Lighting design becomes a big field recently, and if Architect or Engineers wants to design lighting, they should learn many things about lighting, lamps, optics, colors , control system and calculation using 3ds Max or DIALux and the difference between radiosity calculation and ray tracing rendering
For me ERCO Guide is one of the best resources I have ever found for learning lighting design
but there is one difficulty using this guide, as the guide is rich of useful information, it might be difficult to use.
here bellow is an example how to use ERCO Guide
1. First of all go to www.erco.com and then chose Guide as shown on the next Image
2. In the guide you will find many interesting topic I recommend that you go through all of it, but for this example chose outdoor lighting as shown in the next Image.
3. go down the page and chose entrance area large as shown form next image
4.notice that there is many links in each page, press the Planning link as could be seen form next Image
5. you can find many design options, you can select between them and read the design concept and you can also see the arrangement of the luminaries .
this is only one example, this guide is really full of good information and arranged in a perfect way
But what is really cool that in the download section you can download the whole Gudie as A PDF file for free!
