INTRODUCTIONRenewable energy sources plays an

important role in electricity generation. it is available everywhere and is free to

harness. It is also used in street lights

SOLAR PANEL4.5 TO 5VIt convert light from

the sun into electric current through the photovoltaic effect.

DYNAMO

A dynamo is an electrical generator that produces direct current with the use of a commutator

2.5 to 3v It generates the required energy through speed breaker

APPLICATIONS AND FUTURE ENHANCEMENT

APPLICATIONS1.This system is designed for outdoor applications in un-electrified rural areas.

2.This system is an ideal application for campus and village street lighting.

3.Solar street light system is an ideal lighting system for roads, yards, residential colonies, township, corporate offices, hospitals educational institutions and rural electrification. FUTURE ENHANCEMENT

There is always chance to improve any system as research & development is an endless process. Our system is no exception to this phenomenon. The following developments can be done in future for Speed Break Based Street Light Control: In future this module can be implement to activate the Street Lights based on the number of persons arrived. 

ADVANTAGES

In general mode, the power savings is about 50% .

In dim mode, it is about 35%.

Using LED’s in this technology, it provides cool

environment unlike HID lamps.

Utilization of energy is optimized using this

technology.

Street light gives a bright light over a semi circle of

radius 30 feet.

DISADVANTAGES

Operative and maintenance is cost effective.

Initial and maintenance cost is high. 

CONCLUSION This concept falls under the subject of non-

conventional energy resources, out of the many

alternative energy resources one dependable

source is solar energy, but it is quite costliest

affair. Therefore, alternative cheapest source is

to generate electricity from speed breaker. This

technology proven here is the ultimate

inexpensive source of all known forms of energy
