There are places in this world where people are now in the street demanding their rights and money. Why shouldn t they benefit from a green light in the evening instead of the white or of the yellow one ?? Till the governments and world leaders find a solution to the present extended crisis, why shouldn t the administrations take care to save some long term money making some immediate healthy investments ? So, what s the point, you will say. And I say this web page gives an idea about what some of the human beings did recently and about what the rest of us could or would be able to do.
If the domestic energy consumption is monitored now by efficient light bulbs, not the same thing can be found extensively outdoors.
So, a solution is on its way for this too. Both sodium and halide lamps of the streets are going to be replaced by LED lamps which offer a wonderful more economic and powerful...GREEN light...!! And this is not neglectable...! An American school of profile found the used power of the green light is a half of the one used by the standard ones. Pittsburgh has already ordered 40000 of such lamps and it is followed by Los Angeles and San Francisco. Ann Arbor found important savings from using them, around one million dollars, arising not only from the cost itself but an almost equally amount from the diminished necessary maintenance.
In Europe, this technology is still on probation but it seems to be analyzed at a really outstanding level. Namely, Poland, Portugal, Latvia and France are going to adopt a LED type lamp which modifies the intensity of its light in accordance with the necessary environmental illumination so that it is offered the best level of visibility. In the UK, the innovation award won in 2008 by the Southampton Airport was for the implementation of LED lamps for its own outside buoyage, the system being estimated to last 10 years and to reduce the carbon emissions at more than a half, diminishing also substantially the heating and dazzling effects.
And we can be happy to know that the provider of these LED lamps is now on its way to seriously extend this system in malls, health centers, all over the United Kingdom...
