Definitions

  • the present invention relates to the field of lighting devices.
  • the object of the present invention relates more particularly to a lighting device with a decorative effect which is easily customizable and interchangeable.
  • the present invention will find many advantageous applications in the field of interior decoration of buildings receiving the public, customers or staff such as, for example, offices, waiting rooms, shops, schools, hospitals, hotels, restaurants, reception venues, museums, exhibition halls, administrations, etc.
  • the Applicant observes that there are already luminous tiles which include an element with a decorative effect.
  • the light tiles which have such an element with a decorative effect are not customizable or interchangeable since the element with a decorative effect is integrated directly into the tile. It is therefore integral with the slab.
  • the ready-to-wear retailer will not change all the lights in his shop for each change of display window, season or clothing collection.
  • the Applicant submits that the lighting devices known hitherto and comprising a light panel with a decorative effect are not satisfactory and do not allow them to be easily personalized and interchangeable.
  • the present invention aims to improve the situation described above.
  • An object of the present invention is to solve at least one of the problems of the technological background described above.
  • One of the objectives of the present invention is in particular to remedy the various drawbacks mentioned above by proposing a lighting device with a decorative effect which is simple and easy to install and whose decorative element is easily customizable and interchangeable.
  • the object of the present invention relates, according to a first aspect, to a lighting device with a decorative effect which is intended to be recessed into a false ceiling.
  • the lighting device comprises a frame, preferably of square or rectangular shape, integrating a luminous panel defining a lighting surface.
  • the removability of the plate is characteristic of the present invention.
  • the plate comprises a useful surface covering (at least partially) the lighting surface and a pair of mutually opposite edges comprising flaps forming an angle, called flap angle, less than 89° with respect to to the useful surface so that the flaps rest on the frame to hold the useful surface of the plate in position by clamping against the lighting surface of the slab.
  • flap angle is between 65° and 85°.
  • the flap angle is between 70° and 80°.
  • the plate comprises two predefined fold lines favoring the folding of said plate to form the flaps.
  • the plate is in the form of a square with a side substantially equal to 624 millimeters ( ⁇ 2 millimeters), each flap having a width substantially equal to 14 millimeters ( ⁇ 2 millimeters).
  • the plate is made of a translucent or transparent material.
  • the plate is made at least partially of thermoplastic polyester.
  • the plate is made of extruded thermoplastic polyester of the amorphous polyethylene terephthalate A-PET type.
  • the useful surface of the plate comprises a printing layer with a decorative effect using inks resistant to ultraviolet rays.
  • the light tile is an LED tile.
  • the object of the present invention relates, according to a second aspect, to an installation comprising a false ceiling in which is embedded a set of lighting devices as described above, which are arranged between them so that the plates are juxtaposed next to each other to form a luminous decoration on the ceiling.
  • the object of the present invention makes it possible to provide a lighting device with a decorative effect, now attractive, which offers ease of customization and interchangeability which opens the possibility of adapting the decor of a place by avoiding the need for an electrician to replace the complete luminous slab.
  • a lighting device according to an exemplary embodiment of the present invention will now be described in the following with reference together with the figures 1 and 2 .
  • the same elements are identified with the same reference signs throughout the description which will follow.
  • current light panels generally emit neutral light.
  • decorative elements are incorporated directly into the lighting device to produce a decorative effect when light passes through the decorative element.
  • One of the objectives of the present invention is to provide a lighting device with an attractive decorative effect which is customizable and interchangeable with a minimum of operations without the intervention of an electrician and without replacing the light panel.
  • the lighting device 100 proposed here within the framework of the present invention achieves this objective.
  • a lighting device 100 which has a decorative effect and which is intended to be embedded in a false ceiling 200.
  • the lighting device 100 conventionally comprises a frame 10 of square (or possibly rectangular) shape which incorporates a light panel 20.
  • the frame 10 of the device 10 therefore comes to rest on the metal reinforcement 210 of the false ceiling 200 which is formed by hangers and rails fixed directly to the ceiling.
  • Such an LED or OLED panel is particularly appreciated for its energy performance.
  • the concept underlying the present invention is to provide a decorative element 30 which is removable.
  • the removable decorative element 30 consists of a plate 31 structurally independent of the light panel 20 and of the frame 10.
  • Such a plate 31 is characteristic of the present invention.
  • the material selected at the end of the various tests carried out by the applicant offers complete satisfaction and makes it possible to meet the various economic, security, optical and mechanical constraints imposed by the field of lighting and buildings receiving the public, customers or Staff.
  • the Applicant has selected a plate 31 in a material belonging to the family of extruded thermoplastic polyesters and more particularly amorphous polyethylene terephthalate (or A-PET).
  • the plates 31 have a square shape with sides having a length of 624 millimeters.
  • a useful surface 31a is defined for this plate 31 which will come to cover the lighting surface 20a defined by the luminous panel 20 so as to produce a decorative effect when the light from the luminous panel 20 passes through the plate. 31.
  • the useful surface 31a of the plate 31 comprises a printing layer with a decorative effect using inks resistant to ultraviolet rays.
  • This plate 31 after printing, is then machined so as to undergo folding at the level of the folding lines 34.
  • the presence of these folding lines 34 favors the folding of said plate 31 to form flaps 32a, 33a which will be used to hold plate 31 against slab 20.
  • Such an angle a allows good gripping of the useful surface 31a of the plate 31 against the lighting surface 20a of the light panel 20.
  • All the patient or accompanying family has to do is send a photograph to the printer. After printing and machining, the hospital staff (or the dedicated subcontracted service) receives the printed and machined plate 31 and replaces the old plate in position with the new plate 31, without touching the electrical installation. and without risk of electrocution.
  • the new plate 31 is easily positioned against the luminous panel 20 in place thanks to the pinching exerted by the flaps 32a, 33a against the frame 10 of the panel 20.
  • machining of the plate 31 to form the flaps can be done by the end user, thanks to the presence of the fold lines 34 mentioned above. This facilitates the transport of the printed plate 31.
