Solar traffic signal lamp

The invention discloses a solar traffic signal lamp, which comprises three light poles. A control circuit is installed on the bottom of the first light pole, and a maintenance window is opened at a position corresponding to the installation position of the control circuit. There are speakers and a horizontal light arm, the horizontal light arm is detachably connected to the second light pole, at least three groups of first traffic lights and cameras are arranged on the horizontal light arm, solar panels are set on the third light pole, and the control The circuit includes a solar panel, a DC/DC step-up circuit and a battery connected in sequence. The output terminals of the battery are respectively connected to the traffic signal light control unit and the capture unit. The capture unit is respectively connected to the image collector, fill light, image compression module, and network The transmission module is connected with the light intensity sensor. In the present invention, the traffic signal lights can be easily disassembled through the arrangement of multi-section light poles, which facilitates transportation and installation. The bottom of the light poles is equipped with a control circuit and an inspection window to facilitate the maintenance of traffic signal lights. The traffic signal lights are powered by solar panels, green energy saving.
