摘要： An improved control circuit arrangement and control method is described for supplying power to, and for controlling, light-emitting diodes used for illuminating. The control circuit arrangement includes a driver circuit capable of operating in multiple modes for providing an operating current for operating at least one light-emitting diode, wherein the operating current has different positive intensities. In particular, the present control circuit arrangement and control method now deliberately exploit the fact that the color spectrum of a light emitting diode is dependent on the intensity or current with which it is operated, and improves the color rendering index by deliberately operating the light emitting diodes with different intensities over time.

摘要： An operating circuit is provided for an LED, which receives a voltage, and which supplies a voltage for the LED via a coil, having a first switch clocked by a control/regulating unit. Power is stored temporarily in the coil when the first switch is activated so that the power is discharged via a diode and via the LED when the first switch is turned off. A capacitor is arranged in parallel to the LED and maintains current through the LED during the demagnetization of the coil. A first switch generates a first sensor signal dependent on the current flowing through the first switch, and/or a second sensor unit, which detects whether demagnetization of the coil unit has occurred and generates a sensor signal. The signals are fed to the control/regulating unit and processed. The control/regulating unit reactivates the first switch when the coil is demagnetized and/or the diode is blocking.
