Electromagnetic induction coils are fixed on the two ends of the cantilever beam. The electromagnetic induction coils are led out of leads to be connected with the LED base. A pair of curved magnets of opposite polarity are installed above and below the electromagnetic induction coils in the hollow cavity of the screwrod. A piezoelectric film is respectively fixed on the upper and lower surfaces of the cantilever beam. The back surface of the piezoelectric film is provided with a layer of electrode which is leadout of the lead to be connected with the LED base. The LED light emitting unit, the magnetoelectric unit and the piezoelectric unit are combined in the screw structure so that the acquired vibration energy can be utilized to be converted into electric energy to light up the LED lamp of the external side of the bolt in case of vibration of the screw.
