  • the mounting bracket is designed so that it not only takes over the attachment of the lamp unit and the dimensional stability of the elongated housing, but at the same time causes a heat conduction from the lamp to the cross connection.
  • the mounting bracket is made of sheet metal for this purpose and thus transfers the heat to the cross connection. Made of a metal, e.g. Steel-made cross-connection then releases the heat generated by the bulbs to the environment. Since the cross-connection plate itself is used as a heat sink, overheating is ruled out despite the very low overall height, with the use of LEDs in particular reducing the dissipated heat anyway.
  • the position and arrangement of the LEDs was chosen so that the most uniform possible and in all drawers sufficiently strong illumination or lighting of the frozen goods was achieved.
  • the inventive arrangement of the lamp unit on the middle cross-connection of the fridge / freezer combination thus allows a simple illumination of the freezer, which can be used in particular in built-in appliances. It is also conceivable, especially for built-in appliances without control panel such.
