DESCRIZIONE DESCRIPTION
Forma oggetto della presente invenzione un dispositivo di illuminazione a LED di peculiare impatto estetico. Il settore dell'illuminazione da arredamento à ̈ caratterizzato da enormi sforzi di innovazione, sia dal punto di vista estetico che funzionale. Talvolta, le innovazioni funzionali sono dettate dalla necessità di rendere fruibili particolari caratteristiche estetiche, coniugando aspetti di design con necessità di industrializzazione. The subject of the present invention is a LED lighting device with a peculiar aesthetic impact. The furniture lighting sector is characterized by enormous efforts to innovate, both from an aesthetic and functional point of view. Sometimes, functional innovations are dictated by the need to make particular aesthetic characteristics usable, combining design aspects with the need for industrialization.
Negli ultimi anni, hanno conosciuto una notevole diffusione i dispositivi di illuminazione a LED, i quali, tuttavia, hanno imposto la rivisitazione di alcune caratteristiche tecniche, per superare specifiche problematiche di applicazione. In recent years, LED lighting devices have known a considerable diffusion, which, however, have required the revision of some technical characteristics, to overcome specific application problems.
In particolare, le sorgenti luminose a LED sono caratterizzate da un'emissione luminosa molto intensa in prossimità della sorgente stessa; tale emissione à ̈ poco confortevole per l'osservatore, che à ̈ quasi accecato se esposto direttamente alla luce proveniente dalla sorgente. In particular, the LED light sources are characterized by a very intense light emission near the source itself; this emission is not very comfortable for the observer, who is almost blinded if exposed directly to the light coming from the source.
Tale inconveniente ha anche ripercussioni sull'apprezzamento estetico del dispositivo di illuminazione. Infatti, la forte luminosità delle sorgenti rende praticamente impossibile all'osservatore apprezzare l'estetica del dispositivo, che invece à ̈ usualmente studiata per conferire particolare impressione proprio a luce accesa. This drawback also has repercussions on the aesthetic appreciation of the lighting device. In fact, the strong luminosity of the sources makes it practically impossible for the observer to appreciate the aesthetics of the device, which instead is usually designed to give a particular impression when the light is on.
Scopo della presente invenzione à ̈ quello di realizzare un dispositivo di illuminazione a LED di peculiare impatto estetico, che superi gli inconvenienti di cui si à ̈ detto con riferimento all'arte nota. The purpose of the present invention is to provide a LED lighting device with a peculiar aesthetic impact, which overcomes the drawbacks mentioned with reference to the known art.

Il dispositivo 1 comprende inoltre un diffusore 40 in forma di tubetto, realizzato in materiale trasparente alla luce, incolore o colorato, applicabile in maniera rilasciabile alla scatola 20. The device 1 further comprises a diffuser 40 in the form of a tube, made of a material transparent to light, colorless or colored, which can be releasably applied to the box 20.
Ad esempio, il diffusore 40 comprende una parete di diffusione 42, anulare, preferibilmente continua attorno all'asse principale Y, comprendente un piede di innesto 44, di spessore minore, adatto ad essere inserito nella sede 32 definita dalla protuberanza 30. Secondo una forma di realizzazione, l'attacco del tubetto alla scatola avviene per inserimento forzato nella sede; secondo una ulteriore variante, l'attacco avviene tramite un sistema a baionetta; secondo una forma di realizzazione ancora ulteriore, l'attacco avviene tramite sistema filettato. For example, the diffuser 40 comprises an annular diffusion wall 42, preferably continuous around the main axis Y, comprising a lower thickness coupling foot 44, suitable for being inserted into the seat 32 defined by the protuberance 30. According to a shape of realization, the connection of the tube to the box takes place by forced insertion into the seat; according to a further variant, the attachment takes place through a bayonet system; according to a still further embodiment, the attachment takes place by means of a threaded system.
Da parte opposta alla porzione collegata alla scatola, il diffusore 40 Ã ̈ aperto tramite un'apertura di diffusione 50. On the opposite side to the portion connected to the box, the diffuser 40 is opened through a diffusion opening 50.
Secondo varianti di realizzazione, l'apertura di diffusione 50 ha forma quadrata, rettangolare, circolare, ellittica, poligonale spezzata, poligonale mista con tratti rettilinei e curvilinei. According to variant embodiments, the diffusion opening 50 has a square, rectangular, circular, elliptical, split polygonal, mixed polygonal shape with rectilinear and curvilinear portions.
Dato lo spessore del tubetto che definisce il diffusore 40, l'apertura di diffusione 50 Ã ̈ delimitata da un bordo anulare interno e da un bordo anulare esterno che lo circonda. Given the thickness of the tube which defines the diffuser 40, the diffusion opening 50 is delimited by an internal annular edge and an external annular edge which surrounds it.
Secondo varianti di realizzazione, il bordo anulare interno e/o il bordo anulare esterno sono linee chiuse, concentriche o eccentriche fra loro, formate da uno o più tratti curvilinei o rettilinei, di forma identica o differente fra loro.

According to a variant embodiment, the diffuser is partially protruding from the main opening 24 of the box 20.
Secondo una forma di realizzazione della presente invenzione, la protuberanza 30 si estende lungo l'altezza del diffusore 40, circondandolo esternamente, solo per un tratto ridotto, ad esempio sufficiente all'innesto del diffusore (figura 6), preferibilmente per meno della metà dell'altezza totale del diffusore. Secondo una ulteriore forma di realizzazione della presente invenzione, la protuberanza 30 si estende lungo il diffusore 40, circondandolo esternamente, solo parzialmente, oltre la metà dell'altezza totale del diffusore (figura 7). According to an embodiment of the present invention, the protuberance 30 extends along the height of the diffuser 40, surrounding it externally, only for a small portion, for example sufficient for the coupling of the diffuser (Figure 6), preferably for less than half of the total height of the diffuser. According to a further embodiment of the present invention, the protuberance 30 extends along the diffuser 40, surrounding it externally, only partially, beyond half of the total height of the diffuser (Figure 7).
Secondo una forma di realizzazione ancora ulteriore, la protuberanza 30 si estende per tutta l'altezza del diffusore 40, circondandolo esternamente (figura 8), realizzando una sorta di camicia opaca che circonda il diffusore trasparente. According to a still further embodiment, the protuberance 30 extends over the entire height of the diffuser 40, surrounding it externally (Figure 8), creating a sort of opaque jacket that surrounds the transparent diffuser.
In tale variante, il diffusore appare comunque all'esterno in forma di corona 46 trasparente, incolore o colorata, che delimita l'apertura di diffusione 50, a filo con l'apertura della protuberanza 30.

According to an embodiment, the lens 60 is disposed completely externally to the diffuser 40. According to a variant embodiment, the lens 60 is disposed externally to the box 20, ie in the rear region of the bottom 22 of said box (Figure 6). According to a further variant of embodiment, the lens 60 is arranged at least partially in the protuberance 30; preferably, the lens 60 is completely housed in the protuberance 30 (Figures 7 and 8).
Preferibilmente, si definisce una direzione di emissione Z che passa per il bordo della lente 60 all'emissione e per il bordo interno libero del diffusore 40 (figura 6); detta direzione di emissione Z forma con l'asse principale Y un angolo α preferibilmente minore o uguale a 45°. Preferably, an emission direction Z is defined which passes through the edge of the lens 60 upon emission and through the free inner edge of the diffuser 40 (Figure 6); said emission direction Z forms an angle Î ± with the main axis Y, preferably less than or equal to 45 °.
Secondo ulteriori varianti di realizzazione, detta direzione di emissione Z Ã ̈ definita fra il bordo della lente 60 all'emissione e il bordo interno libero della scatola 20 (figura 34). According to further embodiments, said emission direction Z is defined between the edge of the lens 60 at the emission and the free inner edge of the box 20 (Figure 34).
Secondo una forma preferita di realizzazione, la scatola 20 comprende un profilato 70 e una maschera 72, interna al profilato 70, che realizza il fondo 22 e le sporgenze 30, in cui à ̈ alloggiato il diffusore 40 (figure 9, 10 e 11). According to a preferred embodiment, the box 20 comprises a profile 70 and a mask 72, inside the profile 70, which forms the bottom 22 and the protrusions 30, in which the diffuser 40 is housed (figures 9, 10 and 11) .
Il dispositivo 1 comprende inoltre un apparato elettrico 80 e sorgenti luminose a LED ad esso applicate, ad esempio alloggiato fra la base del profilato 70 e il fondo 22 della maschera 72. The device 1 also comprises an electrical apparatus 80 and LED light sources applied thereto, for example housed between the base of the profile 70 and the bottom 22 of the mask 72.
Secondo una ulteriore forma di realizzazione, il dispositivo 1 comprende una piastra di montaggio 90, applicabile alla parete, alla quale il profilato 70 o la scatola 20 sono agganciabili, per il supporto del dispositivo. According to a further embodiment, the device 1 comprises a mounting plate 90, applicable to the wall, to which the section 70 or the box 20 can be hooked, for supporting the device.
Secondo ulteriori varianti di realizzazione, la scatola 20 comprende mezzi di aggancio a molla 100, sporgenti esternamente dalla scatola, per il collegamento a scatto in una predefinita sede incassata nella parete. According to further embodiments, the box 20 comprises spring hooking means 100, protruding externally from the box, for snap connection in a predefined seat embedded in the wall.
Innovativamente, il dispositivo di illuminazione secondo la presente invenzione consente di utilizzare sorgenti luminose a LED evitando che l'emissione luminosa disturbi l'osservatore. Innovatively, the lighting device according to the present invention allows to use LED light sources avoiding that the light emission disturbs the observer.
Vantaggiosamente, inoltre, il dispositivo consente di ottenere un pregevole effetto estetico, in quanto il diffusore trasparente, incolore o colorato, a luce accesa, realizza un tubo di diffusione della luce che emerge all'esterno attraverso la corona del diffusore stesso. Advantageously, moreover, the device allows to obtain a valuable aesthetic effect, since the transparent, colorless or colored diffuser, when the light is on, creates a light diffusion tube that emerges outside through the crown of the diffuser itself.
