Abstract
A lamp for internal lighting of an electric household appliance includes an LED, a printed circuit for supporting and powering the LED, and a supporting body made of an electrically non-conductive material and provided, at a first end thereof, with a reflecting/diffusing element for light emitted from the LED. The LED is carried on a flat face of the printed circuit, at a first end of the printed circuit. The supporting body has a tubular shape and the printed circuit being supported inside the supporting body, with the flat face arranged substantially coplanar with an optical axis of the reflecting/diffusing element and the first end of the printed circuit overhangingly protruding from the first end of the supporting body, so that the reflecting/diffusing element collects at least a part of the light emitted from the LED. The printed circuit extends over an entire length of the supporting body.
