The invention provides a regional loop controller in an intelligent road lighting system. The regional loop controller, a PC (personal computer) machine and a scene node controller form a road lighting control system which can sense external environment change and a lighting system service body in real time, and can provide high lighting quality in remote. The regional loop controller is connected with the PC machine and the scene node controller, and is the pivot of the intelligent lighting control system; and the regional loop controller and the scene node controller form a master-slaver structure, and analyze and realize control strategy and management information query of the PC machine. As shown in the figure, the regional loop controller comprises a power supply module, a control core, a clock module, a human-computer interaction module, a control module selecting module, a system setting module, a diagnose interface, a communication module, a traffic information acquisition module, an external information acquisition module and a display module interface. The regional loop controller, the scene node controller and the PC machine form an integrated novel application system which is high-efficient in lighting, intelligent in control, energy saving and consumption-reduction, and lights according to needs.
