DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0059] With reference to FIGS. 1-5, there is illustrated a multifunction LED lighting device 1 according to a first embodiment of the invention.

[0060] Said LED lighting device 1 comprises: [0061] a lighting body 2 comprising internally an LED assembly 3; [0062] a frame 4 for supporting said lighting body 2 and for connecting it to a vertical wall; [0063] electrical connection means and mechanical connection means between said frame 4 and said lighting body 2; [0064] an electronic circuit board 5 for converting to low voltage and supplying power to said LED assembly 3.

[0065] Said lighting body 2 is substantially L-shaped and comprises an upright 6 and a projecting arm 7.

[0066] With particular reference to the details of the exploded views in FIGS. 4 and 5, said upright 6 comprises said electrical connection means and said mechanical connection means to said frame, while said arm 7 contains internally said LED assembly 3.

[0067] Said LED assembly 3 is retained between a supporting plate 21 and a lens 22.

[0068] Said electrical connection means and said mechanical connection means are produced by a single connector 8, 9 of male/female type with reversible coupling, which therefore allows easy removal and repositioning of the lighting body 2 from and on the frame 4 during assembly and wall mounting of the device 1.

[0069] In fact, said frame 4 comprises a plate 11 for fixing to the vertical wall, by means of screws 23 and wall plugs 24, and a substantially parallelepiped shaped hollow base 12.

[0070] Said base 12 can be fixed with interlock on said plate 11.

[0071] Said electronic circuit board 5 is housed in said plate 11 for fixing to the wall, while said base 12 is adapted to house the female component 9 of said connector. The corresponding male component 8 of the connector itself is housed at one end of the upright 6 of the lighting body 2.

[0072] A low voltage current transformer is associated with said electronic circuit board 5.

[0073] Said LED lighting device 1 comprises a buffer battery 10 adapted to maintain said device active even without a power supply.

[0074] Said buffer battery 10 is housed in said lighting body 2, inside the upright 6. In this way it is possible to disconnect said lighting body 2 from the frame 4 and use it as a torch and emergency light.

[0075] Said upright 6, id of suitable length, can be used as handle of the lighting body 2 when used as torch.

[0076] Said base 12 comprises, in its lower face, a connector 20 of USB type for supplying power to external electronic devices.

[0077] With reference to FIG. 15, said base 12 comprises accessory electronic apparatus 29 selected from a microphone, a display, a video camera, adapted to interface with a user in Bluetooth or Wi-Fi mode and with a home automatic system to fulfil various functions, and make the multifunction LED lighting device 1 even more complete and high performing.

[0078] FIG. 6 illustrates a multifunction LED lighting device 1 substantially identical to the one described above, except for the fact that it comprises two lighting bodies 2, each provided with its own electrical and mechanical connection means, where said lighting bodies 2 can be alternatively or simultaneously inserted into the frame 4.

[0079] FIGS. 13 and 14 illustrate a section of the multifunction LED lighting device 1 according to a variant of the invention, where the electrical connection means between said frame 4 and said lighting body 2 are of the electromagnetic induction charging type.

[0080] The direct physical contact between said frame 4, in particular the base 12 that houses the female component 9 of said connector, and said lighting body 2, in particular the end of the upright 6 that houses the male component 8 of said connector, allows activation of the passage of current through magnetic induction inside the buffer battery 10 which will then supply said LED assembly 3 with power.

[0081] Due to transfer by means of magnetic induction, it is possible to charge the buffer battery 10 of the lighting body 2, through specific transmitter sensors 31 positioned on the base 12 in the female component 9 of the connector and specific receiver sensors 32 residing on the lighting body in the male component 8 of the connector.

[0082] Said buffer battery 10 in this case performs an important role in the operation of the LED lighting device 1: it does not only come into play only in the case of a power outage or in the case in which the lighting appliance 1 is used as a torch, but is always required for the operation of the LED assembly 3, as there are no physical electrical connections between the base 12 and the lighting body 2.

[0083] To optimize consumption, said LED lighting device 1 comprises a position sensor 28 adapted to detect the physical presence or absence of a moving subject close to the lighting device 1 and to selectively control the transfer of current from said buffer battery 10 to said LED assembly 3 and hence switching on, or not, of the lighting body 2.

[0084] Moreover, said LED lighting device 1 comprises a switch 30 of ON/OFF type, also adapted to act on the passage of current from the buffer battery 10 to the LED assembly 3.

[0085] The electrical connection means of electromagnetic induction type give the maximum level of safety to the multifunction LED lighting device 1, which in this way has no open physical electrical contacts.

[0086] With reference to FIGS. 7-12, there is illustrated a multifunction LED lighting device 1 according to a further and original embodiment, in particular suitable to be ceiling mounted and to operate as a ceiling light.

[0087] Said base 12 has a hexagonal parallelepiped shape and said lighting device 1 comprises six lighting bodies 2 arranged radially on said base 12. It is clear that the number of the lighting bodies 2 can vary, and also in this case, the electric and mechanical connection means of reversible type 8, 9 allow a variable composition of the lighting device 1, as the number and position of the lighting bodies 2 can be selected.

[0088] Said frame 4 comprises a stem 13, arranged between said plate 11 for fixing to the ceiling and said base 12, where said stem 13 comprises, at a first end, bayonet type mechanical connection means 14 with said base 12 and, at a second end, screw type mechanical connection means 15 with said plate 11.

[0089] Said plate 11 also has a hexagonal parallelepiped shape and comprises a box-like body 25 and a closing wall 26.

[0090] Said stem 13 is hollow and is adapted to be passed through by electrical cables 16 terminating with a quick coupling connector 17 adapted to coact with a corresponding connector 18 associated with said base 12.

[0091] In said variant, said electronic circuit board 5 is housed in said base 12.

[0092] The lower face of said base 12, which in use faces the room to be illuminated, comprises a lens 27 and said base 12 also comprises an LED assembly 19 adapted to emit light through said lens 27.

[0093] Inside said base 12 there is also housed a buffer battery 10 connected to said additional LED assembly 19 and to said electronic circuit board 5: in this variant it is the frame 4 itself that operates as a fixed emergency light as the lighting bodies 2 cannot be easily picked up to be used as a torch due to the fact that the lighting device 1 is positioned on the ceiling.

[0094] As is apparent to those skilled in the art, the invention can be produced in numerous variants of forms and dimensions, always achieving the advantages set forth above.
