| 摘要 |
The invention relates to a driver circuit arrangement ( 1 ') for driving a plurality of individually switchable electrical subsystems (A', B', C'), such as (arrangements of) LEDs ( 9 -A, 9 -B, 9 -C). Each subsystem has at least one energy storage device ( 10 -A, 10 -B, 10 -C), such that when the subsystem is disconnected from the main source ( 7 ) of electrical energy, the energy storage device can supply energy to the device(s) of the subsystem. By furthermore providing at least one subswitch ( 13 -A, 13 -B, 13 -C) in the subsystem, between the energy storage device and an electrical device of the subsystem, control over the device is still possible when the subsystem is disconnected form the main source of electrical energy.
