siguiente: next:
La figura 1.-Muestra una vista en perfil de un cristal transparente/translúcido realizado de acuerdo con el objeto de la presente invención, en el que el mismo aparece en situación inoperante, que se corresponde con su carácter translúcido. Figure 1 shows a profile view of a transparent / translucent crystal made in accordance with the object of the present invention, in which it appears in an inoperative situation, which corresponds to its translucent character.
La figura 2.-Muestra una vista similar a la de la figura 1, pero en la que el cristal aparece en situación de trabajo, es decir, conectado eléctricamente a una fuente de tensión, situación en la que el cristal adopta un carácter transparente. Figure 2.- Shows a view similar to that of Figure 1, but in which the glass appears in a working situation, that is, electrically connected to a voltage source, a situation in which the glass adopts a transparent character.
Como se puede ver en las figuras referidas, el dispositivo de la invención está constituido a partir de una estructura multi-capa, tipo sándwich, en la que se definen dos capas extremas ( 1-1 '), de naturaleza transparente, las cuales pueden estar obtenidas en cristal, policarbonato, o cualquier polímero termoplástico lineal con alto grado de cristalinidad, y un núcleo a base de cristal líquido, concretamente de polímero (2) y polímeros de cristales líquidos (3), entre los que se establecen en correspondencia con su cara superior y su cara inferior, sendas capas conductoras eléctricas (4-4'), que disponen de sus propias conexiones eléctricas (5-5') milimétricas, y que se conectan a una fuente de tensión ( 6), con su correspondiente interruptor (7). As can be seen in the aforementioned figures, the device of the invention is constituted from a sandwich-type multi-layer structure, in which two extreme layers (1-1 '), of a transparent nature, are defined, which can be be obtained in glass, polycarbonate, or any linear thermoplastic polymer with a high degree of crystallinity, and a core based on liquid crystal, specifically polymer (2) and liquid crystal polymers (3), among which are established in correspondence with its upper face and its lower face, two electrical conductive layers (4-4 '), which have their own millimeter electrical connections (5-5'), and that connect to a voltage source (6), with their corresponding switch (7).
Las capas conductoras eléctricas (4-4') estarán obtenidas preferentemente a base de óxido de estaño e indio, de manera que, tal y como se puede observar en la figura 1, cuando las mismas no están alimentadas eléctricamente, las partículas de cristales líquidos (3) tienden a presentar una disposición desordenada, que permite el paso de la luz (8), provocando la dispersión de la misma, con lo que se consigue un efecto translúcido para el cristal. The electrical conductive layers (4-4 ') will preferably be obtained based on tin and indium oxide, so that, as can be seen in Figure 1, when they are not electrically fed, the liquid crystal particles (3) tend to present a disorderly arrangement, which allows the passage of light (8), causing the dispersion of it, thereby achieving a translucent effect for the crystal.
Por su parte, y de acuerdo ya con la figura 2, cuando se alimenta eléctricamente a dichas capas conductoras, la corriente induce a las partículas de cristales líquidos (3) a presentar una disposición ordenada, perpendicular a la superficie del cristal, lo que permite el paso de la luz, sin difracción de la misma, lo que hace que el cristal presente un carácter transparente. On the other hand, and according to Figure 2, when these conductive layers are electrically fed, the current induces the particles of liquid crystals (3) to present an ordered arrangement, perpendicular to the surface of the crystal, which allows the passage of light, without diffraction thereof, which makes the crystal present a transparent character.
El dispositivo así descrito será susceptible de incorporar capas adicionales de naturaleza transparente, tales como capas protectoras, adhesivas, etc, sin que ello afecte a la esencia de la invención. The device thus described will be capable of incorporating additional layers of a transparent nature, such as protective, adhesive layers, etc., without affecting the essence of the invention.
El conjunto del cristal estará rematado exteriormente por un marco, en el que se podrá integrar el interruptor (7), y del que emergerá el cable de alimentación para el dispositivo, si bien, en dicho marco podría integrarse igualmente una batería o grupo de baterías recargables. The glass assembly will be externally topped by a frame, in which the switch (7) can be integrated, and from which the power cable for the device will emerge, although, in that frame a battery or group of batteries could also be integrated rechargeable
El tiempo de ordenación/desordenación de las partículas de cristales líquidos (3) es sumamente rápido, pudiéndose cifrar del orden de 100 milisegundos para paso del estado translúcido al transparente, y de 400 milisegundos para paso del estado transparente al translúcido. The time of ordering / disorganization of the particles of liquid crystals (3) is extremely fast, being able to be encrypted in the order of 100 milliseconds for the transition from the translucent to the transparent state, and 400 milliseconds for the transition from the transparent to the translucent state.
El dispositivo descrito presenta una larga vida útil, del orden de 1 O años, pudiendo funcionar correctamente dentro de un amplio margen de temperaturas, desde -20°C hasta 60°C, con un reducido consumo eléctrico, un amplio ángulo de visión y una gran capacidad de transmisión de luz cuando el dispositivo se encuentra encendido. The described device has a long service life, of the order of 1 O years, being able to function correctly within a wide range of temperatures, from -20 ° C to 60 ° C, with a reduced power consumption, a wide viewing angle and a Great light transmission capacity when the device is on.
La especial estructuración del dispositivo hace que éste constituya 5 una barrera para los rayos ultravioleta, con un rango de bloqueo de los mismos que se puede cifrar por encima del98%. The special structuring of the device makes it a barrier for ultraviolet rays, with a blocking range that can be encrypted above 98%.
