Support structure for lighting devices, corresponding lighting device and method

A lighting device, including:

• a support structure, wherein the support structure includes
• an electrically insulating core layer having first and second opposed surfaces, with mounting locations for electrically-powered light radiation sources on said first surface,
• a network of an electrically conductive lines printed on said first surface, said network including electrically conductive lines extending between at least some of said mounting locations and fixed locations on said first surface,
• electrical distribution lines of electrically conductive material on said second surface of the core layer, and
• electrically conductive vias extending through said core layer, said conductive vias electrically coupling said electrical distribution lines on said second surface with said network of electrically conductive lines at said fixed locations on said first surface;
• and
• electrically-powered light radiation sources, mounted at said mounting locations on said first surface.

A method of providing a support structure for lighting devices, the method including:

• providing an electrically insulating core layer having first and second opposed surfaces, with mounting locations for electrically-powered light radiation sources on said first surface,
• printing on said first surface, a network of an electrically conductive lines, said network including electrically conductive lines extending between at least some of said mounting locations and fixed locations on said first surface,
• providing electrical distribution lines of electrically conductive material on said second surface of the core layer, and
• providing electrically conductive vias extending through said core layer, said conductive vias electrically coupling said electrical distribution lines on said second surface with said network of electrically conductive lines at said fixed locations on said first surface.
