Per limitare la luminosità artificiale del cielo in un territorio e minimizzare efficacemente la quantità di luce artificiale diffusa nell’atmosfera é necessario porre limiti all’intensità dell’emissione degli apparecchi sopra i 90 gradi in modo da renderla trascurabile rispetto quella delle superfici, in particolare a piccoli angoli sopra l’orizzonte. Per renderci…
We present the results of a comparison of light pollution produced by some light installations for roadway lighting as obtained with the software Roadpollution. Luminaires with an direct upward flux factor apparently as small as 0.2% and 2.2% produce increases of light pollution even of the order of 20% and…
