English:
solar road stud or solar road marker. It is a kind of
road stud, set along the road surface, used at night or in rainy and foggy weather to indicate the direction of the road. It is composed of retroreflective materials, shells, solar panels, LEDs, and control devices. It has active luminous and passive reflective properties. The visual inducement facilities of the city are usually used in conjunction with markings. Edit this paragraph’s background The focus of expressway construction is gradually shifting to mountainous areas and mountainous areas with relatively lagging economic development.
In mountainous expressways, the wind speed is significantly affected by mountains and valleys, with an average wind speed of only 1.2 m\/s, and wet and rainy weather conditions. Coupled with the lush forest environment, there is often fog in this section of the road. And because expressways usually span a long distance, especially many expressways pass through rural areas and mountainous areas, the situation of expressways is relatively complicated. The distribution of fog is often very uneven, and sometimes the line of sight is quite clear on one section of the road, but heavy fog on another section. Because this situation usually occurs at night, when a high-speed vehicle suddenly drives into a foggy area, the driver will feel that his vision suddenly becomes dark. Some drivers cannot adapt to the sudden change of vision, and they will have a sense of panic, which is easy to cause Traffic accident.
The visibility on the highway in foggy days is only 300-400 MCD, while the luminous brightness of
solar road studs can reach more than 2000 MCD, which is 6-7 times that of the former. The high-intensity light can penetrate rain and fog at night, which is safe and effective. Provide directions for the driver. Active lighting, dynamic warning solar road studs flicker at a certain frequency at night, and human vision is more sensitive to changes, so its dynamic warning effect is very strong. Active lighting can not only avoid the interference of rain and fog to the greatest extent, but also can break away from the dependence on car lights, and the visual distance is longer and the effect is better.
Solar road studs play a very important role in delineating road contours in rainy and foggy weather and at corners, inducing the driver's sight and eliminating potential safety hazards. During the day, solar panels 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 devices is automatically converted into light energy (controlled by photoelectric switches). The LEDs emit bright light to outline the road and induce the driver's sight. Ensure road safety!
