A twister structure is formed with an upper disc and a lower disc combined together, the upper disc having a recess for an inductive coil to seat therein and the inductive coil is secured by a fixture plate, the inductive coil being connected with a number of feet of lighting devices which have their lighting parts extending out of transparent holes and exposing outwardly from said upper disc to emit light, a magnetic ring being sleeved onto a shaft on the lower disc, a bearing ring with bearings is placed in the upper and the lower discs when the two discs are enclosed. The magnetic ring will be wrapped by the inductive coil, thus when a user steps on the twister and swings his/her body, the upper disc will slide with the rolling of the bearings with respect to the lower disc, and the inductive coil spins with respect to the magnetic ring to generate electric power which is then supplied to lighting devices to activate lighting system.
A twister structure comprising an upper disc, and a lower disc, said upper disc having a recess at an inner center bottom to accommodate an inductive coil therein and said inductive coil being secured by a fixture plate, said inductive coil being connected with a plurality of feet of light devices which have their lighting ends extending through transparent holes and being exposed outwardly from said upper disc, a magnetic ring being sleeved onto a shaft of said lower disc, a bearing ring with bearings being placed in said upper and said lower discs when said two discs are combined, said magnetic ring being wrapped by said inductive coil.
