Claims (5)

1. Innenraumbeleuchtung für Hausgeräte, vorzugsweise Kühl- und Gefrier­ schränke sowie Waschmaschinen und Wäschetrockner, welche durch das Öff­ nen einer Tür oder durch Betätigung eines Handschalters eingeschaltet wird, dadurch gekennzeichnet, daß als Leuchtmittel eine oder mehrere Leuchtdioden (5) (LEDs) vorgesehen sind, welche parallel und/oder in Reihe miteinander verschaltet und mittels ei­ nes vorzugsweise elektronischen Schalters, vorzugsweise eines Transistors (11), schaltbar sind.1. Interior lighting for household appliances, preferably refrigerators and freezers as well as washing machines and tumble dryers, which is switched on by opening a door or by actuating a manual switch, characterized in that one or more light-emitting diodes ( 5 ) (LEDs) are provided as the illuminant which are connected in parallel and / or in series and can be switched by means of a preferably electronic switch, preferably a transistor ( 11 ). 2. Innenraumbeleuchtung nach Anspruch 1, dadurch gekennzeichnet, daß als Leuchtmittel weißes Licht abstrahlende Lumineszenzkonversions- Dioden verwendet werden.2. interior lighting according to claim 1, characterized, that luminescence conversion radiating white light Diodes are used. 3. Innenraumbeleuchtung nach Anspruch 1, dadurch gekennzeichnet, daß als Leuchtmittel mehrere verschiedenfarbiges, vorzugsweise gelbes und blaues oder rotes, grünes und blaues Licht abstrahlende Leuchtdioden ver­ wendet werden, wobei durch die Überlagerung der verschiedenen Farben der einzelnen Leuchtdioden weißes Licht entsteht.3. interior lighting according to claim 1, characterized, that several different colored, preferably yellow and blue or red, green and blue light emitting diodes ver be applied, whereby by the overlay of the different colors of the individual light emitting diodes produce white light. 4. Innenraumbeleuchtung nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß zu jeder Leuchtdiode (5) oder Gruppe von Leuchtdioden (5) jeweils eine Zener-Diode (9) in Sperrichtung parallel geschaltet ist.4. Interior lighting according to one of claims 1 to 3, characterized in that for each light-emitting diode ( 5 ) or group of light-emitting diodes ( 5 ) a Zener diode ( 9 ) is connected in parallel in the reverse direction. 5. Innenraumbeleuchtung nach einem der vorherigen Ansprüche, dadurch gekennzeichnet, daß die Leuchtdioden (5) über den Innenraum oder einen Teil des Innenraums des Haushaltsgeräts (1) verteilt angebracht sind und sich somit eine gleichmä­ ßige Ausleuchtung des Innenraums ergibt.5. Interior lighting according to one of the preceding claims, characterized in that the light-emitting diodes ( 5 ) are attached distributed over the interior or part of the interior of the household appliance ( 1 ) and thus there is a uniform illumination of the interior.
