The road stud includes lamp body ,bottom cover ,solar panel ,control panel ,battery and 6pcs led .It is mainly installed on the lane line, which can automatically light up at night to clearly indicate the lane, and can also indicate the direction of the lane to prevent the wrong lane.
How it works:
During the day, the solar panel absorbs sunlight, converts solar energy into electricity, and stores it in the energy storage device (battery or capacitor). At night, the energy in the energy storage device is automatically converted into light energy (controlled by photoelectric switch), and the LED gives off bright light to outline the road and induce the driver's sight.
