Reflective road stud on motorway is a kind of traffic safety facilities, which can reflect the car lights, prompt the obstacles in front of the driver and mark the edge of the road. Reflective road stud on motorway is developed from cat’s eye road stud, but it still has its shortcomings.
For example, the light intensity of reflective road stud on motorway is insufficient, generally only about 200mcd. For fast-moving cars, the warning effect of reflective road stud on motorway is not very effective. And the reflective road stud on motorway is passive light, it will not work when there is no car light.

Compared with reflective road stud on motorway, solar road stud on motorway has many advantages. Let’s take a look at the solar road stud on motorway.
According to experts, the working principle of solar road stud on motorway can be simply summarized as: solar panels absorb sunlight during the day and convert solar energy into electricity. In the evening, the electric energy in the energy storage device of the solar road stud on motorway is automatically converted into light energy, and the road outline is drawn by emitting bright light to guide the driver’s line of sight.

Compared with ordinary reflective road stud on motorway, solar road stud on motorway has two most important characteristics: first, the luminous brightness of solar road stud on motorway is more than 10 times that of ordinary reflective road stud; such a high intensity of light can break through the rain and fog at night and guide the driver safely and effectively. Second, the solar road stud on motorway can be active light, flashing at a certain frequency at night, strong dynamic warning effect. Active lighting can not only avoid the interference of rain and fog to the greatest extent, but also break away from the dependence on car lighting, with longer visual distance and better effect.
