The headlights are blocked to ensure safe driving.

At this time, a reflector that is reflected by the headlights of a running vehicle is mounted on the light blocking film so that the center divider can be easily identified by the reflector even when the vehicle is running at night.

However, the surface of the reflector is easily soiled by dust or fumes generated by the vehicle, so that even when irradiated with the headlights of the vehicle at night, the reflector does not function properly and is not easily identified even in bad weather. As a result, the driver at night It has a problem that traffic accidents frequently occur because the median divider cannot be identified. In addition, there is a problem in that the reflector cannot be reflected unless the light of the headlight is received at a right angle.

On the other hand, since streetlights are not installed on the road where the median divider is installed, it is difficult to check the traffic condition of the road ahead at night, and thus traffic accidents are increasing.

On the other hand, in the case of sunshades using photovoltaic power generation, when cloudy days continue or when the amount of sunlight generated is low, even the current of the battery protection device is exhausted, making it impossible to charge normally. there will be no In this case, in order to drive the system again, the worker cycles through the streetlights one by one, and the BMS supplies a certain voltage to the battery through another normal battery to restart the system.
