Road lighting device, distributed node energy-saving lighting system and method for operating same

摘要

A road lighting device, a corresponding distributed node energy-saving lighting system and a method for operating the same. The road lighting device is connected to a light source (111) and has a power module (112). The road lighting device further comprises a sensing control unit and a communication control unit, wherein the sensing control unit enables the light source to be in a normal lighting state according to a vehicle signal, and the communication control unit enables the light source to be in a normal lighting state according to broadcast information containing a triggering instruction code. The sensing control unit and the communication control unit can separately or jointly control the light source, thus achieving intelligent control, rendering it possible for each road lamp equipped with such a road lighting device to independently carry out intelligent judgment on road usage and carry out dynamic energy-saving adjustment in real time, so as to ensure necessary useful illuminance and eliminate useless illuminance as far as possible. By using the distributed node energy-saving lighting system and the method for operating the same, all the road lamps are interconnected to form a network, thereby achieving intelligent automatic identification of failure and information feedback, as well as remote intelligent management and point-to-point control.
