  • the communication interface 6 can also be used to transmit the low-voltage supply (there is then both a data communication and an energy transfer). For example, a so-called active low data transmission can be used, wherein at rest, a level of a few volts, for example 12V, is applied. In the case of a coupling, for example via transformers, energy could nevertheless also be transmitted even if the communication interface 6 is electrically isolated.

  • yet another (and thus third) secondary winding 33 is magnetically coupled to the primary winding 20 of the transformer 19.
  • This secondary winding 33 feeds a rectifier with a diode 42 and a capacitor 43, serves to generate a primary-side low-voltage power supply V CCP .

  • a starting resistor R1 which supplies the control unit G with energy until the primary-side low-voltage supply V CCP is generated as expected, since the generation of the primary-side and also the secondary-side low-voltage supplies V CCP and V CCS a clocking of the second sub-module B (DC / DC converter). If the actual low-voltage power supply then started from the isolated converter (second sub-module B), the ohmic starting resistor R1 can be switched off again with the switch S3, so as to avoid electrical losses via the starting resistor R1 in the regular operation of the circuit.
  • the low-voltage power supplies V CCS , V CCP are obtained by means of a full-bridge rectifier. But it can also be used only a single diode for rectification.

  • the LED module F may be provided in a memory 4 associated with it, for example with an EPROM, FLASH or OTP.
  • the control unit E for example, an integrated circuit or a microcontroller of the second module 2 access the memory 4 of the LED module F, so as to selectively read out, for example, its memory contents.

  • the data in the memory 4 may be, for example, the runtime, manufacturing data, error logging, maximum value, minimum values (eg for current and voltage) and / or the temperature.

  • the control unit E of the second module 2 can refresh the memory 4 of the LED module F periodically or depending on the operating state or event.
  • the LED module F itself has no memory.
  • the corresponding data, for example the permissible forward current for the LEDs of the LED track 8 can in this case be written in the memory 51 assigned to the control unit E of the second module 2. This can be done during the production of the second module 2, for example.
  • the LED module F is provided with an identification tag, such as the operating data represents or at least represents an identification for the LED module F.
  • the identification tag is then read out by the control unit E of the second module 2 and stored, for example, in a memory assigned to the control unit E of the second module 2. This thus only once read data content of the identification tag can then be used for the further operation of the LED module F.
  • the identification tag can only be a pure identification.
  • the lamp management module (second module 2) would determine the identification data and then determine operating data independent of the LED module F, for example also a database content accessible via the external bus 10.
  • the approach has the advantage that thus the cost of the additional memory 4, for example, an Eprom of the LED module F can be saved.
  • the possibility of reading out the memory 4 of the LED module F by the control unit E has the advantage that a very different LED modules F can be combined with a lamp management module (second module 2), the required operating data being from the LED Module F can be read and the lamp management module (second module 2) can thus adapt flexibly to the connected LED module F.

  • an embodiment of the two or more LED channels 53, 53 ', 53 "of the LED module F is preferred such that the encompassed space comprises at least large areas of the Planck's white light curve.
  • the example above spans a triangle in color space that covers at least large areas of Planck's white light curve.
  • substantially every point of the Planck's white light curve can be driven, i. it can - as a result of a mixture of the light of the multiple LED channels - white light with different color temperature are emitted.
  • the different LED channels must be driven with different intensity, wherein the intensity can be achieved, for example, by amplitude modulation (current through the LEDs) and / or PWM modulation.
  • the light intensity of the respective LED is crucial, which is then recalculated into a electrical control variable with known efficiency of the LED.
  • the total light output should now remain constant even when departing from different color loci, in particular on the Planck's white light curve.
  • the minimum light output is present.
  • the drive intensities can then be calibrated for all other color loci to be approached, ie the intensities are 'artificially' scaled down for each color locus deviating from the minimum light output, so that ultimately in the spanned color space constant light is generated everywhere with the minimum achievable light output becomes.
  • the calibration factor can be calculated based on the known efficiencies of the LEDs used.
  • the total light output when departing different color locations in particular in the manner of a scan of Planck's white light curve with simultaneous Measurement of total light output can be measured.
  • Such a measurement thus determines, on the one hand, the minimum total light output within the color loci to be removed and the dependence of the total light output on the color locus.
  • the calibration factor for reducing the intensities of the individual LED paths in terms of PWM dimming can be performed.
  • the calibration is generated by a reduction in the duty cycle of a PWM drive.
  • this can also be done by adjusting the amplitude (in the sense of amplitude dimming).
  • the calibration can be done on an adjustment of the amplitude.
  • the said intensity scan can be carried out repeatedly, since the different LEDs with regard to their efficiency (intensity per stream) have different aging phenomena that must be compensated and can lead to different efficiencies.
  • a dye-converted LED will have a higher degree of aging than monochromatic LEDs.
  • said intensity scan can also be used for monitoring the aging when the operating data of the LED are known (for example stored in the memory 4 of the LED module F).
  • aging parameters can already be determined by the manufacturer and, for example, stored in the memory 4, which is assigned to the LED module F.
