PROJECT DESCRIPTION

The project is designed for LED based street lights with auto intensity control using solar power from photovoltaic cells. As awareness for solar energy is increasing, more and more individuals and institutions are opting for solar energy. Photovoltaic panels are used for charging batteries by converting the sunlight into electricity. A charge controller circuit is used to control the charging.

 Intensity of street lights is required to be kept high during the peak hours. As the traffic on the roads tends to decrease slowly in late nights, the intensity can be reduced progressively till morning to save energy. Thus, the street lights switch ON at the dusk and then switch OFF at the dawn automatically. The process repeats every day.

High Intensity Discharge lamps (HID) used for urban street light are based on principle of gas discharge, thus the intensity is not controllable by any voltage reduction method as the discharge path is broken. LED lights are the future of lighting, because of their low energy consumption and long life they are fast replacing conventional lights world over. White Light Emitting Diode (LED) can replace the HID lamps where intensity control is possible by pulse width modulation.

The intensity control helps in saving energy during late nights while traffic density on the streets is low. A programmable ARM cortex processor STM32 family is engaged to provide different intensities at the different times of night using PWM technique, for energy saving for solar based system, using a charge controller for battery charging, overload and deep discharge protection.

Further the project can be enhanced by using time programmed dusk to dawn switching based on latitude and longitude of a specific place. It can also be interfaced to a LDR to follow the switching operation precisely.

Q & A
Q:  What is the auto intensity control?
A:  Automatically controlling the intensity of street light according to the peak traffic hours in the night time and completely switching off at the day time is auto intensity control.
Q:  Which kind of street lights is used in this project?
A:  String of white LEDs are used which are comparatively far better than HID lamps
Q:  What is the concept used in this project?
A:  PWM technique is used in this project.
Q:  Can I use a higher rating Solar Panel?
A:  Yes, a solar panel with rating limited to 6V, 20W can be used.

Yes the kit reached me on time with all the components.I followed the CD and it is very useful.Initially it was difficult to build the project but at the final I got it with the help of my batch mates.Yes I had recommended to my class mates.
