Descrizione di modello di utilità nome: Description of utility model name:

Forma oggetto del presente trovato una lampada secondo il preambolo aella rivendicazione principale The present invention relates to a lamp according to the preamble to the main claim

Sono note da tempo lampade (intendendo con tale termine un qualsiasi manufatto presentante sorgente luminosa provvista di supporto) impiegate per l'illuminazione di un ambiente o per la decorazione di quest'ultimo attraverso l'emissione di luce colorata. Lamps have been known for some time (meaning by this term any product having a light source provided with a support) used for the illumination of an environment or for the decoration of the latter through the emission of colored light.

Scopo del presente trovat o e quella di offrire una lampada che consenta l'emissione di una luce atta a illuminare e contemporaneamente decorare un ambiente in cui la lampada è posta The purpose of this invention is to offer a lamp that allows the emission of a light capable of illuminating and at the same time decorating an environment in which the lamp is placed

Un altro scopo è quello di offrire una lampada del tipo citato che consenta l'emissione di una luce almeno di due differenti colori Another object is to provide a lamp of the aforementioned type which allows the emission of a light of at least two different colors

Un ulteriore scopo è quello di offrire una lampada a basso consumo energetico, che sia semplice da realizzare e che abbia costi relativamente contenuti A further object is to offer a lamp with low energy consumption, which is simple to manufacture and which has relatively low costs

Questi ed altri scopi che risulteranno evidenti all'esperto del ramo vengono raggiunti da una lampada secondo le allegate rivendicazioni. These and other objects which will be evident to the skilled in the art are achieved by a lamp according to the attached claims.

Per una miglior comprensione del presente trovato si allega a titolo puramente indicativo, ma non limitativo, il seguente disegno, m cui For a better understanding of the present invention, the following drawing is attached as a purely indicative but not limitative drawing, in which

la figura 1 mostra una vista m sezione longitudinale di una lampada secondo il trovato, la figura 2 mostra una vista ingrandita della parte indicata con A m figura 1, figure 1 shows a longitudinal sectional view of a lamp according to the invention, figure 2 shows an enlarged view of the part indicated by A m figure 1,

la figura 3 mostra una vista prospettica della parte superiore della lampada di figura 1 con alcune parti omesse ed altre m trasparenza per maggior chiarezza figure 3 shows a perspective view of the upper part of the lamp of figure 1 with some parts omitted and others transparency for greater clarity

Con riferimento alle citate figure, una lampada secondo il trovato è indicata genericamente con 1 e comprende un supporto 2 ed un corpo 3 da cui vi e fuoriuscita di luce II corpo 3 è, nell'esempio, posto all'estremità superiore (con riferimento alla figura 1) del supporto 2, quest'ultimo comprende una base d'appoggio 4. With reference to the aforementioned figures, a lamp according to the invention is generally indicated with 1 and comprises a support 2 and a body 3 from which light comes out. The body 3 is, in the example, located at the upper end (with reference to the figure 1) of the support 2, the latter comprises a support base 4.

Il supporto 2 comprende una cavità interna 8 aperta in prossimità della base 4 ove è previsto un organo di chiusura 9, ad esempio a vite. La cavita 8 è atta a contenere, preferibilmente, una o più pile (non mostrate) atte ad alimentare almeno una sorgente luminosa S presente nel corpo 3 A tale sorgente, l'energia elettrica fornita dalle pile (o altro organo accumulatore di energia) viene trasferita attraverso usuali organi conduttori (non mostrati) inseriti nel supporto 2 e nel corpo 3. Ad esempio, in una cavita 11 sovrastante quella 8 piu sopra citata è previsto almeno un conduttore che attraverso organi di contatto strisciante associati ad una porzione estremale 12 del supporto 2 può entrare in contatto con corrispondenti organi di contatto strisciante associati ad una porzione estremale 14 del corpo 3 accoppiata a quella 12 sopra citata Ciò quando il corpo 3 può essere ruotato sul supporto 2, m tal caso, la cooperazione tra gli organi di contatto sopra citati avviene solo quando tale corpo e ruotato m una particolare posizione sul supporto Ovviamente, l'alimentazione al corpo 3 può essere ottenuta in altro modo m sè noto, ad esempio mediante allacciamento ad una rete elettrica fissa oppure collegando con cavi la o le pile alla sorgente luminosa nel corpo 3. Analogamente, possono essere previsti mezzi interruttori per attivare o meno tale alimentazione alla sorgente. The support 2 comprises an internal cavity 8 open in proximity to the base 4 where a closing member 9 is provided, for example a screw. The cavity 8 is adapted to contain, preferably, one or more batteries (not shown) able to supply at least one light source S present in the body 3. transferred through usual conducting members (not shown) inserted in the support 2 and in the body 3. For example, in a cavity 11 above the aforementioned 8 there is at least one conductor which, through sliding contact members associated with an extremal portion 12 of the support 2 can come into contact with corresponding sliding contact members associated with an extremal portion 14 of the body 3 coupled to that 12 mentioned above. cited occurs only when this body is rotated in a particular position on the support Obviously, the power supply to the body 3 can be obtained in another way m sè n oto, for example by connection to a fixed electrical network or by connecting the battery or batteries to the light source in the body 3 with cables.

La sorgente luminosa S comprende, nella forma di esecuzione delle figure, una pluralità di diodi emettitori di luce o led 15 e 16 associati a corrispondenti facce contrapposte 17 e 18 e di un elemento di supporto piano 19 su cui sono presenti connessioni elettriche stampate (non mostrate). A tale elemento 19 (o circuito stampato), ι led 15 e 16 sono associati (e collegati elettricamente) m modo noto qualsiasi. I led 15 e 16 sono microled in sè noti e possono generare luce monocromatica oppure ι led 15 generano una luce di un colore, mentre ι led 16 generano una luce di un diverso colore. Nel primo caso, è previsto frontalmente ai led 16 un organo 20 filtrante la luce emessa da tale led ed atto a modificarne il colore. Tale organo è di tipo in sè noto e non verrà ulteriormente descritto. The light source S comprises, in the embodiment of the figures, a plurality of light emitting diodes or LEDs 15 and 16 associated with corresponding opposite faces 17 and 18 and a flat support element 19 on which printed electrical connections are present (not shown). With this element 19 (or printed circuit), leds 15 and 16 are associated (and electrically connected) in any known way. The LEDs 15 and 16 are known microleds per se and can generate monochromatic light or the LEDs 15 generate a light of one color, while the LEDs 16 generate a light of a different color. In the first case, an organ 20 is provided in front of the LEDs 16 which filters the light emitted by this LED and is adapted to modify its color. This member is of a per se known type and will not be further described.

L'organo 20 e l'elemento 19 sono posti entro una cavità 22 del corpo 3 e sono vincolati a quest'ultimo m modo in sè noto (ad esempio incollati) In modo altrettanto noto, le connessioni elettriche dell'elemento 19 sono collegate agli organi di contatto elettrico del corpo 3 ad esempio, all'elemento 19 giungono conduttori elettrici (non mostrati) connessi a zone 23 e 24 di tale elemento. The member 20 and the element 19 are placed within a cavity 22 of the body 3 and are connected to the latter in a known way (for example glued). In a similarly known way, the electrical connections of the element 19 are connected to the electrical contact members of the body 3 for example, electrical conductors (not shown) connected to areas 23 and 24 of this element reach the element 19.

La cavita 22 presenta una parete diamantata o prismatica 22A per una miglior diffusione della luce attraverso il corpo 3 Almeno parte di quest'ultimo è almeno in parte trasparente alla luce e supporta un elemento di chiusura 27 (anch'esso almeno parzialmente trasparente alla luce) posto al di sopra della cavità 22 e vincolato al corpo 3, ad esempio mediante avvitamento accoppiamento a baionetta. The cavity 22 has a diamond or prismatic wall 22A for a better diffusion of light through the body 3 At least part of the latter is at least partially transparent to light and supports a closing element 27 (also at least partially transparent to light) placed above the cavity 22 and constrained to the body 3, for example by screwing bayonet coupling.

Grazie alla particolare conformazione della sorgente luminosa S ed alla presenza dell'organo filtrante 20, dal corpo 3 viene emessa luce comprendente una pluralità di raggi luminosi emessi in diverse direzioni spaziali e presentanti colorazioni diverse. Ad esempio, i led 15 emettono luce bianca che fuoriesce superiormente dal corpo 3, mentre la luce emessa dai led 16 è filtrata per divenire luce blu emessa inferiormente e lateralmente da tale corpo. Thanks to the particular conformation of the light source S and the presence of the filtering member 20, light is emitted from the body 3 comprising a plurality of light rays emitted in different spatial directions and having different colors. For example, the LEDs 15 emit white light that comes out of the upper body 3, while the light emitted by the LEDs 16 is filtered to become blue light emitted below and laterally by this body.

Ovviamente, nulla vieta di realizzare la sorgente S con led 15 e 16 di diversi colori al fine di avere lo stesso risultato sopra descritto di un'emissione di luce di diverso colore da parti diverse del corpo 3 Un'altra variante, infine, prevede un unico led 15 e 16 frontalmente al quale è posto l'organo 20 opportunamente realizzato in modo da filtrare e colorare solo una parte della luce emessa dal led. Obviously, there is nothing to prevent the creation of the source S with LEDs 15 and 16 of different colors in order to have the same result described above of an emission of light of a different color from different parts of the body.3 Finally, another variant provides for a single LED 15 and 16 in front of which the organ 20 is suitably made in such a way as to filter and color only a part of the light emitted by the LED.
