can go so far that the optocoupler Q4a out Fig. 2 the signal can no longer be transmitted properly.
  • Threshold values of -6.5V to 6.5V amplitude of the mains voltage are typically provided to detect the zero crossings. These threshold values should not be changed, as the interface should advantageously also be used for digital DALI signals, and the DALI digital LOW signal should be below 6.5 V.
  • the problem of the invention thus exists in particular at interfaces of operating devices for lamps, which are to process both digital signals, as well as AC signals.
  • Fig. 4 shows an embodiment of the operating device according to the invention for lighting means.
  • a switched mains voltage Vn is supplied to a rectifier circuit 200 via a network resistor R network of, for example, 20 ⁇ .
  • the rectifier circuit 200 largely corresponds to the rectifier circuit 100 Fig. 2 , Four diodes D1 - D4 are connected in a common bridge rectifier circuit to ground.
  • the rectified control signal is transmitted from the rectifier circuit 200 to a zero-crossing detection circuit 201.
  • a first resistor R1 of, for example, 332 ⁇ and the emitter of a first transistor Q1 are supplied with the rectified signal.
  • the second side of resistor R1 is connected to the base of this first transistor Q1.
  • the collector of the first transistor Q1 is connected to the base of a second transistor Q2 connected.
  • the base of the first transistor Q1 is connected to the emitter of the second transistor Q2.
  • the base of the second transistor Q2 is further connected to the first side of a second resistor R2 of, for example, 150k ⁇ . This resistor R2 is connected to ground.
  • the output of this zero-crossing detection circuit is applied to the collector of the transistor Q2 and is supplied from this Zener diode Z2.
  • the control signal Vn is further supplied to a peak detection circuit 202 via the network resistor R Netz . It first passes through a Zener diode Z1. Since the Zener diode Z1 forms a kind of threshold value switch with its predetermined breakdown voltage and only turns on when a predefined threshold voltage is exceeded, only the peak values above a predetermined upper threshold value of one of the two half-cycles of the alternating voltage signal pass through the Zener diode Z1. Signal components which lie below the breakdown voltage of the Zener diode Z1, ie below the predetermined upper threshold value, are not forwarded. This includes, in particular, the second half-wave of the alternating voltage signal Vn. Instead of the Zener diode Z1, it is also possible to use a resistance divider which is dimensioned to the threshold voltage of the transistor Q3.
  • the resulting signal is supplied to the base of a transistor Q3.
  • the emitter transistor Q3 is connected via an ohmic resistor R5, for example, 10k ⁇ to the Base of transistor Q3 and continue to ground.
  • This transistor Q3 provides a uniform rectangular pulse shape.
  • the output signal of the peak detection circuit 202 is applied to the collector of the transistor Q3 and is supplied from this also the Zener diode Z2.

  • the actual transmission of the interface signal is effected by the secondary part of the optocoupler Q4.
  • a resulting signal of the interface circuit Fig. 4 can in Fig. 5 be seen. So shows Fig. 5 the control signal 10 and at the same time the interface signal 21, which corresponds to the output signal of the optocoupler. For clarity, different scales were used for the two signals.
  • the interface signal 21 now has both pulses 23 at the zero crossings of the control signal 10, as well as wide pulses 22 in the range of the peak values of the positive half cycle of the control signal 10 (ie when the upper threshold value is exceeded). Connecting the peak detection circuit 202 to the inverted input of the rectifier circuit 200 would result in a wide pulse 22 at the level of the negative half wave of the AC signal 10.
  • the pulses 23 at the zero crossings of the control signal 10 result because the zero-crossing detection circuit 201 in conjunction with the Zener diode Z2 only transmits a current when the voltage of the control signal 10 has exceeded some potential (both positive and negative).
  • some potential both positive and negative.
  • the voltage of the control signal 10 has exceeded some potential (hereinafter referred to as the lower threshold) (due to the rectifier D1-D4 in both the positive and negative directions), the current flowing through the zero-crossing detection circuit 201 is sufficient to drive through the Zener diode Z2 and a current flows through the primary side of the optocoupler Q4, whereby the optocoupler Q4 on the secondary side drives through.
  • the lower threshold some potential
  • the optocoupler Q4 on the secondary side drives through.
  • an interface signal 21 with a low level 24 is therefore present during the negative half-wave for a large part of this half-cycle, which can be interpreted as logic "0".
  • a concern of a network voltage is detected by the fact that for the interface signal 21 regularly for the duration of almost a network half-wave, ie at least 9 ms, a low-level signal 24 is applied.
  • a concern of a mains voltage so the operation of the button, by evaluating a longer phase of the concern of a signal with a low level 24 (ie, the reception of a logical "0") take place.
  • the bipolar coupled noise voltage will only make a contribution in the branch to the rectifier with the diodes D1 - D4, provided that the injected voltage at least sufficient that this voltage exceeds the lower threshold and thus the zero crossing detection circuit 201 in conjunction with the Zener diode Z2 lets a current through.
  • Each rectified half-wave of the control signal Vn thus generates from the exceeding of the lower threshold, a certain current flow by means of Transistors Q1 and Q2 at the input of optocoupler Q4.
  • a current flow through the primary side of the optocoupler Q4 is interpreted on the output side as logic "0" (analogous to the DALI standard, which leads to a voltage of more than 0 V in the high state).
  • the duration of such a signal with logic "0" is only in the range below 5 ms.
  • Fig. 6 is an exemplary waveform in the operating device according to the invention after Fig. 4 shown with open line and a capacitive fault.
  • the capacitively coupled mains voltage 31 has a phase offset of 90 ° with respect to the control signal 10. Since the button is not pressed, the interface circuit detects no zero crossings of the actual mains voltage 10. Instead, the zero crossings of the capacitively coupled signal 31 in the interface signal 30, which corresponds to the output signal of the optocoupler detected. This results in pulses 32, 33 in the interface signal.
  • the subsequent drive circuit accepts the signal not valid signal and thus not as an indication the operation of the switch or button.
  • the Threshold of the Zener diode Z1 upper threshold
  • the transistor Q3 is turned on, whereby the point in front of the Zener diode Z2 is pulled to a voltage of 0V, which in turn is interpreted in the interface signal 30 on the output side as logic "1".
  • the half-wave of the reverse polarity of the upper circuit branch is not used, ie the transistor Q3 is never turned on.
  • the zero-crossing detection circuit 201 in combination with the Zener diode Z2 a current flow through the transistors Q1, Q2 will always result for this majority half-wave, which on the output side is interpreted as logic "0".
  • a logical "0" from a time duration above a threshold of e.g. B. at least 9 ms during a first half-wave can therefore only be generated when a deliberate mains voltage is applied. If the zero crossings are filtered out, the pulses with a level of logic "0", ie with a low level, last at least 10 ms. In addition, only with conscious application of a Mains voltage of the upper circuit branch can be activated with the Zener diode Z1. Primary side so flows at a noise voltage in each half-wave for a much shorter period than the duration of a half-wave power.
  • the interface circuit 2 detects exceeding the lower threshold for at least the majority of the duration of one of two half-waves of the control signal 10, and that the interface circuit 2 for each detection of exceeding the lower threshold, a low level signal pulse 24 in the Interface signal 21 is generated, and upon repeated succession of such low-level signal pulses 24 detects the presence of a control signal 10.

  • 10 pulses 55 are generated in the region of one half-wave of the injected signal 51.
  • pulses 52, 53 are generated in the region of the zero crossings of the injected signal 51.
  • a distinction between a coupled-in signal 51 and an applied network signal 10 is no longer possible.
  • the phase shift between the network signal 10 and the injected signal 51 results in an asynchronism of various connected devices and faulty circuits.
  • cable lengths of more than 500m are unusual for a luminaire or lighting installation and therefore this case need not be considered further.
