  • the thus calculated current value at the end of the freewheeling phase I ⁇ is compared with a setpoint value and if I ⁇ is greater than the desired setpoint, then the next clock increases the time period tQff between a switch-off and a subsequent switch-on. If the current I ⁇ is smaller than the desired value, on the other hand tQff is shortened at the next cycle.

  • the current value I ⁇ at the end of the freewheeling phase can be calculated relatively simply, since the calculation in the digital domain is reduced to a bit shift as well as a subtraction.
  • the present invention ensures that the current flow through the at least one light-emitting diode 7 never drops to zero, ie, the invention relates in particular to the continuous conduction mode. This results in the smallest possible ripple of the current flow through the at least one light emitting diode. 7
  • the inventive method is shown in the overview in Fig. 7 again schematically.
  • step SO begins in step SO with the end of the freewheeling phase F.

  • step S5 if it is determined in step S5 that the return flow I ⁇ does not correspond to a desired value, it is checked in the following step S6 whether the return flow I ⁇ is greater than the desired value. If so, in a following step S9 the next off time is increased, otherwise in a following step S8 the following off time is reduced.

  • the calculation made in step S4 can in this case be based on one of the three methods mentioned, depending on the presettings and the recorded measured values.
  • Another possibility of the regulation is that the increase in the current value detected by the current sensor 6, 12 is evaluated. The difference between the current value at the beginning and at the end of the switch-on phase is determined. From the rise of the current can be closed to the size of the inductor 3 or the forward voltage of the LED 7.

  • the drop in the current in the freewheeling path results from the quotient of voltage across the inductance 3 and the value of the inductance 3 multiplied by the switch-off time. Since during the freewheeling phase the voltage across the inductance corresponds approximately to the voltage across the light emitting diode 7 (the difference results from the forward voltage the freewheeling diode 2).
  • both the forward voltage of the light-emitting diodes 7 and the inductance 3 can be determined.

  • the switch S is turned on, according to the circuit of FIG. 3, the voltage across the inductance 3 can be measured via a voltage measurement at the connection point between the inductance 3 and the light-emitting diode 7. If both components are interchanged, the forward voltage across the light emitting diode 7 can be measured in a simple manner. Such a voltage measurement can also be used for fault detection. Thus, for example, an error of the light-emitting diode 7 or even a fault caused by a fault in the wiring of the light-emitting diode 7 such as a short circuit can be concluded.
  • a temporal monitoring of the detected current values can be carried out. If a change in the detected current values is detected, it is possible to infer a possible fault or also an aging of the light-emitting diode 7 or of other components. Also for the calculation of the required turn-off time t Off on the basis of the increase of the current through the switch S during a switch-on phase E, the already explained method of taking into account the blanking times tbik can be used.

  • the actually achieved current value I A at the end of the freewheeling phase F can then be compared with a predefined setpoint value and the time period t off can be adjusted again.
  • Such a digital circuit advantageously has at least one analog-to-digital converter for detecting the current and voltage values, a computing block for processing and calculating the corresponding values, and a memory register for storing the measured values and calculated values.
  • An advantageous design of the operating circuit according to the invention can be designed so that only the current for the regulation of the current through the light emitting diode 7 during the switch-on phase is measured and evaluated, while an existing voltage detection is used only for an error shutdown.

  • the inductance 3 is magnetized.
  • the switch-off phase F over a period of time toff, the inductance 3 is demagnetized, the current flowing through the light-emitting diode 7 and the diode 2.
  • the inventive method can be used for all circuit topologies for the operation of light-emitting diodes, in which no direct measurement of the Current through the LEDs is possible because the LEDs are not directly connected to ground, but are connected to a variable to ground potential.
  • This method can therefore also be used in operating circuits with potential separation, wherein during a switch-on phase E an inductance 3 is magnetized and is demagnetized in a subsequent switch-off phase F while driving a current through at least one light emitting diode 7.
  • the inductor 3 may have a secondary winding through which it outputs its energy during the turn-off phase F, whereby the potential separation is achieved in the circuit.
  • Such a circuit may be, for example, a forward converter.
  • the current is detected and evaluated by a switch (and the current increase) during a switch-on phase E and the necessary switching behavior of the switch 5 (for example, the (switch-off) time period t of f) is determined
  • the present operating circuit and the present method for operating at least one light-emitting diode thus yields that regardless of the load, for example, regardless of the number of light-emitting diodes supplied, the current profile is always between a value I max and a value - "- held min, ie that always with the same value I mj _ n > 0, the switch 5 is switched on again
