[Abstract]:Absrtact: in recent years, the advantages of energy saving and high efficiency, long life of LED lamps have been obvious, combined with its characteristics of intelligence, there is still wide space for network development and application. Based on the enterprise innovation fund project of "Intelligent LED Lighting", this paper designs and develops the high-power LED switching power supply and its networked control system. (1) the principle structure of the driving power supply is carried out with the development of the high-power LED driving power supply as the goal. Control scheme, electromagnetic compatibility and reliability research. The control parameters of single power supply and intelligent dimming control strategy are put forward, and the related hardware and software are designed. (2) the topology structure, networking strategy and data communication protocol of multiple LED drive power sources are studied. Based on the protocol and architecture of JenNet-IP wireless technology based on IEEE 802.15.4, the network application of environmental illumination control is proposed. The system design and software programming are carried out. (3) the experiment and design of the power module and the netting system are carried out, respectively. The LED lamp luminous under the power drive power supply of .50W is stable, the power factor is maintained above 0.94, and the efficiency of the whole machine is about 92%. With the help of the system network, the timing control based on illumination or time parameters is realized in the lighting environment of remote dimming operation and multi-lamp combination. Through experimental analysis and test results, the parameters such as voltage, current, power factor, efficiency of switching power supply and the effect of energy saving control strategy based on environmental illumination are achieved. The feasibility of the system and the realization of the basic function are verified.
