Emergency lighting assembly with data communication capabilities

The system (1) has emergency lamps (19, 21, 23, 24) monitored by a lamp monitoring part (32) and attached to radio frequency communication modules (33-39). One of the radio frequency communication modules transfers monitoring data of the lamps in a monitoring tuple to a central unit (13) and light-spreading units (17, 18), by transmission components (40, 40 '). The communication modules are attached to the light-spreading units. An intermediate storage (41) for actual marks (42) is provided in the communication modules. An independent claim is also included for a method for transmitting data of an emergency lighting system.
