Sia la piastra dissipatrice 38, sia la piastra 34 del circuito elettronico 35 sono collegate alla parete 29 di fondo del coperchio interno 27 tramite rispettive pluralità di viti indicate rispettivamente con 40 e 41; in particolare, la sorgente luminosa 36 è montata sul coperchio interno 27 in posizione affacciata ad una feritoia 42 longitudinale ricavata attraverso la parete 29 di fondo e presentante bordi laterali smussati con gli smussi definenti fra loro un angolo di 120°; mentre il circuito elettronico 35 presenta dei connettori 43 per il proprio collegamento da una parte alla batteria 14 e dall'altra ai connettori (non illustrati) del tappo 10, e comprende un interruttore 44 di accensione provvisto di un pulsante di commutazione, il quale è mobile attraverso un foro 45 ricavato attraverso l'appendice 31. Il circuito elettronico 35 è, inoltre, provvisto di un led di controllo 46, che impegna un relativo foro 47 ricavato attraverso la parete 29 di fondo del coperchio interno 27. Both the dissipating plate 38 and the plate 34 of the electronic circuit 35 are connected to the bottom wall 29 of the internal cover 27 by means of respective plurality of screws indicated respectively with 40 and 41; in particular, the light source 36 is mounted on the inner cover 27 in a position facing a longitudinal slot 42 obtained through the bottom wall 29 and having bevelled side edges with the bevels defining an angle of 120 ° to each other; while the electronic circuit 35 has connectors 43 for its connection on one side to the battery 14 and on the other to the connectors (not shown) of the cap 10, and comprises an ignition switch 44 provided with a changeover button, which is movable through a hole 45 obtained through the appendix 31. The electronic circuit 35 is also provided with a control LED 46, which engages a relative hole 47 obtained through the bottom wall 29 of the internal cover 27.

Il coperchio esterno 28 è montato sul corpo a tazza 15 a chiusura dell'apertura 26 ed è provvisto internamente di spine (non illustrate), le quali impegnano rispettive feritoie 48 periferiche ricavate sul coperchio interno 27. Il coperchio esterno 28 è collegato alla parete posteriore 16 del corpo a tazza 15 tramite viti 49 passanti, le quali impegnano rispettive feritoie periferiche 50 ricavate sul coperchio interno 27, e presenta una finestra 51 chiusa da un elemento trasparente 52 atto a rendere visibili dall'esterno sia la feritoia 42, sia il led di controllo 46. Il coperchio esterno 28 presenta, infine, un foro, il quale è coassiale al foro 45 ed è chiuso da una membrana 53 flessibile atta a permettere l'azionamento ST (soft-touch) dall'esterno dell'interruttore 44 di accensione. The external cover 28 is mounted on the cup-shaped body 15 to close the opening 26 and is internally provided with pins (not shown), which engage respective peripheral slots 48 obtained on the internal cover 27. The external cover 28 is connected to the rear wall 16 of the cup-shaped body 15 by means of through screws 49, which engage respective peripheral slots 50 obtained on the internal cover 27, and has a window 51 closed by a transparent element 52 able to make both the slot 42 and the LED visible from the outside The external cover 28 finally has a hole, which is coaxial with the hole 45 and is closed by a flexible membrane 53 suitable for allowing the ST (soft-touch) actuation from the outside of the switch 44 of power on.

Il funzionamento del dispositivo di illuminazione 1 sopra descritto discende direttamente dalla descrizione che precede e non richiede ulteriori spiegazioni. E', tuttavia, importante precisare che l'utilizzo della piastra dissipatrice 38 permette di realizzare, all'interno dell'astuccio 8 un supporto per la sorgente luminosa 36 completamente separato dalla piastra 34 ed in grado di evitare che il circuito elettronico 35 sia esposto, per conduzione diretta, al calore prodotto dalla sorgente luminosa 36 e, allo stesso tempo, di mantenere la piastra 37 di base della sorgente luminosa 36 ad una temperatura sufficientemente bassa da consentire l'ancoraggio per incollaggio della sorgente luminosa 36 al suo supporto, ossia alla piastra dissipatrice 38. The operation of the lighting device 1 described above derives directly from the preceding description and does not require further explanations. However, it is important to specify that the use of the dissipating plate 38 allows to realize, inside the case 8, a support for the light source 36 completely separate from the plate 34 and able to prevent the electronic circuit 35 from being exposed. , by direct conduction, to the heat produced by the light source 36 and, at the same time, to keep the base plate 37 of the light source 36 at a sufficiently low temperature to allow the anchoring by gluing of the light source 36 to its support, i.e. to the heat sink 38.
