LIGHTING SYSTEM

摘要

A lighting system containing at least one controllable first light (NL) which is connected to at least one first electricity supply (L, N) and at least one controllable emergency supply light (SL) which is connected to another electricity supply (P, N) which is separated from the first electricity supply (L, N). A control device is respectively associated with each light (NL, SL). The control devices are connected to a common bus (D1, D2). A monitoring device (5) provides the bus (D1, D2) with a control signal corresponding to the state of the first electricity supply (L, N). Said signal is evaluated by at least the control device of the emergency supply light (SL) for detection of a failure and activation of the emergency supply mode.
