Research And Analysis Of Wireless Dynamic Lighting Network Technique

As the intelligent and digital control modes are used in the life of human beings, lighting network becomes an apart of large-sized stage illuminating engineering, building automation, intelligent homekeeping and so on. Present lighting networks have disadvantages like small network capacity (lighting circuit), uncontrolled light brightness, uncomfortable light feeling and difficult system controlling and so on. The early network planning and layout makes the construction of the lighting network more complex.So there should be a new lighting network to replace the current network. Wireless dynamic lighting network is a new type of lighting network, which has light control ability and based on the network reconfiguration and human engineering in the environment. The wireless lighting network given in the paper builds on the ZigBee[ 1 ] wireless communication technique and constructs a network framework with good network organization, expandable network topology and route automatic selection and other advantages.This paper finished the research and analysis of wireless dynamic lighting network technology on the dynamic lighting network conception.
