Research On Complementary Lighting Technology Of LED Light And Natural Light

With the progress of information technology,the concept of the Internet of things and the flourishing development of the LED industry,the traditional lighting scheme with single function and high power consumption can not meet the growing needs of life.People are gradually using LED instead of traditional lighting system.With the rapid development of computer network technology and wireless sensor technology,the Internet of things technology is also widely used in indoor lighting system,forming intelligent lighting technology,and complementing natural light to carry out indoor lighting has become a trend of development,in line with the concept of "energy conservation,low carbon life" which is advocated by the state.In this paper,an indoor intelligent lighting system based on ZigBee wireless sensor network is proposed,which mainly focuses on the research of the complementary lighting technology of the indoor LED light source and natural light.With the combination of ZigBee wireless sensor network technology and the topology of ZigBee network protocol stack,the environment illumination of each LED lamp in the room is collected in real time,and the function of the scene mode and indoor lighting adjustment is realized through the analysis and judgment of the control system.The main work of this paper includes the following points:Firstly,ZigBee node design.The system uses a ZigBee network system composed of a ZigBee coordinator node and several ZigBee terminal nodes,in which each ZigBee terminal node is connected with a BH1750 illuminance sensor,which is responsible for the illumination collection in the indoor environment.And the data is sent to the coordinator through the ZigBee terminal connected by it for corresponding data processing;Secondly,Design of upper computer.The upper computer is a real-time user management system developed by Qt software(cross-platform C graphical user interface application development framework).This computer can select and controlthe illumination of any situation in the indoor environment.Thirdly,Computer simulation and simulation.Using the current laboratory environment,the field modeling of the laboratory environment is carried out,and the lighting environment simulation is carried out by combining with the lighting assistant software,DiaLux scheme of LED light source and natural light complementary lighting is put forward.Finally,System testing.Test each module of the system,including LED driving module of illuminance sensor and network test of ZigBee network,and debug the system as a whole,compare the simulation results with the test data,analyze and analyze the simulation results and the test data.Finally,the whole experiment result is analyzed and evaluated.
