DIALux 4

Versionhistory

DIALux 4.13

 

  • Bug fixes

 

DIALux 4.12

 

  • Bug fixes

 

DIALux 4.11.0.1

 

  • Integration of Danish street norms. 
  • Extension of the DXF/ DWG library: Now DWGs created with AutoCAD 2010 can be imported into Dx. 
  • The maintenance factor for the street and the street surface including Q0 can now be set globally as a standard value. 
  • When a geometry tab is deleted, a confirmation prompt appears in the street plan editor. 
  • Geometry tabs in the street plan editor can be renamed. Geometry tabs in the street plan editor can be sorted. Geometry plans in the street plan editor can be duplicated. 
  • Optimization for Esc/Ev in the street’s S-lighting classifications is activated automatically. This means that whenever there is a change in the lighting classification, the default values are activated automatically.
  • Dx can now import absolute LDTs. 
  • CSV-Export for the street plan editor has been implemented. Now all the information which the street plan editor has is exported. This means that the output of a geometry description with grid information and all the values of the table ( e.g. requirements such as min. and max.) is generated.
  • New translations within the street plan editor. 


Bug fixes:

  • The output problem of blurred/fuzzy graphics and of large PDF files after export has been remedied. This was caused by the Internet Explorer 9 and 10 (pre-release). 
  • Improvement in the output for lighting classification. 
  • The problem when adapting the lighting clasification has been remedied. 
  • Further bug fixes in various translations. 



DIALux 4.10.0.2

 

  • DIALux 4.10.0.2 is a forerunner of the DIALux evo version. After installation the feature for importing DIALux indoor room projects is activated in the DIALux evo menu. 
  • In some cases DIALux projects could no longer be loaded in older interim versions. The problem of downward compatibility has now been solved. 



DIALux 4.10.0.1

 

  • In the last version of DIALux the specification for luminous flux was changed. DIALux 4.10.0.0 no longer displayed the luminous flux of the lamp but instead the luminous flux of the luminaire. Many users were unhappy with this, because for their documentation they also required the luminous flux of the lamp. With our latest update we have taken this frequently expressed wish into consideration and now in the list of items display the luminous flux not only of the luminaire but also of the lamp. For absolute photometric data these values are identical. 
  • The setup had to be adjusted because of the operating systems supported by DIALux. For systems which have already been installed there is no change: Future updates will not cause any problems. 


Bugfixes:

  • Sometimes when the list “luminaires last used” was full it was not possible to start the DIALux Light Assistant or the selection of the luminaire caused the system to crash. This fault has now been remedied. 
  • When transferring information into street scenes the new “Street Plan Editor“ sometimes transferred non-initialized values wrongly. This led to deviations between the Editor and the results of the final calculation. These problems have been remedied. 
  • Our customers informed us that certain translations in the new Editor were unfortunately not quite correct. These have been corrected. 



DIALux 4.10

 

  • With the Street Plan Editor it is now possible to create, calculate, optimize and compare street light plans incredibly quickly and to see them clearly presented next to each other. Alternative positions and products can be tried out next to each other and the results are available in real time. So it is now possible within one street geometry to compare any number of variations. If however different street geometries have to betaken into consideration, this can be done using several parallel diagrams. 
  • EN13201 is under revision. In contrast to the existing norm this will require two positions after the decimal point. This was not the case before but in some countries this was normal practice despite the norm requirements. From the 4.10 version onwards calculation of street lighting will require two positions after the decimal point. This will affect the rounding up or down of the results and consequently the fulfilment of the criteria. Plans which previously fulfilled the requirements may now fail in certain cases. 
  • In Denmark street lighting is calculated rather differently from in the rest of Europe (Vejregleme for vejbelysning). Since these deviations have very clear effects on the calculation, DIALux has now been fully adapted to the Danish norm. The calculation model is similar to the European model in EN 13201, so this is not a specific Danish method (as or example in the choice between IESNA RP8 and CIE140/EN13201) but “only” a further illumination category within the EN13201 method. The Danish classifications can be identified by the abbreviation “DK”. 


Optimizations:

  • The initial value for the maintenance factor in street lighting has now been changed to 0.67. 
  • The display of manufacturer names with Chinese symbols is now correct. 


Changes:

  • The number of users with Windows 2000 is negligible. Nevertheless DIALux versions up to and including the 4.9 versions supported this operating system. Changes in technology on the part of Microsoft have now made changes necessary in DIALux which no longer enable support of Windows 2000.From the 4.10 version onwards it will no longer be possible to use DIALux with a Windows2000 system. 
  • With the development of LED lighting and the absolute photometry frequently used here there is no luminous flux for the lamp in such lighting products since there is no lamp in these luminaires. In the luminaire parts lists the luminaire wattage and (new) the luminous flux of the luminaire are shown. This leads to comparable values not only for LED luminaires but also for luminaires with conventional lamps. 



DIALux 4.9.0.1

 

• Korean has now been added to the languages in which DIALux is available. Optimizations:

  • There were problems with 64 bit systems when creating outputs as PDF files. This problem has now been remedied. PDFs can now be created on both 32 bit and 64 bit systems.
  • Unfortunately, in the 4.9.0.0 version the input of room coordinates did not work in the room editor and for this step a right mouse click in the CAD was required. It has been possible to correct this malfunction. 
  • With 4.9 it is possible to position and align floodlighting using a chart. This very comprehensive tool makes it possible to make all kinds of adjustments to the positioning. Howeve, in the luminaire column the description was missing. This has now been added. 
  • When editing floor elements there was a possibility of the programme crashing if two points lay directly above one another. This malfunction has now been corrected. 
  • In DIALux light the minimum height for the working plane was 0.1m. This has now been reduced to o.01 m. 
  • The standard value for the distance between the pole and the traffic lane in street lighting has been changed from 0.5 m to 0.65m.
  • The option of rotating the LDC by 90° within the geometry of the luminaire has been deactivated for luminaires from plugIns (ULDs). This function is not necessary since the manufacturers have already carried out correct positioning of the LDC in the plugIn. 



DIALux 4.9

 

  • Gbxml Import. This data format enables import of building information such as walls, ceiling, floor, windows and doors directly into DIALux. All modern CAD systems (AutoCAD MEP und Revit, Bentley, Nemetschek, Graphisoft…) are able to export this format. In this way all the rooms in a building can be constructed from the outset with windows and doors ready for further editing in DIALux. Adding the geometry for theses features often used to be time-consuming, but now this is no longer necessary. 
  • Different photometric standards apply in North America (IESNA) and Europe (EN) when setting the alignment of a streetlight during light measurement. In the IES standards a street light is oriented for measurement with “Horizontal 0” (the equivalent to level CO) so that it is directed into the street, namely at a right angle to the edge of the kerb. In Europe (and also in Asia and Australia) however level CO is positioned parallel to the kerb and the course of the road. Unfortunately it is not possible to correct this automatically with software. The necessary information is simply not available for automatic correction. For this reason a further function has been added to the import of luminaire data (EULUMDAT and IES). While data are being imported, it is now possible for the user to adjust the alignment. Of importance here is that it is possible to rotate the light distribution curve without distorting the geometry of the luminaire. However, if required, the geometry can also be adjusted at this stage. This is important since the IES data only define the light output area but not the luminaire housing. 
  • Street planning in accordance with the US street standard IESNA RP-08-00. For the illumination of roads the US standards differ enormously from the standards in Europe and many parts of Asia. This not only affects the nominal values to be achieved for luminance density, illuminance or uniformity but the way of determining the parameters is completely different. In DIALux 4.9 the user can now select whether to plan according to IESNA or CIE/EN. Of course, for planning according to IESNA the planner still has access to the optimizer. In just a few seconds DIALux can find the optimal luminaire and its position for a given street. 
  • Storing in the street plan optimizer and quick street planner. The parameters in the optimizer can be stored and used for new street planning on restarting the optimizer. So the planner can start again where he left off without having to re-enter all the parameters. 
  • Removal of the restriction for tilting (LDT, assembly types). When using EULUMDAT or IES data, and also for wrongly defined luminaires in plugIns DIALux does not allow the optimization of the tilting angle. Since technically only luminaires mounted on the side of lampposts, in rare cases also on top of the lampposts, can be used, this was not possible with imported luminaire data. 
  • Export of optimizer results in a CSV (Character Separated Values) file, e.g. for further evaluation in Excel. Previously the result list of the optimizer was only available to the user as an overview for selecting the desired option. This result can now be stored as a file for further use. This can be used either for documentation or for a further analysis, which also includes assembly, purchasing and operating costs etc. . 
  • The selection of several luminaires for optimization was somewhat confusing and many users found this too complicated. This is now much simpler and more clearly structured. 
  • Chart input options for luminaire layout in sports complexes. To improve the editing of sports complex lighting there is now a chart function in DIALux 4.9 which simplifies the positioning of the luminaires. Many experienced light planners who are familiar with the illumination of sports complexes wanted to have this function in chart form and not just as a graphic display. Those planners who do not yet have so much experience in this area of planning will continue to find the graphic positioning much faster for their purposes. With the chart function floodlighting can be positioned exactly by entering the position and the aiming angle or aiming point. Exchanging the luminaire or the lamp is also very easy with this function.
  • Output of the Australian standard IEQ-7. Energy efficiency is now an important topic all over world. So it is not surprising that in many countries regulations on this are being passed. In Australia the “Green Building Council“ has issued a technical manual “Green Star Office Design & Office as Built“. The IEQ-7 section deals with luminance intensity. To achieve the required results you now no longer need to start complex calculations but simply click the appropriate check box in DIALux. 
  • Concealing objects. Via the context menu objects can be concealed. The objects marked are concealed via the menu item “Selection invisible” and shown again via the command “ Cancel invisibility”. This function enables a clearer overview when working on complex projects. 



DIALux 4.8

 

  • The implementation in DIALux of the parameter modifications for calculating energy requirements in accordance with EnEV2009 is now complete. DIALux complies as always with the latest directives and guidelines. 
  • DIALux has been fully adapted to the requirements for handling absolute photometry. The US IES LM 79 Standard prescribes guidelines for documentation and preparation of photometric data for SSL luminaires (solid state lighting/ LED luminaires ). One of the main modifications in the latest version enables documentation of these data in DIALux. So DIALux continues to be 100% LED- compatible. 
  • DIALux has now been fully adapted for the handling of lamp plugIns. The OSRAM lamp plugIn has been available since Light and Building. The lighting designer planner can now select suitable lamps for the luminaire which has been chosen. When complete luminaire catalogues are used, the luminaire “tells” the lamp plugIn which lamp to use. Thus the designer is able to react to the different requirements during planning and select the most suitable amps with regard to luminous flux, light colour, angle of the light beam, life cycle etc. 
  • One of the key features of DIALux street lighting is the opportunity to maximize the lighting with regard to the maximum distance between poles, the height of the pole or the type of luminaire fixture. This function has been enhanced to meet Danish and South African specifications. DIALux will continue to be adapted to meet all international requirements.


Optimization:

  • More improvements in converting between metric and imperial dimensions (ft <-> m and fc <-> lx)
  • When large numbers of ground elementss were used for planning outdoor scenes, memory problems sometimes occurred. This has now been remedied. 
  • When very large areas were selected for printouts, there were also memory problems. This has also been remedied.
  • Minor bug fixes and modifications. 



DIALux 4.7.5.2

 

  • A new DXF/DWG library was integrated in DIALux. Now it is possible to read in also those DWG /DXF files which are saved with AutoDesk AutoCAD 2010. 
  • In some PropertyPages the wrong units were displayed while using imperial settings (ft, fc, ...) instead SI units have been displayed. 
  • Using PovRay and luminaire models with rotatable elements in seldom cases the light distribution was tilted. This bug is now solved. 



DIALux 4.7.5

 

  • The calculation of daylight situation has been improved. The speed and the accurateness have been increased once again. 
  • The internal DIALux Ray-Tracer, first implementation in DIALux 4.7, is subjected to a continuous improvement process. With an articulately increased rendering speed, colours will be shown more naturally and with higher colour saturation. The faded or pallid seeming pictures having similar colour saturation like “standard” 3D renderings now. 
  • Optimization of the DIALux calculation kernel to calculate small surfaces much faster. 
  • The results of the energy optimization for the illumination system according DIN V 18599 respectively EN 15193 will be shown in the property pages in real-time yet. This feature makes switching to the printouts during optimization needless. 
  • DIALux runs in imperial units for light engineering and dimensions automatically, if an US operating system is recognised during the program start. Furthermore the decimal places for illuminance classes are adapted. 
  • Adjustments of translation texts 
  • Smaller bugfixing and improvements 



DIALux 4.7

 

  • Visualization: The presentation of transparency and specular reflection was previously only possible in the raytracer procedure with the POV-Ray supplied with DIALux. Now both are also supported directly by DIALux. Simply allocate the most suitable material property to each object used. The Raytrace Preview has been added to the DIALux views. This provides the same functionality as POV-Ray but with improved quality and rendering speed. 
  • Calculation: Previously it was not possible to calculate transparency.Only POV Ray could present the visualization – but without calculation results. The optimized calculation core used by DIALux can now calculate transparency. In this way you obtain the correct results. The new Ray Trace Preview is responsible for the visualization (see above). 
  • DIALux provides a new object for the new transparency calculation option. The “glass plate” has been added to the standard bodies. The benefit of this is in the already preset material properties. Of course there is the option of adjusting the degree of transparency and the specular reflection individually. 
  • Creating videos: Now the new material properties such as transparency and specular reflection can be taken into account for films. In this way you can make your presentation even more realistic. 
  • Calculation grid: In addition to luminous intensity values the real time calculation of calculation grids now also displays the uniformity Emin/Emedian and Emin/Emax in the CAD views. 
  • DWG/DXF Export: To DWG and DXF Export have been added sports complexes, calculation grid results, C0-alignment and alignment arrows. This information can now be exported as a separate individual layer.
  • There are new output pages for radial calculation grids such as, for example, circular paths or tracks and also for free calculation grids. The improved presentation is displayed with “radial table” or “point value” output pages. 
  • Street lighting: The lighting categories for roads now also support Danish and South African norms.
