A method of manufacturing support elements for lighting devices includes: providing an elongated, electrically non-conductive substrate with opposed surfaces, with an electrically-conductive layer extending along one of said opposed surfaces, etching said electrically-conductive layer to provide a set of electrically-conductive tracks extending along the non-conductive substrate with at least one portion of the non-conductive substrate left free by the set of electrically-conductive tracks, forming a network of electrically-conductive lines coupleable with at least one light radiation source at said portion of said non-conductive substrate left free by the electrically-conductive tracks. Said forming operation includes selectively removing e.g. via laser etching a further electrically-conductive layer provided on said non-conductive substrate, or printing electrically-conductive material onto the non-conductive substrate. The electrically-conductive tracks and the network of electrically-conductive lines may be coupled with each other e.g. by means of electrically-conductive vias extending through the non-conductive substrate.
