マスタユニット及びスレーブユニットを含む照明システムであって、マスタユニットはスレーブユニットがマスタを引き継いだ状態でスリープモードに移行することができる、照明システム

摘要

The invention relates to a system comprising a main electrical unit (2) and a peripheral electrical unit (3, 4,5), wherein the main electrical unit and the peripheral electrical unit are switchable between a low-power mode and a high-power mode. The main electrical unit is adapted to hand over a control of the system to the peripheral electrical unit, if the peripheral electrical unit is in the high-power mode, and to switch from the high-power mode to the low-power mode, after the control has been handed over. The peripheral electrical unit is adapted to receive the control from the main electrical unit and to control the system, if the peripheral electrical unit is in the high-power mode. This allows the system to be still in operation mode, although the main electrical unit has been switched to the low-power mode, thereby reducing the power consumption of the system.
