DRIVER UNIT AND DRIVING METHOD FOR DRIVING A LOAD

摘要

The present invention relates to a driver unit (18) for driving a load including a plurality of load elements (12), in particular a plurality of lighting elements (12) including one or more LEDs (16). The driver unit comprises a plurality of driver devices (20) connected to the load elements for driving the load elements individually. The driver unit comprises a control interface (22) for receiving a power control signal (24) including a single general power demand to be set by the driver unit. Each driver device comprises a driver interface (26) connected to the control interface for receiving the power control signal including the single general power demand, and each driver device is adapted to determine an individual power level on the basis of the single general power demand and to drive the load elements according to the individual power signal.
