4. INTRODUCTION
Purpose of the Project: To overcome excess energy
consumption due to street lights in a wide area and real time
monitoring of individual street lights
What the project does to fulfill the purpose:
1. Solar energy.
2. Power LED’s .
3. Wireless transeceiver .
5. LITERATURE SURVEY
Communication system for street light controller
• PLC Communication System
Remote controller
wires and repeaters
• TinyMesh
Low price
Low data rate – 10kbps, sufficient for application
Low power consumption
Reliable.
6. LUMINARIES
Low power discharge lamp
Uses inert gas and small quantity of mercury
High efficiency and economy
Difficult to control the distribution of emitted light
High intensity discharge lamps
Uses electric arc between tungsten electrodes
High level of light over large area
Costly to produce, install, purchase, repair
7. CONTINUED..
LED – Light emitting diode
Compact size
Very high lumen output
Vibration resistance
no filaments
No UV or IR emissions
50-90 % less energy
consumption.
