3 What is special about DIALux? DIALux - a planning software for your project presentation. Calculation: latest radiosity procedures, fast and always correct. Results: Results can be printed out or transmitted as a pdf file. Each view and each rendering can be saved as a.jpg file. Interactive 3-D visualization: Simply move around the room. Visualization: Use of textures and furniture for realistic rendering. Photo realism: with integrated raytracing module. False colours: False colours provide quantitative analysis of complex geometries at a glance. Movies: Walk through the photo realistic visualization of your light planning and send the film to your customer via . Interaction: Import and export:.dwg and.dxf files can be imported and exported with results after completion of the planning process. DIALux Light: Easy to use, step-by-step lighting design.

4 Free Download DIALux from website Download the DIALux Setup (version DIALux ) from homepage ( or on your hard-disk. Language available or deutsch english français italiano español 中文 Download file size: about 250MB Event / Title December 17, 2008 Page 4

5 Online Update If you have already installed old version of DIALux, you could use online update to newest version. In DIALux you will find a new menu named Online. After selecting Online Update DIALux automatically checks for newer versions of the software and for new online PlugIns. But it will take some time to finish update.

8 .IES or.idt files.ies or.idt file describe the information of light distribution, luminous flux, and power..ies or.idt file are very small ( only about 10K) compared to ray data (about 200M). OSRAM OS provide both.ies (or.idt) file and ray data of our LED products on website. Event / Title December 17, 2008 Page 8

12 Quick Street Planning Wizard This wizard guides you through the quick planning for streets. you will find the wizards in the menu File >> Wizard Event / Title December 17, 2008 Page 12

13 Street profile and illumination class Street profile Street name and maintenance factor are likewise inserted on this page. In the following window you can fix the individual or combined valuation fields for the street. In order to define photometric requirements for the street, select an illumination class for every valuation field. Event / Title December 17, 2008 Page 13

14 Luminaire arrangement In the window Luminaire arrangement you can select a luminaire and place this in an arrangement. (You need to import the IES file of OSRAM LEDs first, otherwise you can only select the existing traditional luminaire in DIALux) You can optimize the arrangement parameters depending on the predefined photometric requirements.

20 Step 1: Collecting road information Street profile, width, N of lanes, coating Information list before design: 1. Street location and photos 2. Width of street 3. N of lanes 4. Coating material 5. Existing mounting height or pole distance? Decide the road classification and required E av and U o according to street lighting standards Information needed for lighting simulation Event / Title December 17, 2008 Page 20

21 Step 2: Edit street in DIALux Arrangement of street component according to the road information. Event / Title December 17, 2008 Page 21

22 Step 3: Decide which LED (color bin and brightness group) CCT: from 5000K-6500K (LW, LUW) If need CCT from 4000K-5000K, can be mixed by LUW and LY. Golden DRAGON with Oval Lens Golden DRAGON Plus No need of secondary optical design Need lens or reflector Higher brightness Event / Title December 17, 2008 Page 22

23 Step 4: Change luminous flux You can change the luminous flux and power here. It s related to how many LEDs in one lamp. Event / Title December 17, 2008 Page 23

24 Step 5: luminaire arrangement Normal methods of luminaire arrangement Lighting Class Single row Double row, with offset Double row, opposing Single row Double row, opposing Double row, with offset Road information Uniformity W 6m N 2 0.4~0.5 W 8m N 2 0.5~0.8 W 16m N 4 0.5~0.8! Rules of thumb Luminaire arrangement will be decided based on street profile requirements Figure For LUW W5JM, Double row, opposing was recommended. Event / Title December 17, 2008 Page 24

25 Step 6: Optimize arrangement parameters Optimize arrangement parameters (1) Mounting Height: 6m~10m (2) Overhang: 1m~2m (3) Boom Angle: 10 ~15 (4) Boom Length: 1m~3m (5) Pole Distance Boom Angle Mounting Height Boom Length These parameter will be optimized according to street profile to achieve best performance: E av and U o. If a certain Uo was required, the most economic mounting height and pole distance could be optimized. Lower distance, longer pole distance could save energy and pole cost.
