Definitions

  • the invention relates to a luminaire for a fluorescent lamp, which consists of a support, a ballast arranged in the support, electrical connection parts and at least one cover protecting the electrical connection parts, the support and cover being made of plastic.
  • a metal plate is arranged on the carrier to dissipate or distribute the heat emitted by the ballast.
  • Such a lamp is known for example from DE-A 1 489390.
  • the metal plate used to dissipate the heat loss is arranged entirely within the carrier.
  • the carrier In order to be able to carry the considerable weight of the ballast, the carrier must have a high stability and consequently a relatively thick wall, so that overall the heat dissipation is severely impaired due to the low thermal conductivity of the plastic carrier.
  • the luminaire also does not meet the requirements of protection class 11 of the VDE guidelines.
  • a luminaire according to DE-A 2 853 854 which has a metallic carrier profile, on the end faces of which sockets with the electrical connecting lines are arranged.
  • a ballast is arranged in the carrier profile, which is surrounded on all sides by an insulation layer in order to meet certain protection regulations (protection class 11 of the VDE guidelines).
  • the invention has for its object to provide a luminaire for fluorescent lamps with built-in ballast that meets the requirements of protection class 11 according to VDE, in which no special insulation of the ballast is required and in which good heat dissipation of the ballast is achieved, so that the luminaire can be installed particularly in living room furniture.
  • the metal plate is arranged on the outside, electrically insulated, on the side of the carrier facing away from the ballast, the region of the carrier being arranged between the metal plate and ballast is made as thin as possible a plastic layer.
  • This metal plate is either fastened directly on the side of the carrier facing away from the ballast or in a recess therein.
  • the type of fastening of the metal plate to the carrier can be chosen as desired.
  • the metal plate can be screwed, riveted, glued, etc. and / or the recess is provided with an undercut so that the plate is clamped.
  • the metal plate is molded in during the manufacture of the carrier, for example overmolded, which saves the additional operations mentioned above for fastening the metal plate.
  • the distance between the ballast and the metal plate should be as small as possible, i.e. the plastic layer should be as thin as possible to ensure good heat transfer.
  • the lamp 1 shown is equipped with a slim, single-ended, compact fluorescent lamp 2.
  • the lamp 1 consists of three housing parts: a carrier 3, which receives the ballast 4 and the electrical connection parts 5a-d, a cover 6 for the electrical connection parts 5a-d and a hood 7 above the lamp 2, which scatters the emitted light and optically resolves the two legs of the lamp 2. All three housing parts are made of plastic.
  • the electrical connection parts 5a-d of the lamp 1 consist of a holder 5a, electrical lines 5b, a switch 5c and a connecting cable 5d, which in the case of a lamp for fixed connection (not shown) is connected directly to the electrical power supply or in the case of a “mobile” lamp 1, for example for connecting to a shelf by means of separate fastening elements, is provided with a plug 8.
  • a metal plate 9 in this case made of aluminum, is provided on the carrier 3 on the side facing away from the pre-folding device 4.
  • the metal plate 9 is arranged sunk on the carrier 3 and fastened to it by means of knobs 10 formed on the carrier 3 and deformed by heat or ultrasound after the metal plate 9 has been placed on it.
