Solar Road Stud
The solar road stud is the traffic safety product that uses the solar panel as the charge device, battery or electric capacitance as the energy storage device and the light of the stud is given out through the LED. According to the demands of the Ministry of Transportation, the pressure resistance of the solar road stud should be over 100KN. The solar road stud is set along the road, and it can be applied to delineate the way at night or in rainy or foggy days. Its visual effect is better than the ordinary road stud, and it is always applied together with the marked lines on the road.The solar road studs can be divided into two types according to the energy storage device: the solar road stud (battery) and the solar road stud (energy capacitance).
The solar road studs can be divided into two types according to the color of the LED: the solar road studs of red and yellow, and the solar road studs of white, blue and green.
The working principle of the solar road studsThe solar panel of the solar road stud absorbs solar energy, which can be transformed into electric energy and stored inside the energy storage device, like battery or electric capacitance, in the daytime, and the electric energy inside the energy storage device can be transformed into light, which can be controlled through the photoelectric switch, at night.
The light is given out through the LEDs to delineate the way and guide the sight of the drivers.The solar road studs can be divided into the embedded type and raised type according to the difference of installation site.The former one is always installed in the central line, and the latter one is installed in the edge of the road.
For the solar road stud installed in the central line should have strong pressure resistance, and the solar road stud can only be embedded underground and only 5mm above the ground; the solar road stud installed in the edge of the road does not have strict demands on pressure resistance, and it can work effectively even raised on the ground.
The solar road studs can be divided into the capacitive type and the battery type according to the difference of the energy storage elements of the solar road studs, and the service time of the former one can be 2 to 3 years, and that of the latter can be 1 to 2 years.
For the embedded solar road studs damage the surface of roads greatly, and the cost of the capacitive solar road studs is high, so the embedded capacitive solar road studs are widely applied in our daily life now.
