Con referencia concreta a las Figuras citadas, mediante la referencia numérica 10 se indica, como un conjunto, una vista esquemática del sistema portador de luz para luz natural según la presente invención.With specific reference to the cited Figures, by numerical reference 10 a set is indicated as a schematic view of the light carrier system for natural light according to The present invention.
El sistema portador de luz para luz natural 10 se da a conocer, en primer lugar, provisto de un sensor de luz solar 11, equipado con una lente Fresnel 12, constituida por una película y con concentración lineal, un conducto de transporte 13 y un difusor 14.The light carrier system for natural light 10 it is disclosed, first of all, provided with a light sensor solar 11, equipped with a Fresnel 12 lens, consisting of a film and with linear concentration, a transport duct 13 and a diffuser 14.
La lente Fresnel 12 está situada sobre la superficie cilíndrica del sensor de luz solar 11.The Fresnel 12 lens is located on the cylindrical surface of the solar light sensor 11.
El sensor de luz solar 11 está situado en la parte exterior del edificio, en el que está aplicado el sistema portador de luz, para uso con luz natural 10, mientras que el difusor 14 está instalado dentro del edificio, en el extremo del conducto de transporte 13.The solar light sensor 11 is located in the outside of the building, in which the system is applied light carrier, for use with natural light 10, while the diffuser 14 is installed inside the building, at the end of the transport duct 13.
El difusor 14 es una estructura en forma de caja que presenta la misma anchura que el conducto de transporte 13 (ilustrado esquemáticamente en las Figuras adjuntas), mientras que la profundidad varía según las medidas del recinto en el que está instalado el sistema portador de luz, para uso con luz natural 10.The diffuser 14 is a box-shaped structure having the same width as the transport duct 13 (schematically illustrated in the attached Figures), while the depth varies according to the measurements of the enclosure in which it is installed the light carrier system, for use with natural light 10.
Dentro de la unidad constituida por el conducto de transporte 13 y el difusor 14, un reflector de aluminio se curva desde el conducto de transporte hasta la base del difusor 14, tocando la superficie inferior constituida por una OLF (Optical Lighting Film - Película de Iluminación Óptica) que se apoya sobre una lámina de policarbonato de opalina, que representa la superficie de emisión.Within the unit constituted by the conduit transport 13 and diffuser 14, an aluminum reflector bends from the transport duct to the base of the diffuser 14, touching the bottom surface consisting of an OLF (Optical Lighting Film - Optical Lighting Film) that rests on a sheet of opaline polycarbonate, which represents the emission surface.
El sensor de luz solar 11 es un sistema activo, capaz de seguir el curso del sol, siguiendo la altura sobre el horizonte, durante el día, para aprovechar al máximo las capacidades de recepción del sistema.The solar light sensor 11 is an active system, able to follow the course of the sun, following the height above the horizon, during the day, to take full advantage of the capabilities of system reception.
Este resultado se obtiene mediante servomecanismos (accionadores eléctricos), controlados por sensores y microordenadores, que permiten al sensor de luz solar 11, situado fuera del edificio, girar verticalmente desde la parte superior a la parte inferior y viceversa, siguiendo la altura del sol sobre el horizonte por medio de un PLC, que controla un motor paso a paso (no representado para mayor simplicidad).This result is obtained by servomechanisms (electric actuators), controlled by sensors and microcomputers, which allow the solar light sensor 11, located outside the building, turn vertically from the top to the bottom and vice versa, following the height of the sun over the horizon by means of a PLC, which controls a stepper motor (not represented for simplicity).
Más concretamente, la Figura 1 ilustra el sensor de luz solar 11, con una lente Fresnel 12 y la entrada del conducto de transporte 13; siendo también visibles dos paredes laterales transparentes 24 y 25 y una pared posterior trasparente 26, además de una pared frontal no trasparente 27 provista, en su interior, de un elemento reflectante, completando todos estos elementos la estructura del sensor de luz solar 11.More specifically, Figure 1 illustrates the sensor of sunlight 11, with a Fresnel 12 lens and duct inlet transport 13; two side walls are also visible transparent 24 and 25 and a transparent rear wall 26, in addition of a non-transparent front wall 27 provided, inside, with a reflective element, completing all these elements the solar light sensor structure 11.
Además, se puede observar que el cuerpo del sensor de luz solar 11 es susceptible de hacerse girar por medio de una palanca 20 activada por el pistón 21.In addition, it can be seen that the body of the solar light sensor 11 is capable of being rotated by means of a lever 20 activated by the piston 21.
El punto focal está aproximadamente a 40 cm de distancia desde la superficie inferior de la lente (que es también la profundidad del sensor de luz solar) 11, donde está situado el conducto de transporte 13, recubierto, a su vez, por un material muy reflectante, y constituido por un componente en forma de caja, de 180 cm de anchura y 10 cm de altura, con una profundidad variable según el espesor de la pared en la que está empotrado.The focal point is approximately 40 cm from distance from the bottom surface of the lens (which is also the depth of the solar light sensor) 11, where the transport duct 13, coated, in turn, with a material very reflective, and constituted by a box-shaped component, 180 cm wide and 10 cm high, with a depth variable according to the thickness of the wall in which it is embedded.
Las lentes de película Fresnel 12 están constituidas por una película prismática en la que la inclinación de los microprismas, dispuestos en el material, varía gradualmente a medida que se alejan del punto central.Fresnel 12 film lenses are constituted by a prismatic film in which the inclination of the microprisms, arranged in the material, varies gradually to as they move away from the center point.
Como se indicó anteriormente, la lente Fresnel 12 está situada sobre la superficie cilíndrica del sensor de luz solar 11.As indicated above, the Fresnel lens 12 is located on the cylindrical surface of the light sensor solar 11.
Con esta estructura de la lente 12, el resultado obtenido es el de una lente que sigue completamente las reglas de la geometría óptica, pero que presenta el espesor de una película (aproximadamente 0,5 mm).With this structure of lens 12, the result obtained is that of a lens that completely follows the rules of optical geometry, but that presents the thickness of a film (approximately 0.5 mm).
De este modo, la lente Fresnel 12 puede producir un flujo laminar muy concentrado, aumentando así el rendimiento del sistema, con un coeficiente de transmisión poco inferior al 100%, de modo que existen muy pocas pérdidas debido a la absorción.In this way, the Fresnel 12 lens can produce a highly concentrated laminar flow, thus increasing the yield of system, with a transmission coefficient slightly less than 100%, of so there are very few losses due to absorption.
La Figura 4 ilustra una vista esquemática del sistema portador de luz, para uso con luz natural 10, en un modo de funcionamiento en el que la luz que procede del exterior no es suficiente para la iluminación interna.Figure 4 illustrates a schematic view of the light carrier system, for use with natural light 10, in a mode of operation in which the light that comes from outside is not Enough for internal lighting.
En este modo, se enciende una batería de lámparas 23 y su luz es reflejada por un espejo 22 y transportada al interior del difusor 14.In this mode, a battery of lamps 23 and their light is reflected by a mirror 22 and transported inside the diffuser 14.
Sin embargo, en el caso de que la luz exterior sea suficiente, se apagan las lámparas 23 y se hace girar el espejo 22 para dejar libre el conducto de transporte 13.However, in the event that the exterior light be enough, the lamps 23 go out and the mirror is rotated 22 to free the transport duct 13.
Las características del sistema portador de luz para luz natural contemplado en la presente invención y las ventajas de este sistema resaltarán evidentes a partir de la descripción.The characteristics of the light carrier system for natural light contemplated in the present invention and the advantages of this system will be evident from the description.
En particular, se observa el número reducido de componentes del sistema; este hecho tiene influencias positivas sobre su gestión y mantenimiento a largo plazo.In particular, the reduced number of System Components; this fact has positive influences about its management and long-term maintenance.
El impacto dimensional en la sección de aproximadamente 25 cm de altura es considerablemente más pequeño en relación con los tipos de sensores de luz solar pasivos de la técnica anterior. De hecho, estos sensores de luz solar requieren una sección con dimensiones totales, que varían desde un mínimo de 30 a 40 cm a un máximo de 50 a 60 cm, con influencias negativas sobre la gestión volumétrica estructural del edificio y la integración del sistema con redes de disposiciones en plantas.The dimensional impact on the section of approximately 25 cm tall is considerably smaller in relationship with the types of passive solar light sensors of the prior art In fact, these solar light sensors require a section with total dimensions, which vary from a minimum of 30 to 40 cm to a maximum of 50 to 60 cm, with negative influences on the structural volumetric management of the building and the system integration with networks of arrangements in plants.
Resulta evidente que el instrumento con estas dimensiones reducidas es similar a la altura de los instrumentos de iluminación convencionales, que pueden o no estar perfectamente empotrados en sistemas de falso techo.It is clear that the instrument with these reduced dimensions is similar to the height of the instruments conventional lighting, which may or may not be perfectly embedded in false ceiling systems.
Por último, resulta evidente que se pueden realizar numerosas variaciones en el sistema portador de luz para luz natural contemplado en la presente invención, sin apartarse por ello de la novedad intrínseca de la invención.Finally, it is clear that you can make numerous variations in the light carrier system to natural light contemplated in the present invention, without departing from that of the intrinsic novelty of the invention.
En la forma de realización práctica de la invención, los materiales, las formas y las dimensiones de los detalles ilustrados pueden variar según los requisitos y éstos pueden sustituirse por otros de equivalencia técnica.In the practical embodiment of the invention, materials, shapes and dimensions of Illustrated details may vary according to the requirements and these they can be replaced by others of technical equivalence.
