The First LED Solar Road Stud Marker in China

China's first traffic lights appeared in Shanghai. Some data show that in 1928, Shanghai public concession began to use mechanical devices to indicate vehicles to stop and move forward. On April 13, 1928, traffic lights were first installed at two important intersections of Nanjing Road. According to records, the traffic lights in Beijing first appeared in Xijiaomin Lane in 1932.

The advantages of LED solar road stud markers in energy saving is very obvious. One of its obvious characteristics is low energy consumption. Almost 100% of the excitation energy of LED traffic lights becomes visible light, compared with 80% heat loss of incandescent bulb, and only 20% of it becomes visible light.
The other advantage of LED solar road stud markers is high brightness. The reflection brightness of ordinary reflective road stud markers is only 300-400 MCDs, while the luminous brightness of solar solar road stud markers can reach more than 2000 MCDs, which is 6-7 times of the former. High intensity light can break through the rain and fog at night and guide the driver safely and effectively.

Active lighting and dynamic warning is also a advantage of solar solar road stud markers. Solar solar road stud markers flash at a certain frequency at night, and human vision is more sensitive to changes, so its dynamic warning function is very strong. Active luminescence can not only avoid the interference of rain and fog to the greatest extent, but also can be separated from the dependence on the car lighting, the visual distance is longer and the effect is better.
Solar solar road stud marker plays a very important role in the rain and fog weather and in the curve to draw the road outline, guide the driver's line of sight, and then eliminate the potential safety hazard.
