Abstract
A path way marking and lighting system utilizes continuous electroluminescent strips of indeterminate length to provide an uninterrupted illuminated path to a target destination such as an egress exit. Powering means responsive to an activation stimulus means are provided to illuminate the electroluminescent strip. Means are provided for self diagnostic testing to carry out one or more sub-system tests to detect system operation within predetermined operating parameters and means provide an alerting indicator in response to a sub-system test detecting a system operation failure.
Claims23
