DISPOSITIVO DI ILLUMINAZIONE LIGHTING DEVICE
DESCRIZIONE DESCRIPTION
Il presente trovato riguarda un dispositivo di illuminazione. The present invention relates to a lighting device.
Attualmente, sono molto impiegati dei dispositivi di illuminazione che utilizzano, come sorgente luminosa, dei LED. Currently, lighting devices that use LEDs as a light source are widely used.
In genere, tali LED risultano alloggiati all'interno di un corpo di supporto che definisce una superficie parabolica di riflessione e di direzionamento della luce emessa dalla sorgente luminosa. Generally, these LEDs are housed inside a support body which defines a parabolic surface for reflection and direction of the light emitted by the light source.
Tali superficie di riflessione presentano, come detto, una conformazione sostanzialmente cilindrica a parabola e, in qualche caso, sono abbinati a lenti lineari. Said reflection surfaces have, as mentioned, a substantially cylindrical parabola shape and, in some cases, are combined with linear lenses.
Compito precipuo del presente trovato è quello di di mettere a disposizione un nuovo dispositivo di illuminazione. The aim of the present invention is to provide a new lighting device.
All'interno di questo compito, uno scopo importante del presente trovato è quello di mettere a disposizione un dispositivo di illuminazione il quale presenti un elevata praticità di montaggio. Within this aim, an important object of the present invention is to provide a lighting device which is highly practical in assembly.
Un ulteriore scopo del trovato è quello di fornire un dispositivo di illuminazione che presenti un costo di produzione competitivo, in modo tale che il suo impiego risulti vantaggioso anche dal punto di vista economico. A further object of the invention is to provide a lighting device which has a competitive production cost, so that its use is also advantageous from an economic point of view.
Non ultimo scopo del presente trovato è quello di mettere a punto un dispositivo di illuminazione di strutturazione molto semplice e di elevata durata. Not least object of the present invention is to provide a lighting device with a very simple structure and a long life.
Questo compito, nonché questi e altri scopi ancora che meglio appariranno in seguito, vengono raggiunti da un dispositivo di illuminazione caratterizzato dal fatto di comprendere un corpo allungato supportante almeno una sorgente luminosa del tipo a LED e definente almeno una superficie riflettente per la luce emessa da detta almeno una sorgente luminosa del tipo a LED, detta superficie riflettente presentando una concavità rivolta verso detta almeno una sorgente luminosa, essendo inoltre previsti mezzi di dissipazione del calore disposti su detto corpo di supporto dalla parte opposta rispetto a detta superficie riflettente. This aim, as well as these and other objects which will become clearer hereinafter, are achieved by a lighting device characterized in that it comprises an elongated body supporting at least one light source of the LED type and defining at least one reflecting surface for the light emitted by said at least one light source of the LED type, said reflecting surface having a concavity facing said at least one light source, heat dissipation means being also provided arranged on said support body on the opposite side with respect to said reflecting surface.
Ulteriori caratteristiche e vantaggi del trovato risulteranno maggiormente dalla descrizione di alcune forme preferite ma non esclusive di un dispositivo di illuminazione secondo il trovato, illustrate a titolo indicativo e non limitativo negli uniti disegni in cui: Further characteristics and advantages of the invention will become clearer from the description of some preferred but not exclusive forms of a lighting device according to the invention, illustrated by way of non-limiting example in the accompanying drawings in which:
la Figura 1 illustra una vista prospettica e in esploso di un faretto utilizzante un dispositivo di illuminazione secondo il trovato; Figure 1 shows an exploded perspective view of a spotlight using a lighting device according to the invention;
la Figura 2 è una vista il prospettiva del corpo allungato illustrato in Figura 1; Figure 2 is a perspective view of the elongated body illustrated in Figure 1;
la Figura 3 mostra una vista in alzato laterale del corpo allungato; la Figura 4 rappresenta, sempre in alzato laterale, una variante del corpo allungato. Figure 3 shows a side elevation view of the elongated body; Figure 4 is a side elevation view of a variant of the elongated body.
Negli esempi di realizzazione che seguono, singole caratteristiche, riportate in relazione a specifici esempi, potranno in realtà essere intercambiate con altre diverse caratteristiche, esistenti in altri esempi di realizzazione. In the following embodiments, single characteristics, reported in relation to specific examples, can actually be interchanged with other different characteristics, existing in other embodiments.
Inoltre, è da notare che tutto quello che nel corso della procedura di ottenimento del brevetto si rivelasse essere già noto, si intende non essere rivendicato ed oggetto di stralcio (disclaimer) dalle rivendicazioni. Furthermore, it should be noted that everything that in the course of the procedure for obtaining the patent turns out to be already known, is intended not to be claimed and subject to an excerpt (disclaimer) from the claims.
Con riferimento alle sopracitate Figure, un dispositivo di illuminazione, indicato globalmente con il numero di riferimento 1, comprende un corpo allungato 2 il quale supporta almeno una sorgente luminosa 3. With reference to the aforementioned Figures, a lighting device, globally indicated with the reference number 1, comprises an elongated body 2 which supports at least one light source 3.
Il corpo allungato 2, in particolare, definisce almeno una superficie riflettente 4 per la luce emessa dalla sorgente luminosa 3: tale superficie riflettente 4 presenta una concavità rivolta verso la sorgente luminosa 3. The elongated body 2, in particular, defines at least one reflecting surface 4 for the light emitted by the light source 3: this reflecting surface 4 has a concavity facing the light source 3.
Sono inoltre previsti mezzi di dissipazione 5 del calore prodotto dalla sorgente luminosa 3, i quali sono disposti sul corpo di supporto 2 dalla parte opposta rispetto alla superficie riflettente 4. Also provided are means 5 for dissipating the heat produced by the light source 3, which are arranged on the support body 2 on the opposite side with respect to the reflecting surface 4.
Come illustrato, è particolarmente opportuno prevedere che i mezzi di dissipazione 5 siano realizzati in un corpo unico con la superficie riflettente 4. As illustrated, it is particularly appropriate to provide that the dissipation means 5 are made in a single body with the reflecting surface 4.
Secondo una preferita forma di realizzazione, la sorgente luminosa 3 comprende una pluralità di LED reciprocamente distanziati lungo la direzione di sviluppo longitudinale del corpo allungato 2 e supportati da un circuito stampato 3a. According to a preferred embodiment, the light source 3 comprises a plurality of LEDs mutually spaced along the longitudinal development direction of the elongated body 2 and supported by a printed circuit 3a.
Vantaggiosamente, il corpo allungato 2 presenta una sezione trasversale costante e, per tale motivo, si è riscontrato particolarmente opportuno ricavare tale corpo allungato mediante il processo di estrusione di un profilato . Advantageously, the elongated body 2 has a constant cross-section and, for this reason, it has been found particularly appropriate to obtain such an elongated body by means of the process of extruding a section.
Facendo particolare riferimento a quanto illustrato in Figura 2, la superficie riflettente 4 presenta un piano di simmetria passante per la sorgente luminosa 3. With particular reference to what is illustrated in Figure 2, the reflecting surface 4 has a plane of symmetry passing through the light source 3.
Nulla vieta, tuttavia, (come illustrato in Figura 3) che la superficie riflettente 4 sia costituita da due porzioni riflettenti 4a e 4b disposte in maniera asimmetrica rispetto ad un piano passante per la una sorgente luminosa 3. However, nothing prevents (as illustrated in Figure 3) that the reflecting surface 4 is constituted by two reflecting portions 4a and 4b arranged asymmetrically with respect to a plane passing through a light source 3.
Opportunamente i mezzi di dissipazione del calore 5 comprendono una pluralità di alettature 6 sviluppantesi parallelamente alla direzione di sviluppo longitudinale del corpo allungato 2. Conveniently, the heat dissipation means 5 comprise a plurality of fins 6 developing parallel to the longitudinal development direction of the elongated body 2.
Il corpo allungato 2 definisce, inoltre, un ricettacolo di accoglimento 2a a sviluppo longitudinale per la una sorgente luminosa 3. The elongated body 2 also defines a longitudinally extending receiving receptacle 2a for a light source 3.
Nel caso la sorgente luminosa 3 sia costituita da una scheda appiattita 3a supportante una pluralità di LEO reciprocamente distanziati, è opportuno che tale ricettacolo di accoglimento 2a sia costituito da una feritoia allungata entro cui è inseribile a slitta la scheda appiattita 3a. If the light source 3 is constituted by a flattened card 3a supporting a plurality of mutually spaced LEOs, it is advisable that this receiving receptacle 2a consists of an elongated slot within which the flattened card 3a can be slide-inserted.
Secondo un pratico esempio di utilizzazione del trovato, come illustrato in Figura 1, è possibile prevedere che alle estremità del corpo allungato 2 siano fissati dei corpi di chiusura 7 mediante delle viti di fissaggio 30. According to a practical example of use of the invention, as illustrated in Figure 1, it is possible to provide that closing bodies 7 are fixed to the ends of the elongated body 2 by means of fixing screws 30.
Naturalmente, è possibile prevedere altre modalità di fissaggio della sorgente luminosa 3, ad esempio mediante l'utilizzo di viti accoppiabili a fori realizzati mediante macchina utensile. Naturally, it is possible to provide other ways of fixing the light source 3, for example by using screws which can be coupled to holes made by means of a machine tool.
Tali corpi di chiusura hanno anche il compito di trattenere, inferiormente, il pannello di chiusura 8. These closing bodies also have the task of retaining the closing panel 8 at the bottom.
Quindi, il blocco costituito dal corpo allungato 2 e dai corpi di chiusura 7 può essere associato ad un telaio di supporto 20 fornito di una feritoia di alloggiamento 21. Therefore, the block consisting of the elongated body 2 and the closure bodies 7 can be associated with a support frame 20 provided with a housing slot 21.
Dalla feritoia di alloggiamento 21 si ergono, in particolare, delle alette di bloccaggio 24 le quali cooperano con mezzi di bloccaggio a molla 22 resi solidali con i corpi di chiusura 7 mediante l'utilizzo di viti 30. In particular, locking tabs 24 rise from the housing slot 21 and cooperate with spring locking means 22 made integral with the closure bodies 7 by using screws 30.
Tali mezzi di bloccaggio a molla 22 presentano delle porzioni elasticamente cedevoli 23 destinate ad essere trattenute, a scatto, dai bordi superiori delle rispettive alette di bloccaggio 24. These spring locking means 22 have elastically yielding portions 23 intended to be snap-retained by the upper edges of the respective locking tabs 24.
Si è in pratica constatato come in tutte le forme realizzative il trovato abbia raggiunto il compito e gli scopi ad esso preposti. In practice it has been found that in all embodiments the invention has achieved the intended aim and objects.
In pratica i materiali impiegati nonché le dimensioni e lé' forme contingenti potranno essere qualsiasi, a seconda delle esigenze. In practice, the materials used, as well as the contingent shapes and dimensions, may be any according to requirements.
Inoltre tutti i dettagli sono sostituibili da altri elementi tecnicamente equivalenti. Furthermore, all the details can be replaced by other technically equivalent elements.
