The present invention relates to a street lamp, in particular to an anti-theft solar street lamp, comprising a lamp post, a solar cell panel mounted on the lamp post, a lamp holder, and an energy storage device placed on the ground and electrically connected to the solar cell panel and the lamp holder unit, the energy storage unit and the light pole are fixed on the foot cage buried under the ground through fasteners, the energy storage unit includes a box body and a battery placed in the box body, and the box body is integrated and seamless metal cover structure. The energy storage unit of the solar street lamp of the present invention is placed on the ground surface, which is convenient for installation and maintenance; the box body of the energy storage unit for accommodating the battery is integrated with a seamless panel structure, which effectively avoids the defect that the box body is easy to pry open.

The invention relates to a street lamp using a fuel cell as a power supply. The street lamp is characterized in that a solar battery pack and the fuel cell are used as street lamp power supplies. As shown in the figure, the street lamp is composed of a fuel cell, a solar cell panel, a storage battery, a power supply adaptation and control device, a light source and a system control device. Duringoperation, the electric quantity of the storage battery is maintained by the solar cell and drives the light source. When the electric quantity of the storage battery is insufficient, the fuel cell works to charge the storage battery, and the light source can be directly driven to operate. Through the dynamic control of the work of the fuel cell, the purposes of prolonging the fuel replacement period and improving the fuel utilization rate are achieved. Traditional street lamps are high in maintenance cost and high in failure rate. Weather condition limitation of a pure solar street lamp is achieved, the defects of the solar street lamp are effectively overcome through fuel cell power supply; meanwhile, a fuel cell only generates water and heat, and the damage influence on the environmentis almost zero. By applying the invention, the daily maintenance cost is saved, and energy-saving and environment-friendly social effects can be achieved.
