El objetivo de la presente invención consiste en realizar un dispositivo de iluminación que presente gran eficacia y una estructura de pequeño tamaño, sencilla, rentable.The objective of the present invention is to make a lighting device that has great efficiency and A small structure, simple, cost effective.

Con el fin de alcanzar dicho objetivo, la invención se refiere a un dispositivo de iluminación que presenta todas las características indicadas en la reivindica-
ción 1.In order to achieve said objective, the invention relates to a lighting device that has all the characteristics indicated in the claim.
tion 1.

El dispositivo según la presente invención puede estar equipado con una lente dispuesta frente al reflector primario y al reflector secundario con una superficie interior que puede estar equipada de manera parcial o total con microprismas.The device according to the present invention can be equipped with a lens arranged in front of the primary reflector and to the secondary reflector with an inner surface that can be partially or totally equipped with microprisms.

La presente invención se pondrá más claramente de manifiesto a partir de las siguientes descripciones, haciendo referencia a las figuras adjuntas, proporcionadas a título de ejemplo no limitativo, en las que:The present invention will become more clearly manifest from the following descriptions, making reference to the attached figures, provided by way of non-limiting example, in which:

- la figura 1 es una posible vista esquemática de un ejemplo de forma de realización del dispositivo de iluminación según la presente invención,- Figure 1 is a possible schematic view of an exemplary embodiment of the lighting device according to the present invention,

- la figura 2 es una vista en sección transversal por la línea II-II de la figura 1,- Figure 2 is a cross-sectional view along line II-II of figure 1,

- la figura 3 es una variación de la figura 2 y- figure 3 is a variation of figure 2 Y

- las figuras 4 a 6 ilustran dos variaciones adicionales de la figura 2.- Figures 4 to 6 illustrate two variations Additional figure 2.

Haciendo referencia a las figuras 1, 2, el número de referencia 1 indica en general un dispositivo de iluminación que comprende un par de fuentes de luz 2 en forma de tubos fluorescentes, con una dirección longitudinal extendida. Asociada a las dos fuentes de luz se encuentra una estructura reflectora, indicada en general con el número de referencia 3. Como se aprecia claramente en la figura 2, la estructura reflectora presenta un reflector primario 4 y un reflector secundario 5 asociados a cada fuente de luz 2. Cada reflector primario 4 presenta, en un plano que es perpendicular a la dirección longitudinal de las fuentes de luz 2 (ver la figura 2) un perfil que consiste en dos secciones de voluta 6, 7 que presentan unas superficies cóncavas enfrentadas a la fuente 2 y unidas entre sí para formar una cúspide 8, dispuesta inmediatamente adyacente a la fuente 2. El eje 4a de la doble cúspide está inclinado hacia el reflector secundario 5. Cada reflector secundario 5 presenta una pluralidad de sectores reflectores activos 9 que corresponden, por ejemplo, a unas partes de una parábola o presentan una geometría compleja de cualquier tipo, unidos mediante secciones de unión 10, dispuestas radialmente con respecto al extremo libre 7a orientado hacia fuera con respecto al perfil de voluta doble del reflector primario 4.Referring to figures 1, 2, the number reference 1 generally indicates a lighting device that comprises a pair of light sources 2 in the form of tubes fluorescent, with an extended longitudinal direction. Associated to the two light sources is a reflective structure, indicated in general with reference number 3. As can be seen clearly in figure 2, the reflective structure has a primary reflector 4 and a secondary reflector 5 associated with each light source 2. Each primary reflector 4 presents, in a plane that is perpendicular to the longitudinal direction of the light sources 2 (see figure 2) a profile consisting of two volute sections 6, 7 presenting concave surfaces facing the source 2 and joined together to form a cusp 8, arranged immediately adjacent to source 2. Axis 4a of the double cusp is inclined towards the secondary reflector 5. Each secondary reflector 5 has a plurality of sectors active reflectors 9 corresponding, for example, to parts of a parabola or present a complex geometry of any type, joined by joining sections 10, arranged radially with respect to the free end 7a oriented outwards with respect to the double volute profile of the primary reflector 4.

En su funcionamiento, los reflectores secundarios 5 reflejan los rayos de luz directamente de la fuente de luz 2 asociada a los mismos o reflejada por el reflector primario 4 hacia fuera (es decir, hacia la derecha con referencia a la figura 2).In its operation, secondary reflectors 5 reflect the light rays directly from the light source 2 associated with them or reflected by the primary reflector 4 towards outside (that is, to the right with reference to figure 2).

Gracias a la geometría particular descrita anteriormente, el dispositivo de iluminación presenta gran eficacia (del orden del 80%) de extracción de la luz en la dirección de salida del caudal de luz con respecto a la energía de producción total. Al mismo tiempo, la dimensión del dispositivo en la dirección de salida del haz luminoso es sumamente reducida, lo cual hace al dispositivo adecuado también, por ejemplo, para iluminar habitaciones en hogares o locales de trabajo, montado en el techo o en la pared con los dos reflectores secundarios 5 ambos adyacentes al techo, debido a que, en esta posición, el dispositivo sólo sobresaldrá ligeramente de la superficie en la cual se fija.Thanks to the particular geometry described previously, the lighting device has great efficiency (of the order of 80%) of extraction of light in the direction of output of the light flow with respect to the production energy total. At the same time, the dimension of the device in the direction The output of the light beam is greatly reduced, which makes suitable device also, for example, to illuminate rooms in homes or workplaces, ceiling mounted or on the wall with the two secondary reflectors 5 both adjacent to the ceiling, because, in this position, the device only it will protrude slightly from the surface on which it is fixed.

La figura 3 ilustra una variación con una fuente única 2, que presenta un perfil que corresponde esencialmente a una mitad del perfil de la figura 2.Figure 3 illustrates a variation with a source only 2, which presents a profile that essentially corresponds to a half of the profile in figure 2.

La figura 4 ilustra una variación que se diferencia de la solución de la figura 2 únicamente por el hecho de que está prevista con una lente 11 que cierra la parte frontal del dispositivo y que presenta una superficie interior provista de manera parcial o total de microprismas 12.Figure 4 illustrates a variation that difference from the solution of figure 2 solely because of the fact which is provided with a lens 11 that closes the front of the device and which has an inner surface provided with partial or total manner of microprisms 12.

La figura 5 ilustra una variación de la figura 3, que no forma parte de la presente invención, en la cual se han realizado unas ranuras 13 entre las partes activas 9 del reflector secundario y en la cual cada parte activa 9 está equipada con una lengüeta adicional 14 para reflejar los rayos de luz que inciden en su superficie posterior (con referencia a la dirección de salida principal del haz luminoso) en la dirección opuesta a dicha dirección principal. La solución de la figura 5 puede utilizarse, por ejemplo, para iluminar el interior de paneles luminosos verticales visibles por ambos lados, tal como es el caso, por ejemplo, en los paneles luminosos que indican salidas de incendios en lugares públicos o locales de trabajo.Figure 5 illustrates a variation of Figure 3, which is not part of the present invention, in which they have been made slots 13 between the active parts 9 of the reflector secondary and in which each active part 9 is equipped with a additional tab 14 to reflect the light rays that affect its rear surface (with reference to the direction of departure main beam) in the opposite direction Main address. The solution of Figure 5 can be used, for example, to illuminate the interior of luminous panels verticals visible on both sides, as is the case, by example, in the light panels indicating fire exits in public places or workplaces.

En la variante de la figura 6, la parte central del dispositivo está más extendida hacia fuera, sobre el borde de la pared o techo. Esta solución es particularmente adecuada para aplicaciones de techo en las cuales la profundidad del dispositivo debe ser reducida y al mismo tiempo se requiere un buen control de la dirección del haz luminoso.In the variant of Figure 6, the central part of the device is more extended outward, on the edge of the wall or ceiling This solution is particularly suitable for ceiling applications in which the depth of the device it must be reduced and at the same time a good control of The direction of the light beam.

Naturalmente, pueden llevarse a cabo numerosos cambios en la construcción y formas de realización de la invención previstas en la presente memoria, estando todos ellos comprendidos dentro del alcance de las siguientes reivindicaciones.Naturally, numerous can be carried out Changes in construction and embodiments of the invention provided herein, all of which are included within the scope of the following claims.
