A lamp for internal lighting of an electric household appliance including at least one light source consisting of a LED, a printed circuit for supporting and powering the light source and a supporting body for the printed circuit made of an electrically non-conductive material and provided, at one first end thereof, with a reflecting/diffusing element of the light emitted by the light source and defining an optical axis arranged substantially parallel to a longitudinal axis of the supporting body; wherein the at least one light source is mounted at a first end of the printed circuit, fixed to a first flat face thereof, with a light diffusion axis thereof oriented substantially perpendicular to the first face; the printed circuit being supported inside the body, which is tubular in shape, with the first face arranged substantially coplanar with the optical axis of the reflecting/diffusing element and the first end overhangingly protruding from the first end of the supporting body, within a concavity of the reflecting/diffusing element, so that the same may collect at least part of the light emitted by the light source; the printed circuit extending over the entire length of the supporting body, to a second end of the same, opposite to the first, and being provided on at least the first face with electrically and thermally conductive tracks for powering the LED, which are exposed to a convective cooling motion of the environmental air through respective longitudinal slots made through at least one side wall of the supporting body, at a predetermined distance from the first end.
