Definitions

  • the present invention is in the field of domestic lighting appliances and relates more particularly to a sealing equipment for a luminaire of the type of those intended to be mounted in a recess in a wall of a building such as not limited to a false ceiling, vertical partition wall and other.
  • a luminaire is known in the field of activity under the term spot.
  • Luminaires are known from the state of the art intended to be embedded in bores made in partition walls of a building such as a dwelling, a commercial space and the like. These walls may be of the type known under the trade name of "PLACOPATRE" and may constitute the false ceilings of the building.
  • these luminaires comprise a lighting lamp comprising a bulb, usually of frustoconical shape, extended rearwardly by a cylindrical shaped base adapted to be electrically connected to the electrical distribution network of the building.
  • This lamp is removably housed in a support formed of a fitting sleeve adapted to be engaged in the through-hole of the partition wall and a flange provided at one of the two ends of the sleeve.
  • This flange cleanliness is provided to bear against the apparent face of the partition or front face and mask the drilling in the latter.
  • One or more resilient rods integral with the sleeve and adapted to engage with a groove in the bulb at its large base, provide removable attachment of the bulb in the support and more specifically in the housing that determines said socket.
  • the bulb is engaged and fixed in the socket of the support and elastic hooks carried by the support sleeve, under the effect of their elasticity come to bear against the rear face of the partition wall at the periphery of the through bore formed in the latter.
  • the support is biased in the through bore and the collar of the sleeve bears against the apparent face of the partition wall.
  • the rear face of the partition wall is usually turned to a technical vacuum including welcoming the electrical distribution network of the building.
  • non-habitable or unusable volumes are constituted by the dead volumes of the house or by the technical voids, for example those located under the roof or those located between a main ceiling and a false ceiling and usually hosting the distribution networks electric and others.
  • the fixing brackets of the luminaire are likely to deteriorate the wall when it is plaster-type friable material.
  • the object of the present invention is to overcome the drawbacks previously mentioned by implementing a sealing equipment for a luminaire of the type previously described, this sealing equipment being able to ensure a tight separation between the non-habitable volume in which the luminaire penetrates. and the living space to be illuminated.
  • Another object of the present invention is sealing equipment that can be easily adaptable to already installed luminaires.
  • the sealing equipment according to the invention intended to equip a luminaire intended to be embedded in a through bore formed in a wall ensuring the separation between a habitable volume to be illuminated and a technical vacuum, is essentially characterized by it is formed of an envelope forming an airtight and water-equipped chamber equipped at the front of an opening for introducing the luminaire, said envelope being provided by its rear part to be engaged in the technical vacuum behind the partition wall, and said envelope having sealing means for sealing said wall and the periphery of the through orifice.
  • the living space is perfectly isolated from the technical volume and no passage of air is established between these two volumes.
  • the luminaire is physically isolated from the technical vacuum and is thus protected from dust and moisture as well as the depredation of rodents.
  • the sealed envelope is made of a material with a low coefficient of thermal conduction.
  • This envelope thus provides thermal insulation between the technical volume and the living space and also provides thermal insulation between the luminaire and the technical vacuum. Thermal bridges will be minimized.
  • the sealed envelope has a cylindrical sleeve shape by which it is intended to be engaged in the through bore formed in the partition wall, said sleeve shape being provided to accommodate the support of the lamp, this form of cylindrical sleeve being formed between a rear shoulder and a front flange in the form of a circular ring, said front flange and said rear shoulder being respectively provided to bear against the apparent face of said partition wall, or front face and against the opposite face of said wall or rear face and this at the periphery of the through bore, the inner face of the envelope of said rear shoulder being provided to receive in support of the fixing hooks of the luminaire support.
  • the luminaire will be thermally insulated from the partition wall that supports it, which greatly reduces the importance of the thermal bridges that can be created between these two elements.
  • the casing has a through bore passing through a cable for supplying electrical energy to the lighting lamp, said piercing being associated with a sealing membrane.
  • the envelope is made of a flexible material, elastically deformable. Such an arrangement, by deformation of the envelope, allows the establishment of the sleeve in the through hole of the wall.
  • the subject of the invention is also a luminaire of the aforementioned type essentially characterized in that it comprises an envelope according to the invention.
  • the luminaire is associated with a second collar of cleanliness disposed between the collar of the socket of the lamp support and the collar of the sealed envelope, said second collar comprising a housing provided for welcome the collar of the waterproof envelope.
  • the flange is intended to protect the visible face of the blackening wall formed for the prior arrangements, in particular by heating marks usually resulting from the heat generated by the bulb and transmitted by conduction, by direct contact, to the face. apparent from the wall, by the collar of the lamp holder.
  • the housing that includes this second flange clean, in particular allows to absorb the thickness of the collar of the envelope so that it can be applied against the apparent face of the wall.

  • This lamp support 20 is designed to removably receive a lighting lamp 21.
  • a lamp 21 comprises a bulb substantially of frustoconical shape, whose small base is extended towards the rear by a base.
  • the base is intended to be connected by an electric cable C to the electrical distribution network of the building.
  • the socket 201 of said support 20 has elastic rods 203 intended to be engaged in a groove made in the lamp envelope, at the level of the large base of said lamp .
  • the support 20, opposite the cleaning collar 202, is equipped with elastic hooks 204 fixing.
  • the sealing equipment 1 is formed of an envelope defining the internal chamber 15.
  • This chamber 15 is airtight and watertight.
  • This envelope 1 is equipped with a front part 13 provided with an opening 10 for introducing the luminaire 2 into the internal chamber 15, the opening 10 forming the front part of the internal chamber 15.
  • the front parts 13 of the 1 and the chamber 15 are those facing the living space 4.
  • the envelope 1 is provided with a rear portion 16, in the form of a dome for example, and a central portion 11 developing between the rear portion 16 and the front portion 13.
  • the chamber 15 is formed in the rear portion 16, in the central portion 11 and in the front portion 13.

  • These fixing means in addition to the immobilization of the casing in the through hole 30 provide a thermal seal between the technical vacuum 5 and the living volume.
  • these means greatly reduce heat transfer between these two volumes, they also provide a seal to air, water, and water vapor.
  • the fixing means of the sealed envelope 1 to the partition wall 3 are formed by the central portion 11 of the casing 1 and for this purpose, this central portion adopts a cylindrical sleeve shape.
  • These means are furthermore formed by a rear shoulder 12 of the casing, located between the sleeve 11 and the rear part 16 of the casing and by the front part 13 of said casing, said front part 13 forming an elastically deformable collar , in the form of a circular crown.
