Description

Luminaria LED LED luminaire

La presente invención se refiere a una luminaria LED que presenta notables características de novedad y actividad inventiva con respecto a lo anteriormente conocido. The present invention relates to an LED luminaire that has remarkable features of novelty and inventive activity with respect to the previously known.

Las luminarias a base de LED est�n sustituyendo actualmente a las luminarias de tipo tradicional, debido a los ahorros de energía que suponen. LED-based luminaires are currently replacing traditional type luminaires, due to the energy savings that they entail.

Uno de los inconvenientes de los LEDs es que generan un calor que ha de ser disipado para el buen funcionamiento del dispositivo. Como consecuencia, sustituir una bombilla por un LED de similares características lumínicas supone la necesidad de utilización de un voluminoso disipador met�lico con aletas para disipar el calor. Otro inconveniente es que los LEDs presentan un ángulo de proyección de la luz diferente al de las bombillas tradicionales, por lo que resulta necesaria la colocación de lentes frente al LED o placa de LEDs para obtener un ángulo operativo. One of the disadvantages of LEDs is that they generate heat that has to be dissipated for the proper functioning of the device. As a consequence, replacing a bulb with an LED with similar light characteristics implies the need to use a bulky metal heatsink with fins to dissipate heat. Another drawback is that the LEDs have a different angle of projection of light than traditional bulbs, so it is necessary to place lenses in front of the LED or LED plate to obtain an operating angle.

Una consecuencia de la necesidad de introducir un voluminoso disipador de calor y una óptica es que no es posible sustituir directamente el elemento lumínico de luminaria tradicional, tal como una farola o un fluorescente, por una luminaria LED. A consequence of the need to introduce a bulky heat sink and an optician is that it is not possible to directly replace the traditional luminaire light element, such as a lamppost or a fluorescent lamp, with an LED luminaire.

La presente invención tiene como objetivo dar a conocer luminarias basadas en una placa de luminaria que tiene como característica su extremada sencillez, que no es voluminosa y que permite la citada sustitución de elementos lumínicos en luminarias tradicionales ya existentes. The present invention aims to make luminaires based on a luminaire plate which has as its characteristic its extreme simplicity, which is not voluminous and which allows the mentioned replacement of luminous elements in existing traditional luminaires.

Para dar una solución a dicho problema, la presente invención utiliza una pluralidad de un tipo particular de LED, dispuestos regularmente sobre un disipador que es laminar. El tipo de LED y su disposición permite ahorrarse los disipadores de aletas voluminosos. Su tipo y disposición permite a su vez una utilidad sustitutiva sin necesidad del uso de lentes para focalizar el haz de luz generado. To give a solution to said problem, the present invention uses a plurality of a particular type of LED, regularly arranged on a heatsink that is laminar. The type of LED and its arrangement allows you to save bulky fin heatsinks. Its type and arrangement also allows a replacement utility without the use of lenses to focus the beam of light generated.

En particular, la presente invención comprende una luminaria de LEDs, del tipo que comprende un conjunto de LEDs y un disipador del calor generado por los citados LEDs, caracterizada porque comprende una placa met�lica que actúa como el disipador de calor de la luminaria, a la cual est� adherido un circuito impreso, y una pluralidad de LEDs tipo SMD (Surface Mounted Diode) encapsulados en resina semirr�gida, montados superficialmente sobre el circuito impreso, estando dichos LEDs dispuestos de manera regular en la citada placa. In particular, the present invention comprises a LED luminaire, of the type comprising a set of LEDs and a heat sink generated by said LEDs, characterized in that it comprises a metal plate that acts as the heat sink of the luminaire, to which a printed circuit is attached, and a plurality of SMD (Surface Mounted Diode) type LEDs encapsulated in semi-rigid resin, surface mounted on the printed circuit, said LEDs being arranged regularly on said board.

Preferentemente, y dado que sus elementos la hace innecesaria, la luminaria carece de lente alguna para redirigir el haz de luz generado por la pluralidad de LEDs. Preferably, and since its elements make it unnecessary, the luminaire lacks any lens to redirect the beam of light generated by the plurality of LEDs.

Dada sus ventajosas propiedades de transmisión de calor y pobres propiedades de transmisión de la electricidad, preferentemente, la placa met�lica est� realizada en aluminio. Given its advantageous heat transfer properties and poor electricity transmission properties, preferably, the metal plate is made of aluminum.

La presente invención puede materializarse en forma de luminaria compuesta únicamente por los elementos señalados, si bien también puede incluir el resto de elementos accesorios y/o est�ticos de la misma. Por ejemplo, puede comprender una carcasa plana, un difusor de luz plano y medios de conexión al suelo. También puede realizarse en forma de farola de alumbrado público. The present invention can be realized in the form of a luminaire composed only of the indicated elements, although it can also include the rest of the accessory and / or aesthetic elements thereof. For example, it may comprise a flat housing, a flat light diffuser and ground connection means. It can also be done in the form of street lighting.

Para una mejor comprensión de la invención se adjuntan, a título de ejemplo explicativo pero no limitativo, unos dibujos de una realización preferente de la presente invención: For a better understanding of the invention are attached, by way of explanatory but not limiting example, drawings of a preferred embodiment of the present invention:

La figura 1 muestra un una vista en planta superior de una luminaria según la presente invención. Figure 1 shows a top plan view of a luminaire according to the present invention.

La figura 2 muestra una vista en alzado de un detalle de un extremo de la luminaria de la figura 1. Figure 2 shows an elevation view of a detail of one end of the luminaire of Figure 1.

La figura 3 muestra una vista en perspectiva la luminaria de las figuras 1 y 2 con una carcasa para colocación en el techo. Figure 3 shows a perspective view of the luminaire of Figures 1 and 2 with a housing for ceiling placement.

La figura 4 muestra una vista en planta desde su parte inferior de una aplicación de la luminaria de las figuras 1 y 2 a una farola de alumbrado público. Figure 4 shows a plan view from its bottom of an application of the luminaire of Figures 1 and 2 to a streetlamp.

La figura 5 muestra una vista en perspectiva de otra realización de luminaria según la presente invención, en una aplicación sustitutiva de fluorescentes. Figure 5 shows a perspective view of another embodiment of luminaire according to the present invention, in a fluorescent replacement application.

Las figuras 1 y 2 muestran una realización consistente en una placa -1- circular, que realización la función de disipador de calor y sobre la que se ha adherido un substrato de circuito impreso -2-. Sobre el circuito impreso se han colocado, en disposición regular y circular concéntrica, una pluralidad de LEDs -3-. Cada siete LEDs se ha colocado una resistencia -7-. Dos cables -5-, -6- alimentan el circuito y los LEDs. Figures 1 and 2 show an embodiment consisting of a -1-circular plate, which performed the function of heat sink and on which a printed circuit substrate -2- has adhered. A plurality of LEDs -3- have been placed on the printed circuit in a regular and concentric circular arrangement. A resistance -7- has been placed every seven LEDs. Two wires -5-, -6- feed the circuit and the LEDs.

Como se observa, los LEDs -3-utilizados son de tipo SMD (Surface Mounted Diode) encapsulados en resina semirr�gida montados superficialmente sobre el circuito impreso. El ángulo de rayo del haz de luz emitida, tal y como se observa en la figura 2, es de 120�. Por esta razón, una vez dispuesta la pluralidad de LEDs en disposición regular, no requieren de la colocación de una lente para su correcto funcionamiento. Los ejemplos mostrados en las figuras 1 a 6 carecen de lentes, as� como de disipadores de calor voluminosos y/o con aletas. As can be seen, the LEDs -3-used are of the SMD (Surface Mounted Diode) type encapsulated in semi-rigid resin mounted superficially on the printed circuit. The beam angle of the emitted beam of light, as seen in Figure 2, is 120�. For this reason, once the plurality of LEDs are arranged in regular arrangement, they do not require the placement of a lens for proper operation. The examples shown in Figures 1 to 6 lack lenses, as well as bulky and / or finned heat sinks.

La figura 3 muestra la luminaria de las figuras 1 y 2 a la que se ha añadido una carcasa -8- para su unión a un techo. No se han mostrado los medios de unión al techo, que podrán ser, por ejemplo, de tipo estándar. En la figura 3 no se ha mostrado ningún difusor de la luz, por ejemplo una placa translúcida, por no ser necesaria en todas las aplicaciones. Figure 3 shows the luminaire of Figures 1 and 2 to which a housing -8- has been added for attachment to a ceiling. The means for joining the ceiling have not been shown, which may be, for example, of the standard type. In Figure 3 no light diffuser has been shown, for example a translucent plate, because it is not necessary in all applications.

La figura 4 muestra desde un punto de vista situado en el suelo, la placa de las figuras 1 y 2 aplicada a una farola -11- de alumbrado público ya existente. En este caso, la placa sustituye, directamente, la luminaria o elemento lumínico de tipo convencional. La figura muestra una vista inferior desde el suelo, en la que se puede observar la placa. Figure 4 shows from a viewpoint located on the ground, the plate of Figures 1 and 2 applied to a streetlight -11- of existing street lighting. In this case, the plate directly replaces the luminaire or conventional light element. The figure shows a bottom view from the ground, in which the plate can be seen.

La figura 5 muestra un ejemplo con otra realización de la presente invención con similares elementos pero con una forma geométrica distinta. Los elementos iguales o similares a los mostrados en las anteriores figuras han sido marcados con idénticos numerales y no ser�n explicados en profundidad. En este caso la placa -1- es de forma rectangular y los LEDs -3- se distribuyen regularmente de a lo largo de un rectángulo. La carcasa -8- es asimismo plana y rectangular. Los LEDs -3- quedan tapados por un difusor -9- que puede tratarse, por ejemplo, de una lámina traslúcida de material plástico. Figure 5 shows an example with another embodiment of the present invention with similar elements but with a different geometric shape. The same or similar elements to those shown in the previous figures have been marked with identical numerals and will not be explained in depth. In this case the plate -1- is rectangular in shape and the LEDs -3- are distributed regularly along a rectangle. The housing -8- is also flat and rectangular. The LEDs -3- are covered by a diffuser -9- which can be, for example, a translucent sheet of plastic material.

Como se comprender�, la presente invención no quedar� limitada a la realización mostrada, que tiene simplemente carácter de ejemplo y se podrán introducir múltiples variaciones que quedarán evidentes para los técnicos en la materia después de la lectura de la presente descripción y reivindicaciones que se adjuntan y observación de los correspondientes dibujos. Dichas variantes quedarán comprendidas dentro del ámbito de la presente invención siempre que est�n incluidas en el alcance de las reivindicaciones siguientes. As will be understood, the present invention will not be limited to the embodiment shown, which is simply exemplary and multiple variations may be introduced that will become apparent to those skilled in the art after reading the present description and claims that are Attached and observation of the corresponding drawings.
