Patent ID: 8360611

Claim:
A lighting device comprising: a shell; a plurality of luminophors set in an external surface of the shell; a first slideway and a second slideway each of which comprise an up peristome and a down peristome; wherein the up peristome of the first slideway is connected to the up peristome of the second slideway, and the down peristome of the first slideway is connected to the down peristome of the second slideway; a plurality of trigger switches set in the first slideway, each of which is configured for connecting/disconnecting a first circuit which connects one or more of the plurality of luminophors, so as to turn on/off the one or more luminophors; a ball located movable along the slideways; a launching device set in a bottom of the second slideway and configured for driving the ball to move; and a controlling unit configured for connecting/disconnecting a second circuit, so as to connect/disconnect a power supply, which supplies power for the lighting device via the first circuit; wherein, when the controlling unit connects the second circuit and the launching device drives the ball to move from the down peristome of the second slideway to the up peristome of the first slideway, the ball moves along the first slideway to the down peristome of the first slideway due to the gravity, and presses each of the trigger switches in turn, and the pressed trigger switch connects the first circuit, such that, the corresponding one or more luminophors are turned on.
