In the early morning, photovoltaic panels store energy in the sun; at night, warm white halos cover the road, illuminating people returning late, so that they don't have to grope for roadblocks in the dark. The integrated design requires no external power supply, and park operation and maintenance personnel do not need to conduct frequent inspections. They only need to watch it turn on steadily during the four seasons-it is a silent support and a standard feature in an efficient park.
