  • Lamps typically comprise a fitting portion configured for being connected to an external source of electric power; a control module mounted on the fitting portion and configured for receiving electric power from the latter; and a lighting portion mounted on the control module and electrically connected to the latter in such a way as to be able to provide a luminous emission.
  • the lighting portion comprises a hollow body made of transparent or semi- transparent material.
  • LED lamps are specifically concerned, they typically have a heavy structure that is also difficult to dispose of.
  • such lamps are expensive to manufacture because of the materials employed, and the production process normally implies that such lamps are difficult to disassemble and store when the disposal process requires such operations; therefore, such lamps are hardly recyclable.
