Abstract
The invention relates to a drive unit for a lighting element and an operating method for such drive unit and to a lighting element including such drive unit. By selectively providing power to a control unit of the drive unit using different voltages at different stages of the overall drive unit, there is an additional degree of freedom which may be used for improving power efficiency, in particular for reducing standby power consumption, while still meeting specific space and cost constraints.
