(2) The two-way control has poor cooperativity, namely, the control logics of the two independent power supplies are mutually independent, the linkage control of two-way illumination (such as synchronous dimming and peak staggering energy saving of a road bidirectional street lamp) cannot be realized, and the shunt controller can only realize simple on-off control and cannot meet the two-way differential dimming (such as different brightness requirements of a factory production area and a channel area). (3) The wiring is complex and has high cost, the power supply and the control module are independently deployed, and control circuits are required to be additionally paved, so that the construction difficulty, the material cost and the later maintenance cost are increased, and the wiring complexity is exponentially increased especially in the scenes of road illumination, large industrial workshops and the like. (4) The energy consumption is high, the traditional power supply conversion efficiency is generally between 85% and 90%, the line loss between the control module and the power supply further reduces the energy utilization rate, and meanwhile, the dimming control mostly adopts an analog dimming mode, and obvious power loss exists in the dimming process. (5) The operation and maintenance efficiency is low, the state monitoring of the power supply and the state monitoring of the control module are mutually independent, the problem of difficulty in quick positioning is required to be checked when faults occur, the remote control capability is lacked, the operation and maintenance personnel need to operate on site, and particularly, the operation and maintenance difficulty is extremely high in scenes such as remote roads, high-altitude illumination and the like. (6) The intelligent illumination management platform has poor functional compatibility, communication protocols among power supplies and control modules of different brands are not uniform, the intelligent illumination management platform is difficult to dock, additional functions such as human body induction and illumination induction cannot be flexibly expanded, and the suitability is limited.
