ABSTRACT:
An illuminated sign device is disclosed includes a triangular housing with pper and lower surfaces between which is coupled a back surface, a front left surface, and front right surface. A light bulb provides illumination and is positioned within the housing. A mesh and ventilation holes are integral with the upper and lower surfaces respectively for allowing heat transfer from the illumination source by convection to occur through the lower surface, within the housing, and out through the upper surface. A double glass pane within the front left and front right surface allows the sign to be protected on both sides of an at least semi-opaque sign and positions the sign within the front left and front right surfaces such that the sign is at least partially viewable from any approach angle. An access panel is removably attached to the front left and front right surfaces whereby access is obtained for the interchanging of the signs, such that upon selective activation of the illumination source the sign are at least partially illuminated.
