ABSTRACT:
The double-sided edge lighting-type display sign of the present invention comprises at least two illuminating light sources: two or one display signages; and a light-directing panel. Preferably, a display sign housing accommodates and supports the other elements of the present invention. Namely, the light box housing supports at least two light sources, the display signages and the light-directing panel. The light-directing panel of the present invention is at least partially light reflective and at least partially light passing. The light directing panel directs and redirects light from the included at least two edge lighting-type light source to the included display signages. The light ultimately incident on the display signages is greater than it would normally be without the light-directing panel.
