Description

LENTE OPTICA PARA FAROS DE VEHICULOS  OPTICAL LENS FOR VEHICLE HEADLIGHTS
D E S C R I P C I Ó N D E S C R I P C I Ó N
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a una lente óptica para faros de vehículos, del tipo de las encargadas de proyectar la luz que emiten las bombillas principales de los faros, siendo aplicable a cualquier tipo de vehículo, ya sea un automóvil, un camión, una motocicleta, un tractor, un autocar, etc. The present invention relates to an optical lens for vehicle headlights, of the type in charge of projecting the light emitted by the headlight bulbs, being applicable to any type of vehicle, be it a car, a truck, a motorcycle , a tractor, a coach, etc.
El objeto de la invención es proporcionar una lente de muy bajo coste de fabricación y mantenimiento, con elevadas capacidades de diseño, mas rápido de fabricar, resistente y ligero lo que repercute en un ahorro de energía consumida por el vehículo, al tener que mover menos peso. The object of the invention is to provide a lens of very low manufacturing and maintenance cost, with high design capabilities, faster to manufacture, resistant and lightweight which results in a saving of energy consumed by the vehicle, having to move less weight.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Las lentes ópticas que participan en los faros utilizados en vehículos para proyectar la luz sobre la calzada están obtenidas hasta la fecha en vidrio o materiales minerales, en orden a soportar las altas temperaturas que alcanzan las lámparas, ya sean halógenas o de xenón, sin que estas sufran deformaciones. The optical lenses that participate in the headlights used in vehicles to project the light on the roadway are obtained to date in glass or mineral materials, in order to withstand the high temperatures reached by the lamps, either halogen or xenon, without These undergo deformations.
El problema que presenta este tipo de material es que resulta frágil, es pesado, caro y difícil de construir, con limitaciones en su diseño de fabricación, y con un proceso de fabricación prolongado en el tiempo. DESCRIPCIÓN DE LA INVENCIÓN The problem with this type of material is that it is fragile, it is heavy, expensive and difficult to build, with limitations in its manufacturing design, and with a long manufacturing process. DESCRIPTION OF THE INVENTION
La lente óptica para faros de vehículos que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta en base a una solución sencilla pero de gran eficacia, constituyendo un elemento de muy bajo coste de fabricación y mantenimiento, con posibilidades de fabricación superiores a las del vidrio, mas rápido de fabricar, resistente y ligera. The optical lens for headlights of vehicles that the invention proposes solves in a fully satisfactory manner the above-mentioned problem based on a simple but highly effective solution, constituting an element of very low manufacturing and maintenance cost, with manufacturing possibilities exceeding of glass, faster to manufacture, resistant and lightweight.
Para ello, y de forma mas concreta, la lente que se preconiza parte de la estructuración básica convencional de este tipo de lentes, si bien podría adoptar formas mas complejas de acuerdo con diferentes líneas de diseño, con la particularidad de que la misma esta obtenida en un material orgánico, tal como plástico. To do this, and more specifically, the lens that is recommended part of the conventional basic structuring of this type of lens, although it could take more complex forms according to different design lines, with the particularity that it is obtained in an organic material, such as plastic.
De forma mas concreta, la lente se puede materializar en policarbonato o PMMA, material sumamente ligero, barato y fácil de moldear. More specifically, the lens can be materialized in polycarbonate or PMMA, extremely light material, cheap and easy to mold.
Dada la naturaleza de la lente, resulta obvio que la misma no está prevista para ser implantada en faros con lámparas convencionales, ya sean halógenas o de xenón, ya que las mismas se verían afectadas por el calor que emiten este tipo de fuentes de iluminación, sufriendo deformaciones, si bien resulta de especial aplicación a los faros de nueva construcción con nuevas tecnologías, como por ejemplo de iluminación led, o cualquier otra tecnología que pueda surgir en la que las fuentes de luz apenas transmitan calor, consiguiéndose el gran número de ventajas anteriormente comentadas. Given the nature of the lens, it is obvious that it is not intended to be implanted in headlights with conventional lamps, either halogen or xenon, since they would be affected by the heat emitted by this type of lighting source, undergoing deformations, although it is of special application to new-built headlights with new technologies, such as led lighting, or any other technology that may arise in which light sources barely transmit heat, achieving the large number of advantages previously commented.
DESCRIPCIÓN DE LOS DIBUJOS DESCRIPTION OF THE DRAWINGS
Para complementar la descripción que seguidamente se va a realizar y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente: La figura 1.- Muestra una vista en sección de un faro de un vehículo en el que esta implantada una lente realizada de acuerdo con el objeto de la presente invención. To complement the description that will then be made and in order to help a better understanding of the features of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented: Figure 1 shows a sectional view of a headlight of a vehicle in which a lens made in accordance with the object of the present invention is implanted.
La figura 2.- Muestra una vista ampliada de la lente que participa en el conjunto de la figura anterior. Figure 2.- Shows an enlarged view of the lens that participates in the assembly of the previous figure.
REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
Como se puede observar en las figuras reseñadas, y mas concretamente en la figura 1 , se muestra un faro (1) de un vehículo, con su correspondiente parábola (2), en cuyo seno se establece una fuente de iluminación (3) a base de led's, pero que, tal y como se ha comentado anteriormente puede materializarse en cualquier fuente de iluminación que emita poco calor durante su funcionamiento, a la cual se asocia una carcasa (4) reflectante, soporte de una lente (5) que proyecta la luz aumentando su potencia luminosa. As can be seen in the figures outlined, and more specifically in Figure 1, a headlight (1) of a vehicle is shown, with its corresponding parabola (2), in which a light source (3) is established based of LEDs, but which, as previously mentioned, can be materialized in any lighting source that emits little heat during operation, to which a reflective housing (4) is associated, a lens holder (5) that projects the light increasing its light power.
Pues bien, de acuerdo ya con la invención, se ha previsto que la lente (5) esté obtenida en un material orgánico, tal como plástico, o de forma mas concreta policarbonato o PMMA. Este material es sumamente ligero, barato y fácil de moldear, de manera que la geometría que presenta la lente (5) en la figura 2, es simplemente ejemplaria, pudiéndose moldear de acuerdo con formas mas complejas de lo que permite el vidrio, y adaptarse a diferentes necesidades específicas, todo ello con un proceso de fabricación mucho mas rápido. Well, according to the invention, it is provided that the lens (5) is obtained in an organic material, such as plastic, or more specifically polycarbonate or PMMA. This material is extremely light, cheap and easy to mold, so that the geometry presented by the lens (5) in Figure 2, is simply exemplary, being able to mold according to more complex shapes than the glass allows, and adapt to different specific needs, all with a much faster manufacturing process.
