Definitions

  • the description relates to mounting devices for lighting sources.
  • One or more embodiments may be used for mounting electrically-powered light radiation sources (such as solid-state sources, e.g. LED sources) into mounting structures such as e.g. drywall ceilings.
  • electrically-powered light radiation sources such as solid-state sources, e.g. LED sources
  • mounting structures such as e.g. drywall ceilings.
  • a lighting source may be mounted into a support structure, such as e.g. a countertop (e.g. drywall) ceiling, so as to project light downwards ("down light").
  • a support structure such as e.g. a countertop (e.g. drywall) ceiling, so as to project light downwards ("down light").
  • These mounting arrangements may be used for lighting devices having different features, e.g. depending on the characteristics of the support structures.
  • these ceilings may have thicknesses varying in a rather wide range (e.g. from 1 mm to 40 mm).
  • the available space above the support structure e.g. the space between the drywall and the ceiling
  • a possible solution involves the use of annular (plastic or metal) structures, adapted to accommodate a lighting module therein and provided on the external side with lever and/or spring systems, enabling the fixation on a ceiling.
  • mounting rings (again of a plastic or metal material) adapted to accommodate the lighting source therein and provided on the outside with various possible fixing mechanisms. Beside exhibiting less user-friendly features, such solutions may require a specific shaping of the openings in the mounting surface.
  • the invention relates to a device according to the preamble of claim 1, which is known, e.g. from US 5 236 157 A .
  • EP 1 348 903 A1 , DE 196 29 901 A1 and US 8 465 182 B1 are of interest for the invention.
  • One or more embodiments aim at overcoming the previously outlined drawbacks.
  • said object may be achieved thanks to a mounting device for lighting sources having the features specifically set forth in claim 1 that follows.
  • One or more embodiments may also concern a corresponding method according to claim 9.
  • One or more embodiments comprise a kit adapted to be installed easily and conveniently in different mounting conditions, without the use of specific tools.
  • reference 10 denotes on the whole a device adapted to be used for mounting lighting sources into an opening O provided in a mounting surface (structure) S.
  • Said surface S may include, e.g., a countertop (e.g. drywall) ceiling.
  • one or more embodiments may find application e.g. in mounting lighting sources into support structures comprising e.g. walls, furniture, lighting device arrangements etc.
  • surface S is shown as a disk-shaped element; such an exemplary representation has the only purpose of highlighting the fact that one or more embodiments may be mounted onto surfaces S the thickness whereof may vary greatly; the surface S may either be very thin (see e.g. Figures 3 and 10 ) or rather thick (see e.g. Figures 4 and 13 ), in a wide range of possible thicknesses.
  • the mounting surfacerce S may have a thickness ranging between 1 mm and 40 mm.
  • surface S may generally have any extension and shape.
  • Figures 1 to 13 refer by way of example to openings O having a circular shape
  • the embodiments may apply to openings O having any shape: for example, Figure 14 shows one or more possible embodiments adapted to mount one or more lighting sources at an opening O having a rectangular shape.
  • one or more embodiments may refer to a mounting device for lighting sources which in itself does not include the lighting source; for instance, the latter may be mounted into device 10 only after device 10 has been applied at mounting opening O.
  • a lighting source L e.g. a spotlight
  • a housing R which may also act as a reflector
  • Lighting source L may be any electrically-powered light radiation source, such as a solid-state light radiation source, e.g. a LED source. Such lighting sources are widely known in the state of the art, which makes it unnecessary to provide a more detailed description herein.
  • the lighting source L may be adapted to be fitted into device 10 e.g. by screws, bayonet fitting, coupling of the power supply electrodes, hook via collar elements, etc.: the wide range of implementations is known in the art, which again makes it unnecessary to provide a more detailed description herein.
  • One or more embodiments may refer mainly to device 10 and the features thereof, without a specific and limiting reference to the use of a given kind of lighting source L and/or to a particular method for mounting source L into device 10.
  • device 10 may include an annular frame 12 adapted to accommodate and mount an electrically-powered lighting source L therein, e.g. a solid-state lighting source, such as a LED source, schematically shown in combination with a possible housing R only in Figures 10 to 13 .
  • an electrically-powered lighting source L e.g. a solid-state lighting source, such as a LED source, schematically shown in combination with a possible housing R only in Figures 10 to 13 .
  • frame 12 may have a tubular, e.g. cylindrical, shape around a main axis X12.
  • the annular shape may be open or closed.
  • frame 12 may have an annular shape other than circular, e.g. quadrilateral, such as the rectangular shape exemplified in Figure 14 .
  • frame 12 may have any shape which enables the insertion thereof into opening O.
  • Figures 1 to 13 refer to a circular opening O, but said opening may be implemented in a wide range of different shapes and geometries, e.g. a rectangular shape as exemplified in Figure 14 .
  • frame 12 may have, at one of its ends, a peripheral flange 120 which, when device 10 is inserted into opening O, may abut against the rim of opening O (see e.g. Figures 8 to 13 ).
  • one or more retain mechanisms 100 may be provided, which at least grossly resemble clamps and which cooperate with the flange formation 120, in order to clamp the rim of opening O therein.
  • Figures 1 to 4 and 6 to 13 refer, by way of example only, to the presence of two mechanisms 100, which are arranged at mutually opposed positions with respect to annular frame 12.
  • Figure 14 shows the possibility of employing a different number of mechanisms 100, e.g. six mechanisms 100 arranged three by three on the opposed sides (which are longer, in the example of Figure 14 ) of frame 12, or respectively arranged in three pairs, each pair including two retain mechanisms 100 arranged in diametrically opposed positions with respect to frame 12, each of the mechanisms 100 facing, in a position diametrically opposed across frame 12, another corresponding mechanism 100.
  • This diametrically opposed arrangement may ease the achievement of a symmetric and balanced mounting condition.
  • only one mechanism 100 may be provided, e.g. by envisaging, in a diametrically opposed position, a hook formation adapted to establish a coupling between the rim of frame 12, e.g. in the vicinity of flange 120, and the rim of opening O.
  • mechanism 100 may comprise an arm 102 mounted on annular frame 12 and being adapted to tilt between:
  • arm 102 is fork-shaped and includes two branches 1020 each of which is proximally coupled (hinged) (see reference 102b) to frame 12, while the distal ends of both branches 1020 are connected with each other, e.g. via a bar defining the distal end 102a of arm 102b, optionally with a further formation 102c (which will be detailed in the following) extending bridge-like between the central portions of both branches 1020.
  • Reference 104 denotes an actuator member which, in one or more embodiments, may comprise an L-shaped element which may be mounted on frame 12 and is adapted to perform (in addition to an optional tilting movement inwardly of frame 12, which will be better detailed in the following), a general translation movement, sliding axially with respect to frame 12 (e.g. in the direction of axis X12).
  • actuator member 104 may thus be adapted to slide with respect to frame 12 and to reach a position adjustable between:
  • frame 12 and actuator member 104 may have complementary sliding formations, such as e.g. channel-shaped formations 1040 located on opposed sides of actuator member 104 (such channel-shaped formations are more clearly visible and specifically shown in Figures 2 and 4 ) adapted to slidingly cooperate with axial ribs 1200 (the latter being more clearly visible and specifically shown in Figures 1 , 2 and 4 ) which extend axially with respect to frame 12, so as to allow actuator member 14 to perform said axial translation movement with respect to frame 12 in the direction of axis X12.
  • complementary sliding formations such as e.g. channel-shaped formations 1040 located on opposed sides of actuator member 104 (such channel-shaped formations are more clearly visible and specifically shown in Figures 2 and 4 ) adapted to slidingly cooperate with axial ribs 1200 (the latter being more clearly visible and specifically shown in Figures 1 , 2 and 4 ) which extend axially with respect to frame 12, so as to allow actuator member 14 to perform said axial translation movement with respect to frame 12 in the direction of axi
  • the position reached through said sliding movement may be made selectively adjustable by providing, for example at the face of ribs 1200 facing inwardly of frame 12, a toothed formation 1200a adapted to brake the sliding movement of actuator member 104 along guides 1200.
  • toothed formation 1200a may have an e.g. asymmetric sawtooth profile, which may exert a strong braking (almost blocking) action on the movement of actuator member 104 in the direction away from the end of frame 12 where flange 102 is located.
  • actuator member 104 may comprise, e.g. in a generally L-shaped configuration:
  • the axial mobility of actuator member 104 with respect to frame 12, with the possibility (e.g. due to the cooperation with toothed formations 1200a) to adjust the position reached through such axial movement enables to position actuator member 104 in an axial position which is selectively determined with respect to frame 12 and is therefore adjustable in such a way as to correspondingly adjust the retain condition of arm 102, i.e. the tilting condition of arm 102 with respect to frame 12.
  • a cooperating cam-like mechanism which may include e.g. the presence of a pin on arm 102 (which may include, in one or more embodiments as exemplified herein, a bar formation 102c extending bridge-like between both branches 1020 of arm 102, in a middle position with respect to branches 1020).
  • the pin/bar 102c supported by arm 102 may therefore operate as a cam-follower, e.g. slidingly, with respect to a sliding surface 104c of actuator member 104: for simplicity of illustration, surface 104c is denoted as such only in the cross-sectional view of Figure 5 .
  • distal portion 104b of actuator member 104 radially protruding outwardly of frame 12, is adapted to exert an urging action onto arm 102, which brings (and keeps) distal end 102a of arm 102 in abutment against the rim of opening O in mounting surface S.
  • arm 102 may therefore be configured so as to act as a lever, the fulcrum whereof is located at the proximal end 102b.
  • actuator member 104 is mounted on frame 12 with the possibility of tilting (e.g. at pins 104d: see e.g. Figure 5 ), so that it may be brought to a respective insertion condition (see e.g. Figure 1 and Figures 6 to 8 ), wherein actuator member 104 is tilted inwardly of frame 12, so as to facilitate the movement of insertion of device 10 into opening O.
  • pins 104d may be located near the ends of toothed formations 1200a more outwardly of frame 12, so that they enable the tilting movement of actuator member 104 when member 104 is nearly completely extracted from the coupling condition with frame 12 (with the ribs 1200 engaging the grooves 1040, with reference to the examples herein).
