  • Figure 8 shows a partially sectioned side view of the lamp according to Fig. 1 assembled with a detail of the sequential mounting of the reflector on the fixed plate.
  • a preferred embodiment of the lamp according to the invention comprises essentially:
  • the plate 1 10 has, integral therewith, an annular rack 1 10 fixed to the plate and in particular kept at a certain distance in the transverse direction Y-Y by means of spacers 1 1 1.
  • the plate may also have, fixed thereon, the electrical and/or electronic components of the lamp, for example comprising one or more of the following: a driver 120; an electronic control component 130 which manages a wireless connection, for example Bluetooth, and the lighting colours; a dimmer which manages the lighting intensity and emission of the lamp; a component 140 for supplying the voltage, for example 12V, to the control unit 130;
  • a reflector 220 in the example of embodiment of the lamp shown having a preferred substantially frustoconical, hollow, form with a side surface asymmetrically cut along a directrix so as to form a top surface 201 extending along a plane X-Z and an inclined side surface 202, the opposite edges 202a, 202b of which are respectively connected to the said surface 201 and to the outer edge of the plate 100;
  • the surface 201 is preferably made of a material suitable for causing at least a partial reflection of the light emitted by a light source and directed towards the said reflector;
  • the ring is integral with the reflector 200 to which it is connected, for example by means of screws and pins 221 with a female thread extending in the transverse direction.
  • the ring 300 and therefore the reflector 200 are axially fixed with respect to the plate 100 in the transverse direction Y-Y, but are able to rotate about an axis parallel to the transverse direction Y-Y, being moved by actuating means comprising a first motor 310, integral with the reflector 200, preferably mounted on the plate 301 of the ring 300.
  • the shaft of the first motor 310 is directed parallel to the transverse direction Y-Y and carries a pinion 31 1 for meshing with the teeth of the rack 1 10, so that rotational operation of the shaft causes rotation of the reflector 200 with respect to the plate 1 10.
  • the rotation of the reflector 200 is guided by guide rollers 320 which are designed to roll on the smooth inner annular surface of the racks so as to maintain the engagement and relative centring of the reflector with respect to the rack, during rotation of the reflector 200.
  • a system for reversible engagement of the reflector 200 and plate 100 is provided, said system in the preferred embodiment being in particular configured to allow the disengagement of the ring 300 from the rack 1 10.
  • the ring 300 has, integral therewith, a flange 330 substantially in the form of a "U", the arms 331 of which extending along the transverse direction Y-Y have corresponding holes 331 a for allowing engagement of a first end of a respective recall spring 315, the other end 321 of which is fixed to a slide 340 movable parallel to the plane X-Z of the plate 100 and the ring 300.
  • the slide 340 has, mounted thereon, an element for engaging together the reflector 200 and the plate 100, in particular the ring 300 and the plate 100, preferably consisting of a roller 320a which, when the lamp is assembled, is kept engaged against and-or below the inner annular surface of the rack 1 10, while allowing the relative rotation of the ring 300 and rack 1 10.
  • the roller 320a is movable together with the slide 340 against the recall action of the springs 315 so as to allow the disengagement of the ring 330 and therefore the reflector 200 from the plate 100.
  • the slide 340 may have for example an extension projecting in the transverse direction 341 for facilitating the displacement of the slide 340, for example by means of a simple pushing action using a tool such as a screwdriver (Fig. 8) inserted through a hole of the reflector 200, causing the slide 340 and therefore the roller 320a to be displaced towards the inside of the ring and causing disengagement of ring 300 and the rack 1 10, with introduction of a hinge pin connected to the reflector 200.
  • a tool such as a screwdriver (Fig. 8) inserted through a hole of the reflector 200
  • a flange 205 extending outwards and provided with a through-hole in a direction parallel to the plane X-Z of the plate 100, in particular in the longitudinal direction X-X, is connected to the side surface of the reflector 200.
  • a cover 400 is hinged together with the reflector 200, in particular by means of a gusset 405 extending inwards from an inner side surface of the cover 400 and a shaft 41 1 inserted into the hole of the flange 205, said shaft 41 1 extending in said direction parallel to the plane of the plate 100, in particular to the longitudinal direction X-X.
  • a motor 410 is arranged between the reflector 200 and the cover 400, in particular between the flange 205 and the gusset 405 where the reflector 200 are hinged, said motor 410 being able to cause the rotation of the cover 400 with respect to the reflector 200 about the hinge axis 41 1 , so as to obtain different opening/closing configurations of the lamp.
  • the motor 410 which is generally an electric motor, may in particular have a stator rotationally integral with the flange 205 and therefore the reflector 200, and a rotor rotationally integral with the gusset 405 and therefore with the cover 400.
  • the stator and rotor are preferably arranged coaxially around the axis 41 1 of the hinge for connecting together the reflector 200 and cover 400.
  • the cover 400 preferably reproduces the form of the reflector 200 with a surface 401 along the plane X-Z and side surface 402, so to engage on top of the reflector.
  • the cover has a light source which comprises for example: an LED 430, a support 440 for a LED, and an opaque diffuser 460 mounted on a support ring
  • said components may be for example coaxially assembled together inside the cover along its plane X-Z / surface 401.
  • All the active electronic components and components for controlling the various functions of the lamp may be operated and controlled remotely by means of a remote control device 500 available to the user.
  • the plate 100 is fixed to a wall/ceiling 1.
  • the reflector 200 (and therefore the cover hinged with it) are connected to the plate 100 (Fig. 8), for example by inserting the rollers 320 inside the rack 1 10, resting the ring 300 on the rack 1 10 itself and, by operating the slide 340, causing the engaging roller 320a to be displaced towards the inside of the ring so as to allow engagement between ring and rack, said engagement becoming stable upon release of the slide 340 which returns into the position recalled by the springs 315, drawing along with it the engaging roller 320a which is now stably engaged underneath the rack 1 10.
  • the source 430 with light emitting LED 430 may be switched on and the motor 41 1 operated so as to cause the relative rotation of the cover 400 with respect to the reflector 200 and the fixed plate 100;
  • the first motor 310 may be operated in either sense so as to cause rotation of the reflector 200 and the cover 400 with respect to the plate 100 and therefore the wall so as to produce a different angular orientation of the light beam emitted and reflected.
  • first motor 310 and second motor 410 for obtaining both an opening/closing movement of the cover 400 with respect to the reflector 200 and a rotation of the reflector and cover with respect to the plate 100
  • an embodiment of the lamp is also possible where only the second motor 410 is present in order to provide different opening and closing configurations of the lamp, which remains fixed in a single angular position which is pre-set at the time when it is mounted on the wall/ceiling.
  • opening/closing may be fixed or non-motorized, it being instead envisaged that the reflector and cover may be rotationally operated with respect to the plate 100.
  • the lamp according to the invention is functionally designed to allow variations in lighting due to the possibility of gradual opening/closing of the lamp cover and, if required, also rotation of the light beam about an axis perpendicular to the wall on which the lamp is mounted.
  • the assembly without visible components is moreover compact in terms of its structural design and may be easily assembled and also inspected in the case of malfunctions, owing to the possibility of rotating the reflector into an open or closed position with respect to the fixed plate which supports the electrical/electronic components.
