PURPOSE: An utilization method of a current induction apparatus using inertia is provided to drive an LED(Light Emitting Diode) block by using an induced current generated by the law of inertia. CONSTITUTION: An external frame(1) forms the whole frame. A permanent magnet(6) is provided in the external frame(1). A coil(2) is winded on the central portion of the external frame(1). When the current induction apparatus reciprocates in C and D directions, the permanent magnet(6) goes and comes back both ends of the current induction apparatus via the coil(2) according to an inertia force generated by the law of inertia. A spring(3) and a rubber cushion(4) are adhered to the both end of the current induction apparatus system so that the permanent magnet(6) moves elastically. A ball bearing(5) is adhered to a locus of which the permanent magnet(6) passes in order to reduce the friction force, so that the permanent magnet(6) passes rapidly a space between the coils(2). |
