Description

Panel luminoso, perfeccionado.Luminous panel, perfected.

La presente invención está destinada a dar a conocer un panel luminoso, perfeccionado, que aporta sensibles características de novedad y de actividad inventiva con respecto a lo actualmente conocido.The present invention is intended to give know a luminous panel, perfected, which provides sensitive characteristics of novelty and inventive activity with respect to the currently known.

El panel luminoso objeto de la presente invención es del tipo plano, con medios luminosos internos, destinado a aplicaciones publicitarias y de otro tipo, presentando interiormente focos luminosos tal como tubos fluorescentes y un motivo publicitario superpuesto a una pantalla transparente o traslúcida para permitir su visualización.The luminous panel object of the present invention is of the flat type, with internal light means, intended for advertising and other applications, presenting internally light bulbs such as fluorescent tubes and a advertising motif superimposed on a transparent screen or translucent to allow viewing.

Un problema que presentan los paneles de iluminación dotados de tubos fluorescentes internos es el de la irregularidad de iluminación producida por la diferente intensidad de iluminación que producen los tubos fluorescentes sobre la pantalla intermedia y finalmente sobre el motivo publicitario o de otro tipo que se desea iluminar. En efecto, los tubos fluorescentes tienen una disposición lineal de manera que la máxima intensidad luminosa coincide con el eje que pasando por el tubo fluorescente es perpendicular a la pantalla, mientras que para las demás zonas la intensidad luminosa va disminuyendo. Ello se traduce en un efecto marcado de franjas en una placa traslúcida colocada delante de los tubos fluorescentes, dando lugar a un desagradable efecto de irregularidad de iluminación.A problem with the panels of lighting equipped with internal fluorescent tubes is that of the lighting irregularity produced by the different intensity of lighting produced by fluorescent tubes on the intermediate screen and finally on the advertising or another type that you want to light up. In effect, fluorescent tubes they have a linear arrangement so that the maximum intensity luminous coincides with the axis that passes through the fluorescent tube It is perpendicular to the screen, while for other areas the light intensity is decreasing. This translates into a marked effect of stripes on a translucent plate placed in front of the fluorescent tubes, giving rise to an unpleasant effect of irregularity of lighting.

Para solucionar el problema indicado la presente invención prevé la constitución de un deflector a disponer entre los tubos fluorescentes de iluminación y la pantalla frontal del panel luminoso, que está dotado de zonas de trama de puntos o líneas de densidad variable desde la parte que corresponde al frontal de los tubos fluorescentes hasta la zona intermedia entre cada dos de dichos tubos fluorescentes, de manera que la mayor densidad de la trama y por lo tanto, la mayor opacidad corresponde a la parte frontal opuesta a cada uno de los tubos y dicha trama se va difuminando o aligerando progresivamente desde dicha parte central hasta las zonas de separación entre cada dos tubos. La densidad de la trama y, por lo tanto, el efecto de opacidad producido es continuamente variable desde dicha zona coincidente con el tubo hasta las zonas intermedias entre cada dos tubos, de manera que dicha densidad de trama u opacidad es inversamente proporcional a la intensidad de iluminación producida por el tubo sobre la pantalla, compensando por lo tanto la intensidad de iluminación variable producida por los tubos y dando lugar a una iluminación regular y constante del panel.To solve the problem indicated here The invention provides for the constitution of a baffle to be arranged between fluorescent lighting tubes and front panel display luminous, which is equipped with plot areas of points or lines of variable density from the part corresponding to the front of the fluorescent tubes to the intermediate zone between every two of said fluorescent tubes, so that the highest density of the plot and therefore, the highest opacity corresponds to the part front opposite to each of the tubes and said frame goes blurring or lightening progressively from said central part to the separation zones between every two tubes. The density of the plot and, therefore, the opacity effect produced is continuously variable from said area coinciding with the tube to the intermediate zones between every two tubes, so that said weft density or opacity is inversely proportional to the intensity of illumination produced by the tube on the screen, therefore compensating the lighting intensity variable produced by the tubes and giving rise to lighting regular and constant panel.

La opacidad, creada por tramado de líneas o puntos, combinación de los mismos u otras pequeñas figuras u otros medios, se podrá realizar por cualesquiera métodos conocidos, dando lugar a un sombreado cuya característica esencial es su distribución simétrica desde la parte coincidente con el frontal de cada tubo hacia los lados y que proporciona una densidad de la opacidad inversamente proporcional a la intensidad luminosa producida por el tubo, compensando de esta manera la irregularidad de iluminación.The opacity, created by dithering lines or points, combination thereof or other small figures or others means, may be performed by any known methods, giving place to a shader whose essential characteristic is its symmetric distribution from the part coinciding with the front of each tube sideways and that provides a density of the opacity inversely proportional to light intensity produced by the tube, thus compensating for irregularity of lighting.

La figura 1 muestra una vista en perspectiva de un panel de iluminación realizado de acuerdo con la presente invención, con sus componentes desmontados.Figure 1 shows a perspective view of a lighting panel made in accordance with this invention, with its components disassembled.

La figura 2 muestra una vista en alzado frontal.Figure 2 shows an elevation view frontal.

Las figuras 3 y 4 muestran sendas secciones según un eje longitudinal y según un eje transversal del propio panel luminoso.Figures 3 and 4 show sections according to a longitudinal axis and along a transverse axis of the panel itself bright.

La figura 5 muestra esquemáticamente una forma esquemática de sombreado con opacidad variable.Figure 5 schematically shows a shape Schematic shading with variable opacity.

La figura 6 muestra la disposición mencionada de dos ejemplos de zonas de opacidad variable en un difusor según la presente invención.Figure 6 shows the aforementioned provision of two examples of zones of variable opacity in a diffuser according to the present invention

Las figuras 7 y 8 muestran respectivamente secciones transversales parciales de un panel luminoso según la invención y según la técnica conocida.Figures 7 and 8 show respectively partial cross sections of a luminous panel according to the invention and according to the known technique.

De acuerdo con las figuras, el panel luminoso objeto de la presente invención comporta un armazón (1) dotado convencionalmente de focos de iluminación lineales, especialmente tubos fluorescentes (2), (2'), (2'')... en disposición paralela entre sí entre un borde superior y un borde inferior del armazón (1), por ejemplo, en disposición vertical, tal como es de ver en la figura 1. El panel objeto de la presente invención presenta de modo esencial un difusor (3) en disposición intermedia entre los tubos luminosos (2), (2'), (2'')... y una pantalla frontal (4), por ejemplo, traslúcida o de otro tipo, que será el soporte del motivo publicitario que se desea iluminar. El difusor (3) tiene como característica esencial el disponer de una serie de zonas (5), (5'), (5'')... dispuestas en correspondencia con los tubos luminosos (2), (2'), (2'')... y que presentan opacidad variable desde su eje central paralelo al tubo correspondiente hasta los bordes, formando zonas de estructura sensiblemente rectangular tal como se ha representado y tal como se puede apreciar en detalle en las figuras 5 y 6. Dichas zonas (5), (5'), (5'') se caracterizan por presentar opacidad máxima en su zona central (6), (6'), (6'') correspondiente al eje de los tubos sobre las que se encuentran superpuestas y reduciéndose dicha opacidad hacia los bordes que se han representando con las líneas de trazos (7) y (8) para la franja (6). La característica esencial del sombreado de dichas zonas es que su opacidad es inversamente proporcional a la iluminación recibida desde el tubo de manera que al compensar dicha iluminación variable el efecto luminoso del panel, en la pantalla frontal (4) es el de iluminación uniforme.According to the figures, the luminous panel object of the present invention involves a frame (1) provided conventionally of linear lighting bulbs, especially fluorescent tubes (2), (2 '), (2' ') ... in parallel arrangement each other between an upper edge and a lower edge of the frame (1), for example, in vertical arrangement, as can be seen in the Figure 1. The panel object of the present invention presents  essential a diffuser (3) in intermediate arrangement between the tubes lights (2), (2 '), (2' ') ... and a front screen (4), for example, translucent or otherwise, which will support the motive advertising that you want to illuminate. The diffuser (3) has as essential feature of having a series of zones (5), (5 '),  (5``) ... arranged in correspondence with the light tubes (2), (2 '), (2' ') ... and that have variable opacity from their axis central parallel to the corresponding tube to the edges, forming areas of substantially rectangular structure as it has been represented and as can be seen in detail in the figures 5 and 6. Said zones (5), (5 '), (5' ') are characterized by presenting maximum opacity in its central zone (6), (6 '), (6' ') corresponding to the axis of the tubes on which they are superimposed and reducing said opacity towards the edges that have representing with the dashed lines (7) and (8) for the strip (6). The essential characteristic of shading of these areas is that its opacity is inversely proportional to the lighting received from the tube so that by compensating said lighting variable the light effect of the panel, on the front screen (4) It is the one of uniform illumination.

La forma de conseguir dicha opacidad variable podrá obedecer a múltiples métodos conocidos en la técnica como por ejemplo, tramados de puntos o líneas u otras formas o combinación de las mismas obtenidos por serigrafía, pulverización, métodos fotográficos, etc.The way to achieve this variable opacity may obey multiple methods known in the art as per example, hatched of points or lines or other shapes or combinations of the same obtained by screen printing, spraying, methods photographic, etc.

Los bordes de cada una de las zonas (5), (5'), (5'')... que a efectos de mayor claridad se han representado con las líneas (7) y (8) para la zona o franja (5) serán en la práctica poco distinguibles puesto que existirá una difuminación suave y gradual entre la zona central (6) y las zonas de los bordes hasta llegar a las zonas intermedias (9) entre cada dos zonas de opacidad variable. Por lo tanto, en las realizaciones prácticas no se apreciarán en muchos casos las líneas (7) y (8).The edges of each of the zones (5), (5 '), (5 '') ... which for the sake of clarity have been represented with lines (7) and (8) for the zone or strip (5) will be in practice little distinguishable since there will be a soft blur and gradual between the central zone (6) and the edge areas up to reach the intermediate zones (9) between each two opacity zones variable. Therefore, in practical realizations it is not they will appreciate in many cases lines (7) and (8).

Otra característica de la presente invención es que tanto la parte superior como la parte inferior de las zonas de opacidad variable presentan zonas arqueadas tales como (10) y (11), figura 1, en las que no existe opacidad para adecuarse a la zona de la conexión del tubo fluorescente en la que, al ser la iluminación mínima, no es necesario dicho efecto de opacidad del difusor.Another feature of the present invention is that both the top and bottom of the areas of variable opacity have arcuate areas such as (10) and (11), Figure 1, in which there is no opacity to adapt to the area of the connection of the fluorescent tube in which, being the lighting minimum, this diffuser opacity effect is not necessary.

En los ejemplos mostrados esquemáticamente en las figuras 7 y 8 se observa que en el caso representado en la figura 7, que corresponde a una aplicación de la invención, los tubos fluorescentes (12) y (13) producen una iluminación variable sobre el difusor (14), tal como es de observar por la distribución de rayos luminosos, mientras que después de atravesar el difusor la iluminación es regular tal como se observa por los rayos luminosos que se han representado de manera uniforme (15), (15'), (15'').In the examples shown schematically in Figures 7 and 8 show that in the case represented in the Figure 7, which corresponds to an application of the invention, the fluorescent tubes (12) and (13) produce variable illumination on the diffuser (14), as observed by the distribution of light rays, while after passing through the diffuser the  lighting is regular as seen by light rays which have been represented uniformly (15), (15 '), (15' ').

Por el contrario, en un panel luminoso convencional, tal como se ha representado en la figura 8, los tubos (16) y (17) producen una iluminación tal que en la parte central de la pantalla (18) la iluminación es de mayor intensidad tal como se observa mediante los rayos (19) y (20), mientras que en las zonas laterales los rayos de luz (21) y (22) son más débiles y, por lo tanto, producen un efecto de iluminación irregular de la pantalla (18).On the contrary, in a luminous panel conventional, as shown in Figure 8, the tubes (16) and (17) produce lighting such that in the central part of the display (18) the lighting is of greater intensity as it is observe through rays (19) and (20), while in the zones lateral rays of light (21) and (22) are weaker and, therefore both produce an irregular lighting effect of the screen (18).

Todo cuanto no afecte, altere, cambie o modifique la esencia del panel descrito, será variable a los efectos de la presente invención.Everything that does not affect, alter, change or modify the essence of the described panel, it will be variable at Effects of the present invention.
