Description

Dispositivo de iluminación de columna.Column lighting device.

La presente invención se refiere a un dispositivo de iluminación de columna.The present invention relates to a column lighting device.

En particular, según la presente invención, se propone un dispositivo de iluminación de columna del tipo de baliza, provisto de ópticas las cuales permiten la distribución uniforme de la luz emitida y aseguran comodidad visual.In particular, according to the present invention, proposes a column lighting device of the type of beacon, provided with optics which allow distribution Uniform of the emitted light and ensure visual comfort.

Los dispositivos de iluminación de columna, también denominados balizas, se pueden dividir en dos grupos de productos: aquellos en los cuales la fuente de luz es visible y aquellos en los cuales la fuente de luz está protegida con respecto al observador.Column lighting devices, also called beacons, they can be divided into two groups of products: those in which the light source is visible and those in which the light source is protected with respect to the observer

Es conocido que los dispositivos de iluminación de columna del primer grupo conllevan el problema de que posiblemente deslumbren al observador, mientras que los dispositivos del segundo un grupo tienen una emisión muy baja de luz debido al hecho de que la pantalla absorbe una parte considerable de la radiación de luz.It is known that lighting devices column of the first group carry the problem that possibly dazzle the observer while the devices of the second one group have a very low emission of light due to the fact that the screen absorbs a part considerable of light radiation.

El documento WO 00/47931 A, que representa el documento de la técnica anterior más próxima, muestra un dispositivo de iluminación de columna según el segundo grupo que comprende un reflector que dirige la luz hacia abajo y hacia el suelo.WO 00/47931 A, which represents the nearest prior art document, show a device  column lighting according to the second group comprising a reflector that directs the light down and towards the ground.

Uno de los problemas relacionados con el bajo rendimiento de los dispositivos de iluminación apantallados se refiere a que ocurre la creación de calor en sus alojamientos.One of the problems related to bass shielded lighting device performance is refers to the creation of heat in their accommodation.

El objetivo principal de la presente invención es, por lo tanto, proporcionar un dispositivo de iluminación de columna, en el cual se evita el sobrecalentamiento del aire en su alojamiento.The main objective of the present invention is, therefore, to provide a lighting device of column, in which the overheating of the air in its accommodation.

Un objetivo adicional de la presente invención es proporcionar un dispositivo de iluminación de columna el cual es fácil y económico de fabricar y manipular.A further objective of the present invention is to provide a column lighting device which is Easy and economical to manufacture and handle.

Estos objetivos según la presente invención se alcanzan proporcionando un dispositivo de iluminación de columna provisto de las características especificadas en la reivindicación 1.These objectives according to the present invention are reach by providing a column lighting device provided with the characteristics specified in the claim one.

Las características adicionales del dispositivo de iluminación de columna de la presente invención se indican en las reivindicaciones subordinadas.Additional device features column lighting of the present invention are indicated in the subordinate claims.

Las características y las ventajas de un dispositivo de iluminación de columna según la presente invención se pondrán de manifiesto a partir de la siguiente descripción ilustrativa y no limitativa, haciendo referencia a los dibujos esquemáticos adjuntos los cuales muestran una vista en sección de una forma de realización preferida del dispositivo de iluminación de columna de la invención.The characteristics and advantages of a column lighting device according to the present invention will become apparent from the following description illustrative and not limiting, referring to the drawings attached schematics which show a sectional view of a preferred embodiment of the lighting device of column of the invention.

Haciendo referencia a la figura, el dispositivo de iluminación de columna 1 consiste en una columna de soporte 2, en cuya parte superior existe un alojamiento 3 para la fuente de luz 4, recubierta por una cubierta 5. La superficie lateral del alojamiento 3, a través de la cual se emite la luz hacia el entorno exterior, consiste en una pantalla 6 para el paso de la luz, fabricada de un material transparente a la luz y resistente a los choques, por ejemplo cristal o, preferentemente un material plástico tal como un policarbonato transparente. Aunque la estructura de la pantalla para el paso de la luz 6 comprende tanto una parte a través de la cual la luz puede ser propagada hacia el exterior del dispositivo de iluminación 1 y también otras partes cuya función es actuar como una pantalla 6 para el resto de la estructura, de aquí en adelante se hará referencia a la pantalla 6 relativa únicamente a la parte a través de la cual la luz puede ser propagada hacia el exterior del dispositivo de iluminación 1, esto es la parte delimitada por el borde superior de las paredes de la columna de soporte 2 y el borde inferior de la cubierta 5.Referring to the figure, the device column lighting 1 consists of a support column 2, in whose upper part there is a housing 3 for the light source 4, covered by a cover 5. The lateral surface of the accommodation 3, through which light is emitted to the environment exterior, consists of a screen 6 for the passage of light, made of a light transparent and resistant material shocks, for example glass or, preferably a plastic material such as a transparent polycarbonate. Although the structure of the screen for the passage of light 6 comprises both a part through from which the light can be propagated to the outside of the lighting device 1 and also other parts whose function is act as a screen 6 for the rest of the structure, from here hereinafter reference will be made to screen 6 relative only to the part through which the light can be propagated to the exterior of the lighting device 1, this is the part bounded by the upper edge of the column walls of support 2 and the bottom edge of the cover 5.

La fuente de luz 4 consiste en una bombilla de emisión 7 rodeada por una ampolla de vidrio 8. La bombilla de emisión 7 está situada a una altura mayor con respecto a la pantalla 6. Inmediatamente por encima de la bombilla de emisión 7, está prevista una pantalla reflectora 9, con una sección curvada, provista de una concavidad orientada hacia abajo. A fin de obtener resultados óptimos con respecto a la distribución y a la uniformidad de la luz, en la proximidad de la base del dispositivo de iluminación de columna 1 y también en el área de los alrededores, las dos ramas de la sección curvada, orientadas hacia el centro, tienen, procediendo desde el centro hacia la periferia de la pantalla reflectora 9, una primera parte ascendente 10, la parte restante de la curva, por el contrario, estando provista de una tendencia descendente. En particular, la parte ascendente 10 presenta una longitud más corta con respecto a la parte restante de la curva. La forma y la colocación de la pantalla reflectora 9 tienen la ventaja de que la distribución hacia fuera de la luz emitida desde la bombilla de emisión 7 y reflejada desde la pantalla reflectora 9 no requiere la presencia de óptica de reflexión adicional y, por lo tanto, es mucho más simple que las soluciones de iluminación conocidas.The light source 4 consists of a bulb emission 7 surrounded by a glass ampoule 8. The bulb emission 7 is located at a higher height with respect to the screen 6. Immediately above the emission bulb 7, it is provided a reflector screen 9, with a curved section, provided with a concavity oriented downwards. In order to get optimal results regarding distribution and uniformity  of light, near the base of the device column 1 lighting and also in the surrounding area, the two branches of the curved section, oriented towards the center, they have, proceeding from the center to the periphery of the reflector screen 9, a first ascending part 10, the part remainder of the curve, on the other hand, being provided with a downward trend. In particular, the rising part 10 it has a shorter length with respect to the remaining part of the curve. The shape and placement of the reflector screen 9 they have the advantage that the distribution out of the light emitted from the emission bulb 7 and reflected from the reflector screen 9 does not require the presence of optical additional reflection and, therefore, is much simpler than known lighting solutions.

La pantalla reflectora 9 está perforada centralmente para permitir que se coloque ligeramente por encima de la bombilla de emisión 7, es decir para alojar la parte superior de la ampolla 8 en el espacio definido entre la pantalla reflectora 9 y la cubierta 5, en el interior de la cual pueden estar convenientemente situados unos elementos capaces de disipar el calor (no representados), los cuales también evitan que el propio calor se concentre en correspondencia con áreas exteriores específicas, la temperatura exterior del dispositivo de iluminación permaneciendo de ese modo por debajo de los límites de seguridad previamente establecidos en todos los puntos.The reflector screen 9 is perforated centrally to allow it to be placed slightly above the emission bulb 7, that is to accommodate the upper part of the vial 8 in the defined space between the reflector screen 9 and cover 5, inside of which they can be conveniently located elements capable of dissipating the heat (not represented), which also prevent the own heat is concentrated in correspondence with outside areas specific, the external temperature of the lighting device thus remaining below safety limits previously established in all points.

Tanto el borde inferior de la cubierta 5 como la parte perimétrica de la pantalla reflectora 9 están más bajos que el extremo inferior de la bombilla de emisión 7 de la fuente de luz 4. Por lo tanto, es imposible que la luz emitida desde la bombilla de emisión 7 pase a través de la pantalla para el paso de la luz 6 siguiendo una trayectoria paralela al suelo o dirigida hacia arriba. De este modo, la bombilla de emisión 7 está completamente escondida de la vista de un observador cuyos ojos estén a una altura por encima de aquella de la pantalla reflectora 6. Además, las partes perimétricas de la pantalla reflectora 9, más curvadas hacia abajo, desvían la luz con ángulos más estrechos y la proyectan en áreas más próximas a la base del dispositivo de iluminación 1.Both the lower edge of the cover 5 and the perimeter part of the reflector screen 9 are lower than the lower end of the emission bulb 7 of the light source 4. Therefore, it is impossible for the light emitted from the bulb of emission 7 pass through the screen for the passage of light 6 following a path parallel to the ground or directed towards above. Thus, the emission bulb 7 is completely hidden from view of an observer whose eyes are at a height above that of the reflector screen 6. In addition, the perimeter parts of the reflector screen 9, more curved towards below, they deflect the light with narrower angles and project it in areas closest to the base of the lighting device 1.

El dispositivo de iluminación de columna 1 también contempla la presencia de una pantalla cilíndrica para la absorción de la luz 11, colocada alrededor de la fuente de luz 4, a una corta distancia de la misma e inmediatamente por debajo del extremo inferior de la bombilla de emisión 7, es decir cuyo extremo superior está a la misma altura que el extremo periférico de la pantalla reflectora 9. Puesto que la altura de la pantalla para la absorción de la luz 11 coincide con el extremo superior de la pantalla para el paso de la luz 6, es decir con el extremo periférico (e inferior) de la pantalla reflectora 9, evita completamente que la luz sea emitida desde el dispositivo de iluminación 1 en una dirección paralela al suelo, eliminando también la posibilidad de que un observador sea deslumbrado por las reflexiones que inevitablemente se producirán. Además de esto, la pantalla para la absorción de la luz 11 también permite que sean eliminadas emisiones directamente hacia arriba de la luz.The column lighting device 1 it also contemplates the presence of a cylindrical screen for light absorption 11, placed around the light source 4, a a short distance from it and immediately below the lower end of the emission bulb 7, that is whose end upper is at the same height as the peripheral end of the reflector screen 9. Since the height of the screen for the light absorption 11 matches the upper end of the screen for the passage of light 6, that is with the end peripheral (and lower) of the reflector screen 9, prevents completely that the light be emitted from the device lighting 1 in a direction parallel to the ground, also eliminating the possibility of an observer being dazzled by the reflections that will inevitably occur. In addition to this, the light absorption screen 11 also allows them to be Eliminated emissions directly up from the light.

En la proximidad de su base, la forma de la pantalla para la absorción de la luz 11 está alargada por un escalón 12 el cual corre a lo largo de la circunferencia completa de la pantalla 11, formando un soporte para una carcasa transparente conformada cilíndricamente 13, preferentemente fabricada de vidrio, opcionalmente coloreada, la cual rodea lateralmente la fuente de luz 4 y físicamente separa el área del alojamiento central 3, el cual aloja la fuente de luz 4, de las áreas más periféricas del mismo alojamiento 3. La presencia de la carcasa 13 evita un sobrecalentamiento excesivo del aire en el alojamiento 3, elevándose el aire caliente hacia arriba y siendo enviado a través del único orificio en correspondencia con el orificio central de la pantalla reflectora 9.In the vicinity of its base, the shape of the light absorption screen 11 is lengthened by a step  12 which runs along the full circumference of the screen 11, forming a support for a transparent housing cylindrically shaped 13, preferably made of glass, optionally colored, which laterally surrounds the source of light 4 and physically separates the central housing area 3, the which houses the light source 4, of the most peripheral areas of the same housing 3. The presence of the housing 13 prevents a excessive air overheating in housing 3, rising the hot air up and being sent through the only hole in correspondence with the central hole of the screen reflector 9.

Además, el dispositivo de iluminación de columna 1, tal como se representa en la figura, comprende una segunda pantalla cilíndrica para la absorción de la luz 14, colocada adicionalmente alejada de la fuente de luz 4 y más baja con respecto a la pantalla 11 situada alrededor de la fuente de luz 4. La función de la segunda pantalla para la absorción de la luz 14, cuya presencia se prefiere pero no es necesaria para los propósitos de la presente invención, es eliminar la formación de signos desagradables que puedan ser proyectados al suelo como resultado de la inevitable variabilidad constructiva de las fuentes de luz utilizadas e incrementar el confort visual.In addition, the column lighting device 1, as depicted in the figure, comprises a second cylindrical screen for light absorption 14, placed additionally away from light source 4 and lower with with respect to the screen 11 located around the light source 4. The function of the second screen for light absorption 14, whose presence is preferred but not necessary for the purposes of the present invention, is to eliminate the formation of signs unpleasant that can be projected to the ground as a result of the inevitable constructive variability of light sources used and increase visual comfort.

La altura de la segunda pantalla para la absorción de la luz 14 de hecho es de tal modo que intercepte todos los rayos de luz emitidos desde la bombilla de emisión 7 los cuales puedan encontrar, en sus trayectorias rectas, primero el borde superior de la primera pantalla para la absorción de la luz 11 y después el borde superior de la pared lateral de la columna de soporte 2 y lo cual podría crear un fenómeno de difracción indeseable responsable de la formación de las denominadas "manchas claro oscuras".The height of the second screen for the light absorption 14 is in fact such that it intercepts all the light rays emitted from the emission bulb 7 which can find, in their straight paths, first the edge top of the first screen for light absorption 11 and then the upper edge of the side wall of the column of support 2 and which could create a diffraction phenomenon undesirable responsible for the formation of the so-called "dark spots."

Finalmente, la base 15 del alojamiento 3 está también convenientemente fabricada de modo que sea capaz de ser considerada un absorbente de la luz, para permitir la eliminación del fenómeno relacionado con la producción de reflexiones parásitas (o reflexiones de luz) para ser incluso más eficaz.Finally, base 15 of housing 3 is also conveniently manufactured so that it is capable of being considered a light absorber, to allow removal of the phenomenon related to the production of parasitic reflections (or light reflections) to be even more effective.

El dispositivo de iluminación de columna según la presente invención permite una distribución de la luz óptima y uniforme, con respecto en particular a las áreas más próximas a su base.The column lighting device according to The present invention allows for optimal light distribution and uniform, with regard in particular to the areas closest to its base.

Además, el dispositivo de iluminación según la presente invención evita la formación del fenómeno de deslumbramiento para un observador y un calor excesivo del alojamiento 3 y de las paredes exteriores de la pantalla para el paso de la luz 6 y la cubierta 5.In addition, the lighting device according to the The present invention prevents the formation of the phenomenon of glare for an observer and excessive heat of housing 3 and the outer walls of the screen for the passage of light 6 and cover 5.

Finalmente, el dispositivo de iluminación de columna según la presente invención proporciona una solución la cual es simple y económica de fabricar y manipular, particularmente en virtud del hecho de que, en lugar de una combinación complicada de ópticas, contempla la presencia de un único elemento reflector el cual distribuye la luz tanto cerca de la base del dispositivo de iluminación de columna 1 como en el área de los alrededores.Finally, the lighting device of column according to the present invention provides a solution the which is simple and economical to manufacture and handle, particularly under the fact that, instead of a complicated combination of optics, contemplates the presence of a single reflector element the which distributes the light both near the base of the device column lighting 1 as in the surrounding area.
