DLX-T8 some features in DIALux evo

DLXThis tutorial highlights some features

If you don’t have any experience with DIALux evo, I advise you to start with DLX-T1 which explains more basic function of the software that might not be explained here, DIALux evo Tutorial 4  could be found @


Also you could see DIALux evo Tutorial DLX-T2


 Image Once you download the file setup you will find two versions 32 bit and 64 bit64 bit is faster for complex projects but cannot import DIALux 4 project so if you are dealing with complex project it would be good.
Feature 1- real time light visualization  
 Image One of the nice addition in evo 3 is the show light visualizationThis feature enables you to see on real time the light where you can adjust the light as required before you run the calculation.You can activate this feature form the display option in the upper right corner.
 Image Once the Show Light Visualisation is activatedSelect any light to see its light.If you select a spotlight with tiltable head then you can tilt the head and see the difference in real time.

It is not only for tiltable luminaire but you can see the light once you select move rotate any luminaire.

 Image With this feature you can have perfect distribution before calculation!
Feature 2- evo easy  
 Image This feature is very good for beginners and for quick calculation of a simple room.You can start a room quickly form the start window interface.
 Image You can enter the room size quickly and you don’t get the other icons which could confuse the user.
 Image On the light you can quickly add automatic arrangements for spaces.Again the interface is simplified to make options limited to avoid confusionsThen you can calculate and see an easy report on the documentation
 Image If you want to switch back to full options and see the other functionalities you can do that after creation of the room form the upper right corner drop menu
Feature 3- Energy assessment  
 Image You can now see the energy consumption form the display options in the upper right corner.
 Image Form light mode you select the energy consumption iconhere you can adjust the default values of the time and space typeyou can also insert energy sensor which could reduce the consummation.
 Image From TachometerLENI which is kWh/year/m2total assumption per year kWh/year

the cost where you have to put the tariff and the currency symbol

Feature 3- HDR image export  
 Image From calculation mode- Reytracer icon you can save output of the view as HDR image.You can only do that after calculation.
 Image You can make the resolution higher before export
 Image many software support HDR like photoshopbut if you don’t have HDR viewer you can download a free software like Picturenaut form the following link:http://www.hdrlabs.com/picturenaut/index.html
 Image The advantage of HDR is that you could adjust the brightness of the image
 Image In Picturenaut you can adjust the brightness form the lower left corner slideYou can also make it Auto.
Feature 4- Street calculation
 Image In evo3 you can do street calculation using the Scheme editor
 Image You can select the Illuminate conditions based on the following table
 Image In the Street Profile if you select the roadwayYou can edit the name width the CIE SurfaceYou can also adjust the direction of travel for each lane.
 Image From Street profile you can also add different lane as sidewalk and move them by arrow
 Image By selecting each lane you can modify the lane properties
 Image If you select the valuation fieldsYou can select the Illuminance class for street and each other lane.To get more information on street lighting standard check No. 03 „Roads, Paths and Squares” by http://www.licht.de/

Under the following link


I hope next versions of evo will have the selector options window as DIALux 4 Street wizard

 Image In the planning mode you can add road luminaire arrangement
 Image You can select other types of luminaire and added as a variant.The optimization will give you the best possible luminaire with the best possible arrangement to achieve the required luminance
 Image If you select a luminaire you can put the arrangement type as one side tow side staggered of in the middle.You can also optimize the pole distance (distance between luminaires) by putting the max, minimum and steps of distance for optimization.This information will be calculated by the DIALux evo to give you the best possible result.
 Image You can also optimize other parameter like the luminaire height, arm distance , tilting of luminaire, the more values for optimization the more time will take for calculation.You can optimize many luminaires to see what the best arrangement and light distribution that suits the street condition.
 Image Start optimize all schemes to see the results
 Image After optimization is done then you can see the results form the result mode.You can hide the insufficient items form properties.You can also export the file as CSV and view it in excel or similar software.

DIALux will automatically select the best result with maximum distance but if you wish to select any other situation then click on it to appear in the documentation.

 Image In the documentation you can have the report with pole configuration and required and achieved values.
Feature 5- adding luminaire for all spaces
 Image If you select story or building view you have the option to put one luminaire in the unit spaces.That could be usfuel if you have one luminaire type for all rooms , this is not new to evo 3 but I thought it is good to highlight it here .

Feature 6- Adding the room layout in the room summary.

 Image Now the room layout is generated in the room summary like DIALux 4
I am sure there are other improvement but those features are the most useful in my opinion

  8. I have a question regarding export to excel. I have seen that I can export the list of all the luminaires used and the quantites of each room. But I can’t seem to find it and I have googled it everywhere.
