Definitions

  • the invention relates to a refrigerated cabinet with a fluorescent lamp which is surrounded by an impact protection lining.
  • the fluorescent tube is generally surrounded by a panel.
  • the cladding can be both a tube made of an impact-resistant, translucent material and a metal frame with an impact-resistant, translucent cover.
  • Standard fluorescent lamps with their ballasts assigned according to VDE only develop their full luminosity at temperatures of over 20 ° C. It has been found that the luminosity of the fluorescent lamps decreases with decreasing Temperature decreases. At temperatures such as those prevailing in refrigeration units, the lamps begin to flicker. Have been as a remedy in refrigeration units Hochleistun g s fluorescent tubes used but need two ballasts, and also consume more electrical energy than standard fluorescent lamps.
  • the invention has for its object to develop a refrigerator of the type described above in which standard fluorescent tubes are used in an energy-saving manner and which is uniformly illuminated at all temperatures occurring in the refrigerator.
  • This object is achieved in that a light-permeable airtight envelope arranged at a distance from it is connected to the impact protection cladding, and the impact protection cladding and / or the envelope are tightly connected to the fluorescent lamp.
  • the interaction of the casing with the impact protection lining creates an airtight space that. represents an effective thermal insulation.
  • the fluorescent lamp is tightly connected to the double-walled cladding. The heat generated during the operation of the fluorescent lamp is retained by the thermal insulation.
  • the fluorescent tube itself is used to generate a favorable operating temperature and the subject matter of the invention makes it possible to utilize the full luminosity of standard fluorescent lamps even in refrigerated furniture.
  • the covering advantageously has a shape similar to the shape of the impact protection cladding.
  • the casing is tubular, an annular insulation space being used between the two tubes when a likewise tubular impact protection cladding is used arises.
  • other shapes for the wrapping are also conceivable.
  • the impact protection cladding in the form of a hood is placed on a metal frame, the casing also expediently surrounds the casing in a hood-like manner, although additional heat insulation of the non-covered metal frame must then be provided.
  • the covering is sealed with a commercially available moisture-proof frame.
  • the air layer between the impact protection cladding and the covering is already sufficient for thermal insulation in order to maintain the ambient temperature required for trouble-free operation on the fluorescent tube.
  • An even more effective heat insulation can be produced if necessary in that, according to a favorable embodiment of the subject matter of the invention, the space between the impact protection cladding and the covering is evacuated and / or a gas filling is provided in the space which has a lower thermal conductivity than air.
  • a fluorescent lamp 1 is provided for illuminating refrigerated furniture.
  • the fluorescent lamp is in a moisture-proof socket 2.
  • the fluorescent lamp 1 is surrounded by an impact protection cladding 3 arranged coaxially to the lamp 1.
  • a translucent, airtight envelope 4 is arranged at a distance from the impact protection covering 3, which together with the impact protection covering 3 forms an annular space around the fluorescent lamp, which is sealed airtight with a seal 5.
  • a seal 6 With a seal 6, the system fluorescent lamp / impact protection cladding / covering is tightly connected to the moisture-proof socket 2 and sealed against the outside.
  • the ring-shaped space between impact protection cladding 3 and envelope 4 forms thermal insulation for the fluorescent lamp 1.
  • the temperature required for achieving the full luminosity is generated on the lamp by the inherent heat of the fluorescent lamp 1.
  • a negative pressure can be produced in the annular space and / or a gas filling with a lower thermal conductivity than air can be provided. 7 with a spacer ring for ease of assembly is designated.
  • the wet room socket further comprises a seal 8, an adapter 9 and a sleeve 10.
  • FIG. 2 shows a modified embodiment which differs from FIG. 1 by the type of seal between the impact protection lining 3 and the casing 4.
  • the seal 11 is shaped so that it also acts as a spacer for the impact protection clothing 3.
  • the separate spacer ring can therefore be omitted.
