    摘要: The invention relates to an operating circuit for at least one LED, said operating circuit being supplied with DC voltage or with rectified alternating voltage and providing a supply voltage for at least one LED by means of a coil (L1) and a first switch (S1) clocked by a control/regulation unit (SR). When the first switch (S1) is activated energy is temporarily stored in the coil (L1) and when the first switch (S1) is deactivated said energy is discharged via a diode (D1) and via at least one LED. The control/regulation unit (SR) activates the first switch (S1) when a reactivation condition has been met, and the control/regulation unit (SR) deactivates the first switch (S1) when a deactivation condition has been met. Said reactivation condition and/or deactivation condition can be set in accordance with the current dimming level.
