ABSTRACT:
A thin film electroluminescent (TFEL) device for producing multiple light sources. The device is comprised by a TFEL flat panel structure containing light energy generating material and having front and rear faces and side edges extending between the faces. The panel structure is composed of a face emitter portion and an edge emitter portion. The face emitter portion is operable for emitting light energy from one of the front and rear faces of the flat panel structure in a direction substantially perpendicular to the plane of the flat panel structure. The edge emitter portion is operable for emitting light energy from one of the side edges of the flat panel structure in a direction substantially parallel to the plane of the flat panel structure.
