Shandong solar street lamps refer to lamps that provide lighting functions for roads. Shandong solar street lights can be seen everywhere, but only on the expressway. Why? Are you worried about traffic accidents? What is the reason?

Cause 1: The cost of installing street lights on highways is high

The high cost of installing street lights on highways is easy to understand. The installation distance of street lamps is generally 30 meters to 40 meters (of course, the specific distance depends on the actual situation). If the 50 meter street light is regarded as hundreds of kilometers on any expressway in China, the street light will be installed. The cost of street lamps is very high. The cost of electricity is astronomical. Some people will say that Shandong solar street lights can be installed. Yes, but the cost is also high. In addition to the subsequent maintenance/repair, the cost is also high.

The second reason is that the safety factor of expressway is high

Freeways are closed roads connecting cities. In the absence of pedestrians and non motorized vehicles, urban street lights are designed for the safety and convenience of non motorized vehicles and pedestrians. The service functions of the two are different, so it is not necessary to set street lights all the time, but only necessary parts, such as tunnels and death curves. In addition, the road surface is flat without obvious tunnels, the road condition is good, and the safety factor is high.

The third reason is that car headlights and road reflective signs are sufficient to meet the lighting needs

Shandong solar street lamps are discontinuous and uneven. For drivers of high-speed vehicles, this kind of light dark alternation will cause visual illusion, which is very dangerous. In addition, it can quickly cause eye fatigue. Poor street lighting and scattered light will dazzle and confuse the driver during long distance driving and cause driving safety hazards. When the external lighting is insufficient, the vehicle headlights can provide the driver with safer lighting. Since the oncoming car has no obstacles, you can drive the high beam at night.

To sum up, it is neither scientific nor safe to install Shandong solar street lights on expressways.
