  • an inner compartment including a tub generally housing a rotatable drum
  • a user e.g ., through a proper access door and/or lid
  • a lighting apparatus which substantially comprises one or more light sources - incandescent light lamps, fluorescent light lamps, discharge light lamps or solid-state lighting devices (e.g., high power LEDs) - acting as corresponding light sources for illuminating the drum, and a supply electric assembly - including electronic circuitry, such as rectifiers and controllers, and electrical wires - for generally supplying an operative electric power (from a power source of the machine) to each light source for the energization thereof.

  • the lighting apparatus may be arranged inside the drum (e.g., in drum walls and/or in lifters inside the drum).
  • the Applicant has recognized that the approach providing the light source within the drum is intrinsically difficult to implement - substantially due to the fact that the light source, which is arranged on a portion of the machine ( i.e. , the drum) adapted to rotate with respect to the casing of the machine, has to be electrically connected with the supply electric assembly, which is instead stationary with respect to the casing.
  • the supply electric assembly which is instead stationary with respect to the casing.

  • the stationary element may be adapted to electrically couple with the light-emitting element by means of a physical contact.
