Abstract
Device for preventing the formation of rings and blackening at the ends of fluorescent lamps, characterized in that it essentially consists of two corrugated metal ribbons, in order to have a larger collecting surface and to provide them with a great power of retention and fixity of the carbon, have been previously treated by projecting on them by means of an aerographic system with molten aluminum in an inert atmosphere, with which they remain aluminized, presenting a rough and very porous appearance.
