Abstract
An emergency lighting strip provides for illumination of the floor of an emergency egress passageway during clear air conditions and also marks an escape path during conditions of limited visibility. The strip mounts two strings of narrow cone L.E.D.s in a transparent tubular housing which is mounted on the passageway wall. The marker string mounts L.E.D.s at half-inch intervals with their beam axes aimed at the middle of the passageway floor. The illuminator string mounts L.E.D.s at four-inch intervals with their beam axes angled above horizontal. A strip of the half-inch spaced L.E.D.s, with the L.E.D. beam axes perpendicular to the wall is mounted to frame and mark an exit doorway.
