The problem of solar street light anti-theft cannot be ignored. Solar street lights are generally composed of solar panels, lamp heads and light sources, lamp poles, batteries and controllers. Most of these accessories are connected by hardware components, so they are easy to be dismantled. Since solar panels, lamp heads and light sources and batteries are highly versatile and valuable, they are easy to be stolen. In addition, some solar street lights are installed in rural areas, located in remote sections of the road, and are unattended, so they will inevitably become the target of some lawless elements. Among them, solar panels and batteries are easily stolen, and in some places, only one lamp pole is left. Therefore, the anti-theft problem of solar street lights must be taken seriously.
