Claim:
1. A modular light-emitting panel assembly, comprising: a first light guide and a second light guide, each light guide having a light input edge with a greater cross-sectional width than thickness, opposed side edges, opposed major surfaces and a pattern of light extracting elements at at least one of the major surfaces, the first light guide juxtaposed with the second light guide with one of the side edges of the first light guide abutting one of the side edges of the second light guide at a seam; and a first light source and a second light source to edge light the first light guide and the second light guide, respectively, through the light input edges thereof such that light propagates along each light guide by total internal reflection at the major surfaces thereof for extraction from the light guide by the light extracting elements; wherein the abutting side edge of the first light guide is shaped to define a convex protrusion extending between the opposed major surfaces of the first light guide and the abutting side edge of the second light guide is shaped to define a complementary concave recess extending between the opposed major surfaces of the second light guide.
