A driver is provided for driving at least two sets of solid state lighting elements. A switched capacitor power converter is provided, and a switch arrangement is used for selectively connecting a first set and a second set of solid state lighting elements in series connection at the output of the power converter or connecting the first set of solid state lighting elements at the output of the power converter without the second set of solid state lighting elements. A first duty cycle of the switched capacitor power converter and a second duty cycle control of the switch arrangement are both controlled. In this driver design, a switched capacitor power converter and a switch arrangement are independently controlled using a duty cycle approach. The switched capacitor power converter is usedto provide current control, and the switch arrangement is used to control whether the second set of lighting elements is connected to the output or not. 提供了种用于驱动至少两组固态照明元件的驱动器。提供了种开关电容器功率转换器，并且开关装置被选择性地用于在功率转换器的输出处将第组固态照明元件和第
