The background of solar road studs is that the focus of highway construction is gradually shifting to mountainous areas and mountainous areas where economic development is relatively lagging. On highways in mountainous areas, the wind speed is more significantly affected by mountains and valleys. The humid and rainy climate, coupled with the lush forest environment, often produces fog in this section of the road. And highways usually span a long distance, especially many highways passing through rural and mountainous areas, which makes the situation of highways relatively complicated. The distribution of fog is often very uneven, and sometimes the line of sight is quite clear on a section of road. The other section was heavily foggy.
Since this situation usually occurs at night, when a high-speed vehicle suddenly enters a foggy area, the driver's vision will suddenly become darker. Some drivers can not adapt to sudden changes in vision, they will have a sense of panic, which is easy to cause a traffic accident. The high visibility and luminous intensity of solar road studs can effectively improve driving safety on the road.
Solar road studs are a kind of road studs, which are set along the road surface and are used at night or in rainy and foggy weather to indicate the direction of the road. It is composed of retroreflective material, shell, solar panel, LED and control device. Solar road studs have visual induction facilities with active light-emitting and passive light-reflecting properties, and are usually used in combination with markings.
The working principle of solar road studs can be briefly summarized as follows: During the day, the solar panels of solar road studs absorb sunlight, convert solar energy into electrical energy, and store it in energy storage devices (batteries or capacitors). At night, the electrical energy in the energy storage device is automatically converted into light energy (controlled by a photoelectric switch), and the outline of the road is drawn by the bright light of the LED to induce the driver's sight.
