La presente invención se engloba dentro del sector técnico de la iluminación, y más concretamente se refiere a lámparas que utilizan para la sustitución en las luminarias de alumbrado exterior existentes que utilizan lámparas de vapor de sodio o de mercurio.  The present invention falls within the technical sector of lighting, and more specifically refers to lamps that are used for replacement in existing outdoor lighting luminaires that use sodium or mercury vapor lamps.

Antecedentes de la invención Background of the invention

Normalmente las lámparas empleadas en luminarias de alumbrado exterior conocidas en la actualidad emplean como elementos emisores de luz a lámparas incandescentes, halógenas, de vapor de Sodio o Mercurio, tubos fluorescentes, etc. , estos elementos emisores además de su relativa corta duración, tienen un consumo energético importante. Como solución, en los últimos tiempos están apareciendo en el mercado bombillas de bajo consumo que si bien han reducido el consumo de energía eléctrica, aún están lejos de una eficiencia energética razonable.  Normally, the lamps used in exterior lighting luminaries known today use light emitting elements such as incandescent, halogen, sodium or mercury vapor lamps, fluorescent tubes, etc. In addition to their relative short duration, these emitting elements have an important energy consumption. As a solution, in recent times low-energy light bulbs are appearing on the market, which although they have reduced the consumption of electric energy, they are still far from reasonable energy efficiency.

Por otra parte, y en referencia al estado de la técnica, debe mencionarse que el solicitante desconoce la existencia de ninguna otra invención que, con un objetivo similar, presente unas características técnicas, estructurales o de configuración, semejantes a las que presenta el dispositivo que aquí se propone.  On the other hand, and in reference to the state of the art, it should be mentioned that the applicant is unaware of the existence of any other invention that, with a similar objective, has technical, structural or configuration characteristics, similar to those presented by the device that here it is proposed.

Descripción de la invención Description of the invention

La presente invención se refiere a una lámpara de sustitución microled que comprende un casquillo conectado a una carcasa inferior a continuación de la que se dispone un disipador. Más concretamente, la lámpara se caracteriza porque el disipador tiene forma semicil índ rica, con una cara plana perpendicular a la base mayor de la carcasa, disponiéndose en dicha cara plana un módulo microled. The present invention relates to a microled replacement lamp comprising a socket connected to a lower housing following which a heatsink is provided. More specifically, the lamp is characterized in that the heatsink has an indic semicilous shape, with a flat face perpendicular to the main base of the housing, a microled module being provided on said flat face.

En el interior de la carcasa inferior se dispone un arrancador que comprende una fuente de alimentación y un inversor, cuya misión es transformar la corriente alterna que proviene de la red a 230 VAC a corriente continua a 36 VDC.  Inside the lower housing there is a starter comprising a power supply and an inverter, whose mission is to transform the alternating current that comes from the network to 230 VAC to direct current at 36 VDC.

De esta forma, la lámpara presenta una configuración vertical que permite que el emisor de luz (módulo microled) quede orientado hacia abajo, y de este modo cumplir el objetivo de iluminar la superficie que se encuentra bajo la luminaria en la que se instale.  In this way, the lamp has a vertical configuration that allows the light emitter (microled module) to face down, and thus fulfill the objective of illuminating the surface under the luminaire in which it is installed.

Además, se consigue solventar los inconvenientes más arriba descritos en lo que se refiere a la vida útil y consumo, al utilizar las lámparas de sustitución objeto de la presente invención microieds. De forma más concreta, esencialmente la invención se basa en la incorporación de microieds en las lámparas de sustitución de luminarias urbanas ya existentes, las cuales se podrán utilizar sin problemas en dichas luminarias gracias a la incorporación de un arrancador. Por lo tanto, se podrían utilizar las luminarias ya situados en las ciudades y poblaciones, sustituyendo únicamente las lámparas sin necesidad de sustituir o modificar ninguno de los demás componentes de la luminaria, consiguiendo un ahorro energético, que aplicado a la red eléctrica española supondrá una reducción de consumo eléctrico considerable y por consiguiente un gran ahorro económico.  In addition, it is possible to solve the drawbacks described above in regard to the useful life and consumption, by using the replacement lamps object of the present invention microieds. More specifically, essentially the invention is based on the incorporation of microieds in the replacement lamps of existing urban luminaires, which can be used without problems in said luminaires thanks to the incorporation of a starter. Therefore, the luminaires already located in cities and towns could be used, replacing only the lamps without replacing or modifying any of the other components of the luminaire, achieving energy savings, which applied to the Spanish electricity grid will mean considerable reduction of electricity consumption and therefore a great economic saving.

Descripción de los dibujos Description of the drawings

Para una mejor interpretación de la invención se acompaña la presente memoria descriptiva de unos dibujos en los que se ilustra, a título de ejemplo no limitativo, una forma de realización preferida del objeto de la invención, según los principios de las reivindicaciones.  For a better interpretation of the invention, the present specification is accompanied by drawings in which, by way of non-limiting example, a preferred embodiment of the object of the invention is illustrated, according to the principles of the claims.

En dichos dibujos:  In these drawings:

La figura 1 representa una vista en perspectiva de una de las lámparas de sustitución objeto de la presente invención. Descripción de un ejemplo de realización de la invención Figure 1 represents a perspective view of one of the replacement lamps object of the present invention. Description of an embodiment of the invention

Según se puede apreciar en figura 1 , y de acuerdo con la numeración adoptada en ella, se ha representado una lámpara de sustitución microled que constituye una realización preferente aunque no limitativa de la invención.  As can be seen in Figure 1, and according to the numbering adopted therein, a microled replacement lamp has been represented which constitutes a preferred but not limiting embodiment of the invention.

La lámpara comprende un casquillo (1 ) del tipo de rosca estándar E40, conectado a una carcasa inferior (2) del que parte un disipador (3) de calor que está fabricado en aluminio o un material disipador de similares características, el cual tiene una forma semicilíndrica con una pluralidad de aletas disipadoras en su contorno exterior. El disipador (3) está orientado de forma que se sitúa perpendicularmente a la base mayor (5) de la carcasa (2), la cuai tiene una forma aproximadamente troncocónica de generatriz curva, esta ndo conectada su base menor al casquillo (1 ). Por tanto la cara plana (4) del disipador (3) queda situada perpendicularmente a la carcasa (2) y el casquillo (1 ), para que, de esta forma, dicha cara plana enfoque hacia abajo cuando se ha instalado la lámpara en la luminaria. Dicha configuración obedece a que en la cara plana (4) se sitúa un módulo microled (6) formado por una pluralidad de microleds, para que el haz de luz pueda incidir en dirección al suelo.  The lamp comprises a socket (1) of the standard thread type E40, connected to a lower housing (2) from which a heat sink (3) is made of aluminum or a dissipating material of similar characteristics, which has a semi-cylindrical shape with a plurality of dissipating fins on its outer contour. The heatsink (3) is oriented so that it is located perpendicularly to the major base (5) of the housing (2), which has an approximately conical shape of a curved generatrix, its minor base is connected to the socket (1). Therefore the flat face (4) of the heatsink (3) is located perpendicularly to the housing (2) and the socket (1), so that, in this way, said flat face is facing down when the lamp has been installed in the luminary. Said configuration is due to the fact that a microled module (6) formed by a plurality of microleds is located on the flat face (4), so that the light beam can influence the ground.

Los detalles, las formas, las dimensiones y demás elementos accesorios, así como los materiales empleados en la fabricación del accesorio de la invención podrán ser convenientemente sustituidos por otros que sean técnicamente equivalentes y no se aparten de la esencialidad de la invención.  The details, shapes, dimensions and other accessory elements, as well as the materials used in the manufacture of the accessory of the invention may be conveniently substituted by others that are technically equivalent and do not depart from the essentiality of the invention.

La constitución interna de la lámpara es como se describe a continuación: del módulo microled (6) parten dos cables, positivo y negativo (no representados en la figura) que discurren a través del disipador (3) de calor y que se conexionan directamente al casquillo (1 ). Dado que para que los microleds funcionen adecuadamente tiene que ser alimentados a corriente continua a 36 VDC y la corriente proveniente de la red eléctrica viene en corriente alterna a 230 VAC, se dispondrá un arrancador (no representado) en el interior de la carcasa (2) que comprende una fuente de alimentación y un inversor.  The internal constitution of the lamp is as described below: from the microled module (6), two wires, positive and negative (not shown in the figure), run through the heat sink (3) and are connected directly to the cap (1). Since in order for the microleds to function properly, they must be supplied with a direct current at 36 VDC and the current coming from the mains comes in alternating current at 230 VAC, a starter (not shown) will be provided inside the housing (2 ) comprising a power supply and an inverter.
