1 - INTRODUCTION
What is Easy Light - Save the Sky?
Save the Sky, in spite of its name, is a light design software aimed to beginner and experts alike. Its purpose is to optimize the design of road lighting. It can, in the respect of security technical norm and rules:
- Optimize the interdistance (distance between poles/pole height) of fixtures;
- Minimize the installed power per street length,
- Minimize the minimum maintained luminance;
- choose the better fixtures and make the most of them;
- Release > 4.0 also optimization of cicles-pedestrian and street light plants
- Last but not least lower the direct and indirect light flux aimed at the sky (as requested by the most effective laws against light pollution like the Italian regional Lombardy law).
Achieving these goals allow us to light roads respecting the night sky and its cultural heritage of incalculable value for us and future generations.
Usually in other light design software, the designer chooses the street and installation parameters, then he compares if the processed results meets the technical rules. The design is done.
This software, chosen the street dimensions and the values imposed by the rules, optimize the calculus variables (like pole heigh, distance, tilt and so on) in order to produce the best configuration needed.
More important characteristics
This software take into account the Italian norm UNI 10439, revision July 2001, on motorized traffic roads and follow the prescription of CIE 30 and EN13201.
Every software uses slightly different algorithms due to technical reason (referencing to CEI 140-144 o other technical rules) or due to different interpretation (a big fraction of the commercial softwares seems to have different interpretation of the technical rules and some of them commit mistakes).
Testing Save the Sky, we compared the results given by some of the best lighting softwares and we found only slight differences between the programs (around 2 or 3 % on luminance, sometimes higher on uniformity, probably due to position of the chosen observer).
The reference softwares used in the testing of Save the Sky are: Relux 3.0, ewoEXCALC 1.01.03 e LiteStar 4.1 e 5.0, Dialux 4.5
2 - DOWNLOAD Easy Light - Save the Sky
If you want to download, you can choice between:
1- The full version: Easy Light - Save the sky plus the photometricals data
2- ONLY the Software (without photometrical data)
3- ONLY the photometrical data
EASY LIGHT - SAVE THE SKY ver. 4.0a (full version also for 64bit: Easy Light - Save the sky plus the photometricals data) - about 13Mb
1- Download Easy Light - Save the Sky in you Hard Disk in a blank folder,
2- Execute WinZip (download at the botton page) to Extract the program files
3- Execute setup.exe to install Easy Light - STS (use if possible the default folder),
4- Execute Easy Light - Save the Sky
5- In the first windows, only the first time, the software request the folder where to extract the eulumdat photometrical data and the Products Data Base. Press only to start the extraction.
6- You are ready to make your lightings projects!
Eulumdat for EASY LIGHT - SAVE THE SKY (only photometrical data) - about 8Mb
Photometrical data catalogue
This new version is Multilanguage (English, Italian, French and Spanish) with help in three language (Italian, English and French) and with more than 3600 photometrical data (with emission over the horizon < 1cd/klm). We thank's the Producer and the distributors that thay decided to partecipate to this project: Cariboni, Comi - Eclatec, Comi - Ge, Disano, Ewo, Fivep, Ghisamestieri, Grechi, Hess, Leuci, Philips, Schreder, Siteco, Till, Thorn.
1- Download the photometrical data Database in your Had disk directly in the Easy Light - STS program folder
The first time:
2- Execute Easy Light - Save the Sky
3- If Easy Light - STS dont' find the photometrical data, the first windows of Easy Light - STS request the folder where to extract the eulumdat photometrical data and the Products Data Base. Press only to start the extraction.
The other time:
2- Execute ldt.exe
5- In the first windows, only the first time, the software request the folder where to extract the eulumdat photometrical data and the Products Data Base. Press only to start the extraction. If the folder of the file ldt.exe is different to the Easy Light - STS folder, after to press do you set the right Easy Light - STS program folder.
6- You are ready to make your lightings projects!
