Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • the interior lighting can be done in different colors, however preferably white light is used.
  • 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.
  • 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.
  • the LEDs are at least over part of the interior of the household appliance distributed, resulting in a uniform illumination of this Interior results.
  • 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.
  • LEDs 5 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.
  • 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.
  • 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.
