CAMPO TÉCNICO DE LA INVENCIÓN TECHNICAL FIELD OF THE INVENTION
La presente invención se refiere a un guarnecido interior retroiluminado para vehículos con efecto luminoso brillante que comprende una tapa decorativa transparente capaz de proporcionar un efecto luminoso variable dependiendo del ángulo de visión del ocupante del vehículo en relación al guarnecido interior retroiluminado. The present invention relates to a backlit interior trim for vehicles with a bright luminous effect comprising a transparent decorative cover capable of providing a variable luminous effect depending on the viewing angle of the vehicle occupant in relation to the backlit interior trim.
ANTECEDENTES DE LA INVENCION Cada vez es más frecuente que los guarnecidos interiores de vehículos añadan funciones de iluminación a las ya existentes, con el objeto de aumentar el confort de los ocupantes del vehículo. En algunos casos, es interesante que la adición de dicha función de iluminación se lleve a cabo de tal forma que los componentes encargados de desempeñarla queden ocultos cuando la fuente de luz está apagada. Este tipo de guarnecidos interiores se denominan normalmente guarnecidos interiores retroiluminados. BACKGROUND OF THE INVENTION It is increasingly common for vehicle interior trim to add lighting functions to existing ones, in order to increase the comfort of vehicle occupants. In some cases, it is interesting that the addition of said lighting function is carried out in such a way that the components in charge of performing it are hidden when the light source is switched off. This type of interior trim is commonly referred to as backlit interior trim.
Para retroiluminar un guarnecido interior, es habitual el uso de guías de luz para transmitir y distribuir la luz que normalmente emiten fuentes de luz puntuales como son los LEDs. Las guías de luz son capaces de iluminar una extensa superficie de luz con un reducido consumo de energía. El conjunto formado por la guía de luz y el LED forma el dispositivo de iluminación. Otras fuentes de luz distribuida capaces de iluminar una superficie extensa pueden ser también paneles electroluminiscentes, o dispositivos OLED por ejemplo. To backlight an interior trim, it is common to use light guides to transmit and distribute the light normally emitted by point light sources such as LEDs. The light guides are capable of illuminating a large surface of light with low energy consumption. The combination of the light guide and the LED forms the lighting fixture. Other light sources Distributed devices capable of illuminating a large surface can also be electroluminescent panels, or OLED devices for example.
Con el objeto de ocultar el dispositivo de iluminación, el guarnecido interior de vehículo retroiluminado puede comprender diferentes tipos de recubrimientos decorativos dependiendo del tipo de guarnecido interior y/o del aspecto del mismo. In order to conceal the lighting device, the backlit vehicle interior trim may comprise different types of decorative skins depending on the type of interior trim and / or the appearance thereof.
Por ejemplo, una opción disponible es un panel decorativo traslúcido que comprende pigmentos capaces de difuminar la luz recibida con el objeto de homogeneizarla cuando la fuente de luz está activa, y al mismo tiempo permiten ocultar el dispositivo de iluminación cuando la fuente de luz está apagada. Dicho panel decorativo traslúcido se suele denominar panel decorativo lechoso. For example, an available option is a translucent decorative panel that includes pigments capable of diffusing the received light in order to homogenize it when the light source is active, and at the same time allow to hide the lighting device when the light source is off. . Such a translucent decorative panel is often referred to as a milky decorative panel.
Así, este tipo de paneles decorativos lechosos, permite proporcionar una iluminación homogénea a lo largo de toda la superficie retroiluminada de guarnecido interior cuando la fuente de luz está activa, sin proporcionar ningún efecto decorativo luminoso especial. Thus, this type of milky decorative panels makes it possible to provide homogeneous illumination along the entire backlit surface of the interior trim when the light source is active, without providing any special luminous decorative effect.
A la vista de lo anterior, el objeto de la presente invención es guarnecido interior retroiluminado para vehículos capaz de proporcionar un efecto luminoso brillante de intensidad variable cuando la fuente de luz está activa, y capaz de ofrecer un aspecto exterior mejorado cuándo la fuente de luz está apagada, proporcionando en ambos casos, un aspecto más lujoso que el de un guarnecido interior retroiluminado convencional como el descrito en el estado del arte. DESCRIPCION DE LA INVENCION In view of the above, the object of the present invention is backlit interior trim for vehicles capable of providing a bright lighting effect of variable intensity when the light source is active, and capable of offering an improved exterior appearance when the light source it is switched off, in both cases providing a more luxurious appearance than that of a conventional backlit interior trim as described in the state of the art. DESCRIPTION OF THE INVENTION
La presente invención está establecida y caracterizada en las reivindicaciones independientes, mientras que las reivindicaciones dependientes describen características opcionales de la misma. The present invention is established and characterized in the independent claims, while the dependent claims describe optional features thereof.
En primer lugar, la configuración de la invención permite obtener un guarnecido interior retroiluminado cuando la fuente de luz está activa, y al mismo tiempo ocultar dicha fuente de luz cuando ésta se encuentra apagada, como consecuencia de la disposición relativa de los distintos componentes que forman dicho guarnecido interior retroiluminado . In the first place, the configuration of the invention makes it possible to obtain a backlit interior trim when the light source is active, and at the same time hide said light source when it is off, as a consequence of the relative arrangement of the different components that make up said backlit interior trim.
En particular, la interposición del difusor de luz entre el dispositivo de iluminación y la tapa decorativa transparente, permite ocultar dicho dispositivo de iluminación cuando la fuente de luz no se encuentra activa. In particular, the interposition of the light diffuser between the lighting device and the transparent decorative cover, makes it possible to hide said lighting device when the light source is not active.
Gracias a la utilización de una guía de luz formando parte del dispositivo de iluminación, es posible obtener una superficie iluminada extensa con un consumo de energía reducido. Thanks to the use of a light guide as part of the lighting device, it is possible to obtain a large illuminated surface with reduced energy consumption.
Gracias a la particular configuración de la tapa decorativa transparente que comprende en su cara posterior elementos tridimensionales con caras planas inclinadas no paralelas, donde dichos elementos tridimensionales forman en conjunto un patrón, es posible obtener un efecto luminoso brillante que varía dependiendo del ángulo de visión del ocupante del vehículo, asemejándose al que emitiría un diamante. De esta forma se obtiene una iluminación ambiente en el interior del vehículo que ofrece un efecto más atractivo y más lujoso. Este efecto es debido al ángulo de incidencia de la luz sobre las diferentes caras planas inclinadas que forman los elementos tridimensionales, junto al ángulo de visión del ocupante del vehículo con respecto a la tapa decorativa transparente. Es decir, dependiendo del ángulo de visión del ocupante del vehículo respecto al formado por cada una de las caras planas inclinadas que forman la tapa decorativa transparente, éste puede ver áreas con más intensidad de luz y áreas con menos intensidad de luz. Así, a medida que el ocupante del vehículo varía su ángulo de visión respecto a dicha tapa decorativa transparente, éste percibe un efecto luminoso brillante variable producido por el contraste que observa entre las áreas con más intensidad de luz y las áreas con menos intensidad de luz. Thanks to the particular configuration of the transparent decorative cover that comprises on its back face three-dimensional elements with non-parallel inclined flat faces, where said three-dimensional elements together form a pattern, it is possible to obtain a bright luminous effect that varies depending on the viewing angle of the occupant of the vehicle, resembling that which would emit a diamond. From In this way, ambient lighting is obtained inside the vehicle that offers a more attractive and luxurious effect. This effect is due to the angle of incidence of the light on the different inclined flat faces that form the three-dimensional elements, together with the angle of vision of the vehicle occupant with respect to the transparent decorative cover. That is, depending on the viewing angle of the vehicle occupant with respect to that formed by each of the inclined flat faces that form the transparent decorative cover, the latter can see areas with more light intensity and areas with less light intensity. Thus, as the vehicle occupant varies his angle of vision with respect to said transparent decorative cover, he perceives a variable bright luminous effect produced by the contrast he observes between the areas with more light intensity and the areas with less light intensity. .
Por lo tanto, el movimiento del ocupante del vehículo con respecto al tapa decorativa transparente resulta en la obtención de dicho efecto luminoso brillante que se percibe debido a dicho contraste entre áreas con más intensidad de luz y áreas con menos intensidad de luz correspondientes a caras planas inclinadas adyacentes de los elementos tridimensionales, donde dichas porciones de intensidad variable de luz, varían a medida que el ocupante del vehículo se mueve. Therefore, the movement of the vehicle occupant with respect to the transparent decorative cover results in obtaining said bright luminous effect that is perceived due to said contrast between areas with more light intensity and areas with less light intensity corresponding to flat faces. adjacent inclines of the three-dimensional elements, where said portions of variable intensity of light, vary as the occupant of the vehicle moves.
Cuanto más homogénea y más intensa es la luz que recibe la tapa decorativa transparente, mejor es el efecto luminoso brillante obtenido. The more homogeneous and more intense the light received by the transparent decorative cover, the better the light effect bright obtained.
La principal función del difusor de luz es la de mejorar la homogeneidad la luz emitida por el dispositivo de iluminación cuando la fuente de luz está activa. The main function of the light diffuser is to improve the homogeneity of the light emitted by the lighting device when the light source is active.
Asi, la particular disposición del difusor de luz entre la tapa decorativa transparente y el dispositivo de iluminación, permite maximizar el efecto luminoso brillante proporcionado por la tapa decorativa transparente debido a la homogeneidad e intensidad de la luz recibida por ésta a través del difusor de luz. Thus, the particular arrangement of the light diffuser between the transparent decorative cover and the lighting device, allows to maximize the bright luminous effect provided by the transparent decorative cover due to the homogeneity and intensity of the light received by it through the light diffuser. .
Por otro lado, gracias a que la cara frontal de la tapa decorativa transparente está formada por una superficie regular esencialmente plana, la continuidad estética del interior del vehículo no se ve afectada. On the other hand, thanks to the fact that the front face of the transparent decorative cover is formed by an essentially flat regular surface, the aesthetic continuity of the interior of the vehicle is not affected.
Finalmente, como consecuencia de la configuración transparente del panel decorativo en combinación con la configuración de su cara trasera con elementos tridimensionales, y de su cara frontal regular, se obtiene un aspecto visual del recubrimiento decorativo mejorado cuando la fuente de luz está apagada como consecuencia de la incidencia de la luz ambiente presente en el interior del vehículo sobre las caras inclinadas que forman los elementos tridimensionales. Finally, as a consequence of the transparent configuration of the decorative panel in combination with the configuration of its rear face with three-dimensional elements, and of its regular front face, an improved visual appearance of the decorative covering is obtained when the light source is switched off as a result of the incidence of ambient light present inside the vehicle on the inclined faces that form the three-dimensional elements.
