The light is not utilized, which often exceeds 25% in some cases exceeded 50% (balloon-type lamps), we also have to pay. Obliges us to use higher power lamps are used as only a part thereof, the remainder being lost unnecessarily. This excess of consumption that must supply the power stations, is more fuel consumption and, consequently, higher emissions of polluting gases into the atmosphere, among other things responsible for the greenhouse effect is increasing the average temperature of our planet and acid rain that destroys forests.

Glare:

Light falling directly from the lamp in our eyes has an intensity well above that comes reflected from the ground and the obstacles it presented, we see them doing worse since the opening of the pupils has closed to adjust to that light intensity. Read the rest of this entry »

What is light pollution?

It is all the light that is emitted or escapes above the horizontal of the light in an installation of outdoor lighting. It produces a bright halo or glare on the stock, by illuminating the particles of dust or water the air contains suspended. When there are clouds, the basis of these is illuminated.

We will extend this definition considering how light pollution to all the light that leaks out of the area you want to illuminate, ie, all the wasted light energy, directly or indirectly after it has harmful effects on the environment. Read the rest of this entry »

CHARACTERISTICS AND USE OF LUMINAIRES:

The criteria to follow in choosing the luminaires to achieve efficient outdoor lighting, can be summarized in these three basic rules:

NEVER BE LIGHT FROM THE MOUTH OF EXCEL REFLECTOR

The beam of light produced should not extend outside the area that we need light, Read the rest of this entry »

Energy waste:

The light is not exploited, which often exceeds 25% and in some cases exceed 50% (balloon-type lamps), we also have to pay. It forces us to use higher wattage lamps because we are only using part of it, lost the rest unnecessarily. This excess of consumption that should supply the power plants, leads to an increased fuel consumption and, consequently, increased emission of pollutants into the atmosphere, among other things Read the rest of this entry »

Light pollution caused by inefficient use of Towards the sky and poorly designed lighting, which sends light into areas where it is not necessary: it. The use of projectors and laser weapons, advertising uncontrolled lighting, and lack of rest period decorative lighting that also helped to produce this problem.

We must warn that there is also light pollution by using excessive light intensity, and / or ratings that do not need to carry out activities under the area illuminated.
