Figur 1 zeigt eine dreidimensionale Ansicht einer erfindungsgemäßen Hausgerätvorrichtung, welche eine Lichtemissionseinheit 10 und eine Trägereinheit 12 aufweist. Die Trägereinheit 12 nimmt eine gesamte Gewichtskraft der Lichtemissionseinheit 10 auf. Ferner ist die Trägereinheit 12 an die Lichtemissionseinheit 10 durch Spritzgießen angespritzt.

Auf das Elektrolumineszenz-Lichtemissionsmittel 14 sind elektrische Kontaktflächen 28 aufgedruckt, welche als Metallflächen ausgebildet sind. Das Elektrolumineszenz-Lichtemissionsmittel 14 ist teilweise aus Polycarbonat gebildet.
