ANTECEDENTES BACKGROUND
Cuando las necesidades hacen economizar en el consumo de energía eléctrica se tiende a reducir el consumo disminuyendo la potencia de las lámparas y tubos. Esto dificulta la visión, pudiendo provocar dolores de cabeza, fatiga en la visión y hasta accidentes por mala iluminación. Empresas fabricantes de LED de potencia están desarrollando siempre nuevos dispositivos con los que se logra no sólo prolongar la vida de la lámpara, sino que además consigue ahorro energético. When the needs make economize in the consumption of electrical energy, the consumption tends to be reduced by decreasing the power of the lamps and tubes. This makes vision difficult, causing headaches, fatigue in vision and even accidents due to poor lighting. Companies manufacturing LED power are always developing new devices with which not only prolong the life of the lamp, but also achieves energy savings.
Los LED de luz blanca son diodos azules que emiten luz a una longitud de onda de unos 460 nm, recubiertos de una capa de derivados de fósforo. El fósforo absorbe la luz azul y la remite a diferentes longitudes de onda en el espectro visible, generando luz blanca. Están basados en semiconductores de Nitruro de indio y galio.  White light LEDs are blue diodes that emit light at a wavelength of about 460 nm, coated with a layer of phosphorus derivatives. Phosphorus absorbs blue light and sends it to different wavelengths in the visible spectrum, generating white light. They are based on semiconductors of indium and gallium nitride.

El polo positivo del diodo se encuentra soldado al terminal de salida, ánodo, a través de un fino conductor metálico, normalmente de oro. El diodo se encuentra recubierto de una película del derivado de fósforo que le da una tonalidad amarillenta.

The diode cathode is directly connected to a small parabolic reflector that in turn serves as an output terminal. The positive pole of the diode is welded to the output terminal, anode, through a thin metallic conductor, usually gold. The diode is coated with a phosphorus derivative film that gives it a yellowish hue. The set is It is encapsulated in an epoxy resin of optical quality (high transparency) that serves as support, protection and focusing optics.
Una ventaja importante de la iluminación con LED es su bajo consumo, alrededor de 10 veces menos que el de un foco halógeno. Además, la vida útil de los LED también es superior al foco; durante el mismo período con la luz encendida, se tendrían que sustituir unas 16 veces el citado foco halógeno. Actualmente, el vapor de sodio de alta presión, de uso común en el alumbrado público de gran parte de Europa, brinda una eficacia de 85 lúmenes por vatio, la tecnología LED va camino de superar los 150 lúmenes por vatio, incrementándose esta cifra a medida que se progresa en el desarrollo de semiconductores. An important advantage of LED lighting is its low consumption, about 10 times less than that of a halogen bulb. In addition, the life of the LEDs is also greater than the focus; during the same period with the light on, the said halogen spotlight would have to be replaced about 16 times. Currently, high-pressure sodium vapor, commonly used in public lighting in much of Europe, provides an efficiency of 85 lumens per watt, LED technology is on its way to exceeding 150 lumens per watt, increasing this number as that progress is made in the development of semiconductors.
El mercurio utilizado en sistemas más antiguos de alumbrado implica grandes peligros medioambientales. Al contrarío que las lámparas de sodio, las lámparas LED no requieren un tiempo de arranque para llegar a sus niveles óptimos de luminosidad. Al mismo tiempo que se disminuye el consumo de energía y los costos generales de operación. La iluminación a través de diodos LED en las calles tiene el potencial, según los investigadores, de reducir la contaminación lumínica.  Mercury used in older lighting systems involves great environmental hazards. Unlike sodium lamps, LED lamps do not require a starting time to reach their optimum levels of brightness. At the same time that energy consumption and general operating costs are reduced. Lighting through LEDs on the streets has the potential, according to researchers, to reduce light pollution.
Los potentes LED que se encuentran en este momento en el mercado están en plenas condiciones para utilizarlos en luminarias de las calles ya que cumplen con los reglamentos estándar para niveles y uniformidad de luminancia, en comparación con otras tecnologías. Es decir, lo que se requiere es la uniformidad del alumbrado público, capaz de eliminar problemas de deslumbramiento, de excesiva concentración del haz luminoso y de visibilidad, mejorando la seguridad.  The powerful LEDs that are currently in the market are in full condition for use in street luminaires as they comply with the standard regulations for levels and uniformity of luminance, compared to other technologies. That is, what is required is the uniformity of street lighting, capable of eliminating problems of glare, excessive concentration of the light beam and visibility, improving safety.
Gracias a su mayor longevidad, los LED de farolas y semáforos no necesitan ser reemplazados con tanta frecuencia, disminuyendo las facturas en el alumbrado, atascos, incluso facilitando su sustitución.  Thanks to their greater longevity, the LED lamps and traffic lights do not need to be replaced as often, reducing bills in the lighting, traffic jams, even facilitating their replacement.
El alumbrado basado en LED ofrece el beneficio de una representación más natural de los colores que puede ayudar a mejorar la segundad. Los diodos permiten ajustar la temperatura del color a una aplicación de alumbrado público específica, que con las tecnologías de iluminación convencional no se dispone de esta alternativa. LED-based lighting offers the benefit of a more natural representation of colors that can help improve safety. The diodes allow you to adjust the color temperature to a street lighting application specific, that this alternative is not available with conventional lighting technologies.
Se conocen en el estado de la técnica cabezales de farola cuyo funcionamiento se base en LED. Es el caso por ejemplo délos cabezales comercializados por Joliet Technology, S. L, que consisten en cabezas de farolas para alumbrado público, utilizando LED, que se adaptan a la mayoría de las farolas existentes en el mercado. Estas cabezas de farola son de plástico, colocando módulos con los LED que radian de manera independiente. De este modo, Joliet utiliza cabezas defarola de plástico por un lado, e iluminación a través de LED por otro. Es decir, son elementos independientes, que pueden actuar uno sin el otro, por una parte las lámparas LED en cualquier otro sistema, y por otro lado, la cabeza de farola con otras lámparas. Este sistema no es estanco, pues los LED van en módulos atornillados y presenta rejillas para disipación de calor, de modo que en caso de lluvia o condiciones adversas en el exterior, daría problemas en su funcionamiento. Además, como sabemos, el aumento de temperatura durante el funcionamiento es el gran problema de la utilización de este tipo de lámparas LED en particular la región donde se sitúa la fuente. Esta cabeza de plástico no disipa el calor producido, sino que mantiene una elevada temperatura que provoca la deformación de la cabeza, por lo que no ha sido posible aplicarlo en la práctica  Lamp heads whose operation is based on LEDs are known in the state of the art. This is the case, for example, of the heads marketed by Joliet Technology, S. L, which consist of headlights for street lighting, using LEDs, which adapt to the majority of street lamps existing in the market.

This system is not waterproof, because the LEDs are screwed in modules and have grilles for heat dissipation, so that in case of rain or adverse conditions outside, it would cause problems in its operation. In addition, as we know, the increase in temperature during operation is the major problem of using this type of LED lamps in particular the region where the source is located. This plastic head does not dissipate the heat produced, but maintains a high temperature that causes deformation of the head, so it has not been possible to apply it in practice
En la actualidad se tiene el conocimiento de que la tecnología de generación de luz mediante diodos emisores de luz (LED, Ligh Emitting Diode) proporciona un ahorro de energía muy importante en comparación con el resto de tecnologías de iluminación existentes debido a que los dispositivos LED generan la luz a partir de energía eléctrica con mayor rendimiento en términos de lúmenes por vatio y con mayor calidad en términos de reproducción crómica. Además, tienen un tiempo de funcionamiento superior al resto de las lámparas del estado de la técnica. At present it is known that the technology of light generation by means of light emitting diodes (LED, Ligh Emitting Diode) provides a very important energy saving compared to the rest of existing lighting technologies because the LED devices they generate the light from electrical energy with greater performance in terms of lumens per watt and with higher quality in terms of chromatic reproduction. In addition, they have a longer operating time than the rest of the prior art lamps.
Debido a las ventajas señaladas, son numerosos los desarrollos realizados para resolver diferentes aplicaciones de iluminación mediante dispositivos LED. Una de las aplicaciones posibles es su utilización en luminarias de alumbrado público: áreas públicas urbanas, vfas públicas, parques, aparcamientos, etc. Las lámparas convencionales de alumbrado ofrecen valores de flujo luminoso muy elevados. Due to the advantages indicated, there are numerous developments to solve different lighting applications using LED devices. One of the possible applications is its use in street lighting luminaires: urban public areas, public roads, parks, parking lots, etc. Conventional lighting lamps offer very high luminous flux values.
Para conseguir valores equivalentes con dispositivos LED se requiere una potencia eléctrica muy superior a la de las lámparas LED de uso doméstico, aunque inferior a la de las lámparas de alumbrado convencionales. A pesar del alto rendimiento de la tecnología LED, el calor generado por las lámparas LED, unido al hecho de que éstas no pueden operar a temperaturas mayores de 80°C o 90°C, so pena de perder rendimiento y tiempo de vida, y a las limitaciones que presentan las luminarias convencionales para la evacuación del calor generado en su interior, hacen que no se hayan conseguido lámparas LED de sustitución para alumbrado que funcionen de forma suficientemente eficiente y fiable. To achieve equivalent values with LED devices, an electrical power much higher than that of domestic LED lamps is required, although lower than that of conventional lighting lamps. Despite the high performance of LED technology, the heat generated by LED lamps, together with the fact that they cannot operate at temperatures greater than 80 ° C or 90 ° C, under penalty of losing performance and life time, since The limitations presented by conventional luminaires for the evacuation of heat generated inside, mean that no replacement LED lamps for lighting have been achieved that work efficiently and reliably.
La tecnología LED requiere, además del propio dispositivo radiante LED, del empleo de un convertidor de alimentación que adapte la tensión de suministro, habitualmente alterna, a la requerida por ios dispositivos semiconductores LED, que como es sabido es la corriente continua. Las luminarias convencionales no disponen de dicho convertidor de alimentación, el cual hay que instalarlo dentro de la luminaria o bien dentro de la propia lámpara, opción esta última que es la más ventajosa en cuanto a simplicidad de instalación, pero que obliga al convertidor de alimentación a operar en condiciones de temperaturas elevadas, lo que dificulta el que pueda hacerlo de forma fiable. Existen invenciones que pretenden resolver los inconvenientes referidos, pero que no lo logran de forma satisfactoria o no son aplicables al uso en alumbrado. LED technology requires, in addition to the LED radiating device itself, the use of a power converter that adapts the supply voltage, usually alternating, to that required by the LED semiconductor devices, which, as is known, is direct current. Conventional luminaires do not have such a power converter, which must be installed inside the luminaire or inside the lamp itself, the latter option which is the most advantageous in terms of simplicity of installation, but which forces the power converter to operate in high temperature conditions, which makes it difficult for you to do so reliably. There are inventions that seek to solve the aforementioned problems, but that do not achieve it satisfactorily or are not applicable to lighting use.
En este sentido puede citarse la solicitud de patente internacional WO2011/135151, que describe una lámpara de sustitución que presenta como inconveniente principal el carecer de disipadores adecuados para evacuar el calor al exterior. Los disipadores que presenta son muy poco efectivos por encontrarse confinados en el interior de unos recintos bi-cónicos con mínima apertura al exterior. Otro inconveniente que presenta es que la luz que emiten los dispositivos LED no se radia directamente al exterior de la lámpara, sino que lo hace reflejada en unos reflectores cónicos metálicos susceptibles de sufrir oxidación y, por tanto, de ver mermadas sus propiedades ópticas. Además, la lámpara descrita carece de adaptador de alimentación integrado, lo que obliga a proveer de un adaptador de alimentación exterior. In this regard, the international patent application WO2011 / 135151 can be cited, which describes a replacement lamp that has as its main drawback the lack of adequate heatsinks to evacuate heat to the outside. The heatsinks it presents are very inefficient because they are confined inside bi-conical enclosures with minimal opening to the outside. Another drawback that presents is that the light emitted by LED devices is not radiated directly to the outside of the lamp, but it is reflected in metallic conical reflectors that can suffer oxidation and, therefore, of seeing its optical properties diminished. In addition, the lamp described lacks an integrated power adapter, which makes it necessary to provide an external power adapter.
También cabe citar la solicitud de patente estadounidense US2009/0267509, que describe una lámpara de sustitución en la que los elementos radiantes tipo LEO se encuentran confinados en el interior de una ampolla de vidrio, lo que impide la disipación del calor generado por los dispositivos LED. La luz se radia en una sola dirección, lo que también la hace inadecuada como lámpara de sustitución para alumbrado público.  It is also worth mentioning the US patent application US2009 / 0267509, which describes a replacement lamp in which the radiating elements type LEO are confined inside a glass ampoule, which prevents heat dissipation generated by LED devices . The light is radiated in only one direction, which also makes it unsuitable as a replacement lamp for street lighting.
Además puede citarse la solicitud de patente estadounidense US2010/0134046. Describe una solución para adaptar una luminaria convencional de alumbrado público a ia tecnología de iluminación LED, pero no puede considerarse una lámpara de sustitución por requerir un nivel de manipulación en la luminaria muy elevado: no se conecta al portalámparas existente y requiere anclajes mecánicos adicionales. In addition, US patent application US2010 / 0134046 may be cited. It describes a solution to adapt a conventional street lighting luminaire to LED lighting technology, but it cannot be considered a replacement lamp because it requires a very high level of manipulation in the luminaire: it does not connect to the existing lampholder and requires additional mechanical anchors.
La solicitud de patente estadounidense US2011/0134239, describe una lámpara de sustitución que radia en una sola dirección, por lo que no es utilizable en luminarias que requieren lámparas omnidireccionales. El elemento disipador no es modular, sino formado por un único bloque dispuesto sobre un panel de dispositivos LED, lo que hace que la superficie útil del disipador sea reducida. Además, la efectividad del disipador se ve muy comprometida por la ubicación que ocupa: entre el panel LED y el alimentador, elementos ambos que obstaculizan el movimiento del aire por el disipador.  US patent application US2011 / 0134239 describes a replacement lamp that radiates in only one direction, so it is not usable in luminaires that require omnidirectional lamps. The dissipative element is not modular, but formed by a single block arranged on a panel of LED devices, which makes the useful surface of the dissipator smaller. In addition, the effectiveness of the heatsink is greatly compromised by the location it occupies: between the LED panel and the feeder, both elements that hinder the movement of air through the heatsink.

Se caracteriza por que los módulos disipadores están configurados para ensamblar los módulos contiguos y simultáneamente realizar la fijación de la tarjeta de LEDs; quedando los diferentes módulos de refrigeración separados entre sí para permitir la circulación de aire entre ellos. Las tarjetas de LEDs presentan una configuración alargada. Los módulos disipadores presentan una configuración formada por sectores separados entre sí, para proporcionar una superficie de contacto muy amplia que favorece la evacuación del calor.
