Definitions

  • the subject of the present invention is a flush-mounted lighting apparatus equipped with a plurality of light sources that can be oriented and manoeuvred from inside.
  • orientable flush-mounted lighting apparatuses consist of either a single light source or a number of light sources, which, in fact, constitute mutually independent illuminating bodies.
  • the light sources are directed, or positioned according to appropriate directions, exploiting mechanisms that are able to perform simultaneously or consecutively a rotation with respect to a vertical axis and a rotation with respect to a horizontal axis.
  • Rotation according to the horizontal axis may be achieved by hinging the support of the light source to the mobile ring in such a way that the axis of the hinge itself is at the same time perpendicular to and incident upon the vertical axis of rotation.
  • rotation about the horizontal axis is achieved by means of a hinge, the axis of rotation of which is tangential to the mobile ring and perpendicular to the vertical axis.
  • each light source has a mechanism of its own in order for it to be oriented, but above all has an opening of its own from which the flow of light is emitted.
  • flush-mounted element is equipped with a number of light sources
  • modular elements set alongside one another are used.
  • Document DE 38 30 076 describes a light fixture comprising a housing with bevelled side walls and an upper wall.
  • the light fixture disclosed in DE 38 30 076 is provided with a central light source for ambient light hanging from the housing upper wall down and a plurality of spot light sources seated in an own hole of the bevelled side walls of the housing.
  • Each spot light source comprises a bracket which enables a rotation about an axis substantially parallel to the side wall of the housing on which the light source is mounted.
  • a purpose of the present invention is therefore to provide a flush-mounted lighting apparatus, equipped with a number of light sources, which enables convergence, in a single hole, of a number of luminous fluxes in such a way as to provide a concentrated or point-like illumination.
  • a flush-mounted lighting apparatus equipped with a number of light sources, which enables convergence, in a single hole, of a number of luminous fluxes in such a way as to provide a concentrated or point-like illumination.
  • the flush-mounted lighting apparatus equipped with a number of light sources, according to one first embodiment of the present invention is designated as a whole by the reference number 30.
  • the lighting apparatus 30 consists of a cylindrical body 4, closed at the top end, which constitutes the load-bearing structure of the lighting apparatus 30.
  • the body 4 has a bottom reflecting element 1 provided with a mouth 47, from which the flow of light is emitted.
  • a light source 22 Inside the body 4 are housed, together with their corresponding systems of articulation, both a light source 22, in a practically central position, and two or more light sources in lateral positions, these latter light sources being designated by the reference numbers 20 and 21, as illustrated in Figures 1-3.
  • the articulation system is represented by two lateral metal brackets.
  • the first side bracket 2 is hinged to the body 4 by means of an appropriate system which enables rotation of the light source 20 about the vertical axis, this rotation being achieved by using a turned element 5 threaded on the outside at one of its ends, namely the one that comes out of the body 4.
  • the second side bracket 3 instead, enables rotation of the light source 20 associated to it about a horizontal axis.
  • the latter light source is constrained in such a way that it follows a trajectory according to the arc of a circle 24 obtained, by punching, on the first side bracket 2.
  • the light source 21 is supported by a first side bracket 23 and by a second side bracket 26, which are altogether similar to the brackets 2 and 3 described previously.
  • the circular trajectories of the light sources 20 and 21 are consequently obtained by means of respective grooves 24 and 25, each of which being made on the respective second side bracket 3 and 26.
  • the first side bracket 2 (and 23) and the second side bracket 3 (and 26) are coupled together by means of a system made up of a sliding pad 7 made of a thermoplastic material (suitable for the operating temperatures involved and with good properties of ease of slip), a teflon blank 8, which has a friction function, a Belleville spring washer 27, the purpose of which is to recover the play, and a knurled turned element 9, which has the purpose of clamping the second side bracket 26 on the first side bracket 23 without any need for the installer to use particular tools.
  • a sliding pad 7 made of a thermoplastic material (suitable for the operating temperatures involved and with good properties of ease of slip)
  • a teflon blank 8 which has a friction function
  • Belleville spring washer 27 the purpose of which is to recover the play
  • a knurled turned element 9 which has the purpose of clamping the second side bracket 26 on the first side bracket 23 without any need for the installer to use particular tools.
  • the articulation system of the central light source 22 is also made up of two metal brackets.
  • the first central bracket 10 is pivoted to the body 4 by means of the fulcrum 38, so enabling rotation about the vertical axis, whilst the second bracket 11 is pivoted on the first bracket 10, so enabling rotation about the horizontal axis.
  • the first side brackets 2 and 23, and the first central bracket 10 are pivoted on the body 4 using a turned element 5 having a hole and threaded on the outside of one of its ends, namely the end which comes out of the body 4.
  • the first side brackets 2 and 23, and the first central bracket 10 rotate about the vertical axis, identified by the axis of the turned element 5, in a way altogether independent from one another. This is possible since a teflon washer 12 is set between one bracket and the other, each one of the brackets being fixed to the turned element 5.
  • a Belleville spring washer 13 is used also in this case, the Belleville spring washer being placed between the outer surface of the body 4 and a nut 6.
  • brackets are moreover designed in such a way as to prevent the light sources from interfering with one another, whilst an absolute detent 14 is obtained by means of an appendage made out of a sheet metal disk 40, also this disk being hinged together with the turned element 5 and being fixed to the latter.
  • the same sheet-metal disk 40 moreover enables clamping of the side brackets 2 and 23 in a given position by means of the action of screws 15.
  • the dish 1 is inserted in the body 4, thanks to the presence of leaf springs 18, which, in addition to guaranteeing a good force of retention, enable the dish 1 to be easily released for removal.
  • a steel safety wire is also present, which keeps the dish anchored to the body in the case where the user fails to carry out installation of the product correctly.
  • the present articulation system enables the light sources 20, 21 and 22 to describe trajectories lying on a hemispherical surface, so that a point-like or concentrated illumination is achieved.
  • bracket 23 enables the light source 21 to move in the direction of the double-headed arrow H
  • bracket 2 enables the light source 20 to move in the direction of the double-headed arrow F.
  • the above movements may be combined with the movements allowed by the bracket 3 (or 26) along the arc-shaped groove 24 (or 25) which enables the light source 20 (or 21) to move in the direction of the double-headed arrow I.
  • the bracket 10 instead, enables the light source 22 to move in the direction of the double-headed arrow G.
  • This movement can be combined with the one allowed by the bracket 11, which, thanks to the pin 38, can move in the direction of the double-headed arrow L.
  • the lighting apparatus 130 is made up of a cylindrical body 104, closed at the top end, which constitutes the load-bearing structure of the lighting apparatus proper and which has a bottom reflecting element 101 provided with a mouth 147, from which the flow of light comes out.
  • three light sources 120, 121 and 122 are present, the articulation means of which consist, for each of the light sources 120, 121 and 122, of a first external bracket 102, 123, and 110, respectively, the said external bracket being hinged to the body 104 so as to enable rotation of the corresponding light source about a substantially vertical axis.
  • the external brackets 102, 123 and 110 are basically L-shaped, where the shorter arm of each of the external brackets 102, 123 and 110 is hinged to the body 104 by means of a coupling between a turned element 105 and a nut 106, which enables rotation of the corresponding light sources 120, 121, 122 about a substantially vertical axis in a way whereby they are altogether independent of one another.
  • a second, internal, bracket 103, 126 and 111 is provided, each of the said brackets being connected, by means of a respective fulcrum 140, 141, and 142 to the respective external bracket 102, 123 and 110.
  • the internal brackets 103, 126 and 111 have a shape made up of three portions set at angles to one another, where one of the portions is hinged to the respective fulcrum 140, 141 and 142, and another portion supports the respective light source 120, 121, 122.
  • Each of the external brackets enables rotation of the lighting apparatus 130 about the vertical axis.
  • fulcrums designated by 140, 141 and 142 present at the ends of the respective external and internal brackets enable rotation of the respective light sources about the horizontal axis incident upon the vertical axis.
  • an orientable flush-mounted lighting apparatus is provided, equipped with a number of light sources the luminous fluxes of which are emitted from the same opening.
