Definitions

  • a lamp of the type mentioned has a lamp housing in which the individual electrical components for supplying the lamp, which can either be an incandescent lamp or a fluorescent lamp, are housed.
  • These luminaire housings if they are designed to be explosion-proof in type of protection "d", flameproof enclosure, are predominantly made of metal; the transparent cover attached to this metal housing is made of glass.
  • the free volume inside the luminaire housing must not exceed 3000 cm3 be.
  • the cover part can also consist of transparent plastic. Then the area that allows the light to pass through must not be larger than 8000 cm2.
  • the object of the invention is to provide a lamp of the type mentioned, in which the lamp housing is made of plastic.
  • the filling parts can be designed as carrier parts for the electrical components, or they can serve as adapters; the filler parts are then expediently made from foamed plastic. Of course, they can also consist of metal or other materials.
  • filler, sand, quartz powder or glass balls can be used, which have the advantage that the residual space to be filled has any shape can because the sand or the quartz powder or the glass balls in their entirety do not surround a defined space, for example a quarder or the like.
  • liquids can also be filled in, which is particularly advantageous when the electrical components have to be cooled. The liquid then serves as a cooling liquid.
  • the filling parts can of course also be made of ceramic, metal, or a combination of these materials.
  • the filling parts can also be used in the cover part, e.g. as a reflector carrier. Then they serve to limit the transparent, translucent surface of the cover part to an area of less than 8000 cm2. This means that the cover part can also be produced from plastic.
  • the only figure is a sectional view through a lamp according to the invention.
  • the luminaire 10 consists of a luminaire housing 11 and a cover part 12 attached to it.
  • the luminaire housing 11 is closed by means of an end wall 13, so that the housing 11 together with the end wall 13 meets the requirements of "pressure-resistant encapsulation".
  • Electrical components 14 and 15 are located within the lamp housing 11. Additional components may be present, but are not shown.
  • the volume of the interior of the lamp housing 11 with the end wall 13 taking into account the electrical components 14 and 15 is in any case significantly greater than 3000 cm3.
  • the electrical components 14 and 15 are held in a carrier part 16 in which holding recesses 17 and 18 adapted to the electrical components 14 and 15 are provided.
  • a carrier upper part 21 provided with further recesses 19 and 20 is placed and the unit formed thereby from the carrier lower part 16, carrier upper part 21 and the electrical components 14 and 15 embedded therein into the interior of the housing 11 used and then closed the lamp housing 11 by means of the cover wall 13.
  • the residual volume 22 formed in this way has a volume of less than 3000 cm 3 if the two carrier parts 16 and 22 are suitably dimensioned.
  • the two carrier parts 16 and 21 thus serve as filler parts and are formed here from a suitable, foamed plastic and fixed in the interior of the lamp housing in a manner not shown.
  • the cover part 12 is also encapsulated in a pressure-tight manner and has therein a wall 23 on which a base 24 is fastened for holding a lamp 25; the cover part 12 with the wall 23 is encapsulated in a pressure-resistant manner.
  • adapter parts for example in the form of a reflector 26 or 27 are designed to limit the transparent surface 28 to values smaller than 8000 cm2, as shown schematically in the drawing. This ensures that the cover 12 can no longer be made of glass, but also made of plastic.
  • the building elements can be attached to carriers. Then the rest of the room would have to be filled with filler parts.
  • these filler parts could be a liquid that easily dissipates the heat generated on the components to the outside.
