Abstract
An emergency lighting arrangement preferably includes plural emergency light units connected to an on-board power supply network of an aircraft, and plural emergency current sources that each include at least one capacitor. Each emergency light unit includes an emergency light emitting element and a control unit that automatically connects the capacitor of the emergency current source to the emergency light emitting element upon the failure of the on-board power supply network. Preferably, the emergency current source including the capacitor is integrated into the emergency light unit. The emergency light unit may further include normal operation light emitting elements selectively connected by the control unit to the on-board power supply network. The control unit switches between normal operation of the normal light emitting elements and charging of the capacitor, and emergency operation in which the capacitor discharges through the emergency light emitting element.
