The present invention relates to a self-powered railroad lamp, characterized in that a swing device powered by suction force and an electricity generation device using potential energy from a torsion spring are additionally provided on a road lamp along a railroad. When a high speed train passes, the swing device harnesses suction force and swings; the swing force causes an electricity generation device using potential energy from a torsion spring to accumulate elastic potential energy; at night, the elastic potential energy can be regulated by a mechanic time setting device and release energy to drive an electricity generator to generate electricity for road lamps for illumination. The benefits are: the suction force generated when a high speed train travels enables the generation of stable and environmentally friendly electricity and the provision of said electricity to railroad roadside lamps for illumination; the disadvantage of electricity instability of wind and solar powered roadside lamps is avoided; the electricity resources of the public grid are also conserved. The elastic potential energy accumulated by a torsion spring is used to store the power generated, thereby replacing batteries for electricity storage, avoiding the environmental pollution caused by chemical batteries, and avoiding the disadvantages of chemical batteries having short service life and requiring constant maintenance. |
