Description

Dispositivo antideslumbramiento para fuentes de luz de tipo LED. Anti-glare device for LED light sources.

La presente invención se refiere a sistemas de iluminación con una fuente de luz roja y, en particular, a dispositivos antideslumbramiento para fuentes de luz de tipo LED aptas para limitar la posibilidad de que la luz de dichas fuentes ilumine excesivamente áreas del campo visual de un observador, provocándole incomodidad o una reducción en su percepción visual. The present invention relates to lighting systems with a red light source and, in particular, anti-glare devices for LED light sources suitable for limiting the possibility that the light of said sources excessively illuminates areas of the visual field of a observer, causing discomfort or a reduction in his visual perception.

En el campo de los dispositivos de iluminación se sabe que el uso de fuentes de luz de tipo LED (diodos de emisión de luz), en particular de las fuentes de tipo LED desarrolladas más recientemente, denominadas LED de potencia, está llegando a ser cada vez más amplio. In the field of lighting devices it is known that the use of LED-type light sources (light emitting diodes), in particular of the most recently developed LED-type sources, called power LEDs, is becoming every wider

Debido a la cantidad incrementada de luz que estas fuentes son capaces de emitir, combinado con el hecho de que la fuente desde la cual ésta se deriva tiene una superficie extremadamente reducida (miniaturizada a tal grado que se la considera prácticamente puntiforme), la luminancia de fuentes de tipo LED ha alcanzado ahora niveles extremadamente altos. Además de esto, pero teniendo en mente los estándares de luminancia que son solicitados actualmente de los aparatos de iluminación profesionales, deberá considerarse que las fuentes de tipo LED de potencia han excedido los niveles de comodidad visual normalmente aceptados. En resumen, aunque la última generación de dispositivos de iluminación de tipo LED ha alcanzado un alto rendimiento fotométrico, muy Due to the increased amount of light that these sources are capable of emitting, combined with the fact that the source from which it is derived has an extremely small surface area (miniaturized to such a degree that it is considered practically punctate), the luminance of LED type sources have now reached extremely high levels. In addition to this, but keeping in mind the luminance standards that are currently requested from professional lighting fixtures, LED power sources should be considered to have exceeded the levels of visual comfort normally accepted. In summary, although the latest generation of LED-type lighting devices has achieved high photometric performance, very

frecuentemente generan una “incomodidad visual”. frequently generate a "visual discomfort."

Están actualmente disponibles dispositivos de iluminación que han afrontado este problema aplicando un acabado vidriado y/o repujado en el cristal frontal de los dispositivos que, desviando y atenuando el haz de luz emitido, contribuye a reducir el deslumbramiento generado por las fuentes de luz individuales. Por el contrario, estas soluciones reducen considerablemente la intensidad máxima emitida a lo largo del eje óptico. Esto significa que se ha alcanzado la máxima comodidad visual en detrimento de las prestaciones fotométricas del dispositivo de iluminación. Lighting devices are currently available that have addressed this problem by applying a glazed and / or embossed finish on the front glass of the devices that, by deflecting and attenuating the beam of light emitted, contributes to reducing the glare generated by individual light sources. On the contrary, these solutions considerably reduce the maximum intensity emitted along the optical axis. This means that maximum visual comfort has been achieved to the detriment of the photometric performance of the lighting device.

El documento EP 0 683 355 describe una lámpara de coche que tiene un prisma que desvía hacia atrás los haces de luz incidente emitidos por una fuente de luz y reflejados por un reflector principal hacia reflectores adicionales. Los reflectores adicionales retransmiten los haces de luz hacia delante a través de una lente para conseguir una iluminación uniforme de la lente. Los lados del prisma que producen la desviación son superficies reflectantes plateadas. EP 0 683 355 describes a car lamp that has a prism that deflects the incident light beams emitted by a light source and reflected by a main reflector towards additional reflectors. Additional reflectors relay the light beams forward through a lens to achieve uniform illumination of the lens. The sides of the prism that produce the deflection are silver reflective surfaces.

Por tanto, un objetivo principal de la presente invención es proporcionar un dispositivo antideslumbramiento para fuentes de luz de tipo LED que no limite sus prestaciones fotométricas. Therefore, a main objective of the present invention is to provide an anti-glare device for LED light sources that does not limit its photometric performance.

Otro objetivo de la presente invención es proporcionar un dispositivo antideslumbramiento para fuentes de luz de tipo LED, en el que se alcance el objetivo de una manera simple y económica, sin requerir modificaciones sustanciales de la estructura del sistema de iluminación, con respecto a las soluciones ya presentes en el mercado. Another objective of the present invention is to provide an anti-glare device for LED-type light sources, in which the objective is achieved in a simple and economical manner, without requiring substantial modifications of the lighting system structure, with respect to the solutions. already present in the market.

Estos objetivos según la presente invención se alcanzan proporcionando un dispositivo antideslumbramiento para fuentes de luz de tipo LED que tiene las características especificadas en la reivindicación 1. These objectives according to the present invention are achieved by providing an anti-glare device for LED-type light sources having the characteristics specified in claim 1.

Otras características del dispositivo antideslumbramiento de la presente invención se indican en las reivindicaciones dependientes posteriores. Other features of the anti-glare device of the present invention are indicated in the subsequent dependent claims.

Las características y ventajas de un dispositivo antideslumbramiento según la presente invención se pondrán más claramente de manifiesto a partir de la siguiente descripción ilustrativa y no limitativa, haciendo referencia a los dibujos esquemáticos adjuntos, en los cuales: The features and advantages of an anti-glare device according to the present invention will be more clearly apparent from the following illustrative and non-limiting description, referring to the accompanying schematic drawings, in which:

La figura 1 muestra una vista en perspectiva de los componentes de un sistema de iluminación de tipo LED al que se aplica un dispositivo antideslumbramiento según una primera forma de realización de la presente invención, Figure 1 shows a perspective view of the components of an LED type lighting system to which an anti-glare device is applied according to a first embodiment of the present invention,

La figura 2 muestra una vista en sección del sistema de iluminación de la figura 1, y Figure 2 shows a sectional view of the lighting system of Figure 1, and

La figura 3 muestra una vista en perspectiva de los componentes de un sistema de iluminación de tipo LED al que se aplica un dispositivo antideslumbramiento según una segunda forma de realización de la presente invención. Figure 3 shows a perspective view of the components of an LED type lighting system to which an anti-glare device is applied according to a second embodiment of the present invention.

Con referencia a las figuras 1 y 2, un dispositivo antideslumbramiento 1 según la presente invención se aplica a una fuente de tipo LED 2 sobre la cual hay una lente 3 cuya función es hacer que converja el haz de luz generado por el LED 2 en una dirección definida. With reference to Figures 1 and 2, an anti-glare device 1 according to the present invention is applied to a source of type LED 2 on which there is a lens 3 whose function is to make the beam of light generated by LED 2 converge into a defined address

El dispositivo antideslumbramiento 1 comprende un cuerpo de protección principal 4 realizado en un material opaco, preferiblemente negro. En el caso específico mostrado en la figura, el cuerpo de protección 4 ayuda a asegurar el acoplamiento entre la fuente de tipo LED 2 y la lente 3, ya que está equipado en su parte inferior con un asiento cónico 5 para el alojamiento de la fuente de tipo LED 2 y, con su pared lateral 6, define un asiento para la lente 3. The anti-glare device 1 comprises a main protection body 4 made of an opaque material, preferably black. In the specific case shown in the figure, the protective body 4 helps ensure the coupling between the LED type 2 source and the lens 3, since it is equipped at the bottom with a conical seat 5 for the source housing LED type 2 and, with its side wall 6, defines a seat for lens 3.

Sin embargo, la función principal de la pared lateral 6 es proteger la luz emitida desde la fuente de luz de tipo LED y dirigida a lo largo de direcciones cuyo ángulo con respecto al eje A-A es perpendicular o en cualquier caso mayor que un cierto valor. Cuanto más alta sea la pared lateral 6, mayor será la protección lateral de la luz emitida. Esta función es particularmente importante en casos en los que la lente 3 no se aplica a la fuente de tipo LED 2 para hacer que converja la luz en una dirección definida. However, the main function of the side wall 6 is to protect the light emitted from the LED-type light source and directed along directions whose angle with respect to the A-A axis is perpendicular or in any case greater than a certain value. The higher the side wall 6, the greater the lateral protection of the emitted light. This function is particularly important in cases where the lens 3 is not applied to the LED type 2 source to make the light converge in a defined direction.

La figura muestra también que un segundo cuerpo de protección 7, realizado en un material opaco, preferiblemente negro, está ensamblado sobre la lente 3. El cuerpo de protección 7 mostrado tiene una pared lateral 8 que forma una extensión y, en consecuencia, una protección lateral adicional con respecto al de la pared lateral 6 del cuerpo de protección principal 4, y que impide que la luz que procede de las partes periféricas de la lente 3 incida directamente en los ojos de un observador que esté al lado del sistema de iluminación. El cuerpo de protección 7 mostrado en la figura está equipado además con paredes medianas y, en particular, con un elemento tubular 9 dispuesto en una posición central, cuyo diámetro tiene dimensiones reducidas con respecto al perímetro del cuerpo de protección 7. The figure also shows that a second protection body 7, made of an opaque material, preferably black, is assembled on the lens 3. The protection body 7 shown has a side wall 8 that forms an extension and, consequently, a protection additional side with respect to that of the side wall 6 of the main protection body 4, and which prevents the light coming from the peripheral parts of the lens 3 from directly entering the eyes of an observer that is next to the lighting system. The protection body 7 shown in the figure is further equipped with medium walls and, in particular, with a tubular element 9 arranged in a central position, the diameter of which has reduced dimensions with respect to the perimeter of the protection body 7.

En particular, las dimensiones del elementos tubular 9 son tales que se adapten a una muesca 10 de la lente 3 correspondiente a la parte superior de la fuente de tipo LED 2. La función del elemento cilíndrico 9 es, en particular, proteger adecuadamente la parte de la lente 3 en la que se tiene la mayor concentración del flujo luminoso emitido desde la fuente de luz de tipo LED 2. In particular, the dimensions of the tubular elements 9 are such that they fit a notch 10 of the lens 3 corresponding to the upper part of the LED type 2 source. The function of the cylindrical element 9 is, in particular, to adequately protect the part of the lens 3 in which there is the highest concentration of the luminous flux emitted from the LED light source 2.

El elemento tubular 9 está hecho de una sola pieza con la pared lateral 8 del cuerpo de protección 7 por medio de dos brazos 11. The tubular element 9 is made in one piece with the side wall 8 of the protection body 7 by means of two arms 11.

Más generalmente, las paredes medianas pueden consistir en uno o más anillos concéntricos, circulares o poligonales, y puede tener también una forma de nido de abeja y su distancia, en una vista en planta o en alzado, desde la fuente de luz de tipo LED 2, así como su altura, dependen del ángulo de protección a obtener. More generally, the medium walls may consist of one or more concentric, circular or polygonal rings, and may also have a honeycomb shape and its distance, in a plan or elevation view, from the LED light source 2, as well as its height, depend on the angle of protection to be obtained.

El cuerpo de protección 7 se completa con dos lengüetas 12 en cuyos extremos hay un diente 13, para el acoplamiento de pinzado con un asiento cónico 14 del cuerpo de protección principal 4. The protection body 7 is completed with two tabs 12 at the ends of which there is a tooth 13, for the pinching coupling with a conical seat 14 of the main protection body 4.

Con referencia a la figura 3, ésta muestra una forma de realización diferente del sistema de iluminación de tipo LED con un dispositivo antideslumbramiento según la presente invención. With reference to Figure 3, this shows a different embodiment of the LED lighting system with an anti-glare device according to the present invention.

En particular, se muestra un sistema de iluminación equipado con tres fuentes de luz de tipo LED 2, cada una de las cuales tiene una lente 3. En este caso, es particularmente conveniente tener una máscara 15, en lugar de tres cuerpos de protección 7 independientes y completamente similares a los mostrados con referencia a las figuras 1 y In particular, a lighting system equipped with three LED light sources 2 is shown, each of which has a lens 3. In this case, it is particularly convenient to have a mask 15, instead of three protective bodies 7 independent and completely similar to those shown with reference to figures 1 and

2. La forma de realización particular mostrada en la figura 3 puede hacer conveniente recurrir a sistemas de apantallamiento y de acoplamiento entre los componentes del sistema de iluminación que sean diferentes de los mostrados en las figuras 1 y 2. En particular, puede contemplarse un único cuerpo de protección principal o bien diversos cuerpos de protección del mismo tipo que los mostrados en las figuras 1 y 2, en cualquier caso capaces también de acoplar los componentes restantes del sistema de iluminación a la máscara 15. 2. The particular embodiment shown in Figure 3 may make it convenient to use screening and coupling systems between the components of the lighting system that are different from those shown in Figures 1 and 2. In particular, a single main protection body or various protection bodies of the same type as those shown in figures 1 and 2, in any case also capable of attaching the remaining components of the lighting system to the mask 15.

Es evidente que el dispositivo antideslumbramiento para fuentes de luz de tipo LED de la presente invención es capaz de limitar efectivamente la posibilidad de deslumbrar a un observador, sin tener ninguna limitación innecesaria de sus prestaciones fotométricas. It is clear that the anti-glare device for LED light sources of the present invention is capable of effectively limiting the possibility of dazzling an observer, without having any unnecessary limitation of its photometric performance.

Además, el dispositivo antideslumbramiento de la presente invención forma una solución para una producción y manipulación simples y económicas. In addition, the anti-glare device of the present invention forms a solution for simple and economical production and handling.

La presente invención se describe para fines ilustrativos y no limitativos según sus formas de realización preferidas, pero se entiende que pueden aplicarse variaciones y/o modificaciones por expertos en este campo, todas ellas incluidas en el alcance de protección, como se define en las reivindicaciones adjuntas. The present invention is described for illustrative and non-limiting purposes according to their preferred embodiments, but it is understood that variations and / or modifications may be applied by experts in this field, all of which are included in the scope of protection, as defined in the claims. attached.

En particular, las formas y también los materiales del sistema de iluminación y del dispositivo antideslumbramiento de la invención pueden diferir de los mostrados para fines puramente ilustrativos en los dibujos. In particular, the shapes and materials of the lighting system and the anti-glare device of the invention may differ from those shown for purely illustrative purposes in the drawings.
