DISPOSITIVO DE ILUMINACION  LIGHTING DEVICE

OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a un dispositivo de iluminación, del tipo de los que incorporan una fuente de iluminación, ya sea una bombilla, un fluorescente, un proyector, diodos led, etc, ya sea de uso domestico o industrial, y que incorporan una lente para la transmisión de la luz emitida por la fuente de iluminación. The present invention relates to a lighting device, of the type that incorporates a light source, either a bulb, a fluorescent, a projector, LEDs, etc., whether for domestic or industrial use, and incorporating a lens for the transmission of the light emitted by the lighting source.
El objeto de la invención es conseguir una mínima pérdida en la transmisión de la luz emitida por el dispositivo de iluminación. The object of the invention is to achieve a minimum loss in the transmission of the light emitted by the lighting device.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Como es sabido, todas las superficies ópticas, producen reflexión, viéndose reflejada parte de la luz proyectada por el emisor luminoso, perdiendo eficiencia lumínica y produciendo brillos parásitos, así como pérdida de contraste, etc. As it is known, all optical surfaces produce reflection, being reflected part of the light projected by the light emitter, losing light efficiency and producing parasitic brightness, as well as loss of contrast, etc.
Si se utiliza como emisor de luz las lámparas tipo led, la pérdida de luminosidad, es decir de flujo luminoso cuando se traspasa un medio transparente de tipo plástico, oscila entre el 8% y el 16%, porcentaje de pérdida que depende del tipo de material plástico utilizado y de su espesor, de manera que en cualquier caso esa pérdida de flujo luminoso lleva consigo una sustancial reducción de la luz emitida por el emisor inicial. If the LED-type lamps are used as a light emitter, the loss of luminosity, that is to say of luminous flux when a transparent medium of plastic type is transferred, ranges between 8% and 16%, percentage of loss that depends on the type of plastic material used and its thickness, so that in any case this loss of luminous flux leads to a substantial reduction in the light emitted by the initial emitter.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
El dispositivo de iluminación que se preconiza ha sido concebida para resolver la problemática anteriormente expuesta, de manera que, partiendo de la estructuración convencional de cualquier tipo de dispositivo de iluminación como los anteriormente comentados, que incorporan una lente para la transmisión de la luz emitida por la fuente de iluminación de que se trate, ya sea una bombilla, un fluorescente, un proyector, diodos led, etc.presenta la particularidad de que la superficie de dicha lente está dotada de un revestimiento antirreflejante, consiguiéndose con ello mejorar la intensidad y precisión de la luz transmitida por la fuente emisora de luz, de manera tal que el tratamiento antirreflejante aplicado sobre la superficie de la lente verá reducida la luz reflejada y no deseada que se emite en las superficies plásticas utilizadas en los emisores de luz. The lighting device that is recommended has been conceived to solve the above-mentioned problem, so that, based on the conventional structuring of any type of lighting device such as those previously mentioned, that incorporate a lens for the transmission of the light emitted by source The lighting in question, be it a light bulb, a fluorescent lamp, a projector, LEDs, etc., has the peculiarity that the surface of said lens is provided with a non-reflective coating, thereby improving the intensity and accuracy of the light transmitted by the light emitting source, so that the anti-reflective treatment applied to the lens surface will reduce the reflected and unwanted light emitted on the plastic surfaces used in the light emitters.
La superficie antirreflejante puede aplicarse tanto a lentes cóncavas como a lentes convexas o neutras, así como a superficies plásticas, superficies trasparentes o carcasas protectoras por las que pasa luz, con la particularidad de que en cualquier caso la pérdida de transmisión de luz oscilará entre 1 % y 3%, comparado con el porcentaje del 8% al 16% tradicional, con lo que la luz emitida por el emisor de luz será mucho mayor, pudiéndose estimar que una lente que lleve la superficie antirreflejante emitirá entre un 7% y un 13% mas de luz que las lentes convencionales, dependiendo lógicamente de los materiales y espesores utilizados. The anti-reflective surface can be applied both to concave lenses and to convex or neutral lenses, as well as to plastic surfaces, transparent surfaces or protective housings through which light passes, with the particularity that in any case the loss of light transmission will range between 1 % and 3%, compared to the traditional 8% to 16% percentage, so that the light emitted by the light emitter will be much higher, and it can be estimated that a lens that carries the anti-reflective surface will emit between 7% and 13 % more light than conventional lenses, logically depending on the materials and thicknesses used.
Evidentemente el dispositivo de iluminación puede incluir una o mas lentes, en cuyo segundo caso todas las lentes irán dotadas del tratamiento antirreflejante en su superficie, y cuya superficie antirreflejante está constituida por múltiples capas muy finas que se depositan en alto vacío mediante la evaporación de ciertas sustancias, produciéndose una serie de interferencias por las que la luz reflejada se anula, aumentando la luz transmitida, con lo que se consigue un aumento de la transmitancia de la luz y una reducción a porcentajes mínimos de la luz reflejada. También cabe decir que la lente o lentes utilizadas podrán ser de material orgánico o inorgánico (mineral), y el revestimiento antirreflejante que se aplica a la superficie de la lente podrá ser por una cara o por ambas. Obviously the lighting device can include one or more lenses, in which second case all the lenses will be provided with the anti-reflective treatment on their surface, and whose anti-reflective surface is constituted by multiple very thin layers that are deposited in high vacuum by evaporation of certain substances, producing a series of interferences by which the reflected light is canceled, increasing the transmitted light, thereby achieving an increase in the transmittance of the light and a reduction to minimum percentages of the reflected light. It should also be said that the lens or lenses used may be of organic or inorganic (mineral) material, and the anti-reflective coating that is applied to the surface of the lens may be on one side or both.
En definitiva, se consigue mediante el dispositivo de la invención una fuente de iluminación con una mayor eficiencia lumínica, con el mismo consumo energético, o bien emitir la misma luz con un menor gasto energético, y en cualquier caso con menores costes de fabricación. DESCRIPCIÓN DE LOS DIBUJOS In short, a lighting source with a higher light efficiency, with the same energy consumption, or emit the same light with a lower energy expenditure, and in any case with lower manufacturing costs, is achieved by the device of the invention.
