摘要:
A support structure (10) for lighting devices, e.g. LED lighting devices (M), includes: - an electrically insulating core layer (12) having a first (12a) and a second (12b) mutually opposed surfaces, with mounting locations (M) for electrically-powered light radiation sources (L) on the first surface (12a), - a network of electrically conductive lines (14) printed on said first surface (12a), at least some of said electrically conductive lines (14) extending between the mounting locations (M) and fixed locations (16) on the first surface (12a), and - electrical distribution lines (18) of electrically conductive material on the second surface (12b) of the core layer (12), and - electrically conductive vias (20) extending through core layer (12) and electrically coupling the electrical distribution lines (12) on the second surface (12b) with the electrically conductive lines (14) at said fixed locations (16) on the first surface (12a).
