How to reduce energy consumption in street lighting?

for saving energy connsumption in street light , there we use solar plates & using CLF bulbs which consume less energy.other this we use sensors for on/off the lights, means when light intensity are low that time bulbs on and when light intensity is more thats time this gets off and the distance between two strret pole and hight of poles are affect the energy consumption so by this use we reduce energy consumption in street light.

 we can reduce energy by impliment of solar system

2 implement  Auto meaching syste oppreating system reference to trafic light auto on and auto  off after night odd time

Daylight saving helps a lot to reduce the consumption of power for lighting.

India should take to daylight saving.

Use of solar powered and wind powered lamps is also the long term solution.

Timer device may be incorporated so that ON & OFF of the lights occur at pre set time.

CONTRACTORS should opt for light coloured roads or Concrete pavements. By constructing this type of roads the visibility in the night will be very good and also reduces the dependancy on ARTIFICIAL LIGHTING.

for street light if we used solar power more expensive.why we can use LED with good reflecting layers

As Mr. Anup said, Why cant we use the solar energy. In the emergency light this simple technique is used. So if we get energy from the solar , when can use that when its not there. So the day timing we produce or save energy and in night we can utilise that. A sensor its helpful for the maintanance.

energy efficient light is to be used in street light  which will save significant amount  energy  and proper switching arrangement should be there to switch on and off when it required light and when does not required  to save energy as due to mis use a lot energy is wasted in our street light.

alternatively we should try to utilize other alternative renewable energy like solar power/wind power/ Bio-gas power etc for street light to save our conventional energy in long term.
