Description

Descrizione del Brevetto per Invenzione Industriale avente per titolo: "DISPOSITIVO DI ILLUMINAZIONE A DIODI" Description of the Patent for Industrial Invention entitled: "DIODE LIGHTING DEVICE"

DESCRIZIONE DESCRIPTION

Il presente trovato ha come oggetto un dispositivo di illuminazione a diodi. The present invention relates to a diode lighting device.

Come ? noto, le lampade a LED, cio? dispositivi di illuminazione basati sull'impiego di diodi ad emissione luminosa, hanno recentemente sostituito pressoch? completamente le lampade ad incandescenza. As ? known, the LED lamps, that is? lighting devices based on the use of light emitting diodes, have recently replaced almost? incandescent lamps completely.

Le attuali lampade a LED sono realizzate in modo da potere sostituire le tradizionali lampade a incandescenza ed ? quindi possibile utilizzare i portalampada esistenti. Current LED lamps are designed to replace traditional incandescent lamps and ? therefore possible to use the existing lamp holders.

Negli ultimi anni ? cresciuta la sensibilit? nei riguardi dell?inquinamento luminoso generato dalla presenza di fonti luminose esterne inutilmente dirette verso l?alto. In the last few years ? increased sensitivity? with regard to light pollution generated by the presence of external light sources pointlessly directed upwards.

I lampioni stradali, i lampioncini da giardino ed in generale tutti i dispositivi per l?illuminazione esterna tendono a diffondere la luce non soltanto laddove ? necessaria ma anche in direzioni inutili. Street lamps, garden lanterns and in general all outdoor lighting devices tend to diffuse light not only where it is? necessary but also in useless directions.

Ci? provoca un danno ambientale ed anche un danno economico, dovuto principalmente allo spreco di energia elettrica impiegata per illuminare inutilmente zone che non andrebbero illuminate, come la volta celeste, le facciate degli edifici privati e le chiome degli alberi al lato delle strade. There? causes environmental damage and also economic damage, mainly due to the waste of electricity used to uselessly illuminate areas that should not be illuminated, such as the sky, the facades of private buildings and the crowns of trees on the side of the roads.

Per ovviare a tale inconveniente sono stati realizzati nuovi lampioni stradali ed altri dispositivi di illuminazione esterna in grado di direzionare il flusso luminoso verso il basso e in generale soltanto dove ? necessario. To overcome this inconvenience, new street lamps and other external lighting devices have been created which are able to direct the luminous flux downwards and in general only where? necessary.

Tuttavia il costo della sostituzione dei sistemi di illuminazione pu? essere gravoso. However the cost of replacing lighting systems can be burdensome.

Ad esempio, il costo della sostituzione dei lampioncini da giardino di un?abitazione privata pu? fare desistere da tale operazione. For example, the cost of replacing garden lanterns in a private home can to desist from this operation.

Una normale lampada a LED, visibile nella figura 1, ? costituita da una base avente un sistema di aggancio, per esempio una filettatura, sulla quale ? disposta una piastra porta LED protetta da una calotta trasparente. A normal LED lamp, visible in figure 1, ? constituted by a base having a hooking system, for example a thread, on which ? arranged a LED holder plate protected by a transparent cap.

I lampioncini da giardino attualmente esistenti presentano generalmente una semplice calotta impermeabile per la protezione della lampadina la quale diffonde la maggior parte del flusso luminoso verso l?alto. Currently existing garden lanterns generally have a simple waterproof cap for the protection of the bulb which diffuses most of the luminous flux upwards.

Sarebbe auspicabile potere adeguare i dispositivi illuminanti esterni attualmente esistenti senza dovere affrontare un grande impegno economico. It would be desirable to be able to adapt the currently existing external lighting devices without having to face a large economic commitment.

Compito del presente trovato ? quello di realizzare un dispositivo di illuminazione a diodi, in particolare una lampada a LED, che superi gli inconvenienti della tecnica nota citata, riducendo drasticamente l?inquinamento luminoso. Task of the present invention ? that of realizing a diode lighting device, in particular a LED lamp, which overcomes the drawbacks of the cited prior art, drastically reducing light pollution.

Nell?ambito di questo compito, uno scopo del trovato ? quello di realizzare una lampada a LED che possa essere utilizzata nei tradizionali portalampada. Within the scope of this task, an aim of the invention is that of making a LED lamp that can be used in traditional lamp holders.

Un altro scopo del trovato ? quello di realizzare una lampada utilizzabile con particolare vantaggio nei comuni lampioncini da giardino. Another purpose of the invention? that of realizing a lamp that can be used with particular advantage in common garden lanterns.

Un ulteriore scopo del presente trovato ? di fornire una struttura che possa essere prodotta utilizzando elementi e materiali di comune reperibilit? in commercio e che inoltre sia competitiva da un punto di vista economico. Another object of the present invention ? to provide a structure that can be produced using commonly available elements and materials? on the market and which is also competitive from an economic point of view.

Il presente dispositivo, per le sue peculiari caratteristiche realizzative, ? in grado di assicurare le pi? ampie garanzie di affidabilit? e di sicurezza nell'uso. This device, due to its particular construction characteristics, is able to ensure the pi? extensive guarantees of reliability? and safety in use.

Questo ed altri scopi, che meglio appariranno evidenziati in seguito, sono raggiunti da un dispositivo di illuminazione a diodi, caratterizzato dal fatto di comprendere una base munita di un attacco e supportante una calotta trasparente all?interno della quale ? disposta una struttura di sostegno comprendente una superficie riflettente; detta struttura di sostegno definendo una zona interna di passaggio atta a permettere il passaggio di conduttori i quali alimentano una piastra porta LED; detta piastra porta LED e detta superficie riflettente di detta struttura di sostegno diffondendo l?energia luminosa sostanzialmente verso il basso e verso i lati di detto dispositivo di illuminazione. This and other aims, which will become clearer hereinafter, are achieved by a diode lighting device, characterized in that it comprises a base provided with an attachment and supporting a transparent cap inside which arranged a support structure comprising a reflecting surface; said support structure defining an internal passage area suitable for allowing the passage of conductors which feed a LED holder plate; said LED holder plate and said reflecting surface of said support structure diffusing the light energy substantially downwards and towards the sides of said lighting device.

Ulteriori caratteristiche e vantaggi dell'oggetto del presente trovato risulteranno maggiormente evidenziati attraverso un esame della descrizione di una forma di realizzazione preferita, ma non esclusiva, del trovato, illustrata a titolo indicativo e non limitativo nei disegni allegati, in cui: Further characteristics and advantages of the object of the present invention will become more evident through an examination of the description of a preferred, but not exclusive, embodiment of the invention, illustrated by way of example and not in limitation in the attached drawings, in which:

la figura 1 ? una vista laterale in sezione di una lampada a diodi di tipo tradizionale; figure 1 ? a sectional side view of a conventional diode lamp;

la figura 2 ? una vista laterale in sezione della lampada a diodi secondo il presente trovato; figure 2 ? a sectional side view of the diode lamp according to the present invention;

la figura 3 ? una vista prospettica, in trasparenza, della lampada a diodi secondo il presente trovato. figure 3 ? a perspective view, in transparency, of the diode lamp according to the present invention.

Con particolare riferimento ai simboli numerici delle figure 2 e 3, il dispositivo di illuminazione a diodi secondo il trovato, indicato globalmente con il numero di riferimento 1, comprende una base munita di un attacco di tipo standard quale, per esempio, un attacco a vite 3. With particular reference to the numerical symbols of figures 2 and 3, the diode lighting device according to the invention, globally indicated with the reference number 1, comprises a base equipped with a standard type attachment such as, for example, a screw attachment 3.

La base supporta una calotta trasparente 2 all?interno della quale ? disposta una struttura di sostegno 4 comprendente una superficie riflettente, per esempio in metallo. The base supports a transparent cap 2 inside which ? a support structure 4 is arranged comprising a reflecting surface, for example made of metal.

La struttura di sostegno 4 definisce una zona interna di passaggio 5 atta a permettere il passaggio di conduttori 6 i quali alimentano una piastra porta LED 7. The support structure 4 defines an internal passage area 5 suitable for allowing the passage of conductors 6 which feed a LED holder plate 7.

La piastra porta LED 7 pu? essere, per esempio, un modulo LED SMD, un tipo di modulo LED che utilizza la tecnologia di montaggio a superficie (SMT) per montare i chip LED sulle schede a circuito stampato (PCB). The LED holder plate 7 can? be, for example, an SMD LED module, a type of LED module that uses surface mount technology (SMT) to mount LED chips onto printed circuit boards (PCBs).

La piastra porta LED 7 pu? anche essere di tipo COB (Chip On Board), chip di LED multipli saldati direttamente su un substrato a formare un modulo unico. The LED holder plate 7 can? also be of the COB (Chip On Board) type, multiple LED chips soldered directly onto a substrate to form a single module.

Il dispositivo di illuminazione a diodi secondo il trovato permette di portare la piastra porta LED nella parte superiore della calotta della lampadina in modo tale che la superficie radiante sia sostanzialmente rivolta verso il basso anzich? verso l?alto, come in una tradizionale lampada a LED. The diode lighting device according to the invention makes it possible to bring the LED holder plate to the upper part of the cap of the bulb in such a way that the radiating surface is substantially facing downwards instead of facing downwards. upwards, as in a traditional LED lamp.

Ci? permette di indirizzare la luce generata dai LED verso il basso, dove ? utile, anzich? verso il cielo, quando la lampada oggetto del presente trovato ? installata in un comune lampioncino da giardino. There? allows you to direct the light generated by the LEDs downwards, where? useful instead of towards the sky, when the lamp object of the present invention? installed in a common garden lantern.

Il dispositivo di illuminazione a diodi oggetto del presente trovato ? vantaggiosamente utilizzabile in svariate situazioni, per esempio per l?illuminazione di interni, laddove si desideri un?illuminazione indiretta, pi? morbida, che non causi abbagliamenti. The diode lighting device object of the present invention ? advantageously usable in various situations, for example for interior lighting, where indirect lighting is desired, more? soft, not causing glare.

Si ? in pratica constatato come il trovato raggiunga il compito e gli scopi prefissati. Yes ? in practice it has been observed that the invention achieves the intended aim and objects.

Si ? infatti realizzata una nuova lampada a LED che pu? essere vantaggiosamente utilizzata anche in un tradizionale portalampada fornendo tutti i vantaggi della nuova tecnologia senza incorrere in gravose spese economiche. Yes ? in fact created a new LED lamp that can? can also be advantageously used in a traditional lamp holder providing all the advantages of the new technology without incurring heavy economic costs.
