  • the illumination device consists of a lamp which comprises a single light bulb as the light source.
  • the device by various built-in parts in the device, such as storage trays or pull-out boxes, but also by introduced food, which act as light barriers, large parts of the device by the light emitted by the lamp is not or only inadequately achieved.
  • the incandescent lighting actually converts only a small fraction of its electrical power consumption into light output; By far the greater part of the power consumption is converted into heat, which undesirably heats the interior space and has to be dissipated.
  • the installation of the illumination device takes place from the inside of the container.
  • the inner container of the refrigerator which limits the interior space against the insulating layer in the body, is generally produced in one piece from a thermoformed plastic element.
  • the inner container In order to guide the wiring of the illumination device from the insulation layer into the interior, the inner container must be punched or milled. As a result, the inner container is no longer completely closed. Over a longer period of time, moisture can penetrate the insulation layer of the device via the sealing point.

Since there are no sealing points, the insulation of the refrigeration device remains intact longer. The life cycle of the refrigeration appliance is extended. In addition, a cleaning of the inner container is much easier. With no corners and edges and seams between different materials, the inner container is more hygienic and easier to keep clean. Soiling can be recognized at first glance and easily removed. In addition, the lighting device is no longer visible part and can be produced more cheaply.
