Definitions

  • the object of this invention is a flexible recessed system for diffused, indirect, asymmetrical and direct, homogeneous lighting.
  • the field of application of this invention is the range of the technique of flexible lighting systems, preferably with LED.
  • Recessed lighting systems that can be installed in false ceilings, walls and wall linings, also for creative light decorations.
  • the LED or diode which is well known in the electronic fixtures industry, currently has multiple applications also in the lighting sector.
  • the LED applied to the light is an innovative technology being developed to improve the light beam, efficiency and chromatic performance.
  • LED diffusion is mainly due to taking advantage of the principle of spontaneous emission of light (photons) of certain semi-conductors that avoid overheating materials such as metal and their alloys, which represents a pending problem in the field of application of the known technique of reference.
  • LEDs in the field of application of this innovation are in fact, many and the strip version in particular, which are light strips that integrate into the architecture, adapting to decorations of outdoor and indoor environments.
  • LED recessed bars are also well-known in the state-of-the-art of reference, which, having a minimum aluminium thickness can be installed and embedded in the thickness of plasterboard and/or false ceiling.
  • the LED strips differ from bars for the type of support, which is made of flexible plastic in order to make the strips round and adaptable to surfaces where bars cannot be installed.
  • LED strips have smaller sections, usually approximately 10 mm wide by maximum 3-4mm high, they are usually, and not limited to, applied in lighting coves, in indoor and outdoor decorations along the perimeter lines of steps and stairs.
  • LED lighting systems made up of strips is that the user is unable to place other different light sources along the same line as the LED strip or bar since the relative supports are not suitable to house them.
  • Another pending problem is the impossibility to thoroughly clean the LED strip and bar lighting system, which results in subsequent deposits of atmospheric dusts and agents, which, overheating and burning result in deterioration of lighting efficiency on the line and their components and/or diodes.
  • This invention consists of a flexible recessed system integrated into the architecture, with direct and indirect asymmetrical diffused homogeneous lighting, which is particularly suitable for, and not limited to, indoor environments, consisting of a double extruded silicone profile and a ro-extruded profile that houses a LED lighting strip.
  • the initial purpose of this invention was to provide a flexible system that could adapt and integrate into any architectural environment without any application limitations, in particular and not limited to a curved and round shape.
  • the purpose of this invention is to take advantage of the silicone's properties of being especially flexible, resistant to temperature and a perfect electrical isolator to prevent untimely faults and deterioration of the light beam of the LED strip.
  • An additional objective of this invention was to provide a particularly flexible LED lighting system that would, in addition to flexibility, offer indirect, asymmetrical diffused light that is not dotted like typical LED strips.
  • Another objective of this invention was to create a flexible LED lighting system that would enable additional direct light sources along the lighting line, even after installing the lighting system.
  • the objective of this invention is the position of the said direct light emitting projectors whose light intensity distribution enables most of the light beam to be directly on the interested area so that the lighting system has a higher coefficient of use, thus resulting in energy saving with no dispersion and meeting the user's needs.
  • an additional objective of this invention was to create a flexible lighting system that would enable use in especially humid environments with vapours and aromas.
  • An additional objective of this invention was to create a flexible recessed lighting system that would prevent untimely deterioration of the light beam as a result of deposits of atmospheric dust that would alter lighting performance caused by the said dust burning on the surfaces.
  • an objective of this invention was to facilitate integration of the lighting system into architectural shapes with quick coupling of brackets equipped with strip springs that host the extruded silicone component.
  • this patent concerns a flexible lighting system, preferably but not limited to, indoor environments with recessed application for quick coupling of bracket type installation equipped with a spring that is easily installed and removed by the user.
  • the invention has a double extruded silicone profile ( fig. 1 ) and a co-extruded profile ( fig. 2 ) where the LED lighting strip is housed ( fig. 3 ).
  • a first extruded silicone profile and/or silicone compound with high IP protection ( Fig. 1 ) with excellent resistance to high temperatures and humidity, preferably but not limited to, metallic grey suitable for housing a second opal silicone extruded profile as a result of the internal mould in its section ( Fig. 4 ) to house a transparent co-extruded silicone profile onto which the LED strip is installed ( Fig. 3 ) and is tilted by 30° to enable homogeneous, diffused lighting.
  • the lighting system of this invention enables indirect, diffused, homogeneous and asymmetrical lighting, which, with quick coupling of a recessed system ( fig. 5 ) with brackets ( fig. 6 ) equipped with strip springs ( fig. 7 ) encase and host the silicone profile ( fig. 8 ) by means of traction compression, thus locking it into the desired position and integrating with the architectural shape.
  • the flexible lighting system is equipped with brackets provided with strip springs ( fig. 7 ) that facilitate recessed assembly, thus enabling it to adapt to any architectural shape, even if irregular, curved radius or round.
  • Another design shape of the lighting system provides, in addition to the fastening brackets ( fig. 9, 10, 11 and 12 ), brackets for locking ( fig. 13, 14, 15 and 16 ) and/or fastening as well as positioning along the line of indirect asymmetrical diffused light of extruded silicone profiles of one or more projectors ( fig. 17, 18, 19 and 20 ) with direct light that is easily positioned and removed by the user by means of the said brackets ( fig. 13, 14, 15 and 16 ).
  • the lighting system of this invention enables positioning of projectors ( Fig. 20 ) with direct light emission by means of dedicated brackets ( Figures 13, 14, 15 and 16 ), which are easily positioned ( fig 19 ) by the user ( fig. 18 ), even after installing the lighting system in order to meet the environmental lighting requirements ( Fig. 17 ).
  • the flexible recessed lighting system of this patent can be considered as a decorative element since it can take on irregular and non shapes without architectural application limits, it can be installed on the walls to create original decorative lighting fixtures.
  • the lighting system of this patent can be of any shape, even linear, or L-shaped, it can have mobile sections of flexible silicone, which obviously integrate into a single, totally movable body in order to have a circular or square or rectangular or even irregular shape and include, or otherwise, various direct light projectors.
  • the patent lighting system is designed according to what is described in the declaration of responsibility from no. 1 to no. 9.
