Compared with ordinary reflective road studs, solar road studs light have two most important characteristics:
The reflective brightness of ordinary road studs is only 300mcd to 400mcd, while the luminous brightness of solar road studs light can reach 2000mcd, which is 6 to 7 times of the former. Such high-intensity light can penetrate the rain and fog at night and guide the driver safely and effectively.
The solar road studs light flashes at a certain frequency at night, and its dynamic warning function is very strong. Active light-emitting can not only avoid the interference of rain and fog to the greatest extent, but also let the driver's vision get rid of the dependence on the car's lights. The visual distance is longer and the effect is better.
Working principle of road stud light on road:
The working principle of solar road studs light can be summarized as follows: solar panels absorb sunlight during the day, convert solar energy into electrical energy, and store it in energy storage devices (batteries or capacitors). At night, the electric energy in the energy storage device is automatically converted into the light energy (controlled by the photoelectric switch), and the light is emitted by the led to outline the road and guide the driver's line of sight.
According to the different installation position, road stud light on road can be divided into two types: embedded type and raised type. Because of the high requirement of the compression resistance of the solar road studs light installed in the center line of the road, the former is generally used in the middle line of the road, and the latter is mostly used in the edge line of the road.
According to the different energy storage components, the road stud light on road can be divided into two types: capacitance type and battery type. The service life of the former can reach five to seven years, while that of the latter is generally one to three years.
The embedded solar studs light do great damage to the road surface, and the cost of the capacitive solar studs is too high.Therefore,the most widely used solar road stud in the industry is the raised battery type solar road stud light at ptrsent.
