OBTETO DE LA INVENCIÓNOBTAIN OF THE INVENTION
La presente invención se refiere a una luminaria, especialmente concebida para el alumbrado público, si bien puede ser obviamente implantada en otro tipo de sistemas de iluminación.The present invention relates to a luminaire, especially designed for public lighting, although it can obviously be implanted in other types of lighting systems.
El objeto de la invención es proporcionar una luminaria sumamente efectiva, con un reducido consumo eléctrico, y con una larga vida útil.The object of the invention is to provide a highly effective luminaire, with reduced electrical consumption, and with a long service life.
Es asimismo objeto de la invención proporcionar una luminaria mediante la cual se evite la contaminación lumínica producida por el reflejo de la luz hacia arriba que se produce en las luminarias convencionales.It is also the object of the invention to provide a luminaire whereby light pollution caused by the reflection of the upward light produced in conventional luminaires is avoided.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
En el ámbito de aplicación práctica de la invención, son conocidos muy diversos tipos de luminarias, siendo las más utilizadas hasta la fecha aquellas que incorporan una bombilla de sodio, que si bien cumplen satisfactoriamente la función para la que han sido previstas, presentan un elevado consumo eléctrico, y una vida útil que sería deseable incrementar, así como la contaminación que produce el sodio como residuo una vez finaliza la vida de la bombilla y la elevada contaminación lumínica que produce el sodio. Tratando de obviar esta problemática son conocidas luminarias que están constituidas a partir de una pluralidad de diodos led, los cuales, debido a su reducido consumo, presentan un consumo eléctrico total del conjunto sensiblemente menor que el de las bombillas de sodio junto con la facilidad de reciclado de los leds.In the practical field of application of the invention, very different types of luminaires are known, the most used to date being those that incorporate a sodium bulb, which, while satisfactorily fulfilling the function for which they have been provided, have a high electricity consumption, and a useful life that would be desirable to increase, as well as the pollution that sodium produces as waste once the life of the bulb ends and the high light pollution that sodium produces. Trying to obviate this problem are known luminaries that are constituted from a plurality of LEDs, which, due to their reduced consumption, have a total electrical consumption of the set significantly less than that of sodium bulbs together with the ease of LED recycling.
El problema que presentan este tipo de luminarias es que para conseguir un nivel de iluminación aceptable es necesario la participación de un gran número de diodos en las mismas, lo que complica y encarece la estructura del dispositivo.The problem with this type of luminaires is that in order to achieve an acceptable level of illumination it is necessary to involve a large number of diodes in them, which complicates and increases the structure of the device.
Igualmente cabe citar el problema de la contaminación lumínica de este tipo de luminarias, que se produce debido al reflejo de la luz en sentido ascendente sobre la carcasa del dispositivo.It is also worth mentioning the problem of light pollution of this type of luminaires, which occurs due to the reflection of the upward light on the device housing.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La luminaria que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, de manera que basándose en la utilización de diodos led, merced a la especial estructuración de la misma se consigue que para un mismo grado de iluminación se reduzca sensiblemente la participación de diodos led, y consecuentemente el consumo eléctrico del dispositivo.The luminaire that the invention proposes solves in a fully satisfactory manner the above-mentioned problem, so that based on the use of LEDs, thanks to the special structuring thereof, it is achieved that for the same degree of illumination the participation of LEDs, and consequently the electrical consumption of the device.
Para ello, y de forma más concreta, la luminaria de la invención parte de la estructura convencional de una luminaria a base de leds, en la que participa una carcasa abierta inferiormente, en cuyo seno se establece una placa de circuito impreso sobre el que se establecen convenientemente distribuidos una pluralidad de diodos led, alimentados a través del correspondiente circuito asociado a un transformador, con la particularidad de que sobre cada diodo se establece una lente formal y dimensionalmente adecuada para distribuir la luz únicamente hacia abajo, evitando la contaminación lumínica.To do this, and more specifically, the luminaire of the invention starts from the conventional structure of a LED-based luminaire, in which a lower open housing participates, in which a printed circuit board is established on which conveniently establish a plurality of diodes led, fed through the corresponding circuit associated with a transformer, with the particularity that on each diode a formal and dimensionally adequate lens is established to distribute the light only downwards, avoiding light pollution.
Debido al efecto de las citadas lentes, el área de iluminación se ve considerablemente aumentado respecto a las luminarias convencionales a base de leds, de manera que el distanciamiento entre luminarias puede ser mayor, al ser mayor dicho área de iluminación, con el consecuente ahorro económico que ello supone, o bien, para un mismo grado de iluminación el número de diodos que serán necesarios que participen en la luminaria se verá reducido, con el consecuente ahorro económico que de ello se deriva.Due to the effect of the aforementioned lenses, the lighting area is considerably increased with respect to conventional LED-based luminaires, so that the distance between luminaires can be greater, since said lighting area is greater, with the consequent economic savings that this means, or, for the same degree of illumination the number of diodes that will be necessary to participate in the luminaire will be reduced, with the consequent economic savings derived from it.

Figure 3.- Shows, finally, a view similar to that of the figure, but corresponding to a detail in longitudinal section.
REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas puede observarse como la luminaria que la invención propone parte, como es convencional en cualquier luminaria a base de diodos led, de una carcasa (1), formal y dimensionalmente adecuada para albergar en su seno a un circuito impreso (2), sobre el que se establecen convenientemente distribuidos una pluralidad de diodos led (3) alimentados eléctricamente a través de los correspondientes terminales de conexión (4), placa de circuito impreso (2) que estará asistida por el correspondiente transformador para la correcta alimentación eléctrica de los mismos, presentando la citada carcasa (1) la clásica ventana (5) sobre su cara inferior a través de la que se proyecta la luz emitida por el dispositivo, ventana (5) asistida por una lámina transparente (6) de cristal o material similar, contando la citada carcasa con medios (7) de fijación al poste o elemento de que se trate.In view of the aforementioned figures, it can be seen how the luminaire that the invention proposes, as is conventional in any LED-based luminaire, of a housing (1), formally and dimensionally suitable for housing a printed circuit (2), on which a plurality of LED diodes (3) electrically powered through the corresponding connection terminals (4), printed circuit board (2) that will be assisted by the corresponding transformer for the correct transformer are conveniently distributed Power supply thereof, the said housing (1) presenting the classic window (5) on its lower face through which the light emitted by the device is projected, window (5) assisted by a transparent sheet (6) of glass or similar material, said casing counting with means (7) for fixing to the post or element in question.
Pues bien, de acuerdo ya con la invención, sobre cada diodo (3) se dispone una lente (8), con una geometría tal que permite distribuir la luz únicamente hacia abajo, proyectando la luz irradiada con la máxima eficacia sobre el área a iluminar, de manera que se evita que la luz sea reflejada hacia arriba como sucede en las luminarias convencionales, evitando la contaminación lumínica, reduciendo el consumo eléctrico y aumentando el área de iluminación.Well, according to the invention, on each diode (3) there is a lens (8), with a geometry that allows the light to be distributed only downwards, projecting the irradiated light with maximum efficiency on the area to be illuminated , so that the light is prevented from being reflected upwards as in conventional luminaires, avoiding light pollution, reducing electricity consumption and increasing the lighting area.
Así pues, y con este sistema, una farola para una altura de 8 metros, cuyo equivalente en sodio son 15Ow, se disminuye su consumo hasta los 80 w aproximados, por los más de 10Ow de una luminara a base de leds convencional, con una larga vida útil, permitiendo implantar unas farolas con respecto de otras a una distancia mayor, debido al aumento del área de iluminación anteriormente citado, del orden de 40-50 metros, frente a los 30 metros máximos entre farolas con luminarias convencionales.So, and with this system, a lamppost for a height of 8 meters, whose sodium equivalent is 15Ow, its consumption is reduced to approximately 80w, by more than 10Ow of a conventional LED-based luminaire, with a long service life, allowing to install some lampposts with respect to others at a distance greater, due to the increase in the aforementioned lighting area, of the order of 40-50 meters, compared to the maximum 30 meters between street lamps with conventional luminaires.
Esta especial estructuración permite igualmente aumentar la distancia con respecto al suelo de la luminaria, hasta una altura de más de 16 metros. This special structuring also allows increasing the distance from the floor of the luminaire, to a height of more than 16 meters.
