Abstract
An illuminated sign for application to a support surface includes a planar back panel, an electroluminescent lamp disposed over the back panel, and a transparent front panel disposed over a side of the lamp opposite the back panel with the back and front panels being secured together in alignment to form a laminate encapsulating the lamp. Indicia defined by an illuminated portion of the lamp visible through the front panel is formed by an indicia defining member that can be separate from or part of the laminate. A fixation surface having adhesive properties is disposed along a forward surface of the sign for adhesively securing the sign to the support surface by contact with the fixation surface. A power supply for the sign includes a housing for receiving a conductor of the lamp with the housing being flush with a peripheral edge of the laminate.
