Description

Die Neuerung betrifft eine Innenraumbeleuchtung für Hausgeräte, vorzugsweise Kühl- und Gefrierschränke sowie Waschmaschinen und Wäschetrockner, welche durch das Öffnen einer Tür oder durch Betätigung eines Handschalters eingeschaltet wird.The innovation relates to interior lighting for household appliances, preferably Fridges and freezers as well as washing machines and tumble dryers, which switched on by opening a door or by operating a hand switch becomes.

Als Leuchtmittel für derartige Innenraumbeleuchtungen werden nach Stand der Technik Glüh- bzw. Halogenbirnen verwendet. Diese besitzen eine relativ hohe Leistungsaufnahme (5 bis 25 Watt) und eine hohe Verlustleistung. So geben sie zirka 95 bis 97% der aufgenommenen Leistung als Wärme und nur den Rest in Form von Licht ab. Diese Wärmeabgabe bedeutet besonders bei Kühl- und Gefrierschränken eine zusätzliche, unerwünschte Wärmezufuhr in den Kühlraum, die vom Kühlaggregat verarbeitet werden muß. Zudem ist die Lebensdauer dieser Leuchtmittel, auch durch die häufigen Einschaltvorgänge, mit weniger als 1.000 Stunden recht gering. Die Leuchtmittel müssen daher bei einem Defekt austauschbar sein, wobei der geforderte Berührungsschutz gewährt sein muß. Darüber hinaus ist ein Explosionsschutz bei Verwendung von explosionsgefährdeten Kühlmitteln nur bei gekapselten Birnenfassungen, Kontakten und Schaltern gegeben.As illuminants for such interior lighting are according to the state of the Technology light bulbs or halogen bulbs used. These are relatively high Power consumption (5 to 25 watts) and high power loss. So they give about 95 to 97% of the power consumed as heat and only the rest in Form of light. This heat release means especially in refrigerators and freezers an additional, undesirable heat supply in the refrigerator, which from Cooling unit must be processed. In addition, the lifespan of this Illuminants, also due to the frequent switch-on processes, with less than 1,000 Hours quite low. The lamps must therefore be replaced if they are defective be, whereby the required protection against contact must be granted. Furthermore is an explosion protection when using explosive coolants only available with encapsulated bulb sockets, contacts and switches.

Ausgehend von diesem Stand der Technik liegt der Neuerung die Aufgabe zugrunde, eine Innenraumbeleuchtung für Hausgeräte zu schaffen, welche die genannten Nachteile nicht besitzt und trotzdem eine ausreichende Ausleuchtung des Hausgeräte-Innenraums bietet.Based on this state of the art, the innovation is based on the task to provide interior lighting for home appliances, which the above Does not have disadvantages and nevertheless sufficient lighting of the interior of the household appliances offers.

Diese Aufgabe wird durch eine Innenraumbeleuchtung für Hausgeräte mit den Merkmalen des Schutzanspruches 1 erfüllt. Ausführungsformen und Weiterbildungen der Neuerung sind in den Unteransprüchen beschrieben. This task is achieved by indoor lighting for household appliances Features of protection claim 1 fulfilled. Embodiments and further developments the innovation are described in the subclaims.

Bisher konnten zur Ausleuchtung eines Hausgeräte-Innenraumes Leuchtdioden nicht verwendet werden, da sie zum einen nicht hell genug strahlten und da vor allem keine blaues Licht abstrahlende Halbleiter-Dioden erhältlich waren, wodurch erst die Erzeugung von weißem Licht mittels Überlagerung mit anderen Farben möglich wurde.So far, LEDs have been used to illuminate the interior of a domestic appliance not be used because on the one hand they did not shine brightly enough and there all no blue light emitting semiconductor diodes were available, which only the generation of white light by overlaying it with other colors became possible.

Durch die Verwendung von Leuchtdioden als Leuchtmittel für die Hausgeräte-Innenraumbeleuchtung werden die oben genannten Nachteile vermieden. Leuchtdioden haben eine sehr geringe Leistungsaufnahme (0,01 bis 0,1 Watt), weshalb auch bei Verwendung mehrerer bzw. zahlreicher Leuchtdioden der Energieverbrauch gegenüber herkömmlichen Glühbirnen deutlich verringert wird. Der bessere Wirkungsgrad der Leuchtdiode (ca. 20% gegenüber 5% für die Glühbirne) bedingt eine deutlich geringere Wärmeabgabe durch Verlustleistung, wodurch eine unnötige und bei Kühl- und Gefrierschränken unerwünschte Erwärmung des beleuchteten Innenraums des Hausgeräts praktisch ganz vermieden wird. Zudem haben Leuchtdioden mit 100.000 Stunden eine sehr hohe Lebensdauer, weshalb sie während des Lebenszyklus eines Hausgeräts nicht ausgewechselt werden müssen und der dafür notwendige Kundendienst-Aufwand entfällt.Through the use of light-emitting diodes as illuminants for domestic appliance interior lighting the disadvantages mentioned above are avoided. LEDs have a very low power consumption (0.01 to 0.1 watts), which is why energy consumption when using multiple or numerous LEDs compared to conventional light bulbs. The better efficiency the light-emitting diode (approx. 20% versus 5% for the light bulb) a significantly lower heat dissipation through power loss, which makes an unnecessary and undesirable heating of the illuminated in refrigerators and freezers Interior of the home appliance is practically avoided entirely. In addition, LEDs have with 100,000 hours a very long service life, which is why during the Life cycle of a home appliance does not need to be replaced and the one for it necessary customer service effort is eliminated.

Um die Leuchtstärke einer Glühbirne zu erreichen, sind mehrere Leuchtdioden nötig, welche zumindest teilweise parallel und/oder in Reihe miteinander verschaltet sind. Das Ein- und Ausschalten der Beleuchtung erfolgt mittels eines elektronischen Schalters, vorzugsweise eines Transistors. Dadurch kann bei Kühl- und Gefrierschränken ein einfacher Explosionsschutz erreicht werden und auch bei Verwendung von explosionsgefährdeten Kühlmitteln ein einwandiger Verdampfer im Kühlkreislauf eingesetzt werden.To achieve the luminosity of a light bulb, there are several light emitting diodes necessary, which interconnects at least partially in parallel and / or in series are. The lighting is switched on and off by means of an electronic one Switch, preferably a transistor. This can be used in refrigerators and freezers simple explosion protection can be achieved and also when used of explosion-prone coolants is a single-walled evaporator in the Cooling circuit can be used.

Die Innenraumbeleuchtung kann in verschiedenen Farben erfolgen, wobei jedoch vorzugsweise weißes Licht verwendet wird. In einer Ausführungsform werden dazu weißes Licht abstrahlende Lumineszenskonversions-Dioden verwendet. Bei diesen wird ein Teil des von einer Halbleiter-Diode erzeugten blauen Lichts in gelbes Licht umgewandelt, wobei durch die Überlagerung dieser beiden Farben weißes Licht entsteht. In einer anderen Ausführungsform werden Leuchtdioden verwendet, welche verschiedenfarbiges Licht erzeugende Halbleiter-Dioden aufweisen, wobei durch die Überlagerung der verschiedenen Farben (vorzugsweise gelb und blau oder auch rot, grün und blau) weißes Licht entsteht.The interior lighting can be done in different colors, however preferably white light is used. In one embodiment luminescence conversion diodes that emit white light are used for this. At this turns part of the blue light generated by a semiconductor diode into yellow Light is converted to white by the overlay of these two colors Light is created. In another embodiment, light-emitting diodes are used which have different-colored light-producing semiconductor diodes, with the overlay of different colors (preferably yellow and blue or red, green and blue) white light is created.

In Weiterbildung sind die Leuchtdioden zumindest über einen Teil des Innenraumes des Haushaltsgeräts verteilt, wodurch sich eine gleichmäßige Ausleuchtung dieses Innenraums ergibt.In a further development, the LEDs are at least over part of the interior of the household appliance distributed, resulting in a uniform illumination of this Interior results.

Eine Ausführungsform der Neuerung als Kühlschrankbeleuchtung soll im folgenden anhand der Abbildungen näher erläutert werden. Es zeigen:

Figur 1
einen geöffneten Kühlschrank mit Innenraumbeleuchtung und
Figur 2
eine Schaltungsanordnung für die Leuchtdioden der Innenraumbeleuchtung.
An embodiment of the innovation as refrigerator lighting will be explained in more detail below with the aid of the figures. Show it:
Figure 1
an open refrigerator with interior lighting and
Figure 2
a circuit arrangement for the light emitting diodes of the interior lighting.

Gemäß der Neuerung weist ein Kühlschrank 1 an den Innenflächen seiner Seitenwände 2, Rückwand 3 und Decke 4 eine Vielzahl von weißes Licht abstrahlenden Lumineszenskonversions-Leuchtdioden 5 auf. Die Leuchtdioden sind gleichmäßig über die Innenflächen des Kühlschranks 1 verteilt, wodurch sich eine sehr gleichmäßige Ausleuchtung des Kühlschrankinnenraumes ergibt. Die Tür 6 des Kühlschranks 1 schließt mit Hilfe von Magnetkontakten 7 und 8.According to the innovation, a refrigerator 1 has on the inner surfaces of its side walls 2, back wall 3 and ceiling 4 emit a variety of white light Luminescence conversion LEDs 5. The LEDs are even distributed over the inner surfaces of the refrigerator 1, which results in a very uniform Illumination of the refrigerator interior results. The door 6 of the refrigerator 1 closes with the help of magnetic contacts 7 and 8.

Statt der Verwendung einzelner Leuchtdioden 5 können auch jeweils mehrere Leuchtdioden 5 zu Leuchtdioden-Gruppen zusammengeschlossen und mehrere solche Leuchtdioden-Gruppen über die Innenflächen des Kühlschranks verteilt sein.Instead of using individual light emitting diodes 5, several can also be used LEDs 5 combined into LED groups and several such light emitting diode groups can be distributed over the inner surfaces of the refrigerator.

Wie in Figur 2 ersichtlich ist zu jeder Leuchtdiode 5 eine Zener-Diode 9 parallel und in Sperrichtung geschaltet. Dies dient der Überbrückung der jeweiligen Leuchtdiode 5, falls diese einmal ausfallen sollte.As can be seen in FIG. 2, a Zener diode 9 is parallel to each light-emitting diode 5 and switched in the reverse direction. This serves to bridge the respective LED 5, should this ever fail.

Jeweils drei Leuchtdioden 5 sind mit einem Vorwiderstand R zu einem Leuchtdiodenzweig 10 hintereinander geschaltet. Mehrere solche Leuchtdiodenzweige 10, von denen in Figur 2 nicht alle gezeichnet sind, sind miteinander parallel verschaltet, mit ihrem Pluspol an die positive Betriebsspannung UB und mit ihrem Minuspol über einen Transistor 11 mit Erde verbunden. In each case three light emitting diodes 5 are connected in series with a series resistor R to form a light emitting diode branch 10. Several such light-emitting diode branches 10, not all of which are shown in FIG. 2, are connected in parallel with one another, with their positive pole connected to the positive operating voltage U B and with their negative pole connected to earth via a transistor 11.

Diese Verschaltung der Leuchtdioden in Fig. 2 ist nur beispielhaft aufgeführt. Im Rahmen der Neuerung sind zahlreiche, davon abweichende Verschaltungen möglich, wie etwa die Hintereinanderschaltung von mehr oder auch weniger als drei Leuchtdioden 5 zu einem Leuchtdiodenzweig 10 oder die Parallelschaltung von je einer Zener-Diode 9 mit mehreren Leuchtdioden 5, die ihrerseits wieder parallel oder seriell miteinander verschaltet sein können.This connection of the light emitting diodes in FIG. 2 is only given as an example. in the As part of the innovation, numerous, different interconnections are possible, such as connecting more or less than three in series LEDs 5 to a light emitting diode branch 10 or the parallel connection of each a Zener diode 9 with a plurality of light-emitting diodes 5, which in turn are parallel again or can be connected in series.

Beim Öffnen der Tür 6 des Kühlschranks 1 werden die Magnetkontakte 7 und 8 getrennt, wodurch eine Schaltspannung + US über Widerstand R an die Basis des Transistors 11 angelegt wird. Dadurch wird der Transistor 11 durchgeschaltet und die Innenraumbeleuchtung eingeschaltet.When the door 6 of the refrigerator 1 is opened, the magnetic contacts 7 and 8 are disconnected, as a result of which a switching voltage + U S is applied to the base of the transistor 11 via the resistor R. As a result, the transistor 11 is switched on and the interior lighting is switched on.

Sollte eine der Leuchtdioden 5 ausfallen, bricht die entsprechende Zener-Diode 9 aufgrund der jetzt hohen an ihr anliegenden Spannung durch, wodurch die ausgefallene Leuchtdiode überbrückt wird und ein Betrieb der restlichen Leuchtdioden 5 des entsprechenden Leuchtdiodenzweiges möglich bleibt. Somit bleibt die Innenbeleuchtung auch bei Ausfall einer oder einzelner Leuchtdioden 5 weiterhin und mit nur unbedeutend geringerer Helligkeit funktionsfähig.If one of the LEDs 5 fails, the corresponding Zener diode 9 breaks due to the now high voltage applied to it, which makes the failed Light-emitting diode is bridged and operation of the remaining light-emitting diodes 5 of the corresponding LED branch remains possible. The interior lighting thus remains even with failure of one or individual LEDs 5 and with only insignificantly lower brightness functional.
