A railroad lamp that generates electricity using a tension spring and suction force, comprising: a suction-force swing device, a tension-spring elastic potential energy generating device, a time-setting device, and a road lamp assembly. The road lamp assembly comprises a light-emitting element (4) and a road lamp post (41). The swing device comprises a suction panel (11) and brackets (12) disposed on the front portion of the post (41), and two chains (13) , two chain wheels (14), a counterweight (15), first gearboxes (16), a non-return ratchet mechanism (5), a spline shaft (18), a header plate (19), a compression spring (182), a conical driving friction wheel (181), a second gearbox (39), and two support plates (17) are disposed on the upper portion of the post (41). The tension-spring elastic potential energy generating device is disposed inside the post (41). The time-setting device controls said energy generating device to generate energy. The light-emitting element (4) is able to emit light at night as a result of the energy generated by said energy generating device. |
