Abstract

A luminaire for installation in an electrical household appliance, e.g. a washing machine, includes, in one embodiment, two light-emitting diodes mounted on a circuit board, an elongated luminaire housing having a light exit area, which is formed by a light-permeable piece of the housing wall, in an area of a first longitudinal end of the luminaire housing, and also a light-conducting body having a light-conducting tube which extends inside the luminaire housing and which conducts, towards the light exit area, light which is given off by the light-emitting diodes. In one embodiment, a metalizing layer provided on the inner peripheral face of the light-conducting tube rests, in heat-transmitting contact with one or more conductive traces, on the upper side of the circuit board. In addition to its light-conducting function, the light-conducting tube thus fulfills a function for discharging heat from the circuit board.
