Definitions

  • the present invention relates to a lighting device, in particular capable of directing a light beam or cone in direction of an area or of an object to be illuminated, according to the preamble of claim 1.
  • the present description refers to a spotlight recessed in a suspended ceiling, without however losing generality.
  • Spotlights used for example in shop windows are known in the background art. All spotlights comprise a fixed frame, recessed in a suspended ceiling. A window is made in the frame.
  • a lighting body is connected to the frame and has a longitudinal extension axis.
  • the lighting body is movable with respect to the frame, at least along the longitudinal extension axis.
  • the adjustment of the position of the lighting body on the frame is carried out by means of connecting screws. This allows varying the width of the beam, which may be widened or closed on the area to be illuminated respectively by moving away or nearing the lighting body from/to the area to be illuminated. Once the adjustment is made, the lighting body is locked with respect to the frame, so as not to be able to move along the longitudinal axis.
  • US 3,700,885 discloses a lighting device according to the preamble of claim 1.
  • Documents DE 3447606 , US 4,232,361 , US 2012/0176799 and CN 104456329 are also considered prior art relevant to the invention.
  • the adjustment mechanism by means of screws is rather complex to use. Indeed, the user is to have a screwdriver to carry out an adjustment of the light beam and then is to act on each individual adjustment screw.
  • the whole adjustment mechanism is to be disassembled should there be a need to disassemble the lighting body, for example to replace the lighting body itself and/or the lightbulb or to perform any other type of maintenance.
  • the technical aim at the basis of the present invention is to propose a lighting device which overcomes the above-mentioned drawbacks of the known technique.
  • the present invention comprises a lighting device according to claim 1.
  • a lighting device comprises a frame that is configured to be mounted in a ceiling and/or in a suspended ceiling and/or in any type of vertical, horizontal or oblique support.
  • the device also comprises a lighting body having a longitudinal direction.
  • a lighting body having a longitudinal direction.
  • Such lighting body can be connected to the frame.
  • the lighting body is movable with respect to the frame, at least along the longitudinal direction.
  • the device further comprises a plurality of abutment members connected to the frame and defining a seat for receiving the lighting body.
  • the lighting body is insertable in the seat so as to be slidable with respect to the abutment members.
  • the lighting body has at least one abutment area, which is engageable by the abutment members so as to lock the lighting body inside the seat at least along the axial direction.
  • Such device resolves the technical problem because the mechanism for adjusting the position of the lighting body exclusively provides the engagement of the abutment members in one or more abutment areas. Indeed, the abutment members are capable of locking the lighting body in a predetermined position.
  • 1 indicates a lighting device according to the present invention.
  • the device 1 described preferably is of the type that can be oriented, that is to say it allows varying at least one angle of incidence of the light beam.
  • the device 1 is not limited to the orientation shown in Figure 1 because it may also be inserted in vertical and/or oblique walls and/or in floors. In this latter case, the lighting device 1 is overturned with respect to the orientation of Figures 1a and 1b .
  • the device 1 comprises a frame 2 that is configured to be mounted in a ceiling and/or in a suspended ceiling or in any type of vertical, horizontal or oblique support.
  • the frame 2 has substantially rectangular plan and is defined by four walls 3.
  • a frame 4 is placed at the base of the walls 3, while a bottom 5 is placed at the top of the walls 4.
  • the frame 2 is provided to be inserted in a seat (not illustrated) in which for the most part, hidden from view.
  • the walls 3 and the bottom 5 are hidden from view, while the frame 4 is facing the area to be illuminated and therefore is visible.
  • the frame 2 has a window 6, in particular made at the bottom 5.
  • window 6 preferably has a circular shape, but it may have any shape in alternative embodiments.
  • the device 1 comprises a lighting body 7 that can be connected to the frame 2 and at least partly inserted in the window 6.
  • Such lighting body 7 substantially has a prismatic shape.
  • the lighting body has the shape of a prism with a rectangular base, in particular a square base.
  • the lighting body 7 has a cylindrical shape.
  • the lighting body 7 has a first 7a and a second end 7b, which are opposite to each other.
  • the first end 7a is open and visible from the outside so that a light source 8 - for example a lightbulb - may project a light beam or cone outside the device 1.
  • the second end 7b is closed by a grid 9 and in use, is hidden from view. It is worth noting that the grid 9 is provided to allow the passage of the air so as to dissipate the heat generated inside the lighting body 7.
  • the lighting body 7 also has a longitudinal direction "B", shown for example in Figure 5 .
  • the lighting body 7 comprises a side surface 7c that substantially extends along the longitudinal direction "B".
  • the lighting body 7 can be oriented with respect to the frame 2.
  • the lighting body 7 may vary an angle of inclination and an azimuth angle with respect to the frame 2.
  • the lighting body 7 is movable with respect to the frame 2, along the longitudinal direction "B".
  • the device 1 comprises a plurality of abutment members 21.
  • abutment members 21 are connected to the frame 2 so as to define a seat 20 for receiving the lighting body 7.
  • Such lighting body 7 in particular is insertable in the seat 20 and may slide with respect to the abutment members 21.
  • the lighting body 7 has at least one abutment area 22, which may be engaged by the abutment members 21 so as to lock the lighting body 7 at least along the axial direction "B" inside the seat 20.
  • the lighting body 7 has a plurality of abutment areas 22 spaced apart along the longitudinal direction B.
  • Figure 7 shows a lighting body 7 having three abutment areas 22.
  • the abutment area 22 comprises a groove 27 made on the side surface 7c of the lighting body 7.
  • the groove 27 extends along a perimeter of the lighting body 7 and is arranged on a plane having section perpendicular to the longitudinal direction "B".
  • the lighting body 7 is switchable between a sliding configuration and a locking configuration.
  • the abutment members 21 are slidable on the lighting body 7 in the sliding configuration. Contrarily, the abutment members 21 are engaged in the abutment area 22 in the locking configuration. It is worth noting that if the lighting body has several abutment areas 22, each of them is associated with a respective locking configuration.
  • the lighting body 7 is configured to spontaneously pass from the sliding configuration to the locking configuration each time the abutment members 21 engage the abutment area 22.
  • the lighting body 7 does not spontaneously pass from the locking configuration to the sliding configuration.
  • the user applies a predetermined axial force on the lighting body 7.
  • the predetermined force required for such operation is greater than the weight of the lighting body 7 itself so that the lighting body 7 cannot pass into the sliding configuration only by gravity.
  • each abutment member 21 is transversely movable and in particular, perpendicularly movable, with respect to the longitudinal direction "B" of the lighting body 7.
  • each abutment member 21 may switch between a retracted position and an extended position. In the extended position, the lighting body 7 is in the locking configuration. Moreover, the abutment member 21 is extended towards the central axis of the lighting body 7. In the retracted position, the lighting body 7 is in the sliding configuration. Here, the abutment member 21 is further away from the axis of the lighting body 7.
  • the device 1 comprises elastic means 23 associated with the abutment member 21 to push it from the retracted position to the extended position.
  • elastic means 23 comprise a spring 24 associated with the abutment member 21.
  • the abutment member 21 is defined by a ball 25 connected to the frame 2. Such ball 25 is pushed by a respective spring 24 against the side surface 7c of the lighting body 7 when the lighting body 7 is inserted in the seat 20.
  • a ring 26, of smaller diameter than the ball 25 and integral with the frame 2 is placed between the ball 25 and the side surface 7c of the lighting body 7. Such ring 26 traps the ball 25, in particular acting as abutment for the ball 25 itself, which is pushed against it by the spring 26.
  • the ball 25 when the abutment member is in extended position, the ball 25 is abutting against the ring 26 and is inserted in one of the grooves 27 that define the respective abutment areas 22. Accordingly to push the ball 25 out of the groove 27, there is a need to exert a force in axial direction contrasting with the spring 24. Contrarily, the rotation of the lighting body 7 is not prevented because the ball 25 does not keep a rolling contact with the inside of the groove 27.
  • the device 1 comprises a support 28 for the lighting body 7.
  • Such support 28 has a ring portion 28a that, in use, surrounds the lighting body 7 and defines the seat 20.
  • the mentioned abutment members 21 are arranged on the ring portion 28a. It is worth noting that such ring portion 28a is countershaped with respect to the lighting body 7, that is to say it has a circular shape if the lighting body 7 is cylindrical (as in Figures 1a to 6 ), or a rectangular shape if the lighting body 7 has the prismatic shape of Figure 7 .
  • the device 1 also comprises a guide 29 connected to the frame 2, in particular fixed to the support 28.
  • a guide 29 is arranged parallel to the longitudinal direction "B" of the lighting body 7. Accordingly, the guide 29 substantially is perpendicular to the ring portion 28a of the support 28.
  • the lighting body 7 also comprises a slider 30 provided to be inserted in the guide 29 so as to slide inside the guide 29. It is worth noting that the guide 29 has a recess 29a that is countershaped to the slider 30 so as to prevent a rotation of the lighting body 7 about the longitudinal direction when the slider 30 is inserted in the guide 29.
  • the guide 29 has a pair of ends 29b, 29c.
  • a first end 29b is located in a distal position with respect to the frame 2, in particular with respect to the bottom 5.
  • a second end 29c is opposite to the first end 29b, and is located in proximal position to the bottom 5.
  • the recess 29a has a diverging portion 31.
  • Such diverging portion 31 is placed at the second end 29c of the guide 29 so as to facilitate the insertion of the slider 30 into the recess 29a when the lamp body 7 is inserted.
  • the device 1 comprises a tooth 33 inserted in the guide 29 to prevent the undesired release of the lamp body 7.
  • the tooth 33 in particular is placed close to the second end 29c of the guide 29.
  • the tooth 33 is switchable between an interfering configuration and an open configuration.
  • the tooth 33 is at least partly inserted in the recess 29a of the guide 29 in the interfering configuration so as to lock the extraction of the slider 30 from the guide 29.
  • the tooth 33 frees the passage for the slider 30 inside the recess 29a in the open configuration so as to allow the insertion and/or removal of the slider 30 into/from the guide 29.
  • the tooth 33 is elastically connected to the guide 29, it is capable of spontaneously passing from the open configuration to the interfering configuration. Vice versa, to pass from the interfering configuration to the open configuration, the tooth 33 is provided to be pushed by the mentioned slider 30.
  • the tooth 33 has an inclined surface 34 facing towards the second end 29c of the guide 29.
  • Such inclined surface is adapted to be pushed by the slider during the insertion of the lighting body 7 in such a manner as to cause the tooth 33 to rotate into the open configuration.
  • the tooth 33 spontaneously returns to the interfering configuration as described above.
  • the tooth 33 also has an abutment surface 35 facing towards the first end 29b of the guide 29 and in particular, opposite to the inclined surface 34.
  • the abutment surface is adapted to prevent the exit of the slider 30 from the guide under the action of the weight or of a slight force of traction.
  • the tooth 33 is configured to pass from the interfering configuration to the open configuration when the lighting body 7 is subjected to a predetermined axial force of traction equal to six times the weight of the lighting body 7 itself. Such force is in fact sufficient to move the tooth 33 also when the slider 30 is in contact with the mentioned abutment surface 35.
  • the guide 29 has a shorter length than the length of the lighting body 7. Both the first 29b and the second end 29c are open, that is to say they allow the slider 30 to enter and exit the recess 29a.
  • the guide 29 has a substantially similar length to the lighting body 7.
  • the first end 29b of the guide 29 here is closed by a cap 32.
  • the device 1 also comprises a pair of uprights 10.
  • Such uprights 10 extend along the orthogonal direction "A" away from the frame 2, and in particular from the bottom 5.
  • the uprights 10 are located behind the bottom 5, and therefore are hidden from view.
  • the lighting body 7 is arranged between the uprights 10 and is connected thereto so as to be able to vary its angle of inclination with respect to the orthogonal direction "A".
  • the longitudinal direction "B" of the lighting body 7 may be inclined with respect to the orthogonal direction "A”. It is worth noting that the lighting body 7 is connected to the uprights through the support 28 that defines the seat 20.
  • the uprights 10 are arranged at the window 6.
  • the uprights 10 are fixed to a base 17 inserted in the window 6.
  • Reinforcing ribs 19 connect each upright 10 to the base 17 so as to increase the structural rigidity.
  • the base 17 may rotate about the orthogonal direction "A" so as to modify the azimuth angle of the lighting body 7.
  • the device 1 also comprises a cover element 11 superimposed over the window 6.
  • the cover element 11 is arranged between the uprights 10.
  • Such cover element 11 has an opening 12 that is movable inside the window 6 so as to allow the orientation of the lighting body 7.
  • the cover element 11 is also inside the window 6 so as to vary the position and the shape of the opening 12. This in particular allows the opening 12 to follow the variation of inclination of the lighting body 7 with respect to the orthogonal direction "A".
  • the opening 12 is arranged between the uprights 10.
  • the opening 12 also has an edge 12a.
  • the edge 12a surrounds the lighting body 7 and preferably is placed in contact with the lighting body 7.
  • edge 12a is countershaped with respect to the lighting body 7.
  • the shape of the edge 12a is variable so as to remain in contact with the lighting body 7 at any inclination.
  • the cover element 11 comprises a pair of half-parts 13 connected to each other and movable away from/close to each other to vary the shape of the opening 12.
  • Each half-part 13 at least partly defines the mentioned edge 12a.
  • each half-part 13 has a semi-circular profile that partly defines the edge 12a of the opening 12.
  • the cover element 11 comprises a pair of coplanar flanges 14 juxtaposed to each other.
  • Each flange 14 defines a respective half-part 13.
  • the flanges 14 are connected to each other by at least one elastic element 15 so as to move away from/close to each other to adapt to the inclination of the lighting body 7.
  • the cover element 11 comprises a pair of elastic elements 15, each defined by a respective spring and connected to both the flanges 14.
  • the elastic elements 15 surround the opening 12 and accordingly, the lighting body 7.
  • the cover element 11 the result is that the lighting body 7 completely engages the window 6 so as to prevent the formation of an annular area that is free. Accordingly, a person located close to the lighting device 1 is not capable of observing the parts of the ceiling or of the suspended ceiling, given that the cover element 11, in particular the half-parts 13 thereof, always remain in contact with the lighting body 7 for any inclination the lighting body is caused to take on.
