ABSTRACT:

Scientific inventions have made this world worth liv- ing. They have provided us with various means of comforts and luxuries. The invention of electricity is one of the greatest of its wonders. Indeed, we can- not even dream of living in absence of electricity in modern times. There is no walk of life in which it is not used these days. Some of the more important of its uses are given below. We now light our lamps with electricity. Switch on the button and there is the day- like light even in the darkest night. Through such a system only they did avoid the power wastage. So we are in need of an effective system for power conserva- tion. LED light source is gradually to the replacement of traditional lighting equipment with high power consumption. Meanwhile, the “next-generation light source” matching intelligent lighting control system is produced. Today several wireless technologies are used for building wireless networks. Among them the 2.4GHz wireless network is most widely deployed and used.

The wide usage of 2.4 GHz wireless communication in- dicates that this infrastructure can give near real time responses and makes suitable for crucial industrial monitoring systems.ZigBee also helps save time and cost in the installation of office lighting fixtures.

Instead of hiring an electrician to install new electri- cal wiring and dimmers, ZigBee enabled lights can simply be plugged into any ac outlet and then con- trolled wirelessly by a ZigBee controller. LED lighting control system based on the Zigbee wireless network is a combination of Zigbeersquo;s advantages in wireless network and short-range wireless transmission and LEDrsquo;s characteristic of high lighting efficiency and low power, it is not only security, intelligence, easy to con- trol, but also engineering convenient in wiring and maintaining. It has good applicability in interior illumi- nation and road lighting engineering.

INTRODUCTION:

The LED light control system implimented based on the 2.4GHz zigbee wireless Modules , ARM7 , PIC18F microcontroller and few sensors.This system consists of two parts, respectively for Trasmitter module and a Lighting modules. The major components of Trasmit- ter module include main control chip PIC18F452 , Zig- bee RF transmission system, 4x4 matix keypad, mode selection keys and a LCD screen. 4x4 Matrix keypad will helps us to access the password based authenti- cation. User can send commands to the controller by the mode selsction keys, and the data will be trans- mitted by the ZigBee modules. Receiving Lighting module consistes of ARM7 Microcontroller, led driv- ing circuits, sensors.

The data will be transformed into the corresponding

PWM signal when receiving module receives the or- ders from the sender, then, the PWM signal is trans- ferred to the LED lighting terminal, which makes lighting terminal produce the presupposed lighting effects.In the proposed system, the user is provided with list of functions. LCD will display the function se- lection menu. According to the needs of application and demonstration, user may select different func- tion, for that they are provided with keypad. There are Five mode of operation:

1)Normal PWM dimming (Photo electric) 2)Self-Adaptive dimming (Temperature) 3)Timing dimming (RTC)

  1. Self-Adaptive dimming (Photo electric and RTC)
  2. Automatic Mode (Temperature, Photo electric and RTC)

Through the Zigbee network, the receiver receives the command signal and executes corresponding func- tions. When the user selects in the selection menu, the receiver will startup ordinary dimming mode. When the coordinator sends illumination level again, the receiver will produce pulse signal with different Duty-cycle to control the luminance of LED lamps, thereby achieve multilevel diming. When the user se- lects 2 in the selection menu, the receiver will startup self-adaptive dimming (Temperature) mode.
