The utility model relates to a biax solar street lamp photovoltaic cell board pursues light device solves the lower problem of solar street lamp solar energy utilization ratio. Solar cell panel support passes through the bolt and is connected constitution panel fixing device with the worm -wheel shaft, worm and gear transmission mechanism is constituteed in worm -wheel shaft, worm axle and worm wheel cooperation, consider environmental factor, the street lamp device needs to bear strong gale power, consequently under the condition of guaranteeing each parts intensity of device, to installing the whole machine design that has gone on. The high angle drive device that designs adopts worm gear kind of drive, and gear motor selects standard planet speed reduction step motor for use, transmits panel bracket parts with gear motor's rotation through the worm gear deceleration device, realizes the motor and controls photovoltaic cell board elevating angle pivoted. Through gear motor and planet gear realization speed reduction purpose, the rotation of photovoltaic cell board azimuth direction has been realized.
