Abstract: A sign plate for an edge-illuminated sign including a transparent sheet with a front face, a rear face and a transparent edge that connects the front face to the rear face, wherein the transparent edge is positioned to receive light from a light source for transmission along the transparent sheet. The sign plate further includes a front image layer disposed on a front face of the transparent sheet, wherein the front image layer has a reflective surface. A rear image layer is disposed on a rear face of the transparent sheet substantially in registry with the front image layer, wherein the front image layer and the rear image layer are positioned so that the light within the transparent sheet is reflected from the reflective surface onto the rear image layer thereby to enhance illumination of the rear image layer. The sign plate has a structure such that a portion of the light within the transparent sheet forms an image of a halo or aura of light surrounding the rear image layer.

Abstract: A sign plate for an illuminated sign having a light source includes an opaque reflective layer on its face that receives light from the light source. The opaque reflective layer is broken by zones corresponding to a configuration of text, figures, and/or art design to be communicated to a viewer. The zones are covered with a light diffusion layer on the side of the light source, and the surface of the sign plate facing the viewer and opposite the light source includes a layer of reflective material in a corresponding configuration that is in general register with the configuration defined by the zones and covered by the light diffusion layer on the side of the light source.
