Modular installation and conversion kit for electronic sign structure and method of using same

A modification kit for sign conversion, comprising:

• a plurality of display modules for converting electrical data into visible radiant energy for display by an electronic sign;
• at least one compound structural frame for defining a plurality of structural bay members, each individual one of said plurality of structural bay members being configured for removably receiving, supporting and latching therein corresponding ones of said plurality of display modules each being mounted with a sufficient latching force to withstand a wind load force in excess of 100 pounds per square foot;
• wherein each individual one of said plurality of structural bay members has a sufficient number of cutout areas to provide a frame weight of no greater than 50 pounds for hand lifting and mounting the compound structural frame to a planar structural surface by a single person, but not such a sufficient number of cutout areas to compromise the structural integrity of the compound structural frame for resisting wind load forces of up to 100 pounds per square foot when mounted to the planar structural surface while supporting said plurality of display modules;
• and
• at least one preformed interchangeable wiring harness having a plurality of mechanical-electrical nodes for coupling a source of low voltage power from a backside to a frontside of the planar structural surface and then to said plurality of display modules.

A self contained in-field retrofit kit for a static billboard coupled to a universal source of electrical power, comprising:

• at least one modular hand mountable compound structural frame for mounting to at least one poster panel of a static billboard, said at least one modular compound structural frame and said at least one poster panel cooperating to provide a plurality of self cooling vents and a plurality of wire routing paths between said at least one modular compound structural frame and the universal source of electrical power;
• wherein said at least one modular compound structural frame is provided with a plurality of receptacle nodes and wire routing guides to receive substantially identical power and data wire harnesses for coupling electrical energy along a plurality of wire routing paths within said modular compound structural frame;
• at least one modular electrical conversion device for mounting partially within an individual one of said plurality of self cooling vents and partially within said at least one modular compound structural frame, said at least one modular electrical conversion device for coupling to the universal source of electrical power via at least an individual one of said plurality of wire routing paths to transform the universal source of power to a constant power source;
• wherein said at least one modular electrical conversion device includes a plurality of electrical elements coupled to said constant power source and to a data source for converting electrical energy into visible radiant energy indicative of an electronic message intended for public viewing;
• and
• wherein said at least one modular electrical conversion device is further for coupling to the data source via said at least an individual one of said plurality of wire routing paths.
