Overview

As energy efficiency becomes increasingly important for controlling costs, improving energy independence and reducingenvironmental impact, street lighting using advanced technology like the LED (Light-Emitting Diode) and enhanced HID (High Intensity Discharge) could become the world's leading technology to meet energy conservation objectives. Compared with traditional HPS (High-Pressure Sodium) streetlights, these new streetlight solutions also provide improved life cycle cost and better color rendering. Therefore, more and more cities adopt the environmentally friendly and energy efficient lighting solutions without compromising illumination quality.TechnologyWith the embedded sensors in the light head, streetlights can automatically switch on/off according to the outside conditions. When full lighting is not required, they can also automatically dim and adjust for energy efficiency. Furthermore, the technicians can monitor and control the streetlights via the Billion So-Max advanced wireless network through a web-based communication system.Challenges The initial cost of implementing an advanced streetlight system is higher than traditional HPS lights. Ease of installation could be a key factor that affects the success or failure of the implementation.

Main

problem of street lights are not working properly and power wastage is more due to street lights glowing continuesly b/s for switching off the street light there is a need of a man or a worker who switch it off. Sometimes the workers not doing his responsibility properly. So from this, the light is waste so much. Light turns on when shadow falls on LDR and LED and the challenges of this technology ease of installation could be a key factor that affects the success or failure of the implementation.

we have find the solution for the problem that is design intellegent street lights control system. This is working by using LDR’s. The LDR is a resistor and its resistance varies according to the amount of light falling on its surface. When the LDR detect light its resistance will get decreased, thus if it detects darkness its resistance will increase so streetlights can automatically switch on/off according to the outside conditions. it is energy consuming project and there is no need of any worker for switch off or on the street light. It is eco –friendly and low of cost. It consume so much energy. The other solution To design a model that would implement the system’s operation and to test and analyse the system.(
