Description
technical field [0001] The invention relates to a road traffic prompting device, in particular to a road traffic prompting device on a vehicle roof. Background technique [0002] At present, with the increase of the global population, the increase of energy consumption has become an urgent problem to be solved by the international community. Since solar energy is clean energy and renewable energy, solar energy products have been widely used in production and life, such as solar power stations, solar energy Street lamps, etc., such large-scale solar energy-utilizing equipment cannot provide the awareness of the general public to utilize solar energy. [0003] Solar energy utilization is used in large-scale projects, and it seems too far away to use solar energy for some small devices that need to be placed or worked outdoors for a long time. [0004] Especially for road construction and traffic maintenance, it is necessary to quickly provide various road information promptin...
