- solar street lamp

Daily Mail reporter UPDATE: At 03: 42 on July 21, 2011, the British Parliament will cut costs and save thousands of pounds in energy costs after launching the first LED power street lamp in the UK.
Bath and the North East Somerset Parliament are taking the lead in action and have installed eco-friendly lights on the island of sixmen roundabout at the end of Somerset Keynsham Bristol.
These lights are expected to save taxpayers more than £ 4,500. each-year -
And 25 tons of carbon emissions.
Bright white LEDs provide clearer and better lighting than traditional street lights, improving conditions for cycling, drivers and pedestrians.
Each lamp contains more than 80 small bulbs, which have a life of 60,000 hours or about 16 years when lit 10 hours a day
Five times the traditional street light.
Roger Simmonds, Minister of Transport at Bath and North-East Somerset parliament and liberal Democratic MP, said LED lights made roads safer.
Simmonds, 69, said: "We know that this is the first time that the country has used this technology on major traffic routes.
"The lights automatically adjust the brightness level based on the time of day and the number of vehicles on different time routes at night.
The end result is that Bath and the North East Somerset Council save money on behalf of local taxpayers and reduce our carbon footprint, which makes the route safer because for drivers and cyclists, the light will illuminate the carriage more clearly.
Bath and North East Somerset used 250 watts of high-pressure sodium lighting on the island of Hicks Gate before.
In June 10, they were replaced by 169-watt LED lights.
Thanks to dimming technology, it immediately saves energy and again.
It will take eight years for the LED lights to reimburse the manufacturing and installation costs of the current £ 36,000.
The trial will end by the end of this year.
A spokesman for the highway administration, which manages highways and major A roads, said he was not aware of any incidents that had previously used LEDs on the main roads.

Street lamps are currently not widely used on strategic road networks, although this is a technology that the agency does consider where the lighting standards are met and where there is value for money for public wallets.
