Description

Luminous panel for poster backlight of static signaling.

Scope and prior art

The present invention relates to a backlit light panel with a light source based on electro-light diodes that has application in all types of signage signs for informational and / or public purposes.
Citarians

Signal signs are currently known static essentially constituted in the form of a box in whose interior housed lighting means such as tubes fluorescents used to backlight information panels transparent or translucent in which the information is found to report mounted in the box. Devices of this type are described in documents ES 1041578 and ES 1041865 respectively  referred to a perfected luminaire and a milestone advertising

These devices present among others the following drawbacks: reduced and very concentrated lighting in the area of light sources producing dark areas in the furthest positions, resulting in a little lighting homogeneous; a relatively high electricity consumption; a time of  reduced life with consequently high maintenance cost and generation of hazardous waste such as pipes fluorescent lighting.

Object of the invention

Starting from the state of the art previously described the invention aims at the development of a luminous panel that serves to backlight a essentially adhered plate or sheet on the front face of said luminous panel that allows a powerful and uniform illumination is say without dark areas and also present an electric consumption  reduced, said luminous panel being easy to manufacture and reduced maintenance

This objective is achieved through the characteristics indicated in claim 1. Other features and advantages of the invention result from the characteristics indicated in the dependent claims.

According to the invention a panel is provided bright to backlight a static signage sign such as a poster in the form of a plate or transparent sheet or translucent engraving, characterized in said luminous panel (1) because understands:

- an acrylic-based panel iron optical quality with a front portion on which the sign to illuminate and a later portion that is mechanized with a plurality of essentially V-shaped grooves that are distributed according to a reticular pattern throughout said panel plate;

- diode-based lighting means electroluminosos that are housed in longitudinal recesses that extend close to the upper and lower edges of said posterior portion; Y

- a sheet of reflective paper adhered on  the back portion of the panel iron covering its slits and their longitudinal grooves.

According to an additional feature of the invention is an advantage when the conforming grid pattern to which the V-shaped slits are machined is a grid of equidistant lines that extend respectively parallel and perpendicular to the respective upper edges and bottom of the back portion of the panel plate.

According to another additional feature of the invention is an advantage when the reticular pattern according to which the V-shaped slits are machined is a dot matrix with rows and columns equidistant from each other that extend respectively parallel and perpendicular to the respective upper and lower edges of the rear portion of The panel iron.

According to another additional feature of the invention, it is advantageous when the V-shaped grooves are formed at an angle between approximately 30 and 150 degrees, with a depth between approximately 0.25 and 1 mm, and with a mutual separation between approximately between 1.5 and
10 mm

Still agree with another additional feature  of the invention is advantageous when the panel plate has a thickness between approximately 6 to 12 mm, and being panel width preferably between 50 and 1000 mm

Brief description of the drawings

Other features and advantages of the invention  will result more clearly from the description that follows with the help of the attached drawings, referring to an example of non-limiting execution and in which:

Figure 1 shows a perspective view of a scheme of principle of the luminous panel according to the invention.

Figures 2A and 2B show so respective schematic view in rear and side elevation of the panel according to figure 1 for the case of slits distributed in a grid of lines.

Figure 2C shows a detail of a section of the luminous panel through the I-I line of the figure 3A.

Figures 3A and 3B illustrate so respective schematic view in rear and side elevation of the panel according to figure 1 for the case of slits distributed in a matrix of points.

Figure 3C shows a detail of a section of the luminous panel through the I-I line of the figure 4A.

Detailed description of a preferred embodiment

As can be seen through the drawings the luminous panel according to the invention, designated in general with reference 1 it is planned to illuminate later a static signage sign such as a sign in form of transparent or translucent plate or sheet engraved C which it is mounted not represented on the front of the luminous panel

This luminous panel 1 consists of an iron panel 2, lighting means 4 constituted by a plurality of LED 3 mounted on the panel plate as it is will describe in detail later and a sheet of paper reflective 5 arranged on the panel plate to reflect the light radiation provided by the lighting means such as  It will also be described in detail later.

The panel plate 2 is made up of  optical quality acrylic, such as methacrylate with a thickness preferably between 6 and 12 mm. This panel iron it has a front portion 20 on which the poster C is coupled to illuminate and a rear portion 21 in which a plurality of essentially V-shaped slits 210 that are distributed according to a reticular pattern 3 along the width and said panel plate as will be described later.

It can be seen that the lighting means 4, the plurality of LEDs, arranged in longitudinal slots 211 practiced in the posterior portion 21 of the panel, extending close to the upper and lower edges of said portion later.

Additionally it can be seen that the sheet of reflective paper 5 is adhered on the back portion 21 of the panel iron covering its slits 210 and its recesses Longitudinal 211.

As can be seen in greater detail in Figures 3A and 3B the machined V-shaped slots 210 in the rear portion 20 of the panel plate 2 are distributed according to a lattice pattern 3 in the form of grid of equidistant lines that extend between them respectively parallel and perpendicular to their respective upper and lower edges. But according to the invention, said pattern 3, can also be provided as a dot matrix with rows and columns equidistant from each other that extend respectively parallel and perpendicular to the respective upper and lower edges of the panel plate 2.

It should also be mentioned that in a way Preferably, the V-shaped slits 210 are formed with a angle between approximately 30 and 150 degrees, one depth between approximately 0.25 and 1 mm, and with a mutual separation between approximately 1 and 5 mm., it is also preferred that the panel plate 2 has a thickness between approximately 6 to 12 mm.

As mentioned above the poster to illuminate C is coupled to the front portion 20 of the iron panel, in the form deemed most appropriate by technicians in art and that this link is not described or represented in detail for not being part of the invention.

As will be easily understood by the people versed in art, the above described is merely illustrative of a preferred embodiment of the invention so that technical modifications of all are possible nature.

Enough that the object has been described of the invention, it only remains to point out that the embodiments derived from changes in shape, dimensions and the like, as well as those resulting from an application of the above disclosed, they should be considered included in its scope, so that the invention will only be limited by the scope of the following claims.
