Dad, what is the Milky Way?
Dad, why can’t I see the Milky Way?
BECAUSE OF LIGHT POLLUTION
Globe-type luminaires, those with concave glass and those that are not directed parallel to the ground shine light towards the upper atmosphere and contaminate the sky.
BECAUSE OF SHORT WAVELENGTH LIGHT EMISSION
White and blue light has a high level of dispersion into the atmosphere that causes light pollution. Warm and red light with a longer wavelength causes less light pollution.
Light Pollution: Theory, Modelling and Measurements
From 27–30 June in Cellers, Lleida, a conference will be held on light pollution, at which Ignialight will be a Gold sponsor.
Better lighting rather than more is needed
Our society needs lighting. For years, lighting has been unchecked, excessive, and quite often no efforts have been made to seek the most efficient and environmentally friendly technology. The time has come to raise awareness about this and to protect the environment using the most efficient technology to do so.FOR A DARKER SKY
