Description

Soporte para diodo luminiscente utilizable en lamparitas y linternas conmutadas mediante cierre de bayoneta.Light-emitting diode support usable in Lamps and switched lanterns by bayonet closure.

Object of the invention

La presente invención se refiere a un soporte para diodo luminiscente utilizable en lamparitas y linternas conmutadas mediante cierre de bayoneta.The present invention relates to a support for luminescent diode usable in lamps and lanterns switched by bayonet closure.

Background of the invention

En la actualidad se conocen unas lamparitas de acumulación de placton constituidas por un cuerpo que contiene unas pilas y una óptica que es atravesada por la luz, y que sirven como señuelo para propiciar la pesca.At present, some light bulbs are known accumulation of placton constituted by a body that contains some batteries and an optic that is pierced by light, and that serve as lure to encourage fishing.

Por ejemplo, el modelo de utilidad 292.729, referente a una veleta luminosa para pesca nocturna, tiene una constitución a base de dos cuerpos acoplados desmontablemente entre sí, uno de los cuales presenta un alojamiento para una pila y un elemento luminiscente o diodo LED, siendo transparente y/o translúcido en la zona donde va el diodo. En el mismo la desconexión se realiza abriendo el cuerpo y cambiando la posición de la pila, polarizando inversamente el diodo. Esto tiene el inconveniente de que la apertura de la veleta perjudica la estanqueidad, y que la polarización inversa del diodo produce a la larga la descarga de la pila por corriente de polarización inversa.For example, utility model 292.729, referring to a light weather vane for night fishing, it has a constitution based on two bodies detachably coupled between yes, one of which presents a housing for a battery and a luminescent element or LED, being transparent and / or translucent in the area where the diode goes. In it the disconnection is done by opening the body and changing the position of the battery, polarizing the diode inversely. This has the disadvantage that the opening of the weather vane harms the tightness, and that the reverse polarization of the diode produces the long battery discharge by polarization current inverse

Por otra parte también se conoce el modelo de utilidad 200101124, referente a una linterna de reclamo para pesca, con una constitución similar: cuerpo receptor de pilas y de un LED, en el cual la conmutación del LED se realizaba por medio de un conmutador magnético, concretamente una ampolla-red, evitando la apertura de la linterna y perjuicio para la estanqueidad y la descarga de las pilas por corriente de polarización inversa del diodo. El inconveniente de esta realización consiste en que los medios de conmutación resultan caros y tienen poca fiabilidad. Otro inconveniente de esta lamparita es que no dispone de una resistencia limitadora de la corriente circulante por el diodo, lo que equivale en la práctica a cortocircuitar los polos de la pila y ocasionar su descarga rápida y/o destrucción del diodo. Esto intenta subsanarse intercalando en el circuito de alimentación del diodo LED otro diodo de corriente constante, que mantiene ésta en valores estables en un intervalo de voltaje, pero no protege al LED de los picos de corriente que se dan en la conmutación, y que acortan su vida útil.On the other hand, the model of utility 200101124, referring to a claim lantern for fishing, with a similar constitution: receiver body of batteries and an LED, in which the switching of the LED was carried out by means of a magnetic switch, specifically a blister-net, avoiding the opening of the flashlight and damage to the tightness and discharge of the batteries by reverse polarization current of the diode. The inconvenience of this embodiment consists in that the switching means result expensive and have little reliability. Another drawback of this Lamparita is that it does not have a limiting resistance of the current flowing through the diode, which is equivalent in practice to short circuit the battery poles and cause rapid discharge and / or destruction of the diode. This tries to correct itself by inserting The power circuit of the LED diode another current diode constant, which keeps it stable at a range of voltage, but does not protect the LED from current spikes they give in the commutation, and that shorten their useful life.

También se conoce el modelo de utilidad 200300632, referente a una lamparita para la acumulación de placton, con una constitución general parecida a la de cualquier linterna, con un cuerpo para pilas y una óptica, aunque en este caso la particularidad en la conmutación consiste en que el cuerpo y tapa se acoplan mediante un cierre de bayoneta, y que se aprovecha el giro de este cierre para la conmutación, con una posición intermedia de desconexión, otra extrema de cierre y conexión, y otra extrema opuesta de desacoplamiento entre el cuerpo y la óptica, para apertura de la lamparita.The utility model is also known 200300632, referring to a lamp for the accumulation of placton, with a general constitution similar to that of any flashlight, with a body for batteries and an optic, although in this case the particularity in switching is that the body and cover are coupled by a bayonet closure, and that take advantage of the rotation of this closure for switching, with a intermediate position of disconnection, another extreme of closing and connection, and another extreme opposite of decoupling between the body and optics, for opening the lamp.

Este modelo, del mismo solicitante que la presente solicitud, implementa la conmutación por giro mediante la participación de un soporte en forma de disco que incluye un rehundido para una placa de circuito impreso que monta el diodo LED, fijándose este disco mediante muelles y tornillos en la óptica, y presentando la placa de circuito impreso unas pistas que configuran unos contactos para los electrodos de las pilas, de modo que al girar a tope el cierre de bayoneta se polariza el diodo en directa, emitiendo luz, mientras que en posiciones intermedias del cierre previas a su apertura el diodo queda sin polarizar y por tanto sin emitir luminiscencia ni polarizarse inversamente, consiguientemente sin consumo alguno de la energía almacenada en las pilas.This model, from the same applicant as the present request, implements turn switching by means of participation of a disk-shaped support that includes a recessed for a printed circuit board that mounts the diode LED, fixing this disk by means of springs and screws in the optics, and presenting the printed circuit board some clues that set up contacts for battery electrodes, so that when turning the bayonet lock, the diode is polarized in direct, emitting light, while in intermediate positions of the closing before opening the diode remains unpolarized and by both without emitting luminescence or polarizing inversely, consequently without any consumption of the energy stored in the batteries

Esta lamparita tampoco tiene previstos medios de limitación de la intensidad circulante por el diodo, con efectos parecidos a los casos anteriores.This lamp also has no means of limitation of the current flowing through the diode, with effects similar to the previous cases.

En todos los casos, además, debido al uso extremadamente duro, sometido a golpes y ambientes húmedos y salitrosos de la lamparita o reclamo, la manipulación manual del LED durante la fabricación (apertura de patillas, etcétera) se acorta su vida operativa.In all cases, in addition, due to use extremely hard, subjected to shocks and humid environments and salitrous of the lamp or claim, the manual manipulation of LED during manufacturing (pin opening, etc.) is shortens its operational life.

Los inconvenientes mencionados se subsanan mediante el soporte para diodo LED de la invención.The mentioned problems are corrected by means of the LED diode holder of the invention.

Description of the invention

El soporte para diodo LED de la invención sirve de una manera óptima para alargar enormemente la vida útil, tanto del diodo, como de las pilas que lo alimentan.The LED diode holder of the invention serves in an optimal way to greatly extend the service life, both of the diode, as of the batteries that feed it.

De acuerdo con la invención, el soporte es del tipo descrito en los antecedentes: un disco que se fija mediante muelles y tornillos a la óptica de la lamparita, incorpora un rehundido para alojar la placa de circuito impreso que monta el LED y cuyas pistas constituyen unos electrodos que conmutan el LED al girar el cierre de bayoneta mediante el que se acopla la óptica en el cuerpo que contiene las pilas.According to the invention, the support is of the type described in the background: a disk that is fixed by springs and screws to the optic of the lamp, incorporates a recessed to accommodate the printed circuit board that mounts the LED and whose tracks constitute electrodes that switch the LED to rotate the bayonet closure by which the optics are coupled in the body that contains the batteries.

La mejora que la invención propone consiste en montar en primer lugar una resistencia limitadora de la corriente circulante por el diodo, especialmente acusada en la conexión (encendido) del mismo, prolongando su vida útil. Además, dado que la resistencia se tiene que montar preferentemente en la misma cara de la placa que monta el LED porque la opuesta implementa las pistas que discurren por los electrodos de las pilas, es necesario improvisar un cajeado o rehundido adicional en el disco para alojar esta resistencia.The improvement proposed by the invention consists in first mount a current limiting resistor circulating through the diode, especially accused in the connection (on) of it, prolonging its useful life. Also, since the resistance must preferably be mounted on the same face of the plate that mounts the LED because the opposite implements the tracks that run through the electrodes of the batteries, it is necessary improvise an additional recess or recess in the disk to accommodate this resistance

El segundo lugar, se propone alargar la vida del diodo no manipulándolo en el premontaje, insertando las patillas en los orificios previstos en la placa de circuito impreso y cizallando al ras una vez realizada esta inserción. Por ello es necesario que estos orificios estén metalizados internamente con el fin de que la soldadura fije por el interior del orificio las patillas del diodo.The second place is to extend the life of the diode not manipulating it in the preassembly, inserting the pins in the holes provided on the printed circuit board and Shearing flush after this insertion. That's why it is it is necessary that these holes be internally metallized with the so that the welding fixes inside the hole the diode pins.

Description of a practical embodiment of the invention

El soporte 1 de la invención está constituido por un disco 2 de material aislante, dotado en una de sus caras 3 de un cajeado 4 para alojar una placa 5 de circuito impreso que monta un diodo luminiscente 6 LED, así como una resistencia eléctrica 7 que actúa como limitadora de la corriente, especialmente de los picos que se producen en la conmutación del diodo, alargando su vida útil y prolongando la duración de las baterías.The support 1 of the invention is constituted by a disc 2 of insulating material, provided on one of its faces 3 of a recess 4 to accommodate a printed circuit board 5 that mounts a 6 LED light emitting diode, as well as an electric resistance 7 which acts as a current limiter, especially for peaks that occur in the switching of the diode, extending its shelf life and prolonging battery life.

Esta resistencia sobresale físicamente de la placa por la cara de montaje, por lo que está previsto un cajeado suplementario 8 en el disco 2 para su alojamiento.This resistance physically protrudes from the plate on the mounting face, so a recess is planned Supplementary 8 on disk 2 for accommodation.

La placa 5 incorpora unos orificios 9 de inserción de las patillas 10 del LED, las cuales tienen la particularidad que estar cortadas al ras con la superficie de la placa una vez colocado el diodo, con el fin de evitar manipulaciones de las patillas en el premontaje (apertura, doblado), operaciones que reduce la vida útil del diodo.The plate 5 incorporates holes 9 of insertion of the pins 10 of the LED, which have the particularity to be cut flush with the surface of the plate once the diode is placed, in order to avoid pin manipulations in the preassembly (opening, bent), operations that reduce the life of the diode.

Debido a esto, y para que el diodo quede oportunamente fijado por las soldaduras correspondientes, los orificios 9 van metalizados internamente.Because of this, and so that the diode is duly fixed by the corresponding welds, the holes 9 are internally metallized.

El disco tiene un orificio centrado 11 en correspondencia con los orificios 6 de la placa 5 cuando está alojada en su cajeado, para el paso de las patillas 10. Por la cara opuesta a la del montaje del LED y resistencia, la placa 5 tiene configuradas unas pistas 12 que constituyen unos electrodos de conexión de las pilas de alimentación, no representadas.The disc has a hole centered 11 in correspondence with holes 6 on plate 5 when it is housed in its pocket, for the passage of the pins 10. On the face opposite to the LED assembly and resistance, plate 5 has configured tracks 12 that constitute electrodes of connection of the power batteries, not shown.

La geometría de estas pistas es la adecuada para establecer la conexión del LED al girar el disco y entrar en contacto con los electrodos de las pilas. Este giro es posible gracias al cierre de bayoneta implementado entre la óptica y el cuerpo de la lamparita, ya que el soporte está solidarizado a la óptica, y las pilas contenidas en el cuerpo. Se considera como ángulo ideal para la conexión del LED unos 25º antes del tope de cierre, permitiendo a continuación ángulos al cierre de bayoneta antes de su apertura de unos 115º en los cuales el diodo no luce por no estar polarizado, y sin pérdida de energía en las pilas.The geometry of these tracks is adequate for establish the LED connection when turning the disc and entering contact with battery electrodes. This turn is possible. thanks to the bayonet closure implemented between the optics and the body of the lamp, since the support is in solidarity with the optics, and the batteries contained in the body. It is considered as ideal angle for the LED connection about 25º before the top of closure, then allowing angles to bayonet closure before its opening of about 115º in which the diode does not shine for not being polarized, and without loss of energy in the batteries

El soporte 1 va montado de modo basculante en la óptica 13, la cual no es objeto de la presente invención, e implementa los medios necesarios para el cierre de bayoneta. Este montaje basculante se materializa por medio de sendos muelles 14 opuestos intercalados entre el soporte y la óptica, y unos tornillos 15 que, atravesando unos orificios 16 del disco fijan con la necesaria holgura el disco a la óptica, incorporando el disco unos cajeados 17 para el asiento de los muelles.The support 1 is mounted in a tilting way in the optics 13, which is not the subject of the present invention, and implements the necessary means for bayonet closure. This tilting assembly is materialized by means of two springs 14 opposites interspersed between the support and the optics, and about screws 15 which, through holes 16 of the disc, fix with the necessary slack disc to optics, incorporating the disc a few recesses 17 for the spring seat.

Descrita suficientemente la naturaleza de la invención, así como la manera de realizarse en la práctica, debe hacerse constar que las disposiciones anteriormente indicadas y representadas en los dibujos adjuntos son susceptibles de modificaciones de detalle en cuanto no alteren el principio fundamental.Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.
