Definitions

  • the present invention relates to a device said type of lighting recessed in a partition, and comprising a deflector associated with light generating means, such as a light bulb.
  • the bulb, the deflector and the means electric power supply of the bulb are arranged inside a housing or recess provided in partition.
  • deflector lighting devices made of a metallic material, such as for example aluminum or stainless steel or any other suitable metal.
  • the metal being a good conductor of sounds, as a result such deflectors propagate and transmit sounds, which goes against efforts generally made to allow sound insulation of partitions, in premises for residential use or use professional.
  • the known devices do not have, for the reasons stated above, good resistance to fire.
  • the known deflector devices recessed are relatively difficult to set up. In indeed they require extremely precise dimensions and an arrangement also very precise with respect to the recess or receiving housing provided in the partition. Now, the production of partitions and recesses in partitions, on the one hand, and the installation of lighting devices recessed, on the other hand, call for trades different whose coordination is not often easy to achieve. The difficulty is even greater when the when it comes to aesthetically joining the edges of the deflector and edges of the opening or receiver housing provided in the partition.
  • the known deflectors are difficult to clean, due to the risk of scratches appearing during cleaning or dusting operations. This results in premature aging of the deflectors which harms both their effectiveness and their aesthetics.
  • the invention proposes to remedy the disadvantages above, and provides a lighting device comprising a deflector capable of being embedded, which is easy to set up, and has features sound, thermal, fire and electrical insulation excellent, and also easily serviceable and without degradation, while allowing an installation and a connection with the edges of the opening in the recess of aesthetically perfect.
  • the lighting device comprising a deflector capable of being embedded in a recess provided in a partition, the concavity of the deflector being facing the opening of said recess, the deflector being associated with at least one light generating means, capable of being arranged at one end of the deflector, is characterized in that that said deflector is made from material powder / hydrophilic powder, capable of solidifying once mixed with water including plaster.
  • the material is made of plaster and of water.
  • the deflector is extended on the side of the light generating means, by a bottom, itself extended by a substantially back wall parallel to the deflector, so as to define a cavity receiving said light generating means.
  • the part of the deflector adjoining the base is flat and parallel to the partition.
  • the return is arranged in the plane of the front face of said partition.
  • the periphery of the deflector is associated with leveling means ensuring the junction with the edge of the opening of the recess provided in the partition.
  • the invention is described below in the application to a hollow partition, but can be applied to partitions filled or solid walls.
  • the device lighting of the invention bearing the general reference 1, has a deflector 2 of general shape of half cap spherical, extended by a substantially vertical part 3 and flat, a substantially horizontal bottom 4 and a panel in return 5 of substantially vertical direction, and parallel to part 3.
  • the panel 5 is of slightly curved shape and defines with the bottom 4 and the part 3 a cavity 6 to inside which are likely to be arranged the lighting means 7 consisting of a socket 8, a bulb of the fluorescent type bearing the reference 9 and of means for connections 10 connected to a power supply source electric.
  • the lighting means 7 are known in themselves.
  • the lighting device of the invention is likely to be placed in a housing 11 provided for the interior of a double partition 12, 13, and more precisely a double partition consisting of a front panel 12 and a rear panel 13 separated by a space 14.
  • the panels 12 and 13 of the partition are for example plaster or any other similar material. They can also be made of wood or laminates.
  • Figure 2 shows a front view of the Figure 1.
  • the peripheral edge 15 of the device lighting 1 has a circular shape.
  • Deflector 2 thus presents a shape of a spherical cap truncated according to a diameter, the latter being symbolized by the axis 16.
  • the back wall bearing the reference 5 of the device lighting 1 is arranged in a height front position such that its horizontal upper edge 17 comes to level of the median axis 16.
  • a leveling joint 18, of general shape circular is provided between the peripheral edge 15 of the device 1, and the edge 19 of the opening provided in the front partition 12.
  • the diameter of the opening provided in the partition is slightly greater than the diameter of the device of the invention.
  • the patching material can be made of plaster or any other material compatible with the material constituting the lighting device and the material constituting the partition.
  • the lighting device can be easily made by molding or any other technique known, economically and in large series. The material employee allows a wide variety of shapes, sizes and aesthetic aspects.
  • the front panel 5 of the lighting device 1 slightly protrusion from the plane defined by the circular edge device device 1.
  • Figures 3 and 4 show a variant of embodiment in which the lighting device comprises a single deflector with a substantially cap shape spherical, slightly flattened at the top.
  • the deflector thus comprises, seen in section, a part 2A rounded, a substantially flat rear portion 2B and vertical and a rounded part 2C.
  • the edge peripheral 15 circular deflector defines a plane arranged substantially at the front face 12A of the partition 12 in which the device is embedded lighting 1.
  • the latter has a strip, preferably metallic and bearing the reference 20, arranged in a diameter 21 of the deflector.
  • Band 20 is substantially horizontal and of a height such that it can shelter the lighting means 7 and more precisely so as to hide from the view, in front view, these.
  • Figure 4 shows a front view of the device of FIG. 3 where the means lighting, known in themselves, are shown in dotted since arranged behind the front strip 20.
  • Figures 5 and 6 show a third form of embodiment of the invention in which the front wall 5 is plane, vertical and arranged substantially in the plane of the front face of the partition 12.
  • the peripheral edge of the opening 22 of the lighting device has a first part 15A of semi-circular shape and a second part 15B linear and arranged substantially horizontally.
  • the axis 23 is an axis substantially vertical.
  • the shapes of the deflector are not limited to those described and represented, and may include, in variant, square, rectangular section shapes, trapezoidal or polygonal, as shown in the figures 7 and 8.
