The switching element 3 can be, but not limited to, a ring structure. The ring structure 3 includes an internal rotating ring 31 and an external rotating ring 34. The outer peripheries of the internal rotating ring 31 are provided with plural protrusions and the inner peripheries of the external rotating ring 34 are provided with plural recesses corresponding to the protrusions. The external rotating ring 34 is connected with the internal rotating ring 31 by the engagement of the protrusions and the recesses. Besides, the ring structure 3 is further provided with a hole 32 for placing a magnet piece 33 (such as, but not limited to, a magnet). Moreover, the ring 3 is provided with a plurality of functional symbols (not shown in the figures).
The main body 1 can be, but not limited to, a round tube. At least an elastic positioning element 6 (such as, but not limited to, an elastic rod) is provided between the main body 1 and the recesses of the external rotating ring 34 for forming plural positioning points when the ring structure 3 is turned. Furthermore, the round tube 1 is provided with an indicative symbol (not shown in the figures). The ring structure 3 is provided on the round tube 1 of the lighting device and is switched by turning the ring structure 3 on the main body 1.
The circuit board 4 can be, but not limited to, a printed circuit board and is disposed in the main body 1. The magnetic induction element 41 is disposed on the circuit board 4 and the lighting element 2 (such as, but not limited to, a light-emitting diode used in a backlight module) is disposed on the circuit board 4. When the ring structure 3 is to be turned and switched on the round tube 1, plural magnetic fields are produced as a result of the relative change of the positions of the magnet 33 and the magnetic induction element 41 to make the lighting element 2 produce plural induction effects under the control of the magnetic induction element 41 via the circuit board 4. In the meanwhile, users can determine a desired induction effect by referring the indicative symbol (not shown in the figures) of the round tube 1 to indicate a certain functional symbol (not shown in the figures) of the ring structure 3.
Moreover, the lighting device with a magnetic switch further includes a covering 11 and a lens 5. The covering 11 is disposed on the round tube 1 and is provided with a hole 12 (such as, but not limited to, a light-emitting hole) and the lens 5 is disposed on the covering 11 and covers the light-emitting hole 12. Besides, the round tube 1 and the ring structure 3 can be made by waterproof material such as, but not limited to, plastic or metal. Therefore, the lighting device is waterproof after it is assembled.
Accordingly, as disclosed in the above description and attached drawings, the present invention can provide a lighting device with a magnetic switch, wherein plural magnetic fields are produced by using the magnetic piece and the magnetic induction element together to form circuits equivalent to the functional keys and make the lighting element produce plural induction effects under the control of the magnetic induction element via the circuit board. It is new, easy to be operated, and can be put into industrial use and meet the need of the market.
Although the embodiments of the present invention have been described in detail, many modifications and variations may be made by those skilled in the art from the teachings disclosed hereinabove. Therefore, it should be understood that any modification and variation equivalent to the spirit of the present invention be regarded to fall into the scope defined by the appended claims.
