  • the invention also relates to a false ceiling provided with such lamp, characterized in that it comprises modular panels and a frame of longitudinal members and cross-members, which acts as a supporting structure for said modular panels, wherein at least one of said cross- members is constituted by said lamp.
  • Figure 1 is a perspective view of the lamp according to the invention
  • Figure 2 is an exploded enlarged view of the lamp according to the invention
  • FIG. 3 is an enlarged detail of the lamp according to the invention.
  • Figure 4 shows a step of installing a lamp according to the invention

  • the lamp 10 is shown assembled and in the position for installation, while in the enlarged detail in Figure 2, at one end of the profile 11, its components are clearly visible.
  • the quick coupling means 13 comprise, at each end of the profile 11 , a tab 15 which protrudes from it and is adapted to be inserted into a slit 16 of the supporting structure 14, as can be seen in Figure 4.
  • Figure 3 note that the tab 15 is folded onto itself substantially in a V-shape, which is adapted to deform elastically upon its insertion into the slit 16.
  • Figure 4 shows a step of installing the lamp 10, during association with an element of the supporting structure 14.

  • the element of the supporting structure 14 with which the lamp 10 is associated is a longitudinal member 18 of a frame of a false ceiling 40 and the supporting structure 14 is the frame.
  • the profile 11 has the same width as the standard width of the cross- members of a frame for modular false ceilings.
  • the tabs 15 are conventional, already in use in the frames of false ceilings made with cross-members and longitudinal members, and they are provided by cutting and folding a plate-like metallic element.
  • the profile 11 has a cavity that accommodates at least partially the lighting means 12. These latter means comprise a series of LEDs 19 on circuits 20 which are conveniently mounted on a dissipating thermal ribbon 21.

  • the diffuser element 23 is constituted by a substantially plate-like and transparent or semitransparent solid body, which is juxtaposed edgeways with respect to the LEDs 19 and extends outward from the profile 11. It is preferably made of extruded PMMA (polymethylmethacrylate), worked by way of laser cutting and etching, for example to create parallel scoring on the outer surface of the face arranged opposite the face juxtaposed with the LEDs 19 and/or substantially circular etchings distributed on one or both of the faces of greater area, in the part protruding from the profile 11.
  • PMMA polymethylmethacrylate
  • the diffuser element 23 is positioned substantially edge-on, protruding outward of the supporting structure 14, in order to obtain a bi-symmetrical lighting, as shown in Figure 6.
  • the diffuser element 23 is conveniently provided with a recess, adapted to accommodate the portion of tab 15 inserted into the profile 11 and shaped substantially complementarily thereto, and it is fixed to the profile 11 by way of a third grub screw 28 that passes through both the diffuser element 23 and the two walls of the profile between which it is inserted, at special through holes, of which a third hole in the two layers of the profile 11 is designated with the reference numeral 29 and the hole on the diffuser element 23 with the reference numeral 30.
  • the diffuser element designated with 123
  • the diffuser element is constituted by a solid body that is substantially shaped like an upside-down T in cross-section and is transparent or semitransparent and is juxtaposed edgeways with its central portion 127, core of the cross- section, with respect to the LEDs 19 and extends outward from the profile 11. Its association with the profile 11 is similar to the version described previously and occurs by inserting and fixing its central portion 127 between the two walls of the profile 11.
  • the diffuser element 123 is also made of PMMA, in this case preferably in an opal finish that acts as a screen, and has the same width as the profile 11 , in order to obtain a diffuse lighting in the space.
  • the diffuser element 223 is associated with the profile like the previous diffuser element 123, by inserting and fixing its central portion 227 between the two walls of the profile.
