Abstract:
The present invention relates to a solid state lighting system comprising at least one light emitting semiconductor device, at least one driver for driving a predetermined current through the at least one light emitting semiconductor device. The lighting system furthermore comprises a first voltage supplying unit coupled to provide a first supply voltage to a first side of the at least one light emitting semiconductor device, and a second voltage supplying unit coupled to provide a second supply voltage for the at least one light emitting semiconductor device. The first and the second supply voltages are selected to optimize the voltage drop across the at least one light emitting semiconductor device.
