The Research Of Intelligent Lighting Wireless Technology Control System Of LED Based On ZigBee

Nowadays,the concept of environmental protection has been deeply rooted in people's heart,energy conservation and emission reduction has become the consensus of the whole society.As lighting is an indispensable part of people's live,the application of green lighting will greatly promote the process of energy reduction and help build a conservation-oriented society.LED is a kind of green and ideal light source with the advantages of low energy consumption,small volume and long service life.The intelligent lighting technology,which is based on LED technology and wireless control technology,is the key to realize the "networked,intelligent and standardized" of the lighting control system.Among wireless technologies,Zig Bee technology is now widely used in our daily life because of its low power consumption,low cost,large network capacity,ad-hoc network and other features.It can connect devices distributed in home which contains Zig Bee node through the Zig Bee network.When combined with Wifi,a technology with high rate and can be connected directly,it can connect the lighting system to home network,thus achieve control over lighting system via all intelligent control terminals.An excellent intelligent lighting system can improve people's work efficiency and improve the quality of living environment.This paper will study the intelligent lighting system from two aspects: the design of high quality light source for the system and the design of intelligent control system which is easy for management.Specific contents are as follows.First of all,we analyze the development of intelligent lighting and learn related knowledge,then give the design scheme of Zig Bee-Wifi gateway + Zig Bee intelligent lighting devices + Intelligent Client.According to the characteristics of intelligent lighting,we design a RGB lamp and transform the structure of traditional substrate;to adjust the lighting brightness and color temperature,we put forward a new method to obtain the gray value.Secondly,we design and make the hardware of the Zig Bee-Wifi gateway and Zig Bee intelligent lamps.Thirdly,based on the Z-Stack protocol stack,we design the embedded software on the IAR platform,and realize the functions of network communication and dimming control.Finally,we use Qt Creator to design monitoring software for PC client.With the system debugged and combined into network,users have had effective control over it via intelligent control ports.It shows that both automatic mode and manualmode run normally.Color,color temperature and luminance can be adjusted independently.Color temperature-temperature compensation lighting,constant illumination reach expectations.
