The device utilizes photosensitive sensors and AI algorithms to achieve environmental adaptive adjustment. It supports dynamic coordination among multiple drones, precisely controlling brightness, color temperature, and beam angle, thereby breaking through the limitations of traditional fixed lighting equipment. In practical applications, its efficiency is 90% higher than traditional methods, while labor costs and equipment costs are reduced by 70% and 50%, respectively. It is capable of seamlessly covering large areas of complex terrain, significantly enhancing the operational safety and efficiency of tasks such as power grid emergency repairs, firefighting and rescue operations, and engineering construction.
