Abstract

Um blickwinkelabhängig visuell störende dunkle Bereiche und streifenförmige Schlieren in der als optischer Signalgeber (16) dienenden Lichtaustrittsfläche eines Lichtleiters (19) in der Bedienblende (12) eines Haushaltsgroßgerätes (11) zu vermeiden, weist der Lichtleiter (19) eine etwa quer zu seinem Lichtweg sich erstreckende Trennebene (25) auf, in der eine der beiden hier stumpf aufeinanderliegenden Stirnflächen (26-25-26) durch mechanische Bearbeitung oder Beschichtung lichtstreuend aufgerauht ist. Das führt zu einer flächig gleichförmigen Einstrahlung in denjenigen Teil desjenigen Teillichtleiters (19"), welcher der Trennebene (25) gegenüber als der Signalgeber (16) endet, obgleich das gegenüberliegende Ende des Lichtleiters (19) von einer im Verhältnis zur anzeigenden Querschnittsfläche sehr kleinflächigen Lichtquelle (17), vorzugsweise von einer SMD-LED, bestrahlt wird.
