Definitions

  • the invention relates to a lamp according to the preamble of claim 1.
  • Luminaires of the type mentioned at the outset which are to be used in rooms where there is a risk of explosion or firedamp, must meet the requirements of explosion or firedamp protection. Therefore, plastic luminaires, ie luminaires in which the luminaire housings are made of plastic, have been limited to 3000 cm3 volume in type of protection "d" (flameproof encapsulated).
  • the transparent lamp housing is usually made of glass; if plastic is used, the area that allows the light to pass through must be limited to 8000cm2 housing area.
  • the object of the invention is to provide a lamp of the type mentioned, in which the lamp housing and the cover trough is made of plastic.
  • a prerequisite for the design of the lamp according to the invention is, of course, that the lamp housing has an outer surface that is not larger than 8000 cm2.
  • the lamp housing is thus encapsulated separately in a pressure-resistant manner.
  • the luminaire housing which houses the components for supplying the lamp, is also encapsulated separately in a pressure-resistant manner, the free volume here also not exceeding 3000 cm3 in accordance with the regulations. So that there is no multi-chamber system of flameproof encapsulated spaces, a space is provided between the luminaire housing and the lamp housing, which is designed in the "increased safety" type of protection. In a preferred embodiment, the "increased safety" space is then encompassed or formed by a housing section which is integrally formed on the lamp housing.
  • the lamp 10 consists of a lamp housing 11 and a lamp housing 12 attached thereto, also called a cover trough 12.
  • the lamp housing 11 is closed by means of an end wall 13, so that the housing 11 together with the end wall 13 corresponds to the requirements of "pressure-resistant encapsulation".
  • Electrical components 14 and 15 are located within the lamp housing 11. Further components are not shown.
  • the volume of the interior of the lamp housing 11 with the cover 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 support upper part 21 provided with further recesses 19 and 20 is placed in the holding recesses 17 and 18 and the unit formed thereby from the lower support part 16, the upper support part 21 and the electrical components 14 and 15 embedded therein is inserted into the interior of the housing 11 and then by means of the cover wall 13 the lamp housing 11 closed.
  • 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 are formed here from suitable, foamed plastic.
  • the cover trough 12 has therein a wall 23, on which a base 24 is fastened for holding a lamp 25; the cover trough 12 is thus encapsulated with the wall 23 in a pressure-tight manner.
  • the free transparent surface 28 it is possible to limit the free transparent surface 28 to values below 8000 cm2 by installing adapter or filler parts, which are designed, for example, in the form of a reflector 26 or 27, as shown schematically in the drawing, although the total area of the covering trough is significantly higher. This ensures that the cover trough 12 can no longer be made of glass, but of plastic.
  • the two pressure-proof spaces in the luminaire housing 11 or in the lamp housing 12 are thus separated from one another with increased security by the space 33 and a multiple system is thereby avoided.
