Abstract

A normal lighting circuit 2 includes a trigger device 6 which is actuated in response to a failure in the power supply to the normal lighting circuit 2. The trigger device 6 triggers an emergency lighting system 14, bypassing at least one switch 12 in the emergency lighting system 14, and the emergency lighting 14 is illuminated regardless of whether the switch 12 is opened or closed. A second trigger device 30 may be included in the emergency lighting system 14 so that in the event of a failure in the power supply to the emergency lighting circuit 14, a switch 4 in the normal lighting circuit 2 is bypassed.
