Description
La presente invenzione ha per oggetto un dispositivo di illuminazione includente LED del tipo descritto nel preambolo della prima rivendicazione. The present invention relates to a lighting device including LEDs of the type described in the preamble of the first claim.
Sono attualmente noti i LED, sigla derivata dall’acronimo inglese di light emitting diode, recentemente utilizzati per l’illuminazione di ambienti vari, quali ad esempio: ambienti domestici, uffici, ambienti aperti quali piazze e giardini e altro ancora. LEDs are currently known, an acronym derived from the English acronym for light emitting diode, recently used for the lighting of various environments, such as: domestic environments, offices, open environments such as squares and gardens and more.
I LED per illuminazione comportano differenti vantaggi rispetto alle illuminazioni più tradizionali quali, per esempio, le lampade ad incandescenza e le lampade a fluorescenza. LEDs for lighting have different advantages over more traditional lighting such as, for example, incandescent lamps and fluorescent lamps.
In particolare, i LED hanno un volume molto ridotto, anche inferiore al cm<3>, un’efficienza molto elevata, producono una luce che può ottenere una colorazione desiderata, si accendono molto velocemente quando sollecitati da corrente elettrica ed altro ancora. In particular, the LEDs have a very small volume, even less than <3> cm, a very high efficiency, produce a light that can obtain a desired color, light up very quickly when stressed by electric current and more.
Accanto ai detti vantaggi le illuminazioni LED presentano alcuni importanti inconvenienti. Besides the said advantages, the LED illuminations have some important drawbacks.
Infatti, i LED producono un’illuminazione molto puntiforme che non si presta all’illuminazione diffusa di ambienti interni e simili. Ad esempio per la lettura è necessaria un’illuminazione diffusa e non puntiforme. In fact, the LEDs produce very point-like lighting that does not lend itself to the diffused lighting of indoor environments and the like. For example, for reading, diffused and non-point lighting is required.
In questa situazione il compito tecnico della presente invenzione è quello di ideare un dispositivo di illuminazione includente LED in grado di ovviare sostanzialmente agli inconvenienti citati. In this situation, the technical task of the present invention is to devise a lighting device including LEDs capable of substantially obviating the aforementioned drawbacks.
Nell'ambito di detto compito tecnico è un importante scopo dell'invenzione ottenere un dispositivo di illuminazione includente LED che realizzi un’illuminazione diffusa. Within the scope of said technical task, it is an important object of the invention to obtain a lighting device including LEDs that produces diffused lighting.
Il compito tecnico e gli scopi specificati sono raggiunti da un dispositivo di illuminazione includente LED che si caratterizza per il fatto di comprendere una o più delle nuove soluzioni tecniche in seguito descritte e rivendicate. The technical task and the specified aims are achieved by a lighting device including LED which is characterized in that it comprises one or more of the new technical solutions described and claimed hereinafter.
Negli allegati disegni sono illustrate a titolo di esempio esecuzioni preferite dell’invenzione. In particolare: In the attached drawings, preferred embodiments of the invention are illustrated by way of example. In particular:

Esso comprende almeno un LED 2, una struttura di supporto 3 per il LED 2 ed una lente 4, sovrastante il LED 2, sostenuta dalla struttura di supporto 3 e atta a modificare l’illuminazione del LED 2 in particolare per creare un’illuminazione diffusa. It comprises at least one LED 2, a support structure 3 for the LED 2 and a lens 4, above the LED 2, supported by the support structure 3 and adapted to modify the illumination of the LED 2 in particular to create a diffused illumination. .
Nei dettagli la lente 4 è opportunamente in materiale vetroso, e preferibilmente in vetro, ed ha opportunamente una forma sostanzialmente di calotta sferica avente la parte inferiore dalla superficie sostanzialmente piana. In detail, the lens 4 is suitably made of glassy material, and preferably made of glass, and suitably has a substantially spherical shape whose lower part has a substantially flat surface.
Essa ha un diametro di base preferibilmente compreso tra 1 cm e 10 cm e più preferibilmente tra 2 cm e 5 cm, un’altezza compresa tra 0,4 cm e 6 cm, e più preferibilmente tra 1 cm e 3 cm ed un rapporto tra il diametro e l’altezza preferibilmente compreso tra 2 e 3. It has a base diameter preferably between 1 cm and 10 cm and more preferably between 2 cm and 5 cm, a height between 0.4 cm and 6 cm, and more preferably between 1 cm and 3 cm and a ratio of the diameter and height preferably between 2 and 3.
Il LED 2 è costituito da un circuito stampato 2a ed un bulbo 2b. The LED 2 consists of a printed circuit 2a and a bulb 2b.
Il circuito stampato 2a è opportunamente sostanzialmente rettangolare ed ha dimensioni di base comprese tra 1 mm e 5 mm. The printed circuit 2a is suitably substantially rectangular and has basic dimensions between 1 mm and 5 mm.
Il bulbo 2b è in materiale polimerico ed ha preferibilmente un diametro esterno compreso tra 0,3 mm e 3 mm e più preferibilmente compreso tra 1,5 mm e 2 mm. Esso ha inoltre una forma sostanzialmente semisferica. The bulb 2b is made of polymeric material and preferably has an external diameter between 0.3 mm and 3 mm and more preferably between 1.5 mm and 2 mm. It also has a substantially hemispherical shape.
Il LED 2 ha una potenza compresa tra 1 W e 50 W e più preferibilmente tra 1 W e 20 W e più preferibilmente ancora prossima a 20 W. The LED 2 has a power of between 1 W and 50 W and more preferably between 1 W and 20 W and more preferably still close to 20 W.
La struttura di supporto 3 è opportunamente costituita da un’asta metallica a sezione normale all’incirca ellissoidale e comprendente due facce almeno parzialmente piane in prossimità del LED 2. Tale asta metallica ha un diametro medio all’incirca compreso tra 1 mm e 5 mm. The support structure 3 is conveniently constituted by a metal rod with a normal section approximately ellipsoidal and comprising two at least partially flat faces near the LED 2. This metal rod has an average diameter between 1 mm and 5 mm. .
La struttura di supporto 3 comprende inoltre un elemento di sostegno 5, atto a sostenere la lente 4 in modo tale che la stessa sia posta in prossimità del LED 2 ma non a diretto contatto dello stesso, come illustrato in Fig.2. The support structure 3 also comprises a support element 5, adapted to support the lens 4 in such a way that it is placed in proximity to the LED 2 but not in direct contact with it, as illustrated in Fig.2.
