Summary of the invention:

The purpose of this utility model is to provide a kind of packaged convenience at the deficiencies in the prior art, utilize the luminous and rotatable magnetic field of the illuminating part revolving light of magnetic field induction.

For achieving the above object, the utility model adopts following technical scheme: it includes lamp body, lamp socket, is fixed with illuminating part, wiring board and induction coil in the lamp body, and illuminating part and induction coil are connected respectively to wiring board; Be fixed with coil in the lamp socket, the coil in the lamp socket is connected to AC/DC changeover switch, and AC/DC changeover switch is connected with battery.

Be fixed with motor in the described lamp socket, the output shaft of motor is connected to rotating disc by the worm and gear power train, and motor is connected with battery.

Be fixed with magnet on described lamp body and the rotating disc respectively.

The utility model utilizes electromagnetic induction principle to provide electric power for illuminating part, need not electric wire between lamp body and the power supply and is connected, and lamp body can be lifted down from lamp socket, and is easier when making packing, and lamp body can also have certain interest with the rotation of the rotating disk in the lamp socket.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a stereogram of the present utility model;

Fig. 2 is a cutaway view of the present utility model;

Fig. 3 is a structural representation of the present utility model;

Fig. 4 is the structural representation of lamp body of the present utility model.

The specific embodiment:

See accompanying drawing 1-4, the utility model comprises: it includeslamp body 10,lamp socket 20, andlamp body 10 of the present utility model is conical, and adopts light transmissive material to make, andlamp socket 20 is a truncated cone-shaped, andlamp body 10 places on the table top oflamp socket 20.

Be fixed withilluminating part 12,wiring board 14 andinduction coil 16 in thelamp body 10, the utilitymodel illuminating part 12 adopts the lower LED of energy consumption, and illuminatingpart 12 andinduction coil 16 are connected respectively towiring board 14;Wiring board 14 can be fixed on thecoil holder 18, and illuminatingpart 12 andinduction coil 16 lay respectively at the both sides ofcoil holder 18.

Be fixed withcoil 162 in thelamp socket 20, thecoil 162 in thelamp socket 20 is connected withpower supply.Coil 162 is alonglamp socket 20 coilings.General,lamp body 10 is less, places threelamp bodies 10 on thelamp socket 20, so theinduction coil 16 in the lamp body is littler than the coil in thelamp socket 162.

Be fixed with motor 22 in thelamp socket 20, the output shaft of motor 22 is connected to rotating disc 24 by the worm and gear power train, and motor 22 is connected with power supply.

Be fixed withmagnet 30 respectively onlamp body 10 and the rotating disc 24,,lamp body 10 be consistent when rotating with rotating disc 24 by attracting each other of themagnet 30 onlamp body 10 and the rotating disc 24.

Power supply of the present utility model adopts direct current, promptly is fixed withbattery 26 in thelamp socket 20, and motor 22 is connected withbattery 26.

For the electric current thatcoil 162 can be changed,coil 162 in thelamp socket 20 is also connected to AC/DC changeover switch 28, make the direct current ofbattery 26 outputs be converted into alternating current, on thecoil 162 because the continuous conversion of AC current direction, makelamp body 10interior induction coils 16 sense the magnetic field of variation, the electric current that changes ininduction coil 16 is input towiring board 14 therefrom, be illuminatingpart 12 power supplies again, makeilluminating part 12 luminous.AC/DC changeover switch 28 is connected withbattery 26.

For making the utility model more attractive in appearance, can addmirror 40 outside thelamp socket 20,lamp body 10 is positioned on themirror 40.

Start power switch, motor 22 driven rotary dishes 24 rotate, and themagnet 30 that themagnet 30 on the rotating disc 24 attracts in thelamp body 10 makeslamp body 10 inmirror 40 surface rotations; Simultaneously,battery 26 is AC/DC changeover switch 28 power supplies, be converted into alternating current by the direct current behind the AC/DC changeover switch 28, alternating current is input tocoil 162, because the electromagnetic induction effect,coil 162 in, form the magnetic field of a variation, the magnetic field of this variation acts on again on theinterior induction coil 16 oflamp body 10, form an electric current that changes oninduction coil 16, these electric current vialine plate 14 backs makeilluminating part 12 luminous forilluminating part 12 power supplies.

Do not have circuit to be connected betweenlamp body 10 of the present utility model and thelamp socket 20, in the time of packing,lamp body 10 can be taken off, and is very convenient;Lamp body 10 is also rotatable, and more common ornament lamp is more attractive in appearance.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
