Description

Dispositivo de iluminación para estructuras panelables luminosas.Lighting device for structures bright panels.

El presente modelo de utilidad se refiere a un nuevo dispositivo de iluminación, especialmente concebido para estructuras panelables, que soportan cualquier tipo de imagen y que cuentan con medios luminosos que potencian la visibilidad de dicha imagen.This utility model refers to a new lighting device, specially designed for panelable structures, which support any type of image and that they have luminous means that enhance the visibility of said image.

El objetivo del presente modelo de utilidad es conseguir minimizar el consumo de energía eléctrica, para alimentación de los focos luminosos, conjuntamente con una óptima difusión de la luz, cuya intensidad se hace uniforme en toda la superficie de la estructura, y con una perfecta planimetría.The objective of this utility model is to minimize the consumption of electrical energy, to feeding of the light bulbs, together with an optimal diffusion of light, whose intensity becomes uniform throughout the surface of the structure, and with a perfect planimetry.

La invención resulta aplicable a estructuras panelables tales como carteles informativos o publicitarios, frentes de armarios, mostradores, cuadros luminosos, puertas batientes o correderas, etc.The invention is applicable to structures Panels such as informational or advertising posters, fronts of cabinets, counters, light boxes, swing doors or sliding, etc.

Background of the invention

En el ámbito de aplicación práctica de la invención se utilizan estructuras paneladas, en las que participa una placa de metacrilato, revestida por una cara con una lámina portadora de cualquier imagen decorativa, informativa, publicitaria, etc., generalmente materializada en una lámina físicamente independiente de dicha placa de metacrilato, aplicándose la fuente luminosa a uno o más de los bordes de la repetidamente citada placa de metacrilato, que normalmente se oculta en el seno de perfiles que constituyen un marco para tal placa, y habitualmente para una lámina o placa de revestimiento y protección posterior.In the practical scope of the invention paneled structures are used, in which it participates a methacrylate plate, coated on one side with a sheet bearer of any decorative, informative, advertising image, etc., generally materialized in a sheet physically independent of said methacrylate plate, the source being applied luminous to one or more of the edges of the repeatedly cited plate methacrylate, which is normally hidden within profiles that they constitute a frame for such a plate, and usually for a sheet or cover plate and back protection.

Es también conocido, por ejemplo a través del Modelo de Utilidad U 200900134, el utilizar como fuente luminosa diodos LEDs que, convenientemente distribuidos, se sitúan en correspondencia con uno o más de los bordes de la placa de metacrilato.It is also known, for example through Utility Model U 200900134, using as a light source LED diodes that, conveniently distributed, are located in correspondence with one or more of the edges of the plate methacrylate

Evidentemente si los LEDs se sitúan distribuidos sobre uno de los bordes de la placa de metacrilato, por ejemplo sobre su borde superior, la mayor intensidad de luz se situará en la zona también superior de la estructura, y su intensidad irá disminuyendo progresivamente hacia el borde más alejado.Obviously if the LEDs are distributed on one of the edges of the methacrylate plate, for example on its upper edge, the greatest intensity of light will be located in the also higher area of the structure, and its intensity will go decreasing progressively towards the furthest edge.

Tratando de obviar este problema es conocido repartir los LEDs por toda la periferia de la estructura, de manera que se consigue mejorar la homogeneidad lumínica, pero en el centro de la placa de metacrilato la intensidad lumínica es sensiblemente menor que en su periferia, de manera que la homogeneidad perfecta, que sería deseable, no se consigue con esta solución.Trying to ignore this problem is known distribute the LEDs throughout the periphery of the structure, so that is achieved improve the homogeneity of light, but in the center of the methacrylate plate the light intensity is substantially less than on its periphery, so that perfect homogeneity, which would be desirable, is not achieved with this solution.

En la Patente de Invención con número de publicación ES 2.291.604 se describe un dispositivo de iluminación y decoración, con el que se consigue una mejor difusión de la luz, es decir una mayor homogeneidad en la iluminación, y para ello dicho dispositivo consta de un marco en cuyo seno se establece una placa luminosa, por ejemplo a base de una pluralidad de tubos fluorescentes dispuestos en paralelo, que emite luz frontalmente haciéndola pasar a través de un elemento de decoración, transparente o traslúcido, con cualquier tipo de imagen impresa, complementándose este conjunto con un filtro que cierra frontalmente el marco citado.In the Invention Patent with number of Publication ES 2,291,604 describes a lighting device and decoration, with which a better diffusion of light is achieved, is say greater homogeneity in lighting, and for that said device consists of a frame in which a plate is established luminous, for example based on a plurality of tubes fluorescents arranged in parallel, which emits light frontally making it pass through a decorative element, transparent or translucent, with any type of printed image, complementing each other this set with a filter that closes the frame frontally aforementioned.

Esta solución presenta una problemática amplia y variada, que se centra fundamentalmente en los siguientes aspectos:This solution presents a broad problem and varied, which focuses primarily on the following aspects:

- El consumo de energía, es decir el consumo eléctrico para alimentar la placa luminosa es muy alto.- Energy consumption, ie consumption Electric to power the luminous plate is very high.

- Su estructura resulta muy voluminosa, lo que limita de forma muy considerable las posibilidades de aplicación práctica, de manera que resulta adecuado, por ejemplo, y tal como se especifica en su 4ª reivindicación independiente, para simular ventanas en paredes de locales que no disponen de tales ventanas, pero sin embargo resulta inaplicable a frentes para armarios o cualquier tipo de estructura donde se requiera de un espesor reducido.- Its structure is very bulky, which greatly limits the application possibilities practice, so that it is appropriate, for example, and as specifies in its 4th independent claim, to simulate windows in walls of premises that do not have such windows, but nevertheless it is inapplicable to fronts for cupboards or any type of structure where a thickness is required reduced.

Description of the invention

El dispositivo de iluminación que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, consiguiéndose con el mismo una difusión lumínica perfectamente uniforme, con un grosor reducido para la estructura y con un consumo energético mínimo.The lighting device that the invention proposes to solve the problem fully satisfactorily previously exposed, achieving with it a diffusion perfectly uniform light, with a reduced thickness for the structure and with minimal energy consumption.

Para ello el dispositivo de iluminación que la invención propone se basa en la utilización de una placa de metacrilato que recibe la luz a través de al menos uno de sus bordes, preferentemente a través de los cuatro, mediante sendas regletas porta- LEDs, que se complementa con una lámina portadora de la imagen de que se trate en cada caso, pero con la especial particularidad de que placa de metacrilato y lámina portadora de la imagen están sustancialmente distanciadas entre sí, manteniendo una situación de paralelismo, configuran y cámara aplanada a la que quedan enfrentados los LEDs, es decir que dichos diodos no iluminan el seno de la placa de metacrilato, por enfrentamiento al plano medio de ésta última, sino que iluminan dicha cámara reflejándose sobre la superficie interna de la placa de metacrilato para finalmente atravesar la lámina portadora de la imagen.For this the lighting device that the proposed invention is based on the use of a plate methacrylate that receives light through at least one of its edges, preferably across all four, by paths LED strips, which is complemented by a carrier sheet of the image in question in each case, but with the special particularity of which methacrylate plate and carrier sheet of the image are substantially distanced from each other, maintaining a parallel situation, set up and flattened camera to which LEDs are confronted, that is to say that these diodes do not illuminate the sine of the methacrylate plate, due to confrontation with the plane middle of the latter, but illuminate the camera reflecting on the inner surface of the methacrylate plate to finally cross the image carrier sheet.

Complementariamente y para conseguir la pretendida homogeneidad lumínica, la repetidamente citada placa de metacrilato incorpora en su cara interna una pluralidad de pequeñas protuberancias distribuidas al tresbolillo y considerablemente próximas entre sí, preferentemente de configuración sensiblemente cuadrangular, aunque tal configuración no es limitativa, con la particularidad además de que dichas pequeñas protuberancias son de dimensiones progresivamente crecientes a medida que se distancian del borde de la estructura en el que se sitúan los medios de iluminación.Complementarily and to get the purported light homogeneity, the repeatedly cited plate of methacrylate incorporates in its internal face a plurality of small bumps distributed to the tresbolillo and considerably close to each other, preferably of sensitive configuration quadrangular, although such configuration is not limiting, with the particularity besides that said small bumps are of progressively increasing dimensions as they distance of the edge of the structure in which the means of illumination.

Se produce de esta manera una compensación entre la merma de luminosidad determinada por el incremento de la distancia, y el tamaño de las protuberancias actuantes como elementos reflectantes, con lo que a la postre se consigue la homogeneidad lumínica perseguida, con la utilización de LEDs cuyo consumo es mínimo.There is a compensation between the decrease in brightness determined by the increase in distance, and the size of the protuberances acting as reflective elements, which in the end you get the pursued light homogeneity, with the use of LEDs whose Consumption is minimal.

Lógicamente la estructura así constituida se complementa con un marco que permite la fijación tanto de los LEDs como de la placa de metacrilato de la lámina portadora de la imagen, así como el correcto posicionamiento relativo entre estos elementos.Logically the structure thus constituted is complements with a frame that allows fixing both LEDs as of the methacrylate plate of the image carrier sheet, as well as the correct relative positioning between these elements.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como la estructura panelable se materializa en una placa transparente (1), preferentemente de metacrilato, que se monta sobre un marco soporte (2), provisto de una acanaladura (3) acusadamente sobredimensionada con respecto al espesor de la placa (1), de manera que en el fondo de dicha acanaladura (3) se sitúa la regleta (4) portadora de la correspondiente alineación de LEDs (5), uniformemente distribuidos a lo largo de la misma, y de manera también que los LEDs (5) quedan desenfrentados con respecto al borde de la placa (1), como se observa en la figura 2.In view of the figures outlined you can observe how the panelable structure materializes on a plate transparent (1), preferably methacrylate, mounted on a support frame (2), provided with a groove (3) sharply oversized with respect to the thickness of the plate (1), so that at the bottom of said groove (3) is the strip (4) carrier of the corresponding alignment of LEDs (5), evenly distributed throughout it, and so also that the LEDs (5) are disengaged with respect to the edge of the plate (1), as seen in Figure 2.

En una segunda acanaladura (6) del marco soporte (2) se aloja a su vez la zona marginal y correspondiente de la lámina (7) portadora de las imágenes a iluminar y visualizar.In a second groove (6) of the support frame (2) the marginal and corresponding zone of the sheet (7) carrier of the images to be illuminated and visualized.

Tal como anteriormente se ha dicho, la anchura de la acanaladura (3) es considerablemente mayor que el espesor de la placa de metacrilato (1), de manera que la alineación de LEDs (5) queda situada en posición desplazada con respecto a dicha placa (1), o lo que es lo mismo, de manera que la luz emitida por dichos LEDs (5) se difunde a lo largo y ancho de una cámara (8) establecida entre la placa de metacrilato (1) y la lámina (7) portadora del diseño.As previously stated, the width of the groove (3) is considerably greater than the thickness of the methacrylate plate (1), so that the alignment of LEDs (5) it is located in a displaced position with respect to said plate (1), or what is the same, so that the light emitted by said LEDs (5) diffuses throughout an established camera (8) between the methacrylate plate (1) and the sheet (7) carrying the design.

La cara interna (9) de la placa de metacrilato (1) está afectada por una pluralidad de protuberancias (9) de reducidas dimensiones, con la planta tendente al cuadrado preferentemente, aunque cualquier otra forma geométrica sería igualmente válida, como muestra la figura 3, con una distribución al tresbolillo y con un alto grado de densidad, con la especial particularidad de que el espesor de tales protuberancias crece progresivamente de la zona marginal de la placa (1) próxima a los LEDs (5), hacia la zona opuesta de la estructura, concretamente hacia el borde opuesto del marco cuando en éste último no existan LEDs; o hacia el centro de la estructura cuando si existan LEDS en el otro borde.The inner face (9) of the methacrylate plate (1) is affected by a plurality of protuberances (9) of small dimensions, with the plant tended to square preferably, although any other geometric shape would be equally valid, as shown in Figure 3, with a distribution to Tresbolillo and with a high degree of density, with the special particularity that the thickness of such bumps grows progressively of the marginal zone of the plate (1) next to the LEDs (5), towards the opposite area of the structure, specifically towards the opposite edge of the frame when the latter does not exist LEDs; or towards the center of the structure when there are LEDS in The other edge.

Aunque las protuberancias (10) pueden ser obtenidas por cualquier medio, preferentemente se tratará de puntos realizados por impresión digital, concretamente por el dispositivo "UVI", (lámpara de luz solar), en el material constitutivo de la placa (1), con un secado instantáneo.Although the bumps (10) can be obtained by any means, preferably it will be points made by digital printing, specifically by the device "UVI", (solar light lamp), in the constituent material of the plate (1), with instant drying.
