Definitions

  • the present invention relates to a flush lighting apparatus for false ceilings.
  • flush lighting apparatuses consisting of a main cylindrical diffuser body which supports a separate transparent lens and a LED-holder circuit board with power wiring and possible heat dissipator.
  • Said main body comprises fastening means for connecting the lighting apparatus to the false ceiling.
  • connection elements screws, nuts and the like
  • the assembly of the lens in the diffuser is a particularly critical moment given the importance of the lens in ensuring quality of the projected light. Incorrect positioning may cause dazzling of the user underneath the apparatus.
  • the lens may accidentally fall, causing considerable monetary damage.
  • the lens is often the most costly component of a lighting apparatus.
  • the assembler must therefore pay the utmost attention and this causes a considerably waste of time.
  • a flush lighting apparatus for false ceilings characterised in that it comprises a lens including single block cylindrical diffuser snappingly supported by an intermediate body in which there is accommodated a LED-holder circuit board locked in working position by an overhanging dissipator also snappingly mounted onto the intermediate body.
  • the lens is integral with the diffuser eliminates the problem of assembly. Furthermore, with the lens being within the diffuser, the lens is certainly protected from accidental shocks during the step of assembly of the apparatus and/or fastening to the false ceiling.
  • a lighting apparatus comprises a single block cylindrical diffuser 1 comprising a transparent polycarbonate lens 2 supported by an intermediate hollow cylindrical body 3 by means of lateral protrusions 4 which engage side slots 5 of the diffuser 1.
  • Said lens 2 is obtained by integral moulding with the diffuser 1 shaped to also have an edge 20 on its lower side for coupling with the false ceiling and two cavities 21 separate from the lens 2.
  • the intermediate body 3 comprises lateral arms 6 for fastening to the false ceiling and internal protrusions 7 on which a LED-holder circuit board 8 rests fastened in said position by a dissipator 9 locked by appropriately shaped folded upper ends 10 of upper arms 11 of the intermediate body 3.
  • Said folded ends 10 are "beak"-shaped with a lower surface abutting against the complementary upper surface of the dissipator 9.
  • Said dissipator 9 comprises cavities 12 within which electrical material (not shown) connected to the circuit board 8 via vertical channels 13 is accommodated.
  • the assembly of the device is very simple being based solely on snappingly mounted systems.
  • the diffuser 1 is coupled with the intermediate body 3 engaging the side protrusions 4 (slightly flexible) of the latter in the slots of the diffuser 1, then the circuit board 8 is rested on the internal protrusions 7 and locked in said position by placing the dissipator 9 over said board 8.
  • Upper arms 11 are used to fasten the dissipator 9 (and therefore the board 8), whose "beak"-shaped folded ends 10 touch the top of the dissipator 9. In order to secure the block, said arms 11 must be slightly flexible, therefore allowing to fit the dissipator 9 into the upper part of the intermediate body 3.
  • the electrical material is arranged in cavities 12 and appropriately connected to board 8 by means of channels 13.
  • the dissipator 9, in addition to locking the board 8, is used to dissipate the heat produced during use of the lighting apparatus.
  • the cavities 12, in addition to accommodating the wiring, allow to dissipate the heat better (by increasing the heat exchange surface).
  • the lighting device is ready to be fastened to the false ceiling by means of the side arms 6, also slightly flexible, and the edge 20.
  • the assembler does not need to use tools.
  • the lens 2 being integral with the diffuser 1 does not need to be handled by the assembler; furthermore, being inside the diffuser 1, it is protected by the latter in the event of accidental shocks.
