Definitions

  • the present invention is comprised in the technical field of backlighting of products and images in commercial equipment and furniture, images on lighted sign boards, light boxes and backlighting in general. More specifically it relates to the field of illuminated sign boards which are illuminated on the edge with glowing parts, and it particularly relates to a display panel provided with illumination by means of LEDs, the parts of which are assembled exclusively by means of adhesive attachments, avoiding the use of mechanical attachments.
  • display panels provided with illumination means to highlight an image adhered thereto are widely known and used. Said panels can be displayed by themselves or they can be part of the furniture, either in commercial settings or outdoors, as part of outdoor advertising.
  • These panels usually comprise illumination elements which project a light beam onto the surface of the panel in which the image to be shown is arranged.
  • said illumination elements are LED strips due to the advantages they have in terms of power consumption, flexibility, versatility, ease of installation and low heat generated.
  • the most common heat sinks consist of metallic elements which transmit and release heat into the atmosphere, therefore the larger the surface area said sinks have, the more efficient they are.
  • the problem of said sinks is that they add extra weight to the panel, and they can negatively affect the final appearance.
  • the object of the invention consists of an illuminated display panel the elements of which are attached to one another only by means of adhesive attachments, avoiding the use of mechanical fastening elements such as screws or the like, to thus overcome the problems set forth above.
  • the panel is formed by a base plate made of methacrylate, preferably PMMA (polymethyl methacrylate), with a thickness comprised in the range between 4 and 10 millimeters.
  • This plate can incorporate a surface that is mechanically engraved, by means of a laser or screen printed.
  • the option of using PMMA base plates formed with microlenses or microparticles is also contemplated.
  • a sheet preferably made of aluminum, which partially covers a bottom face and a perimetral edge of the plate, is also attached to the methacrylate base plate in which the sign board or advertising element to be displayed is arranged.
  • said sheet has a front face intended to face the bottom face of the plate, a rear face intended to face the outside, and a perpendicular twice-bent segment starting at the top of one of the perimetral edges thereof.
  • an LED strip is arranged which emits a light beam towards the advertising element.
  • a cooling tape with two-sided adhesive and heat conduction capacity is preferably used to dissipate the heat generated by the LEDs by means of the transmission thereof to the sheet which, in turn, dissipates it by contact with the surrounding air.
  • the attachment between the methacrylate base plate and aluminum sheet is performed by means of an adhesive tape, which can be one-sided or two-sided.
  • adhesive tape which can be one-sided or two-sided.
  • adhesive reflective tape for reflecting and directing the light beams generated by the LEDs towards the area wherein the advertising element is arranged is also contemplated.
  • the panel thus described made of lightweight and cost-effective materials, enables the flickering that usually occurs due to the screws present in the profile where the LED strip is fixed to be eliminated. It also favors a considerable reduction in production time, improvement of the final visual appearance of the product, and considerably reduces the dimensions of the edge of the panel not being used as an advertising site.
  • the illuminated display panel being described and schematically shown in figure 1 , is formed first by a methacrylate plate (1) for supporting an advertising sign board, said plate (1) having a perimetral edge (2), a top face (3) through which the sign board is shown, and a bottom face (4) to which the sign board is attached. As illustrated in figure 4 , the plate (1) also has a stepped recess (5) located on the perimetral edge (2).
  • the plate (1) is made of PMMA (polymethyl methacrylate) and has a polygonal geometry.
  • An aluminum sheet (6) is attached to the plate (1), partially covering the bottom face (4) thereof and the perimetral edge (2). To that end, said sheet (6) has a front face (7) intended to face the bottom face (4) of the plate (1), a rear face (8) intended to face the outside, and a twice-bent segment (9) starting at the top from one of the perimetral edges thereof.
  • the twice-bent segment (9) in turn has a first sector (10) perpendicular to the sheet (6), and a second sector (11), starting perpendicularly from the first sector (10), parallel at the top to the front face (7) and intended to be fitted in the recess (5) of the plate (1).
  • LEDs (12), provided with the corresponding power supply connections, are integrally attached to the first sector (10) on the front face (7) thereof. Said attachment is performed by means of cooling tape (13), with two-sided adhesive and heat conduction capacity, for dissipating the heat generated by the LEDs (12) by means of transmitting it to the aluminum sheet (6).
  • adhesive tape (14) for fixation.
  • said adhesive tape (14) is one-sided, whereas in the alternative embodiment illustrated in figure 5 , the adhesive tape (14) is two-sided, so it is hidden from view.
  • the reflective tape (16) is located inside the housing (15), below the LEDs (12) and fastened to the front face (7) of sheet (6) near the first sector (10).
