Abstract

Es wird eine Innenraumbeleuchtung für Hausgeräte, vorzugsweise Kühl- und Gefrierschränke vorgeschlagen, bei welcher als Leuchtmittel eine oder mehrere Leuchtdioden (5) vorgesehen sind, die parallel und/oder in Reihe miteinander verschaltet und mittels eines elektronischen Schalters, vorzugsweise eines Transistors (11), schaltbar sind. Vorzugsweise werden weißes Licht abstrahlende Lumineszenskonversions-Dioden oder solche Leuchtdioden verwendet, die verschiedenfarbiges, vorzugsweise gelbes und blaues oder rotes, grünes und blaues Licht abstrahlen, wobei durch die Überlagerung der verschiedenen Farben weißes Licht entsteht.

Figure 00000001
Interior lighting for domestic appliances, preferably refrigerators and freezers, is proposed, in which one or more light-emitting diodes (5) are provided as the illuminant, which are connected in parallel and / or in series and by means of an electronic switch, preferably a transistor (11), are switchable. Luminescence conversion diodes which emit white light or those light-emitting diodes which emit differently colored, preferably yellow and blue or red, green and blue, light are preferably used, white light being produced by the superimposition of the different colors.
