A graphic display device illuminates interchangeable graphic panels and is mountable to a translucent mounting surface. The graphic display device includes a housing assembly, a light source assembly, a light guide assembly, and device-to-surface mounts. The housing assembly includes a housing back, a housing front, and peripheral housing edging. Together, the housing back and housing edging define a panel-receiving volume. The light source assembly includes a power source, a light source, and circuitry. A light guide of the light guide assembly is positionable within the panel-receiving volume for guiding light from the light source in an anterior direction. The device-to-surface mounts fasten the graphic display device to a translucent mounting surface, and are cooperably associated with the peripheral housing edging for supporting the housing assembly such that the light from the light source is guided in an anterior direction through the translucent mounting surface. |

1. A graphic display device for illuminating interchangeable graphic panels, the graphic display device comprising:
a housing assembly, the housing assembly comprising a housing top, a housing bottom, laterally opposed housing sides, a housing back, a housing front, and a substantially circular peripheral housing edging, the housing back comprising an assembly-receiving cavity and laterally opposed, posteriorly extending, retainer-engaging projections, the peripheral housing edging defining a panel-receiving volume in anterior adjacency to the assembly-receiving cavity; a light source assembly, the light source assembly comprising, in electrical communication: a power source, a light source, and circuitry, the power source and circuitry being receivable in the assembly-receiving cavity, the light source being received radially adjacent the peripheral housing edging; a light guide assembly, the light guide being positionable in anterior adjacency to the power source in edge adjacency to the light source for guiding light from the light source in an anterior direction orthogonal to a light guide plane of the light guide; and laterally opposed device-to-surface retainer structures for fastening the graphic display device to a mounting surface, the device-to-surface retainer structures each comprising an anterior retainer portion, a posterior retainer portion, and an edge-receiving void intermediate the anterior and posterior retainer portions, the edge-receiving voids for binding to laterally opposed portions of the peripheral housing edging, the anterior retainer portions each having an anterior portion length, the posterior retainer portions each having a posterior portion length and an upper rearward portion, the upper rearward portions for supporting the housing assembly via the posteriorly extending, retainer-engaging projections, the posterior portion lengths being abbreviated relative to the anterior portion lengths for enhancing stability of the housing assembly as supported by the device-to-surface retainer structures, the device-to-surface retainer structures for supporting the housing assembly such that the light from the light source is guided in the anterior direction, the anterior direction being orthogonal to the mounting surface. |
