[0014] The present invention provides a solar street light having the following beneficial effects: (1) The solar street light is moved upward by manually pulling the slider. The slider moves upward to break away from the contact with the protective groove and releases the limit on the L-shaped rod. The efficiency of the solar street light directly depends on the angle setting of the solar panel. By setting the slider, the angle of the solar panel can be ensured to be stable at the optimal position, thereby improving the energy collection efficiency and avoiding accidental adjustment, thereby improving the utilization efficiency of photovoltaic energy. After the limit of the lamp pole is released, the lamp pole is manually rotated. The rotation of the lamp pole drives the placement frame to rotate, and the rotation of the placement frame drives the lamp body to rotate. The rotation of the lamp body drives the solar panel to rotate for angle adjustment. The height and angle of the sun will change in different seasons. By adjusting the irradiation angle of the solar panel, it can be ensured that the solar street light can receive solar energy to the maximum extent in different seasons, thereby improving the energy collection efficiency of the solar panel and ensuring the stable operation of the lamp body.

[0015] (2) In the solar street light, the U-shaped plate moves out of contact with the L-shaped plate and releases the limit on the L-shaped plate. After the limit of the L-shaped plate is released, the support rod moves upward under the elastic force of the support spring. The upward movement of the support rod drives the support ring to move upward. The upward movement of the support ring provides additional support force for the lamp pole. After the support ring moves upward, the stability and safety of the lamp pole during rotation can be increased. The additional support force can reduce the risk of the lamp pole tipping over or becoming unstable, thereby ensuring the safety of the staff. When the lamp pole is rotated and adjusted, if there is not enough support force, the bottom and joints of the lamp pole will be subjected to excessive stress, thereby causing deformation of the lamp pole structure. By moving the support ring upward, the stress concentration in the bottom area of ​​the lamp pole can be reduced, thereby extending the service life of the solar street light.

[0016] (3) In this solar street light, the linkage plate is squeezed upward by the liquid inside the detection frame, and the upward movement of the linkage plate drives the linkage rod to move upward. The linkage rod moves upward and contacts the stabilizing groove to limit the button, so that the button cannot be pressed to power on the lamp body before the angle adjustment of the solar panel is completed. In the solar street light system, it is necessary to ensure that all components are in a safe working state before powering on. If the angle adjustment is not completed, the lamp pole or solar panel will become unstable, increasing the risk of injury to the operator during the adjustment process. Waiting for the solar panel angle adjustment to be completed before powering on can avoid the risks of lamp body short circuit or electrical damage, thereby extending the service life of the solar light.
