Traffic lights last generation to care for the environment (28/04/2009)

In order to improve environmental quality throughout the municipality, the City of Cartagena is carrying out the progressive replacement of all traditional traffic lights, which worked with halogen lamps for traffic signals that use a technology called LED (Light Emitting Diodes or LEDs).

This new model includes a multitude of tiny lights colored lights, which together generate a similar effect as they had prior to the reflector halogen bulb behind a colored (green, amber or red).

The advantages of this new technology versus the traditional light are varied, and the fact that consumption is reduced by between 80 and 90 percent, plus they have a lifespan of 10 years, while the duration of conventional lamps was about 6 months.

They also offer greater security since they emit light with high brightness and away the spotlight that have the conventional traffic lights to avoid being dazzled by the sun, the effect is known as 'ghost'.

On the other hand, possess more than 100 light bulbs that failure prevents any traffic light signal turns off.

With regard to energy saving and environmental impact, it is estimated that if the daily consumption of the traditional lights was 5,108 kW 8,581 / day with a result of emissions to the atmosphere of 3.287 tonnes of CO2, with the new technology being implemented will to 1225.92 kW / day with a result of emissions of 0.47 tonnes of CO2.

The project will last approximately two months and will be held without charge by the City Council and has been funded by IDEA (Institute for Energy Diversification and Saving of Energy).

The installation will be made by the company MURTRAFIC.
