Muti-effect Intellighent Lamp Design In Indoor Lighting System Based On ZigBee Technology

Nowadays most of the intelligent light system use the cable network,this kind of network is difficult to move and complex construction.Compared with the wired control,wireless control system has so many strengths,like easy to move,flexibility and lower price.Currently there are many wireless communication technology,the most commonly used are Bluetooth,Wi-Fi and ZigBee,at these wireless communication technology,ZigBee has incomparable advantages at build up large-scale ad hoc network,lower power dissipation and lower price,because of these advantages ZigBee is widely used at intelligent light systems.Traditional lamps just have the simple functions and the brightness is all predefined.With the improvement of people's living standards,these kinds of lamps can't fulfill commands.People wish the lighting system are more intelligent and user-friendly,and can incorporate it with daily life.Based on these requirements,this thesis designed an intelligent lamp,except can change brightness,and also have various color selection,different color temperature.Besides that,according to different functions and places,can set the different scenes,for example,when people have reset or at bedroom,the brightness can lower or set to warm white;when working or at the studying room,the brightness can set to the maximum dimming level or cold white.This thesis designed the lamp wireless communication through ZigBee,this way can avoid the complexity of line control.For the hardware parts,use the red,lime and blue LED to design,compared with the WRGB four kinds of LEDs,use lime instead of blue and white led,can save the money and also provide the sufficient brightness.Use one kind of chromatic algorithm,by doing them,theoretically this lamp can have reached to 1.6 million colors.Designed base on ZigBee Light Link profile,and use the CC2530 chip to realize ZigBee communication.The stack is used the Z-Stack which developed by TI.Use the PC control software can let user easily control lamps,change colors or set scenes etc.
