Abstract

The invention relates to an optical system for transporting natural light into a building, formed by a hollow guide (3) having a peripheral layer formed by two types of prismatic plastic sheets performing guiding and extraction functions, without additional geometric elements. The light guiding sheet (30) is such that the edges of the prisms face outwards and are parallel to the longitudinal axis of the guide, and the sheet (40) that performs the extraction functions is such that the edges of the prisms face outwards and are parallel to the longitudinal axis of the guide. The amount of light extracted in a determined position of the guide can be regulated by means of the increase or decrease in the area of the extraction sheet.

Declaraci6n motivada segun los articulos 29. y 29.7 del Reglamento de ejecuci6n de la Ley 11/198 , de 20 de marzo, de Patentes sobre la novedad y la actividad inventiva; citas y explicaciones en apoyo de esta declaraci6n  2. Statement motivated according to articles 29. and 29.7 of the Regulations for the execution of Law 11/198, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement Se considera D01 el documento del estado de la tecnica mas pr6ximo al objeto de la solicitud reivindicado. Siguiendo la redacci6n de la reivindicaci6n independiente, D01 describe lo siguiente: Sistema de iluminaci6n por guiado 6ptico y extractor de luz (ver columna 2, lineas de la 29 a la 38) que, en sus diversas realizaciones posibles comprende, entre otros, los siguientes elementos tecnicos: D01 is considered the state of the art document closest to the object of the claimed application. Following the wording of the independent claim, D01 describes the following: Optical guidance and light extractor lighting system (see column 2, lines 29 to 38) which, in their various Possible embodiments include, among others, the following technical elements:
--
Sistema de iluminaci6n artificial constituido por una bombilla (ver referencia 11 en figura 1)  Artificial lighting system consisting of a bulb (see reference 11 in figure 1)
--
Guia de luz compuesta por dos laminas prismaticas con propiedades 6pticas. Las caras que presentan los prismas se encuentran en contacto entre si formando el eje de los prismas un angulo preferiblemente de 90O y conformando una superficie tubular hueca y lisa en sus caras interna y externa. El eje de los prismas de la lamina mas interna es paralelo al eje de la guia de luz. La cresta de los prismas de la lamina mas externa se extiende circunferencialmente en torno al eje de la guia de luz. Ver columna 8, lineas de la 37 a la 54 y figuras 15 y 16. Light guide composed of two prismatic sheets with optical properties. The faces presented by the prisms are in contact with each other, forming the axis of the prisms preferably at an angle of 90O and forming a hollow and smooth tubular surface on its inner and outer faces. The axis of the prisms of the innermost lamina is parallel to the axis of the light guide. The crest of the prisms of the outermost sheet extends circumferentially around the axis of the light guide. See column 8, lines 37 through 54 and figures 15 and 16.
--
Elementos direccionadores de la luz compuestos por reflectores que pivotan sobre uno de sus ejes (ver columna 7, lineas de la 6 a la 15 y figura 8). Light-conducting elements composed of reflectors that pivot on one of its axes (see column 7, lines 6 through 15 and figure 8).
--
Un cierre en la parte inferior y un cierre en la parte superior (ver columna 6, lineas de la 64 a la 67, columna 7, lineas de la 1 a la 5 y columna 5, lineas de la 42 a la 45). En relaci6n a la reivindicaci6n independiente numero 1, y teniendo en cuenta el contenido del documento D01, se concluye que la principal diferencia entre R1 y D01 consiste en que, en R1 se hace referencia a un sistema de iluminaci6n natural (por lo que es necesario disponer de un sistema de captaci6n de la luz del sol y de un elemento randomizador) mientras que, en D01, se hace referencia a un sistema de iluminaci6n artificial por lo que en D01 se hace referencia a la existencia de una bombilla como sistema de iluminaci6n y se prescinde del sistema de captaci6n por ser innecesario en este caso. En este sentido, se recomienda la lectura del documento D02 perteneciente al mismo sector tecnico que describe un sistema de iluminaci6n natural por guiado 6ptico y extracci6n de luz aplicado a la edificaci6n que incorpora un elemento de captaci6n y un elemento randomizador (ver resumen y figura 6). Por tanto, a la vista del contenido de los documentos D01 y D02, elexperto en lamateriapodria considerar que la combinaci6n de todas las caracteristicas tecnicas establecidas en R1 es un proceso normal de disefo que no implica ningun grado de actividad inventiva y, por tanto, no cumple el criterio establecido en el 8.1 de la Ley de Patentes. Por lo que respecta a las reivindicaciones dependientes 2, 3, 4 y 5 se considera que estas carecen de actividad inventiva del mismo modo que la reivindicaci6n independiente de la cual dependen puesto que los elementos tecnicos en ellas incluidos se encuentran asi mismo descritos en D01 y D02. En relaci6n a la reivindicaci6n dependiente numero 6, se considera que la configuraci6n de la lamina de guiado y la lamina de extracci6n en un panel tipo sandwich es una opci6n de disefo que no implica un grado de actividad inventiva para el experto en la materia. En este sentido, se recomienda la lectura del documento D03 que incorpora una estructura de sandwich en la regi6n de salida de la luz de un sistema de iluminaci6n por leds (ver resumen y figura 2). Por lo que respecta a la reivindicaci6n dependiente numero 7, la incorporaci6n en la parte central de una lamina perimetral con prismas de guiado simetricos respecto de la del exterior y formando otra guia de luz se considera una ligera variante constructiva que el experto en la materia consideraria sin la aplicaci6n de ningun grado de actividad inventiva especialmente teniendo en cuenta que las ventajas conseguidas se preven facilmente: ampliar las posibilidades de extracci6n de luz. En este sentido, se recomienda la lectura del documento D04 que describe una guia de luzformada por diversas capasde material 6ptico dispuestas de manera concentrica. A closure at the bottom and a closure at the top (see column 6, lines 64 to 67, column 7, lines 1 to 5 and column 5, lines 42 to 45). In relation to independent claim number 1, and taking into account the content of document D01, it is concluded that the main difference between R1 and D01 is that, in R1 reference is made to a natural lighting system (so it is necessary have a system for capturing sunlight and a randomizing element) while, in D01, reference is made to an artificial lighting system, so in D01 reference is made to the existence of a light bulb as a lighting system and the collection system is dispensed with as unnecessary in this case. In this sense, it is recommended to read document D02 belonging to the same technical sector that describes a natural lighting system by optical guidance and light extraction applied to the building that incorporates a pickup element and a randomizing element (see summary and figure 6 ). Therefore, in view of the contents of documents D01 and D02, the expert in the field could consider that the combination of all the technical characteristics established in R1 is a normal design process that does not imply any degree of inventive activity and, therefore, does not meets the criteria established in 8.1 of the Patent Law. As regards dependent claims 2, 3, 4 and 5, it is considered that they lack inventive activity in the same way as the independent claim on which they depend since the technical elements included therein are also described in D01 and D02. In relation to dependent claim number 6, it is considered that the configuration of the guiding sheet and the extraction sheet in a sandwich panel is a design option that does not imply a degree of inventive activity for the person skilled in the art. In this regard, reading of document D03 incorporating a sandwich structure in the light output region of a LED lighting system is recommended (see summary and figure 2). With regard to the dependent claim number 7, the incorporation in the central part of a perimeter sheet with symmetrical guiding prisms with respect to the exterior and forming another light guide is considered a slight constructive variant that the person skilled in the art would consider without the application of any degree of inventive activity especially taking into account that the advantages achieved are easily foreseen: to expand the possibilities of extracting light. In this sense, it is recommended to read document D04 which describes a light guide formed by various layers of optical material arranged concentrically.
