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 email.

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.

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.



The DIALux User Interface

These three work areas enable effective and clearly arranged planning of lighting

installation with DIALux.

.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.

Quick Street Planning Wizard

This wizard guides you through the quick planning for streets.

you will find the wizards in

the menu File >> Wizard



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.



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.



Start Calculation

Afterwards a final dialogue will appear automatically. If you activate the checkbox, the generated

street will be calculated immediately.

Click on the Finish button and your street project will be displayed.

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

Decide the road classification and required E

according to street lighting standards

av and Uo

5. Existing mounting height or pole distance?

Information needed for lighting simulation



Step 2: Edit street in DIALux

Arrangement of street component according

to the road information.



Step 3: Decide which LED

CCT: from 5000K-6500K (LW, LUW)

(color bin and brightness group)

If need CCT from 4000K-5000K, can be mixed by LUW and LY.

No need of secondary

optical design



Golden DRAGON Plus

Need lens or reflector

Higher brightness

Step 4: Change luminous flux

You can change the luminous flux and power here.

It’s related to how many LEDs in one lamp.

Step 6: Optimize arrangement parameters

Optimize arrangement parameters

Boom Length

(1) Mounting Height: 6m~10m

(2) Overhang: 1m~2m

(3) Boom Angle: 10 ฐ ~15 ฐ

(4) Boom Length: 1m~3m

(5) Pole Distance

These parameter will be optimized

according to street profile to achieve

best performance: Eavand Uo.

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.
