| 摘要 |
The invention relates to a power distribution system (1), especially a Power-over-Ethernet system, comprising at least one dominant sensor, which may be located within a powered device (4) like a lighting device, and at least one non-dominant sensor, which may be located within another powered device (4), wherein the power distribution system is adapted such that in a system low power mode the at least one dominant sensor (6) consumes power provided by a power providing unit (3) and the at least one non-dominant sensor (6) does not consume the provided power and that the power distribution system (1) switches from the system low powermode to a system high power mode, if the at least one dominant sensor (6) has sensed an event. Since in the system low power mode the at least one non-dominant sensor does not consume power, the power consumption can be reduced. |
