Definitions

  • the present invention relates to an improved section bar for furniture, furnishing complements or the like, for roofing installations, such as pergolas or curtains, and in general for all structures or installations in which lighting is provided and/or required.
  • strips of lights preferably strips of LED lights (also known as “led strips")
  • strips of lights preferably strips of LED lights (also known as “led strips")
  • extruded section bars of polymeric material for example, silicone
  • the LED strip is not removable and, therefore, a possible failure of the latter (for example when one or more LED diodes blast) requires the disposal of the section with the faulty LED strip, without any possibility of reuse.
  • the LED strip is removably inserted inside a closed longitudinal cavity which is defined inside the section bar.
  • a termination of the LED strip is inserted inside the section bar at the open end of the latter and is then made to slide along the longitudinal extension of the section bar itself.
  • the extruded sections are then hermetically closed at their ends open.
  • sections are used whose cross-sectional dimensions are appropriately oversized so as to be able to obtain inside it a cavity having dimensions with the cross-section considerably larger than those of the LED strip, and this in order to allow an easy longitudinal sliding of the latter into and along the aforementioned cavity.
  • this solution is not satisfactory since the transversely oversized profile, in addition to having a more important visual impact, is generally not suitable for being applied to furniture or furnishing accessories, in particular in order to define the finishes or seals at their edges.
  • US 2010/0061095 describes a device comprising a tubular plastic profile which is provided with an internal cavity for housing a flexible printed circuit comprising a plurality of LED diodes.
  • the printed circuit is inserted inside the section through a longitudinal opening which is subsequently closed thanks to a tongue-and-groove coupling defined by corresponding parts (i.e. a shaped appendix and a corresponding shaped recess), both obtained in the tubular section itself.
  • US 2014/0268736 describes an extruded profile made of polymeric material to contain an LED strip and thus create a lighting device.
  • the section defines an internal cavity configured to house the LED strip which is accessible through an opening which, under use conditions, is closed by folding an articulated portion of the section, which then interlocks with another wall of the section.
  • WO 2005/106320 presents an elongated and flexible lighting system which includes a section bar made of flexible material and an array of light sources mounted on a flexible printed circuit configured to be housed inside a longitudinal cavity provided in the profile itself.
  • the section includes a slit that connects the internal cavity with the outside and allows to insert the printed circuit board inside the cavity itself. In conditions of use, the slit is closed - and the cavity is therefore isolated from the outside - by means of clips, or directly by filling the cavity with a filler material.
  • this solution is not fully satisfactory as it requires additional external components (such as clips) or, by filling the cavity with material, in the event of a fault, it is no longer possible to remove the LED strip and it is therefore necessary to replace the whole device. In any case, by completely isolating the internal cavity from the outside and, in particular, since there is no adequate ventilation inside said cavity, there is the risk of having undesired overheating.
  • the object of the invention is to propose section bar which eliminates all the drawbacks of the known solutions.
  • Another object of the invention is to propose a section bar to protect a LED strip from the external environment.
  • Another object of the invention is to propose a section bar in which a LED strip can be inserted simply, easily and quickly.
  • Another object of the invention is to propose a section bar which allows to have a uniform light substantially along its entire length.
  • Another object of the invention is to propose a section bar whose length is easily customizable and adaptable, even when installed and at the moment of installation.
  • Another object of the invention is to propose a section bar which allows a suitable ventilation for the LED strip destined to be housed inside said section bar.
  • Another object of the invention is to propose a section bar that is both improved and/or alternative to the traditional ones.
  • Another object of the invention is to provide a section bar which has an alternative characterization, both constructive and functional terms, compared to the traditional ones.
  • Another object of the invention is to propose a section bar which can be obtained in a simple, rapid manner and with low costs.
  • Another object of the invention is to provide a section bar that can be produced in series, quickly and efficiently.
  • Another object of the invention is to provide a section bar that has high standards, both functional and constructive, and at the same time of an accessible cost, thus allowing the possibility of its widespread distribution.
  • Another object of the invention is to realize a section bar that can be used with standardized dimensions of LED strips and/or the type and dimensions commercially available.
  • Another object of the invention is to provide a section bar which can be used as a gasket and/or as a finishing profile and/or as a decoration.
  • Another object of the invention is to propose a lighting device which can be obtained and configured in a simple, rapid and low-cost way and which allows to obtain an illumination that is overall aesthetically pleasing and, thus providing the observer with the feeling of being in front of a high quality solution, both aesthetically and functionally.
