EMERGENCY LIGHT BUILDING BLOCK, EMERGENCY LIGHTING SYSTEM AND EMERGENCY LIGHTING ELEMENT

摘要

An emergency light module (1) for an emergency lighting system has: • a mains connection (3) and an emergency light module output (2) for feeding emergency lights; • a charger (11); • means for determining a network status at the mains connection (3); • a DC -DC converter (8) for supplying the emergency light module output (2) with energy from a battery in an emergency mode • converter isolating relay (9a, 9b) for electrical isolation of the converter output voltage (13) from the emergency light module output (2); for electrical isolation of the mains connection (3) from the emergency light module output (2); • an electronic control (7), which monitors the mains status, controls a switchover from mains to emergency operation; • means for detecting an external emergency state as a result of an emergency operation other emergency lighting module or as a result of a fault condition of a monitored voltage at another emergency lighting module; the emergency lighting module (1) is there set up to generate a switch-on sequence when the external emergency state is detected by varying the output voltage at the emergency light module output (2), and to generate the switch-on sequence using the DC-DC converter (8).
