ABSTRACT:
A contiguous emergency exit path lighting system that includes the peripheral lighting of a hollow doorframe at an egress point using a set of electroluminescent illuminators integrally formed within or upon the doorframe, an electrical bypass doorframe to reroute wiring around doorways that are not points of egress, electroluminescent illuminator strips mountable on walls, floors, and other pathway surfaces, and flush mount exit signage on the egress door to enhance visibility in high smoke and high heat applications. An integrally formed U-shaped channel within the egress doorframe secures a transparent or translucent raceway tube that encloses the electroluminescent strips.
