According to the street lamp, the lamp cap integrates power generation and energy storage functions, the solar panel is directly used for power generation, and the storage battery is used for energy storage, so that the lighting requirement of the lamp cap is met. And the cooling air that the air-supply line was advanced divides into three routes, passes through first hard tube in the roof of battery case, second hard tube and the arc in the diapire respectively, in time takes away the heat of battery case and the heat of first, two radiating blocks to guarantee high-efficient heat dissipation.

Furthermore, a first cooling fan and a second cooling fan are arranged on the bottom wall of the shell of the storage battery shell, and the first cooling fan and the second cooling fan are symmetrical relative to the plane where the baffle is located; the controller controls the street lamp, when the street lamp is in an opening state, when the absolute value of the difference value of the measured values of the first and second light intensity sensors is greater than a set threshold value, and the measured value of the first light intensity sensor is greater than that of the second light intensity sensor, the first cooling fan is opened, and the second cooling fan is closed; and when the absolute value of the difference value of the measured values of the first and second light intensity sensors is greater than a set threshold value and the measured value of the second light intensity sensor is greater than the first light intensity sensor, the first cooling fan is turned off, and the second cooling fan is turned on.
Therefore, the first light emitting module and the second light emitting module are the same and symmetrical relative to the baffle, so that theoretically the measured values of the first light intensity sensor and the second light intensity sensor should be slightly different, if the measured values are greatly different, the damage of the light emitting module on the side with the small measured value is indicated, and the damage condition of the lamp cap can be reminded to maintenance personnel by matching with the on-off of the first indicator lamp and the second indicator lamp. And when the lamp holder is not damaged, the first cooling fan cools the first light-emitting module, and the second cooling fan cools the second light-emitting module, theoretically, the measured values of the first and second light intensity sensors should be not different, if the measured values are different greatly, the light-emitting module on the side with the small measured value is damaged, and therefore the cooling fan on the side is turned off. At this time, the light emitting module is damaged, and the heat productivity is small, so that a heat radiation fan does not need to be specially started for heat radiation, and the energy is saved. The situation that the two light emitting modules are damaged simultaneously (the difference between the measured values of the first light intensity sensor and the second light intensity sensor is not large at the moment) is not considered in the invention, because the possibility of the situation is low, and the two light emitting modules are damaged simultaneously, maintenance personnel can see at a glance that the intelligent indicating lamp prompting scheme is not required to be designed.

Has the advantages that: the lamp cap of the street lamp is provided with the two light emitting modules, and the distance between the two light emitting modules is adjustable, so that the overall irradiation angle and range of the lamp cap are adjustable. Therefore, the street lamp can meet the irradiation requirements of road surfaces with different widths.
