Abstract
An emergency lighting system for an aircraft has photoluminescent material arranged to define an escape path to the exits. The photoluminescent material is encapsulated within a track of predetermined length for securing to the floor of the aircraft. The track comprises a one piece housing formed with a longitudinally extending slot and the photoluminescent material is provided by an insert that is a push-fit in the slot from one end of the housing. The housing is closed at both ends to seal the slot and prevent ingress of dirt or fluid. In a modification the housing is compressed with the insert in place to reduce the height of the track and optionally to provide the track with anti-slip characteristics.
