DETAILED DESCRIPTION
Referring to FIGS. 1-5, a lighting device 1 is disclosed. The lighting device 1 includes a hollow shell 10, a first slideway 20, a second slideway 30, a launching device 70, a controlling unit 80, a ball 40, and a plurality of luminophors 50. The luminophors 50 are set in an external surface of the shell 10.
In the exemplary embodiment, the first slideway 20 includes a plurality of trigger switches 21. Each of the trigger switches 21 is configured for connecting/disconnecting a first circuit 7, so as to turn on/off one or more luminophors 50. The controlling unit 80 is configured for connecting/disconnecting a second circuit 8, so as to connect/disconnect a power supply, which supplies power for the lighting device 1 via the second circuit 8. In the exemplary embodiment, the controlling unit 80 may be a switch. User can press the switch 80 to connect/disconnect the second circuit 8. In another embodiment, the controlling unit 80 may be a timer, and the second circuit 8 is disconnected when the time elapsed reaches a predetermined time. The launching device 70 is set in the bottom of the second slideway 30, and is configured for driving the ball 40 to move.
When the second circuit 8 is connected by the controlling unit 80, the launching device 70 drives the ball 40 to move from the second slideway 30 to the first slideway 20, and then the ball 40 moves along the first slideway 20 to an original position, where the ball 40 is originally placed, due to the gravity. During the movement of the ball 40 along the first slideway 20, the ball 40 presses each of the trigger switches 21 in turn. The pressed trigger switch 21 connects the first circuit 7, thus, one or more luminophors 50 connected to the first circuit 7 are turned on. For better understanding the disclosure, the following is a detailed exemplary embodiment.
The first slideway 20 is spiral shaped, and includes an up peristome 22 and a down peristome 23.
The second slideway 30 is a pipe, and includes an up peristome 32 and a down peristome 33. The up peristome 32 is connected to the up peristome 22 of the first slideway 20, and the down peristome 33 is connected to the down peristome 23 of the first slideway 20.
Each of the trigger switches 21, positioned at a predetermined position of the first slideway 20, includes an induction coil 210 fixed in the first slideway 20, a spring 211, and a sheet metal 212. One end of the spring 211 is connected to the induction coil 210, and another end of the spring 211 is connected to the sheet metal 212. The sheet metal 212 is located on the induction coil 210 via the spring 211.
The launching device 70 includes a controlling switch 24 and an elastic element 60. The elastic element 60 is connected to the bottom of the second slideway 30. The controlling switch 24 is connected to the elastic element 60, and a portion of the controlling switch 24 is exposed out of the second slideway 30 via a sliding groove (not labeled) of the second slideway 30. The ball 40 is located on the controlling switch 24. In the exemplary embodiment, the ball 40 is a metal ball.
When the second circuit 8 is connected by the controlling unit 80, and the controlling switch 24 is pressed along the sliding groove, the controlling switch 24 drives the elastic element 60 to move along the sliding groove, and the elastic element 60 is deformed. In the exemplary embodiment, the elastic element 60 is a spring. When releasing the press operation on the controlling switch 24, the elastic element 60 resumes, and drives the ball 40 to flip and move from the down peristome 33 of the second slideway 30 to the up peristome 32 of the second slideway 30, leading the ball 40 to the up peristome 22. Then the ball 40 moves from the up peristome 22 of the first slideway 20 to the down peristome 23 of the first slideway 20 due to the gravity. During the movement of the ball 40, the ball 40 presses the sheet metal 212 of each one of the trigger switches 21, and the pressed sheet metal 212 presses the spring 211 to touch the induction coil 210, and thus, the trigger switch 21 is pressed. The pressed trigger switch 21 connects the first circuit 7, and one or more luminophors 50 are turned on.
Simultaneously, when the first circuit 7 is connected, the induction coil 210 generates a magnetic field. The magnetic field adsorbs the sheet metal 212 to continuously touch the induction coil 210, and thus, the first circuit 7 keeps a connection state, and the one or more luminophors 50 keep in a turned-on state.
When the controlling unit 80 disconnects the second circuit 8, so that, all the first circuit 7 are disconnected. The magnetic field disappears, thus, the spring 211 resumes, and drives the sheet metal 212 to leave the induction coil 210. One or more luminophors 50 connected to the trigger switch 21 are turned off.
Although the present disclosure has been specifically described on the basis of the embodiments thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiments without departing from the scope and spirit of the disclosure.
