Description
Sistema de representación de imágenes.Image representation system.
La presente invención se refiere a un sistema de representación de imágenes que comprende una pantalla de retroproyección adosada a una capa transparente que es eficaz con cualquier nivel de iluminación.The present invention relates to a system of representation of images comprising a screen of rear projection attached to a transparent layer that is effective with Any level of lighting.
Son conocidos los sistemas de retroproyección de publicidad en superficies transparentes de escaparates consistentes en una pantalla de retroproyección adosada a dicha superficie por el lado interior sobre la cual se proyectan imágenes desde un proyector dispuesto en el interior del local, de tal modo que la imagen publicitaria se ve desde el exterior.Rear projection systems are known for display on transparent surfaces of shop windows consisting of a rear projection screen attached to said surface on the inner side on which images are projected from a projector arranged inside the premises, thereby that the advertising image is seen from the outside.
Estos sistemas de retroproyección presentan el inconveniente de que, cuando es de día, la intensidad de la luz incidente desde el exterior reflejada por la superficie exterior de la superficie transparente es mucho mayor que la intensidad de la luz proveniente del proyector transmitida por la pantalla, de tal modo que no se distinguen bien las imágenes proyectadas, quedando inutilizada para publicidad, cuando es de día, la zona del escaparate cubierta por la pantalla de retroproyección.These overhead projection systems present the inconvenient that, when it is day, the intensity of the light incident from the outside reflected by the outer surface of the transparent surface is much greater than the intensity of the light from the projector transmitted by the screen, such so that the projected images are not well distinguished, leaving unused for advertising, when it is day, the area of Showcase covered by the rear projection screen.
Una solución a este inconveniente es utilizar proyectores de gran potencia lumínica. Sin embargo, estos proyectores tienen un coste elevado, tanto inicial como de operación, además de presentar, por sus dimensiones y peso, dificultades desde el punto de vista de su integración en un entorno de trabajo como puede ser una oficina.One solution to this problem is to use projectors of great light power. However, these projectors have a high cost, both initial and operation, in addition to presenting, due to its size and weight, difficulties from the point of view of its integration into a Work environment such as an office.
Una alternativa es utilizar proyectores de prestaciones medias y utilizarlos únicamente en horas de bajo nivel de iluminación, provocando que de día o con altos niveles de iluminación exterior, el escaparate presenta una zona oscura, poco estética e inútil desde el punto de vista publicitario.An alternative is to use projectors of medium performance and use them only at low level hours of lighting, causing that by day or with high levels of exterior lighting, the showcase presents a dark area, little aesthetic and useless from an advertising point of view.
Otra solución más a este inconveniente es prescindir de la técnica de publicidad por proyección de imágenes utilizando publicidad estática que se adhiere a la superficie transparente.Another solution to this problem is dispense with the technique of image projection advertising using static advertising that adheres to the surface transparent.
Esta otra solución carece de la versatilidad que ofrece el sistema por proyección y además presenta el inconveniente de que en ausencia de luz carece de vistosidad.This other solution lacks the versatility that offers the system by projection and also presents the inconvenient that in the absence of light it lacks sight.
Por lo tanto, es evidente la necesidad de disponer de un sistema de representación de imágenes para escaparates que evite los inconvenientes mencionados, es decir, que permita utilizar la superficie del escaparate para representar imágenes tanto de día como de noche.Therefore, the need for have an image representation system to shop windows that avoid the aforementioned inconveniences, that is, allow to use the showcase surface to represent images both day and night.
Con el sistema de representación de imágenes se resuelven los inconvenientes citados, presentando otras ventajas que se describirán a continuación.With the image representation system you solve the aforementioned problems, presenting other advantages which will be described below.

La figura 1 es una vista en sección del sistema en la que se puede apreciar la disposición relativa de los elementos.Figure 1 is a sectional view of the system in which the relative disposition of the elements.
La figura 2 es un diagrama esquemático de los balances de radiación lumínica en horas de baja intensidad lumínica.Figure 2 is a schematic diagram of the light radiation balances in low intensity hours light.
La figura 3 es un diagrama esquemático de los balances de radiación lumínica en horas de elevada intensidad lumínica.Figure 3 is a schematic diagram of the light radiation balances during high intensity hours light.
Según una realización preferida, tal como se puede apreciar en la figura 1, el sistema de representación de imágenes objeto de la invención comprende una capa transparente 1, una pantalla de proyección 2 adosada a un lado dicha capa 1 y un proyector 3, separando dichas capa 1 y pantalla 2 un espacio interior 4 de un espacio exterior 5, y un cartel microperforado 6 adosado a dicha capa 1 por el lado exterior.According to a preferred embodiment, as is you can see in figure 1, the system of representation of Images object of the invention comprises a transparent layer 1, a projection screen 2 attached to said side 1 and a projector 3, separating said layer 1 and screen 2 a space interior 4 of an exterior space 5, and a microperforated poster 6 attached to said layer 1 on the outer side.
El funcionamiento de dicho sistema se aprecia en la figura 2, cuando se utiliza de noche, y en la figura 3, cuando se utiliza de día.The operation of this system can be seen in Figure 2, when used at night, and in Figure 3, when It is used by day.
En las figuras 2 y 3, debe entenderse que la anchura de las flechas representan de manera orientativa intensidades relativas de radiación lumínica.In Figures 2 and 3, it should be understood that the width of the arrows represent indicatively relative intensities of light radiation.
Así, tal como se aprecia en la figura 2, en horas de bajo nivel de iluminación, una fracción considerable 7 de la intensidad lumínica proyectada 8 por el proyector es transmitida por la pantalla 2, el cristal 1 y el cartel 6 de manera que la imagen puede ser observada por un observador 9. Al mismo tiempo, una fracción de 11 de la luz proveniente del exterior 10 es reflejada por el cartel 6, de manera que también alcanza al observador 9.Thus, as seen in Figure 2, in low lighting hours, a considerable fraction 7 of the projected light intensity 8 by the projector is transmitted on screen 2, glass 1 and poster 6 so that the image can be observed by an observer 9. At the same time, a fraction of 11 of the light coming from outside 10 is reflected by poster 6, so that it also reaches the observer 9.
Ahora bien, en el sistema de representación de la invención la transmitancia de la pantalla 2 y la absorbancia del cartel 6 están escogidos de manera que la intensidad 7 sea mucho mayor que la intensidad 11, permitiendo que el observador 9 discrimine la imagen del cartel microperforado 6 y observe únicamente la imagen proyectada por el proyector 3.Now, in the representation system of the invention the transmittance of the screen 2 and the absorbance of poster 6 are chosen so that intensity 7 is much higher than intensity 11, allowing observer 9 discriminate the image of the microperforated poster 6 and observe only the image projected by the projector 3.
En cambio, tal como se aprecia en la figura 3, en horas de elevada iluminación, por ejemplo de día, el proyector está apagado y la fracción de luz reflejada 11 es mucho mayor, de tal manera que el observador 9 puede ver la imagen contenida en el cartel microperforado 6.Instead, as seen in Figure 3, during hours of high lighting, for example during the day, the projector is off and the fraction of reflected light 11 is much larger, than such that the observer 9 can see the image contained in the microperforated poster 6.
Además, de día, la pantalla 2 proporciona un mejor contraste del cartel microperforado 6 al evitar la transmisión de luz ambiental proveniente del interior 4 del local.In addition, by day, screen 2 provides a better contrast of the microperforated poster 6 by avoiding the ambient light transmission from inside 4 of the local.
En una segunda realización preferida, el sistema puede incluir un film adhesivo con tecnología interactiva sensible a presiones ejercidas por el lado exterior 5 dispuesto entre la pantalla de retroproyección 2 y la capa transparente 1, de tal manera que el observador pueda seleccionar la información que desee.In a second preferred embodiment, the system can include an adhesive film with sensitive interactive technology at pressures exerted by the outer side 5 disposed between the overhead projection screen 2 and the transparent layer 1, of such so that the observer can select the information that wish.
Con este dispositivo se consigue que el área de escaparate disponible sea útil las 24 horas del día, haciendo óptimo su uso, al mostrar imágenes estáticas con un contraste elevado en horas de elevado nivel de iluminación e imágenes dinámicas durante las horas de bajo nivel de iluminación.With this device the area of Showcase available be useful 24 hours a day, making optimal use, when displaying static images with a contrast high in hours of high level of lighting and images dynamics during low lighting hours.
